  1. Electric-utility DSM programs in a competitive market

    Energy Technology Data Exchange (ETDEWEB)

    Hirst, E.

    1994-04-01

    During the past few years, the costs and effects of utility demand-side management (DSM) programs have grown sharply. In 1989, US electric utilities spent 0.5% of revenues on such programs and cut total electricity consumption by 0.6%. By 1992, these numbers had increased to 1.3% and 1.2%, respectively. Utility projections, as of early 1993, of DSM expenditures and energy savings for 1997 were 1.7% and 2.5%, respectively. Whether this projected growth comes to pass may depend on current debates about deregulation of, and increased competition in, the electric-utility industry. This report examines the factors likely to affect utility DSM programs in a more competitive environment. The electric-utility industry faces two forces that may conflict with each other. One is the pressure to open up both wholesale and retail markets for competition. The net effect of such competition, especially at the retail level, would have much greater emphasis on electricity prices and less emphasis on energy services. Such an outcome would force a sharp reduction in the scale of DSM programs that are funded by customers in general. The second force is increased concern about environmental quality and global warming. Because utilities are major contributors to US carbon dioxide emissions, the Administration`s Climate Change Action Plan calls on utilities to reduce such emissions. DSM programs are one key way to do that and, in the process, to cut customer electric bills and improve economic productivity. This report discusses the forms of competition and how they might affect DSM programs. It examines the important roles that state regulatory commissions could play to affect retail competition and utility DSM programs. The report also considers the effects of DSM programs on retail electricity prices.

  2. DSM and electric utility competitiveness: An Illinois perspective

    1994-01-01

    A predominant theme in the current electric utility industry literature is that competitive forces have emerged and may become more prominent. The wholesale bulk power market is alreadly competitive, as non-utility energy service providers already have had a significant impact on that market; this trend was accelerated by the Energy Policy Act of 1992. Although competition at the retail level is much less pervasive, electric utility customers increasingly have greater choice in selecting energy services. These choices may include, depending on the customer, the ability to self-generate, switch fuels, move to a new location, or rely more heavily on demand-side management as a means of controlling electric energy use. This paper explores the subject of how demand-side management (DSM) programs, which are often developed by a utility to satisfy resource requirements as a part of its least-cost planning process, can affect the utility's ability to compete in the energy services marketplace. In this context, the term 'DSM' is used in this paper to refer to those demand-side services and programs which provide resources to the utility's system. Depending on one's perspective, DSM programs (so defined) can be viewed either as an enhancement to the competitive position of a utility by enabling it to provide its customers with a broader menu of energy services, simultaneously satisfying the objectives of the utility as well as those of the customers, or as a detractor to a utility's ability to compete. In the latter case, the concern is with respect to the potential for adverse rate impacts on customers who are not participants in DSM programs. The paper consists of an identification of the pros and cons of DSM as a competitive strategy, the tradeoff which can occur between the cost impacts and rate impacts of DSM, and an examination of alternative strategies for maximizing the utilization of DSM both as a resource and as a competitive strategy

    This paper will trace the evolution of Ontario Hydro's DSM programs from an alternative to supply side resources to a core function of the utility. Ontario Hydro is changing from an energy provider to an energy services company. Four years of ambitious DSM have been successful. A key element of Ontario Hydro's strategy is to create a fundamental cultural transformation in the way Ontarians think about energy and energy efficiency. The impacts on customers, the market place and Ontario Hydro have been significant. This paper will trace these impacts through a description of Ontario Hydro's evolving approach to demand-side management

    Economic development in the United States depends on a reliable and affordable power supply. The nation will need well educated engineers to design a modern, safe, secure, and reliable power grid for our future needs. An anticipated shortage of qualified engineers has caused considerable concern in many professional circles, and various steps are being taken nationwide to alleviate the potential shortage and ensure the North American power system's reliability, and our world-wide economic competitiveness. To help provide a well-educated and trained workforce which can sustain and modernize the nation's power grid, Gonzaga University's School of Engineering and Applied Science has established a five-course (15-credit hour) Certificate Program in Transmission and Distribution (T&D) Engineering. The program has been specifically designed to provide working utility engineering professionals with on-line access to advanced engineering courses which cover modern design practice with an industry-focused theoretical foundation. A total of twelve courses have been developed to-date and students may select any five in their area of interest for the T&D Certificate. As each course is developed and taught by a team of experienced engineers (from public and private utilities, consultants, and industry suppliers), students are provided a unique opportunity to interact directly with different industry experts over the eight weeks of each course. Course material incorporates advanced aspects of civil, electrical, and mechanical engineering disciplines that apply to power system design and are appropriate for graduate engineers. As such, target students for the certificate program include: (1) recent graduates with a Bachelor of Science Degree in an engineering field (civil, mechanical, electrical, etc.); (2) senior engineers moving from other fields to the utility industry (i.e. paper industry to utility engineering or project management positions); and (3) regular

  6. Handbook of evaluation of utility DSM programs

    Program evaluation has become a central issue in the world of utility integrated resource planning. The DSM programs that utilities were operating to meet federal requirements or to improve customer relations are now becoming big business. DSM is being considered an important resource in a utility`s portfolio of options. In the last five years, the amount of money that utilities have invested in DSM has grown exponentially in most regulatory jurisdictions. Market analysts are now talking about DSM being a $30 billion industry by the end of the decade. If the large volume of DSM-program investments was not enough to highlight the importance of evaluation, then the introduction of regulatory incentives has really focused the spotlight. This handbook was developed through a process that involved many of those people who represent the diverse constituencies of DSM-program evaluation. We have come to recognize the many technical disciplines that must be employed to evaluate DSM programs. An analysis might start out based on the principles of utility load research to find out what happened, but a combination of engineering and statistical methods must be used to ``triangulate`` an estimate of what would have happened without the program. The difference, of course, is that elusive but prized result of evaluation: what happened as the direct result of the DSM program. Technical performance of DSM measures is not the sole determinant of the answer, either. We also recognize the importance of such behavioral attributes of DSM as persistence and free ridership. Finally, DSM evaluation is meaningless without attention to planning an approach, communicating results to relevant decision-makers, and focusing as much on the process as the impacts of the program. These topics are all covered in this handbook.

  7. User's guide to SERICPAC: A computer program for calculating electric-utility avoided costs rates

    1982-05-01

    SERICPAC is a computer program developed to calculate average avoided cost rates for decentralized power producers and cogenerators that sell electricity to electric utilities. SERICPAC works in tandem with SERICOST, a program to calculate avoided costs, and determines the appropriate rates for buying and selling of electricity from electric utilities to qualifying facilities (QF) as stipulated under Section 210 of PURA. SERICPAC contains simulation models for eight technologies including wind, hydro, biogas, and cogeneration. The simulations are converted in a diversified utility production which can be either gross production or net production, which accounts for an internal electricity usage by the QF. The program allows for adjustments to the production to be made for scheduled and forced outages. The final output of the model is a technology-specific average annual rate. The report contains a description of the technologies and the simulations as well as complete user's guide to SERICPAC.

  8. Utility DSM Programs from 1989 Through 1998: Continuation or Cross-Roads?

    1995-01-01

    Over the past five years, the Energy Information Administration (EIA) has been collecting data annually from US electric utilities on their demand-side management (DSM) programs, both current and projected. The latest data cover activities for 1993 and projections for 1994 and 1998. In 1993, 991 utilities operated DSM programs. That year, they spent $2.8 billion, a 13% increase over 1992 expenditures. These and earlier DSM programs saved 44,000 GWh of energy and reduced potential peak demand by 40,000 MW, 30% and 22% increases over the 1992 values, respectively. While some people predict the demise of electric-utility DSM programs, the data do not paint so bleak a picture. In most parts of the country, DSM programs grew in 1993 and utilities (as of Spring 1994) projected continued growth through 1998. Expenditures grew from 1.3% of revenues in 1992 to 1.5% in 1993, and are expected to grow 2.5% per year faster than inflation, which is equivalent to revenue growth. Thus, DSM spending is expected to stay constant at 1.5% of revenues through 1998. Because of the cumulative effect of DSM programs, energy savings are expected to grow from 1.2% of sales in 1992 to 1.6% in 1993 and 3.0% in 1998. Potential-peak reductions are expected to increase from 5.9% of peak demand in 1992 to 6.8% in 1993 and 8.9% in 1998. However, the growth in spending is not as rapid as the 8% annual real growth projected a year earlier. Actual expenditures in 1993 were 6.5% lower than projected early that year. Energy savings, on the other hand, were the same as projected earlier. Potential peak reductions were actually 9% higher than previously projected.

    The NWPA does provide guidance for a reasonable waste management program and one must work to implement it in an efficient and effective manner. It is well recognized that the lack of stability and predictability has been the bane of many nuclear reactor projects. The electric utilities are not satisfied with the progress of the nuclear waste program even though much has been achieved. DOE must continue in its struggle to seek a better balance between the technical, political and institutional aspects of the program to provide reasonable assurance that it will fulfill its contractual obligation with utilities

  10. Electric utility load management: rational use of energy program pilot study

    Energy Technology Data Exchange (ETDEWEB)

    1977-08-01

    In recognition of the role that load management can play in ensuring that the growing demand for electricity is met in a cost- and energy-efficient manner, in mid-1974, the NATO Committee on the Challenges of Modern Society sponsored all three meetings to provide a forum for representatives of U.S. and European utilities to exchange views and experiences on the various aspects of load management. It was the consensus of representatives at the meetings that three overall approaches offer significant opportunities for achieving improved load management: development of marginal-cost rate structures; power pooling and energy storage by utilities; and efforts by consumers. Industrial consumers can assist electric utilities in their efforts to level system loads through three important methods: interruptible power and deferred load control; peak self-generation; and shifts in operating schedules. Residential/commercial consumers also have an important role to play by managing both their electric heating load (through the interruption of direct-resistance heating and the storage of heat) and their air conditioning load. In response to the interest expressed by the participants in the CCMS conferences, the U.S. and several European governments, national electric utility industry organizations, state public utility commissions, and many individual utilities have undertaken R and D projects to investigate and test various aspects of these three approaches to load management. This report describes the projects that were presented by the utility representatives.

    Marketing research is increasing in importance as utilities become more marketing oriented. Marketing research managers need to maintain autonomy from the marketing director or ad agency and make sure their work is relevant to the utility's operation. This article will outline a model marketing research program for an electric utility. While a utility may not conduct each and every type of research described, the programs presented offer a smorgasbord of activities which successful electric utility marketers often use or have access to

    A good quality assurance program at a coal mine or power plant should be timely and consistent. The quality analysis is accurate due to a complete sampling of the coal stream loaded into the unit train. The sample analysis is accurate because standardized testing procedures are applied. A good coal quality assurance program includes: coal quality analysis of the delivered coal; bias testing of mechanical coal samplers; dust control during coal handling; and freeze conditioning during the winter. 2 figs., 2 plates

    The challenges and special issues which arise through the sale of a municipal electric utility were discussed. The recent sales of two utilities, the Kentville Electric Commission in Nova Scotia and Cornwall Electric in Ontario, were used as examples to show how the sale of an electric utility differs from the sale of most business enterprises. Municipal utilities are integral parts of the communities they serve which introduces several complexities into the sale. Factors that require special attention in the sale of the utilities, including electricity rates, local accountability, treatment of employees and local economic development, and the need for a comprehensive communication program to deal with the substantial public interest that sale of a municipal utility will engender, were reviewed

  18. DSM pocket guidebook

    Energy Technology Data Exchange (ETDEWEB)

    1991-04-01

    It has been estimated that if electricity were used more efficiently with commercially available end-use technologies, 24%--44% of the nation's current demand for electricity could be eliminated. Almost all major electric utilities in the west are investigating such demand-side management (DSM) opportunities. In some service territories, for example, improved efficiency could soon produce as much power as that from new coal-fired plants and produce it at a lower cost. Even utilities that currently have excess capacity are finding that DSM offers an opportunity to build efficient end-use stock to help them meet their future load shape objectives. Utility DSM programs typically consist of several measures designed to modify the utility's load shape (for example, innovative rate structures, direct utility control of loads, promotion of energy-efficient technologies, and customer education). The coordinated implementation of such measures requires planning, analysis of options, engineering, marketing, monitoring, and other coordination activities. This guidebook addresses one facet of an overall DSM program: selection of end-use technologies within the electrical utilities. This guidebook is intended to be a quick reference source both for utility field representatives in their customer interactions and for utility planners in the early stages of developing a DSM program. Finally, this guidebook is directed primarily at small municipal utilities and rural electric cooperatives within the Western Area Power Administration (Western) service area.

    The work documented in this report was undertaken as part of an ongoing investigation of innovative and potentially attractive value propositions for electricity storage by the United States Department of Energy (DOE) and Sandia National Laboratories (SNL) Electricity Storage Systems (ESS) Program. This study characterizes one especially attractive value proposition for modular electricity storage (MES): electric utility transmission and distribution (T&D) upgrade deferral. The T&D deferral benefit is characterized in detail. Also presented is a generalized framework for estimating the benefit. Other important and complementary (to T&D deferral) elements of possible value propositions involving MES are also characterized.

  20. An Assessment Model for Energy Efficiency Program Planning in Electric Utilities: Case of the Pacific of Northwest U.S.A

    Science.gov (United States)

    Iskin, Ibrahim

    Energy efficiency stands out with its potential to address a number of challenges that today's electric utilities face, including increasing and changing electricity demand, shrinking operating capacity, and decreasing system reliability and flexibility. Being the least cost and least risky alternative, the share of energy efficiency programs in utilities' energy portfolios has been on the rise since the 1980s, and their increasing importance is expected to continue in the future. Despite holding great promise, the ability to determine and invest in only the most promising program alternatives plays a key role in the successful use of energy efficiency as a utility-wide resource. This issue becomes even more significant considering the availability of a vast number of potential energy efficiency programs, the rapidly changing business environment, and the existence of multiple stakeholders. This dissertation introduces hierarchical decision modeling as the framework for energy efficiency program planning in electric utilities. The model focuses on the assessment of emerging energy efficiency programs and proposes to bridge the gap between technology screening and cost/benefit evaluation practices. This approach is expected to identify emerging technology alternatives which have the highest potential to pass cost/benefit ratio testing procedures and contribute to the effectiveness of decision practices in energy efficiency program planning. The model also incorporates rank order analysis and sensitivity analysis for testing the robustness of results from different stakeholder perspectives and future uncertainties in an attempt to enable more informed decision-making practices. The model was applied to the case of 13 high priority emerging energy efficiency program alternatives identified in the Pacific Northwest, U.S.A. The results of this study reveal that energy savings potential is the most important program management consideration in selecting emerging energy

    The US Electric Utility Demand-Side Management report is prepared by the Coal and Electric Data and Renewables Division; Office of Coal, Nuclear, Electric and Alternative Fuels; Energy Information Administration (EIA); US Department of Energy. The report presents comprehensive information on electric power industry demand-side management (DSM) activities in the US at the national, regional, and utility levels. The objective of the publication is to provide industry decision makers, government policy makers, analysts, and the general public with historical data that may be used in understanding DSM as it relates to the US electric power industry. The first chapter, ''Profile: US Electric Utility Demand-Side Management'', presents a general discussion of DSM, its history, current issues, and a review of key statistics for the year. Subsequent chapters present discussions and more detailed data on energy savings, peak load reductions and costs attributable to DSM. 9 figs., 24 tabs

  3. An analysis of the factors influencing demand-side management activity in the electric utility industry

    Science.gov (United States)

    Bock, Mark Joseph

    Demand-side management (DSM), defined as the "planning, implementation, and monitoring of utility activities designed to encourage consumers to modify their pattern of electricity usage, including the timing and level of electricity demand," is a relatively new concept in the U.S. electric power industry. Nevertheless, in twenty years since it was first introduced, utility expenditures on DSM programs, as well as the number of such programs, have grown rapidly. At first glance, it may seem peculiar that a firm would actively attempt to reduce demand for its primary product. There are two primary explanations as to why a utility might pursue DSM: regulatory mandate, and self-interest. The purpose of this dissertation is to determine the impact these influences have on the amount of DSM undertaken by utilities. This research is important for two reasons. First, it provides insight into whether DSM will continue to exist as competition becomes more prevalent in the industry. Secondly, it is important because no one has taken a comprehensive look at firm-level DSM activity on an industry-wide basis. The primary data set used in this dissertation is the U.S. Department of Energy's Annual Electric Utility Report, Form EIA-861, which represents the most comprehensive data set available for analyzing DSM activity in the U.S. There are four measures of DSM activity in this data set: (1) utility expenditures on DSM programs; (2) energy savings by DSM program participants; and (3) the actual and (4) the potential reductions in peak load resulting from utility DSM measures. Each is used as the dependent variable in an econometric analysis where independent variables include various utility characteristics, regulatory characteristics, and service territory and customer characteristics. In general, the results from the econometric analysis suggest that in 1993, DSM activity was primarily the result of regulatory pressure. All of the evidence suggests that if DSM continues to

    The possible impact of Federal nuclear waste legislation on electric utilities is discussed. The proposed legislation will set forth a well defined program enabling utilities with nuclear plants to make long term plans under a statutory mandate committed to an available technology and implementation timetable.

    Integrated demand-side management (IDSM) is a strategic approach to designing and delivering a portfolio of demand side management (DSM) programs to customers. IDSM typically delivers customer centric strategies with the goal of increasing the amount of DSM in the field, but doing so in a way that integrates various measures and technologies to improve their collective performance and/or penetration. Specifically, IDSM can be defined as the integrated or coordinated delivery of three or more of: (1) energy efficiency (EE), (2) demand response (DR), (3) distributed generation (DG), (4) storage, (5) electric vehicle (EV) technologies, and (6) time-based rate programs to residential and commercial electric utility customers. The electric industry’s limited experience deploying IDSM to date suggests that significant barriers may exist. A Berkeley Lab report “Barriers and Opportunities to Broader Adoption of Integrated Demand Side Management at Electric Utilities: A Scoping Study” explores recent electric utility experience with IDSM to provide an assessment of the barriers and potential benefits perceived or experienced by program administrators in their attempts to implement integrated programs. The research draws on surveys and interviews with eleven staff from a sample of eight DSM program administrators and program implementers who were currently implementing or had previously attempted to implement an IDSM program or initiative. Respondents provided their perspectives on drivers for IDSM and barriers to broader deployment. They also reported on actions they had undertaken to promote expanded delivery of IDSM and provided their assessments of the most important under-tapped opportunities for expanding IDSM efforts, both for program administrator and regulatory organizations.

    A series of overhead viewgraphs accompanied this presentation which focused on what municipalities should and can do to prepare for a competitive energy market in Ontario. Particular attention was given to business strategies, restructuring and transformation of the Municipal Electric Utilities (MEU). Issues and questions regarding ownership were also discussed. Each municipality will have to decide what is the most appropriate governance and organizational structure for their MEU. It was noted that one of the most contentious areas is refinancing and rate structures. Issues regarding merger or partnering options were also discussed. 1 tab

  8. Assessment of net lost revenue adjustment mechanisms for utility DSM programs

    1995-01-01

    Utility shareholders can lose money on demand-side management (DSM) investments between rate cases. Several industry analysts argue that the revenues lost from utility DSM programs are an important financial disincentive to utility DSM investment. A key utility regulatory reform undertaken since 1989 allows utilities to recover the lost revenues incurred through successful operation of DSM programs. Explicitly defined net lost revenue adjustment (NLRA) mechanisms are states` preferred approach to lost revenue recovery from DSM programs. This report examines the experiences states and utilities are having with the NLRA approach. The report has three objectives. First, we determine whether NLRA is a feasible and successful approach to removing the lost-revenue disincentive to utility operation of DSM programs. Second, we identify the conditions linked to successful implementation of NLRA mechanisms in different states and assess whether NLRA has changed utility investment behavior. Third, we suggest improvements to NLRA mechanisms. We first identify states with NLRA mechanisms where utilities are recovering lost revenues from DSM programs. We interview staff at regulatory agencies in all these states and utility staff in four states. These interviews focus on the status of NLRA, implementation issues, DSM measurement issues, and NLRA results. We also analyze regulatory agency orders on NLRA, as well as associated testimony, reports, and utility lost revenue recovery filings. Finally, we use qualitative and quantitative indicators to assess NLRA`s effectiveness. Contrary to the concerns raised by some industry analysts, our results indicate NLRA is a feasible approach to the lost-revenue disincentive.

    An end use model used in the United States who is advanced in demand-side management (DSM) was used to discuss possibilities of designing and evaluating Japan`s future DSM measures. The end use model assumes energy demand based on such factors as device characteristics, meteorological data, energy prices, user characteristics, market characteristics and DSM measures. The model calculates energy demand amount by end uses basically by multiplying assumptions on device unit requirement, device retention rate, and number of users. A representative tool as an end use model that handles load shapes is the hourly electric load model (HELM). It assumes an annual load curve and predicts a maximum system load. The present discussions have performed estimation on demand for consumer use air conditioners in a day in which a maximum summer load occurs in a reference year, estimation on load in a maximum load day in an estimated year, and estimation on weather sensitivity of loads. 5 refs., 5 figs.

    We examine the experiences that states and utilities are having with the NLRA approach. Contrary to concerns raised by some industry analysts, our results indicate the NLRA is a feasible approach to the lost-revenue disincentive. Seven of the 10 states we studied report no substantial problems with their approach. We observe several conditions linked to effective NLRA implementation and, for those states reporting problems, conditions linked to implementation difficulties. Finally, observed changes in utility-investment behavior occur after implementation of DSM rate reforms, which include deployment of NLRA mechanisms. We find that utilities in states with lost revenue recovery invest more than twice as much in DSM as do utilities in other states. (Author)

    The Public Utilities Regulatory Policies Act (PURPA) of 1979 requires that electrical utilities interconnect with qualifying facilities and purchase electricity at a rate based upon their full avoided costs (i.e., costs of providing both capacity and energy). Qualifying facilities (QF) include solar or geothermal electric units, hydropower, municipal solid waste or biomass-fired power plants, and cogeneration projects that satisfy maximum size, fuel use, ownership, location, and/or efficiency criteria. In Washington State, neither standard power purchase prices based upon a proxy ''avoided plant'', standard contracts, or a standard offer process have been used. Instead, a variety of power purchase contracts have been negotiated by developers of qualifying facilities with investor-owned utilities, public utility districts, and municipally-owned and operated utilities. With a hydro-based system, benefits associated with resource acquisition are determined in large part by how compatible the resource is with a utility's existing generation mix. Power purchase rates are negotiated and vary according to firm energy production, guarantees, ability to schedule maintenance or downtime, rights of refusal, power plant purchase options, project start date and length of contract; front-loading or levelization provisions; and the ability of the project to provide ''demonstrated'' capacity. Legislation was also enacted which allows PURPA to work effectively. Initial laws established ownership rights and provided irrigation districts, PUDs, and municipalities with expanded enabling powers. Financial processes were streamlined and, in some cases, simplified. Finally, laws were passed which are designed to ensure that development proceeds in an environmentally acceptable manner. In retrospect, PURPA has worked well within Washington. In the state of Washington, 20 small-scale hydroelectric projects with a combined generating capacity of

    The tax laws have greatly diminished the importance of utility preferred stock. But with utility construction programs expected to rise, it is an opportune time to see if preferreds can be an attractive option again. As recently as 1980, preferred stock financing by electric utilities comprised 55% of all U.S. corporate preferred stock issued. By 1989, this percentage had declined to under 12%. In dollar amounts, electric utility preferred stock financing had decreased by two-thirds over the same time period. The author analyzes just why this decline occurred and what it portends for the future

  14. Low-income DSM Programs: Methodological approach to determining the cost-effectiveness of coordinated partnerships

    1994-05-01

    As governments at all levels become increasingly budget-conscious, expenditures on low-income, demand-side management (DSM) programs are being evaluated more on the basis of efficiency at the expense of equity considerations. Budgetary pressures have also caused government agencies to emphasize resource leveraging and coordination with electric and gas utilities as a means of sharing the expenses of low-income programs. The increased involvement of electric and gas utilities in coordinated low-income DSM programs, in turn, has resulted in greater emphasis on estimating program cost-effectiveness. The objective of this study is to develop a methodological approach to estimate the cost- effectiveness of coordinated low-income DSM programs, given the special features that distinguish these programs from other utility-operated DSM programs. The general approach used in this study was to (1) select six coordinated low-income DSM programs from among those currently operating across the United States, (2) examine the main features of these programs, and (3) determine the conceptual and pragmatic problems associated with estimating their cost-effectiveness. Three types of coordination between government and utility cosponsors were identified. At one extreme, local agencies operate {open_quotes}parallel{close_quotes} programs, each of which is fully funded by a single sponsor (e.g., one funded by the U.S. Department of Energy and the other by a utility). At the other extreme are highly {open_quotes}coupled{close_quotes} programs that capitalize on the unique capabilities and resources offered by each cosponsor. In these programs, agencies employ a combination of utility and government funds to deliver weatherization services as part of an integrated effort. In between are {open_quotes}supplemental{close_quotes} programs that utilize resources to supplement the agency`s government-funded weatherization, with no changes to the operation of that program.

    Japanese electric demand has been steadily increasing in accordance with the economic growth. However, Japanese electric utilities are facing several problems; increasing construction cost of power facilities, siting constraints and the environmental issue of greenhouse gas emissions. To overcome these problems, electric utilities have been promoting demand-side-management (DSM) activities as well as supplier-side measures, with some presently being carried out through promoting energy conservation technologies and introducing electric tariff options of specific contracts for residential/commercial and industrial consumers. Japanese electric utilities have been carrying out R and D for the future, in particular, energy storage and heat storage which contribute to the improvement of load factor. In this paper, I would like to outline the R and D options for DSM in Japan. (author)

    Coordinated demand-side management (DSM) programs, co-administered by government agencies and electric and gas utilities, are likely to grow in importance in the coming years. Because of the unique features of these types of DSM programs, special care must be taken in assessing their cost-effectiveness. In this paper, we discuss these features, suggest how standard cost-effectiveness measures must be adapted to accommodate them, and show how important these adaptations are in assessing the cost-effectiveness of coordinated programs. At first, we use a least-cost, financial approach. The discussion indicates that failure to account properly for the special features of coordinated programs materially affects estimates of cost-effectiveness and, in extreme cases, may lead to rejection of otherwise cost-effective programs. Then extending the analysis to include economic factors, we speculate that most types of coordinated programs are more attractive than when evaluated on a financial basis. (author)

    This paper reports that electricity has become essential to American life. Approximately 70 percent of the nation's electricity is produced by burning fossil fuels, with coal, the most abundant, domestically-available, extracted natural resource, providing over 55 percent of the total electricity consumed. Emissions resulting from the burning of fossil fuels are regulated by both the federal and state governments. In 1970, Congress passed the comprehensive Clean Air Act which established a national program to protect the nation's air quality. In 1977, additional strict regulations were passed, which mandated even more stringent emission controls for factories, power plants and auto emissions. Prior to passage of the Clean Air Act of 1990, utilities were required to adhere to three major types of clean air regulations: National Ambient Air Quality Standards (NAAQS), New Source Performance Standards (NSPS), and Prevention of Significant Deterioration (PSD) review. NAAQS established limits for the maximum concentration levels of specific air pollutants in the ambient atmosphere. For example, for an area to be in compliance with the NAAQS for sulfur dioxide (SO 2 ), its annual average SO 2 concentration must not exceed 0.03 ppm of SO 2 and a peak 24 hour level of 0.14 ppm of SO 2 must not be exceeded more than once per year

    More and more US utilities are running more and larger demand-side management (DSM) programs. Assessing the cost-effectiveness of these programs raises difficult questions for utilities and their regulators. Should these programs aim to minimize the total cost of providing electric-energy services or should they minimize the price of electricity? This study offers quantitative estimates on the tradeoffs between total costs and electricity prices. This study uses a dynamic model to assess the effects of energy-efficiency programs on utility revenues, total resource costs, electricity prices, and electricity consumption for the period 1990 to 2010. These DSM programs are assessed under alternative scenarios. In these cases, fossil-fuel prices, load growth, the amount of excess capacity the utility has in 1990, planned retirements of power plants, the financial treatment of DSM programs, and the costs of energy- efficient programs vary. These analyses are conducted for three utilities: a ``base`` that is typical of US utilities; a ``surplus`` utility that has excess capacity, few planned retirements, and slow growth in fossil-fuel prices and incomes; and a ``deficit`` utility that has little excess capacity, many planned retirements, and rapid growth in fossil-fuel prices and incomes. 28 refs.

    1976-01-01

    The requirements of the electric utility industry as the primary potential market for geothermal energy are analyzed, based on a series of structured interviews with utility companies and financial institution executives. The interviews were designed to determine what information and technologies would be required before utilities would make investment decisions in favor of geothermal energy, the time frame in which the information and technologies would have to be available, and the influence of the governmental politics. The paper describes the geothermal resources, electric utility industry, its structure, the forces influencing utility companies, and their relationship to geothermal energy. A strategy for federal stimulation of utility investment in geothermal energy is suggested. Possibilities are discussed for stimulating utility investment through financial incentives, amelioration of institutional barriers, and technological improvements.

    On December 14, 1992, Cincinnati Gas ampersand Electric Company (CG ampersand E) and PSI Resources, Inc. announced an agreement to merge the two companies into a newly formed company, CINergy Corp. In announcing the proposed merger, James E. Rogers Jr., chairman, president, and chief executive officer of PSI said, Our companies have chosen to shape our future and our industry. This is an ideal partnership, since our strengths complement each other and our vision of the future is the same. Will this merger be the first of many that will shape the future of the electric utility in the United States? What is the vision of the future for the industry? About five years ago, a well-known Wall Street utility analyst traveled around the country talking about the anticipated consolidation of electric utility companies in the US His motto was Fifty in Five, meaning widespread consolidation that would reduce the number of independent investor-owned utilities from more than 100 to 50 within a five-year period. He even developed a map showing the mergers/consolidations he looked for and actually named names. More than five years have passed, and only a handful of utility mergers have taken place. But, looking forward from 1992, restructuring of the utility industry is very much a vision of the future. What is the driving force? The National Energy Policy Act of 1992 provides the legislative framework for the electric utility industry in the US in future years. While the specific rules that will govern the industry are yet to be promulgated, the intent to allow (even promote) competition is evident in the Act itself. But it appears the vision of the future is market driven

    This article presents the performance of electric utilities financially and in the stock market. The performance of the utility stocks compared with industrial stocks and long term government bonds is addressed as well as an analysis of the reasons for the differences. The effect of rate increases granted versus the rate of inflation on per share earnings is examined. A concern was expressed that increases in demand substantially larger than those projected by the industry for 1989 may result in excess capacity disappearing much sooner than predicted by industry managements

  8. How integrated resource planning for US electric utilities affects shareholder interests

    Hadley, S.; Hirst, E.

    1995-01-01

    Integrated resource planning (IRP) seeks to identify the mix of resources that can best meet the future energy-service needs of customers. These resources include new sources, types, and owners of power plants plus demand-side management (DSM) programs. However, little explicit attention is given to utility shareholders in the typical resource-planning proceeding. Because of the complexity of state regulatory practices and tax policies, it seems unlikely that different resources that provide comparable services to customers will yield comparable returns to shareholders. This study examines a typical US investor-owned utility's financial operations and performance using a spreadsheet model we developed for this project. The model simulates an electric utility's financial operations, and produces an annual income statement, balance sheet, and cash-flow statement. We calculated the net present value of realized (cash) return on equity as the primary factor used to represent shareholder interests. We examined shareholder returns for these resources as functions of public utility commission regulation, taxes, and the utility's operating environment. Given the increasingly competitive nature of electricity markets, we examined shareholder returns for these resources in an environment where the utility competes with other suppliers solely on the basis of electricity price.

    A review of activities in the electric power industry in Canada during 1998 is presented. In general, the principal preoccupation of Canadian electric utilities in 1998 was preparation for competition in a deregulated energy market. Utilities worked with provincial and national legislatures to redraw the rules of power supply. US FERC order 888 was central to many debates. FERC order 888 stipulates the unbundling of the retail aspects of operations from those that will remain regulated. Electric utilities also continued to prepare for the Y2K phenomenon and to work towards achieving ISO 14001 environmental management accreditation. They also explored alternative means of power generation. The year began with utilities across Canada sharing expertise and manpower to mitigate the impact of the ice storm which devastated parts of Quebec, Ontario and New Brunswick. It is believed that as a result of the ice storm of 1998, the Canadian utility industry is much better prepared to deal with weather-related emergencies than ever before. 1 fig

    The French law from February 10, 2000, about the modernization and development of the electric utility, has created new missions of public utility and foresees some compensation mechanisms for not handicapping the power operators in charge of these missions and for not creating competition distortions to their detriment on the European market. The author explains, first, the financial and economical stakes linked with these new missions. Then, he evokes the evolution of the energy context that has taken place between the 2. World war and the enforcement of the February 10, 2000 law, and he analyzes the systems foreseen for the power generation and distribution. For each public utility charge, the existing dispositions and those introduced by the law are analyzed and compared to the equivalent systems existing in other countries. Then, charge evaluation criteria and sharing rules and proposed. (J.S.)

    In 2006, Hydro-Quebec introduced a large DSM program on the market to promote the adoption of compact fluorescent lamps in Quebec households. After 3 years of program implementation, there was significant indication on the part of market actors that the promotional campaign component was quite effective in transforming the Quebec market. Hydro-Quebec therefore decided to modify its approach to program evaluation to include the quantification of market effects. Econoler led a team including American partners, Opinion Dynamics Inc. and Megdal and Associates to conduct an evaluation of program impacts on market transformation. An evaluation strategy was designed where different research tools would be integrated to determine market evolution over the two previous years. Each research method was used to determine an estimate of program impacts, then triangulated with other approaches to determine the most appropriate impact evaluation method regarding the Hydro-Quebec program. Research efforts included a non-participant survey, interviews at manufacturer headquarters across Canada, interviews with banner distributor representatives across Canada, the collection of sales and market share data from manufacturers and retailers as well as secondary research to identify other players that could influence the market. The evaluation revealed that savings of 168 GWh could be attributed to direct and indirect impacts of the program for the 2006-2007 period.

    Value-based benefits and costs of demand-side management (DSM) were discussed in the context of local electricity resource planning in downtown Toronto. The analysis considered the effects on local customer interruption as a result of DSM, and the deferment in need for local transmission and distribution upgrades. The life cycle and cash flow benefits and costs of DSM were discussed from the perspectives of the electric utility, the DSM-participating and non-participating customers, and society as a whole. Cashflow and lifecycle analyses results were reconciled. The Toronto Integrated Electrical Service (TIES) study, the basis for this paper, was described. Two main conclusions were reached, i.e. since the savings in the generationg system as a whole were far greater than the local savings,the value of a specific DSM program would be similar across a utility's service area, and (2) while cashflow analysis illustrated the short and medium term benefits and costs in a way most people intuitively understand, in effect,the lifecycle-cost estimates produce a clearer indicator of long-run economics

    Market transformation has emerged as a central policy objective for future publicly-funded energy-efficiency programs in California. California Public Utilities Commission (CPUC) Decision 95-12-063 calls for public funding to shift to activities designed to transform the energy-efficiency market. The CPUC envisions that funding {open_quotes}would only be needed for specific and limited periods of time to cause the market to be transformed{close_quotes}. At the same time, the CPUC also acknowledges that {open_quotes}there are many definitions of market transformation{close_quotes} ... and does {open_quotes}not attempt to refine those definitions today{close_quotes}. We argue that a definition of market transformation is essential. The literature is now replete with definitions, and an operational definition is needed for the CPUC to decide on which programs should be supported with public funds. The CPUC decision initially indicated a preference for programs that do not provide financial assistance 4-efficiency programs that rely on financial assistance to customers. However, energy customers have traditionally accounted for a substantial portion of California utility`s DSM programs, so the CPUC`s direction to use ratepayer funds to support programs that will transform the market raises critical questions about how to analyze what has happened in order to plan effectively for the future: Which utility energy-efficiency programs, including those that provide financial assistance to customers, have had market transforming effects? To what extent do current regulatory rules and practices encourage or discourage utilities from running programs that are designed to transform the market? Should the rules and programs be modified, and, if so, how, to promote market transformation?

  17. Turmoil and transition: Electric utility industry trends

    International Nuclear Information System (INIS)

    1994-06-01

    In a review of electric utility industry trends, focusing on North America, it is noted that four critical influences are dominant: competition in the electricity supply business; technological advances; the recognized need for environmental protection; and a favoring of market economics and customer choice. As energy costs rose in the 1970s and 1980s, electricity usage growth rates decreased and demand side management became an accepted alternative to building new power plants. In large areas of Canada and the USA, substantial surplus generation capacity arose, transmission linkages improved, and regional electricity markets developed. Privatization measures in the British electric sector were closely studied in North America and electric markets in the USA were pushed toward more competition with the 1992 Energy Policy Act. Non-utility generators have entered the market, including industrial companies, pipeline companies, independent renewable-energy providers, and power companies set up by the utilities themselves. Power pools may evolve into regional transmission grids in which the transmission owning utilities would exchange their lines for an interest in the grid. California is likely to lead in opening access to transmission on a regional scale. Distribution systems are likely to remain a regulated monopoly as before. Substantial change is expected in customer services as functions such as power purchase and conservation are being performed by independent companies. Other possible developments in the industry include emissions trading and spot markets for power. The implications of these trends for British Columbia Hydro are discussed

  18. Demand-controlling marketing of electric utilities

    Energy Technology Data Exchange (ETDEWEB)

    Raffee, H; Fritz, W

    1980-01-01

    In situations like the shortage of energy resources the particular autonomy of the users concerning energy demand raises more and more aggravating problems for the electric utilities (EU) and, last not least, for society (i.e. the peak-load problem, threatening bottlenecks in the supply situation). Thus the requirement for a demand-controlling marketing strategy of the EU with the help of which the individual demand should be influenced in the following manner is legitimate. The article discusses the targets, strategies, and instruments of marketing performed by the EU under the aspect of their efficiency concerning demand control. The discussion leads to e.g. the following results: that a marketing strategy for the sensible, responsible, and efficent use of energy, in the long-term, serves both the interests of the users and the interests of the EU; that such a marketing programme can have the required controlling effects especially with the help of strategies like market segmentation and cooperation. The discussion makes also clear that a demand-controlling marketing strategy of the EU can hardly be realized without a considerable change within the organization of the EU on one hand and, on the other, without expanding the marketing programme toward a marketing strategy of balance.

  2. Dealing with the paradox of energy efficiency promotion by electric utilities

    Sousa, José Luís; Martins, António Gomes; Jorge, Humberto

    Utility-based Demand-Side Management (DSM) programmes started after the oil crises of the 70's and were adopted by utilities as a standard practice. However, deregulation of the electricity industry threatened DSM. More recent concerns regarding energy dependence and environmental impact of energy use caused renewed attention on the utilities role in energy efficiency fostering. EE is presently a cross-cutting issue, influencing energy policy definition and regulatory activity worldwide. Some instruments for influencing the behaviour of electric utilities in the market are used by regulators, corresponding to both impositions and stimuli, such as defining savings targets or decoupling profits from energy sales. The paper addresses categories of regulatory instruments and refers to examples of countries and regions using these identified categories of instruments. Although some cases show voluntary involvement of utilities in EE promotion on the grounds of customer retention strategies, there is a clear prevalence of regulatory constrained markets where utilities rationally engage in energy efficiency promotion

    The implications of electric deregulation are and will continue to be pervasive and significant. Not only will the fundamental monopoly regulatory concepts of managing electric utilities change but deregulation will have a profound and dramatic impact on the way electric generating plants are managed and operated. In the past, under the various approaches to financial regulation, the economic benefits normally attributed to competition or that would have otherwise been derived from competitive or open market forces, were assumed to be embodied in and inherent to the various processes, methods and principles of financial oversight of utility companies by regional, state and municipal regulatory authorities. Traditionally, under the various forms of regulated monopolies, a utility company, in exchange for an exclusive franchise to produce and sell electricity in a particular region, was obligated to provide an adequate supply to all consumers wanting it, at a price that was 'just and reasonable'. The determination of adequate supply and reasonable price was a matter of interpretation by utility companies and their regulators. In essence, the ultimate economic benefits, normally attributed to price equilibrium, in balance with supply, demand and other market forces, were expected to be achieved through a complex, political process of financial regulatory oversight, in which utility companies were usually reimbursed for all annual expenses or their 'cost of service' and additionally allowed to earn a 'reasonable' rate of return on plant investments. The result was often escalating electric prices, over supplies of electric capacity, by justifying unnecessarily high reserve margins based on long planning horizons (typically 20 years or greater) with extrapolated demand requirements that were generally in excess of what actually occurred over time. Although the regulatory process varied from country or country and region-to-region, the fundamental principles, which

  8. Managing the GPS/GIS function in an electric utility

    International Nuclear Information System (INIS)

    Michelsen, M.W. Jr.

    1999-01-01

    A new period of higher significance has arrived for the GPS/GIS function at electric utilities such that to a degree never seen before, utility managers are looking to their GIS programs, filled with increasingly accurate data collected by GPS technology, before making many decisions. With this capability comes an expectation for GPS/GIS professionals to provide higher levels of planning and management of their data collection process. At Duke Power in Charlotte, North Carolina, managers rely on GPS mapping to fill their data collection equipment needs. When the city of Charlotte requested a more detailed billing system, Duke Power co-sponsored the street lighting inventory project, a comprehensive program implemented to fully account for street lighting facilities within the billing area. One of the key projects to be kept in mind was the creation of a common data base viewable by GIS from which a bill could be created and as well reveal data. A billing calculation routine can be run against the data base to generate a bill or use MapInfo to see a graphical picture. Prior to the creation of this data base capability, the difference between the data base as a display tool and billing system was a potential source of discrepancy, which is eliminated now. Creating the data base allows more than just creating a bill for the city, it allows Duke Power to work better with the city by improving its billing accountability and provides better service as well

    1990-01-01

    In 1989 Ontario Hydro implemented optional time-of-use (TOU) rates at the wholesale level for all municipal utilities in the province. At the same time, mandatory TOU rates were implemented for large users (customers with loads in excess of 5 MW) served by municipal utilities and Ontario Hydro's direct customers. To fully explore the potential of rate structures as demand-side management (DSM) tools, Ontario Hydro retained a consulting firm to carry out a survey of innovative rate structures in other jurisdications. The survey was intended to identify: the status quo of rate structures in other jurisdictions that were designed specifically to encourage DSM; a profile of the cost basis of the rate structures, for example whether traditional embedded cost of service analyses or contentious methods such as marginal cost pricing were used; whether innovative rates have been successful, and customer reactions and attitudes; and how innovative rates fit into the overall strategy of the utilities. It was found that TOU, interruptible and end-use targeted rates are the rate structures of choice for many utilities. Most are concerned with deferring capacity, reducing peak demand, and shifting load out of peak periods. Most utilities report success with their programs and satisfaction with the present form of the programs. 5 tabs

    1996-12-31

    US utility DSM programs have been a highly successful regulatory approach for overcoming shortcomings in the markets for energy services. The foundation for this unique partnership between governmental and utility interests can be traced first to the private-ownership structure of this vertically integrated industry and second to the monopoly franchises granted to it by U.S. state regulators. U.S. electricity industry restructuring calls into question both of these basic conditions, and thus the future of utility DSM programs. This paper describes the range and history of DSM programs offered by U.S. electric utilities, with a focus on the political, economic, and regulatory events that have shaped their evolution. For the future, we expect DSM programs to continue on two parallel paths reflecting both the changing business interests of electric utilities in a restructured industry as well as the continuing public interest in the environmental consequences of electricity generation.

  14. U.S. utilities' experiences with the implementation of energy efficiency programs

    Science.gov (United States)

    Goss, Courtney

    In the U.S., many electric utility companies are offering demand-side management (DSM) programs to their customers as ways to save money and energy. However, it is challenging to compare these programs between utility companies throughout the U.S. because of the variability of state energy policies. For example, some states in the U.S. have deregulated electricity markets and others do not. In addition, utility companies within a state differ depending on ownership and size. This study examines 12 utilities' experiences with DSM programs and compares the programs' annual energy savings results that the selected utilities reported to the Energy Information Administration (EIA). The 2009 EIA data suggests that DSM program effectiveness is not significantly affected by electricity market deregulation or utility ownership. However, DSM programs seem to generally be more effective when administered by utilities located in states with energy savings requirements and DSM program mandates.

The objective of the publication is to provide Federal and State governments, industry, and the general public with current and historical data that can be used for policymaking and decisionmaking purposes related to publicly owned electric utility issues. Generator and nongenerator summaries are presented in this publication. Four years of summary financial data are provided. Summaries of generators for fiscal years ending June 30 and December 31, nongenerators for fiscal years ending June 30 and December 31, and summaries of all respondents are provided. The composite tables present aggregates of income statement and balance sheet data, as well as financial indicators. Composite tables also display electric operation and maintenance expenses, electric utility plant, number of consumers, sales of electricity, and operating revenue, and electric energy account data. The primary source of publicly owned financial data is the Form EIA-412, {open_quotes}Annual Report of Public Electric Utilities.{close_quotes} Public electric utilities file this survey on a fiscal year, rather than a calendar year basis, in conformance with their recordkeeping practices. In previous editions of this publication, data were aggregated by the two most commonly reported fiscal years, June 30 and December 31. This omitted approximately 20 percent of the respondents who operate on fiscal years ending in other months. Accordingly, the EIA undertook a review of the Form EIA-412 submissions to determine if alternative classifications of publicly owned electric utilities would permit the inclusion of all respondents.

  16. Financial incentives for DSM [demand-side management]: Theory and practice

    International Nuclear Information System (INIS)

    Reid, M.W.

    1990-01-01

    Recent efforts to provide incentives for electric utilities in the USA to undertake demand-side management (DSM) programs are reviewed. The major need for incentives is seen as the overcoming of disincentives inherent in traditional regulation that affect utilities' interest in, and motivation for, DSM programs. These disincentives include the failure to recover all program costs, loss of revenues, and loss of financial opportunity. In addition, utilities seldom perceive DSM as a low-risk proposition; principal areas of concern include regulatory risk, competitive risk, and balance sheet risk. In view of these disincentives and risks, any DSM program therefore should provide for full and timely recovery of all program costs; adjust for DSM-induced revenue losses; and counterbalance risk and loss of financial opportunity by providing a bonus above cost. Three utility-specific incentive proposals are presented for the case of utilities in New York, Massachusetts, and Pennsylvania. Each of these programs meets the goal of overcoming the disincentives that surround utility DSM programs. The most significant differences across the mechanisms are found in the bonus component. Mechanisms that reduce the utility's uncertainty about the receipt of a bonus by providing it in a lump sum will likely prove more powerful motivators than those that spread the bonus out over a period of years. Use of preapproved per-unit or per-customer impact measurements reduces uncertainty and thus increases the apparent value of the bonus. Annual review of program plans and assumed impacts, supported by continuing evaluation activities, minimizes the risk that the utilities will gamble with the system or receive excessive awards. 6 refs

    This report offers perspectives on the future of the electric utility industry. These perspectives will be used in further research to assess the prospects for Integrated Resource Planning (IRP). The perspectives are developed first by examining economic, political and regulatory, societal, technological, and environmental trends that are (1) national and global in scope and (2) directly related to the electric utility industry. Major national and global trends include increasing global economic competition, increasing political and ethnic strife, rapidly changing technologies, and increasing worldwide concern about the environment. Major trends in the utility industry include increasing competition in generation; changing patterns of electricity demand; increasing use of information technology to control power systems; and increasing implementation of environmental controls. Ways in which the national and global trends may directly affect the utility industry are also explored. The trends are used to construct three global and national scenarios- ``business as usual,`` ``technotopia future,`` and ``fortress state`` -and three electric utility scenarios- ``frozen in headlights,`` ``megaelectric,`` and ``discomania.`` The scenarios are designed to be thought provoking descriptions of potential futures, not predictions of the future, although three key variables are identified that will have significant impacts on which future evolves-global climate change, utility technologies, and competition. While emphasis needs to be placed on understanding the electric utility scenarios, the interactions between the two sets of scenarios is also of interest.

    Superconducting inductors provide a compact and efficient means of storing electrical energy without an intermediate conversion process. Energy storage inductors are under development for load leveling and transmission line stabilization in electric utility systems and for driving magnetic confinement and plasma heating coils in fusion energy systems. Fluctuating electric power demands force the electric utility industry to have more installed generating capacity than the average load requires. Energy storage can increase the utilization of base-load fossil and nuclear power plants for electric utilities. The Los Alamos Scientific Laboratory and the University of Wisconsin are developing superconducting magnetic energy storage (SMES) systems, which will store and deliver electrical energy for load leveling, peak shaving, and the stabilization of electric utility networks. In the fusion area, inductive energy transfer and storage is being developed. Both 1-ms fast-discharge theta-pinch systems and 1-to-2-s slow energy transfer tokamak systems have been demonstrated. The major components and the method of operation of a SMES unit are described, and potential applications of different size SMES systems in electric power grids are presented. Results are given of a reference design for a 10-GWh unit for load leveling, of a 30-MJ coil proposed for system stabilization, and of tests with a small-scale, 100-kJ magnetic energy storage system. The results of the fusion energy storage and transfer tests are presented. The common technology base for the various storage systems is discussed

  12. Strategic rigidity and foresight for technology adoption among electric utilities

    Shah, Arsalan Nisar; Palacios, Miguel; Ruiz, Felipe

    2013-01-01

    The variation in the adoption of a technology as a major source of competitive advantage has been attributed to the wide-ranging strategic foresight and the integrative capability of a firm. These possible areas of competitive advantage can exist in the periphery of the firm's strategic vision and can get easily blurred as a result of rigidness and can permeate in the decision-making process of the firm. This article explores how electric utility firms with a renewable energy portfolio can become strategically rigid in terms of adoption of newer technologies. The reluctance or delay in the adoption of new technology can be characterized as strategic rigidness, brought upon as a result of a firm's core competence or core capability in the other, more conventional technology arrangement. This paper explores the implications of such rigidness on the performance of a firm and consequently on the energy eco-system. The paper substantiates the results by emphasizing the case of Iberdrola S.A., an incumbent firm as a wind energy developer and its adoption decision behavior. We illustrate that the very routines that create competitive advantage for firms in the electric utility industry are vulnerable as they might also develop as sources of competitive disadvantage, when firms confront environmental change and uncertainty. - Highlights: • Present a firm-level perspective on technology adoption behavior among electric utilities. • Firms with mature technology can become rigid towards newer technologies. • Case study analysis of a major electric utility firm. • Implications of ‘technology rigidness’ on the energy eco-system

    Kansai Electric Power Co. and Mitsubishi Electric Co. have been developing the electric utility dispersed use PAFC stack operated under the ambient pressure. The new cell design have been developed, so that the large scale cell (1 m{sup 2} size) was adopted for the stack. To confirm the performance and the stability of the 1 m{sup 2} scale cell design, the short stack study had been performed.

    Since oil crisis, in 1973 and 1979, some electrical utilities in Brazil begun investments in alternative projects for example production of electrolytic hydrogen, peats with energetics goals, steam from electric boiler, and methanol from wood gasification. With oil substitution goals, these projects have not success actually, after attenuated the crisis. However, the results acquired is experience for the development of the brazilian energy patterns.

  17. Managing an evolution: Deregulation of the electric utility industry

    Energy Technology Data Exchange (ETDEWEB)

    Skinner, S.K.

    1994-12-31

    The author discusses the emerging competitive situation in the electric power industry as deregulation of electric utilities looms on the horizon. The paper supports this change, and the competition it will bring, but urges caution as changes are instituted, and the regulatory bodies decide how and how much to free, and at what rates. The reason for his urge for caution comes from historical experience of other industries, which were smaller and had less direct impact on every American.

  19. Cost and quality of fuels for electric utility plants 1991

    International Nuclear Information System (INIS)

    1992-01-01

    Data for 1991 and 1990 receipts and costs for fossil fuels discussed in the Executive Summary are displayed in Tables ES1 through ES7. These data are for electric generating plants with a total steam-electric and combined-cycle nameplate capacity of 50 or more megawatts. Data presented in the Executive Summary on generation, consumption, and stocks of fossil fuels at electric utilities are based on data collected on the Energy Information Administration, Form EIA-759, ''Monthly Power Plant Report.'' These data cover all electric generating plants. The average delivered cost of coal, petroleum, and gas each decreased in 1991 from 1990 levels. Overall, the average annual cost of fossil fuels delivered to electric utilities in 1991 was $1.60 per million Btu, a decrease of $0.09 per million Btu from 1990. This was the lowest average annual cost since 1978 and was the result of the abundant supply of coal, petroleum, and gas available to electric utilities. US net generation of electricity by all electric utilities in 1991 increased by less than I percent--the smallest increase since the decline that occurred in 1982.3 Coal and gas-fired steam net generation, each, decreased by less than I percent and petroleum-fired steam net generation by nearly 5 percent. Nuclear-powered net generation, however, increased by 6 percent. Fossil fuels accounted for 68 percent of all generation; nuclear, 22 percent; and hydroelectric, 10 percent. Sales of electricity to ultimate consumers in 1991 were 2 percent higher than during 1990

  20. Emission impacts of demand-side programs: What have we achieved so far and how will recent policy decision change program choices?

    Congress and many state legislatures have been discussing the possibility of regulating carbon dioxide (CO 2 ), Sulfur dioxide (SO 2 ), nitrogen oxides (NO x ), chlorofluorocarbons (CFC's) and other emissions. Key to these discussions is the recommendation that energy efficiency, and specifically electric utility demand-side management (DSM) programs, be used as an emission control option. Methods for incorporating the social or external costs of energy production into utility planning are being developed, and estimates of potential emission impacts attributed to DSM programs have been calculated. However, little research has calculated the actual emission impacts from existing DSM programs. The increasing need for electric energy services and fossil fuel generation create an apparent conflict with the risks and regulations associated with global climate change and clean air. Electric utility DSM programs can be used to resolve these conflicts by providing equal or better energy services and a net reduction in emissions. This paper summarizes three separate related research projects. The first study, Impacts of Electric Utility Demand-Side Management Programs on Power Plant Emissions, collects utility and state data on existing DSM programs to approximate the level of SO 2 , NO x , and CO 2 reductions on a regional and national basis. Phase 1 of this study is a completed survey of DSM savings by state. The second and third studies, Carbon Dioxide Reduction Through Electrification of the Industrial and Transportation Sectors, and Carbon Dioxide Reduction Through Electrification of the Residential and Commercial Sectors, compare selected high efficiency electric technologies with fossil-fueled alternatives to determine CO 2 emissions. Through these studies, the authors have begun to quantify the emissions impacts from utility DSM programs and efficient electric equipment

  1. Electric utilities and the demand for natural gas

    Energy Technology Data Exchange (ETDEWEB)

    Uri, N D; Atkinson, S

    1976-03-01

    The scarcity of natural gas has given rise to a series of priorities of deliveries based on end use and drafted by the Federal Power Commission. The U.S. Supreme Court, on June 7, 1972, held that the Commission has jurisdiction over curtailments in the service of gas in interstate commerce to both resale and direct industrial customers. This decision reversed a Fifth Circuit Court ruling that protected direct industrial customers from curtailments. The FPC priority curtailments are classed from 1 to 9, for which electric utilities are concentrated in classes 4 to 9. As weather conditions become more severe, not only do the residential and commercial consumers demand more electrical energy, they also demand more natural gas. The result is that there is less natural gas available for electric utilities to use for generation so they change to an alternative fuel. A demand model for the short term for natural gas for electric utilities is given; primary factors involve the price of natural gas, the prices of substitute fuels, and the demand for electrical energy by the various consumer classes.

    1997-01-01

    A recent survey of public opinion has shown that 85 per cent of the public view their electric utility company favourably. This represents a 10 per cent increase over last year. A survey of 4,090 Canadians was conducted which looked at the perceptions of the value of electricity services compared to telephone, natural gas, banking, and home insurance services. The study showed that Canadian electric utility companies are viewed as positively as the telephone companies and almost as favourably as the banks. Some 71 per cent of respondents reported that the value they receive from their electric utility is excellent or good. Lower prices, better customer services and increased research into alternative power sources were among the benefits that Canadians perceive would result from a more competitive electricity sector. Some misgivings about deregulation included a belief that there would be less attention to environmental concerns and more outages. Four per cent of the respondents said they would 'definitely' switch to an alternative supplier of electricity, while 25 per cent said they would 'probably' switch to an alternative supplier of electricity. 2 tabs

    This article examines the potential effect of demand side management (DSM) on the economics of the independent power industry. The topics of the article include the contribution of DSM to future resource needs, integrated resource planning, DSM incentives, DSM bidding, measuring DSM success, DSM as a part of future utility planning, and strategic responses to DSM

  4. Environmental benefits of DSM externalities and resource planning

    International Nuclear Information System (INIS)

    Tempchin, R.S.; Goldsmith, M.W.

    1991-01-01

    Recently, political and regulatory initiatives have prompted the expansion of demand-side management (DSM) programs as a means of realizing environmental and economic benefits for both consumers and electric utilities. The Edison Electric Institute sponsored two recent studies to examine the effectiveness of this effort. A national survey of DSM program activity was conducted to determine the resultant air emissions reductions. Due to pervasive inconsistencies in data measurement and reporting, coupled with the number and degree of assumptions necessary to quantify state-by-state energy savings, scientifically verifiable estimates of these emissions reductions could not be developed. The second study, a review of the development and application of monetized environmental externalities, found that the current state regulatory practice of assigned monetary values to the environmental impacts of resource options is based on imcomplete data and applied in an imbalanced manner. Due to the complexity of assessing the direct impact costs of power generation, shadow prices derived from cost conditions have been developed to assign a dollar value per pound of pollutant. These alternative measures of cost, which vary by as much as 300,000 percent from direct impact costs, are applied only to electricity. This singluar focus placed a potential financial disincentive on electricity use, precludes a balanced assessment of all potential fuel choices and excludes any valuation of the considerable environmental and economic benefits of electric technologies

  5. Tacit Knowledge Capture and the Brain-Drain at Electrical Utilities

    Science.gov (United States)

    Perjanik, Nicholas Steven

    As a consequence of an aging workforce, electric utilities are at risk of losing their most experienced and knowledgeable electrical engineers. In this research, the problem was a lack of understanding of what electric utilities were doing to capture the tacit knowledge or know-how of these engineers. The purpose of this qualitative research study was to explore the tacit knowledge capture strategies currently used in the industry by conducting a case study of 7 U.S. electrical utilities that have demonstrated an industry commitment to improving operational standards. The research question addressed the implemented strategies to capture the tacit knowledge of retiring electrical engineers and technical personnel. The research methodology involved a qualitative embedded case study. The theories used in this study included knowledge creation theory, resource-based theory, and organizational learning theory. Data were collected through one time interviews of a senior electrical engineer or technician within each utility and a workforce planning or training professional within 2 of the 7 utilities. The analysis included the use of triangulation and content analysis strategies. Ten tacit knowledge capture strategies were identified: (a) formal and informal on-boarding mentorship and apprenticeship programs, (b) formal and informal off-boarding mentorship programs, (c) formal and informal training programs, (d) using lessons learned during training sessions, (e) communities of practice, (f) technology enabled tools, (g) storytelling, (h) exit interviews, (i) rehiring of retirees as consultants, and (j) knowledge risk assessments. This research contributes to social change by offering strategies to capture the know-how needed to ensure operational continuity in the delivery of safe, reliable, and sustainable power.

  6. Positioning the electric utility to build information infrastructure

    Energy Technology Data Exchange (ETDEWEB)

    1994-11-01

    In two particular respects (briefly investigated in this study from a lawyer`s perspective), electric utilities appear uniquely well-positioned to contribute to the National Information Infrastructure (NII). First of all, utilities have legal powers derived from their charters and operating authorities, confirmed in their rights-of-way, to carry out activities and functions necessary for delivering electric service. These activities and functions include building telecommunications facilities and undertaking information services that have become essential to managing electricity demand and supply. The economic value of the efficiencies made possible by telecommunications and information could be substantial. How great remains to be established, but by many estimates electric utility applications could fund a significant share of the capital costs of building the NII. Though utilities` legal powers to pursue such efficiencies through telecommunications and information appear beyond dispute, it is likely that the effort to do so will produce substantial excess capacity. Who will benefit from this excess capacity is a potentially contentious political question that demands early resolution. Will this windfall go to the utility, the customer, or no one (because of political paralysis), or will there be some equitable and practical split? A second aspect of inquiry here points to another contemporary issue of very great societal importance that could very well become the platform on which the first question can be resolved fortuitously-how to achieve universal telecommunications service. In the effort to fashion the NII that will now continue, ways and means to maximize the unique potential contribution of electric utilities to meeting important social and economic needs--in particular, universal service--merit priority attention.

    1998-01-01

    The challenges that municipal electric utilities (MEUs) face in the new deregulated power market in North America were discussed. This presentation also highlighted the factors that affected the risk that companies in the U.S. Mid-West were exposed to in June 1998. During that time, MEUs had to deal with financial fallouts and price spikes as a result of very high temperatures, generation outages, and transmission line relief. The focus is on price risk and credit risk and how a strong risk management team can be instrumental in avoiding price spikes like those that occurred in June 1998

    2003-01-01

    Quantitative analysis of 47 US investor-owned electric utilities' environmental exposures to impending air quality and climate policies shows potentially material and highly differentiated financial impacts. For many companies the minimized compliance costs of a four-pollutant cap-and-trade regulatory regime would be less than those of a three-pollutant regime that omitted controls on carbon dioxide emissions. Fragmented regulatory requirements would have the highest compliance costs. The companies studied vary considerably in the adequacy of their financial reporting of these potential impacts. Greater transparency would benefit investors and the most favorably positioned companies. (author)

    Salies, Evens; Nesta, Lionel

    2010-10-01

    The authors report a study of the influence of reforms which introduce a liberalisation of energy markets on the innovation behaviour of electric utilities in some countries. Within a context of concentration of this sector, the hypothesis of a negative impact on patent registration by electric utilities is tested by the authors. They first define the notion of environmental innovation and its evolution in the electric energy sector as the climate and environment issues are nowadays extremely important for the energy sector. R and D here addresses micro-generation, fuel cells, tidal turbine systems, energy production by using solar energy, and biomass gasification. They discuss numbers of pattern registrations by European utilities before and after laws on energy market reform. They present an econometric model and data used to test the hypothesis and comment the obtained results. The model comprises a knowledge production function, and various explicative variables (firm size and R and D, reforms, technological opportunities, energy mix, and influence of demand)

  13. Consumer's Guide to the economics of electric-utility ratemaking

    Energy Technology Data Exchange (ETDEWEB)

    1980-05-01

    This guide deals primarily with the economics of electric utilities, although certain legal and organizational aspects of utilities are discussed. Each of the seven chapters addresses a particular facet of public-utility ratemaking. Chapter One contains a discussion of the evolution of the public-utility concept, as well as the legal and economic justification for public utilities. The second chapter sets forth an analytical economic model which provides the basis for the next four chapters. These chapters contain a detailed examination of total operating costs, the rate base, the rate of return, and the rate structure. The final chapter discusses a number of current issues regarding electric utilities, mainly factors related to fuel-adjustment costs, advertising, taxes, construction work in progress, and lifeline rates. Some of the examples used in the Guide are from particular states, such as Illinois and California. These examples are used to illustrate specific points. Consumers in other states can generalize them to their states and not change the meaning or significance of the points. 27 references, 8 tables.

  14. Challenges in sensor development for the electric utility industry

    Science.gov (United States)

    Ward, Barry H.

    1999-01-01

    The electric utility industry is reducing operating costs in order to prepare for deregulation. The reduction in operating cost has meant a reduction in manpower. The ability to utilize remaining maintenance staff more effectively and to stay competitive in a deregulated environment has therefore become critical. In recent years, the industry has moved away from routine or periodic maintenance to predictive or condition based maintenance. This requires the assessment of equipment condition by frequent testing and inspection; a requirement that is incompatible with cost reduction. To overcome this dilemma, industry trends are toward condition monitoring, whereby the health of apparatus is monitored continuously. This requires the installation of sensors hr transducers on power equipment and the data taken forwarded to an intelligent device for further processing. These devices then analyze the data and make evaluations based on parameter levels or trends, in an attempt to predict possible deterioration. This continuous monitoring allows the electric utility to schedule maintenance on an as needed basis. The industry has been faced with many challenges in sensor design. The measurement of physical, chemical and electrical parameters under extreme conditions of electric fields, magnetic fields, temperature, corrosion, etc. is extensive. This paper will give an overview of these challenges and the solutions adopted for apparatus such as power transformers, circuit breakers, boilers, cables, batteries, and rotating machinery.

  15. An analysis of electric utility embedded power supply costs

    International Nuclear Information System (INIS)

    Kahal, M.; Brown, D.

    1998-01-01

    There is little doubt that for the vast majority of electric utilities the embedded costs of power supply exceed market prices, giving rise to the stranded cost problem. Beyond that simple generalization, there are a number of crucial questions, which this study attempts to answer. What are the regional patterns of embedded cost differences? To what extent is the cost problem attributable to nuclear power? How does the cost of purchased power compare to the cost of utility self-generation? What is the breakdown of utility embedded generation costs between operating costs - which are potentially avoidable--and ownership costs, which by definition are ''sunk'' and therefore not avoidable? How will embedded generation costs and market prices compare over time? These are the crucial questions for states as they address retail-restructuring proposal. This study presents an analysis of generation costs, which addresses these key questions. A computerized costing model was developed and applied using FERC Form 1 data for 1995. The model analyzed embedded power supply costs (i.e.; self-generation plus purchased power) for two groups of investor-owned utilities, 49 non-nuclear vs. 63 nuclear. These two subsamples represent substantially the entire US investor-owned electric utility industry. For each utility, embedded cost is estimated both at busbar and at meter

    The implications of the MacDonald Committee's recommendations on introducing competition to Ontario's electricity industry were reviewed from the point of view of Toronto Hydro, the largest municipal utility and Ontario Hydro's largest customer. Issues examined included (1) the consequences of unbundling Ontario Hydro's generating, transmission and distribution functions, (2) the structural change option of phasing-in competition among Ontario Hydro and municipal and other private generators, (3) enhancing the efficiency of the distribution sector, and (4) the relative benefits and consequences of private equity as a means of enhancing competition through the sale of Ontario Hydro's generating assets, or the sale of non-essential business operations. Recommendations to the Committee included the need for the transmission grid to remain under public control, for electricity pricing to take into account the variable environmental impact of different generating types, and the need for transferring regulatory authority over municipal electric utilities from Ontario Hydro to the Ontario Energy Board

  17. Electric utility fuel choice behavior in the United States

    Energy Technology Data Exchange (ETDEWEB)

    Joskow, P.L.; Mishkin, F.S.

    1977-10-01

    Electric utility fuel choice behavior is analyzed by a conditional logit model to determine the effects of changing oil prices of five plants. Three of the plants faced favorable expected coal prices and, like many areas of the country, were insensitive to changing oil prices. This was not the case at the New England plant, however, where relatively small price increases would decrease the likelihood of choosing oil as an alternative fuel for new plants. The modeling of utility behavior in fuel decisions is felt to be applicable to other industries where a continuum of decision possibilities does not reasonably characterize choice alternatives. New behavior models are urged in order to obtain better predictions of the effects of a changing economic environment. 10 references.

  18. Citizen Advisory Council use in the electric utility industry

    International Nuclear Information System (INIS)

    McElfresh, R.W.

    1991-01-01

    Many electric utility companies have come to realize the Importance of seeking public input before launching corporate resources into major construction projects. One way to organize this input is to establish a Citizen Advisory Council (CAC). This paper describes the purpose of such a group, its advantages and limitations, and how it might be organized. This paper also describes the results of a survey of CAC use for facility siting purposes. Fifty large utility companies were contacted, eleven of which use CACs for siting purposes. Six of these were questioned in greater detail as to their success in using CACs on specific projects. All companies were positive about the use of CACs for public participation because the groups were able to bring valuable information to light and company credibility was enhanced. Most importantly, the responding companies believed they were able to save time in the siting and licensing process

  19. Energy economics: impacts on electric utilities' future decisions

    Smith, S.H.

    1983-01-01

    Despite financial and regulatory pressures that have led electric utilities to slow construction and minimize capital expenditures, Carolina Power and Light Company is proceeding with two new nuclear and two new coal facilities because it believes the commitment to expand must be made in the 1980s. The economic slowdown has given utilities a breathing period, but not enough to allow a complete stop in expansion if the utilities are to be ready for the expected economic growth of the 1990s. Financing this expansion is a slower process for regulated industries and leads to strained relations between customers and suppliers. The two can work together to promote conservation and load management, but higher rates must finance new construction to avoid a shortfall later. The costs of environmentally sound coal combustion and nuclear plant construction must both be reduced to help keep the recovery from being inflationary

    Schillo, B.; Shelby, M.; Ciliano, B.; Lang, C.; Stern, F.

    1991-01-01

    New environmental policies for the electric utility sector include some innovative compliance options. For example, the 1990 Clean Air Act Amendments include an emissions allowance trading system that allows affected sources to exchange sulfur dioxide emissions rights on an open market. One area being explored for innovative policy options is the Best Available Control Technology (BACT) specifications. Some have proposed an innovative interpretation of the BACT standard to achieve reductions in carbon emissions from utility sources. Under this proposal, any new power plant requesting an operating permit would be required to achieve the maximum level of cost-effective energy savings from DSM programs before an emissions permit would be issued. The level of cost-effective energy savings would be based on detailed analysis and DSM program evaluations, guided by other policy tools such as analysis using the Electric and Gas Utility Modeling System (EGUMS). This paper describes how EGUMS would be used to evaluate the proposed BACT standard policy and will include some preliminary results from this analysis. A general description of EGUMS is included as well as descriptions of how EGUMS is used for other national DSM policy analysis and for forecasting carbon emissions from the utility sector

    The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) contains criteria for psychiatric diagnoses that reflect advances in the science and conceptualization of mental disorders and address the needs of clinicians. DSM-5 also recommends research on dimensional measures of cross-cutting symptoms and diagnostic severity, which are expected to better capture patients' experiences with mental disorders. Prior to its May 2013 release, the American Psychiatric Association (APA) conducted field trials to examine the feasibility, clinical utility, reliability, and where possible, the validity of proposed DSM-5 diagnostic criteria and dimensional measures. The methods and measures proposed for the DSM-5 field trials were pilot tested in adult and child/adolescent clinical samples, with the goal to identify and correct design and procedural problems with the proposed methods before resources were expended for the larger DSM-5 Field Trials. Results allowed for the refinement of the protocols, procedures, and measures, which facilitated recruitment, implementation, and completion of the DSM-5 Field Trials. These results highlight the benefits of pilot studies in planning large multisite studies. Copyright © 2013, American Psychiatric Association. All rights reserved.

    1992-03-01

    A definitional mission evaluated the prospects of the US Trade and Development Program (TDP) funding a market demonstration of a Demand Side Management (DSM) program being developed by the Tenaga Nasional Berhad (TNB) in Malaysia. TNB is the national electric utility of Malaysia with the responsibility to promote economically efficient supply of electricity needed for the economic development of Peninsular Malaysia. DSM is a utility-financed program to affect energy savings at the enduse level thereby reducing peak and base loads. Historically, TNB has taken the peak load and the load duration curves as given in planning and implementing the least-cost generation expansion strategy. It has refrained from influencing the pattern of energy use by the customer through any means other than tariff structures and levels. The experience of many utilities with DSM in the U.S. offers TNB an opportunity to develop a suitable DSM program for Malaysia.

  3. Economic evaluations of fusion-based energy storage systems in an electric utility

    International Nuclear Information System (INIS)

    Hwang, W.G.

    1977-01-01

    The feasibility of introducing a fusion energy storage system, which consists of a fusion-fission reactor and a water-splitting process, in an electric utility was investigated. The fusion energy storage system was assumed to be run during off-peak periods in order to make use of unused, low fuel cost capacity of an electric utility. The fusion energy storage system produces both fissile fuel and hydrogen. The produced hydrogen was assumed to be transmitted through and stored in existing natural gas trunklines for later use during peak-load hours. The peaking units in the utility were assumed to burn the hydrogen. Reserve power is usually cheap on systems with heavy nuclear fission reactor installation. The system studied utilizes this cheap energy for producing expensive fuel. The thermochemical water-splitting process was employed to recover thermal energy from the fusion-fission reactor system. The cost of fusion energy storage systems as well as the value of produced fuel were calculated. In order to simulate the operations of the fusion energy storage system for a multi-year planning period, a computer program, FESUT (Fusion Energy Simulation at the University of Texas), was developed for the present study. Two year utility simulations with the fusion energy storage system were performed

  4. A comparison of hydrogen-fueled fuel cells and combustion engines for electric utility applications

    Schoenung, S.M.

    2000-01-01

    Hydrogen-fueled systems have been proposed for a number of stationary electric generation applications including remote power generation, load management, distribution system peak shaving, and reliability or power quality enhancement. Hydrogen fueling permits clean, low pollution operation. This is particularly true for systems that use hydrogen produced from electrolysis, rather than the reforming of hydrocarbon fuels. Both fuel cells and combustion engines are suitable technologies for using hydrogen in many electric utility applications. This paper presents results from several studies performed for the U.S. Department of Energy Hydrogen Program. A comparison between the two technologies shows that, whereas fuel cells are somewhat more energy efficient, combustion engine technology is less expensive. In this paper, a comparison of the two technologies is presented, with an emphasis on distributed power and power quality applications. The special case of a combined distributed generation I hydrogen refueling station is also addressed. The comparison is made on the basis of system costs and benefits, but also includes a comparison of technology status: power ratings and response time. A discussion of pollutant emissions and pollutant control strategies is included. The results show those electric utility applications for which each technology is best suited. (author)

    The Financial Statistics of Major US Investor-Owned Electric Utilities publication presents summary and detailed financial accounting data on the investor-owned electric utilities. The objective of the publication is to provide Federal and State governments, industry, and the general public with current and historical data that can be used for making policy and decisions relating to investor-owned electric utility issues. The US electric power industry is a combination of electric utilities (investor-owned, publicly owned, Federal, and cooperatives) and nonutility power producers. Investor-owned electric utilities account for over three-fourths of electric sales and revenue. Historically, the investor-owned electric utilities have served the large consolidated markets. There is substantial diversity among the investor-owned electric utilities in terms of services, size, fuel usage, and prices charged. Most investor-owned electric utilities generate, transmit, and distribute electric power. Investor-owned electric utilities operate in all States except Nebraska; Hawaii is the only State in which all electricity is supplied by investor-owned electric utilities. 5 figs., 57 tabs.

  6. Outsourcing decision factors in publicly owned electric utilities

    Gonzales, James Edward

    Purpose. The outsourcing of services in publicly owned electric utilities has generated some controversy. The purpose of this study was to explore this controversy by investigating the relationships between eight key independent variables and a dependent variable, "manager perceptions of overall value of outsourced services." The intent was to provide data so that utilities could make better decisions regarding outsourcing efforts. Theoretical framework. Decision theory was used as the framework for analyzing variables and alternatives used to support the outsourcing decision-making process. By reviewing these eight variables and the projected outputs and outcomes, a more predictive and potentially successful outsourcing effort can be realized. Methodology. A survey was distributed to a sample of 323 publicly owned electric utilities randomly selected from a population of 2,020 in the United States. Analysis of the data was made using statistical techniques including the Chi-Square, Lambda, Spearman's coefficient of rank correlation, as well as the Hypothesis Test, Rank Correlation, to test for relationships among the variables. Findings. Relationships among the eight key variables and perceptions of the overall value of outsourced services were generally weak. The notable exception was with the driving force (reason) for outsourcing decisions where the relationship was strongly positive. Conclusions and recommendations. The data in support of the research questions suggest that seven of the eight key variables may be weakly predictive of perceptions of the overall value of outsourced services. However, the primary driving force for outsourcing was strongly predictive. The data also suggest that many of the sampled utilities did not formally address these variables and alternatives, and therefore may not be achieving maximal results. Further studies utilizing customer perceptions rather than those of outsourcing service managers are recommended. In addition, it is

    This paper presents a framework for accessing comparative efficiencies of Indian State Owned Electric Utilities (SOEU), which have been mainly responsible for the generation, distribution and transmission of electricity in India. Performance of 26 utilities was evaluated using the non-parametric technique of Data Envelopment Analysis (DEA), and the impact of scale on the efficiency scores was also evaluated. The results indicate that the performance of several SOEUs is sub-optimal, suggesting the potential for significant cost reductions. Separate benchmarks were derived for possible reductions in employees' number, and the results indicate that several utilities deploy a much larger number of employees than that required by a best practice utility, and significant savings are possible on this account. It was also found that the bigger utilities display greater inefficiencies and have distinct scale inefficiencies. Exploiting scale efficiencies by suitable restructuring and unbundling of SOEUs are therefore crucial measures that may foster efficiencies in the SOEUs. The paper discusses these results in the context of related policy issues

  8. National Maglev initiative: California line electric utility power system requirements

    Science.gov (United States)

    Save, Phil

    1994-01-01

    The electrical utility power system requirements were determined for a Maglev line from San Diego to San Francisco and Sacramento with a maximum capacity of 12,000 passengers an hour in each direction at a speed of 300 miles per hour, or one train every 30 seconds in each direction. Basically the Maglev line requires one 50-MVA substation every 12.5 miles. The need for new power lines to serve these substations and their voltage levels are based not only on equipment loading criteria but also on limitations due to voltage flicker and harmonics created by the Maglev system. The resulting power system requirements and their costs depend mostly on the geographical area, urban or suburban with 'strong' power systems, or mountains and rural areas with 'weak' power systems. A reliability evaluation indicated that emergency power sources, such as a 10-MW battery at each substation, were not justified if sufficient redundancy is provided in the design of the substations and the power lines serving them. With a cost of $5.6 M per mile, the power system requirements, including the 12-kV DC cables and the inverters along the Maglev line, were found to be the second largest cost component of the Maglev system, after the cost of the guideway system ($9.1 M per mile), out of a total cost of $23 M per mile.

    The reduction of oxides of nitrogen emissions is becoming an increasingly important part of ozone attainment plans. As a part of its ozone attainment plan, the Ventura County (California) Air Pollution Control Board adopted in June, 1991, a regulation (Rule 59) to limit oxides of nitrogen emissions from four electrical utility boilers in the county. Rule development took two years and involved considerable public input. The emission limit for each of two 750 megawatt units is set at 0.10 pounds of NO x per megawatt-hour net after June, 1994. The emission limit for each of two 215 megawatt units is 0.20 pounds of NO x per megawatt-hour after June, 1996. Additional limitations are included for fuel oil operation. The rule does not specify an emission control technology. Conventional selective catalytic reduction, urea injection and combustion modifications are considered the technologies most likely to be used to comply. At $17,613 per ton of NO x reduced for the two large boilers and $8.992 per ton of NO x reduced for the small boilers, the rule is considered cost effective. The capital cost for conventional selective catalytic reduction systems on all four boilers is expected to be in excess of $210,000,000

    1995-01-01

    A discussion of future changes in the electric power utility industry in Canada was presented. The impacts of deregulation were considered, including increased competition, and reduced profits resulting from it. Restructuring measures taken by BC Hydro to prepare for industry changes were described. Competition was not only expected to result from new electric utilities, but also gas utilities that are establishing themselves in the home heating business. Emphasis was placed on making the utilities' priorities, the same as their customers'. Flexibility of rate scheduling and increased dependence on customer-owned generation were needed to remain competitive. Exportation of surplus electricity and development of power utilities in developing nations was considered as a potentially lucrative development strategy. It was suggested that making use of strategic alliances within Canada and worldwide, will help to keep utilities ahead of the competition. A warning was issued to the effect that environmental concerns must always be considered well in advance of regulations since they are continually becoming more stringent. Making common cause with customers, and continuous improvement were considered to be the most important keys to future success for the industry

    Population pressures leading to changes in India, China, and South America during the next twenty-five years and the resulting revolutionary shifts in the world's major economic axes, such as growth in populations, in demand for consumer goods, in production capacities, and in energy demand, will demand greater international cooperation according to a former premier of the province of Quebec. He stressed in particular, the contributions that large electrical utilities can play in this world-wide transformation. He predicted the possibility of privatization and an extended role in international energy activities for Hydro-Quebec as a result of these major demographic and economic changes in Asia and South America, and the consequent decline in the economies of the G7 countries. Major capital investments abroad, and the formation of networks of domestic and foreign partnerships in the developing world were predicted to be the key to the survival and continuing success not only of Hydro-Quebec, but all major utility companies

  15. Electric utility strategies and the emerging industry structure - Part 1

    International Nuclear Information System (INIS)

    Motupalli, S.

    1991-01-01

    The electric utility industry is our most capital intensive industry by far. Over the past few decades, socioeconomic and technological forces have been quietly revolutionizing the way the industry conducts itself. During the 1980s, these changes have been particularly intense, often catching both regulators and regulated ill-prepared to develop effective and profitable strategies to deal with such change. Much has already been written about these changes: independent power producers, competitive procurement of resources, incentive-based regulation, the benefits of affiliated company structures, mergers and consolidation, customer energy conservation, and marketing strategy development are all currently highly popular article and seminar topics. The author's object in this two-part series is to facilitate development of a decision framework to put these various changes in perspective, to help develop effective strategies through better focused and equipped planning methodologies. Gaining an understanding of the role, strengths and weaknesses of the various players in an industry and the structural constraints in which they operate is a necessary precursor to developing effective operating strategies to deal with change or to manipulate industry forces in your favor. Michael Port's popular five forces model provides a convenient way to develop such an understanding. It provides a way to map the industry forces driving profitability, through a review of the strengths, weaknesses and leverage of: current industry players, suppliers to the industry, customers for the industry's product, new entrants into the market, and substitute products providing equal or better value. Part 1 of this series reviews each of these five forces along some key dimensions to determine their direction of change or influence, and whether this change impacts a utility's competitive position favorably or unfavorably

  16. The Municipal Electrical Utilities' role in buying and selling power

    International Nuclear Information System (INIS)

    Crocker, D.I.

    1999-01-01

    Ontario's Municipal Electrical Utilities (MEUs) are the front-line providers of electricity services for most of the consumers in Ontario. MEUs serve 2.8 million customers (about 70 per cent of all power sold in Ontario). The new regulatory regime resulting from Ontario's Energy Competition Act (1998) will significantly impact MEUs. The changes aim to consolidate and rationalize the point of sale provision of power to Ontario customers and increase the efficiency of the sector. The Energy Competition Act (1998) creates a competitive electricity marketplace and provides mechanisms for its operation, but it is the MEUs which will bear the risk of market failures. Some of the changes which will be most important to MEUs are: (1) incorporation, (2) default supplier, and (3) oversight by the OEB. It is the author's view that the move towards open markets in electricity is unlikely to enlarge the decision making power of MEUs. On the contrary, the legislative scheme creates a complex regulatory environment wherein the distribution corporation must strictly comply with the OEB's requirements and public policy concerns in exercising its functions. As the MEUs essentially serve as a buffer in the newly opened retail markets, they must find ways to minimize their risk of market failures or spread the cost so as to remain viable commercial entities. They must also devise new information systems prior to the opening of the new market to deal with customer and default consumer pricing, billing and transfer of customers to and from retailers. Municipal utilities will also have to consider restructuring of their own operations, including determining which businesses should be pursued through competitive affiliates

    Access to electricity is a major issue in West Africa. Governments have a difficult equation to solve. They naturally seek to offer their people a cheap kWh. But they are constrained by a production based largely on oil and therefore highly volatile production costs. How to fix an acceptable tariff, taking into account the investment needs required to expand the network and increase production? This analysis should provide some answers. The study presented in this paper provides a financial analysis of electricity utilities in West Africa. It allows a comparison of performances on a number of key financial ratios related to operations (Earning Before Interest Taxes Debt and Amortization/sales, working capital requirement/sales, days of receivables or payables), investment (net fixed assets/gross fixed assets), bank financing (financial structure, debt/EBITDA, interest expense/EBITDA) and economic and financial returns (Return On Capital Employed, Return On Equity). The conclusion focuses on the growth opportunity that the electricity sector could represent for each country. But this opportunity may only materialize if the EBITDA margins are restored. The available options appear limited and must be assessed taking into account the context of each country: tariff increase, improvement of technical losses or diversification into means of production no longer based primarily on oil or gas. - Highlights: → The study provides a financial analysis of electricity distribution companies in West Africa. → The study highlights generally insufficient EBITDA margins. → The study raises the question of tariffs and contribution to Gross Domestic Product of the electricity sector. → The conclusion focuses on the growth opportunity that the electricity sector could represent for each country.

    Integrated resource planning (IRP) is a process used by many vertically-integrated U.S. electric utilities to determine least-cost/risk supply and demand-side resources that meet government policy objectives and future obligations to customers and, in many cases, shareholders. Forecasts of energy and peak demand are a critical component of the IRP process. There have been few, if any, quantitative studies of IRP long-run (planning horizons of two decades) load forecast performance and its relationship to resource planning and actual procurement decisions. In this paper, we evaluate load forecasting methods, assumptions, and outcomes for 12 Western U.S. utilities by examining and comparing plans filed in the early 2000s against recent plans, up to year 2014. We find a convergence in the methods and data sources used. We also find that forecasts in more recent IRPs generally took account of new information, but that there continued to be a systematic over-estimation of load growth rates during the period studied. We compare planned and procured resource expansion against customer load and year-to-year load growth rates, but do not find a direct relationship. Load sensitivities performed in resource plans do not appear to be related to later procurement strategies even in the presence of large forecast errors. These findings suggest that resource procurement decisions may be driven by other factors than customer load growth. Our results have important implications for the integrated resource planning process, namely that load forecast accuracy may not be as important for resource procurement as is generally believed, that load forecast sensitivities could be used to improve the procurement process, and that management of load uncertainty should be prioritized over more complex forecasting techniques.

  19. Repeated regulatory failures: British electric utilities, 1919--1937

    Science.gov (United States)

    van der Werf, Ysbrand John

    This dissertation uses previously unexamined firm-level data to look at British electric utilities during the 1919--1937 period. The persistent influence of the 1882 and 1888 Electric Lighting Acts had a significant role in perpetuating the inefficient market structure and high costs of the industry. First, I examine factors that influence costs in 1919 and compare the relative cost efficiency of municipally-owned and investor-owned utilities (munis and IOUs). Scale and load factor are found to be more important than ownership in influencing costs, although IOUs enjoy a scale advantage. Given costs, there is no difference in prices between IOUs and munis, and on average prices were 20 percent below monopoly prices. Looking at the 1919--1928 period and examining changes in the industry as measured by the firms' choices in frequency, current, and interconnections with other utilities shows evidence for a great deal of change, which occurred in statistically predictable ways. Utilities are standardizing the type of current produced, and the eventual localized standard frequencies were selected by 1907. There is little in the way of market rivalry between mum's and IOUs but large munis are less likely to build networks and sell in the wholesale market. Finally, I compare the changes that occurred during the 1919--1928 period, under the weak intervention of the Electricity Commissioners, with those of the 1928--1937 period, under the strong intervention of the Central Electricity Board. Without the CEB localized frequency standards would likely have remained in place. The CEB intervened directly in the wholesale market, but contrary to common perceptions, this strong intervention had relatively little impact on trends observed in the industry under the weak intervention of the 1919--1928 period: the CEB reduced prices and costs by no more than about 15 percent and was responsible for at most a quarter of their decline during the 1928--37 period.

  1. Growth strategies of electric utilities in context of deregulation and liberalization of electricity market

    Full Text Available This paper identifies the growth strategies adopted by the electric utilities sector in the context of changes resulting from the deregulation and liberalization of the electricity market. Strategies pursued by the electric utilities sector were rarely the subject of research in the field of strategic management despite the fact that electricity is an indispensable element of everyday life and the economy as a whole. Therefore, a case study of the largest incumbent electric utilities in the Republic of Croatia, Slovenia, Bosnia and Herzegovina, Serbia, Montenegro, and Macedonia has been conducted, and differences in the degree of market liberalization and core features of these companies have been noted. Research findings have shown that the degree of deregulation can affect the growth strategies of electric utilities. In those countries where the degree of deregulation is lower, electric utilities focus on the domestic market. On the other hand, a higher level of deregulation enables electric utilities to achieve their growth through diversification or innovation. Given the fact that the analyzed electric utilities are operating within relatively small economies, they cannot compete with electric utilities in developed countries, and, apart from international electricity trading, are mostly focused on their domestic markets.

    Highlights: • Improving DSM program impacts by targeting high energy users. • DSM energy savings potential hinges on pre-participation performance. • Targeting can benefit different utilities and energy efficiency programs. • Overall performance can be improved by up to 250% via targeting strategies. - Abstract: Electric utilities, government agencies, and private interests in the US have committed and continue to invest substantial resources – including billions of dollars of financial capital – in the pursuit of energy efficiency and conservation through demand-side management (DSM) programs. While most of these programs are deemed to be cost effective, and therefore in the public interest, opportunities exist to improve cost effectiveness by targeting programs to those customers with the greatest potential for energy savings. This article details an analysis of three DSM programs offered by three Florida municipal electric utilities to explore such opportunities. First, we estimate programs’ energy savings impacts; second, we measure and compare energy savings across subgroups of program participants as determined by their pre-intervention energy performance, and third, we explore potential changes in program impacts that might be realized by targeting specific customers for participation in the DSM programs. All three programs resulted in statistically significant average (per-participant) energy savings, yet average savings varied widely, with the customers who performed best (i.e., most efficient) before the intervention saving the least energy and those who performed worst (i.e., least efficient) before the intervention saving the most. Assessment of alternative program participation scenarios with varying levels of customer targeting suggests that program impacts could be increased by as much as 80% for a professional energy audit program, just over 100% for a high-efficiency heat pump upgrade program, and nearly 250% for an attic insulation

    2012-01-01

    The asymmetry of Chinese coal and electricity pricing reforms leads to serious conflict between coal suppliers and electricity utilities. Electricity utilities experience significant losses as a result of conflict: severe coal price fluctuations, and uncertainty in the quantity and quality of coal supplies. This paper explores whether establishing cooperative relationships between coal suppliers and electricity utilities can resolve conflicts. We begin with a discussion of the history of coal and electricity pricing reforms, and then conduct a theoretical analysis of relational contracting to provide a new perspective on the drivers behind the establishment of cooperative relationships between the two parties. Finally, we empirically investigate the role of cooperative relationships and the establishment of mine-mouth power plants on the performance of electricity utilities. The results show that relational contracting between electricity utilities and coal suppliers improves the market performance of electricity utilities; meanwhile, the transportation cost savings derived from mine-mouth power plants are of importance in improving the performance of electricity utilities. - Highlights: ► We discuss the history of coal and electricity pricing reforms. ► The roots of conflicts between electricity and coal firms are presented. ► We conduct a theoretical analysis of relational contracting. ► The role of mine-mouth power plants on the performance of power firms is examined.

    Blair, L.M.

    1988-01-01

    An assessment of the adequacy of the supply of health physicists, nuclear engineers, and other engineers for the nuclear electric utility industry is based on job openings for scientists and engineers in broader nuclear-power-related fields, which include engineering and design, manufacturing, fabrication, supporting services, and government. In assessing the likely adequacy of labor supplies for commercial nuclear power job openings over the next 5 yr, consideration has been given to competing sources of labor demands, including nuclear energy research and development activities, nuclear defense, and the total US economy, and to the likely supply of new graduates. In particular, over the last 3 yr, the number of degrees awarded and enrollments in nuclear engineering programs have declined 12 and 14%, respectively, and in health physics programs, 5 and 14%, respectively. For health physics and nuclear engineers, tight labor market conditions (i.e. labor supplies and demand balanced at relatively high salaries) are expected over the next 5 yr because of declining enrollments and slowly growing employment levels plus job replacement needs. The commercial nuclear power field is expected to face tight labor markets for electrical and materials engineers because of strong competing demands in the economy. Other engineering occupations are likely to have adequate supplies for the nuclear power field but at salaries that continue to be relatively higher than salaries for other professional occupations

    The interest of utilities and governmental agencies in Demand-side management (IDSM) and Integrated Resource Planning (IRP) has increased during recent years also in Finland. From the governmental point of view, the main reason for this has been concern about the environmental effects of electricity supply and consumption. Utilities are mainly interested in cost reductions in electricity supply and distribution caused by DSM. Also improved service to the customer due to DSM has increasing value to utilities. In this project, the main target has been to develop and assess methods for DSM planning from the utility point of view. The final goal is to integrate these methods into the strategic planning of electric utilities

    The impact of regulatory restructuring on demand side management (DSM) was reviewed, drawing on the experiences gained in Norway, England and New Zealand, with a view to determining alternative motivators for energy efficiency in the absence of regulations. The implications of deregulation were examined. It was found that each of the three countries was forced to return to the question of DSM and energy services programs, and the role of utilities. Evidence seemed to indicate that with the removal of the shielding effect of regulation on the utilities generation market, the difference in investment payback between generators and suppliers was likely to approach the levels that exist in other segment of the economy, thus pricing market failure is likely to be removed. However, other market failures may well remain, such as (1) attention to environmental externalities, (2) consumers` inability to influence the efficiency or use of energy consuming equipment, (3) consumers` difficulty in acquiring information on efficiency measures, and in implementing such measures. In view of the Rio de Janeiro obligations policy makers will have to find market mechanisms to remedy these shortcomings. 16 refs.

  13. Estimating potential stranded commitments for U.S. investor-owned electric utilities

    New technologies, low natural gas prices, and federal and state utility regions are restructuring the electricity industry. Yesterday's vertically integrated utility with a retail monopoly franchise may be a very different organization in a few years. Conferences, regulatory-commission hearings, and other industry fora are dominated by debates over the extent and form of utility deintegration, wholesale competition, and retail wheeling. A key obstacle to restructuring the electricity industry is stranded commitments. Past investments, power-purchase contracts, and public-policy-driven programs that made sense in an era of cost-of-service regulation may not be cost-effective in a competitive power market. Regulators, utilities, and other parties face tough decisions concerning the mitigation and allocation of these stranded commitments. The authors developed and applied a simple method to calculate the amount of stranded commitments facing US investor-owned electric utilities. The results obtained with this method depend strongly on a few key assumptions: (1) the fraction of utility sales that is at risk with respect to competition, (2) the market price of electric generation, and (3) the number of years during which the utility would lose money because of differences between its embedded cost of production and the market price

    Demand Side Management (DSM) Programs are becoming important facets in the resource planning activities of many utilities. These programs have made substantial impacts to some utilities during the late 1980's, especially those in the Northeast. They will continue to play major roles in utility activities through the 90's. There are major issues which will be addressed and answered in the 90's in order for DSM to continue to play a role in the 1990's

  15. Computer model for estimating electric utility environmental noise

    Teplitzky, A.M.; Hahn, K.J.

    1991-01-01

    This paper reports on a computer code for estimating environmental noise emissions from the operation and the construction of electric power plants that was developed based on algorithms. The computer code (Model) is used to predict octave band sound power levels for power plant operation and construction activities on the basis of the equipment operating characteristics and calculates off-site sound levels for each noise source and for an entire plant. Estimated noise levels are presented either as A-weighted sound level contours around the power plant or as octave band levels at user defined receptor locations. Calculated sound levels can be compared with user designated noise criteria, and the program can assist the user in analyzing alternative noise control strategies

  16. The effects of Title IV of the Clean Air Act amendments of 1990 on electric utilities: An update

    1997-03-01

    This report presents data and analyses related to Phase I implementation of the Clean Air Act Amendment by electric utilities. It describes the strategies used to comply with the Acid Rain Program in 1995, the effect of compliance on sulfur dioxide emissions levels, the cost of compliance, and the effects of the program on coal supply and demand. The first year of Phase I demonstrated that the market-based sulfur dioxide emissions control system could achieve significant reductions in emissions at lower than expected costs. Some utilities reduced aggregate emissions below legal requirements due to economic incentives; other utilities purchased additional allowances to avoid noncompliance. More than half of the utilities switched to or blended with lower sulfur coal, due to price reductions in the coal market which were partially due to the allowance trading program. 21 figs., 20 tabs.

  17. Investigation into the risk perceptions of investors in the securities of nuclear-dependent electric utilities

    1983-01-01

    Two weeks prior to the Three Mile Island accident, March 15, 1979, the Nuclear Regulatory Commission ordered five operating nuclear plants shut down in order to reexamine safety standards in these plants. Reports in the popular and trade press during this time suggested that these events, particularly the accident at Three Mile Island, caused investors in the securities of electric utilities that had nuclear-generation facilities to revise their risk perceptions. This study was designed to examine the impact of both the Nuclear Regulatory Commission order and the accident at Three Mile Island on investor risk perceptions. Selected categories of electric utilities were chosen to examine any differential risk effects resulting from these events. An asset pricing model devoid of many of the restrictive assumptions of more familiar models was used to model investor behavior. The findings suggest that the events described did cause investors to revise upward their perceptions of systematic risk regarding different categories of electric utilities. More specifically, those electric utilities that were operating nuclear plants in 1979 experienced the largest and most sustained increase in systematic risk. However, electric utilities that in 1979 had no operating nuclear plants, but had planned and committed funds for nuclear plants in the future, also experienced increases in systematic risk

  19. How reliably can climate change and mitigation policy impacts on electric utilities be assessed?

    International Nuclear Information System (INIS)

    1993-01-01

    Numerous mechanisms link climate change and electric utilities. Electricity generation releases radiatively active trace substances (RATS). Significant changes in atmospheric concentration of RATS can lead to a change in regional and global climate regimes. Mitigation action designed to prevent or limit climate change is possible through curbing emissions. Climate change and related mitigation actions impact on electric utilities. Foresight in electric utility planning requires reliable predictions of how the utilities may be affected in the decades ahead. In this paper the impacts of climate change and mitigation policies are noted, and our ability to assess these is reviewed. To this end a suite of models exploring supply and demand questions have been developed. The overall conclusion of the study is that the demand-side uncertainties dominate other unknowns and need to be better characterized and understood. (author)

    The main goal of the paper was to estimate gross domestic product (GDP) based on electricity estimation by artificial neural network (ANN). The electricity utilization was analyzed based on different sources like renewable, coal and nuclear sources. The ANN network was trained with two training algorithms namely extreme learning method and back-propagation algorithm in order to produce the best prediction results of the GDP. According to the results it can be concluded that the ANN model with extreme learning method could produce the acceptable prediction of the GDP based on the electricity utilization.

    In this paper we propose a model to explain the behaviour of the Spanish electrical utility industry during the period 1987-1997, under the then existing regulatory system (Marco Legal Estable). The paper will study the presence of economies of scale, the effect of technological progress and the differences in the efficiency of the different companies within the market. The paper concludes that the Spanish electrical utility industry was not, in fact, characterized by economies of scale during this period, but witnessed a great improvement in efficiency within that period. All the critical market factors remind stable. (author)

    The purpose of this study was to determine whether American psychiatrists believe that DSM-IV is being published too soon after DSM-III-R. The authors conducted a mail survey of the attitudes of practicing psychiatrists (N = 454), residency program directors (N = 128), residents (N = 1,331), and researchers (N = 196) toward the scheduled publication of DSM-IV in the early 1990s. They found that the majority of all four groups believed that DSM-IV is being published prematurely. In contrast to respondents who believed that the timing of DSM-IV is appropriate, those who indicated that it is being published too soon had more recently completed their residency training and also believed that DSM-III-R was published prematurely. There was no association between the psychiatrists' responses and their theoretical orientation, Board certification status, ownership of the DSM manuals, the length of time they had used DSM-III, and the diagnostic manual (DSM-III or DSM-III-R) they were currently using. The belief that DSM-IV is being published too soon could contribute to underuse of DSM-IV by substantial numbers of psychiatrists. Thus, to foster compliance with it, APA must preserve in its efforts to demonstrate that the advantages of publishing it in 1993 outweigh the disadvantages of adopting yet another manual.

  4. The past, present, and future of U.S. utility demand-side management programs

    1996-12-01

    Demand-side management or DSM refers to active efforts by electric and gas utilities to modify customers' energy use patterns. The experience in the US shows that utilities, when provided with appropriate incentives, can provide a powerful stimulus to energy efficiency in the private sector. This paper describes the range and history of DSM programs offered by US electric utilities, with a focus on the political, economic, and regulatory events that have shaped their evolution. It also describes the changes these programs are undergoing as a result of US electricity industry restructuring. DSM programs began modestly in the 1970s in response to growing concerns about dependence on foreign sources of oil and environmental consequences of electricity generation, especially nuclear power. The foundation for the unique US partnership between government and utility interests can be traced first to the private-ownership structure of the vertically integrated electricity industry and second to the monopoly franchise granted by state regulators. Electricity industry restructuring calls into question both of these basic conditions, and thus the future of utility DSM programs for the public interest. Future policies guiding ratepayer-funded energy-efficiency DSM programs will need to pay close attention to the specific market objectives of the programs and to the balance between public and private interests

  6. DIAMOND: A model of incremental decision making for resource acquisition by electric utilities

    Gettings, M.; Hirst, E.; Yourstone, E.

    1991-02-01

    Uncertainty is a major issue facing electric utilities in planning and decision making. Substantial uncertainties exist concerning future load growth; the lifetimes and performances of existing power plants; the construction times, costs, and performances of new resources being brought online; and the regulatory and economic environment in which utilities operate. This report describes a utility planning model that focuses on frequent and incremental decisions. The key features of this model are its explicit treatment of uncertainty, frequent user interaction with the model, and the ability to change prior decisions. The primary strength of this model is its representation of the planning and decision-making environment that utility planners and executives face. Users interact with the model after every year or two of simulation, which provides an opportunity to modify past decisions as well as to make new decisions. For example, construction of a power plant can be started one year, and if circumstances change, the plant can be accelerated, mothballed, canceled, or continued as originally planned. Similarly, the marketing and financial incentives for demand-side management programs can be changed from year to year, reflecting the short lead time and small unit size of these resources. This frequent user interaction with the model, an operational game, should build greater understanding and insights among utility planners about the risks associated with different types of resources. The model is called DIAMOND, Decision Impact Assessment Model. In consists of four submodels: FUTURES, FORECAST, SIMULATION, and DECISION. It runs on any IBM-compatible PC and requires no special software or hardware. 19 refs., 13 figs., 15 tabs.

    In the early 1990s, the United Kingdom (the UK) initiated widespread reforms in the electricity industry through a series of market liberalization policies. Several other countries have subsequently followed the lead and restructured their electricity industry. A major outcome of the deregulation effort is the spate of takeovers, both domestic and global, by electric utility companies. With the entry of new players and increasing competition, the business environment of the electricity industry has changed dramatically. This study analyzes the economic impact of mergers and acquisitions (M&As) in the electric utility industry after deregulation. We have examined acquisitions that took place between 1998 and 2013 in the United States, Canada, the UK, Germany, and France. Although previous studies showed no evidence of a positive effect on acquiring firms through M&As, we find that acquisitions by electric utility companies increased the acquiring firms’ share value and improved their operating performance, primarily through efficiency gains after the deregulation. These results are consistent with the empirical evidence and implications presented by Andrade et al. (2001) that M&A created value for the shareholders of the acquiring and target combined firms. - Highlights: • This study examined mergers and acquisitions (M&A) in electric utility industry. • The sample covered M&A between 1998 and 2013 in North America and Europe. • We found M&A significantly increased acquiring firms’ share value and operating performance. • Deregulation policy realized gains for shareholders without incurring costs for consumers.

    1987-01-01

    Electric utilities and public service commissions have not taken full advantage of the many proven methodologies and techniques available for evaluating complex technological issues. In addition, evaluations performed are deficient in their use of (1) methods for evaluating public attitudes and (2) formal methods of analysis for decision making. These oversight are substantiated through an examination of the literature relevant to electric utility planning. The assessment process known as technology assessment or TA is proposed, and a TA model is developed for route in use in utility planning by electric utilities and state regulatory commissions. Techniques to facilitate public participation and techniques to aid decision making are integral to the proposed model and are described in detail. Criteria are provided for selecting an appropriate technique on a case-by-case basis. The TA model proved to be an effective methodology for evaluating technological issues associated with electric utility planning such as decommissioning nuclear power plants. Through the use of the nominal group technique, the attitudes of a group of residential ratepayers were successfully identified and included in the decision-making process

  16. The case for indexed price caps for U.S. electric utilities

    International Nuclear Information System (INIS)

    Lowry, M.N.

    1991-01-01

    Indexed price caps are a promising alternative to traditional, cost-of-service utility rate regulation. In just a decade, they have sprung from the drawing boards of economists to use by major utilities in a number of industries. Several authors have discussed the merits of indexed price caps for U.S. electric utilities. Despite their efforts, many parties to electric utility policy making are unfamiliar with the subject. This is unsurprising given the policy controversies that already embroil the industry. It is also unfortunate, since indexed price caps may help solve some of the problems that prompt these controversies. Indexed price caps can improve electric utility rate regulation in two ways. Utilities would have strong incentives to improve performance without the micromanagement that increasingly characterizes state-level regulation. Utilities could also be granted more extensive marketing freedoms, since indexes can protect customers from cross-subsidization. Two areas of concern about indexed price cap plans have emerged in recent discussions that the author has held with officials of electric utilities, intervenor groups, and regulatory agencies. Officials are often unclear on plan details, and therefore may not appreciate the degree of flexibility that is possible in plan design. Confusion over the available options in price cap adjustment indexes and the logic behind them is especially widespread. Officials also desire a clearer expression of how indexed price caps can coexist with current regulatory initiatives. This article details the major attributes of index plans, provides a brief history of indexing, discusses index design options in depth, and concludes with a vision of how indexed price caps can be made operational in today's electric utility industry

    Hubbell, Michael

    The purpose of this qualitative study was to determine the skills and knowledge necessary for leaders in the California electric utility industry in 2020. With rapid industry changes, skills to effectively lead and stay competitive are undetermined. Leaders must manage an increasingly hostile social and political environment, incorporate new technology, and deal with an aging workforce and infrastructure. Methodology. This study utilized a qualitative case study design to determine the factors that influence the skills leaders will require in 2020. It incorporated the perspectives of current electric utility leaders while looking with a future lens. Findings. Interviews were conducted with transmission and distribution (T&D) directors at 3 investor-owned public electric utilities headquartered in California. The questions followed an open-ended format to gather responses as perceived by electric utility leaders for each research question category: overall skills, aging workforce, regulation, technology, and leading younger generations. The research resulted in 18 major themes: 5 for overall skills, 3 for aging workforce, 4 for regulation, 3 for technology, and 3 for leading younger generations. Conclusions. The study identified leadership skills including the ability to embrace, leverage, and stay current with technology; understand and provide a clear vision for the future; increase creativity; manage the next set of workers; motivate during a time of great change; prepare for knowledge transfer and change in workforce culture; manage regulatory expectations; expand potential utility opportunities; leverage "big data"; allow worker collaboration; and understand what drives younger generations. Recommendations. California-based electric utility leaders can remain effective by implementing key strategies identified herein. Further research could examine perspectives of additional utility leaders who lead in organizational units outside of T&D, expand the research to

    This study investigates the causality from environmental investment (as a long-term effort) and expenditure (as a short-term effort) to financial performance in the US electric utility industry. The industry is one of the large air polluters in the United States. This empirical study finds that the environmental expenditure under the US Clean Air Act has had a negative impact from 1989 to 2001. The negative impact has become much effective after the implementation of the Title IV Program (1995) of the US Clean Air Act. This study cannot find the influence of environmental investment on financial performance by a statistical test although it indicates a positive impact. In the United States, fossil-fueled power plants such as coal-fired ones still produce a large portion of electricity. The generation structure is inconsistent with the betterment in the US environmental protection and imposes a financial burden to electric utility firms. (author)

  20. Effects of utility demand-side management programs on uncertainty

    International Nuclear Information System (INIS)

    Hirst, E.

    1994-01-01

    Electric utilities face a variety of uncertainties that complicate their long-term resource planning. These uncertainties include future economic and load growths, fuel prices, environmental and economic regulations, performance of existing power plants, cost and availability of purchased power, and the costs and performance of new demand and supply resources. As utilities increasingly turn to demand-side management (DSM) programs to provide resources, it becomes more important to analyze the interactions between these programs and the uncertainties facing utilities. This paper uses a dynamic planning model to quantify the uncertainty effects of supply-only vs DSM + supply resource portfolios. The analysis considers four sets of uncertainties: economic growth, fuel prices, the costs to build new power plants, and the costs to operate DSM programs. The two types of portfolios are tested against these four sets of uncertainties for the period 1990 to 2010. Sensitivity, scenario, and worst-case analysis methods are used. The sensitivity analyses show that the DSM + supply resource portfolio is less sensitive to unanticipated changes in economic growth, fuel prices, and power-plant construction costs than is the supply-only portfolio. The supply-only resource mix is better only with respect to uncertainties about the costs of DSM programs. The base-case analysis shows that including DSM programs in the utility's resource portfolio reduces the net present value of revenue requirements (NPV-RR) by 490 million dollars. The scenario-analysis results show an additional 30 million dollars (6%) in benefits associated with reduction in these uncertainties. In the worst-case analysis, the DSM + supply portfolio again reduces the cost penalty associated with guessing wrong for both cases, when the utility plans for high needs and learns it has low needs and vice versa. 20 refs

  1. Design study of wind turbines, 50 kW to 3000 kW for electric utility applications: Executive summary

    1977-01-01

    Preliminary designs of low power (50 to 500 kW) and high power (500 to 3000 kW) wind generator systems (WGS) for electric utility applications were developed. These designs provide the bases for detail design, fabrication, and experimental demonstration testing of these units at selected utility sites. Several feasible WGS configurations were evaluated, and the concept offering the lowest energy cost potential and minimum technical risk for utility applications was selected. The selected concept was optimized utilizing a parametric computer program prepared for this purpose. The utility requirements evaluation task examined the economic, operational and institutional factors affecting the WGS in a utility environment, and provided additional guidance for the preliminary design effort. Results of the conceptual design task indicated that a rotor operating at constant speed, driving an AC generator through a gear transmission is the most cost effective WGS configuration.

    Two issues pertinent to the DSM-5 proposal for personality pathology, the recovery of DSM-IV personality disorders (PDs) by proposed DSM-5 traits and the validity of the proposed DSM-5 hybrid model which incorporates both personality pathology symptoms and maladaptive traits, were evaluated in a large undergraduate sample (N = 808). Proposed DSM-5 traits as assessed with the Personality Inventory for DSM-5 explained a substantial proportion of variance in DSM-IV PDs as assessed with the Personality Diagnostic Questionnaire-4+, and trait indicators of the six proposed DSM-5 PDs were mostly specific to those disorders with some exceptions. Regression analyses support the DSM-5 hybrid model in that pathological traits and an indicator of general personality pathology severity provided incremental information about PDs. Findings are discussed in the context of broader issues around the proposed DSM-5 model of personality disorders. PMID:22250660

  3. Economic profitability analysis of demand side management program

    This study considers both the internal and external costs of the utility in deriving the avoided capacity cost (ACC) and avoided operating cost (AOC) induced in an electric utility caused by the implementation of a demand side management program (DSM). In calculating the ACC, a multiple objective linear programming model is developed. Meanwhile, the AOC is calculated by considering the differences between the total and specific time period energy consumption ratios before and after the implementation of the DSM program. This study also develops an economic analysis method using Net Present Value and Pay Back Year models to assess the economic profitability of implementing a DSM program from a participant's point of view. The design and construction of a partial load leveling eutectic salt Cooling Energy Storage (CES) air conditioning system in a target office building in Kaohsiung, Taiwan, is discussed in order to simulate the cost benefit of the CES system from the perspective of the utility and from that of the participant. The results confirm the effectiveness of the developed models in simulating the economic benefits of implementing a DSM program from the perspectives of both the utility and the participant

    Performance-Based Ratemaking (PBR) is a form of utility regulation that strengthens the financial incentives to lower rates, lower costs, or improve nonprice performance relative traditional regulation, which the authors call cost-of-service, rate-of-return (COS/ROR) regulation. Although the electric utility industry has considerable experience with incentive mechanisms that target specific areas of performance, implementation of mechanisms that cover a comprehensive set of utility costs or services is relatively rare. In recent years, interest in PBR has increased as a result of growing dissatisfaction with COS/ROR and as a result of economic and technological trends that are leading to more competition in certain segments of the electricity industry. In addition, incentive regulation has been used with some success in other public utility industries, most notably telecommunications in the US and telecommunications, energy, and water in the United Kingdom. In this report, the authors analyze comprehensive PBR mechanisms for electric utilities in four ways: (1) they describe different types of PBR mechanisms, (2) they review a sample of actual PBR plans, (3) they consider the interaction of PBR and utility-funded energy efficiency programs, and (4) they examine how PBR interacts with electric utility resource planning and industry restructuring. The report should be of interest to technical staff of utilities and regulatory commissions that are actively considering or designing PBR mechanisms. 16 figs., 17 tabs.

  7. Economies of scale and vertical integration in the investor-owed electric utility industry

    Thompson, H.G.; Islam, M.; Rose, K.

    1996-01-01

    This report analyzes the nature of costs in a vertically integrated electric utility. Findings provide new insights into the operations of the vertically integrated electric utility and supports earlier research on economics of scale and density; results also provide insights for policy makers dealing with electric industry restructuring issues such as competitive structure and mergers. Overall, results indicate that for most firms in the industry, average costs would not be reduced through expansion of generation, numbers of customers, or the delivery system. Evidently, the combination of benefits from large-scale technologies, managerial experience, coordination, or load diversity have been exhausted by the larger firms in the industry; however many firms would benefit from reducing their generation-to-sales ratio and by increasing sales to their existing customer base. Three cost models were used in the analysis

    Many economists such as Wilson (2002) [Wilson, R., 2002. Architecture of power market, Econometrica, 70, 1299-1340] have considered that there are similarities between electricity and gas services in the US electric utility industry. Hence, they expect a synergy effect between them. However, the two businesses do not have technology similarities at the level that the gas service produces a synergy effect with electricity. To examine whether there is a synergy effect of corporate diversification in the industry, we compare electricity-specialized firms with diversified utility firms in terms of their financial performance and corporate value. The comparison indicates that core business concentration is more effective for electric utility firms than corporate diversification under the current US deregulation policy.

    Brooks, L.D.; D'Souza, R.E.

    1982-01-01

    The impact of the Three Mile Island nuclear-generating-unit failure on the performance of nuclear-dependent electric utilities is examined in this article. A comparative examination of the time series of abnormal returns and risk measures on nuclear-dependent utilities and nondependent utilities prior to the TMI incident, at the time of the incident, and subsequent to it was performed by the authors. The results are consistent with a hypothesis that investors associate a decline in future profitability or increased risk with nuclear-associated utilities. However, the more-objective measures indicate a clear reduction in risk for nuclear-associated utilities since the TMI incident, both in relation to the market as a whole and in relation to electric utilities which are not nuclear-associated. 4 references, 1 figure, 3 tables

    2013-01-01

    After the Fukushima nuclear accident, almost all nuclear power stations continued to stop operation and sharp increase of purchase costs of fossil fuels forced some electric utilities to suffer a deficit. This article presented quantitative analysis of effects of present state on power costs and balance sheets of electric utilities. Levelized costs of electricity increased from 8.6 ¥/kWh (2010) to 11.6 ¥/kWh (2011) and 12.6 ¥/kWh (2012). Total power costs increased from 7.5 Trillion¥(2010) to 9.5 Trillion¥(2011). Due to increase of cost of fossil fuel compensated for nuclear power, electric utilities suffered a net loss of 0.8 Trillion¥ and decreased surplus to 2.5 Trillion¥ in 2011. Net loss of 1.3 Trillion¥ and surplus of 1.2 Trillion¥ was estimated for 2012. This state was beyond the limit of utilities' efforts to reduce costs and uncertain share of power sources became a great risk. Future share of power sources should be judged appropriately from various standpoints (costs, stable supply, energy security and national economic growth) and early public dissemination of new philosophy on share of power sources was highly required.

  12. Environmental assessment for the electric utility system distribution, replacements and upgrades at Lawrence Livermore National Laboratory

    International Nuclear Information System (INIS)

    1992-04-01

    This Environmental Assessment evaluates the environmental effects resulting from the distribution of new electrical service, replacement of inadequate or aging equipment, and upgrade of the existing electrical utility system at Lawrence Livermore National Laboratory. The projects assessed herein do not impact cultural or historic resources, sensitive habitats or wetlands and are not a source of air emissions. The potential environmental effects that do result from the action are fugitive dust and noise from construction and the disposal of potentially contaminated soil removed from certain limited areas of the LLNL site as a result of trenching for underground transmission lines. The actions described in this assessment represent an improved safety and reliability to the existing utility system. Inherent in the increased reliability and upgrades is a net increase in electrical capacity, with future expansion reserve. As with any electrical device, the electrical utility system has associated electric and magnetic fields that present a potential source of personnel exposure. The potential is not increased, however, beyond that which already exists for the present electrical utility system

  13. From franchise to state commission: Regulation of the electric utility industry, 1907 to 1932

    Reutter, Keith Alan

    1997-09-01

    Empirical research into the effects of regulation on industry has been around since the early 1960s. Over the last thirty plus years a number of interesting results have been brought to the fore. For instance, it has been found that regulation of the trucking industry limits entry and increases prices. A similar result has been pointed to in other industries such as commercial airlines and banking. The effect of the state commission form of regulation on the electric utility industry has been less conclusive. State commissions became dominant during the period 1910-1930, replacing local franchising as a method of regulating the electric utility industry. Two competing theories suggest why this transformation took place, the "capture" and "public interest" theories of regulation. The capture theory of regulation suggests that the electric utility industry demanded state regulation as a way to earn above normal profits and reduce competition. The public interest theory suggests the purpose of regulation by state commissions was to benefit the general public by forcing the industry to be competitive. Few studies have tried to determine which theory more aptly describes the actual events that took place. The empirical model developed in Chapter V, is an extension of the current literature. A set of simultaneous equations describing the natural gas and electricity markets is estimated using cross-sectional time-series data from 1907 to 1932. The effect of regulation on the electric utility industry is modeled with a dummy variable taking on a value of one to designate that a state commission had been established. The results suggest the capture theory of regulation best describes the period under study. The empirical estimates indicate that state commissions (1) reduced the rate at which the real price of electricity was falling, (2) had a negative impact on firms entering the industry, (3) had a positive influence on the cost of producing a kwh of electricity, and (4

    Deregulation of the electricity market has changed the business processes of electric utilities profoundly. The paradigm of availability was replaced by economic efficiency. Four requirements are decisive: Implementation of unbundling as required by law - cost reduction to enhance competitive strength - marketing of the utilities' own products - positioning in the new electricity market.

    2001-05-21

    As the electric industry goes through a transformation to a more market-driven model, traditional grounds for utility energy efficiency have come under fire, undermining the existing mechanisms to fund and deliver such services. The challenge, then, is to understand why the electric industry should sustain investments in helping low-income Americans use electricity efficiently, how such investments should be made, and how these policies can become part of the new electric industry structure. This report analyzes the opportunities and barriers to leveraging electric utility energy efficiency assistance to low-income customers during the transition of the electric industry to greater competition.

  20. Regulatory environment and its impact on the market value of investor-owned electric utilities

    Science.gov (United States)

    Vishwanathan, Raman

    While other regulated industries have one by one been exposed to competitive reform, electric power, for over eighty years, has remained a great monopoly. For all those years, the vertically integrated suppliers of electricity in the United States have been assigned exclusive territorial (consumer) franchises and have been closely regulated. This environment is in the process change because the electric power industry is currently undergoing some dramatic adjustments. Since 1992, a number of states have initiated regulatory reform and are moving to allow retail customers to choose their energy supplier. There has also been a considerable federal government role in encouraging competition in the generation and transmission of electricity. The objective of this research is to investigate the reaction of investors to the prevailing regulatory environment in the electric utility industry by analyzing the market-to-book value for investor-owned electric utilities in the United States as a gauge of investor concern or support for change. In this study, the variable of interest is the market valuation of utilities, as it captures investor confidence to changes in the regulatory environment. Initially a classic regression model is analyzed on the full sample (of the 96 investor-owned utilities for the years 1992 through 1996), providing a total number of 480 (96 firms over 5 years) observations. Later fixed- and random-effects models are analyzed for the same full-sample model specified in the previous analysis. Also, the analysis is carried forward to examine the impact of the size of the utility and its degree of reliability on nuclear power generation on market values. In the period of this study, 1992--1996, the financial security markets downgraded utilities that were still operating in a regulated environment or had a substantial percentage of their power generation from nuclear power plants. It was also found that the financial market was sensitive to the size of

    Superconducting Magnetic Energy Storage (SMES) is a promising technology for electric utility load leveling. This paper presents the results of a study to establish the capital cost of SMES as a function of stored energy. Energy-related coil cost and total installed plant cost are given for construction in nominal soil and in competent rock. Economic comparisons are made between SMES and other storage technologies and peaking gas turbines. SMES is projected to be competitive at stored energies as low as 1000 MWh

  2. A Midwest utility's perspective of DSM [demand-side management]: Balancing the needs of customers, shareholders and the environment

    International Nuclear Information System (INIS)

    Collins, G.F.

    1990-01-01

    PSI Energy, a predominately coal-burning Indiana electric utility, is very concerned about the environment and is using demand-side management (DSM) as part of a strategy to balance the sometimes conflicting interests of the environment, the economy, customers and shareholders. Faced with slow growth within its service territory, an abundance of low-cost, high sulfur coal burning baseload capacity, massive future expenditures for acid rain mitigation and a weakened financial state due to a cancelled nuclear project, PSI Energy has taken a novel approach to preserving value for customers, shareholders, the economy and environment. To accomodate Indiana's goal of least cost utility planning, PSI initiated an all-source bidding program in which it solicited bids for peaking capacity or the equivalent. Four parallel but separate solicitations were pursued: combustion turbine manufacturers for PSI owned and operated capacity, other utilities and non-utility generators for purchased power and third parties for demand-side management. PSI's philosophy with respect to bidding can be expressed as: simplicity, flexibility, creativity, partnerships, expeditious and fairness. There is a minimum bid of 5 MW of summer peak demand reduction, and the minimum contract length is 10 years. The entire 550 MW capacity block available to be filled in the program is open to demand-side resources. The ten major evaluation criteria involved in the program are: price, sponsor qualifications, operational impact, marketing plan, technology, financing plan, verification and measurement, form of security, project management plan, and project cost estimates

  3. Consideration of environmental externality costs in electric utility resource selections and regulation

    International Nuclear Information System (INIS)

    Ottinger, R.L.

    1990-01-01

    A surprising number of state electric utility regulatory commissions (half) have started to require consideration of environmental externality costs in utility planning and resource selection. The principal rationale for doing so is that electric utility operations impose very real and large damages to human health and the environment which are not taken into account by traditional utility least cost planning, resource selection procedures, or by government pollution regulation. These failures effectively value the residual environmental costs to society of utility operations at zero. The likely future prospect for more stringent governmental pollution regulation renders imprudent the selection of resources without taking environmental externality costs into consideration. Most regulatory commissions requiring environmental externality consideration have left it to the utilities to compute the societal costs, although a few have either set those costs themselves or used a proxy adder to polluting resource costs (or bonus for non-polluting resources). These commissions have used control or pollution mitigation costs, rather than societal damage costs, in their regulatory computations. This paper recommends that damage costs be used where adequate studies exist to permit quantification, discusses the methodologies for their measurement, and describes the means that have been and might be used for their incorporation

    Electrical utility workers wear thick rubber gloves and often work in the cold. To document the challenge of working in the cold and the effectiveness of different glove/liner combinations in keeping workers' hands warm. Ten experienced male electrical utility employees worked in a controlled temperature walk-in chamber at -20 °C for 45 minutes for each of five glove conditions: standard five-finger rubber gloves with cotton liners and gauntlets, mitten style gloves, a prototype wool liner, and two heating options; glove or torso. Dependent measures were maximum grip force, skin temperatures, finger dexterity and sensitivity to touch, ratings of perceived effort and a rating of thermal sensation. Participants' hand skin temperatures decreased, they perceived their hands to be much colder, their finger sensitivity decreased and their ratings of perceived exertion increased, however their performance did not degrade over the 45 minute trials. The mitten-style gloves showed a smaller drop in skin temperature for the 3rd and 5th digits (pglove conditions. Mitten style gloves kept workers' hands warmer than the standard five finger glove.

    This paper explains effects of market liberalization which will lead to introducing competition in electric power business on demand-side management (DSM), by quoting examples mainly in the United States. The paper also describes the future outlook thereon. The DSM program in the United States has expanded for the period between 1989 through 1994. However, during the last few years, the movements of electric power market liberalization have come to force electric power business entities to change their management strategies and reduction in expense. This situation has resulted in reduction in the DSM budget. Future DSM programs are thought to diversify into the following types: a program such as load management which has effect of reducing expenses and investments in investment time periods of 5 to 10 years, a program effective for users such as high-efficiency motors which have effects of reducing expenses and improving efficiency in investment time periods of 3 to 5 years, a program which will be effective enough if market barriers are removed after the market conversions, but requires subsidies and purchase guarantees, and a social program intended for environmental effects and low-income users. 4 refs., 1 tab.

    In Thailand, electric supply services have all been taken over by the state and operated under state enterprises since 1968. Under a law empowering its monopoly, state utilities accumulated assets and built up their manpower to expand and operate the power system to serve the whole country. During the time of high growth in power demand in early the1990 s, the government initiated a move to privatize state electric utilities, the pace of which was firmed up after 1997, the year of the financial crash. Engagement of independent power producers (IPPs) through the use of long-term power purchase agreements (PPAs) for supply of electric power into the system operated by state electric utilities was also initiated from the mid 1990s. Total capacity of IPPs and Small Power Producers (SPPs) that sell excess power from cogeneration on to the system) rose and by the late 1990s started to create a constraint on system economic dispatch. In 1999 the National Energy Policy Council (NEPC) approved a recommendation of international consultants to transform the electric supply industry into a structure similar to the system in the United Kingdom. The transformation was proposed to precede corporatization and privatization of state electric utilities. The objectives of deregulation were to revoke the monopoly in ESI, to improve transparency in electricity pricing, to reduce debts of state enterprises, and to improve economic efficiency. Industry participants have voiced strong objection to the industry model proposed. With the change of market structure in UK to the New Electricity Trading Arrangement (NETA), the secretariat of NEPC also proposed a new structure similar to NETA. More acceptance from industry participants have been received for the new structure. However, it has been assumed that the proposed structure would bring improvement in system reliability, drawing investment into power generation in a manner that would be efficient.

Total capacity of IPPs and Small Power Producers (SPPs) that sell excess power from cogeneration on to the system, rose and by the late 1990s started to create a constraint on system economic dispatch. In 1999 the National Energy Policy Council (NEPC) approved a recommendation of international consultants to transform the electric supply industry into a structure similar to the system in the United Kingdom. The transformation was proposed to precede corporatization and privatization of state electric utilities. The objectives of deregulation were to revoke the monopoly in ESI, to improve transparency in electricity pricing, to reduce debts of state enterprises, and to improve economic efficiency. Industry participants have voiced strong objection to the industry model proposed. With the change of market structure in UK to the New Electricity Trading Arrangement (NETA), the secretariat of NEPC also proposed a new structure similar to NETA. More acceptance from industry participants have been received for the new structure. However, it has been assumed that the proposed structure would bring improvement in system reliability, drawing investment into power generation in a manner that would be efficient.

    A survey was conducted of Canada's largest distributors of electrical equipment to the utility market. Summaries are presented of the views of the major respondents concerning market trends and future challenges. Distributors have emerged as a supply source to utilities over the past two decades. Before then, electric utilities did virtually all their business directly with the manufacturers and rarely with distributors. One reason for this situation was that direct dealing with manufacturers was perceived by the utilites as providing better access to technical advice. Distributors have grown significantly since then and many have their own expert technical staff and provide full support for their products. Various advantages for utilities in dealing with distributors are noted: ability to supply most needs relatively rapidly from stock, simplification of ordering, improved inventory management, and savings in brokerage and other costs associated with imported equipment

  12. Aiming for market leadership - from electricity utility to pellets manufacturer; Die Marktfuehrerschaft im Visier

    This short article describes the plans of a small Swiss electricity utility to break out of its traditional role in power generation and the distribution of electricity and go into the production of wood pellets. The pellets, which are to be made from waste wood available from a wood processing facility in the utility's own region, are to be produced on a scale which can be described as being quite large for Switzerland. The article discusses this unusual approach for a Swiss power utility, which also operates a wood-fired power station and has diversified into other areas such as electrical house installations and overland power lines. The markets being aimed for are described, including modern low-energy-consumption housing projects.

  13. Nuclear power and the market value of the shares of electric utilities

    Science.gov (United States)

    Lyons, Joseph T.

    The most basic principle of security valuation is that market prices are determined by investors' expectations of the firm's performance in the future. These expectations are generally understood to be related to the risk that investors will bear by holding the firm's equity. There is considerable evidence that financial statements prepared in accordance with accrual-based accounting standards consistent with Generally Accepted Accounting Principles (GAAP) have information content relevant to the establishment of market prices. In 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standard No. 143, "Accounting for Asset Retirement Obligations," changing the accounting standards that must be used to prepare financial statements. This paper investigates the effect that investment in nuclear power has on the market value of electric utilities and the impact on the securities markets of the significant changes in financial statement presentation mandated by this new standard.

    This report describes the financial background of the electric utility industry in VACAR, reports on the present condition of the industry and then assesses the future of this industry. The Virginia-Carolinas subregion (VACAR) of the Southeastern Electric Reliability Council (SERC) was selected for this regional study because of its cooperativeness and its representative mix of powerplants, for example coal, hydro, nuclear, oil. It was found that the supply of future economic electricity is in jeopardy because of the regulatory process, the increasing risk associated with large scale generating stations and the weakening of the nuclear option. A number of options for the future were considered, including deregulation, government ownership and retaining the present system with modifications. The option selected to improve the present condition of the electricity industry was to make the present system work. The present system is sound, and with modifications, problems could be solved within the existing framework. 8 figs., 4 tabs

  15. Implications of the Ontario government's white paper and competition strategies for Ontario's municipal electric utilities

    International Nuclear Information System (INIS)

    Wills, D.L.

    1998-01-01

    The strategies that Municipal Electric Utilities (MEU) should follow to deal with competition were discussed. North Bay Hydro is the 34th largest MEU out of 300 in Ontario but it serves only 23,000 out of 4 million electrical customers in Ontario. Therefore, the main strategy for municipal utilities to ensure their future would be to become part of an alliance and association like the MEA and the SAC - the Strategic Alliance for Competition and Customer Choice. Strong criticism was voiced regarding the contents of the recent Ontario Government White Paper for being vague with regard to electrical distribution and the role of MEUs in Ontario. It was suggested that it is vitally important that MEUs ally themselves with other stakeholders, to resist an Ontario Hydro monopoly, to make sure that prices stay low, to avoid excessive debt and bureaucratic inefficiency, be innovative, and consumer oriented and be prepared to anticipate events and conditions. 3 figs

  19. A Comparative Case Study of Electric Utility Companies’ Use of Energy Democracy in Strategic Communication

    Directory of Open Access Journals (Sweden)

    Meaghan McKasy

    2018-02-01

    Full Text Available A substantial increase in distributed renewable energy resources is changing the face of the energy environment, leading to strategic communication efforts by key stakeholders. The energy democracy movement supports this transformation from fossil fuels to distributed renewable energy and aims for equitable involvement of publics in energy decision making. These tenets challenge utility company earnings as they are directly related to energy sales and infrastructure returns on investment. Proposals by electric utility companies to restructure net-metering policies as a solution to financial issues have been criticized as prohibitive to the success of renewable energy advancement. To address these disagreements, the Edison Electric Institute and a communication firm, Maslansky & Partners, created The Future of Energy: A Working Communication Guide for Discussion. This handbook provides utility companies with strategic communication guidelines to portray themselves as supportive of renewables within a dynamic energy industry. We posit that aspects of the energy democracy movement have been employed by electric utility companies, as shown through the use of the handbook, as a strategy for communicating with customers in discussions around net metering. We examine two case studies in states with recent controversial net-metering policy changes by analyzing utility company websites and press releases for the use of the communication handbook terminology. We found that, in both cases, the suggested language was used to position their companies as pro-renewable energy and their utility-scale projects as more equitable for their customers. In addition, we found differences between each company’s use of key terms from the handbook. We posit that this is due to the temporal context of each net-metering debate at the time of the handbook release. Conclusions and future directions for research in the growing area of energy democracy are discussed.

  20. Potential for increased wind-generated electricity utilization using heat pumps in urban areas

    International Nuclear Information System (INIS)

    Waite, Michael; Modi, Vijay

    2014-01-01

    Highlights: • Large-scale wind power and increased electric heat pumps were evaluated. • A deterministic model of wind power and electricity demand was developed. • Sub-models for space heating and domestic hot water demand were developed. • Increased use of heat pumps can improve the viability of large-scale wind power. • Larger wind power capacity can meet a target utilization rate with more heat pumps. - Abstract: The U.S. has substantial wind power potential, but given wind’s intermittent availability and misalignment with electricity demand profiles, large-scale deployment of wind turbines could result in high electricity costs due to energy storage requirements or low utilization rates. While fuel switching and heat pumps have been proposed as greenhouse gas (GHG) emissions and energy reduction strategies at the building scale, this paper shows that heat pump adoption could have additional system-wide benefits by increasing the utilization of wind-generated electricity. A model was developed to evaluate the effects of coupling large-scale wind power installations in New York State with increased use of electric heat pumps to meet a portion of space heating and domestic hot water (DHW) demands in New York City. The analysis showed significant increases in wind-generated electricity utilization with increased use of heat pumps, allowing for higher installed capacity of wind power. One scenario indicates that 78.5% annual wind-generated electricity utilization can be achieved with 3 GW of installed wind power capacity generated electricity equal to 20% of existing NYC annual electricity demand; if 20% of space heating and DHW demands are provided by heat pumps, the 78.5% utilization rate can be achieved with an increase of total wind power capacity to 5 GW. Therefore, this integrated supply–demand approach could provide additional system-wide emissions reductions

  1. Trends in transmission, distribution, and administration costs for U.S. investor-owned electric utilities

    Fares, Robert L.; King, Carey W.

    2017-01-01

    This paper analyzes the cost of transmission, distribution, and administration for U.S. investor-owned electric utilities. We analyze data reported to the Federal Energy Regulatory Commission (FERC) from 1994 to 2014 using linear regression to understand how the number of customers in a utility's territory, annual peak demand, and annual energy sales affect annual TD&A spending. Then, we use Edison Electric Institute data for 1960 to 1992 to show trends in TD&A spending between 1960 and 2014. We find that the number of customers in a utility's territory is the single best predictor for annual TD&A costs. Between 1994 and 2014, the average cost per customer was $119/Customer-Year for transmission, $291/Customer-Year for distribution, and $333/Customer-Year for utility administration. Total TD&A costs per customer have been approximately $700–$800/Customer-Year since 1960, but the cost per kWh of energy sold was significantly higher in the 1960s because the average customer used less than half as much energy annually versus 2014. Thus, TD&A costs per kWh are likely to increase if kWh energy sales decline in the future unless cost recovery is transitioned to a mechanism not based solely on kWh sales. - Highlights: • U.S. investor-owned electric utility delivery costs from 1960? 2014 are investigated. • Transmission, distribution, and utility administrative costs are analyzed separately. • The number of utility customers is the best predictor for annual delivery costs. • Delivery costs per kWh are likely to increase if kWh sales decrease in the future.

    In 1973, the American Psychiatric Association (APA) removed the diagnosis of "homosexuality" from the second edition of its Diagnostic and Statistical Manual (DSM). This resulted after comparing competing theories, those that pathologized homosexuality and those that viewed it as normal. In an effort to explain how that decision came about, this paper reviews some historical scientific theories and arguments that first led to the placement of homosexuality in DSM-I and DSM-II as well as alternative theories that eventually led to its removal from DSM III and subsequent editions of the manual. The paper concludes with a discussion of the sociocultural aftermath of that 1973 decision.

    Difference similitude matrix (DSM) is effective in reducing information system with its higher reduction rate and higher validity. We use DSM method to analyze the fault data of computer networks and obtain the fault diagnosis rules. Through discretizing the relative value of fault data, we get the information system of the fault data. DSM method reduces the information system and gets the diagnosis rules. The simulation with the actual scenario shows that the fault diagnosis based on DSM can obtain few and effective rules.

    2009-07-01

    Electric utilities are receiving a growing number of requests to attach WiFi equipment to their systems. However, many utilities are not prepared to meet these requests because they have not had enough time to formally review and comment on the particular issues associated with Wi-Fi attachments. Although electric utilities are required to allow the attachments, there is no uniform standard to govern those attachments. This paper discussed the state-of-the-art philosophies and requirements of electric utilities who have allowed WiFi equipment on their systems. The advantages and limitations of each philosophy or practice were also discussed. The requirements for codes and standards in the United States and Canada for high voltage construction were also evaluated.

    Electric utilities today must contain costs at a time when many need to modernize aging systems and all face major changes in technologies, customer preferences and competitive pressures.Most U.S. electric utility facilities are investor-owned, subject to rate and service regulation by state public utility commissions. Regulatory systems under which these utilities operate affect their performance and ability to meet these challenges. In this business environment, multiyear rate plans have some advantages over traditional rate regulation.The report focuses on key design issues and provides case studies of the multiyear rate plan approach, applicable to both vertically integrated and restructured states. Mark Newton Lowry and Matt Makos of Pacific Energy Group Research and Jeff Deason of Berkeley Lab authored the report; Lisa Schwartz, Berkeley Lab, was project manager and technical editor.The report is aimed primarily at state utility regulators and stakeholders in the state regulatory process. The multiyear rate approach also provides ideas on how to streamline oversight of public power utilities and rural electric cooperatives for their governing boards.Two key provisions of multiyear rate plans strengthen cost containment incentives and streamline regulation: 1. Reducing frequency of rate cases, typically to every four or five years 2. Using an attrition relief mechanism to escalate rates or revenue between rate cases to address cost pressures such as inflation and growth in number of customers, independently of the utility’s own cost Better utility performance can be achieved under well-designed multiyear rate plans while achieving lower regulatory costs. Benefits can be shared between utilities and their customers. But plans can be complex and involve significant changes in the regulatory system. Designing plans that stimulate utility performance without undue risk and share benefits fairly can be challenging.This report discusses the rationale for multiyear

    Changes in the DSM-5 eating disorders criteria sought to increase the clarity of the diagnostic categories and to decrease the preponderance of nonspecified eating disorders. The first objective of this study was to analyze how these revisions affect threshold and EDNOS/OSFED eating disorder diagnoses in terms of prevalence, sex ratios, and diagnostic distribution in a student sample. Second, we aimed to compare the impairment levels of participants with a threshold, an EDNOS/OSFED and no diagnosis using both DSM-IV and DSM-5. A sample of 1654 7th and 8th grade students completed self-report questionnaires to determine diagnoses and impairment levels in the context of an eating disorder prevention program in nine German secondary schools. Height and weight were measured. The prevalence of threshold disorders increased from .48% (DSM-IV) to 1.15% (DSM-5). EDNOS disorders increased from 2.90 to 6.23% when using OSFED-categories. A higher proportion of girls was found throughout all the diagnostic categories, and the sex ratios remained stable. The effect sizes of DSM-5 group differences regarding impairment levels were equal to or larger than those of the DSM-IV comparisons, ranging from small to medium. We provide an in-depth overview of changes resulting from the revisions of DSM eating disorder criteria in a German adolescent sample. Despite the overall increase in prevalence estimates, the results suggest that the DSM-5 criteria differentiate participants with threshold disorders and OSFED from those no diagnosis as well as or even more distinctly than the DSM-IV criteria. © 2017 Wiley Periodicals, Inc.

  10. Issues for the electric utilities posed by DT tokamak fusion powerplants

    International Nuclear Information System (INIS)

    Roth, J.R.

    1990-01-01

    The DT tokamak is the mainline approach to magnetic fusion energy in all industrialized countries with a major commitment to fusion research. It achieved this status largely through historical accident and not as the result of considered choice among alternatives. After twenty-five years of intensive tokamak research, it is appropriate to ask whether the path down which the tokamak concept is leading the fusion community is the way to an acceptable powerplant for the electric utilities, or an aberration which should be replaced with an approach more promising in the long term. Issues surrounding the DT tokamak can be grouped in three broad areas: physics; safety/environmental; and engineering/economic. In addition to these problems, detailed engineering design studies of DT tokamak fusion powerplants over a twenty year period have revealed a number of additional problems. Most of thee are related to the presence of tritium and energetic neutron fluxes, which tend to make the cost of electricity of DT tokamaks higher than that of fossil or fission powerplants. These safety and economic issues of the DT tokamak powerplant also appear to be intractable, and have not been made to go away by twenty years of progressively more detailed and extensive engineering design studies

  11. Estimated Value of Service Reliability for Electric Utility Customers in the United States

    Energy Technology Data Exchange (ETDEWEB)

    Sullivan, M.J.; Mercurio, Matthew; Schellenberg, Josh

    2009-06-01

    Information on the value of reliable electricity service can be used to assess the economic efficiency of investments in generation, transmission and distribution systems, to strategically target investments to customer segments that receive the most benefit from system improvements, and to numerically quantify the risk associated with different operating, planning and investment strategies. This paper summarizes research designed to provide estimates of the value of service reliability for electricity customers in the US. These estimates were obtained by analyzing the results from 28 customer value of service reliability studies conducted by 10 major US electric utilities over the 16 year period from 1989 to 2005. Because these studies used nearly identical interruption cost estimation or willingness-to-pay/accept methods it was possible to integrate their results into a single meta-database describing the value of electric service reliability observed in all of them. Once the datasets from the various studies were combined, a two-part regression model was used to estimate customer damage functions that can be generally applied to calculate customer interruption costs per event by season, time of day, day of week, and geographical regions within the US for industrial, commercial, and residential customers. Estimated interruption costs for different types of customers and of different duration are provided. Finally, additional research and development designed to expand the usefulness of this powerful database and analysis are suggested.

  12. Cost functions and the electric utility industry. A contribution to the debate on deregulation

    International Nuclear Information System (INIS)

    Ramos-Real, F.J.

    2005-01-01

    This study analyses the main articles that estimate cost functions in the electricity utility industry with a view to studying of the initial arguments for proposing competition and vertical disintegration. The works reviewed here, in general terms, confirm the initial arguments in favour of the deregulation process, mainly, the exhaustion of scale economies for moderate size firms in generation and the condition of natural monopoly for transmission and distribution. However, the savings obtained from undertaking different activities together should be kept in mind when restructuring the sector. On the other hand, the improvements in productivity deriving from the reforms have not translated into reductions in the price of electricity in many countries. These last two results suggest the need for appropriate market regulation for the deregulation process to translate into an improvement in how the sector works and into benefits for consumers. There is still insufficient empirical literature on these issues due to the fact that the process is still ongoing in many countries and more time will have to transpire before sufficient data is available

  13. Why electric utilities and affiliates are handicapped in a partly regulated and partly competitive environment

    Energy Technology Data Exchange (ETDEWEB)

    St.Marie, S.M.

    1999-11-01

    As the electric utility industry continues to go through the process of restructuring, utilities are finding themselves operating not only as regulated entities but also as firms that compete for customers and sales. Some services, including services associated with distribution, are being unbundled or peeled off from the core of operations and, where possible, are being opened to competition. But these partly regulated and partly competitive areas are treacherous for utilities and their affiliates, who will be handicapped in their competitive efforts and subject to constraints not placed on their competitors. There are good reasons why such difficulties should be expected. And there are guidelines for pricing and competitive positioning that can assist in avoiding the worst problems. The first step is to recognize the archetypes of the regulated electric distribution utility and the competitive firm. In plotting their deregulation strategies, utilities and their affiliates must recognize that they will continue to be disadvantaged by regulators who are more concerned with keeping them in check than freeing them to compete.

  14. Does employee safety influence customer satisfaction? Evidence from the electric utility industry.

    Science.gov (United States)

    Willis, P Geoffrey; Brown, Karen A; Prussia, Gregory E

    2012-12-01

    Research on workplace safety has not examined implications for business performance outcomes such as customer satisfaction. In a U.S. electric utility company, we surveyed 821 employees in 20 work groups, and also had access to archival safety data and the results of a customer satisfaction survey (n=341). In geographically-based work units where there were more employee injuries (based on archival records), customers were less satisfied with the service they received. Safety climate, mediated by safety citizenship behaviors (SCBs), added to the predictive power of the group-level model, but these two constructs exerted their influence independently from actual injuries. In combination, two safety-related predictor paths (injuries and climate/SCB) explained 53% of the variance in customer satisfaction. Results offer preliminary evidence that workplace safety influences customer satisfaction, suggesting that there are likely spillover effects between the safety environment and the service environment. Additional research will be needed to assess the specific mechanisms that convert employee injuries into palpable results for customers. Better safety climate and reductions in employee injuries have the potential to offer payoffs in terms of what customers experience. Copyright © 2012 National Safety Council and Elsevier Ltd.

    International Nuclear Information System (INIS)

    Cox, A.J.

    1999-01-01

    In this article, the author reviews FERC's current procedures for undertaking competitive analysis. The current procedure for evaluating the competitive impact of transactions in the electric utility industry is described in Order 592, in particular Appendix A. These procedures effectively revised criteria that had been laid out in Commonwealth Edison and brought its merger policy in line with the EPAct and the provisions of Order 888. Order 592 was an attempt to provide more certainty and expedition in handling mergers. It established three criteria that had to be satisfied for a merger to be approved: Post-merger market power must be within acceptable thresholds or be satisfactorily mitigated, acceptable customer protections must be in place (to ensure that rates will not go up as a result of increased costs) and any adverse effect on regulation must be addressed. FERC states that its Order 592 Merger Policy Statement is based upon the Horizontal Merger Guidelines issued jointly by the Federal Trade Commission and the Antitrust Division Department of Justice (FTC/DOJ Merger Guidelines). While it borrows much of the language and basic concepts of the Merger Guidelines, FERC's procedures have been criticized as not following the methodology closely enough, leaving open the possibility of mistakes in market definition

    1998-07-27

    In the liberalised electric power market, satisfying customers is a very important objective of utilities, as customers are free to enter into supply contracts with competitors in the market. Satisfaction of customers enhances customer loyalty, as many electric utilities know by now, but only few utilities have a clear picture of the level of satisfaction of their customers, and of their standing in their customers` opinion in comparison with other marketers. The article explains approaches and methods for a systematic and well-founded survey of customers and assessment of customer satisfaction. (orig./CB) [Deutsch] In einem liberalisierten Elektrizitaetsmarkt kommt der Kundenzufriedenheit eine zentrale Bedeutung zu. Diese ist massgebend dafuer, ob ein Kunde zu einem anderen Anbieter wechselt oder nicht. Hohe Kundenzufriedenheit bedeutet hohe Kundenbindung.

Wie dargestellt wird, laesst sich ein solches Bild nur ueber eine systematische und fundierte Messung der Kundenzufriedenheit gewinnen. (orig./RHM)

    In order to bring an electric utility component into the study of hot dry rock geothermal energy called for in the Energy Policy Act of 1992 (EPAct), EPRI organized a one-day conference in Philadelphia on January 14,1993. The conference was planned as the first day of a two-day sequence, by coordinating with the U.S. Geological Survey (USGS) and the U.S. Department of Energy (DOE). These two federal agencies were charged under EPAct with the development of a report on the potential for hot dry rock geothermal energy production in the US, especially the eastern US. The USGS was given lead responsibility for a report to be done in association with DOE. The EPRI conference emphasized first the status of technology development and testing in the U.S. and abroad, i.e., in western Europe, Russia and Japan. The conference went on to address the extent of knowledge regarding the resource base in the US, especially in the eastern half of the country, and then to address some practical business aspects of organizing projects or industries that could bring these resources into use, either for thermal applications or for electric power generation.

  19. Measuring corporate social responsibility using composite indices: Mission impossible? The case of the electricity utility industry

    Full Text Available Corporate social responsibility is a multidimensional concept that is often measured using diverse indicators. Composite indices can aggregate these single indicators into one measurement. This article aims to identify the key challenges in constructing a composite index for measuring corporate social responsibility. The process is illustrated by the construction of a composite index for measuring social outcomes in the electricity utility industry. The sample consisted of seventy-four companies from twenty-three different countries, and one special administrative region operating in the industry in 2011. The findings show that (1 the unavailability of information about corporate social responsibility, (2 the particular characteristics of this information and (3 the weighting of indicators are the main obstacles when constructing the composite index. We highlight than an effective composite index should has a clear objective, a solid theoretical background and a robust structure. In a practical sense, it should be reconsidered how researchers use composite indexes to measure corporate social responsibility, as more transparency and stringency is needed when constructing these tools.

    This study describes the occurrence of work-related injuries from thermal-, electrical- and chemical-burns among electric utility workers. We describe injury trends by occupation, body part injured, age, sex, and circumstances surrounding the injury. This analysis includes all thermal, electric, and chemical injuries included in the Electric Power Research Institute (EPRI) Occupational Health and Safety Database (OHSD). There were a total of 872 thermal burn and electric shock injuries representing 3.7% of all injuries, but accounting for nearly 13% of all medical claim costs, second only to the medical costs associated with sprain- and strain-related injuries (38% of all injuries). The majority of burns involved less than 1 day off of work. The head, hands, and other upper extremities were the body parts most frequently injured by burns or electric shocks. For this industry, electric-related burns accounted for the largest percentage of burn injuries, 399 injuries (45.8%), followed by thermal/heat burns, 345 injuries (39.6%), and chemical burns, 51 injuries (5.8%). These injuries also represented a disproportionate number of fatalities; of the 24 deaths recorded in the database, contact with electric current or with temperature extremes was the source of seven of the fatalities. High-risk occupations included welders, line workers, electricians, meter readers, mechanics, maintenance workers, and plant and equipment operators.

    Many regulators, utilities, customer groups, and other stakeholders are reevaluating existing regulatory models and the roles and financial implications for electric utilities in the context of today’s environment of increasing distributed energy resource (DER) penetrations, forecasts of significant T&D investment, and relatively flat or negative utility sales growth. When this is coupled with predictions about fewer grid-connected customers (i.e., customer defection), there is growing concern about the potential for serious negative impacts on the regulated utility business model. Among states engaged in these issues, the range of topics under consideration is broad. Most of these states are considering whether approaches that have been applied historically to mitigate the impacts of previous “disruptions” to the regulated utility business model (e.g., energy efficiency) as well as to align utility financial interests with increased adoption of such “disruptive technologies” (e.g., shareholder incentive mechanisms, lost revenue mechanisms) are appropriate and effective in the present context. A handful of states are presently considering more fundamental changes to regulatory models and the role of regulated utilities in the ownership, management, and operation of electric delivery systems (e.g., New York “Reforming the Energy Vision” proceeding).

  2. Financial impacts of nonutility power purchases on investor-owned electric utilities

    1994-06-01

    To assist in its these responsibilities in the area of electric power, EIA has prepared this report, Financial Impacts of Nonutility Power Purchases on Investor-Owned Electric Utilities. The primary purpose of this report is to provide an overview of the issues surrounding the financial impacts of nonutility generation contracts (since the passage of the Public Utility Regulatory Policies Act of 1978) on investor-owned utilities. The existing concern in this area is manifest in the provisions of Section 712 of the Energy Policy Act of 1992, which required State regulatory commissions to evaluate various aspects of long-term power purchase contracts, including their impact on investor-owned utilities` cost of capital and rates charged to customers. The EIA does not take positions on policy questions. The EIA`s responsibility is to provide timely, high quality information and to perform objective, credible analyses in support of the deliberations by both public and private decision-makers. Accordingly, this report does not purport to represent the policy positions of the US Department of Energy or the Administration.

    In this article, the author reviews FERC's current procedures for undertaking competitive analysis. The current procedure for evaluating the competitive impact of transactions in the electric utility industry is described in Order 592, in particular Appendix A. These procedures effectively revised criteria that had been laid out in Commonwealth Edison and brought its merger policy in line with the EPAct and the provisions of Order 888. Order 592 was an attempt to provide more certainty and expedition in handling mergers. It established three criteria that had to be satisfied for a merger to be approved: Post-merger market power must be within acceptable thresholds or be satisfactorily mitigated, acceptable customer protections must be in place (to ensure that rates will not go up as a result of increased costs) and any adverse effect on regulation must be addressed. FERC states that its Order 592 Merger Policy Statement is based upon the Horizontal Merger Guidelines issued jointly by the Federal Trade Commission and the Antitrust Division Department of Justice (FTC/DOJ Merger Guidelines). While it borrows much of the language and basic concepts of the Merger Guidelines, FERC's procedures have been criticized as not following the methodology closely enough, leaving open the possibility of mistakes in market definition.

  5. The Effects of Rising Interest Rates on Electric Utility Stock Prices: Regulatory Considerations and Approaches

    This technical brief identifies conditions under which utility regulators should consider implementing policy approaches that seek to mitigate negative outcomes due to an increase in interest rates. Interest rates are a key factor in determining a utility’s cost of equity and investors find value when returns exceed the cost of equity. Through historical observations of periods of rising and falling interest rates and application of a pro forma financial tool, we identify the key drivers of utility stock valuations and estimate the degree to which those valuations might be affected by increasing interest rates.3 We also analyze the efficacy of responses by utility regulators to mitigate potential negative financial impacts. We find that regulators have several possible approaches to mitigate a decline in value in an environment of increasing interest rates, though regulators must weigh the tradeoffs of improving investor value with potential increases in customer costs. Furthermore, the range of approaches reflects today’s many different electric utility regulatory models and regulatory responses to a decline in investor value will fit within state-specific models.

  6. Relative Pricing of Publicly Traded U.S. Electric Utility Companies

    Science.gov (United States)

    Jewczyn, Nicholas Stephen

    In the financial turmoil of 2008, U.S. firms reported debt-ratios that differed from the debt-ratios calculated from balance sheets. The problem is that investors bought common stock expecting initial investment return and lost money when companies delisted. The purpose of this quantitative study was to determine sample securities pricing with the application of synthetic assets and debt accrued. Addressed in the research questions was whether those securities were (a) underpriced compared with return-on-assets (ROA), (b) overpriced compared with ROA, (c) a debt-ratio higher than 60% and also overpriced, (d) underpriced with a synthetic asset added, or (e) related by relative pricing to variant pricing and market capitalization. The study's base theory was Pan's efficient market hypothesis (EMH) of security price prediction of market prices versus model prices. The data from the financial statements of 16 publicly traded U.S. electric utility companies were analyzed via correlations and multiple regression analyses to determine securities pricing and suitability. The findings from the analyses of the sample's variables of market price, book value, market-to-book, and study constructed variables from those variable data were statistically significant. The alternate hypotheses were accepted for all 5 research questions since the analytical operationalization of the hypothetical constructs led to significant relationships. Results suggest that the use of more pricing determinants in securities evaluation may lead to investors losing less money and earning the expected returns for a more efficient capital market, leading to a stronger economy and macroeconomic stability.

  7. Organizational change, restructuring and downsizing: The experience of employees in the electric utility industry

    Korns, Michael T.

    This research examines the experience of employees working in the electric utility industry during a time when it was undergoing significant transformation. It was undertaken to examine this phenomenon in the context of how the history and nature of the industry's environment, and specifically regulatory effect of regulation, led to an organizational form characterized by stability, structure and inertial resistance to change. A case study approach was used to examine the effect of deregulation on an organization in the industry, and specifically how their actions impacted employees working there. A phenomenological approach was used to explore employee perceptions of the organizational culture and employment relationship there both prior to and after implementation of a reorganization and downsizing that resulted in the first significant employee layoffs in the history of the organization. Data gathering consisted of conducting semi-structured interviews with current and former employees of the company who experienced the phenomena. Analysis of the data show that employees in this organization perceived an unusually strong psychological contract for stable employment and the expectation that it would continue, despite the prevalence of corporate downsizing and restructuring at the time. This psychological contract and the importance of career employment was found to be particularly significant for women who were hired during a period of time when gender and pregnancy discrimination was prevalent. Findings demonstrate that, given the historical stability and strong inertial resistance in the organization, company leadership did not effectively communicate the need, or prepare employees sufficiently for the significance of the changes or the effect they had on the organization. Findings also revealed that employees perceived the methods used to select individuals for layoff and exit from the company violated principles of organizational justice for distributional

    The article explains to what extent suitable measures can be realized and supported in a municipality with municipal energy concepts or even climate protection concepts. The target is to attain with limited financial means the most favourable economic and ecological effects in the municipality or in the region. Many electric utilities have in the last years forced the realization of energy conservation measures and have become energy service companies. With their expert knowledge they are ideal partners for politics, public adminstration and citizens. They have the best qualificatons for the development and realization of municipal concepts. In many cases it shows that with detailed studies the target can be quicker and more effectively attained as with extensive, time-consuming and expensive studies which are not particularly realization-oriented. The report is to give examples which might be helpful for the development of a concept.

  9. The regulatory treatment of adverse outcomes: Empirical evidence from the electric utility industry

    International Nuclear Information System (INIS)

    Ryan, N.E.

    1991-01-01

    This dissertation consists of two essays, both of them empirical studies using data from the US electric utility industry. Part I focuses on utilities' investment behavior, while Part II examines regulatory policy toward the industry. The first paper presents an analysis of utilities' decisions about whether to continue or cancel nuclear construction projects. During the seventies and eighties, changes in economic conditions and regulatory policy radically altered the costs and benefits of nuclear power. This study seeks to determine whether regulators pursued policies which induced utilities to employ socially efficient criteria in re-evaluating ongoing projects. The analysis also yields insights into regulators' distributional goals. Results based on data for 1978-84 are consistent with the capture theory hypothesis, which holds that regulators weigh industry interests more heavily than consumer interests. A test for structural change provides no support for the contention that the relative importance of consumer interests increased over this period. These empirical findings are inconsistent with a standard (and essential) assumption of theoretical principal-agent models of rate-of-return regulation, that regulators value consumers' payoffs more than utility profits. The second paper examines regulatory policy toward generating facilities that entered commercial service during the years 1983-88. In a significant departure from past practice, state public utility commissions often denied utilities full recovery of their investments in new plants. Although such ex post disallowances have an important efficiency rationale, they also provide a means for opportunistic regulators to effect transfers between utilities' ratepayers and shareholders. A probit model was used to assess the impact on the probability of a disallowance of firm and project characteristics as well as attributes of a state's political and institutional environment

    Integrated resource planning (IRP) is an important regulatory process used in many U.S. states to formulate and evaluate least-cost and risk-assessed portfolios to meet future load requirements for electric utilities. In principle, effective implementation of IRP seeks to assure regulators and the public that utility investment decisions, given uncertainty, are as cost-effective as possible. However, to date, there is no empirical assessment on the effectiveness of IRP implementation. In this analysis, we compare planning, procurement processes and actual decisions for a sample of twelve load serving entities (LSEs) across the Western U. S. from 2003-2014. The 2008/2009 recession provides a unique “stress test” to the planning process and offers an excellent opportunity to trace how procurement decisions responded to this largely unforeseen event. In aggregate, there is a general alignment between planned and procured supply-side capacity. However, there are significant differences in the choice of supply-side resources and type of ownership for individual LSEs. We develop case studies for three LSEs and find that subsequent plans differ significantly due to changes in the planning environment and that procurement decisions in some cases are impacted by factors that are not accounted for in the planning process. Our results reveal that a limited amount of information produced during the long-term planning process (e.g., forecasts, methods, and least cost/risk portfolios) are ultimately used during the procurement process, and that the latter process relies extensively on the most recent information available for decision making. These findings suggest that states' IRP rules and regulations mandating long-term planning horizons with the same analytical complexity throughout the planning period may not create useful information for the procurement process. The social value of a long-term planning process that departs from procurement and the balance between

    1993-01-01

    One of the most popular demand-side management (DSM) programs currently being sponsored by electric utilities is the removal of old fluorescent light ballasts and replacing them with more efficient models. This type of program, however, can produce a substantial waste stream of the old ballasts, many of which contain Polychlorinated Biphenyl(s) (PCBs), a regulated hazardous substance. The proper disposal of spent light ballasts should be an integral component of DSM programs. This paper will discuss the experience that New England Electric System (NEES) 1 has had with disposing of spent light ballasts resulting from the implementation of our Small Commercial ampersand Industrial Program (a direct install lighting program which provides for the installation of energy efficient lighting measures which include fluorescent fixtures, ballasts and lamps, specular reflectors, compact fluorescent systems, high intensity discharge fixtures, and occupancy sensors. This innovative program is one of the largest in the country and has achieved over 6,000 installations). In this paper, we will review why PCBs are classified as hazardous substances and what effect State and Federal regulations have on the transportation and disposal of ballasts that contain PCBs. Second, we will explain our ballast disposal process which includes collecting, processing, storing, shipping and ultimate disposal. Third, we will discuss our experiences with two different methods of disposal - incineration and recycling. And last we will report on program results

    The Childhood Autism Rating Scale, Second Edition (CARS2; 2010) includes two rating scales; the CARS2-Standard Version (CARS2-ST) and the newly developed CARS2-High Functioning Version (CARS2-HF). To assess the diagnostic agreement between the CARS2 and DSM-IV-TR versus DSM-5 criteria for Autism Spectrum Disorder (ASD), clinicians at community based centers of the University of North Carolina TEACCH Autism Program rated participants seen for a diagnostic evaluation on symptoms of autism using both the DSM-IV-TR and DSM-5 criteria and either the CARS2-HF or the CARS2-ST. Findings suggest that overall, the diagnostic agreement of the CARS2 remains high across DSM-IV and DSM-5 criteria for autism.

    Full Text Available In 1973, the American Psychiatric Association (APA removed the diagnosis of “homosexuality” from the second edition of its Diagnostic and Statistical Manual (DSM. This resulted after comparing competing theories, those that pathologized homosexuality and those that viewed it as normal. In an effort to explain how that decision came about, this paper reviews some historical scientific theories and arguments that first led to the placement of homosexuality in DSM-I and DSM-II as well as alternative theories that eventually led to its removal from DSM III and subsequent editions of the manual. The paper concludes with a discussion of the sociocultural aftermath of that 1973 decision.

    This report reviews recent DSM shareholder incentive designs and performance at 10 US utilities identifies opportunities for regulators to improve the design of DSM shareholder incentive mechanisms to increase the procurement of cost-effective DSM resources. We develop six recommendations: (1) apply shared-savings incentives to DSM resource programs; (2) use markup incentives for individual programs only when net benefits are difficult to measure, but are known to be positive; (3) set expected incentive payments based on covering a utility's open-quotes hidden costs,close quotes which include some transitional management and risk-adjusted opportunity costs; (4) use higher marginal incentives rates than are currently found in practice, but limit total incentive payments by adding a fixed charge; (5) mitigate risks to regulators and utilities by lowering marginal incentive rates at high and low performance levels; and (6) use an aggregate incentive mechanism for all DSM resource programs, with limited exceptions (e.g., information programs where markups are more appropriate)

  19. A methodology to identify stranded generation facilities and estimate stranded costs for Louisiana's electric utility industry

    Cope, Robert Frank, III

    1998-12-01

    The electric utility industry in the United States is currently experiencing a new and different type of growing pain. It is the pain of having to restructure itself into a competitive business. Many industry experts are trying to explain how the nation as a whole, as well as individual states, will implement restructuring and handle its numerous "transition problems." One significant transition problem for federal and state regulators rests with determining a utility's stranded costs. Stranded generation facilities are assets which would be uneconomic in a competitive environment or costs for assets whose regulated book value is greater than market value. At issue is the methodology which will be used to estimate stranded costs. The two primary methods are known as "Top-Down" and "Bottom-Up." The "Top-Down" approach simply determines the present value of the losses in revenue as the market price for electricity changes over a period of time into the future. The problem with this approach is that it does not take into account technical issues associated with the generation and wheeling of electricity. The "Bottom-Up" approach computes the present value of specific strandable generation facilities and compares the resulting valuations with their historical costs. It is regarded as a detailed and difficult, but more precise, approach to identifying stranded assets and their associated costs. This dissertation develops a "Bottom-Up" quantitative, optimization-based approach to electric power wheeling within the state of Louisiana. It optimally evaluates all production capabilities and coordinates the movement of bulk power through transmission interconnections of competing companies in and around the state. Sensitivity analysis to this approach is performed by varying seasonal consumer demand, electric power imports, and transmission inter-connection cost parameters. Generation facility economic dispatch and transmission interconnection bulk power transfers, specific

    Before May 17, 2005, Korea's nuclear power plant (hereinafter referred to as 'NNP') regulation system was two-pronged. Every NPP system consists of primary or secondary system, and each type was respectively regulated by the Atomic Energy Act(hereinafter referred to as 'AEA') and the Electric Utility Act(hereinafter referred to as 'EUA'). This unusual regulatory regime gave rise to a number of problems with respect to operation and safety. For this reason, the Enforcement Regulation of AEA and applicable Notice were revised on May 17, 2005 to the effect that all regulation on NPPs subject to EUA was brought under the purview of AEA, except regulation on business license for nuclear power generation under Article 7 of EUA and approval of plan of works for setting up electric installations (hereinafter referred to as 'construction plan') (including approval of any changes; the same shall apply hereinafter) under Article 61 thereof. From the point of view of the Ministry of Science and Technology, the regulation of NPPs by a single law has enhanced their safety. However, the Ministry of Commerce, Industry and Energy retains regulatory authority regarding NPPs. It reviews and approves construction plans for secondary system pursuant to Article 61 of EUA and Article 28 of the Enforcement Regulation thereof. This situation arose because Article 28 of the Enforcement Regulation of EUA continues to provide for matters related with nuclear power. Therefore, continued control of NPPs under EUA ignores the relationship and respective nature of AEA and EUA. There is also possibility of violation of a superseding law. Even if said provision is not in violation of a superseding law, Article 28 of the Enforcement Regulation of EUA poses the possibility of overlapping regulation, which may violate the principle of prohibiting excessive regulation, one of the principles of the Korean Constitution. Assessment of the dual regulatory system for review of secondary system requires (i

  1. Affairs of power: Restructuring California's electric utility industry, 1968-1998

    Science.gov (United States)

    Myers, William Allan

    This dissertation studies the process of change in the political economy of electric utilities. Following two decades of continual growth during the nation's post-World War Two economic and population boom, the electric power industry confronted increasing challenges to its traditional operating practices and cultural values, nowhere with greater intensity than in California. Pressure for change came from outside forces who opposed utilities' business practices, assailed their traditional vertically-integrated structure, questioned the political assumptions that sustained their monopoly status, and ultimately wrested away access to the once tightly controlled technology of electric generation and transmission. Because managers of both investor-owned and publicly-owned utilities continued to rely upon long-standing economic and technical assumptions derived from deeply held cultural values sustained by decades of business success, they were rendered unable to comprehend and unwilling to accommodate change. Persistent mistrust between the publicly-owned and privately-owned sectors further weakened the industry's ability to work cooperatively in the face of crucial challenges. Thus encumbered by endemic structural jealousy, technological path dependency, and organizational stasis, the industry did not respond with sufficient innovation to new social values and altering economic conditions, ultimately resulting in the discarding of the old political economy of regulated monopolism. Five precepts of economic history are identified as crucial elements of the process of change. First, the tension between protection and entry, and the related issue of access to technology, contributes to creation and modification of the political economy in which economic institutions function. Second, submission to governmental regulatory powers allows certain industries to control entry, restrict access, and protect themselves from the dynamics of competitive change. Third, an

DSM architecture greatly simplifies the development of parallel programs having good performance on a few processors. However, to achieve a good program scalability on DSM computers requires that the user understand data flow in the application and use various techniques to avoid data traffic congestions. In this paper we discuss a number of such techniques, including data blocking, data placement, data transposition and page size control and evaluate their efficiency on the NAS (NASA Advanced Supercomputing) Parallel Benchmarks. We also present a tool which automates the detection of constructs causing data congestions in Fortran array oriented codes and advises the user on code transformations for improving data traffic in the application.

    A key utility regulatory reform undertaken since 1989 allows utilities to recover the lost revenue incurred through successful operation of demand-side management (DSM) programs. Net lost revenue adjustment (NLRA) mechanisms are states preferred approach to lost revenue recovery from DSM programs. This paper examines the experiences states and utilities are having with the NLRA approach. The paper has three objectives: (1) determine whether NLRA is a feasible and effective approach to the lost-revenue disincentive for utility DSM programs, (2) identify the conditions linked to effective implementation of NLRA mechanisms and assess whether NLRA has changed utility investment behavior, and (3) suggest improvements to NLRA mechanisms. Contrary to the concerns raised by some industry analysts, our results indicate NLRA is a feasible approach. Seven of the ten states we studied report no substantial problems with their approach. We observe several conditions linked to effective NLRA implementation. Observed changes in utility investment behavior occur after implementation of DSM rate reforms, which include deployment of NLRA mechanisms. Utilities in states with lost revenue recovery invest more than twice as much in DSM as do utilities in other states.

    There are 6 natural gas distribution companies in Canada with formal, ratepayer-funded demand side management (DSM) programs. However, the general characteristics and regulatory environment of these companies varies greatly. With the exception of Enbridge Gas and Union Gas, each company is located in a different province, which means that companies face different energy regulations and energy efficiency policies. An introduction to DSM and its regulation in Canada was presented, as well as an overview of common models in Canada, and the general considerations involved in designing a regulatory framework were discussed. Regulatory design options for natural gas demand-side management regulatory frameworks were evaluated. The major factors that influence the frameworks were analyzed, and the characteristics of a successful DSM program were outlined. The research methodology for this paper consisted of telephone interviews with policy-makers, regulators, non-governmental organizations and regulatory affairs personnel from local distribution companies. Results indicated the importance of a clear policy framework that provides direction for DSM designers. The common elements for a successful regulatory framework were considered to be a systems approach to the definition of DSM; clear regulatory rules; a long-term predictable source and level of DSM funding that reflected the maturity of the DSM market; an alignment of government energy policies and DSM regulatory frameworks; and recognition and capturing of the broad range of DSM benefits

    1998-07-01

    With the support of the Inter-American Development Bank, the Global Environment Facility of the World Bank, and the Rockefeller Foundation, the national electric utility in Jamaica (Jamaica Public Service Company) has begun an assessment of the technical, economic, and financial opportunities for achieving demand-side management (DSM) energy savings in the air conditioning and refrigeration end uses. The feasibility and cost effectiveness of specific measures is being assessed for both the residential and commercials segments. While structures as a traditional load-research-based market assessment, the project uses ethnographic data collection and analysis techniques and involves collaboration with local contractors. The skills of local experts are being taped to identify and interview the key market players, and to develop an understanding of the barriers to and opportunities for energy efficiency present in the evolving equipment markets. The paper outlines methods and presents preliminary case study results for the air conditioning market. The authors identify major groups of market players and dominant types of equipment, and provide an overview of market dynamics. The volume of sales passing through both formal and informal distribution channels is estimated and market barriers are identified. Based on the findings of the study, recommendations will be made for future program and policy initiatives designed to mitigate selected barriers in each of the supply chains.

  7. Methodology and results of the impacts of modeling electric utilities: a comparative evaluation of MEMM and REM

    International Nuclear Information System (INIS)

    1981-09-01

    This study compares two models of the US electric utility industry including the EIA's electric utility submodel in the Midterm Energy Market Model (MEMM), and the Baughman-Joskow Regionalized Electricity Model (REM). The method of comparison emphasizes reconciliation of differences in data common to both models, and the performance of simulation experiments to evaluate the empirical significance of certain structural differences in the models. The major research goal was to contrast and compare the effects of alternative modeling structures and data assumptions on model results; and, particularly to considered each model's approach to the impacts of generation technology and fuel use choices on electric utilities. The methodology used was to run the REM model first without and, then, with a representation of the Power Plant and Industrial Fuel Act of 1978, assuming medium supply and demand curves and varying fuel prices. The models and data structures of the two models are described. The original 1978 data used in MEMM and REM are analyzed and compared. The computations and effects of different assumptions on fuel use decisions are discussed. The adjusted REM data required for the experiments are presented. Simulation results of the two models are compared. These results represent projections for 1985, 1990, and 1995 of: US power generation by plant type; amounts of each type of fuel used for power generation; average electricity prices; and the effects of additional or fewer nuclear and coal-fired plants. A significant result is that the REM model exhibits about 7 times as much gas and oil consumption in 1995 as the MEMM model. Continuing simulation experiments on MEMM are recommended to determine whether the input data to MEMM are reasonable and properly adjusted

    In spring 2013 the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) edited by the American Psychiatric Association was published. The DSM-5 has also brought some important changes regarding bipolar disorders. The goal of this manuscript is to review the novelties in DSM-5 and to evaluate the implications of these changes. The diagnostic criteria as well as the additional remarks provided in the running text of DSM-5 were carefully appraised. For the first time diagnostic criteria are provided for disorders which up to now have been considered as subthreshold bipolar disorders. Furthermore, mixed episodes were eliminated and instead a mixed specifier was introduced. An increase in goal-directed activity/energy is now one of the obligatory symptoms for a (hypo)manic episode. Diagnostic guidance is provided as to when a (hypo)manic episode that has developed during treatment with an antidepressant has to be judged to be causally related to antidepressants and when this episode has only occurred coincidentally with antidepressant use. While some of the novelties are clearly useful, e.g. addition of increased goal-directed activity/energy as obligatory symptom for (hypo)manic episodes, this remains to be demonstrated for others, such as the definition of various subthreshold bipolar disorders.

    1998-01-01

    In this paper, we analyze past and current cost structure of commercial nuclear power plants in Japan based on annual corporate financial statements published by the Japanese electric utility companies, instead of employing the conventional methodology of evaluating the generation cost for a newly constructed model plant. The result of our study on existing commercial nuclear plants reveals the increasing significance of O and M and fuel cycle costs in total generation cost. Thus, it is suggested that electric power companies should take more efforts to reduce these costs in order to maintain the competitiveness of nuclear power in Japan. (author)

    Increased competition in wholesale power generation will allow electric utilities to use financial models to improve their decision making. This competition will result in the creation of electricity spot, futures, and forward markets, which will provide necessary information for utility executives to used advance financial tools, such as random walk models and options theory. These models will allow executives to place a value on risk. Once this value is known, executives can determine how best to manage that risk, whether by entering into financial transactions, adjusting their operational and planning decisions, or both

    In December 2005, the Hong Kong Government issued a 'Consultation Paper on Future Development of the Electricity Markets in Hong Kong: Stage II Consultation,' proposing a post-2008 regulatory regime upon the expiration of the existing regulatory contract between the Hong Kong Government and each of the two local electricity utilities. We assess the proposal using the criteria of safe, reliable, and environmentally friendly service at the lowest rates that will allow the utilities reasonable returns on their investments. We caution that if fully adopted, the highly risky proposal may lead to less-reliable service without the compensating benefits to the environment

    have examined a synergy effect between electricity and gas services in the US electric utility industry. They have compared electricity-specialized firms with diversified utility firms in their financial performance and corporate value. A problem of their study is that it has not empirically measured the operational performance of the electric utility firms. As an extension of the preceding study, this research investigates the operational performance of 104 US electric utility firms (1990-2004) by fully utilizing DEA (Data Envelopment Analysis). This study finds the three new policy implications. First, the synergy effect has not existed in the operational performance of diversified utility firms before and after the deregulation on the US electricity markets. Thus, core business concentration is more effective for electric utility firms than corporate diversification to enhance their operational performance under the current US deregulation policy. Second, the operational performance has had an increasing trend until 1996 and a decreasing trend after 1996. Thus, the US deregulation policy has been influential on their operational performance. Third, the enhancement in operational performance of electric utility firms has improved their financial performance. The improvement in financial performance has increased their corporate value. Thus, this study finds the business causality among operational performance, financial performance and corporate value in the US electric utility industry. - Research Highlights: →The synergy effect has not existed in the operational performance of diversified utility firms before and after the deregulation on the US electricity markets. →Core business concentration is more effective for electric utility firms than corporate diversification to enhance their operational performance under the current US deregulation policy. →The operational performance has had an increasing trend until 1996 and a decreasing trend after 1996.

    For any diagnostic system to be clinically useful, and go beyond description, it must provide an understanding that informs about aetiology and/or outcome. DSM-III and DSM-IV have provided reliability; the challenge for DSM-V and DSM-VI will be to provide validity. For DSM-V this will not be achieved. Believers in DSM-III and DSM-IV have impeded progress towards a valid classification system, so DSM-V needs to retain continuity with its predecessors to retain reliability and enhance research, but position itself to inform a valid diagnostic system by DSM-VI. This review examines the features of a diagnostic system and summarizes what is really known about mood disorders. The review also questions whether what are called mood disorders are primarily disorders of mood. Finally, it provides suggestions for DSM-VI.

  19. Consequence and impact of electric utility industry restructuring on transient stability and small-signal stability analysis

    2000-01-01

    The electric utility industry is undergoing unprecedented changes in its structure worldwide. With the advent of an open market environment and competition in the industry, and restructuring of the industry into separate generation, transmission, and distribution entities, new issues in power system operation and planning are inevitable. One of the major consequences of this new electric utility environment is the greater emphasis on reliability and secure operation of the power system. This paper examines the impact of restructuring on power system dynamic analysis. It specifically addresses issues related to transient stability analysis and small-signal stability analysis. Four major topics to examine the effect on the nature of studies conducted are considered. These topics are (1) system adequacy and security, (2) system modeling data requirements, (3) system protection and control, and (4) system restoration. The consequences and impact of each of these topics on the nature of the studies conducted are examined and discussed. The emphasis on greater reliability has led to a clearer enunciation of standards, measurements, and guides in some countries. These requirements will result in: (1) more measurements on existing systems, (2) rigorous analysis of transient stability and small-signal stability to determine operating limits and plan systems, (3) greater emphasis on studies to verify coordination and proper performance of protection and controls, and (4) development of a detailed plan for system restoration in the case of wide-spread outages

    The vision of an advanced information system is proposed to cope with the future social demand and business environmental change in electric utilities. At the large turning point such as drastic reconsideration of Electricity Utilities Industry Law, further improvement of efficiency and cost reduction are requested as well as business innovation such as proposal of a new business policy. For that purpose utilization of information and its technology is indispensable, and use of multimedia and common information in organization are the future direction for improving information basis. Consequently, free information networks without any limitation due to person and media are necessary, and the following are important: high-speed, high-frequency band, digital, easily connectable and multimedia transmission lines, and cost reduction and high reliability of networks. Based on innovation of information networks and the clear principle on advanced information system, development of new applications by multimedia technologies, diffusion of communication terminals, and promotion of standardization are essential. 60 refs., 30 figs., 5 tabs.

  1. The effects of rate of return and environmental regulations on the productivity performance in the US electric utility industry

    Durongkaveroj, P.

    1991-01-01

    Productivity growth in the US electric power industry has been declining since the late 1960's. Rate of return regulation and environmental regulations are hypothesized to adversely affect the productivity performance. Employing a Divisa index of the total factor productivity (TEP) an electric utility's performance is measured based on a profit maximization framework subject to both regulatory constraints. The empirical analysis attempts to analyze the effects of these regulations on the productivity growth employing data from privately-owned, fossil-fueled electric utilities. Results show a consistent decline in productivity growth over time averaging at 2% annually during 1977 and 1982, as well as the existence of regional differences in TFP growth among utilities. It shows positive and significant relationships between TFP growth and the rate of return, regulatory lag, the use of future test year, and deferred tax credit in the rate-making process. In the environmental case, results show that a stringent emission standard, using scrubbers for sulfur reduction and the utilization of aging power plants all contribute to the decline in productivity growth

    The publication of the DSM-5 means changes in the classification and recommendations for diagnosis of specific learning disabilities. Dyslexia and dyscalculia have been reintroduced into the DSM. Three specific learning disorders - impairment in reading, impairment in the written expression, and impairment in mathematics, described by subskills - are now part of the DSM-5. Three subcomponents of the reading disorder are expressly differentiated: word reading accuracy, reading rate, and fluency and reading comprehension. Impaired subskills of the specific learning disorder with impairment in written expression are spelling accuracy, grammar and punctuation accuracy, and clarity and organization of written expression. Four subskills are found in the mathematics disorder: number sense, memorization of arithmetic facts, accurate or fluent calculation, and accurate math reasoning. Each impaired academic domain and subskill should be recorded. A description of the severity degree was also included. The diagnosis is based on a variety of methods, including medical history, clinical interview, school report, teacher evaluation, rating scales, and psychometric tests. The IQ discrepancy criterion was abandoned, though that of age or class discrepancy criterion was retained. The application of a discrepancy is recommended by 1 to 2.5 SD. All three specific developmental disorders are common (prevalence 5 %-15 %), occur early during the first years of formal schooling, and persist into adulthood.

    Part 2 of this manual provides the electric utility engineer with detailed technical information on some of the major mechanical equipment used in the FGD system. The objectives of Part 2 are the following: to provide the electric utility engineer with information on equipment that may be unfamiliar to him, including ball mills, vacuum filters, and mist eliminators; and to identify the unique technique considerations imposed by an FGD system on more familiar electric utility equipment such as fans, gas dampers, piping, valves, and pumps. Part 3 provides an overview of the recommended procedures for evaluating proposals received from FGD system vendors. The objectives are to provide procedures for evaluating the technical aspects of proposals, and to provide procedures for determining the total costs of proposals considering both initial capital costs and annual operating and maintenance costs. The primary objective of Part 4 of this manual is to provide the utility engineer who has a special interest in the capabilities of FGDPRISM [Flue Gas Desulfurization PRocess Integration and Simulation Model] with more detailed discussions of its uses, requirements, and limitations. Part 5 is a case study in using this manual in the preparation of a purchase specification and in the evaluation of proposals received from vendors. The objectives are to demonstrate how the information contained in Parts 1 and 2 can be used to improve the technical content of an FGD system purchase specification; to demonstrate how the techniques presented in Part 3 can be used to evaluate proposals received in response to the purchase specification; and to illustrate how the FGDPRISM computer program can be used to establish design parameters for the specification and evaluate vendor designs.

    1990-09-01

    COMPLEAT takes its name, as an acronym, from Community-Oriented Model for Planning Least-Cost Energy Alternatives and Technologies. It is an electric utility planning model designed for use principally by publicly owned electric utilities and agencies serving such utilities. As a model, COMPLEAT is significantly more full-featured and complex than called out in APPA's original plan and proposal to DOE. The additional complexity grew out of a series of discussions early in the development schedule, in which it became clear to APPA staff and advisors that the simplicity characterizing the original plan, while highly desirable in terms of utility applications, was not achievable if practical utility problems were to be addressed. The project teams settled on Energy 20/20, an existing model developed by Dr. George Backus of Policy Assessment Associates, as the best candidate for the kinds of modifications and extensions that would be required. The remainder of the project effort was devoted to designing specific input data files, output files, and user screens and to writing and testing the compute programs that would properly implement the desired features around Energy 20/20 as a core program. This report presents in outline form, the features and user interface of COMPLEAT.

    Eating disorder diagnostic criteria were revised from the fourth to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV and -5, respectively). This study examines the impact of these revisions on rates of eating disorder diagnoses in treatment-seeking youth. Participants were 651 youth, ages 7-18 years, presenting to an outpatient eating disorders program who met criteria for a DSM-IV eating disorder diagnosis on intake. Patients completed well-validated semi-structured interviews to assess eating disorder psychopathology and psychiatric comorbidity. Participants were predominantly female (n = 588; 90.3%) with an average age of 15.28 years (SD = 2.21), mean percent of median Body Mass Index (mBMI) of 101.91 (SD = 31.73), and average duration of illness of 16.74 months (SD = 17.63). Cases of DSM-IV Eating Disorder Not Otherwise Specified (EDNOS), now most consistent with DSM-5 Other Specified Feeding or Eating Disorder, decreased from 47.6% to 39.0%, Anorexia Nervosa increased from 29.6% to 33.5%, and Bulimia Nervosa increased from 22.7% to 24.7%. Consistent with previous studies, and in keeping with the aims of the DSM-5 for eating disorders, the revised diagnostic criteria reduced cases of DSM-IV EDNOS and increased cases of specified eating disorders. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:578-581). © 2016 Wiley Periodicals, Inc.

    Background Diagnostic criteria for DSM-5 posttraumatic stress disorder (PTSD) are in many ways similar to DSM-IV criteria, raising the possibility that it might be possible to closely approximate DSM-5 diagnoses using DSM-IV symptoms. If so, the resulting transformation rules could be used to pool research data based on the two criteria sets. Methods The Pre-Post Deployment Study (PPDS) of the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) administered a blended 30-day DSM-IV and DSM-5 PTSD symptom assessment based on the civilian PTSD Checklist for DSM-IV (PCL-C) and the PTSD Checklist for DSM-5 (PCL-5). This assessment was completed by 9,193 soldiers from three US Army Brigade Combat Teams approximately three months after returning from Afghanistan. PCL-C items were used to operationalize conservative and broad approximations of DSM-5 PTSD diagnoses. The operating characteristics of these approximations were examined compared to diagnoses based on actual DSM-5 criteria. Results The estimated 30-day prevalence of DSM-5 PTSD based on conservative (4.3%) and broad (4.7%) approximations of DSM-5 criteria using DSM-IV symptom assessments were similar to estimates based on actual DSM-5 criteria (4.6%). Both approximations had excellent sensitivity (92.6-95.5%), specificity (99.6-99.9%), total classification accuracy (99.4-99.6%), and area under the receiver operating characteristic curve (0.96-0.98). Conclusions DSM-IV symptoms can be used to approximate DSM-5 diagnoses of PTSD among recently-deployed soldiers, making it possible to recode symptom-level data from earlier DSM-IV studies to draw inferences about DSM-5 PTSD. However, replication is needed in broader trauma-exposed samples to evaluate the external validity of this finding. PMID:25845710

  10. Determining optimum levels of DSM [demand-side management] as a supply-side resource

    International Nuclear Information System (INIS)

    Giles, S.H.; Mitchell, E.D.

    1990-01-01

    San Diego Gas and Electric Company (SDGE) recommends the evaluation of demand-side management as a supply-side resource. The advantages of concurrent economic analysis of DSM options with other traditional sources represents a significant improvement over analysis either before or after the development of a resource plan. The evaluation of utility-sponsored DSM programs that provide system benefits that include deferment of capacity additions and improvements in more efficient system operation should be evaluated side-by-side with traditional resources that provide similar benefits. The utility decision to either provide capital costs to construct a power plant or make demand payments for a power purchase is directly analogous to the decision to provide funding for a DSM program that would defer these same investments. Both types of decision represent utility control over investment decisions that allow the utility to provide reliable, low-cost power to its customers. SDGE has also had experience with using generation expansion scenarios to test different levels of pre-selected packages of DSM programs, attempting to evaluate the total costs of system expansion for each of the different packages. This method was fraught with problems, and the best information that could be gained was if the selection of DSM packages happened to bracket a lower cost scenario, when it could reasonably be assumed that both smaller and larger levels of DSM were not as cost effective as the intermediate level. However, in many cases the selection of DSM programs did not produce this result and the important question of whether individual DSM programs were worthwhile when evaluated individually, or whether the lowest cost scenario would be improved with more or less DSM, could not be answered

    Demand-side Management is a powerful strategy for modifying electric energy consumption patterns for the mutual benefit of consumers, the supplier and the economy as a whole Time-of-use pricing of electricity suggest a policy where the price is time-differentiated so as to reduce contribution to the system-peak which determines the capacity and investments of a power-system. This paper describes a case-study of net system benefit to an electric utility in India by offering time-of-use tariff to high voltage (HV) industrial consumers. The study shows that there is a potential of shifting about 19% H.V. Industrial loads from peak to off-peak hours thereby benefitting both, the consumers and the utility. 1 fig., 2 tabs

    The French law from February 10, 2000, about the modernization and development of the electric utility, has created new missions of public utility and foresees some compensation mechanisms for not handicapping the power operators in charge of these missions and for not creating competition distortions to their detriment on the European market. The author explains, first, the financial and economical stakes linked with these new missions. Then, he evokes the evolution of the energy context that has taken place between the 2. World war and the enforcement of the February 10, 2000 law, and he analyzes the systems foreseen for the power generation and distribution. For each public utility charge, the existing dispositions and those introduced by the law are analyzed and compared to the equivalent systems existing in other countries. Then, charge evaluation criteria and sharing rules and proposed. (J.S.)

    Detailed wind energy assessment from the available wind records, and evaluation of the application of wind energy systems to an existing electric utility were performed in an area known as the Texas Panhandle, on the Great Plains. The study area includes parts of Texas, eastern New Mexico, the Oklahoma Panhandle and southern Kansas. The region is shown to have uniformly distributed winds of relatively high velocity, with average wind power density of 0.53 kW/m/sup 2/ at 30 m height at Amarillo, Texas, a representative location. The annual period of calm is extremely low. Three separate compressed air storage systems with good potential were analyzed in detail, and two potential pumped-hydro facilities were identified and given preliminary consideration. Aquifer storage of compressed air is a promising possibility in the region.

    In this PowerPoint presentation, the author discusses the major advantages of laminated structures, for both the electric and telecommunication industries. The advantages include economy, quick delivery, climbing and field modifications, dimensional uniformity and stability. A series of pictures was displayed which showed the manufacturing process. Laminated structures have a proven history. They were developed in Europe in 1890, and introduced to the United States in 1934. Framing members were introduced in the late 1940s, while poles were introduced in 1963, two years ahead of steel poles. Some of the electrical utility applications include: (1) distribution structures, (2) transmission structures such as single-pole, phase over phase switch structures, tangent structures, and H-Frame construction. The applications for the telecommunication industry consist of joint use structures, such as electric and telecommunication, lighting and telecommunication, overhead telephone and wireless; mono-pole applications; three-pole Bell Towers; and tree poles. Examples of each type were shown. figs.

    The DSM-I is currently viewed as a psychoanalytic classification, and therefore unimportant. There are four reasons to challenge the belief that DSM-I was a psychoanalytic system. First, psychoanalysts were a minority on the committee that created DSM-I. Second, psychoanalysts of the time did not use DSM-I. Third, DSM-I was as infused with Kraepelinian concepts as it was with psychoanalytic concepts. Fourth, contemporary writers who commented on DSM-I did not perceive it as psychoanalytic. The first edition of the DSM arose from a blending of concepts from the Statistical Manual for the Use of Hospitals of Mental Diseases, the military psychiatric classifications developed during World War II, and the International Classification of Diseases (6th edition). As a consensual, clinically oriented classification, DSM-I was popular, leading to 20 printings and international recognition. From the perspective inherent in this paper, the continuities between classifications from the first half of the 20th century and the systems developed in the second half (e.g. DSM-III to DSM-5) become more visible.

    In recent years, demand side management (DSM) has emerged as an efficient utility planning strategy for reducing capacity shortages and improving system load factors. The Indian government is adopting various policies to implement DSM programs. DSM implementation involves a variety of interests with conflicting objectives, and a range of possible implementation strategies with varying implications for effectiveness, cost, feasibility, efficiency and stakeholder acceptance. This necessitates a critical comparison of the strategies to determine a preferred strategy or combination of strategies from each specific stakeholder's point of view. The present study evaluates DSM implementation strategies from a multiobjective perspective using the Analytic Hierarchy Process (AHP). Eight strategies and six criteria were considered. Forty utility, regulator, and consumer stakeholders were surveyed. The most highly ranked strategies involved creating dedicated funds and providing technical support to end users for effective implementation of DSM. (author)

  18. Preparing Canada's power systems for transition to the year 2000 : Y2K readiness assessment results for Canadian electric utility companies : first quarter 1999

    International Nuclear Information System (INIS)

    1999-01-01

    The effort made by Canadian electric utilities to minimize any power disruptions during the year 2000 (Y2K) transition is discussed and the state of readiness of the electric power industry with respect to the Y2K computer challenge is outlined. Canadian utilities started addressing Y2K issues several years ago, and today, reports show that every major electric utility in Canada is either on, or ahead of schedule to meet the industry established milestones for Y2K readiness. This report includes the assessment of all of Canada's large electric utilities, plus about 95 per cent of Canada's small distribution utilities. On average, the bulk electric utilities in Canada expect to be Y2K ready by mid-June 1999. This means that equipment and systems will operate properly for all dates including Y2K, or that there will be an operating strategy in place to mitigate the effects of any improper operations of equipment or systems. In terms of overall preparations for Y2K, Canada is ahead of the North American averages. Bulk electric utilities for non-nuclear generation are now 100 per cent complete in the inventory phase, 99 per cent complete in the assessment phase, and 91 per cent complete in the remediation/testing phase. For nuclear generation, completion rates are the same except for the remediation/testing phase which is 97 per cent complete. 1 tab., 21 figs

  19. Understanding the DSM-5: stasis and change.

    2018-03-01

    This paper aims to understand the DSM-5 through situating it within the context of the historical development of the DSM series. When one looks at the sets of diagnostic criteria, the DSM-5 is strikingly similar to the DSM-IV. I argue that at this level the DSM has become 'locked-in' and difficult to change. At the same time, at the structural, or conceptual, level there have been radical changes, for example in the definition of 'mental disorder', in the role of theory and of values, and in the abandonment of the multiaxial approach to diagnosis. The way that the DSM-5 was constructed means that the overall conceptual framework of the classification only barely constrains the sets of diagnostic criteria it contains.

    The interpretation of religion in DSM-III-R contains considerable negative bias and contributes to unfair stereotypes of religious persons. Particularly new religious movements and religious conversion are unfairly interpreted under the DSM-III-R heading, 'Dissociative Disorder Not Otherwise Specified'. It is suggested that a more balanced and respectful interpretation of religion is needed in DSM-III-R, since psychiatry through its official nomenclature should not contribute to social intolerance of religious nonconformity.

    Aspects of the recent report by the Ontario Electricity Conservation and Supply Task Force and Independent Market Operator which forecasts acute power supply shortages in Ontario, are discussed. Immediate action is recommended to avert the problem. The principal recommendation concerns the adoption of Demand Side Management as a tool to reduce the widening gap between supply and demand, citing supply shortage, imports, high prices, deregulated market and environmental concerns as the driving forces which push for the adoption of DSM. It is claimed that DSM, through its tools such as Demand/Load Response Programs and Time-of-Use rates has the capacity to create the necessary balance between supply and demand more efficiently, and in a more timely fashion than supply side management. The demand for adoption of DSM is justified on the basis of a careful examination of the magnitude and significance of each of the driving forces affecting the electricity supply in Ontario, as well as the benefits and techniques of DSM designed to manage power shortages. Energy Conservation and Efficiency and Demand/Load Response Programs are discussed as the principal DSM techniques, while Dynamic/Real Time Pricing, Time-of-Use Rates, Automated /Smart Metering, Web-based/Communication Systems, Reliability-based Programs, Market/Price-based programs, and Types of Load Control are described as the principal tools used by DSM. DSM program approaches and strategies are also reviewed, along with a brief list of successful examples of DSM applications. 3 figs

  8. The common denominator between DSM and power quality

    International Nuclear Information System (INIS)

    Porter, G.

    1993-01-01

    As utilities implement programs to push for energy efficiency, one of the results may be an increased population of end-uses that have a propensity to be sensitive to power delivery abnormalities. Some may view this as the price we have to pay for increasing the functionality of bulk 60 Hz power. Others may view this as a good reason to stay away from DSM. The utility industry must view this situation as an important element of their DSM planning and reflect the costs of mitigating potential power quality problems in the overall program. Power quality mitigation costs will not drastically add much to the total DSM bill, but the costs of poor power quality could definitely negate the positive benefits of new technologies. Failure to properly plan for the sensitivities of energy efficient equipment will be a major mistake considering the solutions are fairly well known. Proper understanding, education, design, and protection, using a systems approach to problem solving, will ensure that power quality problems won't force us to abandon beneficial efficiency improvement programs

    The safe and economic operation of nuclear power plants requires an appropriate infrastructure on the part of the operator as well as a high level of technical quality of the plants and of qualification of the personnel. Added to this are a variety of services rendered by specialist firms. The Bayernwerk utility, with plants of its own, has played a major role in the development of nuclear power in the Federal Republic of Germany. The importance of nuclear power to this firm is reflected in the pattern of its electricity sources and in the composition of its power plants. (orig.) [de

    This paper reports on Circulating Fluidized Bed (CFB) boiler technology which caught the attention of boiler users: first for its technical advantages of reduced air emissions and low grade fuel tolerance, then later for its problems in becoming a reliable process. Refractory longevity and fuel feed reliability plagued a number of new installations. The efficacy of CFB technology is now more assured with the recent success of Texas-New Mexico Power Company's 160 MWe CFB based units, the world's largest operating CFB boilers. Most of the more notable CFB development problems have been successfully addressed by these units. The TNP units have demonstrated that CFB's can reliable produce high capacity factors at low emission rates using a fuel that has traditionally hampered the operation of pulverized coal (PC) boilers and without the attendant problems associated with sulfur scrubbers required by PC boilers

    1998-10-01

    A century ago--in the year J.J. Thomson discovered the electron--electricity, gas and traction companies battled for markets, and corrupt city councils demanded their fair share of the take. One tycoon became so disgusted with the confusion and dishonesty that he decided to bribe the legislature to set up an honest, state-run regulatory agency that would bring order to chaos. But he was found out. The scandal set back the cause of regulation until 1907, the year in which the electric washing machine and the vacuum cleaner were invented. By then, electricity sales had septupled from 1897 levels, and three states had established utility regulation. In the coming decade, 1997 to 2007, the utility business could undergo similar dramatic change, but it will move toward less regulation and more competition during a period of slow growth. Management will have to work harder to achieve success, however, because much of the profits will have to come not from a growing market but from the pockets of competitors. By 2007, electricity will constitute a component of a larger energy and utility services industry that sells electricity, natural gas and possibly water, propane and telecommunications. Customized service will meet the needs of consumers of all sizes. The dominant firm in the industry, the virtual utility, may look more like a financial organization or a mass marketer than the traditional converter of raw material to energy. Emphasis on market-based pricing should lead to more efficient use of resources. If the process works right, the consumer wins.

    This study evaluated the relative distribution and inter-rater reliability of revised DSM-5 criteria for eating disorders in a residential treatment program. Consecutive adolescent and young adult females (N=150) admitted to a residential eating disorder treatment facility were assigned both DSM-IV and DSM-5 diagnoses by a clinician (n=14) via routine clinical interview and a research assessor (n=4) via structured interview. We compared the frequency of diagnostic assignments under each taxonomy and by type of assessor. We evaluated concordance between clinician and researcher assignment through inter-rater reliability kappa and percent agreement. Significantly fewer patients received either clinician or researcher diagnoses of a residual eating disorder under DSM-5 (clinician-12.0%; researcher-31.3%) versus DSM-IV (clinician-28.7%; researcher-59.3%), with the majority of reassigned DSM-IV residual cases reclassified as DSM-5 anorexia nervosa. Researcher and clinician diagnoses showed moderate inter-rater reliability under DSM-IV (κ=.48) and DSM-5 (κ=.57), though agreement for specific DSM-5 other specified feeding or eating disorder (OSFED) presentations was poor (κ=.05). DSM-5 revisions were associated with significantly less frequent residual eating disorder diagnoses, but not with reduced inter-rater reliability. Findings support specific dimensions of clinical utility for revised DSM-5 criteria for eating disorders. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    The fifth edition of Diagnostic and Statistical Manual, the DSM-5 appeared officially in May 2013 during the development of the 166th Annual Meetingof the American Psychiatric Association (APA) in San Francisco. The drafting process was long and complex; much of the debate became public so that the expectations were great. And it must be said that the new edition did not disappoint, as many changes were made in relation to their predecessors. In Chapter of Anxiety Disorders, which is reviewed in this article, the changes were significant. Obsessive-compulsive disorder and Stress-related disorders were excluded and new clinical pictures, such as separation anxiety disorder and selective mutism, were included. And took place was the long awaited split between panic disorder and agoraphobia, now two separate disorders.

    Most of the nuclear power plants in Japan have been shut down since the Fukushima accident in March 2011, without being permitted to restart after periodical inspections. Accordingly, thermal power generation significantly increased in FY 2011. In this paper the authors made a quantitative analysis on the unit costs of power generation and on the financial performance based on the financial reports of electric utilities. The average unit cost in FY 2011 rose to 11.6 JPY/kWh, 3 JPY/kWh higher than that in FY 2010, and will rise further to 12.6 JPY/kWh in FY 2012. The total retained profit of 8 utilities decreased by some 1 trillion JPY from FY 2010 to FY 2011 and will decrease further to 1 trillion JPY by the end of FY 2012, which is the lowest level in history. Clear decisions on energy policies and future power portfolio, as well as the restructuring of the electricity system in line with the rapid change in the power portfolio will be highly required for policy planners in Japan.

    1994-12-01

    During the winter of 1993, a number of U.S. electric utilities and some regional power pools discovered that current load exceeded generating capacity. Load restrictions followed, as entire regions-not just isolated utilities or even states-cut back. Was 1993 a typical, or simply a preview of the future If a preview, how did this shortage occur For a number of years, utilities, regulatory agencies, and power pools have been planning to add capacity at a much lower rate than the rate at which load has been growing. The National Electricity Reliability Council (NERC) has projected that eight of it's nine regions will have demand growth exceed capacity growth. The only region where capacity is growing faster is in the Texas Region. There are four reasons behind this shortage: excess capacity in the 1980's, disbelief in current forecasts, passage of the Clean Air act bringing stricter regulation on power plants, and the herd mentality where utilities have all delayed new plant construction.

    In India, there is growing interest among policymakers, planners, and regulators for aggressive electrification of passenger vehicles. For example, Piyush Goyal, the Minister of State for India’s Ministry of Coal, Power, New and Renewable Energy, announced an aspirational goal of converting all vehicle sales in India to battery electric vehicles (BEVs) by 2030 (Economic Times, 2016). In 2012, India has already announced the National Mission on Electric Mobility (NMEM) sets a countrywide goal of deploying 6 to 7 million hybrid and electric vehicles (EVs) by 2020 (DHI, 2012). A major policy motivation for transport electrification is to reduce India’s oil import dependency. The objective of this paper is to assess the effect of full electrification of vehicle sales in India by 2030 on the key stakeholders such as BEV owners, electric utilities, and the government. Specifically, we attempt to answer the following questions: (a) How does the total vehicle ownership cost of BEVs compare with the conventional vehicles? (b) What is the additional load due BEV charging? (c) What is the impact on the power sector investments, costs, and utility revenue? (d) How can smart BEV charging help renewable energy grid integration? (e) What is the impact on the crude oil imports? (f) What is the impact on the greenhouse gas (GHG) emissions?

    Controversy exists regarding the DSM-5 criteria for ASD. This study tested the psychometric properties of the DSM-5 model and determined how well it performed across different gender, IQ, and DSM-IV-TR sub-type, using clinically collected data on 227 subjects (median age = 3.95 years, majority had IQ > 70). DSM-5 was psychometrically superior to the DSM-IV-TR model (Comparative Fit Index of 0.970 vs 0.879, respectively). Measurement invariance revealed good model fit across gender and IQ. Younger children tended to meet fewer diagnostic criteria. Those with autistic disorder were more likely to meet social communication and repetitive behaviors criteria (p < .001) than those with PDD-NOS. DSM-5 is a robust model but will identify a different, albeit overlapping population of individuals compared to DSM-IV-TR.

    This article provides a brief overview of the development of the diagnostic criteria for eating disorders in DSM-IV. The process by which DSM-IV was developed is reviewed, including perspectives on what constitutes diagnostic validity and clinical utility, and their importance in assessing proposed changes in diagnostic criteria. The question of whether alterations in diagnostic criteria would clearly improve clinical utility was a major consideration in the DSM-IV process. Because of concerns that changes in diagnostic criteria would be disruptive and might entail loss of established knowledge, the DSM-IV Task Force assumed a generally conservative stance vis-à-vis change. The process of developing DSM-V is just beginning, and it is far from clear what alterations in diagnostic criteria for eating disorders will occur. However, the evolution of DSM-IV may provide a useful perspective on the development of DSM-V. (c) 2007 by Wiley Periodicals, Inc.

    The aim of the study was to compare the DSM-IV, DSM-5, and ICD-10 eating disorders (ED) nomenclatures to assess their value in the classification of pediatric eating disorders. We investigated the prevalence of the disorders in accordance with each system's diagnostic criteria, diagnostic concordance between the systems, and interrater reliability. Participants were 1062 children and adolescents assessed at intake to a specialist Eating Disorders Program (91.6% female, mean age 14.5 years, SD = 1.75). Measures were collected from routine intake assessments. DSM-5 categorization led to a lower prevalence of unspecified EDs when compared with DSM-IV. There was almost complete overlap for specified EDs. Kappa values indicated almost excellent agreement between the two coders on all three diagnostic systems, although there was higher interrater reliability for DSM-5 and ICD-10 when compared with DSM-IV. DSM-5 nomenclature is useful in classifying eating disorders in pediatric clinical samples. © 2018 Wiley Periodicals, Inc.

    The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was published in 2013, and its official Japanese version was published in 2014. The Japanese Government uses classifications from the 10th revision of the I nternational C lassification of D iseases (ICD-10) to categorize disorders and determine treatment fees. However, since the publication of the DSM-III, the use of the DSM system has become prevalent in research and educational settings in Japan. In addition to traditional psychiatry, both the ICD and the DSM are taught by many Japanese medical schools, and virtually all clinical research and trials refer to the DSM to define targeted disorders. Amid the current backdrop in which the reputation of the DSM-5 is being established, the editorial board of P sychiatry and C linical N eurosciences has asked Japanese experts across 12 specialties to examine the structure of the DSM-5, including the following categories: Neurodevelopmental Disorders, Schizophrenia Spectrum Disorders, Major Depression, Bipolar Disorders, Obsessive-Compulsive Disorders, Somatic Symptom Disorder, Eating Disorders, Substance-Related and Addictive Disorders, Gender Dysphoria, and Neurocognitive Disorders. Although opinions were only obtained from these selected experts, we believe that we have succeeded, to a certain extent, in presenting views that are representative of each specialty. © 2016 The Authors.

    2013-06-01

    The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) marks the first significant revision of the publication since the DSM-IV in 1994. Changes to the DSM were largely informed by advancements in neuroscience, clinical and public health need, and identified problems with the classification system and criteria put forth in the DSM-IV. Much of the decision-making was also driven by a desire to ensure better alignment with the International Classification of Diseases and its upcoming 11th edition (ICD-11). In this paper, we describe select revisions in the DSM-5, with an emphasis on changes projected to have the greatest clinical impact and those that demonstrate efforts to enhance international compatibility, including integration of cultural context with diagnostic criteria and changes that facilitate DSM-ICD harmonization. It is anticipated that this collaborative spirit between the American Psychiatric Association (APA) and the World Health Organization (WHO) will continue as the DSM-5 is updated further, bringing the field of psychiatry even closer to a singular, cohesive nosology.

    Full Text Available La próxima edición del DSM (DSM 5 aparecerá en Mayo de 2013. Los borradores publicados ya han generado diversas polémicas. Se ha criticado la posible inflación diagnóstica con una previsible epidemia de falsos positivos en nuevos diagnósticos como el "síndrome psicótico atenuado". La propuesta de otros nuevos diagnósticos como el «trastorno cognitivo leve", el "trastorno por atracones" o las "adicciones conductuales", entre otros, se suman a esta polémica. También se han criticado ciertos aspectos metodológicos del proceso, como la exigencia de confidencialidad y la falta de transparencia y los conflictos de intereses. El artículo repasa los antecedentes históricos del proceso DSM, con la revolución en la fiabilidad diagnóstica del DSM-III, los problemas de validez del DSM IV y las dudas que genera el DSM 5 en el supuesto cambio de "paradigma dimensional". Asimismo, se apunta a posibles vías futuras de solución, más allá del DSM 5, en el avance de las ciencias básicas del cerebro y de la conducta.

  5. The epic of the Swiss electric utilities: the entry into a new era of the Swiss history

    Remondeulaz, J.

    2010-01-01

    Until the 19 th century the only resources of Switzerland were wood and hydraulic energy. Their exploitation was adequate to produce heat and useful mechanical energy. The electrification of the country was introduced in the second half of the 19 th century in the form of hydropower in DC. The potential is very important, with a gigantic buffer constituted by the glaciers, estimated to be 50 TWh a year. Today, it is used at around 65-85% (for the time being, annual hydropower generation varies from 42.3 TWh in 2001 to only 32.6 in 2006). The standardization of power distribution in AC was realized during World War I: public and private lighting, space heating and hot water, mechanical power, drive propulsion system in replacement of gas, coal and vapour, e.g. with the electrification of the national railway network. Between 1875 and 1914 more than 1000 electric utilities have been established. The first law concerning hydropower was decided in 1916. During World War II the restrictions on fossil fuel import were an incentive for the development of new hydropower plants: it was the epic of the dams. The high voltage network (220 kV) was developed in order to enable interconnection with the neighbour countries France, Germany and Italy. Since 1958 this interconnection is established on the whole European level. Switzerland was entrusted with the frequency adjustment of the European network and the controlling of the exchanges in the framework of a special European agreement on electricity. From the Swiss point of view the international trade of electricity is very profitable: thanks to its accumulation lakes Switzerland can sell expensive peak load energy to whole Europe. Since the mid 50ies it was clear that the exploitation of all economically available hydropower would not be enough to cover the increasing demand of the country. A first experimental nuclear power plant was decided in 1961, built from 1962 on and turned into operation in 1968 (30 MW th and 6 MW el

    The Hawaii Demand-Side Management Resource Assessment was the fourth of seven projects in the Hawaii Energy Strategy (HES) program. HES was designed by the Department of Business, Economic Development, and Tourism (DBEDT) to produce an integrated energy strategy for the State of Hawaii. The purpose of Project 4 was to develop a comprehensive assessment of Hawaii`s demand-side management (DSM) resources. To meet this objective, the project was divided into two phases. The first phase included development of a DSM technology database and the identification of Hawaii commercial building characteristics through on-site audits. These Phase 1 products were then used in Phase 2 to identify expected energy impacts from DSM measures in typical residential and commercial buildings in Hawaii. The building energy simulation model DOE-2.1E was utilized to identify the DSM energy impacts. More detailed information on the typical buildings and the DOE-2.1E modeling effort is available in Reference Volume 1, ``Building Prototype Analysis``. In addition to the DOE-2.1E analysis, estimates of residential and commercial sector gas and electric DSM potential for the four counties of Honolulu, Hawaii, Maui, and Kauai through 2014 were forecasted by the new DBEDT DSM Assessment Model. Results from DBEDTs energy forecasting model, ENERGY 2020, were linked with results from DOE-2.1E building energy simulation runs and estimates of DSM measure impacts, costs, lifetime, and anticipated market penetration rates in the DBEDT DSM Model. Through its algorithms, estimates of DSM potential for each forecast year were developed. Using the load shape information from the DOE-2.1E simulation runs, estimates of electric peak demand impacts were developed. 10 figs., 55 tabs.

  7. Eating disorders in adolescents: how does the DSM-5 change the diagnosis?

    2015-11-01

    This study aimed to determine the changes in diagnosis that occur in making the transition from Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria in an adolescent medicine eating disorder program. During the months of September 2011 through December 2012, a data sheet was completed at the end of each new outpatient eating disorder evaluation listing the patient's gender, age, ethnicity, weight, height, DSM-IV diagnosis, and proposed DSM-5 diagnosis. Distributions were calculated using the Mann-Whitney and Wilcoxon rank sum analyses to determine differences between diagnostic groups. There were 309 patients evaluated during the 16-month period. DSM-IV diagnoses were as follows: anorexia nervosa, 81 patients (26.2%); bulimia nervosa, 29 patients (9.4%); binge eating disorder, 1 patient (0.3%); and eating disorder not otherwise specified (EDNOS), 198 patients (64.6%). By contrast, DSM-5 diagnoses were as follows: anorexia nervosa, 100 patients; atypical anorexia nervosa, 93 patients; avoidant/restrictive food intake disorder, 60 patients; bulimia nervosa, 29 patients; purging disorder, 18 patients; unspecified feeding or eating disorder, 4 patients; subthreshold bulimia nervosa, 2 patients; subthreshold binge eating disorder, 2 patients; and binge eating disorder, 1 patient. Almost two thirds (64.6%) of the 309 patients had a diagnosis of EDNOS based on the DSM-IV criteria. By contrast, only four patients had a diagnosis of unspecified feeding or eating disorder based on the DSM-5 criteria. These data demonstrate that the goal of providing more specific diagnoses for patients with eating disorders has been accomplished very successfully by the new DSM-5 criteria.

  8. Should the DSM V drop Asperger syndrome?

    Science.gov (United States)

    2010-09-01

    The DSM IV defines Asperger syndrome (AS) as a pervasive developmental (autistic spectrum) disorder characterized by social deficits and rigid focused interests in the absence of language impairment and cognitive delay. Since its inclusion in the DSM-IV, there has been a dramatic increase in its recognition both in children and adults. However, because studies have generally failed to demonstrate a clear distinction between AS and autism, some researchers have called for its elimination from the forthcoming DSM V. This report argues for a modification of its diagnostic criteria and its continued retention in the diagnostic manual.

    2013-01-01

    The rationale, research literature, and proposed changes to the dissociative disorders and conversion disorder in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) are presented. Dissociative identity disorder will include reference to possession as well as identity fragmentation, to make the disorder more applicable to culturally diverse situations. Dissociative amnesia will include dissociative fugue as a subtype, since fugue is a rare disorder that always involves amnesia but does not always include confused wandering or loss of personality identity. Depersonalization disorder will include derealization as well, since the two often co-occur. A dissociative subtype of posttraumatic stress disorder (PTSD), defined by the presence of depersonalization or derealization in addition to other PTSD symptoms, is being recommended, based upon new epidemiological and neuroimaging evidence linking it to an early life history of adversity and a combination of frontal activation and limbic inhibition. Conversion disorder (functional neurological symptom disorder) will likely remain with the somatic symptom disorders, despite considerable dissociative comorbidity.

    The thermophilic 'Geobacilli' are important sources of thermostable enzymes and other biotechnologically relevant macromolecules. The present work reports the high quality draft genome sequences of previously unsequenced type strains of Geobacillus uzenensis (DSM 23175 T ), G. thermocatenulatus (DSM 730 T ) and Parageobacillus galactosidasius (DSM 18751 T ). Phylogenomic analyses revealed that DSM 18751 T and DSM 23175 T represent later heterotypic synonyms of P. toebii and G. subterraneus , respectively, while DSM 730 T represents the type strain for the species G. thermocatenulatus . These genome sequences will contribute towards a deeper understanding of the ecological and biological diversity and the biotechnological exploitation of the 'geobacilli'.

    Hayley, Amie C; Stough, Con; Downey, Luke A

    2017-08-01

    Cannabis use disorder (CUD) is frequently associated with concurrent substance use and/or comorbid substance use disorders (SUDs); however there is little specificity with regard to commonly abused individual drug types/classes. This study therefore aimed to provide insight into the degree of these co-occurring relationships across several specific newer and older generation illicit and prescription drugs. 36,309 adults aged 18+ from wave 3 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III) were assessed. Weighted cross-tabulations and multivariable logistic regression analyses were used to evaluate comorbidity between current DSM-5 CUD, substance use and DSM-5 SUD. Current DSM-5 CUD is associated with greater lifetime use of all examined drug classes, and previous 12-month use of several newer-class illicit and prescription stimulant-based substances (all pDSM-5 CUD was similarly associated with increased incidence of a range of DSM-5 SUDs and was independently associated with concurrently reporting current DSM-5; sedative (Adjusted OR= 5.1, 95%CI 2.9-9.0), cocaine (AOR= 9.3, 95%CI 5.6-15.5), stimulant (AOR= 4.3, 95%CI 2.3-7.9), club drug (AOR= 16.1, 95%CI 6.3-40.8), opioid (AOR= 4.6, 95%CI 3.0-6.8) and alcohol-use disorder (AOR= 3.0, 95%CI 2.5-3.7); but not heroin or 'other' drug use disorder (both p>0.05). High comorbidity exists between DSM-5 CUD and many specific DSM-5 SUDs. Newer-class illicit and prescription stimulant-based drug use disorders are overrepresented among those with DSM-5 CUD. These findings underscore the need for tailored treatment programs for those presenting with DSM-5 CUD, and for greater treatment specification where poly-drug use is evident.

  14. A framework and review of customer outage costs: Integration and analysis of electric utility outage cost surveys

    2003-11-01

    A clear understanding of the monetary value that customers place on reliability and the factors that give rise to higher and lower values is an essential tool in determining investment in the grid. The recent National Transmission Grid Study recognizes the need for this information as one of growing importance for both public and private decision makers. In response, the U.S. Department of Energy has undertaken this study, as a first step toward addressing the current absence of consistent data needed to support better estimates of the economic value of electricity reliability. Twenty-four studies, conducted by eight electric utilities between 1989 and 2002 representing residential and commercial/industrial (small, medium and large) customer groups, were chosen for analysis. The studies cover virtually all of the Southeast, most of the western United States, including California, rural Washington and Oregon, and the Midwest south and east of Chicago. All variables were standardized to a consistent metric and dollar amounts were adjusted to the 2002 CPI. The data were then incorporated into a meta-database in which each outage scenario (e.g., the lost of electric service for one hour on a weekday summer afternoon) is treated as an independent case or record both to permit comparisons between outage characteristics and to increase the statistical power of analysis results. Unadjusted average outage costs and Tobit models that estimate customer damage functions are presented. The customer damage functions express customer outage costs for a given outage scenario and customer class as a function of location, time of day, consumption, and business type. One can use the damage functions to calculate outage costs for specific customer types. For example, using the customer damage functions, the cost experienced by an ''average'' customer resulting from a 1 hour summer afternoon outage is estimated to be approximately $3 for a residential customer, $1

  15. How many years should I be married: Long-term power contracts in the electric utility industry in Texas

    Levy Ferre, Alberto

    1998-12-01

    This dissertation deals with the effects of long-term power contracts in the electric utility in Texas on consumer welfare, investigating economic and legal aspects of price formation. The study focuses on the institutions---vertical integration and contractual arrangements---that govern the transactions between the different links in the electricity provision chain and its effects on retail electricity prices for residential, commercial and industrial customers. The main hypothesis is that long-term power contracts serve as an uncertainty reduction mechanism to the buyer by clearly defining the conditions of the exchange for a significant period of time. In turn, this reduction of uncertainty is compensated by a premium to the seller in the form of higher prices. It is found that long-term wholesale power contracts present varying levels of flexibility in the terms of the exchange that are directly translated into prices and bills, providing support to the main hypothesis. Control variables include the role of new technologies, degree of competition and population demographics. Each control variable has differing impacts of different customer classes, depending on their demand elasticity. The study poses several interesting policy implications. First, the institutions that will govern and supervise the functioning of the market have an important weight in its success. The results indicate that competition cannot be a policy objective in itself There is a balancing act between the additional needs of a functional market in terms of infrastructure, information and coordination, and the inefficiencies that occur for lack of consumer options. Second, all customers are not equal. Some customer classes have fewer alternatives than others do, their consumption patterns differ and their dependence on electricity varies. Therefore, a policy that treats all customer classes the same will produce an inferior outcome. Third, the relevant environment matters. Legislative

    1993-01-01

    Since the first regulated monopoly was established, there has been regulatory concern over the open-quotes level playing fieldclose quotes issue. This concern can be valid, but its character is relatively nebulous, and situational. Most recently, regulators have expressed their concern over the level playing field issue relative to demand side bidding, and demand side management (DSM) incentives regulation which provides utility shareholder returns for DSM initiatives. The playing field issues relative to DSM can be extensive. Utility ESCO subsidiaries are being formed, utility service contracts for HVAC equipment exist, and utilities have special access to customers and customer energy information. At the same time, all source bidding processes are required in some states allowing DSM projects to effectively displace supply side projects, customers must choose between utility DSM programs and ESCO offerings, and the list goes on

    The report describes the state of readiness of Canadian electric utility companies with respect to the Year 2000 computer challenge. It complements the North American Electric Reliability Council Report entitled `Preparing the Electric Power Systems of North America for Transition to the Year 2000: A Status and Work Plan.` Two surveys were employed to gather information for this report. The first, a detailed survey prepared by NERC, was forwarded to all major electric utilities that comprise the Bulk Electricity System in North America. CEA has removed the Canadian findings from the overall North American results, and has presented those findings in this report. The second was a shorter, more simplified study, conducted by CEA and Natural Resources Canada. Whereas small companies involved only in the distribution aspect of the electricity business were not asked to complete the NERC assessment, all Canadian electric utility companies were part of the shorter survey. Chapter 2 covers specifically the readiness status and project management for non-nuclear generation, nuclear generation, energy management systems, telecommunications systems, substation controls, system protection and distribution systems, business information systems, and small distribution companies.

    1991-01-01

    This research sought to address the relationship between self-concept and customer satisfaction: can customer satisfaction with a major electric utility be explained in terms of the self-reported, self-concept of the utility's managers The population to which the results of this study were generalized consisted of customer service managers in public electric utilities across the United States. In order to represent this population, a sample was selected consisting of customer service managers at a midwestern electric utility based in a large metropolitan area. Participants in this study were managers of four direct customer contact service organizations within six geographic division organizations. The methodology included comparisons of these four customer contact service organizations on twelve independent, self-concept variables and six customer satisfaction dependent variables using Analysis of Variance (ANOVA), Scheffe' tests, Chi-Square, and Stepwise multiple regression. The groups were found not to be significantly different and knowledge of the self-concept scores for managers will not increase the ability to predict customer satisfaction over no knowledge of self-concept scores.

    2017-01-01

    Aim of this study was to compare children diagnosed with Pervasive Developmental Disorder (PDD) according to DSM-IV-TR and DSM-5 diagnostic systems. One hundred fifty children aged between 3 and 15 years diagnosed with PDD by DSM-IV-TR were included. PDD symptoms were reviewed through psychiatric assessment based on DSM-IV-TR and DSM-5 criteria. Clinical severity was determined using Childhood Autism Rating Scale (CARS) and Autism Behavior Checklist (ABC). A statistically significant decrease (19.3 %) was detected in the diagnostic ratio with DSM-5. Age and symptom severity differed significantly between those who were and were not diagnosed with PDD using DSM-5. B4 criteria in DSM-5 was most common criterion. Results indicate that individuals diagnosed with PDD by DSM-IV-TR criteria may not be diagnosed using DSM-5 criteria.

    2016-12-01

    Different criteria for diagnosing posttraumatic stress disorder (PTSD) have been recommended by the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and the proposed 11th edition of the International Classification of Diseases (ICD-11). Although children are vulnerable to PTSD following disasters, little is known about whether these revised criteria are appropriate for preadolescents, as diagnostic revisions have been based primarily on adult research. This study investigated rates of PTSD using DSM-IV, DSM-5, and ICD-11 diagnostic criteria, and their associations with symptom severity, impairment, and PTSD risk factors. Children (7-11 years) exposed to Hurricanes Ike (n = 327) or Charley (n = 383) completed measures 8-9 months postdisaster. Using diagnostic algorithms for DSM-IV, DSM-5, and ICD-11, rates of 'probable' PTSD were calculated. Across samples, rates of PTSD were similar. However, there was low agreement across the diagnostic systems, with about a third overlap in identified cases. Children identified only by ICD-11 had higher 'core' symptom severity but lower impairment than children identified only by DSM-IV or DSM-5. ICD-11 was associated with more established risk factors for PTSD than was DSM-5. Findings revealed differences in PTSD diagnosis across major diagnostic systems for preadolescent children, with no clear advantage to any one system. Further research on developmentally sensitive PTSD criteria for preadolescent children is needed. © 2016 Association for Child and Adolescent Mental Health.

    The criteria for personality disorders in Section II of DSM-5 have not changed from those in DSM-IV. Therefore, the diagnosis of Section II narcissistic personality disorder (NPD) will perpetuate all of the well-enumerated shortcomings associated with the diagnosis since DSM-III. In this article, we will briefly review problems associated with Section II NPD and then discuss the evolution of a new model of personality disorder and the place in the model of pathological narcissism and NPD. The new model was intended to be the official approach to the diagnosis of personality pathology in DSM-5, but was ultimately placed as an alternative in Section III for further study. The new model is a categorical-dimensional hybrid based on the assessment of core elements of personality functioning and of pathological personality traits. The specific criteria for NPD were intended to rectify some of the shortcomings of the DSM-IV representation by acknowledging both grandiose and vulnerable aspects, overt and covert presentations, and the dimensionality of narcissism. In addition, criteria were assigned and diagnostic thresholds set based on empirical data. The Section III representation of narcissistic phenomena using dimensions of self and interpersonal functioning and relevant traits offers a significant improvement over Section II NPD.

    Woldeyesus, Tibebe Argaw

    Water supply constraints can significantly restrict electric power generation, and such constraints are expected to worsen with future climate change. The overarching goal of this thesis is to incorporate stochastic water-climate interactions into electricity portfolio models and evaluate various pathways for water savings in co-managed water-electric utilities. Colorado Springs Utilities (CSU) is used as a case study to explore the above issues. The thesis consists of three objectives: Characterize seasonality of water withdrawal intensity factors (WWIF) for electric power generation and develop a risk assessment framework due to water shortages; Incorporate water constraints into electricity portfolio models and evaluate the impact of varying capital investments (both power generation and cooling technologies) on water use and greenhouse gas emissions; Compare the unit cost and overall water savings from both water and electric sectors in co-managed utilities to facilitate overall water management. This thesis provided the first discovery and characterization of seasonality of WWIF with distinct summertime and wintertime variations of +/-17% compared to the power plant average (0.64gal/kwh) which itself is found to be significantly higher than the literature average (0.53gal/kwh). Both the streamflow and WWIF are found to be highly correlated with monthly average temperature (r-sq = 89%) and monthly precipitation (r-sq of 38%) enabling stochastic simulation of future WWIF under moderate climate change scenario. Future risk to electric power generation also showed the risk to be underestimated significantly when using either the literature average or the power plant average WWIF. Seasonal variation in WWIF along with seasonality in streamflow, electricity demand and other municipal water demands along with storage are shown to be important factors for more realistic risk estimation. The unlimited investment in power generation and/or cooling technologies is also

    Characterization of patients with both psychotic and mood symptoms, either concurrently or at different points during their illness, has always posed a nosological challenge and this is reflected in the poor reliability, low diagnostic stability, and questionable validity of DSM-IV Schizoaffective Disorder. The clinical reality of the frequent co-occurrence of psychosis and Mood Episodes has also resulted in over-utilization of a diagnostic category that was originally intended to only rarely be needed. In the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, an effort is made to improve reliability of this condition by providing more specific criteria and the concept of Schizoaffective Disorder shifts from an episode diagnosis in DSM-IV to a life-course of the illness in DSM-5. When psychotic symptoms occur exclusively during a Mood Episode, DSM-5 indicates that the diagnosis is the appropriate Mood Disorder with Psychotic Features, but when such a psychotic condition includes at least a two-week period of psychosis without prominent mood symptoms, the diagnosis may be either Schizoaffective Disorder or Schizophrenia. In the DSM-5, the diagnosis of Schizoaffective Disorder can be made only if full Mood Disorder episodes have been present for the majority of the total active and residual course of illness, from the onset of psychotic symptoms up until the current diagnosis. In earlier DSM versions the boundary between Schizophrenia and Schizoaffective Disorder was only qualitatively defined, leading to poor reliability. This change will provide a clearer separation between Schizophrenia with mood symptoms from Schizoaffective Disorder and will also likely reduce rates of diagnosis of Schizoaffective Disorder while increasing the stability of this diagnosis once made.

    Diagnostic reliability is essential for the science and practice of psychology, in part because reliability is necessary for validity. Recently, the DSM-5 field trials documented lower diagnostic reliability than past field trials and the general research literature, resulting in substantial criticism of the DSM-5 diagnostic criteria. Rather than indicating specific problems with DSM-5, however, the field trials may have revealed long-standing diagnostic issues that have been hidden due to a reliance on audio/video recordings for estimating reliability. We estimated the reliability of DSM-IV diagnoses using both the standard audio-recording method and the test-retest method used in the DSM-5 field trials, in which different clinicians conduct separate interviews. Psychiatric patients (N = 339) were diagnosed using the SCID-I/P; 218 were diagnosed a second time by an independent interviewer. Diagnostic reliability using the audio-recording method (N = 49) was "good" to "excellent" (M κ = .80) and comparable to the DSM-IV field trials estimates. Reliability using the test-retest method (N = 218) was "poor" to "fair" (M κ = .47) and similar to DSM-5 field-trials' estimates. Despite low test-retest diagnostic reliability, self-reported symptoms were highly stable. Moreover, there was no association between change in self-report and change in diagnostic status. These results demonstrate the influence of method on estimates of diagnostic reliability. (c) 2015 APA, all rights reserved).

    A recent meta-analysis found that DSM-III- and DSM-IV-defined traumas were associated with only slightly higher posttraumatic stress disorder (PTSD) symptoms than nontraumatic stressors. The current study is the first to examine whether DSM-5-defined traumas were associated with higher levels of PTSD than DSM-IV-defined traumas. Further, we examined theoretically relevant event characteristics to determine whether characteristics other than those outlined in the DSM could predict PTSD symptoms. One hundred six women who had experienced a trauma or significant stressor completed questionnaires assessing PTSD, depression, impairment, and event characteristics. Events were rated for whether they qualified as DSM-IV and DSM-5 trauma. There were no significant differences between DSM-IV-defined traumas and stressors. For DSM-5, effect sizes were slightly larger but still nonsignificant (except for significantly higher hyperarousal following traumas vs. stressors). Self-reported fear for one's life significantly predicted PTSD symptoms. Our results indicate that the current DSM-5 definition of trauma, although a slight improvement from DSM-IV, is not highly predictive of who develops PTSD symptoms. Our study also indicates the importance of individual perception of life threat in the prediction of PTSD. © 2017 S. Karger AG, Basel.

Desde la instalación de las primeras usinas eléctricas a fines del siglo diecinueve hasta los años treinta, el control de las empresas concesionarias estuvo a cargo de las autoridades municipales en ambos países. No obstante, la similar estructura de los sistemas eléctricos en Argentina y en Brasil, la participación del estado en la regulación de este sector estratégico para el desarrollo económico, se produjo en diferentes coyunturas. Como resultado de la crisis de 1930, el gobierno brasileño transformó los principios jurídicos que reglamentaban la gestión de la electricidad aplicando un criterio de regulación discrecional; mientras que el estado argentino intervino una década más tarde, nacionalizando las empresas. Mediante la comparación de las trayectorias regulatorias en ambos países, se identifican las divergencias en las políticas eléctricas y su impacto en los sistemas eléctricos en los años de la segunda posguerra.This article compares the evolution of electric utility regulation in Argentina and Brazil between 1890 and 1960. From the installation of electrical systems in the 19th century until the 1930s, electrical utility companies were controlled by the local authorities in both countries. The structure of electrical systems was similar in Argentina and Brazil, however the state regulation of electric utilities took place at different times. As a result of the 1930's crisis, the Brazilian government introduced a new legal approach by applying a discretionary regulation. On the other hand, the Argentinean government intervened one decade later, nationalizing the companies. By comparing both regulatory trajectories, the divergences as well as the effects of each policy on the electrical utility systems in the second postward period, are identified.

  20. Beyond the DSM: trends in psychiatry diagnoses

    Directory of Open Access Journals (Sweden)

    Andre Russowsky Brunoni

    Full Text Available Abstract Background: Although widely used in clinical practice and research, Diagnostic and Statistical Manual of Mental Disorders (DSM diagnoses have low validity: patients with different mental disorders can share similar symptoms, while those with the same diagnosis might have different symptoms. In fact, the DSM diagnostic system has been considered one of the main obstacles for further development of psychiatric research. Recently, it has been proposed that psychiatry nosology should be reframed according to a biologically-based etiology. Objectives: To review present and past endeavors of establishing an etiology-based nosology. Methods: Comprehensive review of articles on the topic. Results: From Hippocrates onwards, multiple attempts have been undertaken aiming to move etiology and nosology closer. The most recent efforts are represented by Developmental Psychopathology (DP and the Research Domain Criteria (RDoC, which presents an operational matrix recommended to be used in clinical research instead of the DSM diagnoses. Discussion: The DSM-based nosology is faulty. RDoC and DP might be interesting alternatives for an etiology-based nosology. However, while DP has already brought promising results, RDoC is a novel proposal, whose advantages and disadvantages should gradually be identified in the upcoming years.

    We compared DSM-IV criteria for major depression (MD) with clinically selected non-DSM criteria in their ability to represent clinical features of depression. We conducted network analyses of 19 DSM and non-DSM symptoms of MD assessed at personal interview in 5952 Han Chinese women meeting DSM-IV criteria for recurrent MD. We estimated an Ising model (the state-of-the-art network model for binary data), compared the centrality (interconnectedness) of DSM-IV and non-DSM symptoms, and investigated the community structure (symptoms strongly clustered together). The DSM and non-DSM criteria were intermingled within the same symptom network. In both the DSM-IV and non-DSM criteria sets, some symptoms were central (highly interconnected) while others were more peripheral. The mean centrality of the DSM and non-DSM criteria sets did not significantly differ. In at least two cases, non-DSM criteria were more central than symptomatically related DSM criteria: lowered libido vs. sleep and appetite changes, and hopelessness versus worthlessness. The overall network had three sub-clusters reflecting neurovegetative/mood symptoms, cognitive changes and anxiety/irritability. The sample were severely ill Han Chinese females limiting generalizability. Consistent with prior historical reviews, our results suggest that the DSM-IV criteria for MD reflect one possible sub-set of a larger pool of plausible depressive symptoms and signs. While the DSM criteria on average perform well, they are not unique and may not be optimal in their ability to describe the depressive syndrome. Copyright © 2017. Published by Elsevier B.V.

    The distinction between normality and psychopathology has long been subject to debate. DSM-III and DSM-IV provided a definition of mental disorder to help clinicians address this distinction. As part of the process of developing DSM-V, researchers have reviewed the concept of mental disorder and emphasized the need for additional work in this area. Here we review the DSM-IV definition of mental disorder and propose some changes. The approach taken here arguably takes a middle course through some of the relevant conceptual debates. We agree with the view that no definition perfectly specifies precise boundaries for the concept of mental/psychiatric disorder, but in line with a view that the nomenclature can improve over time, we aim here for a more scientifically valid and more clinically useful definition.

    We tested the inter-rater reliability and criterion-related validity of the DSM-IV-TR pedophilia diagnosis and proposed DSM-5 pedohebephilia diagnosis in a sample of 79 men who had committed child pornography offenses, contact sexual offenses against children, or who were referred because of concerns about whether they had a sexual interest in children. Participants were evaluated by two independent psychiatrists with an interview and questionnaire regarding demographic characteristics, sexual history, and self-reported sexual interests; they also completed phallometric and visual reaction time testing. Kappa was .59 for ever meeting DSM-IV-TR criteria for pedophilia and .52 for ever meeting the proposed DSM-5 criteria for pedohebephilia. Ever meeting DSM-IV-TR diagnosis was significantly related to self-reported index of sexual interest in children (highest AUC=.81, 95% CI=.70-.91, pDSM-5 "diagnosis" was similarly related to self-report (AUC=.84, 95% CI=.74-.94, pDSM-5 criteria, we believe these results suggest the revision of DSM-5 and development of ICD-11 could benefit from drawing on the current DSM-5 criteria, which are essentially the same as DSM-IV-TR except for a distinction between having a paraphilia (the interest) and a paraphilic disorder (the paraphilia plus clinically significant distress or impairment).

    Medically unexplained symptoms are considered 'somatoform disorders' in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). The introduction of this nosographic category has been helpful in drawing attention to a previously neglected area, but has not been successful in promoting an understanding of the disorders' biological basis and treatment implications, probably because of a series of diagnostic shortcomings. The newly proposed DSM-V diagnostic criteria try to overcome the limitations of the DSM-IV definition, which was organised centrally around the concept of medically unexplained symptoms, by emphasising the extent to which a patient's thoughts, feelings and behaviours concerning their somatic symptoms are disproportionate or excessive. This change is supported by a growing body of evidence showing that psychological and behavioural features play a major role in causing patient disability and maintaining high level of health care use. Pain disorders is the sub-category of DSM-IV somatoform disorders that most closely resembles fibromyalgia. Regardless of the diagnostic changes recently brought about by DSM-V, neuroimaging studies have identified important components of the mental processes associated with a DSM- IV diagnosis of pain disorder.

    The Hawaii Demand-Side Management Resource Assessment was the fourth of seven projects in the Hawaii Energy Strategy (HES) program. HES was designed by the Department of Business, Economic Development, and Tourism (DBEDT) to produce an integrated energy strategy for the State of Hawaii. The purpose of Project 4 was to develop a comprehensive assessment of Hawaii`s demand-side management (DSM) resources. To meet this objective, the project was divided into two phases. The first phase included development of a DSM technology database and the identification of Hawaii commercial building characteristics through on-site audits. These Phase 1 products were then used in Phase 2 to identify expected energy impacts from DSM measures in typical residential and commercial buildings in Hawaii. The building energy simulation model DOE-2.1E was utilized to identify the DSM energy impacts. More detailed information on the typical buildings and the DOE-2.1E modeling effort is available in Reference Volume 1, ``Building Prototype Analysis``. In addition to the DOE-2.1E analysis, estimates of residential and commercial sector gas and electric DSM potential for the four counties of Honolulu, Hawaii, Maui, and Kauai through 2014 were forecasted by the new DBEDT DSM Assessment Model. Results from DBEDTs energy forecasting model, ENERGY 2020, were linked with results from DOE-2.1E building energy simulation runs and estimates of DSM measure impacts, costs, lifetime, and anticipated market penetration rates in the DBEDT DSM Model. Through its algorithms, estimates of DSM potential for each forecast year were developed. Using the load shape information from the DOE-2.1E simulation runs, estimates of electric peak demand impacts were developed. Numerous tables and figures illustrating the technical potential for demand-side management are included.

    Electric utilities positively wrestle now with business diversification such as telecomunication, thermal supplying, urban planning to intensify the administrative foundation under relaxation for regulations. These businesses are yet small scale ones but are supposed to enlarge to the scale equivalent to the main business for a long period. Since the electric industry is a public utility enterprise and has fewer experiences to develop concrete diversifying strategy, this research was proceeded to determine the directions of diversification by analyzing management data or making hearing for well-diversified corporations such as fiber industry, private railway industry, and leasing industry. It was found from this study that diversification would have the possibility of plus for multiple managerial indeces such as profitability, growability and stability and that the diversification would be developed by using effectively the managerial resources. Then, the conditions on which electric utilities must consider when they enter into new businesses were arranged on the basis of this survey. 46 refs., 14 figs., 9 tabs.

    The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was published in May 2013. Autism spectrum disorder (ASD) has been structured for the three subtypes of pervasive developmental disorder (PDD), but the number of impairment in social and communication dimension is not stated. The subjects were 68 children who visited the Department of Psychology and Development at Nagoya City University Hospital for the first time between the ages of 6 and 15 years old. We retrospectively re-examined the subjects using DSM-IV-TR criteria and DSM-5 criteria with two rules (two of three and one of three on the social and communication dimension) and examined the concordance rate. Forty subjects were diagnosed with PDD, and 28 were not. The mean PDD subject age was 9.4 years, and mean IQ was 84.0 on the Wechsler Intelligence Scale for Children III or 62.7 on the Tanaka-Binet test. Twenty-seven (68%) of the PDD subjects were classified with ASD using DSM-5 criteria when the two of three rule was applied, while 32 (80%) were classified with ASD when the one of three rule was applied. All subjects without PDD were not diagnosed with ASD on DSM-5 criteria. DSM-5 criteria may exclude high functioning and older subjects from ASD because they tend to be atypical. The diagnostic procedure for DSM-5 criteria is ambiguous, especially in high functioning subjects and those diagnosed at an older age. © 2015 Japan Pediatric Society.

    The object of this study was to assess the prevalence and correlates of the DSM-IV diagnosis of hypochondriasis in a primary care setting. A large sample (N = 1456) of primary care users was given a structured interview to make diagnoses of mood, anxiety, and somatoform disorders and estimate levels of disability. The prevalence of hypochondriasis (DSM-IV) was about 3%. Patients with this disorder had higher levels of medically unexplained symptoms (abridged somatization) and were more impaired in their physical functioning than patients without the disorder. Of the various psychopathologies examined, major depressive syndromes were the most frequent among patients with hypochondriasis. Interestingly, unlike somatization disorder, hypochondriasis was not related to any demographic factor. Hypochondriasis is a relatively rare condition in primary care that is largely separable from somatization disorder but seems closely intertwined with the more severe depressive syndromes.

    2010-04-01

    Vaginal spasm has been considered the defining diagnostic characteristic of vaginismus for approximately 150 years. This remarkable consensus, based primarily on expert clinical opinion, is preserved in the DSM-IV-TR. The available empirical research, however, does not support this definition nor does it support the validity of the DSM-IV-TR distinction between vaginismus and dyspareunia. The small body of research concerning other possible ways or methods of diagnosing vaginismus is critically reviewed. Based on this review, it is proposed that the diagnoses of vaginismus and dyspareunia be collapsed into a single diagnostic entity called "genito-pelvic pain/penetration disorder." This diagnostic category is defined according to the following five dimensions: percentage success of vaginal penetration; pain with vaginal penetration; fear of vaginal penetration or of genito-pelvic pain during vaginal penetration; pelvic floor muscle dysfunction; medical co-morbidity.

  17. The DSM diagnostic criteria for dyspareunia.

    Binik, Yitzchak M

    2010-04-01

    The DSM-IV-TR attempted to create a unitary category of dyspareunia based on the criterion of genital pain that interfered with sexual intercourse. This classificatory emphasis of interference with intercourse is reviewed and evaluated from both theoretical and empirical points of view. Neither of these points of view was found to support the notion of dyspareunia as a unitary disorder or its inclusion in the DSM-V as a sexual dysfunction. It seems highly likely that there are different syndromes of dyspareunia and that what is currently termed "superficial dyspareunia" cannot be differentiated reliably from vaginismus. It is proposed that the diagnoses of vaginismus and dyspareunia be collapsed into a single diagnostic entity called genito-pelvic pain/penetration disorder. This diagnostic category is defined according to five dimensions: percentage success of vaginal penetration; pain with vaginal penetration; fear of vaginal penetration or of genito-pelvic pain during vaginal penetration; pelvic floor muscle dysfunction; medical co-morbidity.

    The recently published Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) includes several major revisions to substance use diagnoses. Studies have evaluated the impact of these changes among adult samples but research with adolescent samples is lacking. 525 adolescents (93% African American) awaiting primary care appointments in Baltimore, Maryland were recruited for a study evaluating a substance use screening instrument. Participants were assessed for DSM-5 nicotine, alcohol, and cannabis use disorder, DSM-IV alcohol and cannabis abuse, and DSM-IV dependence for all three substances during the past year using the modified Composite International Diagnostic Interview-2, Substance Abuse Module. Contingency tables examining DSM-5 vs. DSM-IV joint frequency distributions were examined for each substance. Diagnoses were more prevalent using DSM-5 criteria compared with DSM-IV for nicotine (4.0% vs. 2.7%), alcohol (4.6% vs. 3.8%), and cannabis (10.7% vs. 8.2%). Cohen's κ, Somers' d, and Cramer's V ranged from 0.70 to 0.99 for all three substances. Of the adolescents categorized as "diagnostic orphans" under DSM-IV, 7/16 (43.8%), 9/29 (31.0%), and 13/36 (36.1%) met criteria for DSM-5 disorder for nicotine, alcohol, and cannabis, respectively. Additionally, 5/17 (29.4%) and 1/21 (4.8%) adolescents who met criteria for DSM-IV abuse did not meet criteria for a DSM-5 diagnosis for alcohol and cannabis, respectively. Categorizing adolescents using DSM-5 criteria may result in diagnostic net widening-particularly for cannabis use disorders-by capturing adolescents who were considered diagnostic orphans using DSM-IV criteria. Future research examining the validity of DSM-5 substance use disorders with larger and more diverse adolescent samples is needed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Background Existing information on consequences of the DSM-5 revision for diagnosis of alcohol use disorders (AUD) has gaps, including missing information critical to understanding implications of the revision for clinical practice. Methods Data from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions were used to compare AUD severity, alcohol consumption and treatment, sociodemographic and health characteristics and psychiatric comorbidity among individuals with DSM-IV abuse versus DSM-5 moderate AUD and DSM-IV dependence versus DSM-5 severe AUD. For each pair of disorders, we additionally compared three mutually exclusive groups: individuals positive solely for the DSM-IV disorder, those positive solely for the DSM-5 disorder and those positive for both. Results Whereas 80.5% of individuals positive for DSM-IV dependence were positive for DSM-5 severe AUD, only 58.0% of those positive for abuse were positive for moderate AUD. The profiles of individuals with DSM-IV dependence and DSM-5 severe AUD were almost identical. The only significant (pDSM-5 moderate AUD and DSM-IV abuse differed substantially. The former endorsed more AUD criteria, had higher rates of physiological dependence, were less likely to be White and male, had lower incomes, were less likely to have private and more likely to have public health insurance, and had higher levels of comorbid anxiety disorders than the latter. Conclusions Similarities between the profiles of DSM-IV and DSM-5 AUD far outweigh differences; however, clinicians may face some changes with respect to appropriate screening and referral for cases at the milder end of the AUD severity spectrum, and the mechanisms through which these will be reimbursed may shift slightly from the private to public sector.

    How mental illnesses are defined has significant ramifications, given the substantial social and individual repercussions of these conditions. Using actor-network theory, I analyze how mental health professionals use the Diagnostic and Statistical Manual of Mental Disorders (DSM) in their work. Drawing on observations of a neuropsychological laboratory and interviews with 27 professionals (i.e., psychiatrists, psychologists), I investigate how the DSM is used in research, clinical, and institutional work. In research, the DSM influences study design and exclusion/inclusion criteria. In the clinic, the DSM influences how disorders are conceptualized and diagnosed. Institutionally, the DSM aligns the patient-professional encounter to insurance and pharmaceutical interests. I conclude that the DSM operates as multiple, context-specific taxonomies that pervasively influence professional practices, such that all possible actions must orient to DSM criteria, with professionals both a source and an object of institutionalized gaze. © American Sociological Association 2016.

    Full Text Available Dynamic spectrum management (DSM comprises a new set of techniques for multiuser power allocation and/or detection in digital subscriber line (DSL networks. At the Alcatel Research and Innovation Labs, we have recently developed a DSM test bed, which allows the performance of DSM algorithms to be evaluated in practice. With this test bed, we have evaluated the performance of a DSM level-1 algorithm known as iterative water-filling in an ADSL scenario. This paper describes the results of, on the one hand, the performance gains achieved with iterative water-filling, and, on the other hand, the nonstationary noise robustness of DSM-enabled ADSL modems. It will be shown that DSM trades off nonstationary noise robustness for performance improvements. A new bit swap procedure is then introduced to increase the noise robustness when applying DSM.

    Criteria for alcohol use disorders (AUD) in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) were intended to result in a similar prevalence of AUD as DSM-IV. We evaluated the prevalence of AUD using DSM-5 and DSM-IV criteria, and compared characteristics of patients who met criteria for: neither DSM-5 nor DSM-IV AUD, DSM-5 alone, DSM-IV alone, or both, among Veterans Administration (VA) outpatients in the Considering Healthier drinking Options In primary CarE (CHOICE) trial. VA primary care patients who reported frequent heavy drinking and enrolled in the CHOICE trial were interviewed at baseline using the DSM-IV Mini International Neuropsychiatric Interview for AUD, as well as questions about socio-demographics, mental health, alcohol craving, and substance use. We compared characteristics across 4 mutually exclusive groups based on DSM-5 and DSM-IV criteria. Of 304 participants, 13.8% met criteria for neither DSM-5 nor DSM-IV AUD; 12.8% met criteria for DSM-5 alone, and 73.0% met criteria for both DSM-IV and DSM-5. Only 1 patient (0.3%) met criteria for DSM-IV AUD alone. Patients meeting both DSM-5 and DSM-IV criteria had more negative drinking consequences, mental health symptoms and self-reported readiness to change compared with those meeting DSM-5 criteria alone or neither DSM-5 nor DSM-IV criteria. In this sample of primary care patients with frequent heavy drinking, DSM-5 identified 13% more patients with AUD than DSM-IV. This group had a lower mental health symptom burden and less self-reported readiness to change compared to those meeting criteria for both DSM-IV and DSM-5 AUD.

    Despite its importance historically and contemporarily, psychopathy is not recognized in the current Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revised (DSM-IV-TR). Its closest counterpart, antisocial personality disorder, includes strong representation of behavioral deviance symptoms but weak representation of affective-interpersonal features considered central to psychopathy. The current study evaluated the extent to which psychopathy and its distinctive facets, indexed by the Triarchic Psychopathy Measure, can be assessed effectively using traits from the dimensional model of personality pathology developed for DSM-5, operationalized by the Personality Inventory for DSM-5 (PID-5). Results indicate that (a) facets of psychopathy entailing impulsive externalization and callous aggression are well-represented by traits from the PID-5 considered relevant to antisocial personality disorder, and (b) the boldness facet of psychopathy can be effectively captured using additional PID-5 traits. These findings provide evidence that the dimensional model of personality pathology embodied in the PID-5 provides effective trait-based coverage of psychopathy and its facets.

  5. Addiction and dependence in DSM-V.

    O'Brien, Charles

    2011-05-01

    As preparations for the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM) are under way, this paper focuses upon changes proposed for the substance use disorders section. It briefly outlines the history behind the current nomenclature, and the selection of the term 'dependence' over 'addiction' in earlier versions of the DSM. The term 'dependence', while used in past decades to refer to uncontrolled drug-seeking behavior, has an alternative meaning--the physiological adaptation that occurs when medications acting on the central nervous system are ingested with rebound when the medication is abruptly discontinued. These dual meanings have led to confusion and may have propagated current clinical practices related to under-treatment of pain, as physicians fear creating an 'addiction' by prescribing opioids. In part to address this problem, a change proposed for DSM-V is to alter the chapter name to 'Addiction and Related Disorders', which will include disordered gambling. The specific substance use disorders may be referred to as 'alcohol use' or 'opioid use' disorders. The criteria for the disorders are likely to remain similar, with the exception of removal of the 'committing illegal acts' criterion and addition of a 'craving' criterion. The other major change relates to the elimination of the abuse/dependence dichotomy, given the lack of data supporting an intermediate stage. These changes are anticipated to improve clarification and diagnosis and treatment of substance use and related disorders. © 2010 The Author, Addiction © 2010 Society for the Study of Addiction.

  6. The DSM-5: Hyperbole, Hope or Hypothesis?

    Science.gov (United States)

    Berk, Michael

    2013-05-14

    The furore preceding the release of the new edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) is in contrast to the incremental changes to several diagnostic categories, which are derived from new research since its predecessor's birth in 1990. While many of these changes are indeed controversial, they do reflect the intrinsic ambiguity of the extant literature. Additionally, this may be a mirror of the frustration of the field's limited progress, especially given the false hopes at the dawn of the "decade of the brain". In the absence of a coherent pathophysiology, the DSM remains no more than a set of consensus based operationalized adjectives, albeit with some degree of reliability. It does not cleave nature at its joints, nor does it aim to, but neither does alternate systems. The largest problem with the DSM system is how it's used; sometimes too loosely by clinicians, and too rigidly by regulators, insurers, lawyers and at times researchers, who afford it reference and deference disproportionate to its overt acknowledged limitations.

    2013-12-01

    In May 2013 the American Psychiatric Association (APA) has released the latest and fifth edition of the diagnostic and statistical manual of mental disorders (DSM-5). Like its predecessor, the DSM-IV-TR, it will have considerable impact on the science of Psychiatry. The DSM-5 describes - actually available in English - the present medical knowledge about mental disorders. In the short run, German medical science and scientific medicolegal expertises will continue to rely on the German version of the DSM-IV-TR, however, they will be difficult to defend without bearing in mind the changes that DSM-5 brings about. This report discusses the transition from DSM-IV-TR to DSM-5 with regard to posttraumatic stress disorder (PTSD) and provides suggestions, how the criteria might be evaluated.

    The transition from DSM-IV to DSM-5 criteria for autism spectrum disorder (ASD) sparked considerable concern about the potential implications of these changes. This study was designed to address limitations of prior studies by prospectively examining the concordance of DSM-IV and final DSM-5 criteria on a consecutive sample of 439 children referred for autism diagnostic evaluations. Concordance and discordance were assessed using a consistent diagnostic battery. DSM-5 criteria demonstrated excellent overall specificity and good sensitivity relative to DSM-IV criteria. Sensitivity and specificity were strongest for children meeting DSM-IV criteria for autistic disorder, but poor for those meeting criteria for Asperger's disorder and pervasive developmental disorder. Higher IQ, older age, female sex, and less pronounced ASD symptoms were associated with greater discordance.

  10. DSM [demand-side management] opportunities in Alberta: An economist's perspective

    International Nuclear Information System (INIS)

    Woodward, R.S.

    1990-01-01

    In Alberta, utility companies are placing increasing attention on demand-side management (DSM) as one option for meeting future demand. Some basic economic principles are provided to yield a guideline on how much a utility should be spending on DSM initiatives. For the case of financial incentives to customers, it is shown that subsidies based on sound economic principles will enable the utility to charge lower overall rates to customers receiving the subsidy without raising other customers' rates. Moving outside of a well-understood market-based system and into a fully centralized planning approach to DSM eliminates a critical link between utilities and their customers. In Alberta, DSM measures appropriate in other regions will not be appropriate due to the province's unique supply and demand characteristics. Most of Alberta's electricity supply comes from low-cost coal-fired plants. On the demand-side, there is a significant concentration of large industrial and commercial consumers, notably in the oil and gas industry, and there is essentially no demand for electric heating in homes since natural gas is very abundant. The Alberta integrated power system currently operates at a load factor of ca 77%, reflecting the large industrial demand and the absence of a winter peaking effect associated with electrical heating requirements. A relatively small difference in embedded and incremental electricity supply costs means that utilities have little to spend on DSM programs. The identification of cost-effective DSM opportunities, most of which are likely to be found in the industrial sector, requires a considerable amount of detailed information on consumer behavior and close collaboration between utility and customer

  11. The impact of economic regulation on attempts to curb expense preference behavior: a micro-data analysis of CEO compensation schemes for electric utilities

    Mixon, F.G.; Upadhyaya, K.P.

    1999-01-01

    This study uses a large, micro data set to present evidence which suggests that owners of regulated electric utilities have little incentive to structure CEO compensation packages in an effort to curb potential expense preference behavior. Because such potential behavior occurs, or would occur, at no cost to the firm (or the firm's owners), little incentive exists to structure compensation schemes in a way that would curb such behavior (e.g. by compensating them with incentive bonus plans and stock options). The results presented here augment those which examine other industries (e.g. banking) in an effort to point out the relationships between ownership organization, political involvement and expense preference behavior.

    DSM-5 revised the diagnostic criteria for anorexia nervosa (AN) by eliminating the amenorrhea requirement, liberalizing weight and psychological criteria, and adding the formal diagnosis of "atypical AN" for individuals with AN psychological symptoms without low weight. We sought to determine whether bone density (BMD) is impaired in women diagnosed with AN using the new, more liberal, DSM-5 criteria. Cross-sectional study of 168 women, 18 - 45y: (1) AN by DSM-IV (DSM-IV AN) (n = 37), (2) AN by DSM-5 but not DSM-IV criteria (DSM-5 AN) (n = 33), (3) atypical AN (ATYPICAL AN) (n = 77), (4) healthy comparison group (HC) (n = 21). Measurements included dual energy X-ray absorptiometry, Eating Disorder Examination-Questionnaire, Eating Disorder Inventory-2, Hamilton Depression and Anxiety Rating Scales. BMD Z-score DSM-IV, 82% of DSM-5, and 69% of ATYPICAL. Mean Z-scores were comparably low in DSM-IV and DSM-5, intermediate in ATYPICAL, and highest in HC. Lack of prior low weight or amenorrhea was, but history of overweight/obesity was not, protective against bone loss. Mean lean mass and percent fat mass were significantly lower in all AN groups than HC. DSM-IV, DSM-5, and ATYPICAL had comparable psychopathology. Despite liberalizing diagnostic criteria, many women diagnosed with AN and atypical AN using DSM-5 criteria have low BMD. Presence or history of low weight and/or amenorrhea remain important indications for DXA. Loss of lean mass, in addition to fat mass, is present in all AN groups, and may contribute to low BMD. The deleterious effect of eating disorders on BMD extends beyond those with current low weight and amenorrhea. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:343-351). © 2016 Wiley Periodicals, Inc.

    This review covers the literature since the publication of DSM-IV on the diagnostic criteria for panic attacks (PAs) and panic disorder (PD). Specific recommendations are made based on the evidence available. In particular, slight changes are proposed for the wording of the diagnostic criteria for PAs to ease the differentiation between panic and surrounding anxiety; simplification and clarification of the operationalization of types of PAs (expected vs. unexpected) is proposed; and consideration is given to the value of PAs as a specifier for all DSM diagnoses and to the cultural validity of certain symptom profiles. In addition, slight changes are proposed for the wording of the diagnostic criteria to increase clarity and parsimony of the criteria. Finally, based on the available evidence, no changes are proposed with regard to the developmental expression of PAs or PD. This review presents a number of options and preliminary recommendations to be considered for DSM-V.

    ADA Environmental Solutions (ADA-ES) has successfully completed a research and development program granted by the Department of Energy National Energy Technology Laboratory (NETL) to develop a family of non-toxic flue gas conditioning agents to provide utilities and industries with a cost-effective means of complying with environmental regulations on particulate emissions and opacity. An extensive laboratory screening of potential additives was completed followed by full-scale trials at four utility power plants. The developed cohesivity additives have been demonstrated on a 175 MW utility boiler that exhibited poor collection of unburned carbon in the electrostatic precipitator. With cohesivity conditioning, opacity spiking caused by rapping reentrainment was reduced and total particulate emissions were reduced by more than 30%. Ammonia conditioning was also successful in reducing reentrainment on the same unit. Conditioned fly ash from the process is expected to be suitable for dry or wet disposal and for concrete admixture.

    Changes in autism diagnostic criteria found in DSM-5 may affect autism spectrum disorder (ASD) prevalence, research findings, diagnostic processes, and eligibility for clinical and other services. Using our published, total-population Korean prevalence data, we compute DSM-5 ASD and social communication disorder (SCD) prevalence and compare them with DSM-IV pervasive developmental disorder (PDD) prevalence estimates. We also describe individuals previously diagnosed with DSM-IV PDD when diagnoses change with DSM-5 criteria. The target population was all children from 7 to 12 years of age in a South Korean community (N = 55,266), those in regular and special education schools, and a disability registry. We used the Autism Spectrum Screening Questionnaire for systematic, multi-informant screening. Parents of screen-positive children were offered comprehensive assessments using standardized diagnostic procedures, including the Autism Diagnostic Interview-Revised and Autism Diagnostic Observation Schedule. Best-estimate clinical diagnoses were made using DSM-IV PDD and DSM-5 ASD and SCD criteria. DSM-5 ASD estimated prevalence was 2.20% (95% confidence interval = 1.77-3.64). Combined DSM-5 ASD and SCD prevalence was virtually the same as DSM-IV PDD prevalence (2.64%). Most children with autistic disorder (99%), Asperger disorder (92%), and PDD-NOS (63%) met DSM-5 ASD criteria, whereas 1%, 8%, and 32%, respectively, met SCD criteria. All remaining children (2%) had other psychopathology, principally attention-deficit/hyperactivity disorder and anxiety disorder. Our findings suggest that most individuals with a prior DSM-IV PDD meet DSM-5 diagnostic criteria for ASD and SCD. PDD, ASD or SCD; extant diagnostic criteria identify a large, clinically meaningful group of individuals and families who require evidence-based services.

  20. DSM-5: proposed changes to depressive disorders.

    Science.gov (United States)

    Wakefield, Jerome C

    2012-03-01

    The Diagnostic and Statistical Manual of Mental Disorders (DSM) is currently undergoing a revision that will lead to a fifth edition in 2013. Proposed changes for DSM-5 include the creation of several new categories of depressive disorder. Some nosologists have expressed concern that the proposed changes could yield many 'false-positive diagnoses' in which normal distress is mislabeled as a mental disorder. Such confusion of normal distress and mental disorder undermines the interpretability of clinical trials and etiological research, causes inefficient allocation of resources, and incurs risks of unnecessary treatment. To evaluate these concerns, I critically examine five proposed DSM-5 expansions in the scope of depressive and grief disorders: (1) a new mixed anxiety/depression category; (2) a new premenstrual dysphoric disorder category; (3) elimination of the major depression bereavement exclusion; (4) elimination of the adjustment disorder bereavement exclusion, thus allowing the diagnosis of subsyndromal depressive symptoms during bereavement as adjustment disorders; and (5) a new category of adjustment disorder related to bereavement for diagnosing pathological non-depressive grief. I examine each proposal's face validity and conceptual coherence as well as empirical support where relevant, with special attention to potential implications for false-positive diagnoses. I conclude that mixed anxiety/depression and premenstrual dysphoric disorder are needed categories, but are too broadly drawn and will yield substantial false positives; that the elimination of the bereavement exclusion is not supported by the evidence; and that the proposed elimination of the adjustment-disorder bereavement exclusion, as well as the new category of grief-related adjustment disorder, are inconsistent with recent grief research, which suggests that these proposals would massively pathologize normal grief responses.

    Although studies have examined the impact of changes made in DSM-5 on the estimated prevalence of substance use disorder (SUD) diagnoses, there is limited evidence concerning the reliability of DSM-5 SUDs. We evaluated the inter-observer reliability of four DSM-5 SUDs in a sample in which we had previously evaluated the reliability of DSM-IV diagnoses, allowing us to compare the two systems. Two different interviewers each assessed 173 subjects over a 2-week period using the Semi-Structured Assessment for Drug Dependence and Alcoholism (SSADDA). Using the percent agreement and kappa (κ) coefficient, we examined the reliability of DSM-5 lifetime alcohol, opioid, cocaine, and cannabis use disorders, which we compared to that of SSADDA-derived DSM-IV SUD diagnoses. We also assessed the effect of additional lifetime SUD and lifetime mood or anxiety disorder diagnoses on the reliability of the DSM-5 SUD diagnoses. Reliability was good to excellent for the four disorders, with κ values ranging from 0.65 to 0.94. Agreement was consistently lower for SUDs of mild severity than for moderate or severe disorders. DSM-5 SUD diagnoses showed greater reliability than DSM-IV diagnoses of abuse or dependence or dependence only. Co-occurring SUD and lifetime mood or anxiety disorders exerted a modest effect on the reliability of the DSM-5 SUD diagnoses. For alcohol, opioid, cocaine and cannabis use disorders, DSM-5 criteria and diagnoses are at least as reliable as those of DSM-IV. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    LAY ABSTRACT The Social Responsiveness Scale(SRS) is an autism rating scales in widespread use, with over 20 official foreign language translations. It has proven highly feasible for quantitative ascertainment of autistic social impairment in public health settings, however, little is known about the validity of the reinforcement in Asia populations or in references to DSM5. The current study aims to evaluate psychometric properties and cross-cultural aspects of the SRS-Korean version (K-SRS). Our results indicate that the K-SRS exhibits adequate reliability and validity for measuring Autism Spectrum Disorder (ASD) symptoms in Korean children with DSM IV PDD and DSM5 ASD. Our findings further suggest that it is difficult to distinguish Social Communication Disorder (SCD) from other child psychiatric conditions using the K-SRS. This is the first study to examine the relationship between the SRS subscales and DSM5 based clinical diagnosis. This study provides cross-cultural confirmation of the factor structure of ASD symptoms and traits measured by the SRS.

    This study relates to the schizotypal personality disorder (SPD) proposal of the upcoming fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) by investigating the construct validity of SPD as defined by DSM-IV in a large sample of patients from the Norwegian Network of Personality-Focused Treatment Programs (N = 2619), assessed by structured diagnostic interviews and the Longitudinal, Expert All Data standard. We investigated factor structure and psychometric properties of the SPD criteria, as well as co-occurrence patterns between SPD and other PDs. Thirty-six patients were diagnosed with SPD and 513 patients (21%) endorsed at least 2 schizotypal criteria. We found that 2 factors were specific for SPD, a cognitive-perceptual factor (ideas of reference, magical thinking, and unusual perceptual experiences) and an oddness factor (odd thinking and speech, constricted affect, and odd appearance or behavior). The criteria belonging to these factors had appropriate psychometric properties. The criteria of the cognitive-perceptual factor were more strongly associated with borderline personality disorder (PD) than with the other PDs. We did not find support for a consistent factor that reflected interpersonal problems. The criteria that used to be part of this factor (suspiciousness, lack of friends or confidants, and excessive social anxiety) performed poorly as specific SPD criteria. SPD was more strongly associated with antisocial PD and paranoid PD than with the other PDs. We suggest that ideas of reference should be included explicitly under the schizotypal facet of cognitive dysregulation in DSM-5, with less emphasis on the social phobic aspects of this feature. Furthermore, there should be more emphasis on the cognitive aspects of suspiciousness in SPD, and it should be considered to split up the affectivity criterion into constricted affect and inappropriate affect, with the latter type of affect being the expression of problems with

    This study was designed to estimate how many adults with DSM-5 Intermittent Explosive Disorder (IED) would also meet diagnostic criteria for Disruptive Mood Dysregulation Disorder (DMDD). This was done by examining how many individuals with IED would meet the DMDD criterion of being persistently angry in between impulsive aggressive outbursts. The first one-hundred study participants diagnosed with DSM-5 IED in our clinical research program were included in this study. Two questions were added to the IED module from the Structured Clinical Interview for DSM-5 Disorders (SCID) inquiring about the duration of anger in between impulsive aggressive outbursts in IED study participants. Data regarding aggression, impulsivity, anger expression, and related dysphoric variables were also collected. The proportion of time spent as angry in between impulsive aggressive outbursts was DSM-5 IED. Despite this, persistently-angry (i.e., angry >50% time in between outbursts) IED study participants displayed no differences from not-persistently-angry IED study participants in dysphoric and aggression/impulsivity related variables. These data indicate that inter-outburst anger in those with IED is relatively brief and that such individuals do not generally display the kind of persistent anger that is a diagnostic feature of DMDD.

    Soils play a crucial role in ecosystem functioning, and modelling its risk of degradation is fundamental, especially in the context of climate change. In this work we used continuous 3D soil information derived from digital soil mapping (DSM) approaches to map sediment erosion and deposition patterns due to rainfall. The test area covers the whole of mainland Scotland, excluding the Northern Islands. Soil profiles data were interpolated using a geo-statistical hybrid Generalised Additive Models method for a range of soil properties such as organic matter, texture, soil depth and peat presence. The same method was used to interpolate climatic data and management information. Remote sensing data were integrated in the process and land use data included. Information on grazing (sheep and deer) pressure was taken into account in the modelling. The uncertainty was accounted and propagated across the whole process. The Scottish test case highlights the differences in roles between mineral and organic soils with an assessment adapted to each of them. The results and intermediate steps were compared with available continental scale results. The results show the importance of the use of DSM approaches for modeling soils and ecosystem functions and assessing uncertainty propagation.

    In the framework of national policies which, since the end of the 70s, have had the target of making consumers rationally use the natural sources, in particular energy, and in the pursuit of environmental goals, the Governments and the utilities have driven several DSM (Demand-Side Management) actions, in many countries. The activities implemented by ENEL have included the analysis of the different components of the energy chain, from the primary sources to the final uses in industry, agriculture, residential and commercial buildings. This is in order to improve the energy efficiency by new electrotechnologies and more effective appliances. ENEL has carried out commercial initiatives by specific contractual agreements based on the marginal costs of the electric service. The paper explains ENEL's strategies and the actions implemented by the utility on DMS; the results in terms of energy efficiency, electric demand dynamics and of load curve changing are also explained. Finally the paper explores the DSM perspectives in the Italian future scenario, where energy companies will act in a more competitive market. (author)

    The latest definitions of autism spectrum disorders (ASDs) were specified in DSM-IV-TR in 2000. DSM-5 criteria are planned for 2013. Here, we estimated the prevalence of ASDs and autism according to DSM-IV-TR, clarified confusion concerning diagnostic criteria, and evaluated DSM-5 draft criteria for ASD posted by the American Psychiatry Association (APA) in February 2010. This was an epidemiological study of 5,484 eight-year-old children in Finland, 4,422 (81%) of them rated via the Autism Spectrum Screening Questionnaire by parents and/or teachers, and 110 examined by using a structured interview, semi-structured observation, IQ measurement, school-day observation, and patient records. Diagnoses were assigned according to DSM-IV-TR criteria and DSM-5 draft criteria in children with a full-scale IQ (FSIQ) ≥50. Patient records were evaluated in children with an FSIQ autism 4.1 in 1,000 according to DSM-IV-TR. Of the subjects with ASDs and autism, 65% and 61% were high-functioning (FSIQ ≥70), respectively. The prevalence of pervasive developmental disorder not otherwise specified was not estimated because of inconsistency in DSM-IV-TR criteria. DSM-5 draft criteria were shown to be less sensitive in regard to identification of subjects with ASDs, particularly those with Asperger's syndrome and some high-functioning subjects with autism. DSM-IV-TR helps with the definition of ASDs only up to a point. We suggest modifications to five details of DSM-5 draft criteria posted by the APA in February 2010. Completing revision of DSM criteria for ASDs is a challenging task. Copyright © 2011 American Academy of Child and Adolescent Psychiatry. Published by Elsevier Inc. All rights reserved.

    Generalized anxiety disorder (GAD) has undergone a series of substantial classificatory changes since its first inclusion in DSM-III. The majority of these revisions have been in response to its poor inter-rater reliability and concerns that it may lack diagnostic validity. This article provides options for the revision of the DSM-IV GAD criteria for DSM-V. First, searches were conducted to identify the evidence that previous DSM Work Groups relied upon when revising the DSM-III-R GAD and the overanxious disorder classifications. Second, the literature pertaining to the DSM-IV criteria for GAD was examined. The review presents a number of options to be considered for DSM-V. One option is for GAD to be re-labeled in DSM-V as generalized worry disorder. This would reflect its hallmark feature. Proposed revisions would result in a disorder that is characterized by excessive anxiety and worry generalized to a number of events or activities for 3 months or more. Worry acts as a cognitive coping strategy that manifests in avoidant behaviors. The reliability and validity of the proposed changes could be investigated in DSM-V validity tests and field trials.

    Prevalence of posttraumatic stress disorder (PTSD) defined according to the American Psychiatric Association’s Diagnostic and Statistical Manual fifth edition (DSM-5; 2013) and fourth edition (DSM-IV; 1994) was compared in a national sample of U.S. adults (N = 2,953) recruited from an online panel. Exposure to traumatic events, PTSD symptoms, and functional impairment were assessed online using a highly structured, self-administered survey. Traumatic event exposure using DSM-5 criteria was high (89.7%), and exposure to multiple traumatic event types was the norm. PTSD caseness was determined using Same Event (i.e., all symptom criteria met to the same event type) and Composite Event (i.e., symptom criteria met to a combination of event types) definitions. Lifetime, past-12-month, and past 6-month PTSD prevalence using the Same Event definition for DSM-5 was 8.3%, 4.7%, and 3.8% respectively. All 6 DSM-5 prevalence estimates were slightly lower than their DSM-IV counterparts, although only 2 of these differences were statistically significant. DSM-5 PTSD prevalence was higher among women than among men, and prevalence increased with greater traumatic event exposure. Major reasons individuals met DSM-IV criteria, but not DSM-5 criteria were the exclusion of nonaccidental, nonviolent deaths from Criterion A, and the new requirement of at least 1 active avoidance symptom.

    This report discusses the activities of organizations that seek to promote integrated resource planning and aggressive, cost-effective demand-side management by utilities. The activities of such groups -- here called energy efficiency advocacy groups (EEAGs) -- are examined in ten detailed am studies. Nine of the cases involve some form of interactive effort between investor-owned electric utilities and non-utility to develop policies, plans, or programs cooperatively. Many but not all of the interactive efforts examined are formal collaboratives. In addition, all ten cases include discussion of other EEAG activities, such as coalition-building, research, participation in statewide energy planning, and intervention in regulatory proceedings.

  13. Trends in Japan's power generation costs after the Fukushima Daiichi Nuclear Power Plant accident and their influence on finance of electric utilities

    Following the Fukushima Daiichi nuclear power plant accident, the nuclear reactors that were suspended for periodic inspections after the Fukushima accident were not permitted to resume operation, and nuclear power generation in Japan continued to decline. In this article, the authors quantitatively evaluated the effects on power generation costs of Japan's situation, using electric utilities financial reports up to FY 2011. We also analyzed the profitability of the Japanese electric industry, using the financial statements included in the reports, and quantitatively evaluated the effects of changes in power generation costs. The total cost of power generation has increased from 7.5 trillion yen in FY 2010 before the Fukushima accident to 9.6 trillion yen in FY 2011 and to 10.6 trillion yen in FY 2012. In particular, the fuel cost for thermal power generation rose sharply from 3.7 trillion yen in FY 2010 to 6.1 trillion yen in FY 2011 and 7.3 trillion yen in FY 2012, almost doubling in the two years from FY 2010 to 2012. The unit cost of power generation rose sharply from 8.6 yen/kWh in FY 2010 to 11.8 yen/kWh in FY 2011 and 13.5 yen/kWh in FY 2012. The unit cost is expected to rise even further in FY 2013 due to the weak yen. As the result not only Tokyo Electric Power Company, but also the other general electric utilities registered huge net losses. Their retained earnings (total of eight utilities) dropped by 2 trillion yen between FY 2010 and 2012. With increased thermal power generation, the risk of rising costs associated with changes in primary energy prices and exchange rates has increased drastically. For the stability of the electricity industry and the development of the Japanese economy, the government should clearly formulate a basic policy regarding the composition of power sources, and an effective plan both at home and abroad, and should develop a system that will be also to handle sudden changes in the composition of power sources.

    Full Text Available We present an accurate digital surface model (DSM derived from high-resolution Pleiades-1B 0.5 m panchromatic tri-stereo images, covering an area of 400 km2 over the Athens Metropolitan Area. Remote sensing and photogrammetry tools were applied, resulting in a 1 m × 1 m posting DSM over the study area. The accuracy of the produced DSM was evaluated against measured elevations by a differential Global Positioning System (d-GPS and a reference DSM provided by the National Cadaster and Mapping Agency S.A. Different combinations of stereo and tri-stereo images were used and tested on the quality of the produced DSM. Results revealed that the DSM produced by the tri-stereo analysis has a root mean square error (RMSE of 1.17 m in elevation, which lies within the best reported in the literature. On the other hand, DSMs derived by standard analysis of stereo-pairs from the same sensor were found to perform worse. Line profile data showed similar patterns between the reference and produced DSM. Pleiades tri-stereo high-quality DSM products have the necessary accuracy to support applications in the domains of urban planning, including climate change mitigation and adaptation, hydrological modelling, and natural hazards, being an important input for simulation models and morphological analysis at local scales.

    Mergers and acquisitions (M and A) are rapidly increasing among the U.S. electric utilities operators. This paper reports from among a large number of cases the mergers with district power distribution companies in England, and movements aiming at building a comprehensive energy corporation by using M and A with gas companies. The purpose of acquiring the British power distribution companies is to seek expanded earnings having become necessary due to little growth in power demand and intensified competition. This may be possible because the cap price is high in the cap price system in England, and can provide a large room for earning more profits. It is also an attempt of utilizing more effectively the experience of deregulation having been done ahead of America, such as introduction of unboundering and pooling systems. Four companies were under acquisition activities in even 1996 alone, and if prior acquisitions are added, actually half of British district power distribution companies have had been acquired. Merger of electric power companies with gas companies is the opening act of movements aimed at obtaining single-handed the oil business to become a comprehensive energy corporation. 4 refs., 14 tabs.

  6. Evaluating the Financial Vulnerability of a Major Electric Utility in the Southeastern U.S. to Drought under Climate Change and an Evolving Generation Mix.

    Kern, Jordan D; Characklis, Gregory W

    2017-08-01

    There is increasing recognition of the vulnerability of electric power systems to drought and the potential for both climate change and a shifting generation mix to alter this vulnerability. Nonetheless, the considerable research in this area has not been synthesized to inform electric utilities with respect to a key factor that influences their decisions about critical infrastructure: financial risk for shareholders. This study addresses this gap in knowledge by developing a systems framework for assessing the financial exposure of utilities to drought, with further consideration of the effects of climate change and a shifting generation mix. We then apply this framework to a major utility in the Southeastern U.S. Results suggest that extreme drought could cause profit shortfalls of more than $100 million if water temperature regulations are strictly enforced. However, even losses of this magnitude would not significantly impact returns for shareholders. This may inadvertently reduce pressure internally at utilities to incorporate drought vulnerability into long-term strategic planning, potentially leaving utilities and their customers at greater risk in the future.

  7. Effect of regulation on the rate of adoption of cost saving scale technology in the electric utility industry: a portfolio approach

    International Nuclear Information System (INIS)

    Scheraga, C.A.

    1984-01-01

    This study presents a new analytical framework for examining the relationship between regulation and the investment behavior of electric utilities. The particular kind of investment behavior considered is the adoption of new as well as innovative electrical generation technology. The technologies of interest are large scale coal and nuclear generation plants. The theoretical model used in this study differs from traditional approaches in its utilization of a behavioral framework of analysis. The responsiveness of utilities to the required rate of return demanded by stockholders is demonstrated using an augmented form of the standard Capital Asset Pricing Model. Regulation is viewed as affecting utility investment behavior through the effect of the actions of regulatory commissions on the required rate of return that utilities must earn on equity. The particular regulatory policies considered are modification of existing rate structure, automatic adjustment clauses, and required efficiency standards. These policies are of particular interest both because their effects have not been previously examined in detail, and because they are recommended for adoption in the Public Utility Regulatory Policies Act of 1978. It is demonstrated empirically that the above policies do affect the required rate of return for utilities and hence their innovative investment behavior

    This report is a legal study prepared to provide a review of the substantive and procedural laws of each regulatory jurisdiction that may affect implementation of the PURPA standards, and to summarize the current state of consideration and implementation of policies and rate designs similar or identical to the PURPA standards by state regulatory agencies and nonregulated utilities. This report is divided into three sections. The first section, the Introduction, summarizes the standards promulgated by PURPA and the results of the legal study. The second section, State Regulatory Law and Procedure, summarizes for each state or other ratemaking jurisdiction: (1) general constitutional and statutory provisions affecting utility rates and conditions of service; (2) specific laws or decisions affecting policy or rate design issues covered by PURPA standards; and (3) statutes and decisions governing administrative procedures, including judicial review. A chart showing actions taken on the policy and rate design issues addressed by PURPA is also included for each jurisdiction, and citations to relevant authorities are presented for each standard. State statutes or decisions that specifically define a state standard similar or identical to a PURPA standard, or that refer to one of the three PURPA objectives, are noted. The third section, Nonregulated Electric Utilities, summarizes information available on nonregulated utilities, i.e., publicly or cooperatively owned utilities which are specifically exempted from state regulation by state law.

    Heat pumps are seen as a promising technology for load management in the built environment, in combination with the smart grid concept. They can be coupled with thermal energy storage (TES) systems to shift electrical loads from high-peak to off-peak hours, thus serving as a powerful tool in demand-side management (DSM). This paper analyzes heat pumps with radiators or underfloor heating distribution systems coupled with TES with a view to showing how a heat pump system behaves and how it influences the building occupants' thermal comfort under a DSM strategy designed to flatten the shape of the electricity load curve by switching off the heat pump during peak hours (16:00–19:00). The reference scenario for the analysis was Northern Ireland (UK). The results showed that the heat pump is a good tool for the purposes of DSM, also thanks to the use of TES systems, in particular with heating distribution systems that have a low thermal inertia, e.g. radiators. It proved possible to achieve a good control of the indoor temperature, even if the heat pump was turned off for 3 h, and to reduce the electricity bill if a “time of use” tariff structure was adopted. -- Highlights: ► Heat pump heating systems with thermal energy storage are considered. ► System behavior is investigated during a DSM strategy for reducing peak energy demand. ► Heat pump heating systems demonstrate to be able to have an active role in DSM programs. ► A TES system must be coupled with the heat pump in presence of low thermal inertia heating distribution systems. ► Central role played by incentives schemes to promote this technology

    Many electric utilities operate energy efficiency incentive programs that encourage increased dissemination and use of energy-efficient (EE) products in their service territories. The programs can be segmented into three broad categories—downstream incentive programs target product end users, midstream programs target product distributors, and upstream programs target product manufacturers. Traditional downstream programs have had difficulty engaging Small Business/Small Portfolio (SBSP) audiences, and an opportunity exists to expand Commercial Midstream Incentive Programs (CMIPs) to reach this market segment instead.

    Development of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) has been ongoing since 1994, though official release will not occur for another 4 years. Potential revisions are being derived from multiple sources, including building on perceived limitations of DSM-IV; broad-based literature reviews; secondary and primary data analyses; and discussions between global members of the mental health community. The current focus on aligning DSM with the International Classification of Diseases-11 (ICD-11) speaks to the importance of creating a unified text that embraces cross-cutting issues of diagnostics, such as developmental, age-related, and cultural phenomena. International discourse is vital to this process and has been fostered by a National Institutes of Health-sponsored conference series on diagnosis-specific topics. From this series, the DSM-V Task Force developed the following set of revision principals to guide the efforts of the DSM-V Work Groups: grounding recommendations in empirical evidence; maintaining continuity with previous editions of DSM; removing a priori limitations on the amount of changes DSM-V may incur; and maintaining DSM's status as a living document. With work group formation complete, members are currently carrying out the research and revision recommendations proposed during the conference series. Ongoing activities include adding specialized advisors to each work group; completing literature reviews and planning data analyses; and forming study groups to discuss integration of cross-cutting issues (e.g., developmental lifespan factors; formation of diagnostic spectra). The road to DSM-V and ICD-11 has been challenging, but members continue to work diligently in their goal of constructing the most harmonious, scientifically sound, and clinically relevant DSM to date.

    Our study examines the Diagnostic and Statistical Manual-Fifth Edition (DSM-5) and Diagnostic and Statistical Manual-Fourth Edition, Text Revision (DSM-IV-TR) when applied concurrently against the best estimate clinical diagnoses for 110 children (5.1-19.6 years old) referred for diagnostic assessments of Autism Spectrum Disorder (ASD) in a Singaporean outpatient speciality clinic. DSM-IV-TR performed slightly better, yielding sensitivity of 0.946 and specificity of 0.889, compared to DSM-5 (sensitivity = 0.837; specificity = 0.833). When considering the ASD sub-categories, sensitivity ranged from 0.667 to 0.933, and specificity ranged from 0.900 to 0.975. More participants with a PDD-NOS best estimate clinical diagnosis (40%) were misclassified on DSM-5. Merits and weaknesses to both classification systems, and implications for access to services and policy changes are discussed.

    To examine the prevalence of social anxiety disorders (SAD) with (DSM-IV) and without (DSM-5) the person's own assessment that the fear was unreasonable, in a population sample of older adults. Further, to determine whether clinical and sociodemographic correlates of SAD differ depending on the criteria applied. Cross-sectional. General population in Gothenburg, Sweden. A random population-based sample of 75- and 85-year olds (N = 1200) without dementia. Psychiatric research nurses carried out a semi-structured psychiatric examination including the Comprehensive Psychopathological Rating Scale. DSM-IV SAD was diagnosed with the Mini International Neuropsychiatric Interview. SAD was diagnosed according to DSM-IV and DSM-5 criteria. The 6-month duration criterion in DSM-5 was not applied because of lack of information. Other assessments included the Global Assessment of Functioning (GAF), the Brief Scale for Anxiety (BSA), and the Montgomery Åsberg Depression Rating Scale (MADRS). The 1-month prevalence of SAD was 2.5% (N = 30) when the unreasonable fear criterion was defined in accordance with DSM-IV and 5.1% (N = 61) when the DSM-5 criterion was applied. Clinical correlates (GAF, MADRS, and BSA) were worse in SAD cases identified by either procedure compared with all others, and ratings for those reporting unreasonable fear suggested greater (albeit nonsignificant) overall psychopathology. Shifting the judgment of how reasonable the fear was, from the individual to the clinician, doubled the prevalence of SAD. This indicates that the DSM-5 version might increase prevalence rates of SAD in the general population. Further studies strictly applying all DSM-5 criteria are needed in order to confirm these findings. Copyright © 2016 American Association for Geriatric Psychiatry. Published by Elsevier Inc.

    2016-01-01

    As the revision process leading to DSM-5 began, the domain of personality disorder embodied the highest aspirations for major change. After an initial prototype-based proposal failed to gain acceptance, the Personality and Personality Disorders Work Group (P&PDWG) developed a hybrid model containing categorical and dimensional components. A clash of perspectives both within the P&PDWG and between the P&PDWG and DSM-5 oversight committees led to the rejection of this proposal from the main body of DSM-5. Major issues included conflicting ways of conceptualizing validation, differences of opinion from personality disorder experts outside the P&PDWG, divergent concepts of the magnitude of evidence needed to support substantial changes, and the disagreements about clinical utility of the hybrid model. Despite these setbacks, the 'Alternative DSM-5 Model of Personality Disorder' is presented in Section III of the DSM-5. Further research should clarify its performance relative to the DSM-IV criteria reprinted in the main DSM-5 text.

    Full Text Available When we compare the categories about alcohol, and substance-related disorders in DSM-IV and DSM-5, the new category, named addictive disorders is the most striking change. Only gambling disorder have been identified currently in this category. This may be the most remarkable change among the changes in the DSM-5. Because the expansion of the existing diagnostic criteria may cause the assessment of and lsquo;normal behavior' as a disorder. Additionally, withdrawal of caffeine and cannabis are defined in the DSM-5. Disorders collected under the title of substance-related disorders in the DSM-IV were collected under the name of substance-related and addictive disorders in the DSM-5. Specific criterias for substance abuse and substance addiction have been combined into the name of "substance use disorders". In substance abuse, "experienced legal problems" criteria was removed and "a strong desire or urge or craving for substance use" criteria has been introduced. Henceforth, substance abuse is defined as a mild form of substance use disorders in the DSM-5. A change in the prevalence of substance use disorders should be investigated by the new researches.

    The current study examined the latent factor structure of posttraumatic stress disorder (PTSD) based on DSM-5 criteria in a sample of participants (N = 374) recruited for studies on trauma and health. Confirmatory factor analyses (CFA) were used to compare the fit of the previous 3-factor DSM-IV model of PTSD to the 4-factor model specified in DSM-5 as well as to a competing 4-factor “dysphoria” model (Simms, Watson, & Doebbeling, 2002) and a 5-factor (Elhai et al., 2011) model of PTSD. Results indicated that the Elhai 5-factor model (re-experiencing, active avoidance, emotional numbing, dysphoric arousal, anxious arousal) provided the best fit to the data, although substantial support was demonstrated for the DSM-5 4-factor model. Low factor loadings were noted for two of the symptoms in the DSM-5 model (psychogenic amnesia and reckless/self-destructive behavior), which raises questions regarding the adequacy of fit of these symptoms with other core features of the disorder. Overall, the findings from the present research suggest the DSM-5 model of PTSD is a significant improvement over the previous DSM-IV model of PTSD. PMID:26366290

    Objective: The purpose of this study was to examine prevalences and concordances between Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), and Fifth Edition (DSM-5) substance use disorders (SUDs) in a newly completed U.S. epidemiologic survey. Method: The National Epidemiologic Survey on Alcohol and Related Conditions–III surveyed 36,309 civilian, noninstitutionalized adults. SUDs were assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule–5. Concordances between DSM-IV and DSM-5 disorders were assessed using kappa statistics. Results: Prevalences of past-year substance-specific DSM-5 disorders (2+ criteria) were modestly higher than those of DSM-IV dependence and abuse combined for alcohol, sedatives/tranquilizers, opioids, and heroin, but lower for cannabis, cocaine, and stimulants. Lifetime prevalences were lower under DSM-5. Prevalences were similar between moderate to severe (4+ criteria) DSM-5 disorders and dependence, whereas prevalences of DSM-5 disorders at 3+ criteria (DSM-5 [3+]) were higher, particularly for cannabis. Past-year concordances were excellent for DSM-IV dependence and abuse combined versus any DSM-5 and DSM-IV dependence versus DSM-5 moderate to severe disorders; lifetime concordances were fair to excellent. Past-year concordances between DSM-IV and DSM-5 (3+) were generally similar to or modestly higher than those with any DSM-5 disorder; lifetime concordances were mostly lower. Conclusions: Findings are consistent with those informing the development of DSM-5. Future research should examine differences in patterns between past-year and lifetime disorders, particularly for cannabis. Other questions warranting investigation include whether different combinations of the same numbers of criteria carry different clinical or nosologic implications, whether changes innosology yield changes in treatment demand, and whether changes in characteristics of individuals with DSM-5 SUDs

    This study sought to evaluate the construct validity of schizoid personality disorder (SZPD) by investigating a sample of 2,619 patients from the Norwegian Network of Personality-Focused Treatment Programs by a variety of statistical techniques. Nineteen patients (0.7%) reached the diagnostic threshold of SZPD. Results from the factor analyses indicated that SZPD consists of three factors: social detachment, withdrawal, and restricted affectivity/ anhedonia. Overall, internal consistency and diagnostic efficiency were poor and best for the criteria that belong to the social detachment factor. These findings pose serious questions about the clinical utility of SZPD as a diagnostic category. On the other hand, the three factors were in concordance with findings from previous studies and with the trait model for personality disorders in DSM-5, supporting the validity of SZPD as a dimensional construct. The authors recommend that SZPD should be deleted as a diagnostic category in future editions of DSM-5.

  2. Long-term consequences of selected competitive strategies during deregulation of the United States electric utility industry: System dynamics modeling and simulation

    Science.gov (United States)

    Khalil, Yehia Fahim

    Currently, U.S. investor-owned utilities (IOUs) are facing major reforms in their business environment similar to the airlines, telecommunications, banking, and insurance industries. As a result, IOUs are gearing up for fierce price competition in the power generation sector, and are vying for electricity customers outside their franchised service territories. Energy experts predict that some IOUs may suffer fatal financial setbacks (especially those with nuclear plants), while others may thrive under competition. Both federal and state energy regulators anticipate that it may take from five to ten years to complete the transition of America's electric utility industry from a regulated monopoly to a market-driven business. During this transition, utility executives are pursuing aggressive business strategies to confront the upcoming price wars. The most compelling strategies focus on cutting operation and maintenance (O&M) costs of power production, downsizing the work force, and signing bilateral energy agreements with large price-sensitive customers to retain their business. This research assesses the impact of the three pivotal strategies on financial performance of utilities during transition to open market competition. A system-dynamics-based management flight simulator has been developed to predict the dynamic performance of a hypothetical IOU organization preparing for market competition. The simulation results show that while the three business strategies lead to short-lived gains, they also produce unanticipated long-term consequences that adversely impact the organization's operating revenues. Generally, the designed flight simulator serves as a learning laboratory which allows management to test new strategies before implementation.

    2000-01-01

    Although hypochondriasis is generally believed to be a chronic and refractory disorder, relatively little is known about its natural history and course. Based on a cognitive/perceptual model of hypochondriasis, we hypothesized that the disorder would be more chronic in patients who both amplify benign bodily symptoms and tend to attribute them to disease. Thirty-eight patients with DSM hypochondriasis were assessed with a structured, diagnostic interview and self-report questionnaire. A logistic regression model containing sociodemographic characteristics and a 3-way interaction term composed of the tendency to amplify bodily sensations, the tendency to attribute common symptoms to disease, and somatization (all measured at inception) correctly classified the remission status of 81.6% of the patients at follow-up 4 years later. These results suggest that patients who somatize, who are amplifiers of bodily sensation, and those who tend to attribute ambiguous symptoms to disease have more chronic and more refractory hypochondriasis. It is the co-occurrence of these cognitive and perceptual characteristics, rather than their occurrence individually, which predicts the persistence of this disorder.

    These are the slides from this presentation. Lignocellulosic biomass is the most abundant, least expensive renewable natural biological resource for the production of biobased products and bioenergy is important for the sustainable development of human civilization in 21st century. For making the fermentable sugars from lignocellulosic biomass, a reduction in cellulase production cost, an improvement in cellulase performance, and an increase in sugar yields are all vital to reduce the processing costs of biorefineries. Improvements in specific cellulase activities for non-complexed cellulase mixtures can be implemented through cellulase engineering based on rational design or directed evolution for each cellulase component enzyme, as well as on the reconstitution of cellulase components. In this paper, we will provide DSM's efforts in cellulase research and developments and focus on limitations. Cellulase improvement strategies based on directed evolution using screening on relevant substrates, screening for higher thermal tolerance based on activity screening approaches such as continuous culture using insoluble cellulosic substrates as a powerful selection tool for enriching beneficial cellulase mutants from the large library. We will illustrate why and how thermostable cellulases are vital for economic delivery of bioproducts from cellulosic biomass using biochemical conversion approach.

    Aims To examine the diagnostic overlap in DSM-IV and DSM-5 alcohol use disorder (AUD) and determine the clinical correlates of changing diagnostic status across the two classification systems. Design DSM-IV and DSM-5 definitions of AUD were compared using cross-national community survey data. Setting Nine low-, middle- and high-income countries. Participants/Cases 31,367 respondents to surveys in the World Health Organization World Mental Health Survey Initiative. Measures Composite International Diagnostic Interview, version 3.0 was used to derive DSM-IV and DSM-5 lifetime diagnoses of AUD. Clinical characteristics, also assessed in the surveys, included lifetime DSM-IV anxiety, mood and drug use disorders, lifetime suicidal ideation, plan and attempt, general functional impairment and psychological distress. Findings Compared to DSM-IV AUD (12.3%, SE=0.3%), the DSM-5 definition yielded slightly lower prevalence estimates (10.8%, SE=0.2%). Almost one third (n=802) of all DSM-IV Abuse cases switched to sub-threshold according to DSM-5 and one quarter (n=467) of all DSM-IV diagnostic orphans switched to mild AUD according to DSM-5. New cases of DSM-5 AUD were largely similar to those who maintained their AUD across both classifications. Similarly, new DSM-5 non-cases were similar to those who were sub-threshold across both classifications. The exception to this was with regards to the prevalence of any lifetime drug use disorder. Conclusions In this large cross-national community sample, the prevalence of DSM-5 lifetime AUD was only slightly lower than the prevalence of DSM-IV lifetime AUD. Nonetheless there was considerable diagnostic switching, with a large number of people inconsistently identified across the two DSM classifications. PMID:27426631

    Pacific Gas and Electric Company (PG ampersand E) recently applied Demand-Side Management (DSM) evaluation techniques to photovoltaic (PV) technology to develop the concept of photovoltaics as a Demand-Side Management option (PV-DSM). The analysis demonstrated that PV-DSM has the potential to be economically attractive. Two criticisms in response to that analysis are that the assumptions of 25 year financing and a 25 year evaluation period are unrealistic. This paper responds to those criticisms and documents the mathematical relationships to calculate the value of PV-DSM from a customer's perspective. It demonstrates how regulatory and government agencies could implement policies to resolve both issues and speed PV commercialization

    Full Text Available Compared to the wide use of digital elevation model (DEM, digital surface model (DSM receives less attention because that it is composed by not only terrain surface, but also vegetations and man-made objects which are usually regarded as useless information. Nevertheless, these objects are useful for the identification of obstacles around an aerodrome. The primary objective of the study was to determine the applicability of DSM in obstacle clearance surveying of aerodrome. According to the requirements of obstacle clearance surveying at QT airport, aerial and satellite imagery were used to generate DSM, by means of photogrammetry, which was spatially analyzed with the hypothetical 3D obstacle limitation surfaces (OLS to identify the potential obstacles. Field surveying was then carried out to retrieve the accurate horizontal position and height of the obstacles. The results proved that the application of DSM could make considerable improvement in the efficiency of obstacle clearance surveying of aerodrome.

  10. The epistemological significance of possession entering the DSM.

    Science.gov (United States)

    Stephenson, Craig

    2015-09-01

    The discourse of the American Psychiatric Association's DSM reflects the inherently dialogic or contradictory nature of its stated mandate to demonstrate both 'nosological completeness' and cultural 'inclusiveness'. Psychiatry employs the dialogic discourse of the DSM in a one-sided, positivistic manner by identifying what it considers universal mental disease entities stripped of their cultural context. In 1992 the editors of the Diagnostic and Statistical Manual of Mental Disorders proposed to introduce possession into their revisions. A survey of the discussions about introducing 'possession' as a dissociative disorder to be listed in the DSM-IV indicates a missed epistemological break. Subsequently the editors of the DSM-5 politically 'recuperated' possession into its official discourse, without acknowledging the anarchic challenges that possession presents to psychiatry as a cultural practice. © The Author(s) 2015.

  14. Exploring efficacy of residential energy efficiency programs in Florida

    Science.gov (United States)

    Taylor, Nicholas Wade

    Electric utilities, government agencies, and private interests in the U.S. have committed and continue to invest substantial resources in the pursuit of energy efficiency and conservation through demand-side management (DSM) programs. Program investments, and the demand for impact evaluations that accompany them, are projected to grow in coming years due to increased pressure from state-level energy regulation, costs and challenges of building additional production capacity, fuel costs and potential carbon or renewable energy regulation. This dissertation provides detailed analyses of ex-post energy savings from energy efficiency programs in three key sectors of residential buildings: new, single-family, detached homes; retrofits to existing single-family, detached homes; and retrofits to existing multifamily housing units. Each of the energy efficiency programs analyzed resulted in statistically significant energy savings at the full program group level, yet savings for individual participants and participant subgroups were highly variable. Even though savings estimates were statistically greater than zero, those energy savings did not always meet expectations. Results also show that high variability in energy savings among participant groups or subgroups can negatively impact overall program performance and can undermine marketing efforts for future participation. Design, implementation, and continued support of conservation programs based solely on deemed or projected savings is inherently counter to the pursuit of meaningful energy conservation and reductions in greenhouse gas emissions. To fully understand and optimize program impacts, consistent and robust measurement and verification protocols must be instituted in the design phase and maintained over time. Furthermore, marketing for program participation must target those who have the greatest opportunity for savings.

    d'Angelo, P.; Reinartz, P.

    2012-07-01

    High resolution stereo satellite imagery is well suited for the creation of digital surface models (DSM). A system for highly automated and operational DSM and orthoimage generation based on CARTOSAT-1 imagery is presented, with emphasis on fully automated georeferencing. The proposed system processes level-1 stereo scenes using the rational polynomial coefficients (RPC) universal sensor model. The RPC are derived from orbit and attitude information and have a much lower accuracy than the ground resolution of approximately 2.5 m. In order to use the images for orthorectification or DSM generation, an affine RPC correction is required. In this paper, GCP are automatically derived from lower resolution reference datasets (Landsat ETM+ Geocover and SRTM DSM). The traditional method of collecting the lateral position from a reference image and interpolating the corresponding height from the DEM ignores the higher lateral accuracy of the SRTM dataset. Our method avoids this drawback by using a RPC correction based on DSM alignment, resulting in improved geolocation of both DSM and ortho images. Scene based method and a bundle block adjustment based correction are developed and evaluated for a test site covering the nothern part of Italy, for which 405 Cartosat-1 Stereopairs are available. Both methods are tested against independent ground truth. Checks against this ground truth indicate a lateral error of 10 meters.

    Demand-Side Management (DSM) is usually an utility (or sometimes governmental) activity designed to influence energy demand of customers (both level and load variation). It includes basic options like strategic conservation or load growth, peak clipping. Load shifting and fuel switching. Typical ways to realize DSM are direct load control, innovative tariffs, different types of campaign etc. Restructuring of utility in Finland and increased competition in electricity market have had dramatic influence on the DSM. Traditional ways are impossible due to the conflicting interests of generation, network and supply business and increased competition between different actors in the market. Costs and benefits of DSM are divided to different companies, and different type of utilities are interested only in those activities which are beneficial to them. On the other hand, due to the increased competition the suppliers are diversifying to different types of products and increasing number of customer services partly based on DSM are available. The aim of this project was to develop and assess methods for DSM and distribution automation planning from the utility point of view. The methods were also applied to case studies at utilities

    In the DSM-5, feeding disorders and eating disorders have been integrated into one single category. To review the rationale for changes in the criteria for feeding and eating disorders in DSM-5. The revised criteria were drafted and formulated by a DSM-5 workgroup. Next, professionals were given the opportunity to react to the proposed revisions by participating in several discussion rounds. The criteria for anorexia nervosa have been reworded and the amenorrhea criterion has been removed. The threshold for the diagnosis of bulimia nervosa has been lowered so that once-a-week binge eating and complementary behaviours are now sufficient for a patient to be diagnosed as having bulimia nervosa. Subtyping of bulimia nervosa has been removed. There are hardly any changes in the criteria for pica and rumination disorder. Two new official feeding and eating disorders have been introduced into DSM-5: avoidant/restrictive food intake disorder and binge eating disorder. The definition of and the criteria for feeding and eating disorders given in DSM-5 are an improvement on those used in dsm-iv and should help to reduce the eating disorders not otherwise specified (EDNOS).

    After participating in this activity, learners should be better able to:• Assess the changes in DSM-5 relative to earlier versions.• Evaluate the implications of the DSM-5 for practicing geriatric psychiatrists. About every 20 years, the American Psychiatric Association revises its official classification of mental disorders. The fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was published in 2013, prompting considerable commentary, debate, and criticism. This article briefly describes the process leading up to DSM-5 and the main changes from the previous version (DSM-IV) that would be of interest to a geriatric psychiatrist. The changes in the areas of schizophrenia, bipolar disorder, depressive disorders, and anxiety disorders have been many, but the majority of them are minor and unlikely to have major treatment implications. The classification of neurocognitive disorders, however, has seen a major revision and elaboration in comparison to DSM-IV; of special note is the introduction of "mild and major neurocognitive disorders," the latter equated with dementia. A common language has also been introduced for the criteria for the various etiological subtypes of neurocognitive disorders. All physicians treating patients with neurocognitive disorders should familiarize themselves with these criteria. Their use in research has the potential to harmonize the field.

  3. LINE-BASED REGISTRATION OF DSM AND HYPERSPECTRAL IMAGES

    Full Text Available Data fusion techniques require a good registration of all the used datasets. In remote sensing, images are usually geo-referenced using the GPS and IMU data. However, if more precise registration is required, image processing techniques can be employed. We propose a method for multi-modal image coregistration between hyperspectral images (HSI and digital surface models (DSM. The method is divided in three parts: object and line detection of the same object in HSI and DSM, line matching and determination of transformation parameters. Homogeneous coordinates are used to implement matching and adjustment of transformation parameters. The common object in HSI and DSM are building boundaries. They have apparent change in height and material, that can be detected in DSM and HSI, respectively. Thus, before the matching and transformation parameter computation, building outlines are detected and adjusted in HSI and DSM. We test the method on a HSI and two DSM, using extracted building outbounds and for comparison also extracted lines with a line detector. The results show that estimated building boundaries provide more line assignments, than using line detector.

    According to one of the diagnostic criteria of the dsm iv for conversion disorder there has to be a temporal relationship between psychological factors and the onset, or the worsening, of the symptoms. This criterion has been omitted in the dsm-5. Another criterion, namely that the symptoms are not produced intentionally, has also been abandoned. A new recommendation is that therapists should look for neurological symptoms that support the diagnosis. To investigate whether studies support the changes in the criteria. We searched literature using PubMed. When the symptoms first appear, trauma or stress in 37% of patients is of a physical rather than a psychological nature. Different forms of stress were found in equal proportions (20%) in patients with or without conversion disorder. There are no specific stressors, except possibly in patients with dysphonia. The percentages of childhood abuse vary widely, namely from 0 to 85%. The characteristic phenomenon of 'la belle indifference' occurs in only 3% of patients with conversion disorder versus only 2% of controls. Most of the 'positive' clinical tests for partial paralysis and sensory and gait disorders are highly specific. There are no reliable tests for distinguishing conversion disorder from simulation. The changes of the criteria are supported by recent studies.

    Psychiatric care providers should be trained to use current changes in the somatoform disorders criteria. New diagnostic criteria for Somatic Symptom disorders in the proposed DSM-V is discussed and compared with its older counterpart in DSM-IV. A new category called Somatic Syndrome Disorders is suggested. It includes new subcategories such as "Complex Somatic Symptom Disorder" (CSSD) and "Simple Somatic Symptom Disorder" (SSSD). Some of the subcategories of DSM-IV derived disorders are included in CSSD. While there are some changes in diagnostic criteria, there are concerns and limitations about the new classification needed to be more discussed before implementation. Functional somatic disturbance, the counterpart of converion disorder in DSM-IV, can be highly dependet on the developmental level of children. However, the role of developmental level needs to be considered.

    The aim of this study was to develop a functional fresh cream cheese with Bifidobacterium animalis subsp. lactis DSM 10140 or Lactobacillus reuteri DSM 20016 and prebiotics (inulin, FOS and lactulose). The research was divided into two steps: in vitro evaluation of the effects of prebiotic compounds; validation at laboratory level with production of functional cream mini-cheeses. Prebiotics showed a protective effect: B. animalis subsp. lactis DSM 10140 cultivability on Petri dishes was positively influenced by lactulose, whereas fructooligosaccharides (FOS) were the prebiotic compounds able to prolong Lb. reuteri DSM 20016 cultivability. At 30 °C, a prolongation of the death time (more than 300 days) was observed, while the controls showed death time values about 100 days. At 45 °C, death time values increased from 32.2 (control) to 33, 35, and 38 days in the samples added with FOS, inulin and lactulose, respectively. Lactulose and FOS were chosen to be added to cream mini-cheeses inoculated with B. animalis subsp. lactis DSM 10140 and Lb. reuteri DSM 20016, respectively; the proposed functional cream cheese resulted in a product with favourable conditions for the viability of both probiotics which maintained cultivable cells above the recommended level during 28 days of storage at 4 °C with good sensory characteristics.

    The purpose of this study was to compare the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) and the proposed Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) diagnostic criteria in terms of the number of cases of eating disorder not otherwise specified (EDNOS) and to see which diagnostic system can effectively capture variance in psychiatric symptoms in a Japanese sample. One thousand and twenty-nine women with an eating disorder (ED) participated in this study. Assessment methods included structured clinical interviews and administration of the Eating Attitudes Test and the Eating Disorder Inventory. Relaxing the diagnostic criteria for anorexia nervosa and bulimia nervosa and recognizing binge ED decreased the proportion of EDNOS (from 45.1% to 26.1%). The DSM-5 categorization of patients was better able to capture variance in psychopathology scales. The proposed revisions to EDs in the DSM-5 partially reduced reliance on EDNOS. The DSM-5 may differentiate ED groups more effectively than the DSM-IV. Copyright © 2012 John Wiley & Sons, Ltd and Eating Disorders Association.

    The global economy has grown rapidly over the past decade with a commensurate growth in the demand for electricity services that has increased a country's vulnerability to energy supply disruptions. Increasing need of reliable and affordable electricity supply is a challenge which is before every Asia Pacific Partnership (APP) country. Collaboration between APP members has been extremely fruitful in identifying potential efficiency upgrades and implementing clean technology in the supply side of the power sector as well established the beginnings of collaboration. However, significantly more effort needs to be focused on demand side potential in each country. Demand side management or DSM in this case is a policy measure that promotes energy efficiency as an alternative to increasing electricity supply. It uses financial or other incentives to slow demand growth on condition that the incremental cost needed is less than the cost of increasing supply. Such DSM measures provide an alternative to building power supply capacity The type of financial incentives comprise of rebates (subsidies), tax exemptions, reduced interest loans, etc. Other approaches include the utilization of a cap and trade scheme to foster energy efficiency projects by creating a market where savings are valued. Under this scheme, greenhouse gas (GHG) emissions associated with the production of electricity are capped and electricity retailers are required to meet the target partially or entirely through energy efficiency activities. Implementation of DSM projects is very much in the early stages in several of the APP countries or localized to a regional part of the country. The purpose of this project is to review the different types of DSM programs experienced by APP countries and to estimate the overall future potential for cost-effective demand-side efficiency improvements in buildings sectors in the 7 APP countries through the year 2030. Overall, the savings potential is estimated to be

    Substantial revisions to the DSM-IV criteria for autism spectrum disorders (ASDs) have been proposed in efforts to increase diagnostic sensitivity and specificity. This study evaluated the proposed DSM-5 criteria for the single diagnostic category of autism spectrum disorder in children with DSM-IV diagnoses of pervasive developmental disorders (PDDs) and non-PDD diagnoses. Three data sets included 4,453 children with DSM-IV clinical PDD diagnoses and 690 with non-PDD diagnoses (e.g., language disorder). Items from a parent report measure of ASD symptoms (Autism Diagnostic Interview-Revised) and clinical observation instrument (Autism Diagnostic Observation Schedule) were matched to DSM-5 criteria and used to evaluate the sensitivity and specificity of the proposed DSM-5 criteria and current DSM-IV criteria when compared with clinical diagnoses. Based on just parent data, the proposed DSM-5 criteria identified 91% of children with clinical DSM-IV PDD diagnoses. Sensitivity remained high in specific subgroups, including girls and children under 4. The specificity of DSM-5 ASD was 0.53 overall, while the specificity of DSM-IV ranged from 0.24, for clinically diagnosed PDD not otherwise specified (PDD-NOS), to 0.53, for autistic disorder. When data were required from both parent and clinical observation, the specificity of the DSM-5 criteria increased to 0.63. These results suggest that most children with DSM-IV PDD diagnoses would remain eligible for an ASD diagnosis under the proposed DSM-5 criteria. Compared with the DSM-IV criteria for Asperger's disorder and PDD-NOS, the DSM-5 ASD criteria have greater specificity, particularly when abnormalities are evident from both parents and clinical observation.

    As an approach to manage power demand-side resources, DSM plays an important role in electric power system. Though DSM was introduced into China in the early 1990s, its benefits have been underutilized. Using literature study, interview methods and three data sources, this paper examines the likely impacts of China's on-going power sector reform on its DSM. It finds that the major constraints to DSM in China are the insufficient and improper market-based DSM mechanism, grid companies’ low motivations for DSM due to their traditional business model, the underdeveloped energy service industry, and electricity end-users’ low motivation for DSM. China's on-going power sector reform will change power transmission and distribution pricing and grid companies’ business model and introduce competition into retail-side. Drawing on these findings, it is concluded that the likely impacts of the new reform on DSM are: governments may attach more importance to DSM; grid companies may have more motivations for DSM investment; electricity end-users’ motivations for DSM may be both enhanced and dampened; electricity retailers’ motivations for DSM may be dampened; demand response application may be enhanced, and more DSM business models may be developed. Finally, policy implications are provided. - Highlights: • Mechanism of and constraints to DSM in China are examined. • China’s on-going power sector reform is overviewed. • DSM is likely to be enhanced under China's on-going power sector reform. • Policy implications are provided.

    Background. DSM-5 revisions have been criticized in the popular press for overpathologizing normative eating patterns—particularly among individuals with obesity. To evaluate the evidence for this and other DSM-5 critiques, we compared the point prevalence and interrater reliability of DSM-IV versus DSM-5 eating disorders (EDs) among adults seeking weight-loss treatment. Method. Clinicians (n = 2) assigned DSM-IV and DSM-5 ED diagnoses to 100 participants via routine clinical interview. Research assessors (n = 3) independently conferred ED diagnoses via Structured Clinical Interview for DSM-IV and a DSM-5 checklist. Results. Research assessors diagnosed a similar proportion of participants with EDs under DSM-IV (29%) versus DSM-5 (32%). DSM-5 research diagnoses included binge eating disorder (9%), bulimia nervosa (2%), subthreshold binge eating disorder (5%), subthreshold bulimia nervosa (2%), purging disorder (1%), night eating syndrome (6%), and other (7%). Interrater reliability between clinicians and research assessors was “substantial” for both DSM-IV (κ = 0.64, 84% agreement) and DSM-5 (κ = 0.63, 83% agreement). Conclusion. DSM-5 ED criteria can be reliably applied in an obesity treatment setting and appear to yield an overall ED point prevalence comparable to DSM-IV. PMID:25057413

    This article provides a focused review of the literature on compulsive hoarding and presents a number of options and preliminary recommendations to be considered for DSM-V. In DSM-IV-TR, hoarding is listed as one of the diagnostic criteria for obsessive-compulsive personality disorder (OCPD). According to DSM-IV-TR, when hoarding is extreme, clinicians should consider a diagnosis of obsessive-compulsive disorder (OCD) and may diagnose both OCPD and OCD if the criteria for both are met. However, compulsive hoarding seems to frequently be independent from other neurological and psychiatric disorders, including OCD and OCPD. In this review, we first address whether hoarding should be considered a symptom of OCD and/or a criterion of OCPD. Second, we address whether compulsive hoarding should be classified as a separate disorder in DSM-V, weighing the advantages and disadvantages of doing so. Finally, we discuss where compulsive hoarding should be classified in DSM-V if included as a separate disorder. We conclude that there is sufficient evidence to recommend the creation of a new disorder, provisionally called hoarding disorder. Given the historical link between hoarding and OCD/OCPD, and the conservative approach adopted by DSM-V, it may make sense to provisionally list it as an obsessive-compulsive spectrum disorder. An alternative to our recommendation would be to include it in an Appendix of Criteria Sets Provided for Further Study. The creation of a new diagnosis in DSM-V would likely increase public awareness, improve identification of cases, and stimulate both research and the development of specific treatments for hoarding disorder.

    Full Text Available La publicación de la quinta edición del DSM ha avivado un debate iniciado tiempo atrás, desde el anuncio de los cambios en los criterios de diagnóstico propuestos por la APA. En este artículo se analizan algunas de estas modificaciones. Se plantean aspectos interesantes y acertados, como la inclusión de la dimensionalidad, tanto en las clases diagnósticas como en algunos trastornos, la incorporación de un espectro obsesivo-compulsivo o la desaparición de los subtipos de esquizofrenia. También se analizan otros aspectos más controvertidos como la consideración del síndrome de psicosis atenuada, la descripción de un trastorno depresivo persistente, la reordenación en trastornos de síntomas somáticos los clásicos trastornos somatoformes, o el mantenimiento de los tres grandes grupos de trastornos de la personalidad, siempre insatisfactorios, junto con un planteamiento anunciado, pero marginal, de la perspectiva dimensional de las alteraciones de la personalidad. La nueva clasificación del DSM-5 abre numerosos interrogantes acerca de la validez que se pretende mejorar en el diagnóstico, en esta ocasión, asumiendo un planteamiento más cercano a la neurología y la genética que a la psicopatología clínica.

    higher than for the adjustment disorder. According to their relevance and their content, we have split the articles into seven subcategories: 1. General description: most scientific articles generally describe the adjustment disorder as being a transition diagnosis, which is ambiguous, marginal and difficult to detect. The findings claim that only a few studies have been conducted on the adjustment disorder despite a high prevalence in the general population and in the clinical field. 2. the DSM-5 defined the adjustment disorder as a set of different outcomes and syndromes induced by stress after a difficult life event. While the link to other disorders has not been mentioned, the diagnosis of this disorder is no longer excluded or perceived as a secondary diagnosis. The DSM-5 faced criticism from three points of view: the operationalization of the concept of stress, the differential diagnosis and the description. 3. Prevalence: different samples have shown a significantly high prevalence of the adjustment disorder within the population. In addition to the psychiatric pain induced by difficult life events we need to emphasize the fact that 12.5 to 19.4 percent of the patients faced heavy and severe pathologies and depended on clinical care and treatment. 4. Etiology, comorbidity or associated symptomatology: the literature identified the tendency to commit suicide and stressful life events as being two fundamental characteristics of adjustment disorder. The third one is the personality profile. 5. that motivates researchers to focus on the adjustment disorder: the differentiation approach as to the major depression. Indeed, the aetiology, the symptomatology and the treatment differ from the adjustment disorder. 6. very recently, Dutch researchers have developed and validated the Diagnostic Interview Adjustment Disorder (DIAD). 7. in 2014, no data or meta-analysis recommended drug treatment in addition to therapy.

    To investigate the reliability, validity and utility of DSM-5 illness anxiety disorder (IAD) and somatic symptom disorder (SSD), and explore their overlap with DSM-IV Hypochondriasis in a health anxious sample. Treatment-seeking patients with health anxiety (N=118) completed structured diagnostic interviews to assess DSM-IV Hypochondriasis, DSM-5 IAD, SSD, and comorbid mental disorders, and completed self-report measures of health anxiety, comorbid symptoms, cognitions and behaviours, and service utilization. IAD and SSD were more reliable diagnoses than Hypochondriasis (kappa estimates: IAD: 0.80, SSD: 0.92, Hypochondriasis: 0.60). 45% of patients were diagnosed with SSD, 47% with IAD, and 8% with comorbid IAD/SSD. Most patients with IAD fluctuated between seeking and avoiding care (61%), whereas care-seeking (25%) and care-avoidant subtypes were less common (14%). Half the sample met criteria for DSM-IV Hypochondriasis; of those, 56% met criteria for SSD criteria, 36% for IAD, and 8% for comorbid IAD/SSD. Compared to IAD, SSD was characterized by more severe health anxiety, somatic symptoms, depression, and higher health service use, and higher rates of major depressive disorder, panic disorder and agoraphobia. DSM-5 IAD and SSD classifications reliably detect more cases of clinically significant health anxiety than DSM-IV Hypochondriasis. The differences between IAD and SSD appear to be due to severity. Future research should explore the generalizability of these findings to other samples, and whether diagnostic status predicts treatment response and long-term outcome. Copyright © 2017 Elsevier Inc.

    2015-04-01

    This study examined the DSM-5 severity criterion for bulimia nervosa (BN) based on the frequency of inappropriate weight compensatory behaviors. 199 community volunteers classified with BN were categorized using DSM-5 severity levels and compared on demographic and clinical variables. 77 (39%) participants were categorized as mild, 68 (34%) as moderate, 32 (16%) as severe, and 22 (11%) as extreme. The severity groups did not differ significantly in demographic variables or body mass index. Shape and Weight concerns did not differ significantly across severity groups. Binge eating differed with the extreme group having significantly higher frequency than the severe, moderate, and mild groups, which did not differ from each other. Restraint differed with the extreme group having significantly higher levels than the mild group. Eating concerns differed with the extreme group having significantly higher levels than moderate and mild groups. Depression differed with the extreme group having significantly higher levels than severe, moderate, and mild groups, which did not differ from each other. Findings from this non-clinical group provide new, albeit modest, support for DSM-5 severity rating for BN based on frequency of inappropriate weight compensatory behaviors. Statistical findings indicate that differences in collateral clinical variables associated with the DSM-5 severity ratings reflect small effect sizes. Further research is needed with treatment-seeking patient groups with BN to establish the validity of the DSM-5 severity specifier and should include broader clinical and functional validators.

    The Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) features two conceptions of Narcissistic Personality Disorder (NPD), one based on the retained DSM-IV's categorical diagnosis and the other based on a model that blends impairments in personality functioning with a specific trait profile intended to recapture DSM-IV NPD. Nevertheless, the broader literature contains a richer array of potential conceptualizations of narcissism, including distinguishable perspectives from psychiatric nosology, clinical observation and theory, and social/personality psychology. This raises questions about the most advantageous pattern of traits to use to reflect various conceptions of narcissistic pathology via the Personality Inventory for the DSM-5 (PID-5). In this study, we examine the associations of the Personality Disorder Questionnaire-Narcissistic Personality Disorder scale, Narcissistic Personality Inventory-16, and the Pathological Narcissism Inventory and the PID-5 dimensions and facets in a large sample (N = 1,653) of undergraduate student participants. Results point to strong associations with PID-5 Antagonism scales across narcissism measures, consistent with the DSM-5's proposed representation of NPD. However, additional notable associations emerged with PID-5 Negative Affectivity and Psychoticism scales when considering more clinically relevant narcissism measures.

    This paper evaluates the proposal for antisocial personality disorder (ASPD) in the Diagnostic and Statistical Manual of Mental Disorders-fifth edition (DSM-5). Some aspects of the proposal are appealing: personality disorders will be assessed using trait criteria, and these criteria are similar to trait descriptions of DSM-IV ASPD. Other aspects of the proposal are less appealing. First, the DSM-5 will depend on a newly constructed personality trait system rather than relying on a well validated, widely studied one. Second, the trait profile of ASPD is incomplete; although this profile reflects the traits included in DSM-IV, it maps poorly onto the full personality profile of ASPD. Third, the DSM Workgroup missed an opportunity to finally unify ASPD and psychopathy; history and research suggest that these disorders have diverged mistakenly. Fourth, the newly proposed criteria of impairments in self- and interpersonal functioning are of questionable derivation and utility. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

    OBJECTIVE: The personality disorder domains proposed for the ICD-11 comprise Negative Affectivity, Detachment, Dissociality, Disinhibition, and Anankastia, which are reasonably concordant with the higher-order trait domains in the Alternative DSM-5 Model for Personality Disorders. METHOD: We...... replication sample (N = 637) completed the Personality Inventory for DSM-5 (PID-5). Sixteen PID-5 traits were designated to cover features of the ICD-11 trait domains. RESULTS: Exploratory structural equation modeling (ESEM) analyzes showed that the designated traits were meaningfully organized......-11 personality disorder domains can be accurately described using designated traits from the DSM-5 personality trait system. A scoring algorithm for the ICD-11 personality disorder domains is provided in appendix....

    The present review was conducted in order to evaluate the current diagnostic criteria for specific phobia (SP) in light of the empirical evidence gathered since DSM-IV and to propose changes to DSM-V where change is clearly and reliably indicated by the evidence. In response to questions put forth by the DSM-V Anxiety, OC Spectrum, Posttraumatic, and Dissociative Disorder Work Group, four primary areas were determined for this review: the accuracy and utility of the current SP type classification system, the validity of test anxiety as a type of SP, the boundary between agoraphobia and SP, and the reliability and utility of the diagnostic criteria for SP. Developmental issues are addressed within each area. Literature reviews examining academic findings published between 1994 and 2009 were carried out and the results are included herein. The review presents a number of options and preliminary recommendations to be considered for DSM-V. All of these recommendations should be considered tentative as they await the field trials and expert consensus necessary prior to their inclusion in the DSM-V. The present review also reveals a great need for future research in the area of SP and directions for such research is provided.

  6. Narcissistic pathology as core personality dysfunction: comparing the DSM-IV and the DSM-5 proposal for narcissistic personality disorder.

    Narcissistic personality disorder and related concepts have a complex history and have been subject to extensive theoretical discourse but relatively little empirical research. An initial proposal for the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) that suggested eliminating this disorder as a discrete personality disorder type met with considerable controversy that ultimately led to its reinstatement in subsequent proposals. Nonetheless, the DSM-5 proposal for personality disorders as a whole would involve a significantly different formulation of narcissistic personality from that described in DSM-IV-one that places a greater emphasis on shared deficits among all personality disorders that tap elements thought to fall on the narcissistic spectrum, such as deficits in empathic capacity. This article describes this revised formulation, and presents a case study that illustrates the similarities and differences in the DSM-IV and proposed DSM-5 portrayal of narcissistic issues and related clinical problems over the course of a particular treatment. © 2012 Wiley Periodicals, Inc.

    ABSTRACTStudies indicate that DSM-5 criteria for delirium are relatively restrictive, and identify different cases of delirium compared with previous systems. We evaluate four outcomes of delirium (mortality, length of hospital stay, institutionalization, and cognitive improvement) in relation to delirium defined by different DSM classification systems.Prospective, longitudinal study of patients aged 70+ admitted to medical wards of a general hospital. Participants were assessed up to a maximum of four times during two weeks, using DSM-5 and DSM-IV criteria, DRS-R98 and CAM scales as proxies for DSM III-R and DSM III.Of the 200 assessed patients (mean age 81.1, SD = 6.5; and 50% female) during hospitalization, delirium was identified in 41 (20.5%) using DSM-5, 45 (22.5%) according to DSM-IV, 46 (23%) with CAM positive, and 37 (18.5%) with DRS-R98 severity score >15. Mortality was significantly associated with delirium according to any classification system, but those identified with DSM-5 were at greater risk. Length of stay was significantly longer for those with DSM-IV delirium. Discharge to a care home was associated only with DRS-R98 defined delirium. Cognitive improvement was only associated with CAM and DSM-IV. Different classification systems for delirium identify populations with different outcomes.

  8. [An approach to DSM-5: a breakthrough in psychiatry?].

    One of the main problems of current psychiatry is that its diagnostic classification systems are not precise and reliable, they do not help to identify with certainty a specific type of mental disorder and they frequently overlap two or more diagnoses. This may conduce to over diagnosis and overtreatment, which is the main criticism of the DSM system. The American Psychiatric Association (APA) launched recently the DSM-5, the fifth edition of its diagnostic manual, which provides diagnostic criteria for thousands of psychiatrist, psychologist and researchers and who will be using it in the next coming years. DSM-5, like the preceding editions, placed disorders in discrete categories such as bipolar disorder or schizophrenia. The problem is that scientists have been unable to find yet a genetic or neurobiological evidence to support the theory of mental disorders as separate categories. Several authors wanted the latest DSM to move away from the category model towards a new "dimensional approach", where disorders can be measured and mental illnesses overlapping can be reduced. Recent findings supports this new dimensional strategy, suggesting that the disorders are a product of shared risk factors that lead to abnormalities in specific drives, which can be measured and used to place persons on one of several spectra. In some parts the DSM-5 entered changes aiming to achieve a greater objectivity. The door for new changes in each category, dimension or criteria has been opened, favoring an evidence-based development of the future versions. DSM-5 is presented as a "living document" that can be updated easily. However, the category model still remains for many disorders. The future research in psychiatric diagnostic systems requires more genetic-molecular and neurophysiological evidence and more objective multinational field trials, in order to confirm the existence of the new diagnostic entities, spectrums or dimensions. This approach may provide us reliable

    The anxiety disorders specified in the fourth edition, text revision, of The Diagnostic and Statistical Manual (DSM-IV-TR) are identified universally in human societies, and also show substantial cultural particularities in prevalence and symptomatology. Possible explanations for the observed epidemiological variability include lack of measurement equivalence, true differences in prevalence, and limited validity or precision of diagnostic criteria. One central question is whether, through inadvertent "over-specification" of disorders, the post-DSM-III nosology has missed related but somewhat different presentations of the same disorder because they do not exactly fit specified criteria sets. This review canvases the mental health literature for evidence of cross-cultural limitations in DSM-IV-TR anxiety disorder criteria. Searches were conducted of the mental health literature, particularly since 1994, regarding cultural or race/ethnicity-related factors that might limit the universal applicability of the diagnostic criteria for six anxiety disorders. Possible mismatches between the DSM criteria and the local phenomenology of the disorder in specific cultural contexts were found for three anxiety disorders in particular. These involve the unexpectedness and 10-minute crescendo criteria in Panic Disorder; the definition of social anxiety and social reference group in Social Anxiety Disorder; and the priority given to psychological symptoms of worry in Generalized Anxiety Disorder. Limited evidence was found throughout, particularly in terms of neurobiological markers, genetic risk factors, treatment response, and other DSM-V validators that could help clarify the cross-cultural applicability of criteria. On the basis of the available data, options and preliminary recommendations for DSM-V are put forth that should be further evaluated and tested.

    The aim of this study was to test the operationalization of DSM-5 somatic symptom disorder (SSD) psychological criteria among Chinese general hospital outpatients. This multicenter, cross-sectional study enrolled 491 patients from 10 general hospital outpatient departments. The structured clinical "interview about cognitive, affective, and behavioral features associated with somatic complaints" was used to operationalize the SSD criteria B. For comparison, DSM-IV somatoform disorders were assessed with the Mini International Neuropsychiatric Interview plus. Cohen's к scores were given to illustrate the agreement of the diagnoses. A three-structure model of the interview, within which items were classified as respectively assessing the cognitive (B1), affective (B2), and behavioral (B3) features, was examined. According to percentages of screening-positive persons and the receiver operator characteristic (ROC) analysis, a cut-off point of 2 was recommended for each subscale of the interview. With the operationalization, the frequency of DSM-5 SSD was estimated as 36.5% in our sample, and that of DSM-IV somatoform disorders was 8.2%. The agreement between them was small (Cohen's к = 0.152). Comparisons of sociodemographic features of SSD patients with different severity levels (mild, moderate, severe) showed that mild SSD patients were better-off in terms of financial and employment status, and that the severity subtypes were congruent with the level of depression, anxiety, quality of life impairment, and the frequency of doctor visits. The operationalization of the diagnosis and severity specifications of SSD was valid, but the diagnostic agreement between DSM-5 SSD and DSM-IV somatoform disorders was small. The interpretation the SSD criteria should be made cautiously, so that the diagnosis would not became over-inclusive.

  11. A new strategy for DSM and Market Transformation

    Demand Side Management (DSM) as a utility instrument has been based on the assumption that supply in itself is well run and managed and that corrections should only be made by adjusting demand to a more appropriate level. The entire energy system, however, needs tuning from both the supply side and the demand side. DSM has to be reshaped to fit both the utilities, in a competitive environment, and more general societal purposes. Market Transformation aims at moving the benchmark for performance of products; focusing customer and supplier interest on high performance, thus getting larger volumes for such equipment; and clearing the market of inferior products.

    DSmT (Dezert-Smarandache Theory) is a new alternative to Dempster-Shafer Theory (DST) which: 1) proposes a new mathematical framework for information fusion; 2) incorporates any kind of model (free, hybrid DSm models, and/or Shafer's model) for taking into account any integrity constraints of the fusion problem; 3) combines uncertain, high conflicting, and imprecise sources of evidence with a new rule of combination and overcomes limitations of the Dempster's rule; 4) is adapted to static or dynamic fusion applications represented in terms of belief functions based on the same general formalism.

    This paper presents a method of reshaping and extraction of markers and masks of the dense houses from the DSM based on mathematical morphology (MM). Houses in a digital surface model (DSM) are almost joined together in high-density housing areas, and most segmentation methods cannot completely separate them. We propose to label the markers of the buildings firstly and segment them into masks by watershed then. To avoid detecting more than one marker for a house or no marker at all d...

    The purpose of this study was to document the functional severity of DSM-5 IED in a clinical research sample. IED and control groups were compared on psychosocial functioning, life satisfaction, and on a variety of cognitive and behavioral issues. IED study participants reported significantly worse psychosocial function, quality of life, and higher job dysfunction than both psychiatric and healthy control study participants. The presence of DSM-5 IED is associated with significant psychosocial and functional impairment. Early intervention may aid in minimizing the consequences of impulsive aggressive behavior, and improving psychosocial functioning and quality of life. Copyright © 2018 Elsevier B.V.

    Background: Recently, changes have been introduced to the diagnostic criteria for posttraumatic stress disorder (PTSD) according to the Diagnostic and Statistical Manual of Mental Disorders (DSM) and the International Classification of Diseases (ICD). Objectives: This study investigated the effect of the diagnostic changes made from DSM-IV to DSM-5 and from ICD-10 to the proposed ICD-11. The concordance of provisional PTSD prevalence between the diagnostic criteria was examined in a convenience sample of 100 members of the German Armed Forces. Method: Based on questionnaire measurements, provisional PTSD prevalence was assessed according to DSM-IV, DSM-5, ICD-10, and proposed ICD-11 criteria. Consistency of the diagnostic status across the diagnostic systems was statistically evaluated. Results: Provisional PTSD prevalence was the same for DSM-IV and DSM-5 (both 56%) and comparable under DSM-5 versus ICD-11 proposal (48%). Agreement between DSM-IV and DSM-5, and between DSM-5 and the proposed ICD-11, was high (both p  DSM-IV, DSM-5, and proposed ICD-11. This supports the assumption of a set of PTSD core symptoms as suggested in the ICD-11 proposal, when at the same time a satisfactory concordance between ICD-11 proposal and DSM was given. The finding of increased provisional PTSD prevalence under ICD-11 proposal in contrast to ICD-10 can be of guidance for future epidemiological research on PTSD prevalence, especially concerning further investigations on the impact, appropriateness, and usefulness of the time criterion included in ICD-10 versus the consequences of its deletion as proposed for ICD-11.

    International Nuclear Information System (INIS)

    Dayton, D.S.

    1992-01-01

    Opportunities to make investments in demand side management (DSM) are widespread, especially among large, complex, energy-intensive customers. Acceptable economics are found for energy efficiency improvements, new construction or renovation, replacement of failing or obsolete equipment, and retrofit of existing facilities with more efficient equipment and operations. Market imperfections and technical limitations intrude on the DSM investment process. These intrusions are examined from a financial viewpoint by considering the return on investment and risks faced by the three potential investors in DSM opportunities: the customer, the utility, and the third party contractor or financier. These risks are illustrated by examining the cash flow of a typical project depicting a comprehensive energy efficiency installation in a medium to large industrial or institutional facility. The spread between the customer's risk/return ratio and that of the other two investors is shown to be surprisingly large. A utility role in marketing and financing, as opposed to direct subsidizing of customers or direct purchase of DSM resources from third parties, is explored as an efficient response to these realities. 2 figs., 3 tabs

    The Diagnostic and Statistical Manual of Mental Disorders (DSM) is published by the American Psychiatric Association (APA) as a guide for diagnosing psychiatric diseases and enables the alignment of psychiatric diagnoses with those of the psychologists, the social workers, the nursing staff and other mental health professionals. In addition, it helps bring cohesion to research, public health policy, education, the field of insurance and compensation and the legal system. After 14 years of hard work, the updated version of the DSM, the DSM-5, was published on May 2013. The current review aims to update the readers on the essence of the DSM and the methods of psychiatric diagnosing and to present the main changes in the field, as expressed in the 5th edition of the guide. In addition to details of those changes we included discussions of the criticisms brought against them. We hope that the review will contribute to broadening the readers' knowledge, broaden exposure and familiarity with the psychiatric lingo and to strengthening the professional ties between psychiatrists and professionals in other, tangential, medical fields.
