    In 1981, Glenn Research Center scientist Dr. Larry Viterna developed a model that predicted certain elements of wind turbine performance with far greater accuracy than previous methods. The model was met with derision from others in the wind energy industry, but years later, Viterna discovered it had become the most widely used method of its kind, enabling significant wind energy technologies-like the fixed pitch turbines produced by manufacturers like Aerostar Inc. of Westport, Massachusetts-that are providing sustainable, climate friendly energy sources today.

  3. Opportunities in Canada's growing wind energy industry

    2006-01-01

    Investment in Canada's wind sector is projected to reach $8 billion by 2012, and growth of the sector is expected to create over 16,000 jobs. Canada's wind energy capacity grew by 54 per cent in 2005 alone, aided in part by supportive national policies and programs such as the Wind Power Production Incentive (WPPI); the Canadian Renewable Conservation Expense (CRCE) and Class 43.1 Capital Cost Allowance; and support for research and development. Major long-term commitments for clean power purchases, standard offer contracts and renewable portfolio standards in several provinces are encouraging further development of the wind energy sector. This paper argued that the development of a robust Canadian wind turbine manufacturing industry will enhance economic development, create opportunities for export; and mitigate the effects of international wind turbine supply shortages. However, it is not known whether Canadian wind turbine firms are positioned to capitalize on the sector's recent growth. While Canada imports nearly all its large wind turbine generators and components, the country has technology and manufacturing strengths in advanced power electronics and small wind systems, as well as in wind resource mapping. Wind-diesel and wind-hydrogen systems are being developed in Canada, and many of the hybrid systems will offer significant opportunities for remote communities and off-grid applications. Company partnerships for technology transfer, licensing and joint ventures will accelerate Canada's progress. A recent survey conducted by Industry Canada and the Canadian Wind Energy Association (CanWEA) indicated that the total impact of wind energy related expenditures on economic output is nearly $1.38 billion for the entire sector. Annual payroll for jobs in Canada was estimated at $50 million, and substantial employment growth in the next 5 years is expected. Canada offers a strong industrial supply base capable of manufacturing wind turbine generators and

    2012-12-01

    In 2010, wind energy coverage in Spain increased by 16%, making the country the world's fourth largest producer in a fast-developing industry that is also a source of employment. Occupational skin diseases in this field have received little attention. The present study aims to describe the main characteristics of skin diseases affecting workers in the wind energy industry and the allergens involved. We performed a descriptive, observational study of workers from the wind energy industry with suspected contact dermatitis who were referred to the occupational dermatology clinic of the National School of Occupational Medicine (Escuela Nacional de Medicina del Trabajo) between 2009 and 2011. We took both a clinical history and an occupational history, and patients underwent a physical examination and patch testing with the materials used in their work. We studied 10 workers (8 men, 2 women), with a mean age of 33.7 years. The main finding was dermatitis, which affected the face, eyelids, forearms, and hands. Sensitization to epoxy resins was detected in 4 workers, 1 of whom was also sensitized to epoxy curing agents. One worker was sensitized to bisphenol F resin but had a negative result with epoxy resin from the standard series. In the 5 remaining cases, the final diagnosis was irritant contact dermatitis due to fiberglass. Occupational skin diseases are increasingly common in the wind energy industry. The main allergens are epoxy resins. Fiberglass tends to produce irritation. Copyright © 2012 Elsevier España, S.L. and AEDV. All rights reserved.

  8. Feasibility of industrial wind energy schemes - final report

    1998-01-01

    This document is the final report of an investigation into the feasibility of using wind turbines as on-site generation (i.e. on the customer''s side of the meter) to meet a proportion of the electricity demand on industrial sites in the UK. It was thought that this could become a promising market for wind energy outside support mechanisms such as the Non Fossil Fuel Obligation and equivalents, for the following principal reasons: electricity which displaces purchases from a Public Electricity Supplier (PES) or Second Tier Support (STS) has a higher value than electricity sold direct to a PES or STS; there could be seasonal and diurnal correlation between the output of wind turbines and electricity prices; and due to existing infrastructure, realisation of such projects could be simpler and cheaper than for new wind farms. Six industrial sites participated in the project, covering a wide range of industries, locations, and wind regimes. For each site, a year of concurrent wind data and demand data was produced. Practical aspects of the implementation of such schemes, and the results of the time step analyses, were discussed with the participating sites and the host PESs for each site. (author)

    As a consequence of the growing wind energy market in Germany the importance of the industry in this business are has grown. In 1994 the turnover will go beyond 500 million DM, and the number of employees will reach 2,900. The turnover and the number of employees are increasing in spite of the higher efficiency. In 1994 only 5 employees are needed by a manufacturer to install 1 MW rated power instead of 15 in 1989, and the ratio of installed power to manufacturer's turnover has risen from 0,25 W/DM in 1988 to 0,455 W/DM in 1994. On the other hand the turnover of the manufacturers per employee has increased from 80,000 DM in 1988 to 440,000 DM in 1994. Economic development has considerably been advanced by subsidies for the application of wind energy technology. (orig.)

    2010-01-01

    Risk-based analysis techniques are used to quantify and prioritize a wide variety of problems within the traditional fossil fuel and nuclear power industries. This poster presentation evaluated some of the risk analysis tools and methods used by the energy industry to quantify and manage wind energy development risks. A comprehensive risk-based approach for identifying the probability and consequences of potential concerns was presented for a sample wind energy project. The process determined objectives in relation to the project's net present value. Contributing domains included the energy production, prices, and operating costs of the project. Decision criteria used to evaluate the desirability of the wind project were then developed. Monte Carlo simulations were the used to aggregate individual risks into an overall total. The contribution of each element to the decision objective was calculated separately. The element outputs were than combined into a measure of aggregate risk exposure. Aggregate results were used to calculate the decision criteria. The decision objective was to determine if the energy cost was less than the avoided cost of other project options. The study showed that the approach can allow decision-makers to mitigate risks. However, the results are dependent on the quality of the input data. tabs., figs.

    Results of the fast growing wind energy market in 1994 are the turnover reaching more than 800 million DM, and the number of employees to about 3,700. In 1995 the manufacturers expect to need less than 4 employees to build and to install 1 MW rated power and to decrease the ratio of manufacturer's turnover per installed power unit to about 1900 DM/kW. In spite of this development it is expected that the turnover and the number of employees will increase due to the still fast growing market. (orig.)

  16. Fostering a Renewable Energy Technology Industry: An InternationalComparison of Wind Industry Policy Support Mechanisms

    Lewis, Joanna; Wiser, Ryan

    2005-11-15

    This article examines the importance of national and sub-national policies in supporting the development of successful global wind turbine manufacturing companies. We explore the motivations behind establishing a local wind power industry, and the paths that different countries have taken to develop indigenous large wind turbine manufacturing industries within their borders. This is done through a cross-country comparison of the policy support mechanisms that have been employed to directly and indirectly promote wind technology manufacturing in twelve countries. We find that in many instances there is a clear relationship between a manufacturer's success in its home country market and its eventual success in the global wind power market. Whether new wind turbine manufacturing entrants are able to succeed will likely depend in part on the utilization of their turbines in their own domestic market, which in turn will be influenced by the annual size and stability of that market. Consequently, policies that support a sizable, stable market for wind power, in conjunction with policies that specifically provide incentives for wind power technology to be manufactured locally, are most likely to result in the establishment of an internationally competitive wind industry.

    WWF (the World Wide Fund for Nature) is convinced that Climate Change is one of the major long term threats to global biodiversity. At an international level WWF seeks to highlight the actual and predicted effects of Climate Change upon the natural environment, human health, and national economies in order to press governments and industry to set and achieve an ambitious target for the reduction of greenhouse gas emissions - 20% by 2005. At the national level, we are working with other NGOs, and industry to promote solutions. WWF is pressing for a reform of government measures to stimulate the renewable energy industry and developing its own 'green electricity' initiative in anticipation of deregulation of the electricity market in 1998. It is hoped that this scheme will both provide a market opportunity to a range of technologies and developers, and give a clear demonstration that there is a strong demand among British consumers for renewable energy. WWF wishes to work with all players, starting perhaps with BWEA and WWF working together on the recently announced DTI 'review of its strategy for the development of renewables technology'. (Author)

    In order to reduce its greenhouse gas emissions and combat global warming, France has set itself the objective, within the framework of a European directive, of sourcing 21% of its electricity needs from renewable energies by 2010. Among the various renewable energies, wind energy has a significant part to play, since France has the second highest wind resource potential in Europe, after the UK. Denis Florin and Florian Temime offer an account here of the wind energy industry and the various players within it. After a brief analysis of the world market for wind power, characterized by rising demand and by a supply that is currently in a phase of consolidation, they examine three groups of players in this sector - industrialists tempted by vertical integration, electricity producers and oil companies - and set out their respective strategies and future outlooks with regard to wind energy.

    The wind industry and the U.S. Department of Energy (DOE) are addressing technical challenges to increasing wind energy's contribution to the national grid (such as reducing turbine costs and increasing energy production and reliability), and they recognize that public acceptance issues can be challenges for wind energy deployment. Wind project development decisions are best made using unbiased information about the benefits and impacts of wind energy. In 2014, DOE established six wind Regional Resource Centers (RRCs) to provide information about wind energy, focusing on regional qualities. This document summarizes the status and drivers for U.S. wind energy development on regional and state levels. It is intended to be a companion to DOE's 2014 Distributed Wind Market Report, 2014 Wind Technologies Market Report, and 2014 Offshore Wind Market and Economic Analysis that provide assessments of the national wind markets for each of these technologies.

    Wind energy decision makers are required to make critical judgments on a daily basis with regard to energy generation, distribution, demand, storage, and integration. Accurate knowledge of the present and future state of the atmosphere is vital in making these decisions. As wind energy portfolios expand, this forecast problem is taking on new urgency because wind forecast inaccuracies frequently lead to substantial economic losses and constrain the national expansion of renewable energy. Improved weather prediction and precise spatial analysis of small-scale weather events are crucial for renewable energy management. In early 2009, the National Center for Atmospheric Research (NCAR) began a collaborative project with Xcel Energy Services, Inc. to perform research and develop technologies to improve Xcel Energy's ability to increase the amount of wind energy in their generation portfolio. The agreement and scope of work was designed to provide highly detailed, localized wind energy forecasts to enable Xcel Energy to more efficiently integrate electricity generated from wind into the power grid. The wind prediction technologies are designed to help Xcel Energy operators make critical decisions about powering down traditional coal and natural gas-powered plants when sufficient wind energy is predicted. The wind prediction technologies have been designed to cover Xcel Energy wind resources spanning a region from Wisconsin to New Mexico. The goal of the project is not only to improve Xcel Energy’s wind energy prediction capabilities, but also to make technological advancements in wind and wind energy prediction, expand our knowledge of boundary layer meteorology, and share the results across the renewable energy industry. To generate wind energy forecasts, NCAR is incorporating observations of current atmospheric conditions from a variety of sources including satellites, aircraft, weather radars, ground-based weather stations, wind profilers, and even wind sensors on

    This paper aims to evaluate the potential of renewable energy sources of solar and wind in three free economic and industrial zones of Chabahar, Kish and Salafchegan in Iran. Feasibility of harnessing solar energy was investigated by using key solar parameters like monthly mean global, beam and diffuse solar radiation as well as clearness index. It was found that all locations had great potentials for utilizing different solar energy systems. Additionally, the monthly, seasonal, semi-yearly and yearly optimum tilt angles of south-facing solar surfaces were determined. For all zones, adjusting the tilt angle twice a year or in other words, the semi-yearly tilt adjustment for two periods of warm (April–September) and cold (October–March) were highly recommended, since it offers almost the same level of annual solar energy gain (SEG) as those of monthly and seasonal adjustments. Weibull Distribution Function (WDF) was performed for analyzing the wind potentials at different heights. It was found that Chabahar was not suitable for wind energy development, but Kish and Salafchegan with yearly wind powers of 111.28 W/m 2 and 114.34 W/m 2 , respectively ranked in class 2 which are considered marginal for wind power development. Three different wind turbine models were proposed for Kish and Salafchegan. - Highlights: • Feasibility of solar and wind energy for three locations of Iran was investigated. • All locations were suitable for solar energy utilization. • The optimum tilt angles of solar surfaces were determined. • Chabahar was unsuitable, but Kish and Salafchegan were marginal for wind purpose

    Industrial initiatives are methods of lobbying and marketing to increase the activity, revenues, profits, and commercial viability of an industry. They may be undertaken by industry individuals or firms, industry groups, government agencies, or combinations of all these. In Canada, one example of an industrial initiative is the Canadian Wind Energy Association. Other initiatives relevant to the wind power industry include Technology Inflow Programs sponsored by External Affairs Canada, used for visiting foreign firms with the view to licensing foreign technology, and Industrial Research Assistance Programs to develop or adapt new technologies in partnership with government. The Conservation/Renewable Energy Council, Small Power Producers of Alberta, and Independent Power Producers Society of Ontario are also active in supporting wind energy initiatives. In other countries, notable initiatives for wind energy include the Danish wind turbine warranty guarantee program. The Western Wind Industry Network of Canada conducts regional lobbying. It is suggested that in Canada, more such networks are needed, as well as joint ventures with utilities and governments, and more work with the regulatory agencies, to promote wind energy

    Wind energy should be an important part of the energy supply mix, both at home and abroad, to provide cleaner air and a more stable fuel supply. Not only can wind energy contribute to solving complex global issues, it also can provide a large market for American technological leadership. Even though utilities are paying more attention to wind in a number of states, there are no plans for major installations of wind power plants in the United States. At the same time, European nations have developed aggressive wind energy development programs, including both ambitious research and development efforts and market incentives. Many countries recognize the importance of the clean energy provided by wind technology and are taking steps to promote their fledgling domestic industries. The emphasis on market incentives is starting to pay off. In 1991, European utilities and developers installed nearly twice as much wind capacity as Americans did. In 1992 the gap will be even greater. This article reviews aggressive incentives offered by European governments to boost their domestic wind industries at home and abroad in this almost $1 billion per year market. By offering substantial incentives - considerably more than the American Wind Energy Association (AWEA) is proposing - European nations are ensuring dramatic near-term wind energy development and are taking a major step toward dominating the international wind industry of the 21st century

    The wind power industry is a dynamic sector that continues to grow, year after year. In 2014 there was a significant increase in wind power both in France and the rest of the world, with installed capacity rising to over 1,000 MW and 51,000 MW respectively. These figures demonstrate the economic importance of the sector, which now sees 75 billion euros invested annually worldwide. France's wind energy industry has everything it needs to become a world-leader in the sector, thanks to its skill and expertise in the fields of mechanics, electrical engineering and civil engineering. To help our businesses grasp the opportunities offered by the wind power market, the Windustry France 2.0 programme aims to strengthen the French subcontracting base, which primarily comprises specialised SMEs and middle-market companies that export their products. So far the programme's steering committee has identified fifty companies, over forty of which have already benefited from the specialist knowledge and expertise, specific to their particular core business, that can help them move into the wind energy industry. For ten of them, the Windustry France 2.0 initiative has already resulted in effective diversification into these sectors, and the opening up of new markets. The recent decision to extend the Windustry France 2.0 industrial structuring programme until October 2016 means that an extra 20 companies will now benefit from the programme, taking the total to 70. It also bears witness to the government's intention to make the sector one of the pillars of New Industrial France. More and more companies are realising that the wind energy sector represents a pathway for strategic growth - our aim is to enable them to enter the sector as quickly and effectively as possible. In the longer term, we will also need to start looking at wind farm maintenance and operation - here too it is vitally important for us to develop a competent French industry in the sector

    The wind energy or eolic energy is a consequence of solar energy, the one which is absorbed by the atmosphere and is transformed into energy of movement of large bulks of air. In this process the atmosphere acts as the filter to the solar radiation and demotes the ultraviolet beams that result fatal to life in the Earth. The ionosphere is the most external cap and this is ionized by means of absorption process of ultraviolet radiation arising to the Sun. The atmosphere also acts as a trap to the infrared radiation, it that results from the continual process of energetic degradation. In this way, the interaction between Earth - Atmospheres, is behaved as a great greenhouse, maintaining the constant temperatures, including in the dark nights. Processes as the natural convection (that occur by the thermodynamic phenomenon), equatorial calmness, trade winds and against trade winds and global distribution of the air currents are described. The other hand, techniques as the transformation of the wind into energy and its parameters also are shown

    When wildlife habitat overlaps with industrial development animals may be harmed. Because wildlife and people select resources to maximize biological fitness and economic return, respectively, we estimated risk, the probability of eagles encountering and being affected by turbines, by overlaying models of resource selection for each entity. This conceptual framework can be applied across multiple spatial scales to understand and mitigate impacts of industry on wildlife. We estimated risk to Golden Eagles (Aquila chrysaetos) from wind energy development in 3 topographically distinct regions of the central Appalachian Mountains of Pennsylvania (United States) based on models of resource selection of wind facilities (n = 43) and of northbound migrating eagles (n = 30). Risk to eagles from wind energy was greatest in the Ridge and Valley region; all 24 eagles that passed through that region used the highest risk landscapes at least once during low altitude flight. In contrast, only half of the birds that entered the Allegheny Plateau region used highest risk landscapes and none did in the Allegheny Mountains. Likewise, in the Allegheny Mountains, the majority of wind turbines (56%) were situated in poor eagle habitat; thus, risk to eagles is lower there than in the Ridge and Valley, where only 1% of turbines are in poor eagle habitat. Risk within individual facilities was extremely variable; on average, facilities had 11% (SD 23; range = 0-100%) of turbines in highest risk landscapes and 26% (SD 30; range = 0-85%) of turbines in the lowest risk landscapes. Our results provide a mechanism for relocating high-risk turbines, and they show the feasibility of this novel and highly adaptable framework for managing risk of harm to wildlife from industrial development. © 2014 Society for Conservation Biology.

    1998-01-01

    The current status of wind technology developments in Canada and around the world was reviewed. Information regarding the level of wind turbine deployment was presented. It was shown that significant effort has been made on the national and international level to increase the capacity of this clean, non-polluting form of energy. Wind energy has become competitive with conventional sources of electricity due to lower cost, higher efficiency and improved reliability of generating equipment. The advantages and disadvantages of wind electricity generating systems and the economics and atmospheric emissions of the systems were described. At present, there is about 23 MW of wind energy generating capacity installed in Canada, but the potential is very large. It was suggested that wind energy could supply as much as 60 per cent of Canada's electricity needs if only one per cent of the land with 'good winds' were covered by wind turbines. Recently, the Canadian government has provided an accelerated capital cost allowance for certain types of renewable energies under the Income Tax Act, and the flow-through share financing legislation to include intangible expenses in certain renewable energy projects has been extended. Besides the support provided to the private sector through tax advantages, the Government also supports renewable energy development by purchasing 'green' energy for its own buildings across the country, and by funding a research and development program to identify and promote application of wind energy technologies, improve its cost effectiveness, and support Canadian wind energy industries with technology development to enhance their competitiveness at home and abroad. Details of the Wind Energy Program, operated by Natural Resources Canada, are described. 3 tabs., 5 figs

    Wind energy is perhaps the most advanced of the 'new' renewable energy technologies, but there is still much work to be done. This roadmap identifies the key tasks that must be undertaken in order to achieve a vision of over 2 000 GW of wind energy capacity by 2050. Governments, industry, research institutions and the wider energy sector will need to work together to achieve this goal. Best technology and policy practice must be identified and exchanged with emerging economy partners, to enable the most cost-effective and beneficial development.

    Employment opportunities in the United Kingdom wind power industry are reviewed and compared to job availability in Europe, Canada and the USA, using a postal questionnaire. Most jobs were in manufacturing with consultancy and contract research forming another large group; with over two-thirds being in medium to microsized organizations, a size distribution similar to the manufacturing sector of the United Kingdom economy. Professional and management occupations account for over half of the total jobs making the wind industry a highly skilled area. Estimates suggest that, taking account of direct jobs, and those indirectly associated with the wind power industry, only about 2200 full-time equivalent jobs currently exist in the United Kingdom.

    Wind energy is diffuse but was widely used before the industrial revolution. The first oil crisis triggered renewed interest in wind energy technology in remote areas. Winds develop when solar radiation reaches the earth's highly varied surface unevenly, creating temperature density and pressure differences. The earth's atmosphere has to circulate to transport heat from the tropics towards the poles. On a global scale, these atmospheric currents work as an immense energy transfer medium. Three main applications can be distinguished: wind pumps, off-grid applications and grid-connected applications. The total generating costs for wind turbine systems are determined by total investments costs, the life time, the operating and maintenance costs, the wind regime (the wind energy potential is proportional to v 3 where v is the wind speed), the efficiency and availability of the wind turbine. The main gains are achieved as a result of improved reliability. The optimum size of a wind turbine depends on the wind speed, the wind turbine costs, the construction costs, the environmental impact and the social costs. The value of wind energy depends on the application that is made of the energy generated and on the costs of alternatives, it can be calculated by the avoided costs of damage to flora, fauna and mankind due to acid rain deposition, enhancement of the greenhouse effect. The environmental aspects are bird hindrance, noise, telecommunication interference and safety. 2 tabs., 1 fig

    The generation of electricity in the United States from wind-powered turbines is increasing. An understanding of the sources and abundance of raw materials required by the wind turbine industry and the many uses for these materials is necessary to assess the effect of this industry's growth on future demand for selected raw materials relative to the historical demand for these materials. The U.S. Geological Survey developed estimates of future requirements for raw (and some recycled) materials based on the assumption that wind energy will supply 20 percent of the electricity consumed in the United States by 2030. Economic, environmental, political, and technological considerations and trends reported for 2009 were used as a baseline. Estimates for the quantity of materials in typical "current generation" and "next generation" wind turbines were developed. In addition, estimates for the annual and total material requirements were developed based on the growth necessary for wind energy when converted in a wind powerplant to generate 20 percent of the U.S. supply of electricity by 2030. The results of the study suggest that achieving the market goal of 20 percent by 2030 would require an average annual consumption of about 6.8 million metric tons of concrete, 1.5 million metric tons of steel, 310,000 metric tons of cast iron, 40,000 metric tons of copper, and 380 metric tons of the rare-earth element neodymium. With the exception of neodymium, these material requirements represent less than 3 percent of the U.S. apparent consumption for 2008. Recycled material could supply about 3 percent of the total steel required for wind turbine production from 2010 through 2030, 4 percent of the aluminum required, and 3 percent of the copper required. The data suggest that, with the possible exception of rare-earth elements, there should not be a shortage of the principal materials required for electricity generation from wind energy. There may, however, be selective

    Wind energy is rapidly growing. In 2006 the installed generating capacity in the world increased by 25%, a growth rate which has more or less been sustained during the last decade. And there is no reason to believe that this growth will slow significantly in the coming years. For example, the United Kingdom's goal for installed wind turbines by 2020 is 33 GW up from 2 GW in 2006, an average annual growth rate of 22% over that period. More than half of all turbines are installed in Europe, but United States, India and lately China are also rapidly growing markets. The cradle of modern wind energy was set by innovative blacksmiths in rural Denmark. Now the wind provides more than 20% of the electrical power in Denmark, the industry has professionalized and has close ties with public research at universities. This focus issue is concerned with research in wind energy. The main purposes of research in wind energy are to: decrease the cost of power generated by the wind; increase the reliability and predictability of the energy source; investigate and reduce the adverse environmental impact of massive deployment of wind turbines; build research based educations for wind energy engineers. This focus issue contains contributions from several fields of research. Decreased costs cover a very wide range of activities from aerodynamics of the wind turbine blades, optimal site selection for the turbines, optimization of the electrical grid and power market for a fluctuating source, more efficient electrical generators and gears, and new materials and production techniques for turbine manufacturing. The United Kingdom recently started the construction of the London Array, a 1 GW off-shore wind farm east of London consisting of several hundred turbines. To design such a farm optimally it is necessary to understand the chaotic and very turbulent flow downwind from a turbine, which decreases the power production and increases the mechanical loads on other nearby turbines.

    The Bald and Golden Eagle Protection Act (BGEPA) prohibits the 'take' of these birds. The act defines take as to 'pursue, shoot, shoot at, poison, wound, kill, capture, trap, collect, destroy, molest or disturb.' The 2009 Eagle Permit Rule (74 FR 46836) authorizes the U.S. Fish and Wildlife Service (USFWS) to issue nonpurposeful (i.e., incidental) take permits, and the USFWS 2013 Eagle Conservation Plan Guidance provides a voluntary framework for issuing programmatic take permits to wind facilities that incorporate scientifically supportable advanced conservation practices (ACPs). Under these rules, the Service can issue permits that authorize individual instances of take of bald and golden eagles when the take is associated with, but not the purpose of, an otherwise lawful activity, and cannot practicably be avoided. To date, the USFWS has not approved any ACPs, citing the lack of evidence for 'scientifically supportable measures.' The Eagle Detection and Deterrents Research Gaps and Solutions Workshop was convened at the National Renewable Energy Laboratory in December 2015 with a goal to comprehensively assess the current state of technologies to detect and deter eagles from wind energy sites and the key gaps concerning reducing eagle fatalities and facilitating permitting under the BGEPA. During the workshop, presentations and discussions focused primarily on existing knowledge (and limitations) about the biology of eagles as well as technologies and emerging or novel ideas, including innovative applications of tools developed for use in other sectors, such as the U.S. Department of Defense and aviation. The main activity of the workshop was the breakout sessions, which focused on the current state of detection and deterrent technologies and novel concepts/applications for detecting and minimizing eagle collisions with wind turbines. Following the breakout sessions, participants were asked about their individual impressions of the

    France is currently engaged in the energy transition where ambitious goals are at stake to allow the country to be one of the leading European countries in renewable energies. The cost of onshore wind is getting more and more competitive and for this reason, wind energy professionals are committed in contributing actively to reach the 32 % objective of renewable energies in the final energy consumption and 40 % of renewable energies in the electricity mix for 2030. 2014 was marked by a swift growth of the installed onshore wind energy, the positive trend is confirmed in 2015 with more than 500 MW connected to the grid in the first half of the year, corresponding to the annual forecast of 1,200 MW for 2015. Thanks to the energy transition law, operational policies will be implemented through the multi-annual energy programming (PPE- programmation pluriannuelle de l'energie). France will therefore continue increasing its development of renewable energies. This law will also allow France to develop offshore wind energy and to strengthen its position regarding wind energy: with an objective of 15 GW of fixed offshore wind energy and 6 GW of floating wind energy to be built in the 2030 horizon, the sector will be able to guarantee its development, especially in the current context of strong worldwide competition. Some 10,000 direct and indirect jobs are awaited for offshore wind energy on the national territory and wind energy professionals underline that the development of the offshore wind sector will contribute to the economic dynamism of the country. This sector is thus a job creating sector as confirmed in the figures of the wind employment monitor (observatoire de l'emploi) in France, recording a significant growth in 2013 with 10,800 jobs. This upward trend was confirmed in 2014. This proves the continuous commitment of the wind industry in seeing the success of the energy transition in France in a context marked by numerous energy and climate events

A consortium (KWEC – Kansas Wind Energy Consortium) of researchers from Kansas State University and Wichita State University aims to dramatically increase the penetration of wind energy via distributed wind power generation. We believe distributed generation through wind power will play a critical role in the ability to reach and extend the renewable energy production targets set by the Department of Energy. KWEC aims to find technical and economic solutions to enable widespread implementation of distributed renewable energy resources that would apply to wind.

    This document was prepared as part of a decentralized collaboration between Quebec and France to share knowledge regarding strategies and best practices in wind power development. It reviewed the social acceptance of Quebec's wind power industry, particularly at the municipal level. The wind industry is growing rapidly in Quebec, and this growth has generated many reactions ranging from positive to negative. The purpose of this joint effort was to describe decision making steps to developing a wind turbine array. The history of wind development in Quebec was discussed along with the various hardware components required in a wind turbine and different types of installations. The key element in implementing wind turbine arrays is to establish public acceptance of the project, followed by a good regulatory framework to define the roles and responsibilities of participants. The production of electricity from wind turbines constitutes a clean and renewable source of energy. Although it is associated with a reduction in greenhouse gas emissions, this form of energy can also have negative environmental impacts, including noise. The revenues generated by wind parks are important factors in the decision making process. Two case studies in Quebec were presented. refs., tabs., figs.

    1987-01-01

    The wind energy conversion system includes a wind machine having a propeller connected to a generator of electric power, the propeller rotating the generator in response to force of an incident wind. The generator converts the power of the wind to electric power for use by an electric load. Circuitry for varying the duty factor of the generator output power is connected between the generator and the load to thereby alter a loading of the generator and the propeller by the electric load. Wind speed is sensed electro-optically to provide data of wind speed upwind of the propeller, to thereby permit tip speed ratio circuitry to operate the power control circuitry and thereby optimize the tip speed ratio by varying the loading of the propeller. Accordingly, the efficiency of the wind energy conversion system is maximized.

    1992-02-01

    Interest in wind energy as a supplementary source for the production of electricity has recently gained renewed momentum due to widespread concern about environmental impacts from the large scale use of fossil fuels and nuclear energy. In addition, political unrest in the Middle East has drawn attention to the importance of national energy self-sufficiency. European government administrations, however, have not yet fully appreciated the real worth of the 'clean energy' afforded by wind energy. In this regard, the European Wind Energy Association (EWEA) is acting as a strong voice to inform the public and energy planners by stimulating international wind energy R ampersand D cooperation, and organizing conferences to explain the advantages of wind energy. In October 1991, EWEA published a strategy document giving a picture of the real possibilities offered by wind energy within the geographical, social, and European economic context. This paper provides an overview of the more significant features to emerge from this document which represents a useful guideline for wind power plant technical/economic feasibility studies in that it contains brief notes on resource availability, land requirements, visual and acoustic impacts, turbine sizing, performance, interconnection to utility grids, maintenance and operating costs, safety, as well as, on marketing aspects

    The purpose of this project was to develop surface treatments which will inhibit the formation of ice on turbine blades and propellers. ORNL worked with Piedmont Propulsion Systems, LLC and First Aviation Services Inc. to demonstrate a new surface treatment for two primary markets, aviation and wind turbines, as well as secondary markets such as power lines, bridges, boats, roofs and antennas among others. Exploring alternative surface treatments for wind turbines will provide anti-icing properties and erosion/abrasion prevention properties similar to those for aviation applications. A series of superhydrophobic coating materials was synthesized and successfully applied on anti-ice tape materials that could be used in a wide range of wind turbine and aviation applications to prevent ice accumulation. The coatings developed in this project were based on superhydrophobic particles of different geometries and sizes that were homogeneously dispersed in polymeric binders. The superhydrophobic features of the coatings are volumetric and their abrasion resistance was evaluated. Future research will involve the demonstration of anti-icing properties of the surface treatment developed in this project.

  2. Suitability analysis of wind energy development on brownfields, landfills and industrial sites in the city of Chicago

    Science.gov (United States)

    Fyodorova, Valeryia A.

    In 2011 renewable energy generated only about 5% of total U.S. electricity and 3% came from wind power. Wind power is the oldest and fastest growing renewable energy, and U.S. Department of Energy (DOE) anticipates that by 2030 the potential of the U.S. to generate wind power will rise up to 20% (National Renewable Energy Laboratory 2008). Currently, the rural areas serve as the primary choice of wind turbine installation because there are less wind obstacles that create wind turbulence, which in turn is disruptive for the proper functioning of the wind turbines, and allows more laminar (streamline) wind flow. However according to various literatures, the installation of wind turbines in rural areas has its drawbacks. The infrastructure is underdeveloped and usually the selected sites require the construction of new roads and transmission lines. The new construction and occasional deforestation lead to soil erosion and environmental degradation. On top of that transporting energy to cities that are the primary consumers of wind energy results in energy transmission loss. Urban areas, on the other hand, have well developed infrastructure, and the installation of turbines on abandoned and contaminated urban lands which are expensive to clean and rehabilitate for other uses would lower installation costs and would have little environmental degradation effect. The objective of this research was to provide a preliminary wind power suitability analysis for installing medium (100 -1000 kW) and large (1000 - 3000 kW) size wind turbines in urban areas, such as city of Chicago. Geographic Information Systems (GIS) and a multi attribute Weighted Linear Combination (WLC) method that is based on the concept of weighted average were primary tools utilized to conduct the analysis. The criteria that were used to select suitable sites were the same criteria used for rural wind farms, such as wind speeds, historic landmarks, avian and wildlife habitat, conservation lands, proximity

    This report is a valuable tool for members of the wind industry and policy makers alike to learn about the market opportunities and the legal and regulatory framework in India. In addition, it gives us insights into the challenges going forward and offers suggestions for overcoming remaining hurdles for wind power development. According to the outlook 65.2 GW of wind power could be installed in Indian by 2020, up from 13.1 GW at the end of 2010. This would attract around USD 10.4bn of annual investment to the sector, and create 170,000 'green collar' jobs in manufacturing, project development, installation, operation, maintenance, consulting etc. At the same time, it would save 174 tons of CO2 every year. By 2030, the installed capacity could reach as much as 160.7 GW. In order to fully exploit the indigenous energy source at its doorstep, the Indian government needs to address several challenges and barriers that are holding back development. This includes a national renewable energy law, incentives for repowering, and rapid up-scaling of grid infrastructure to transport increasing amounts of wind power to the demand centres. It highlights the key role wind power could play in fueling India's growing energy demand, by delivering substantial amounts of clean energy.

    Issues concerning the social acceptance of wind energy are major challenges for policy-makers, communities and wind developers. They also impact the legitimacy of societal decisions to pursue wind energy. Here we set out to identify and assess the factors that lead to wind energy disputes in Ontario, Canada, a region of the world that has experienced a rapid increase in the development of wind energy. Based on our expertise as a group comprising social scientists, a community representative and a wind industry advocate engaged in the Ontario wind energy situation, we explore and suggest recommendations based on four key factors: socially mediated health concerns, the distribution of financial benefits, lack of meaningful engagement and failure to treat landscape concerns seriously. Ontario's recent change from a feed-in-tariff-based renewable electricity procurement process to a competitive bid process, albeit with more attention to community engagement, will only partially address these concerns.

    The global energy requirement for sustaining economic activities, meeting social needs and social development is increasing daily. Environmentally friendly, renewable energy resources are an alternative to the primary non-renewable energy resources, which devastate ecosystems in order to meet increasing demand. Among renewable energy sources such as hydropower, biopower, geothermal power and solar power, wind power offers distinct advantages to Turkey. There is an increasing tendency toward wind globally and the European Union adjusted its legal regulations in this regard. As a potential EU Member state, Turkey is going through a similar process. The number of institutional and legal regulations concerning wind power has increased in recent years; technical infrastructure studies were completed, and some important steps were taken in this regard. This study examines the way in which Turkey has developed support for wind power, presents a SWOT analysis of the wind power sector in Turkey and a projection was made for the concrete success expected to be accomplished in the future.

    Triodos Bank has more than 10 years of experience with developing and financing wind projects in the Netherlands. Over 50 Megawatt has been installed with direct involvement of the bank. The experience is both as a bank and as a venture capital fund. In this contribution the perspective will be more from a venture capital point of view than as a bank. The bank's activities in the wind energy sector started in 1986 by forming a joint venture with an engineering bureau, experienced i wind energy but not yet in developing wind projects. From 1989 onwards the joint venture started to build wind farms, both as a private company and in a joint venture with utilities. The European Investment Bank became involved with a long-term debt finance facility (15 years, fixed interest loan). The main difficulties were long-term commitments from landowners (Dike authorities) and utilities with regard to power contracts. The development got really stuck when utilities refused to pay a fair price anymore. Also, site development became more and more difficult. Even the poor technical performance improved drastically and did not frighten developers and banks too much. (author)

    Swainson’s hawks (Buteo swainsoni) are a long-distance migratory species that breed in western North America and winter in Argentina. As a grassland species, they can also be found in agricultural settings, such as croplands and pastures. Wind energy is expanding rapidly across the breeding range of the population we chose to study, and we suspect the industry is also expanding in their wintering range and across the migratory pathway. Wind turbines pose a threat to birds, and migratory species may be especially susceptible to turbine-related mortality when these structures are placed in important migratory pathways. The purposes of this longterm study were to examine potential threats that wind energy might pose to Swainson’s hawks on the breeding range, wintering range, and during migration, add to the body of ecological knowledge on migration and wintering habits, and describe breeding habits in a portion of their range that is relatively understudied.

    Since 2010, the ADEME has been managing four programmes within the scope of 'Future Investments'. Groups of research experts from various industrial fields, research bodies and research programming and financing agencies are responsible, within the scope of collective works, for producing strategic road-maps. These are used to launch Calls for Expressions of Interest (CEI). With regard to wind energy, the purpose of this road-map is to: - Highlight the industrial, technological, environmental and societal challenges encountered in the development of 'Industrial Wind'; - Draw up middle and long-term coherent, shared visions of the socio-technical systems or technologies in question; - Identify the technological, organisational, environmental and socio-economic obstacles, and therefore initiate (or pursue) the development of high-performance and economically viable technologies; - Promote the research, development and demonstration requirements ('technological demonstrators' to validate innovative technological solutions), experimentation requirements and technology platforms to be deployed ('pilot' projects to be tested under real circumstances: 'pre-commercial' unit prototypes then 'pre-commercial pilot farms') to improve the competitiveness of offers and companies within this sector, to reach the ambitious objectives set within the framework of the Grenelle Environnement and to promote and support the development of a French wind energy industry. These needs can then act as a basis for: - drawing up CEIs; - programming research within the ADEME and other institutions such as the Agence nationale de la recherche (ANR - French National Research Agency), the Comite strategique national sur la recherche energie (French national strategic committee for energy research) and the Alliance nationale de coordination de la recherche pour l'energie (ANCRE - French national alliance for the coordination of energy

    Following the request for proposal (RFP)-fueled explosion in renewable energy source development over the past 3 years, independent power producer (IPP) financial expertise has become critical to successful project implementation. This presentation reviewed aspects of Canadian wind market related to independent power producer (IPP) investment activity. A map of major Canadian wind farms operational at the end of 2005 was provided, as well as a map of provinces with utility RFP activity. Planned projects were listed by MW. Recent provincial RFP winners were listed. It was suggested that project execution experience and financial security were highly valued in the recent Hydro-Quebec and Ontario RFP solicitations. Developer consolidation and scaling is likely to continue as large wind IPPs are in the best position to maximize efficiency gains in project economics. Financial strength will continue to be key to winning provincial wind RFPs, and Quebec and Ontario RFPs are likely to be dominated by players with balance sheet security. Smaller developers are losing their competitive position in RFP negotiations as more national and international energy giants move into the wind industry. The consolidation trend is ramping up quickly, and may be closing the window in which international investors can find acquisition targets with experience and viable projects. It was concluded that while small developers with robust projects still exist, they are being acquired at a rapid rate. refs., tabs., figs

  15. Valuation of switchable tariff for wind energy

    International Nuclear Information System (INIS)

    Yu, Wang; Sheble, Gerald B.; Lopes, Joao A. Pecas; Matos, Manuel Antonio

    2006-01-01

    The current fixed tariff remuneration for wind energy is not compatible with the deregulation of the electric power industry. The time-varying and location-dependent value of renewable energy is not acknowledged. The newly announced switchable tariff for wind energy in the Spanish electricity market provides a promising solution to compensating renewable energy within the deregulated electric power industry. The new switchable tariff provides wind generators more flexibility in operating wind generation assets. Such flexibilities provide option value in coordinating the seasonality of wind energy, demand on electric power and electricity prices movement. This paper models and valuates the flexibility on switching tariff as real compound options for wind generators. Numerical examples valuate wind generation assets under fixed tariff, spot market price taking, and yearly and monthly switchable tariffs. The optimal switching strategies are identified. The impacts of the switchable tariff on sitting criteria and values of wind generation assets are investigated. An improvement on the yearly switchable tariff is suggested to further reduce the operation risk of wind generators and fully explore the efficiency provided by competitive electricity markets.

    2017-04-01

    Full Text Available The competition of maintenance services in the offshore wind industry is continually increasing. The quality of the services acts as the distinguishing feature in the industry. Furthermore, there are public standards, which lead to the permanent necessity to offer further education and training programs for employees. To meet the requirements for further training in the specific field of application within the offshore wind industry, a gamified e-learning application has been developed and is introduced in this paper. It consists of a complete solution, which contains the automated analysis of service protocols to identify qualification needs, the involvement of service technicians in the generation of learning materials, the preparation, transmission as well as the further development of those materials in accordance with the principles of e-learning. Finally, the solution contains a gamified mobile application for qualification, which is designed to meet the individual learning needs of the service technicians. This concept paper follows a problem-centred approach. Based on the current state of technology and research, the problem and motivation are identified and the urgency is verified. Furthermore, a detailed specification of the solution and a first implementation approach is presented.

  18. Bird Killer, Industrial Intruder or Clean Energy? Perceiving Risks to Ecosystem Services Due to an Offshore Wind Farm

    KAUST Repository

    Klain, Sarah C.

    2017-07-19

    Proposals to develop renewable energy technologies may threaten local values, which can generate opposition. Efforts to explain this opposition have focused on perceived negative aesthetic and environmental impact. Less attention has been paid to a fuller suite of the perceived risks and benefits associated with new energy technologies. This paper thus investigates impacts of an offshore wind farm pertaining to individual perceptions and judgments, and why risks to some ecosystem services might be cause for greater public concern than others. We find that this difference can be attributed to the affective and intuitive ways in which people perceive risk. Our mixed-methods design used interviews (n=27) that involved risk-benefit weighting tasks and an animated visualization to help people imagine an offshore wind farm in a familiar place. We found that affectively-loaded impacts (harm to charismatic wildlife and visual intrusion) were assigned greater weight than more easily quantifiable impacts (displacement of fishing, impact to tourism, cost of compliance with regulations). Interviewees identified increased regional energy self-sufficiency as the most valued potential benefit of an offshore wind farm. These results have implications for ecosystem service assessments generally and, more specifically, for our understanding of ‘affective’ dimensions of development proposals.

    The politics and economics of wind energy have played an important role in the development of the industry and contributed to its present success. Engineering is, however, pivotal. As the wind industry has become better established, the central place of engineering has become overshadowed by other issues. This is a tribute to the success of the engineers and their turbines. This volume addresses the key engineering Issues: 1) The turbines - their past achievements and future challenges - a remarkable tale of technical endeavour and entrepreneurship. 2) The wind - its characteristics and reliability - how can it be measured, quantified and harnessed? 3) The wind farms - an assembly of individual turbines into wind power stations or wind farms - their optimisation and development. 4) The grid - transporting the energy from remote locations with plentiful wind energy to the loads - the key technical and strategic challenges. This volume provides an historical overview of turbine development, describes the present status and considers future challenges. This is a remarkable story starting in the nineteenth century and then accelerating through the last two decades of the twentieth century on a course very similar to the early days of aeronautics. The story is far from finished but it has certainly started with a vengeance. Wind must be treated with great respect. The speed of the wind on a site has a very powerful effect on the economics of a wind farm; it provides both the fuel to generate electricity and the loads to destroy the turbine. This volume describes how it can be quantified, harnessed and put to work in an economic and predictable manner. The long-term behaviour of the wind is described as well as its short-term behaviour. The latter can be successfully forecast to allow wind energy to participate in electricity markets. In order for wind to live up to its raw potential promise, individual turbines must be assembled into wind farms or wind power stations

    Wind energy research has two goals: (1) to gain a fundamental understanding of the interactions between wind and wind turbines; and (2) to develop the basic design tools required to develop advanced technologies. A primary objective of applied research activities is to develop sophisticated computer codes and integrate them into the design, testing, and evaluation of advanced components and systems, Computer models have become a necessary and integral part of developing new high-tech wind energy systems. A computer-based design strategy allows designers to model different configurations and explore new designs before building expensive hardware. DOE works closely with utilities and the wind industry in setting its applied research agenda. As soon as research findings become available, the national laboratories transfer the information to industry through workshops, conferences, and publications.

It describes this development as a rather disordered one in terms of pricing, in terms of land planning and of preservation of landscapes, sites and other activities. It outlines some technical problems which are still to be solved: connection to the network, intermittent production and prediction issues. It briefly presents choices made in Denmark. Some issues are then discussed for a better controlled development: a strengthened public policy, a better acceptance by the population.

    On March 12th, 2004 the Spanish Government modified the legal situation of the renewable energies following the approval of RD 436/2004. This makes necessary the development of wind energy prediction models for its entrance to the daily electricity market like the conventional energies. The improvement of physical models, meteorological models, or a combination of both, is necessary for the prediction of the wind generation. This will guarantee the wind energy full utilization and the participation in the electrical market, as well as the remuneration of the complementary services and the regulation of reactive electricity. In this way wind energy turns into a perfectly manageable one. (Author)

  18. Wind energy in Germany

    International Nuclear Information System (INIS)

    Molly, J.P.

    1994-01-01

    End of June 1994 429 MW in about 2100 wind energy converters (WECs) have been installed in Germany, able to produce 1.1% of the electrical energy demand of the five German coastal states Lower Saxony, Bremen, Hamburg, Schleswig-Holstein and Mecklenburg-Vorpommern. Determining factor for the again increased installation rate, compared with 1993, is the new 500/600-kW-class which now dominates the market. Dramatically reduced WEC prices during the last two years now allow an economic operation in good wind speed regions even without any subsidy. The goal to reach a total of 2000 MW WEC installations in the year 2000 is suddenly near at hand. In the course of the next seven years an installation rate of 250 MW/year will be necessary, a value which could be reached already in 1994. Nevertheless, there still is a long way to go, if the 2000 MW shall be achieved in the year 2000. New obstacles have arisen due to the increasingly restrictive handling of WEC site permission by conservationists, often in discrepancy with the generally recognized global ideas of the eco-organizations. After more than two years of experience, the WEC quality dependent subsidy as applied in Lower Saxony proofs to be a very effective stimulation for the technical development. WECs are now optimized for maximum energy production and minimum noise emission. The new 500/600-kW class is only half as noisy as could be expected from an extrapolation based on smaller WEC units. The energy cost reduction with the size of the WECs is still going on, indicating that the new Megawatt-WECs in development can offer again an economic advantage for the operator. (orig.)

  20. Wind energy developments in the Americas

    International Nuclear Information System (INIS)

    Swisher, R.; Ancona, D.F.

    1990-01-01

    This paper will highlight the key wind energy activities and programs of American countries. In South and Central America, wind technology awareness and opportunity is spreading. Countries have projects in the beginning stages of development and many sites with excellent wind resources are believed to exist. Argentina, Costa Rica, Colombia, Mexico, and several Caribbean countries are among those active in wind energy development. In Canada, after a decade of research and systems development, the Department of Energy Mines and Resources is conducting a review of all renewable energy technologies, including wind, to develop a strategic plan for future activities. Canadian industry continues development of various vertical axis projects and the Province of Alberta has begun a program to assess wind potential in that region. In the United States, commercial application of wind energy is continuing to expand. During 1989, over 140 MW of new wind turbine capacity was installed in wind power plants, bringing the total operating in the U.S. to 14600 turbines and 1,400 MW. During 1989, these machines produced over 2.1 billion kWh, enough to supply the residential needs of Washington D.C. or San Francisco. This is an increase of 15% over the 1988 total, even though installed operating capacity dropped by about 10% as smaller, out-dated turbines were phased out or replaced. The U.S. government is in the process of formulating a new National Energy Strategy. It seems clear that renewable energy and energy efficiency will play an increasingly important role in this strategy. The U.S. wind program continues to emphasize broad-based technology development, but has also initiated conceptual design studies for an advanced wind turbine for power generation in the late 1990s.

    In support of the U.S. Department of Energy (DOE) Wind and Water Power Technologies Office (WWPTO) goals, researchers from DOE's National Renewable Energy Laboratory (NREL), National Wind Technology Center (NWTC) are investigating the Distributed Wind Resource Assessment (DWRA) process, which includes pre-construction energy estimation as well as turbine site suitability assessment. DWRA can have a direct impact on the Wind Program goals of maximizing stakeholder confidence in turbine performance and safety as well as reducing the levelized cost of energy (LCOE). One of the major components of the LCOE equation is annual energy production. DWRA improvements can maximize the annual energy production, thereby lowering the overall LCOE and improving stakeholder confidence in the distributed wind technology sector by providing more accurate predictions of power production. Over the long term, one of the most significant benefits of a more defined DWRA process could be new turbine designs, tuned to site-specific characteristics that will help the distributed wind industry follow a similar trajectory to the low-wind-speed designs in the utility-scale industry sector. By understanding the wind resource better, the industry could install larger rotors, capture more energy, and as a result, increase deployment while lowering the LCOE. a direct impact on the Wind Program goals of maximizing stakeholder confidence in turbine performance and safety as well as reducing the levelized cost of energy (LCOE).

    1995-01-01

    Though located in the tropics, India is endowed with substantial wind resources because of its unique geographical location which gets fully exposed to both the south-west and north-east monsoon winds. The westerly winds of the south-west monsoons provide bulk of the wind potential. Areas with mean annual wind speed exceeding 18 k mph and areas with mean annual power density greater than 140 W/m 2 have been identified using the wind data collected by the wind monitoring project funded by the Ministry of Non-conventional Energy Sources (MNES). Seasonal variations in wind speed at selected locations are discussed as also the frequency distribution of hourly wind speed. Annual capacity factors for 250 kW wind electric generators have been calculated for several typical locations. A good linear correlation has been found between mean annual wind speed and mean annual capacity factor. A method is described for assessing wind potential over an extended region where adequate data is available. It is shown that the combined wind energy potential over five selected areas of limited extent in Gujarat, Andhra Pradesh and Tamil Nadu alone amounts to 22,000 MW under the assumption of 20 per cent land availability for installing wind farms. For a higher percentage of land availability, the potential will be correspondingly higher. (author). 12 refs., 6 figs., 3 tabs

    2010-01-01

    With the increasing negative effects of fossil fuel combustion on the environment in addition to limited stock of fossil fuel have forced many countries to inquire into and change to environmentally friendly alternatives that are renewable to sustain the increasing energy demand. Energy policy plays a vital role to mitigate the impacts of global warming and crisis of energy availability. This paper explores the wind energy industry from the point of view of the wind energy policy. It is noticed that energy policy could help increasing wind power generation as well as stimulating the energy industry. It may be stated that without specific energy policy, a country would not be able to solve the acute problems like reducing greenhouse gases (GHGs) emission, scarcity of energy, etc. This paper discussed the existing successful energy policies for few selected countries. Based on literatures, it has been found that FIT, RPS, incentives, pricing law and Quota system are the most useful energy policies practiced by many countries around the world. Then, status of wind energy policy for Malaysia was investigated and compared with few selected countries around the world. (author)

    Reductions in the cost of producing wind energy are helping to make this renewable energy source competitive with conventional energy sources. The market for this type of energy in Italy, however, hasn't yet gained a foothold even though close examination of Italy's geomorphology reveals that this country is in fact endowed with many areas having good potential for wind power production. This paper discusses the measures to be taken to bolster wind energy commercialization efforts in Italy. It provides a brief assessment of the current state of wind power technology, national and international market trends, and the directions being taken by other national governments to promote wind turbine manufacturing industries and applications. The comparative analysis indicates that in order to have this energy source alternative taken seriously as an economically viable energy option in Italy, greater financial assistance should be given to local manufacturers involved in commercialization efforts. In addition, a suitable rate structure should be created favouring wind power by taking into account cost benefits afforded by this renewable energy source in terms of reduced air pollution, as well as, reduced national dependency on foreign energy imports

  16. Overview of Existing Wind Energy Ordinances

    2008-12-01

    Due to increased energy demand in the United States, rural communities with limited or no experience with wind energy now have the opportunity to become involved in this industry. Communities with good wind resources may be approached by entities with plans to develop the resource. Although these opportunities can create new revenue in the form of construction jobs and land lease payments, they also create a new responsibility on the part of local governments to ensure that ordinances will be established to aid the development of safe facilities that will be embraced by the community. The purpose of this report is to educate and engage state and local governments, as well as policymakers, about existing large wind energy ordinances. These groups will have a collection of examples to utilize when they attempt to draft a new large wind energy ordinance in a town or county without existing ordinances.

  17. Innovation and the price of wind energy in the US

    International Nuclear Information System (INIS)

    Berry, David

    2009-01-01

    In the last ten years, the wind energy industry has experienced many innovations resulting in wider deployment of wind energy, larger wind energy projects, larger wind turbines, and greater capacity factors. Using regression analysis, this paper examines the effects of technological improvements and other factors on the price of wind energy charged under long-term contracts in the United States. For wind energy projects completed during the period 1999-2006, higher capacity factors and larger wind farms contributed to reductions in wind energy contract prices paid by regulated investor owned utilities in 2007. However, this effect was offset by rising construction costs. Turbine size (in MW) shows no clear relationship to contract prices, possibly because there may be opposing factors tending to decrease costs as turbine size increases and tending to increase costs as turbine size increases. Wind energy is generally a low-cost resource that is competitive with natural gas-fired power generation.

    The amendments put down at the French house of commons and at the senate to the energy orientation law will, if adopted, lead to the abandonment of about 95% of the wind energy projects (about 2500 MW). The minimum power to profit by the obligation of power purchase by Electricite de France or by local distribution companies is increased to 20 MW in order to favour the big structures and to protect the landscapes. This disposition is considered as catastrophic by the wind energy professionals and will lead to important geographical disparities between densely and weakly populated regions. In Germany, which is the first European wind power producing country with 160000 MW installed, the development of wind energy represents prohibitive investments. Nevertheless, Germany is now staking on offshore wind power. The first offshore wind farms will be put into service in 2006 in the Baltic sea. (J.S.)

    The energy policy of the Dutch government is aimed at the use of different energy sources (diversification). Therefore the Dutch government supports the implementation of wind turbines and stimulates product improvement and research by means of the TWIN-program (a program to support the application of wind energy in the Netherlands). The purpose of the program is to commercialize efficient wind turbines. Without subsidies it is not yet possible to exploit wind turbines in an efficient way. Around the year 2000 a capacity of 1000 MW must be realized. 1 fig., 1 ill., 5 tabs., 1 ref

    2015-11-04

    This project developed relationships among the lead institution, U of Delaware, wind industry participants from 11 companies, and two other universities in the region. The participating regional universities were University of Maryland and Old Dominion University. Research was carried out in six major areas: Analysis and documentation of extreme oceanic wind events & their impact on design parameters, calibration of corrosivity estimates measured on a coastal turbine, measurment and modeling of tower structures, measurement and modeling of the tribology of major drive components, and gearbox conditioning monitoring using acoustic sensors. The project also had several educational goals, including establishing a course in wind energy and training graduate students. Going beyond these goals, three new courses were developed, a graduate certificate program in wind power was developed and approved, and an exchange program in wind energy was established with Danish Technical University. Related to the installation of a Gamesa G90 turbine on campus and a Gamesa-UD research program established in part due to this award, several additional research projects have been carried out based on mutual industry-university interests, and funded by turbine revenues. This award and the Gamesa partnership have jointly led to seven graduate students receiving full safety and climb training, to become “research climbers” as part of their wind power training, and contributing to on-turbine research. As a result of the educational program, already six graduate students have taken jobs in the US wind industry.

    1995-01-01

    At the British Wind Energy Association's 16th Annual Conference, held in Stirling, over 60 high quality papers were presented, including a session devoted to 'Wind Energy in Scotland'. Under the Non Fossil Fuel Obligation (NFFO) wind energy has experienced rapid growth in England and Wales and with Scotland now having its own 'Scottish Renewables Obligation' (SRO) the opportunity to tap one of Europe's most important renewable energy resources now exists. The main contemporary issues concerning wind farming today, namely technical, social, economic and environmental were examined in the Geoff Pontin Memorial Lecture, which focused on these aspects in the context of grid integrated wind energy development. The remaining conference themes included machine development, aerodynamics and control, small machines, fatigue and dynamics, public attitudes, noise emissions, electrical integration, resource measurement, and standards, safety and planning.

  7. Wind energy - The facts. An analysis of wind energy in the EU-25

    International Nuclear Information System (INIS)

    2004-02-01

    Since the previous edition of Wind Enera - The Facts was published five years ago, the wind energy sector has undergone rapid change and transformation. There has been an explosion in demand for and Interest in a cleaner energy world from politicians, institutions, policy makers and regulators, the media, commentators and the general public. Such interest necessitates a greater depth of understanding of the wind power sector if informed choices and policy decisions are to be made. The European Wind Energy Association (EWEA), and the European Commission's Directorate General for Transport' and Energy have collaborated on this report to provide a detailed overview of the wind power sector. Wind Enera - The Facts provides a comprehenslve overview of the essential issues concerning wind power today: technology, cost, prices, environment, industry and employment, market, and research and development. Wind energy is a relatively young but rapidly expanding industry. Over the past decade, global installed capacity has increased from 2,500 megawatts (MW) in 1992 to just over 40,000 MW at the end of 2003, at an annual growth rate of near 30%. Almost three quarters of this capacity has been installed in Europe. Penetration levels in the electricity sector have reached 20% in Denmark and about 5% in both Germany and Spain. The north German state of Schleswig-Holstein has 1,800 MW of installed wind capacity, enough to meet 30% of the region's total electricity demand, while in Navarra, in Spain, 50% of consumption is met by wind power. If positive policy support continues to develop, EWEA has projected that wind power will achieve an installed capacity of 75,000 MW in the EU-15 by 2010. This would represent an overall contribution to electricity supply of 5.5%. By 2020, this figure is expected to increase to more than 12%, with wind power providing energy equal to the demand of 195 million European household consumers. (au)

    2008-07-01

    This document was prepared as part of a decentralized collaboration between Quebec and France to share knowledge regarding strategies and best practices in wind power development. It reviewed the social acceptance of Quebec's wind power industry, particularly at the municipal level. The wind industry is growing rapidly in Quebec, and this growth has generated many reactions ranging from positive to negative. The purpose of this joint effort was to describe decision making steps to developing a wind turbine array. The history of wind development in Quebec was discussed along with the various hardware components required in a wind turbine and different types of installations. The key element in implementing wind turbine arrays is to establish public acceptance of the project, followed by a good regulatory framework to define the roles and responsibilities of participants. The production of electricity from wind turbines constitutes a clean and renewable source of energy. Although it is associated with a reduction in greenhouse gas emissions, this form of energy can also have negative environmental impacts, including noise. The revenues generated by wind parks are important factors in the decision making process. Two case studies in Quebec were presented. refs., tabs., figs.

  15. Assessing high wind energy penetration

    International Nuclear Information System (INIS)

    Tande, J.O.

    1995-01-01

    In order to convincingly promote installing wind power capacity as a substantial part of the energy supply system, a set of careful analyses must be undertaken. This paper applies a case study concentrated on assessing the cost/benefit of high wind energy penetration. The case study considers expanding the grid connected wind power capacity in Praia, the capital of Cape Verde. The currently installed 1 MW of wind power is estimated to supply close to 10% of the electric energy consumption in 1996. Increasing the wind energy penetration to a higher level is considered viable as the project settings are close to ideal, including a very capable national utility company, Electra, a conventional power supply system based on imported heavy fuel and gas oil, and favourable wind conditions with an estimated annual average of 9.3 m/s at the hub height of the wind turbines. With the applied case study assumptions, simulations with WINSYS over the lifetime of the assessed wind power investment show that investments up to 4.2 MW are economically viable. The economic optimum is found at 2.4 MW reaching an internal rate of return of almost 8% p.a. This 2.4 MW of wind power would, together with the existing wind power, supply over 30% of the electric consumption in 1996. Applying the recommended practices for estimating the cost of wind energy, the life-cycle cost of this 2.4 MW investment is estimated at a 7% discount rate and a 20 year lifetime to 0.26 DKK/kW h.

  16. Wind energy in France: impossible?

    International Nuclear Information System (INIS)

    Marie-Josette, R.

    2005-01-01

    Since the end of 2004, the European Union is the first producer of wind energy in the world (34205 MW), far beyond the USA (6740 MW) and India (2110 MW). Three countries are in the pole position: Germany (16629 MW), Spain (8263 MW) and Denmark (3117 MW). On the other hand, despite a voluntarist policy, the other countries encounter administrative and local difficulties in the development of wind energy. This is the case with France which has the second biggest potential wind resource of Europe, behind the UK. The French situation is explained by its centralized energy system, by the priority given to nuclear power, by important wind variations, and by a bad image of wind turbines in general (aesthetic, environmental). This situation should change in the future with the scheduling of pluri-annual investments, with adapted tariffs and with improved administrative procedures. (J.S.)

  4. Integrated roof wind energy system

    Directory of Open Access Journals (Sweden)

    Moonen S.P.G.

    2012-10-01

    Full Text Available Wind is an attractive renewable source of energy. Recent innovations in research and design have reduced to a few alternatives with limited impact on residential construction. Cost effective solutions have been found at larger scale, but storage and delivery of energy to the actual location it is used, remain a critical issue. The Integrated Roof Wind Energy System is designed to overcome the current issues of urban and larger scale renewable energy system. The system is built up by an axial array of skewed shaped funnels that make use of the Venturi Effect to accelerate the wind flow. This inventive use of shape and geometry leads to a converging air capturing inlet to create high wind mass flow and velocity toward a vertical-axis wind turbine in the top of the roof for generation of a relatively high amount of energy. The methods used in this overview of studies include an array of tools from analytical modelling, PIV wind tunnel testing, and CFD simulation studies. The results define the main design parameters for an efficient system, and show the potential for the generation of high amounts of renewable energy with a novel and effective system suited for the built environment.

    The European renewable energy industry has the potential to be a world leader. This has been achieved within the European region for specific technologies, through a set of policy activities at a national and regional level, driven primarily by employment, energy self-sufficiency and industrial competitiveness. Using the experience gained in recent years, European industry has the opportunity to continue to expand its horizons on a worldwide level. Through the use of the SAFIRE rational energy model, an assessment has been made of the future penetration of renewable energy within Europe and the effects on these socio-economic factors. In conjunction with these outputs, assessments of the worldwide markets for wind, photovoltaics, solar thermal plant and biomass have been assessed. A case study of the Danish wind industry is used as a prime example of a success story from which the learning opportunities are replicated to other industries, so that the European renewable energy industry can achieve its potential.

    Accurate forecasting of available energy is crucial for the efficient management and use of wind power in the national power grid. With energy output critically dependent upon wind strength there is a need to reduce the errors associated wind forecasting. The objective of this research is to get the best possible wind forecasts for the wind energy industry. To achieve this goal, three methods are being applied. First, a mesoscale numerical weather prediction (NWP) model called WRF (Weather Research and Forecasting) is being used to predict wind values over Ireland. Currently, a gird resolution of 10km is used and higher model resolutions are being evaluated to establish whether they are economically viable given the forecast skill improvement they produce. Second, the WRF model is being used in conjunction with ECMWF (European Centre for Medium-Range Weather Forecasts) ensemble forecasts to produce a probabilistic weather forecasting product. Due to the chaotic nature of the atmosphere, a single, deterministic weather forecast can only have limited skill. The ECMWF ensemble methods produce an ensemble of 51 global forecasts, twice a day, by perturbing initial conditions of a 'control' forecast which is the best estimate of the initial state of the atmosphere. This method provides an indication of the reliability of the forecast and a quantitative basis for probabilistic forecasting. The limitation of ensemble forecasting lies in the fact that the perturbed model runs behave differently under different weather patterns and each model run is equally likely to be closest to the observed weather situation. Models have biases, and involve assumptions about physical processes and forcing factors such as underlying topography. Third, Bayesian Model Averaging (BMA) is being applied to the output from the ensemble forecasts in order to statistically post-process the results and achieve a better wind forecasting system. BMA is a promising technique that will offer calibrated

    2010-01-01

    Offshore wind energy developments are expected to increase as the demand for renewable energy sources grows. This poster presentation described a method of balancing risk and reward in offshore wind energy projects. The method was based on risk assessment strategies used by the oil and gas industry. The dedicated framework considered schedules; budgets; performance; and operating and maintenance costs. A value chain assessment method was used to optimize the balance between risk and reward by evaluating uncertainties and risk related to each project element and its relationship to other elements within an integrated dynamic model designed to determine the net present value of a project. The decision-making criteria included the RISKEX risk expenditure strategy designed to consider the balance between risk exposure, capital expenditures, and operational expenditures in relation to the statistical cost of unplanned repairs, and lost production capacity. A case study of a large offshore wind farm was used to demonstrate the method. tabs., figs.

    2009-01-01

    The growing demand in energy and concern about depleting natural resources and global warming has led states worldwide to consider alternatives to the use of fossil fuel for energy production. Several countries especially in Europe have already increased their renewable energy share 6-10%, expected to increase to 20% by the year 2020. For Egypt excellent resources of wind and solar energy exist. The article discusses perspectives of wind energy in Egypt with projections to generate ∼ 3.5 GWe by 2022, representing ∼ 9% of the total installed power at that time (40.2 GW). Total renewable (hydro + wind + solar) are expected to provide ∼ 7.4 GWe by 2022 representing ∼ 19% of the total installed power. Such a share would reduce dependence on depleting oil and gas resources, and hence improve country's sustainable development

    2005-01-01

    Sound and vibration are considered to be pollutants. This paper provides an outline of sound guidelines and their relationship to wind energy and Ontario's Environmental Protection Act, which prohibits the discharge of noises that cause or are likely to cause adverse effects. Certificates of approval are needed for wind turbine generators. The approval process is detailed in this paper, referring to existing limits in urban and rural areas, with sound level limits being based on the source producing the same sound level as background ambient sound levels. Background sound levels included traffic and nature as well as wind. For wind turbines, the ambient is related to the wind induced level by adding 7 decibels to the wind induced background sound level in exposed areas. Points of reception are considered to be locations outdoors where a person may be exposed to the sound or the plane of an exterior door or window of a room in which a person may be exposed to the sound, where the door or window is open. Sound limits apply within a distance of 30 m from a dwelling or camping area in a rural area, with the exception being dwellings on the premises of the wind energy facility. Certificate of Approval report requirements are also necessary and must include test results of turbines proposed in terms of sound power at the operating speeds to be used, as well as calculations of sound levels at points of reception, using an ISO 9613 sound propagation model. It is stated that there are no requirements to conduct an acoustic audit after the wind farm is in operation, should no complaints arise. Noise waivers are not supported by the Ontario Ministry of Energy. However, it was noted that the wind power industry are free to pursue this matter on a political level. tabs., figs

    The Comunidad Autonoma de Madrid (Autonomous Community of Madrid, in the following Madrid Region), is a region located at the geographical centre of the Iberian Peninsula. Its area is 8.028 km{sup 2}, and its population about five million people. The Department of Economy and Technological Innovation of the Madrid Region, together with some organizations dealing on energy saving and other research institutions have elaborated an Energy Plan for the 2004-12 period. As a part of this work, the Fluid Mechanics Laboratory of the Superior Technical School of Industrial Engineers of the Polytechnic University of Madrid has carried out the assessment of the wind energy resources [Crespo A, Migoya E, Gomez Elvira R. La energia eolica en Madrid. Potencialidad y prospectiva. Plan energetico de la Comunidad de Madrid, 2004-2012. Madrid: Comunidad Autonoma de Madrid; 2004]; using for this task the WAsP program (Wind Atlas Analysis and Application Program), and the own codes, UPMORO (code to study orography effects) and UPMPARK (code to study wake effects in wind parks). Different kinds of data have been collected about climate, topography, roughness of the land, environmentally protected areas, town and village distribution, population density, main facilities and electric power supply. The Spanish National Meteorological Institute has nine wind measurement stations in the region, but only four of them have good and reliable temporary wind data, with time measurement periods that are long enough to provide representative correlations among stations. The Observed Wind Climates of the valid meteorological stations have been made. The Wind Atlas and the resource grid have been calculated, especially in the high wind resource areas, selecting appropriate measurements stations and using criteria based on proximity, similarity and ruggedness index. Some areas cannot be used as a wind energy resource mainly because they have environmental regulation or, in some cases, are very close

    2013-06-15

    The Remote Sensing in Wind Energy report provides a description of several topics and it is our hope that students and others interested will learn from it. The idea behind it began in year 2008 at DTU Wind Energy (formerly Risoe) during the first PhD Summer School: Remote Sensing in Wind Energy. Thus it is closely linked to the PhD Summer Schools where state-of-the-art is presented during the lecture sessions. The advantage of the report is to supplement with in-depth, article style information. Thus we strive to provide link from the lectures, field demonstrations, and hands-on exercises to theory. The report will allow alumni to trace back details after the course and benefit from the collection of information. This is the third edition of the report (first externally available), after very successful and demanded first two, and we warmly acknowledge all the contributing authors for their work in the writing of the chapters, and we also acknowledge all our colleagues in the Meteorology and Test and Measurements Sections from DTU Wind Energy in the PhD Summer Schools. We hope to continue adding more topics in future editions and to update and improve as necessary, to provide a truly state-of-the-art 'guideline' available for people involved in Remote Sensing in Wind Energy.

  18. Prospects for a wind pump industry in Sri Lanka

    International Nuclear Information System (INIS)

    Fernando, S.

    1991-01-01

    Since 1977 considerable effort has been made in Sri Lanka to develop and disseminate wind pumping systems primarily in the small-scale agricultural sector in the island's dry zone. Through close cooperation with the Consultancy Services Wind Energy Developing Countries (CWD) in the Netherlands this programme has been successful in developing the necessary hardware but the broad objective of promoting wide spread use of wind pumping in Sri Lanka is yet to materialize. In analyzing probable reasons for this, the paper highlights that the basic arguments underlying the origin of the project in 1976, such as foreign exchange savings and local industrial development, became irrelevant to the post 1977 political and economic policies of the new government. Thus, the general economic framework adopted in Sri Lanka since 1977 does not seem to provide the necessary pre-conditions for development of a local industry for wind pumps. Due to this reason and the fact that kerosene oil used in conventional agriculturla pumps is subsidized, the ability of wind pumps to compete in the wind pump market seems highly constrained. It is concluded that under such conditions the prospects for the manufacturing and marketing of wind pumps on an industrial scale are not very favourable

    2017-12-01

    Full Text Available The development of the wind energy industry is seriously restricted by grid connection issues and wind energy generation rejections introduced by the intermittent nature of wind energy sources. As a solution of these problems, a wind power system integrating with a thermal energy storage (TES system for district heating (DH is designed to make best use of the wind power in the present work. The operation and control of the system are described in detail. A one-dimensional system model of the system is developed based on a generic model library using the object-oriented language Modelica for system modeling. Validations of the main components of the TES module are conducted against experimental results and indicate that the models can be used to simulate the operation of the system. The daily performance of the integrated system is analyzed based on a seven-day operation. And the influences of system configurations on the performance of the integrated system are analyzed. The numerical results show that the integrated system can effectively improve the utilization of total wind energy under great wind power rejection.

  1. Improving weather forecasts for wind energy applications

    Weather forecasts play an important role in the energy industry particularly because of the impact of temperature on electrical demand. Power system operation requires that this variable and somewhat unpredictable demand be precisely met at all times and locations from available generation. As wind generation makes up a growing component of electricity supply around the world, it has become increasingly important to be able to provide useful forecasting for this highly variable and uncertain energy resource. Of particular interest are forecasts of weather events that rapidly change wind energy production from one or more wind farms. In this paper we describe work underway to improve the wind forecasts currently available from standard Numerical Weather Prediction (NWP) through a bias correction methodology. Our study has used the Australian Bureau of Meteorology MesoLAPS 5 km limited domain model over the Victoria/Tasmania region, providing forecasts for the Woolnorth wind farm, situated in Tasmania, Australia. The accuracy of these forecasts has been investigated, concentrating on the key wind speed ranges 5 - 15 ms-1 and around 25 ms-1. A bias correction methodology was applied to the NWP hourly forecasts to help account for systematic issues such as the NWP grid point not being at the exact location of the wind farm. An additional correction was applied for timing issues by using meteorological data from the wind farm. Results to date show a reduction in spread of forecast error for hour ahead forecasts by as much as half using this double correction methodology - a combination of both bias correction and timing correction.

    Maguire, Karen Kay

    2011-12-01

    My dissertation focuses on the influence of politics, policies, and markets in determining oil and natural gas and wind energy development. In the first chapter, I examine the role of federal elected political influence and market factors in determining the acres of oil and natural gas leases issued on Bureau of Management (BLM) lands in the western United States between 1978 and 2008. I seek to determine if the political party and ideology of the federal political environment influence the number of acres that are leased and if there is disparate federal political influence in states that have a large amount of federal lands. Using a random effects Tobit model for a 17-state sample of the westernmost states in the contiguous United States, I find that more conservative federal political influence leads to additional leasing. The results are consistent across Senate committee leaders, Senate majority leadership, and the President's office. The further found that the influence of politics on leasing is not stronger in states with more federal lands. In the second chapter, I analyze the influence of state and federal political party changes and market factors on state oil and natural gas permitting. My findings, using a first-differenced empirical model for two samples, a 19-state sample, from 1990--2007, and a 14-state sample, from 1977--2007, indicate that the influence of state political party changes are trumped by economic factors. Oil and gas prices are the main drivers of permitting changes, while the state political party changes for the state legislatures and Governor's office are consistently not significant. In the third chapter I focus on the role of electricity markets and renewable energy regulation in wind development across the United States. My findings, using a random effects Tobit model with a 25-state sample, from 1994--2008, indicate that the implementation of state Renewables Portfolio Standards (RPS), the Federal Production Tax Credit (PTC

    2015-11-01

    This guide addresses the different aspects of wind-based power generation. It outlines the role of wind energy to meet objectives related to the share of renewable energies in the French energy mix, that wind energy is actually replacing fossil energies, that it is based on local resources within higher safety and less wastage, that current advances are made to integrate wind energy production into the grid, and that it is a solution to diversify energy production. Some figures are presented and commented, regarding onshore wind energy production in France, the location of wind farms, and wind energy production in comparison with other renewable sources. The operation of a wind turbine is described and the different types of wind turbines are evoked. The issue of wind farm planning with citizen participation is addressed: regional planning, studies of pre-feasibility for location selection, procedure, and content of the impact study (radars, fauna and flora, landscapes, safety, health). Other features are outlined: a planned dismantling, and a globally favourable perception. The next part addresses offshore wind energy: the interesting potential of stronger and more reliable wind at sea (European situation, French opportunities, elements comprised in an offshore wind farm), impacts (on marine ecosystems, on neighbouring localities, and interests for visitors). Economic aspects are then addressed: cost and profitability, economic spin-offs, and perspectives. The last part concerns individuals and the possibilities to participate to wind farm projects or to invest in small wind turbines with some prerequisites (constant and steady winds, installation assessment, required expertise, indispensable preliminary steps, costs, aids and profitability)

    This article presents the outcomes of a recent study carried out among wind energy manufacturers and developers regarding the current generation costs of wind energy projects in Europe, the factors that most influence them, as well as the reasons behind their recent increase and their expected future evolution. The research finds that the generation costs of an onshore wind farm are between 4.5 and 8.7 EURcent/kWh; 6-11.1 EURcent/kWh when located offshore, with the number of full hours and the level of capital cost being the most influencing elements. Generation costs have increased by more than 20% over the last 3 years mainly due to a rise of the price of certain strategic raw materials at a time when the global demand has boomed. However, the competitive position of wind energy investments vis-a-vis other technologies has not been altered. In the long-term, one would expect production costs go down; whether this will be enough to offset the higher price of inputs will largely depend on the application of correct policies, like R and D in new materials, O and M with remote-control devices, offshore wind turbines and substructures; introduction of advanced siting and forecasting techniques; access to adequate funding; and long-term legal stability.

  1. IEA Wind Task 26: The Past and Future Cost of Wind Energy, Work Package 2

    Energy Technology Data Exchange (ETDEWEB)

    Lantz, E.; Wiser, R.; Hand, M.

    2012-05-01

    Over the past 30 years, wind power has become a mainstream source of electricity generation around the world. However, the future of wind power will depend a great deal on the ability of the industry to continue to achieve cost of energy reductions. In this summary report, developed as part of the International Energy Agency Wind Implementing Agreement Task 26, titled 'The Cost of Wind Energy,' we provide a review of historical costs, evaluate near-term market trends, review the methods used to estimate long-term cost trajectories, and summarize the range of costs projected for onshore wind energy across an array of forward-looking studies and scenarios. We also highlight the influence of high-level market variables on both past and future wind energy costs.

  2. Offshore wind energy, who will risk investment?

    International Nuclear Information System (INIS)

    Dupin, Ludovic; Moragues, Manuel

    2013-01-01

    As Europe plans to install 40 GW of offshore wind energy production by 2020 and only 5 GW are already installed, investment is a crucial issue for a still immature industry and in a context where risk management is critical, notably during construction (harsh working conditions, costs of construction, of maintenance and costs related to delays). Other aspects are also related to financial risks like, for example, the cost of offshore wind farm connection to the grid (this has been an underestimated issue in Germany). Then operation and exploitation have to face climate events although, according to relatively recent exploitation data, availability is quite good. The durability of political support is not so sure in a context of political and regulatory instability and of economic crisis. In France, after the first bidding, the wind energy industrial sector is emerging and many small and medium companies enter this activity in the trail of Areva and Alstom, with thousands of job creations and export perspectives. Some offshore wind turbines are briefly presented (by Alstom, Areva, RE Power, Siemens and Vestas)

  4. Constructing China’s wind energy innovation system

    International Nuclear Information System (INIS)

    Klagge, Britta; Liu Zhigao; Campos Silva, Pedro

    2012-01-01

    The rapid rise of China as the largest wind energy market worldwide with several global leaders in turbine manufacturing received much attention from both scholarly and policy-analytical work. However, little attention has been given to the innovation activities of the Chinese wind industry. In our paper, we aim to address this gap, based on second-hand sources and over 50 personal interviews with wind energy-related experts. We argue that China’s wind industry has made great progress in terms of manufacturing and installing, but is confronted with various challenges and problems regarding the development of its indigenous innovation capabilities. Using innovation systems approaches as an analytical tool and focusing on institutions, actors, technology and their interaction in supporting innovation activities, we decompose the elements of China’s wind energy innovation system and their role in developing the domestic wind industry. Against this backdrop we identify and discuss challenges and obstacles in the development of an innovation-driven wind industry in China. The paper strongly argues that more attention should be paid to improve the coordination and cooperation among the various actors of the wind energy innovation system, to the build-up of a market-oriented education and training system as well as to intellectual property protection. - Highlights: ► Innovation systems concepts as analytical tool to understand wind energy in China. ► Focus on institutions, actor constellations and technology development in China. ► Analysis of success in manufacturing and the rapid rise of China’s wind industry. ► Identification of challenges and problems regarding innovation activities. ► Recommendation to (better) integrate innovation policy and wind industry policy.

  5. Industrial wind turbines and adverse health effects.

    Science.gov (United States)

    Jeffery, Roy D; Krogh, Carmen M E; Horner, Brett

    2014-01-01

    Some people living in the environs of industrial wind turbines (IWTs) report experiencing adverse health and socioeconomic effects. This review considers the hypothesis that annoyance from audible IWTs is the cause of these adverse health effects. We searched PubMed and Google Scholar for articles published since 2000 that included the terms "wind turbine health," "wind turbine infrasound," "wind turbine annoyance," "noise annoyance" or "low frequency noise" in the title or abstract. Industrial wind turbines produce sound that is perceived to be more annoying than other sources of sound. Reported effects from exposure to IWTs are consistent with well-known stress effects from persistent unwanted sound. If placed too close to residents, IWTs can negatively affect the physical, mental and social well-being of people. There is sufficient evidence to support the conclusion that noise from audible IWTs is a potential cause of health effects. Inaudible low-frequency noise and infrasound from IWTs cannot be ruled out as plausible causes of health effects.

  6. Circular economy opportunity in the wind industry. Final report

    2015-05-01

    The objective of this study is to identify how the circular economy can be an opportunity for the French wind industry. A broad review of circular economy issues for the wind industry value chain has been conducted in order to be used as a decision making tool for ADEME and the wind industry stakeholders. First of all, a 'flow analysis' (including material, logistic and services related to wind power) has been carried out in order to highlight the specific challenges of circular economy for the wind sector. The strategic opportunities that meet these issues have then been identified. A selection of six opportunities has been further investigated to assess the benefits, to analyze the barriers and to identify actions that ADEME could initiate to foster these opportunities. These investigated opportunities are the following: - To structure a recycling chain for wind blades; - To promote the business model of the extension of wind turbine's lifetime; - To promote skills improvement of local providers for reconditioning and maintenance services; - To adapt the offshore hubs to integrate dismantling activity of onshore equipments; - To increase the manufacturing capacity of wind towers in France to increase local sourcing; - To encourage the creation of a leading French manufacturer to optimize the supply chain. In the light of this analysis, it can be concluded that circular economy represents a strategic opportunity for the French wind energy sector. The opportunities we focused on make up a consistent set of initiatives that improve the environmental, economic and social performance of the wind energy sector by strengthening industrial activities and services throughout all the life cycle: manufacturing stage (optimization of logistics flows and local manufacturing), use phase (maintenance, repair) and end-of-life phase of wind turbine (dismantling, recycling). While the sector has so far been focused on better solving technological challenges and

    1997-07-01

    The report describes the business plan for the establishment of a Wind Energy Centre in Gujarat. This Wind Energy Center has to provide a reliable delivery of a range of development and technical quality assurance services to the wind energy industry in northern India on the basis of sustained operations and recovery of all operating costs and - contingent on the way the Centre is financed - at least part of the initial investment costs. Core activities of the Wind Energy Centre are: Research and development supporting activities for the wind energy sector; Testing and certification of wind energy equipment; Consultancy, monitoring and information services; and Training courses on wind energy technology and implementation. The wind energy centre aims with its services at a number of customers: the manufacturing industry, wind farm developers and governmental authorities. An exploration of the market for the services of the envisaged wind energy centre shows that the concept is financially viable. A set of assumptions has been made about the growth rate of the installed wind power capacity in Northern India and about the number of wind turbine manufacturing companies in the target area of the centre. From these assumptions the total number of new wind turbine types coming on the Indian market annually is derived for a period of ten years. These figures have served as a basis for the determination of the required manpower and facilities of the centre for design and development support activities, feasibility and siting studies, testing and certification. Furthermore a projection has been made for providing expert manpower capacity for carrying out R and D, consultancy and other services. 14 tabs., 1 ref

    Thabit, S. S.; Stark, J.

    This paper investigates the impact of the provisions of the new Energy Act, 1983 on industrial wind-powered private generators of electricity and the effects of published tariffs on various industrial working patterns. Up to 30 percent savings can be achieved in annual electricity bill costs for an industrial generator/user of electricity working a single daily shift, if located in a favorable, 7 m/s mean annual wind speed regime. Variation of the availability charge between Electricity Boards about a base value of 0.70 pounds sterling/kVA was found to have insignificant (+ or - 1.3 percent) impact on total electricity bill costs. It was also shown that for industrial users of electricity, the simpler two-rate purchase terms were commercially adequate when compared with the four-rate alternative where expensive metering becomes necessary.

    Wind power is an inexhaustible form of energy that is being captured throughout the U.S. to power the engine of our economy. A robust, domestic wind industry promises to increase U.S. industry growth and competitiveness, strengthen U.S. energy security independence, and promote domestic manufacturing nationwide. As of 2016, ~82GW of wind capacity had been installed, and wind power now provides more than 5.5% of the nation’s electricity and supports more than 100,000 domestic jobs, including 500 manufacturing facilities in 43 States. To reach the U.S. Department of Energy’s (DOE’s) 2015 Wind Vision study scenario of wind power serving 35% of the nation's end-use demand by 2050, significant advances are necessary in all areas of wind technologies and market. An area that can greatly impact the cost and rate of innovation in wind technologies is the use of advanced manufacturing, with one of the most promising areas being additive manufacturing (AM). Considering the tremendous promise offered by advanced manufacturing, it is the purpose of this report to identify the use of AM in the production and operation of wind energy systems. The report has been produced as a collaborative effort for the DOE Wind Energy Technology Office (WETO), between Oak Ridge National Laboratory (ORNL) and the National Renewable Energy Laboratory (NREL).

  19. The destiny of wind energy manufacturers

    International Nuclear Information System (INIS)

    Weller, Th.

    1996-01-01

    Today's market of wind energy manufacturers and its future development is analysed by use of a trend based scenario method, taking into account all future dynamics of the industry. The status quo of the industry is found to be fundamentally unstable and has already started to change its structure. Dependent on social acceptance of renewables and political behaviour (''conventional'' versus ''innovative'') four different extreme markets are described into which the development may go. Conclusions are drawn how to increase the probability of positive wind energy scenarios. Manufacturers of wind energy systems are categorised into four different groups: stars, problem children, dogs and cash cows. Each group is analysed based on its present market position, its innovative power and its capability to adapt to the requirements of the four considered ''futures''. The summary is that - wherever future developments will go - most of today's manufacturers will cease to exist in their present form, will leave the market, be merged into larger units or migrate to service providers.

  5. Measuring industrial energy savings

    International Nuclear Information System (INIS)

    Kelly Kissock, J.; Eger, Carl

    2008-01-01

    Accurate measurement of energy savings from industrial energy efficiency projects can reduce uncertainty about the efficacy of the projects, guide the selection of future projects, improve future estimates of expected savings, promote financing of energy efficiency projects through shared-savings agreements, and improve utilization of capital resources. Many efforts to measure industrial energy savings, or simply track progress toward efficiency goals, have had difficulty incorporating changing weather and production, which are frequently major drivers of plant energy use. This paper presents a general method for measuring plant-wide industrial energy savings that takes into account changing weather and production between the pre and post-retrofit periods. In addition, the method can disaggregate savings into components, which provides additional resolution for understanding the effectiveness of individual projects when several projects are implemented together. The method uses multivariable piece-wise regression models to characterize baseline energy use, and disaggregates savings by taking the total derivative of the energy use equation. Although the method incorporates search techniques, multi-variable least-squares regression and calculus, it is easily implemented using data analysis software, and can use readily available temperature, production and utility billing data. This is important, since more complicated methods may be too complex for widespread use. The method is demonstrated using case studies of actual energy assessments. The case studies demonstrate the importance of adjusting for weather and production between the pre- and post-retrofit periods, how plant-wide savings can be disaggregated to evaluate the effectiveness of individual retrofits, how the method can identify the time-dependence of savings, and limitations of engineering models when used to estimate future savings

  8. Toward Robust and Efficient Climate Downscaling for Wind Energy

    Science.gov (United States)

    Vanvyve, E.; Rife, D.; Pinto, J. O.; Monaghan, A. J.; Davis, C. A.

    2011-12-01

    This presentation describes a more accurate and economical (less time, money and effort) wind resource assessment technique for the renewable energy industry, that incorporates innovative statistical techniques and new global mesoscale reanalyzes. The technique judiciously selects a collection of "case days" that accurately represent the full range of wind conditions observed at a given site over a 10-year period, in order to estimate the long-term energy yield. We will demonstrate that this new technique provides a very accurate and statistically reliable estimate of the 10-year record of the wind resource by intelligently choosing a sample of ±120 case days. This means that the expense of downscaling to quantify the wind resource at a prospective wind farm can be cut by two thirds from the current industry practice of downscaling a randomly chosen 365-day sample to represent winds over a "typical" year. This new estimate of the long-term energy yield at a prospective wind farm also has far less statistical uncertainty than the current industry standard approach. This key finding has the potential to reduce significantly market barriers to both onshore and offshore wind farm development, since insurers and financiers charge prohibitive premiums on investments that are deemed to be high risk. Lower uncertainty directly translates to lower perceived risk, and therefore far more attractive financing terms could be offered to wind farm developers who employ this new technique.

    Under its wind energy research and development program, the U.S. Department of Energy (DOE) works as a partner with industry to improve understanding of wind system technology and to develop and deploy advanced wind turbines in multi-regional markets. Installed capacity in the U.S. reached 1770 MW by the end of 1995. However, this figure does not include some capacity that was retired or brought off line. Growth of about 140 MW during 1995, is attributed to improved and lower cost turbines and was stimulated in part by the availability of energy tax credits and production and financial incentives. In addition, there are nearly 500 MW of firm contracts for new domestic wind plants. Recently, there has been substantial growth in both Europe and the rest of the world, those countries other than Europe and the U.S. The U.S. DOE Wind Energy Systems Program is continuing broad based research and technology development focusing on advanced wind turbine development. Contracts have been placed with industry for next generation design studies, innovative subsystems applied research, and value engineering to improve existing turbines. Some of these turbines are now being deployed in utility verification projects. Over the past year, the U.S. opened its National Wind Technology Center, located near Golden, Colorado. The center will include a new user facility to serve as a wind turbine blade and system testing and research center for industry. (author)

  14. The resilience of Australian wind energy to climate change

    2018-02-01

    The Paris Agreement limits global average temperature rise to 2 °C and commits to pursuing efforts in limiting warming to 1.5 °C above pre-industrial levels. This will require rapid reductions in the emissions of greenhouse gases and the eventual decarbonisation of the global economy. Wind energy is an established technology to help achieve emissions reductions, with a cumulative global installed capacity of ~486 GW (2016). Focusing on Australia, we assess the future economic viability of wind energy using a 12-member ensemble of high-resolution regional climate simulations forced by Coupled Model Intercomparison Project (CMIP) output. We examine both near future (around 2030) and far future (around 2070) changes. Extractable wind power changes vary across the continent, though the most spatially coherent change is a small but significant decrease across southern regions. The cost of future wind energy generation, measured via the Levelised Cost of Energy (LCOE), increases negligibly in the future in regions with significant existing installed capacity. Technological developments in wind energy generation more than compensate for projected small reductions in wind, decreasing the LCOE by around 30%. These developments ensure viability for existing wind farms, and enhance the economic viability of proposed wind farms in Western Australian and Tasmania. Wind energy is therefore a resilient source of electricity over most of Australia and technological innovation entering the market will open new regions for energy production in the future.

    Wind power is today a mature technology, which at windy locations, is economically competitive to conventional power generation technologies. This and growing global environmental concerns have led governments to encourage and plan for wind energy development, a typical aim being 10% of electricity...... consumption. The successful operation of the three major power systems of Cape Verde, with a total wind energy penetration of about 15% since December 1994, demonstrates that power systems can be operated with high penetration of wind energy by adding simple control and monitoring systems only. Thorough...... analyses conclude that expanding to even above 15% wind energy penetration in the Cape Verde power systems is economical. Worldwide, numerous locations with favorable wind conditions and power systems similar to the Capeverdean provide good opportunities for installing wind farms and achieving high wind...

    In the context of the wind power use increase in the european union, the average wind turbines power increases also. These turbines are more adapted to little wind conditions. The offshore wind power is certainly the more adapted to the problem of implementation sites, meanwhile the offshore project costs are more expensive. More competitive costs are a challenge for the offshore wind channel.

    At the 1995 meeting of the International Energy Agency CADDET renewable energy technologies programme, contributors aimed to advise on wind energy use and identify future needs for analysis of future trends and review research tasks. Three major trends leading to the commercial exploitation of wind energy are identified. Firstly, cost reduction and increased efficiency is aimed at through technical innovation, economies of scale and reduced labour costs. The environmental and social benefits of wind energy are acknowledged in the second place. Lastly, wind turbine deployment has been given decisive market incentives. Two major barriers block the development of the wind energy market, availability of site locations and the current economic state of countries likely to espouse wind energy. (UK)

  8. Wind energy applications of synthetic aperture radar

    2006-11-15

    Synthetic aperture radars (SAR), mounted on satellites or aircraft, have proven useful for ocean wind mapping. Wind speeds at the height 10 m may be retrieved from measurements of radar backscatter using empirical model functions. The resulting wind fields are valuable in offshore wind energy planning as a supplement to on site measurements, which are costly and sparse, and model wind fields, which are not fully validated. Two applications of SAR measurements in offshore wind energy planning are addressed here: the study of wind farm wake effects and the potential of using SAR winds in offshore wind resource assessment. Firstly, wind wakes behind two large offshore wind farms in Denmark Horns Rev and Nysted are identified. A region of reduced wind speed is found downstream of both wind farms from the SAR wind fields. The wake extent and magnitude depends on the wind speed, the atmospheric stability, and the fraction of turbines operating. Wind farm wake effects are detected up to 20 km downwind of the last turbine. This distance is longer than predicted by state-of-the art wake models. Wake losses are typically 10-20% near the wind farms. Secondly, the potential of using SAR wind maps in offshore wind resource assessment is investigated. The resource assessment is made through Weibull fitting to frequency observations of wind speed and requires at least 100 satellite observations per year for a given site of interest. Predictions of the energy density are very sensitive to the wind speed and the highest possible accuracy on SAR wind retrievals is therefore sought. A 1.1 m s{sup -1} deviation on the mean wind speed is found through comparison with mast measurements at Horns Rev. The accuracy on mean wind speeds and energy densities found from satellite measurements varies with different empirical model functions. Additional uncertainties are introduced by the infrequent satellite sampling at fixed times of the day. The accuracy on satellite based wind resource

    As a new and developing green energy business in emerging economies such as China, the wind power industry chain faces some complex issues that are further compounded by turbulent internal and external environments. To deal with the complex environment, the wind power industry needs to improve its level of flexibility so that it can become more adaptable to the changing environment. Hence it is important to explore the dynamics of the wind power industry chain flexibility with respect to the ever changing environment. This study uses questionnaire surveys and expert interviews to identify the influential flexibility components of the wind power industry chain. Subsequently a fuzzy cognitive mapping (FCM) methodology was used to establish a flexibility operating mechanism model. The research found that special attention should be paid to competition flexibility, technology flexibility, and intellectual property and talent flexibility. Policies play a pivotal role in regulating the driving effects of these components of flexibility with the aim being long term sustainability of a healthy level of overall flexibility of the wind power industry chain. This should in turn facilitate the sustainable development of the industry. - Highlights: • Wind power industry shall improve flexibility to deal with complex environment. • Critical components of flexibility of wind power industry chain were identified. • An operating mechanism model for flexibility of wind power industry is proposed. • Fuzzy cognitive mapping method is employed to model the dynamics of flexibility. • Policies play a pivotal role in fostering an industry environment toward flexibility

    This wind energy resource atlas identifies the wind characteristics and distribution of the wind resource in two regions of southeast China. The first region is the coastal area stretching from northern Fujian south to eastern Guangdong and extending approximately 100 km inland. The second region is centered on the Poyang Lake area in northern Jiangxi. This region also includes parts of two other provinces-Anhui and Hubei-and extends from near Anqing in Anhui south to near Nanchang in Jiangxi. The detailed wind resource maps and other information contained in the atlas facilitate the identification of prospective areas for use of wind energy technologies, both for utility-scale power generation and off-grid wind energy applications. We created the high-resolution (1-km2) maps in 1998 using a computerized wind resource mapping system developed at the National Renewable Energy Laboratory (NREL). The mapping system uses software known as a Geographical Information System (GIS).

    The IEA Policy Pathway publications provide details on how to implement specific recommendations drawn from the IEA 25 Energy Efficiency Policy Recommendations. This Policy Pathway, jointly produced by the International Energy Agency and the Institute for Industrial Productivity, develops the critical steps for policy makers implementing energy management programmes for industry. Optimising energy use in industry is essential to improve industrial competitiveness and achieve wider societal goals such as energy security, economic recovery and development, climate change mitigation and environmental protection. While there is significant potential to decrease energy consumption in this sector, opportunities to improve energy efficiency are still under-exploited. Energy management programmes have shown to be instrumental in addressing many of the barriers that inhibit wide-scale uptake of energy management in industry. The Policy Pathway builds on lessons learned from country experiences and provides actionable guidance on how to plan and design, implement, evaluate and monitor energy management programmes for industry.

  14. Does wind energy mitigate market power in deregulated electricity markets?

    International Nuclear Information System (INIS)

    Ben-Moshe, Ori; Rubin, Ofir D.

    2015-01-01

    A rich body of literature suggests that there is an inverse relationship between wind power penetration rate into the electricity market and electricity prices, but it is unclear whether these observations can be generalized. Therefore, in this paper we seek to analytically characterize market conditions that give rise to this inverse relationship. For this purpose, we expand a recently developed theoretical framework to facilitate flexibility in modeling the structure of the electric industry with respect to the degree of market concentration and diversification in the ownership of wind power capacity. The analytical results and their attendant numerical illustrations indicate that the introduction of wind energy into the market does not always depress electricity prices. Such a drop in electricity prices is likely to occur when the number of firms is large enough or the ownership of wind energy is sufficiently diversified, or most often a combination of the two. Importantly, our study defines the circumstances in which the question of which type of firm invests in wind power capacity is crucial for market prices. - Highlights: • Studies show that electricity prices decrease with increased wind power capacity. • We investigate market conditions that give rise to this inverse relationship. • Average prices for wind energy are systematically lower than average market prices. • Conventional generation firms may increase market power by investing in wind farms. • Energy policy should seek to diversify the ownership of wind power capacity

  18. Estimation of wind characteristics at potential wind energy conversion sites

    Energy Technology Data Exchange (ETDEWEB)

    1979-10-01

    A practical method has been developed and applied to the problem of determining wind characteristics at candidate wind energy conversion sites where there are no available historical data. The method uses a mass consistent wind flow model (called COMPLEX) to interpolate between stations where wind data are available. The COMPLEX model incorporates the effects of terrain features and airflow. The key to the practical application of COMPLEX to the derivation of wind statistics is the model's linearity. This allows the input data sets to be resolved into orthogonal components along the set of eigenvectors of the covariance matrix. The solution for each eigenvector is determined with COMPLEX; the hourly interpolated winds are then formed from linear combinations of these solutions. The procedure requires: acquisition and merger of wind data from three to five stations, application of COMPLEX to each of the seven to 11 (depending on the number of stations for which wind data are available) eigenvectors, reconstruction of the hourly interpolated winds at the site from the eigenvector solutions, and finally, estimating the wind characteristics from the simulated hourly values. The report describes the methodology and the underlying theory. Possible improvements to the procedure are also discussed.

    Because wind data are available only at scattered locations, a quantitative method is needed to estimate the wind resource at specific sites where wind energy generation may be economically feasible. This report describes a computer model that makes such estimates. The model uses standard weather reports and terrain heights in deriving wind estimates; the method of computation has been changed from what has been used previously. The performance of the current model is compared with that of the earlier version at three sites; estimates of wind energy at four new sites are also presented.

  1. The Wind Energy Potential of Iceland

    While Iceland has an abundant wind energy resource, its use for electrical power production has so far been limited. Electricity in Iceland is generated primarily from hydro- and geothermal sources, and adding wind energy has so far not been considered practical or even necessary. However, wind energy is becoming a more viable option, as opportunities for new hydro- or geothermal power installations become limited. In order to obtain an estimate of the wind energy potential of Iceland, a wind atlas has been developed as part of the joint Nordic project 'Improved Forecast of Wind, Waves and Icing' (IceWind). Downscaling simulations performed with the Weather Research and Forecasting (WRF) model were used to determine the large-scale wind energy potential of Iceland. Local wind speed distributions are represented by Weibull statistics. The shape parameter across Iceland varies between 1.2 and 3.6, with the lowest values indicative of near-exponential distributions at sheltered locations, and the highest values indicative of normal distributions at exposed locations in winter. Compared with summer, average power density in winter is increased throughout Iceland by a factor of 2.0 - 5.5. In any season, there are also considerable spatial differences in average wind power density. Relative to the average value within 10 km of the coast, power density across Iceland varies between 50 - 250%, excluding glaciers, or between 300 - 1500 W m-2 at 50 m above ground level in winter. At intermediate elevations of 500 - 1000 m above mean sea level, power density is independent of the distance to the coast. In addition to seasonal and spatial variability, differences in average wind speed and power density also exist for different wind directions. Along the coast in winter, power density of onshore winds is higher by 100 - 700 W m-2 than that of offshore winds. The regions with the highest average wind speeds are impractical for wind farms, due to the distances from road

    Research highlights: → Life cycle analysis reveals the viability of moderate wind fields utilization. → Wind turbine is the greenest electricity generator at a touristic site. → Wind parks should be collective applications of small hotel-apartments owners. -- Abstract: The feasibility of wind energy utilization at moderate wind fields was investigated for a typical touristic coastal site in Western Greece. Initially, the wind speed and direction as well as its availability, duration and diurnal variation were assessed. For an analysis period of eight years, the mean wind speed at ten meters was determined as 3.8 m s -1 with a small variation in monthly average wind speeds between 3.0 (January) and 4.4 m s -1 (October). The mean wind power density was less than 200 W m -2 at 10 m indicating the limiting suitability of the site for the usual renewable energy applications. However, life cycle analysis for wind turbine generators with lower cut-in, cut-out, and rated speeds revealed that the energy yield ratio can reach a value of six for a service life of 20 years while the energy pay-back period can be 3 years with 33 kt CO 2 -e of avoided greenhouse emissions. Therefore, the recent technological turbine improvements make wind power viable even at moderate wind fields. Moreover, the study of electricity supply of typical small hotel-apartments in the region of Western Greece indicated that the installation of 300 wind turbine generators in these moderate wind fields would cover the total consumption during the open touristic period with profits during the rest of the year. According to these results, wind turbine generators are the 'greenest' way of generating electricity in touristic coastal sites, even of moderate wind speeds.

    The main objective of the THERMIE Associated Measure WE05 is to study market conditions and estimate the market for wind power in Eastern Europe. This report describes the results of a study of the conditions in Poland, which has been concentrated on the following areas: wind energy potential in Poland; data concerning the present structure of the power production system including costs; payback prices, subsidies, etc. with relation to renewable energy sources, especially wind power; information on existing wine turbines and their production in Poland; possibilities for co-production of wind turbines by Polish and EC factories, and rules and legislation pertaining to the establishment of wind turbines and to power production by wind, eg regulations related to grid connection, safety and environment. According to existing data there are possibilities for using the wind potential in certain parts of poland. The wind data have to be improved if particular sites are considered for wind parks. The current official plans concerning the energy system have taken renewable sources into consideration, including wind power that is estimated to contribute ∼ 1 GWh by 2005-2010. Wind turbines may be connected to the public grid with due regard to the strength of the line. Presently, the owner has to pay all the costs, however, new rules are under consideration. The conditions for the connection and operation of wind turbines have to be discussed with the particular utility on an an-hoc basis. (EG)

    This article discussed the opportunities that wind energy technology can bring to developing countries in Africa. Solar, hydro and wind energy along with biofuels are among the renewable energy sources being used in Africa, although wind energy is not being used to its potential due to a lack of financial means; constraints in regulatory legislation; lack of structure; lack of knowledge concerning wind energy; and the lack of competent human resources for the installation and management of wind turbines. Technical barriers also exist, such as the lack of interconnection networks and the already existing facilities for power generation. According to a 2004 Canadian study, the greatest potential for wind energy development lies in the northern part of Africa followed by regions in the east, west and south of the continent. Morocco and Tunisia have established regulations regarding wind energy development. Countries such as Algeria and Egypt, which have abundant fossil fuel, would turn to wind energy from an environmental standpoint. The countries of Djibouti, Lesotho, Tchad, Seychelles, Mauritius rely on other forms of renewable energy, including hydro, geothermal, photovoltaic and biofuels. It was concluded that the future of wind energy relies on regional cooperation, technology transfer and subsidies from industrialized nations. 1 fig.

    The National Offshore Wind Energy Grid Interconnection Study (NOWEGIS) considers the availability and potential impacts of interconnecting large amounts of offshore wind energy into the transmission system of the lower 48 contiguous United States. A total of 54GW of offshore wind was assumed to be the target for the analyses conducted. A variety of issues are considered including: the anticipated staging of offshore wind; the offshore wind resource availability; offshore wind energy power production profiles; offshore wind variability; present and potential technologies for collection and delivery of offshore wind energy to the onshore grid; potential impacts to existing utility systems most likely to receive large amounts of offshore wind; and regulatory influences on offshore wind development. The technologies considered the reliability of various high-voltage ac (HVAC) and high-voltage dc (HVDC) technology options and configurations. The utility system impacts of GW-scale integration of offshore wind are considered from an operational steady-state perspective and from a regional and national production cost perspective.

    results are often text-based demonstrations. WINS includes a powerful visualization tool and user interface capability for transmission analyses, planning, and assessment, which will be of great interest to power market participants, power system planners and operators, and state and federal regulatory entities; and (3) WINS can handle extended transmission models for wind integration studies. WINS models include limitations on transmission flow as well as bus voltage for analyzing power system states. The existing decision tools often consider transmission flow constraints (dc power flow) alone which could result in the over-utilization of existing resources when analyzing wind integration. WINS can be used to assist power market participants including transmission companies, independent system operators, power system operators in vertically integrated utilities, wind energy developers, and regulatory agencies to analyze economics, security, and reliability of various options for wind integration including transmission upgrades and the planning of new transmission facilities. WINS can also be used by industry for the offline training of reliability and operation personnel when analyzing wind integration uncertainties, identifying critical spots in power system operation, analyzing power system vulnerabilities, and providing credible decisions for examining operation and planning options for wind integration. Researches in this project on wind integration included (1) Development of WINS; (2) Transmission Congestion Analysis in the Eastern Interconnection; (3) Analysis of 2030 Large-Scale Wind Energy Integration in the Eastern Interconnection; (4) Large-scale Analysis of 2018 Wind Energy Integration in the Eastern U.S. Interconnection. The research resulted in 33 papers, 9 presentations, 9 PhD degrees, 4 MS degrees, and 7 awards. The education activities in this project on wind energy included (1) Wind Energy Training Facility Development; (2) Wind Energy Course

  14. Application and verification of ECMWF seasonal forecast for wind energy

    2015-04-01

    A good understanding of long-term annual energy production (AEP) is crucial when assessing the business case of investing in green energy like wind power. The art of wind-resource assessment has emerged into a scientific discipline on its own, which has advanced at high pace over the last decade. This has resulted in continuous improvement of the AEP accuracy and, therefore, increase in business case certainty. Harvesting the full potential output of a wind farm or a portfolio of wind farms depends heavily on optimizing operation and management strategy. The necessary information for short-term planning (up to 14 days) is provided by standard weather and power forecasting services, and the long-term plans are based on climatology. However, the wind-power industry is lacking quality information on intermediate scales of the expected variability in seasonal and intra-annual variations and their geographical distribution. The seasonal power forecast presented here is designed to bridge this gap. The seasonal power production forecast is based on the ECMWF seasonal weather forecast and the Vestas' high-resolution, mesoscale weather library. The seasonal weather forecast is enriched through a layer of statistical post-processing added to relate large-scale wind speed anomalies to mesoscale climatology. The resulting predicted energy production anomalies, thus, include mesoscale effects not captured by the global forecasting systems. The turbine power output is non-linearly related to the wind speed, which has important implications for the wind power forecast. In theory, the wind power is proportional to the cube of wind speed. However, due to the nature of turbine design, this exponent is close to 3 only at low wind speeds, becomes smaller as the wind speed increases, and above 11-13 m/s the power output remains constant, called the rated power. The non-linear relationship between wind speed and the power output generally increases sensitivity of the forecasted power

    Next to a study of the title subject attention is paid to the quantification of the wind energy potential and the conditions under which such potentials can be realized. The options are influenced by technical-economical, planning and socio-political factors, which are summarized in appendix 1 and discussed in chapter three. Results of interviews with experts in the field of wind energy can be found in appendix 2. Based on the impacts on the wind energy potential four wind energy development scenarios are compared in chapter four. The reference scenario is based on the present wind energy policy in the Netherlands. The other three scenarios are the Price-scenario (higher societal appreciation of electricity generated by wind power), the Site-scenario (matters of site selection and planning), and a Combined-scenario (combination of the Price- and the Site-scenario). For each scenario potential estimations were made for the years 2000, 2010, 2015, and restricted estimations for the year 2025. It is concluded that within 25 years 2,500 MW wind power can be realized on land and 6,000 MW on water. The main problems for the location on land and inland waterways are the planning restrictions, and for sea locations the limiting factor is the high cost price. Recommendations to the Dutch government to realize the potentials concern the facts that social advantages of wind energy should be part of the price of the energy, more sites should be made available for the application of wind energy, more research has to be carried out on the possibility of locating wind power generating systems at sea, and the social basis for wind energy should be maintained and even increased. 18 figs., 5 app., 47 refs

    Measurements with a combined cup anemometer/wind vane instrument, developed at the Department of Meteorology in Uppsala, is presented. The instrument has a frequency response of about 1 Hz, making it suitable not only for mean wind measurements, but also for studies of atmospheric turbulence. It is robust enough to be used for climatological purposes. Comparisons with data from a hot-film anemometer show good agreement, both as regards standard deviations and the spectral decomposition of the turbulent wind signal. The cup anemometer/wind vane instrument is currently used at three sites within the Swedish wind energy research programme. These measurements are shortly described, and a few examples of the results are given. 1 ref, 10 figs

    The results of simulation of the influence of energy storage on wind power quality are presented. Simulations are done using a mathematical model of energy storage. Results show the relation between storage power and energy, and the obtained increase in minimum available power from the combination...... of wind and storage. The introduction of storage enables smoothening of wind power on a timescale proportional to the storage energy. Storage does not provide availability of wind power at all times, but allows for a certain fraction of average power in a given timeframe to be available with high...... probability. The amount of storage capacity necessary for significant wind power quality improvement in a given period is found to be 20 to 40% of the energy produced in that period. The necessary power is found to be 80 to 100% of the average power of the period....

    Main electrical energy sources of Turkey are thermal and hydraulic. Most of the thermal sources are derived from natural gas. Turkey imports natural gas; therefore, decreasing usage of natural gas is very important for both economical and environmental aspects. Because of disadvantages of fossil fuels, renewable energy sources are getting importance for sustainable energy development and environmental protection. Among the renewable sources, Turkey has very high wind energy potential. The estimated wind power capacity of Turkey is about 83,000 MW while only 10,000 MW of it seems to be economically feasible to use. Start 2009, the total installed wind power capacity of Turkey was only 4.3% of its total economical wind power potential (433 MW). However, the strong development of wind energy in Turkey is expected to continue in the coming years. In this study, Turkey's installed electric power capacity, electric energy production is investigated and also Turkey current wind energy status is examined. (author)

  2. The Application of TAPM for Site Specific Wind Energy Forecasting

    2016-02-01

    Full Text Available The energy industry uses weather forecasts for determining future electricity demand variations due to the impact of weather, e.g., temperature and precipitation. However, as a greater component of electricity generation comes from intermittent renewable sources such as wind and solar, weather forecasting techniques need to now also focus on predicting renewable energy supply, which means adapting our prediction models to these site specific resources. This work assesses the performance of The Air Pollution Model (TAPM, and demonstrates that significant improvements can be made to only wind speed forecasts from a mesoscale Numerical Weather Prediction (NWP model. For this study, a wind farm site situated in North-west Tasmania, Australia was investigated. I present an analysis of the accuracy of hourly NWP and bias corrected wind speed forecasts over 12 months spanning 2005. This extensive time frame allows an in-depth analysis of various wind speed regimes of importance for wind-farm operation, as well as extreme weather risk scenarios. A further correction is made to the basic bias correction to improve the forecast accuracy further, that makes use of real-time wind-turbine data and a smoothing function to correct for timing-related issues. With full correction applied, a reduction in the error in the magnitude of the wind speed by as much as 50% for “hour ahead” forecasts specific to the wind-farm site has been obtained.

    With over 5, 660 MW installed in end-2010, France ranks fourth in Europe, behind Germany, Spain and Italy. The wind power industry currently employs almost 11, 000 people in France throughout the value chain. In 2009, the first edition of this directory listed over one hundred companies working in around twenty different areas. Encouraged by these initial positive results, and with the help of ADEME, the French syndicate for renewable energies (SER) asked Capgemini Consulting to undertake a study to identify and raise awareness among French industrials likely to enter into the wind energy market. The French Ministry for Ecology, Energy, Sustainable Development and the Sea, along with the Ministry for the Economy, Finance and Employment, were involved in the work. 400 companies were questioned as part of the study. Over 150 replies testified to the dynamic character of the wind power market in France and overseas, and the opportunities for diversification that it represents for traditional industries like metallurgy, aeronautics, defence and shipyards, etc. The study led to the creation of the initiative Windustry France, which currently groups over 300 companies either active in the French wind power market or set to enter it. Windustry France is a showcase of the industrial know-how that can be used in the wind power industry both onshore and offshore. It includes local set-ups developed around major fields of activity (e.g. car industry, aeronautics, mechanics, etc.) and industrial port zones (Dunkerque, Rouen/Le Havre, Brest, Nantes Saint-Nazaire, Bordeaux, etc.). Several ministries, regional stakeholders and authorities are also involved (local authorities, Regional directorates for industry, research and the environment (DReal) networks and chambers of commerce and industry), all of which contribute to making Windustry France a collective approach to industrial policy.

    2012-06-09

    In fiscal year 2005, the Energy & Environmental Research Center (EERC) received funding from the U.S. Department of Energy (DOE) to undertake a broad array of tasks to either directly or indirectly address the barriers that faced much of the Great Plains states and their efforts to produce and transmit wind energy at the time. This program, entitled Great Plains Wind Energy Transmission Development Project, was focused on the central goal of stimulating wind energy development through expansion of new transmission capacity or development of new wind energy capacity through alternative market development. The original task structure was as follows: Task 1 - Regional Renewable Credit Tracking System (later rescoped to Small Wind Turbine Training Center); Task 2 - Multistate Transmission Collaborative; Task 3 - Wind Energy Forecasting System; and Task 4 - Analysis of the Long-Term Role of Hydrogen in the Region. As carried out, Task 1 involved the creation of the Small Wind Turbine Training Center (SWTTC). The SWTTC, located Grand Forks, North Dakota, consists of a single wind turbine, the Endurance S-250, on a 105-foot tilt-up guyed tower. The S-250 is connected to the electrical grid on the 'load side' of the electric meter, and the power produced by the wind turbine is consumed locally on the property. Establishment of the SWTTC will allow EERC personnel to provide educational opportunities to a wide range of participants, including grade school through college-level students and the general public. In addition, the facility will allow the EERC to provide technical training workshops related to the installation, operation, and maintenance of small wind turbines. In addition, under Task 1, the EERC hosted two small wind turbine workshops on May 18, 2010, and March 8, 2011, at the EERC in Grand Forks, North Dakota. Task 2 involved the EERC cosponsoring and aiding in the planning of three transmission workshops in the midwest and western regions. Under Task

    This report quantifies Alaska's offshore wind resource capacity while focusing on its unique nature. It is a supplement to the existing U.S. Offshore Wind Resource Assessment, which evaluated the offshore wind resource for all other U.S. states. Together, these reports provide the foundation for the nation's offshore wind value proposition. Both studies were developed by the National Renewable Energy Laboratory. The analysis presented herein represents the first quantitative evidence of the offshore wind energy potential of Alaska. The technical offshore wind resource area in Alaska is larger than the technical offshore resource area of all other coastal U.S. states combined. Despite the abundant wind resource available, significant challenges inhibit large-scale offshore wind deployment in Alaska, such as the remoteness of the resource, its distance from load centers, and the wealth of land available for onshore wind development. Throughout this report, the energy landscape of Alaska is reviewed and a resource assessment analysis is performed in terms of gross and technical offshore capacity and energy potential.

  19. Wind's share in global energy markets

    International Nuclear Information System (INIS)

    Madsen, B.T.

    1997-01-01

    The question of how great of a contribution wind power can really make to the world's energy needs is discussed. Emphasis up until recently has been mainly on improving wind turbine technology and siting practices as it is these that will provide an answer. The International Energy Agency predicts that world energy demand will increase by 30-50% by 2010. More countries than ever are either using wind power now or are preparing for its use. Wind power continues to improve its price competitiveness. There is enough wind to cover our energy needs many times over, according to some reports twice the world's electricity supply could be met by utilizing just 5-10% of areas identified as having average wind speeds of 5 m/s or greater - ignoring population centers, forests and specially protected areas. But a major limiting factor to utilizing the available wind resource is the established grid systems, which can only base 20% of supply on wind power. It is concluded that wind can contribute significantly to the world's energy needs in the next century and beyond. If wind, which has taken giant leaps in improving its competitiveness over the past 20 hears, can be a major energy contributor by early next century, other renewables such as solar and biomass might also evolve to become major contributors too. If so, renewables, including hydro, could conceivably cover 50% of our energy needs by the middle of the next century. Much will depend on decision-makers at the centers of power. For Europe and certain other areas of the world, policies governing cross-border trade of electricity as well as the framework for environmental protection related to energy production will determine the final outcome

  20. Development of wind energy in Morocco

    2008-01-01

    Morocco's national energy policy includes the use of renewable energy sources to lessen its reliance on fossil fuels such as coal and oil. Legislation was recently passed to increase the threshold of electrical power from 10 MW to 50 MW. Solar and wind energy are the most abundant renewable energy resources in the country and are recommended for exploitation on a large scale. Feasibility studies conducted by the Centre de Developpement des Energies Renouvelables have shown that Morocco has enough wind energy to produce electricity on a large scale and interconnect it with the national power grid. Wind energy in the country could also be used for on-site power generation in remote villages or for desalination of seawater, particularly in the southern regions of Morocco which are most affected by drought. Essaouira, Tangier, Tetouan, Tarfaya, Dakhla, Laayoune and Taza were among the regions identified with significant wind resources. The total wind energy potential for Morocco is estimated to be 2,650 GW, while the technical wind energy potential is estimated to be 1,600 GW. Several projects have been realized in the areas of electricity production, interconnection to the national power grid, decentralized rural electrification and eventually the introduction of water pumping. It was concluded that exporting green energy to Europe, via the Morocco-Spain route after the restructuring of Morocco's electricity sector will create a viable market for the medium and long-term. 3 figs

    2012-09-25

    Wind turbines convert kinetic to electrical energy, which returns to the atmosphere as heat to regenerate some potential and kinetic energy. As the number of wind turbines increases over large geographic regions, power extraction first increases linearly, but then converges to a saturation potential not identified previously from physical principles or turbine properties. These saturation potentials are >250 terawatts (TW) at 100 m globally, approximately 80 TW at 100 m over land plus coastal ocean outside Antarctica, and approximately 380 TW at 10 km in the jet streams. Thus, there is no fundamental barrier to obtaining half (approximately 5.75 TW) or several times the world's all-purpose power from wind in a 2030 clean-energy economy.

    Utility-scale electricity produced from offshore wind farms has the potential to contribute significantly to the energy production of the United States. In order for the U.S. to rapidly develop these abundant resources, knowledgeable scientists and engineers with sound understanding of offshore wind energy systems are critical. This report summarizes the development of an upper-level engineering course in "Offshore Wind Energy Systems Engineering." This course is designed to provide students with a comprehensive knowledge of both the technical challenges of offshore wind energy and the practical regulatory, permitting, and planning aspects of developing offshore wind farms in the U.S. This course was offered on a pilot basis in 2011 at the University of Massachusetts and the National Renewable Energy Laboratory (NREL), TU Delft, and GL Garrad Hassan have reviewed its content. As summarized in this report, the course consists of 17 separate topic areas emphasizing appropriate engineering fundamentals as well as development, planning, and regulatory issues. In addition to the course summary, the report gives the details of a public Internet site where references and related course material can be obtained. This course will fill a pressing need for the education and training of the U.S. workforce in this critically important area. Fundamentally, this course will be unique due to two attributes: an emphasis on the engineering and technical aspects of offshore wind energy systems, and a focus on offshore wind energy issues specific to the United States.

    1995-01-01

    Twenty two windfarms are operational or are under construction in the U.K. They have a total installed capacity of approximately 140 MW and will generate about 360 GWh in a full year and provide the electricity needs of about 250 000 individuals and save the emission of about 400 000 tonnes of CO 2 each year. Developments so far have required an investment of about Pound 140 million provided mostly by banks and large corporate investors. Financing these projects has broken new ground for renewable technologies and established a framework for the financing of windfarms built using future NFFO contracts. Obtaining planning consents for these windfarms has involved thirteen public inquiries, eight of which have been successful. Four of these remain unused and the result of another is awaited. Statutory and other bodies have responded to the rapid deployment of windfarms by issuing guidelines and these together with Public Inquiry documentation now provide invaluable guidance for the industry. The U.K. market is arguably the most 'open' in Europe and Danish Wind Turbine manufacturers have gained over 50 per cent of the total market. A Japanese manufacturer has gained 25 per cent whilst the major U.K. turbine supplier has gained 17 per cent market share. There are still over thirty manufacturers worldwide and signs that a combination of innovation and market pressures are continuing to reduce the costs of wind energy. (author)

    The Wind Forecast Improvement Project (WFIP) is a public-private research program, the goals of which are to improve the accuracy of short-term (0-6 hr) wind power forecasts for the wind energy industry and then to quantify the economic savings that accrue from more efficient integration of wind energy into the electrical grid. WFIP was sponsored by the U.S. Department of Energy (DOE), with partners that include the National Oceanic and Atmospheric Administration (NOAA), private forecasting companies (WindLogics and AWS Truepower), DOE national laboratories, grid operators, and universities. WFIP employed two avenues for improving wind power forecasts: first, through the collection of special observations to be assimilated into forecast models to improve model initial conditions; and second, by upgrading NWP forecast models and ensembles. The new observations were collected during concurrent year-long field campaigns in two high wind energy resource areas of the U.S. (the upper Great Plains, and Texas), and included 12 wind profiling radars, 12 sodars, 184 instrumented tall towers and over 400 nacelle anemometers (provided by private industry), lidar, and several surface flux stations. Results demonstrate that a substantial improvement of up to 14% relative reduction in power root mean square error (RMSE) was achieved from the combination of improved NOAA numerical weather prediction (NWP) models and assimilation of the new observations. Data denial experiments run over select periods of time demonstrate that up to a 6% relative improvement came from the new observations. The use of ensemble forecasts produced even larger forecast improvements. Based on the success of WFIP, DOE is planning follow-on field programs.

  4. Wind energy harvesting with a piezoelectric harvester

    International Nuclear Information System (INIS)

    Wu, Nan; Wang, Quan; Xie, Xiangdong

    2013-01-01

    An energy harvester comprising a cantilever attached to piezoelectric patches and a proof mass is developed for wind energy harvesting, from a cross wind-induced vibration of the cantilever, by the electromechanical coupling effect of piezoelectric materials. The vibration of the cantilever under the cross wind is induced by the air pressure owing to a vortex shedding phenomenon that occurs on the leeward side of the cantilever. To describe the energy harvesting process, a theoretical model considering the cross wind-induced vibration on the piezoelectric coupled cantilever energy harvester is developed, to calculate the charge and the voltage from the harvester. The influences of the length and location of the piezoelectric patches as well as the proof mass on the generated electric power are investigated. Results show that the total generated electric power can be as high as 2 W when the resonant frequency of the cantilever harvester is close to the vortex shedding frequency. Moreover, a value of total generated electric power up to 1.02 W can be practically realized for a cross wind with a variable wind velocity of 9–10 m s −1 by a harvester with a length of 1.2 m. This research facilitates an effective and compact wind energy harvesting device. (paper)

    The report describes the Wind Energy Planning system (WEP). It is intended as a decision support system to be used in the economic evaluation of wind energy projects. Such projects could be minor projects with only a single wind turbine or large wind farm projects consisting of several wind turbine plants. In the WEP system, a wind turbine is described by data on initial investment, possible later reinvestments, O and M costs, expected yearly production, life time, and capacity factor. The raising of loans are modelled, too. Depending on which output report is created, the value of the wind generated electricity is calculated in two different ways: either the electricity is assumed to be sold at a price (time series) given by the user, or the alternative conventional power production is modelled by its specific investment, O and M costs, life time, effectivity, fuel mix, and time series for fuel prices. Using these data, capacity credit and saved fuel and O and M costs are calculated. Due to the flexible data structure of the model, the user can easily create a scenario that models a large scale introduction of wind power. In such a scenario the gradual build up through several years of the wind power capacity can be modelled. The report describes in detail the menu structure, the input facilities, the output reports, and the organization of data. Also included is an example with full input documentation and output reports. (au)

    China's massive carbon emissions and air pollution concerns have led its government to embrace clean energy innovation as a means of transitioning to a more sustainable energy system. We address the question of whether China's wind industry has become an important source of clean energy technology innovation. We find that in terms of wind capacity expansion, China has delivered enormous progress, increasing its wind capacity from virtually no wind capacity in the early 2000s to 140 GW by 2015. However, in terms of innovation and cost competitiveness, the outcomes were more limited: Chinese wind turbine manufacturers have secured few international patents and achieved moderate learning rates compared to the global industry's historical learning rate. Leading China-based indigenous producers are likely to remain important global players for the foreseeable future, but further progress in reducing the cost of capital equipment may slow relative to the recent past. However, opportunities in lowering curtailment rates and improving turbine quality can reduce China's overall levelized cost of electricity for wind. - Highlights: • Analyze wind power patenting trends of Chinese inventors and firms. • Many Chinese patents, though few were granted by foreign patent offices. • Chinese international patents are less likely to be cited than foreign counterparts. • China's wind industry managed to reduce production costs, but learning rate is low.

    Under this project, the Aleutian Pribilof Islands Association (APIA) conducted wind feasibility studies for Adak, False Pass, Nikolski, Sand Point and St. George. The DOE funds were also be used to continue APIA's role as project coordinator, to expand the communication network quality between all participants and with other wind interest groups in the state and to provide continued education and training opportunities for regional participants. This DOE project began 09/01/2005. We completed the economic and technical feasibility studies for Adak. These were funded by the Alaska Energy Authority. Both wind and hydro appear to be viable renewable energy options for Adak. In False Pass the wind resource is generally good but the site has high turbulence. This would require special care with turbine selection and operations. False Pass may be more suitable for a tidal project. APIA is funded to complete a False Pass tidal feasibility study in 2012. Nikolski has superb potential for wind power development with Class 7 wind power density, moderate wind shear, bi-directional winds and low turbulence. APIA secured nearly $1M from the United States Department of Agriculture Rural Utilities Service Assistance to Rural Communities with Extremely High Energy Costs to install a 65kW wind turbine. The measured average power density and wind speed at Sand Point measured at 20m (66ft), are 424 W/m2 and 6.7 m/s (14.9 mph) respectively. Two 500kW Vestas turbines were installed and when fully integrated in 2012 are expected to provide a cost effective and clean source of electricity, reduce overall diesel fuel consumption estimated at 130,000 gallons/year and decrease air emissions associated with the consumption of diesel fuel. St. George Island has a Class 7 wind resource, which is superior for wind power development. The current strategy, led by Alaska Energy Authority, is to upgrade the St. George electrical distribution system and power plant. Avian studies in Nikolski

    According to a recent study, global wind generating capacity increased by some 6800 MW in 2001, an annual growth of just over half the corresponding figure for 2000. 2001 was the third consecutive year in which new wind power capacity exceeded new nuclear power capacity, showing the maturity of wind power technology. Total installed wind power worldwide by the end of 2001 was close to 25.000 MW. Germany, Spain and Denmark are the main players, accounting for 56% of the world's capacity increase in 2001 and a total cumulative installed capacity of 14.750 MW, or 59% of the global total. The USA and India are also significant users of wind power; in 2001 the USA added 1700 MW of new installed capacity to become the world's second-largest market for wind power. The report Wind Force 10 outlines a scenario in which wind power provides 10% of the world's electricity by 2020, corresponding to a total installed capacity of 1200 GW. Risoe's System Analysis Department has looked at the possible future costs of electricity produced by wind turbines compared to conventional power. A learning curve analysis of historical data results in a progress ratio of 0,85. This means that for every doubling of the installed capacity, the cost of wind-generated electricity is reduced by 15%. Until recently the main driver for wind power has been a concern for greenhouse gases. Security of energy supply has now become an important issue, however, especially in Europe and the USA. Wind power plants can be erected at short notice and in a modular fashion that allows capacity to be added as required. The European Commission has supported wind power by sponsoring international research co-operation between institutes, universities and equipment manufacturers. The IEA supports worldwide co-operation, and has recently issued a report on the longterm R and D needs of wind energy.

    The purpose of this guideline is to establish a clear and consistent vocabulary for conveying offshore wind resource potential and to interpret this vocabulary in terms that are familiar to the oil and gas (O&G) industry. This involves clarifying and refining existing definitions of offshore wind energy resource classes. The terminology developed in this guideline represents one of several possible sets of vocabulary that may differ with respect to their purpose, data availability, and comprehensiveness. It was customized to correspond with established offshore wind practices and existing renewable energy industry terminology (e.g. DOE 2013, Brown et al. 2015) while conforming to established fossil resource classification as best as possible. The developers of the guideline recognize the fundamental differences that exist between fossil and renewable energy resources with respect to availability, accessibility, lifetime, and quality. Any quantitative comparison between fossil and renewable energy resources, including offshore wind, is therefore limited. For instance, O&G resources are finite and there may be significant uncertainty associated with the amount of the resource. In contrast, aboveground renewable resources, such as offshore wind, do not generally deplete over time but can vary significantly subhourly, daily, seasonally, and annually. The intent of this guideline is to make these differences transparent and develop an offshore wind resource classification that conforms to established fossil resource classifications where possible. This guideline also provides methods to quantitatively compare certain offshore wind energy resources to O&G resource classes for specific applications. Finally, this guideline identifies areas where analogies to established O&G terminology may be inappropriate or subject to misinterpretation.

    Strategic Power Systems (SPS) was contracted by Sandia National Laboratories to assess the feasibility of adapting their ORAP (Operational Reliability Analysis Program) tool for deployment to the wind industry. ORAP for Wind is proposed for use as the primary data source for the CREW (Continuous Reliability Enhancement for Wind) database which will be maintained by Sandia to enable reliability analysis of US wind fleet operations. The report primarily addresses the functional requirements of the wind-based system. The SPS ORAP reliability monitoring system has been used successfully for over twenty years to collect RAM (Reliability, Availability, Maintainability) and operations data for benchmarking and analysis of gas and steam turbine performance. This report documents the requirements to adapt the ORAP system for the wind industry. It specifies which existing ORAP design features should be retained, as well as key new requirements for wind. The latter includes alignment with existing and emerging wind industry standards (IEEE 762, ISO 3977 and IEC 61400). There is also a comprehensive list of thirty critical-to-quality (CTQ) functional requirements which must be considered and addressed to establish the optimum design for wind.

    Taxation of the energy industries is an issue of major importance for each energy sector. This has always been the situation for the primary fossil fuel sectors but, with corporatization and privatization, is now also an issue for the electricity supply industry. This article examines the most significant forms of taxation affecting the major industry sectors, namely secondary taxation, corporate taxation and, as a consequence of the corporatization and privatization of the electricity supply industry, surrogate taxation as it affects that industry. While essentially considering secondary taxation, the paper also reviews corporate and surrogate taxes. Tax exemptions for various energy sector activities such as mining operations, exploration and rehabilitation related activities are outlined. It is considered that there is insufficient evidence of the influence of taxation and other factors on electricity pricing. 2 tabs

    The wind power and PV are the key fields of clean energy development in China in recent years. However, there are still many aspects of problems in wind power and PV industries at present, such as the insufficient consumptive ability and the limitation of market competition capability. The effective leading and support of government in the aspect of policies is especially needed in order to solve these problems. Based on the analysis of main policies system of wind power and PV in our country, Spain, the United Kingdom and Germany are chosen as typical countries because of their wind power and PV industries are relatively developed. Their policies of wind power and PV industries are studied respectively from five aspects, namely macroscopic laws, development planning, administrative policies, fiscal and tax policies and price policies. Then the comparison among typical countries and China is made and the exiting problems in China's policies of wind power and PV industries are summed up. Finally, the suggestions to promote China's wind power and PV industries development are presented.

Many countries, such as Turkey, aim to increase the use of renewable and sustainable energy sources with different incentive mechanisms. In parallel with these incentive methods being implemented, wind energy capacity in Turkey has a remarkable increase in the growing rates of renewable energy sources according to installed wind power. Up to now, several wind power projects have been developed at different regions of Turkey. This paper aims to analyze the potential and development of wind energy systems in Turkey. Besides, the current usage and development of wind power installations have been explored for the World and Turkey in detail at the end of the 2011. Furthermore, this study also presents tax exemption, support, and incentive mechanisms to develop new wind energy investments in Turkey

    By 2020, greater use of wind energy could reduce carbon dioxide emissions by the U.S. energy sector by about 4.5%. However, greater effort is needed to address potentially negative impacts of this growing energy source, according to a new report from a committee of the U.S. National Research Council. Potential impacts of wind energy projects include deaths of birds and bats, reduced value of property located near a turbine, and habitat loss and fragmentation. However, because these are generally local projects, there is little information available to determine the cumulative effects of wind turbines over a whole region.

    This paper studies the Swedish component suppliers in the wind power industry. This group has not received much attention so far, and today very little is known. This study addresses the fact that the Swedish component suppliers have not been able to penetrate the wind power market despite the Swedish industry's strength in mechanical and electrical engineering. The aims of this paper were to gather information regarding the existing production and to identify factors that affect the Swedish component suppliers' scope to penetrate the wind turbine market. To date, although Sweden has spent considerable amounts of money on projects involving wind turbines, there is no series production of large wind turbines in Sweden. The historical development of the wind turbine industry suggests this alone would have inhibited the development of component production in Sweden. Yet, the country's proximity and good access to large wind turbine producing countries should be an advantage. Various factors and issues are identified and discussed in this paper that are relevant for the Swedish component suppliers' scope to penetrate the wind turbine market. These include market and product development, buyer-supplier relationships, export and sourcing behaviors, and time of market entry. This is a first step towards increasing the knowledge of Swedish component production and it is recognized that more studies are required. Various areas where relevant knowledge is largely missing or scarce are identified and discussed as well, and should serve as relevant starting points for continued research.

    This paper presents the performance evaluation and the design of the control system of a WECS (Wind Energy Conversion System) that employs a synchronous generator based on its digital simulation. The WECS discussed in this paper is connected to the utility grid through two Pulse Width Modulated (PWM) power converters. The structure of the proposed WECS enables us to achieve high performance energy conversion by: (i) maximizing the wind energy capture and (ii) minimizing the reactive power flowing between the grid and the synchronous generator. 8 refs., 19 figs.

  6. LIDAR and SODAR Measurements of Wind Speed and Direction in Upland Terrain for Wind Energy Purposes

    Directory of Open Access Journals (Sweden)

    Eamon McKeogh

    2011-08-01

    Full Text Available Detailed knowledge of the wind resource is necessary in the developmental and operational stages of a wind farm site. As wind turbines continue to grow in size, masts for mounting cup anemometers—the accepted standard for resource assessment—have necessarily become much taller, and much more expensive. This limitation has driven the commercialization of two remote sensing (RS tools for the wind energy industry: The LIDAR and the SODAR, Doppler effect instruments using light and sound, respectively. They are ground-based and can work over hundreds of meters, sufficient for the tallest turbines in, or planned for, production. This study compares wind measurements from two commercial RS instruments against an instrumented mast, in upland (semi-complex terrain typical of where many wind farms are now being installed worldwide. With appropriate filtering, regression analyses suggest a good correlation between the RS instruments and mast instruments: The RS instruments generally recorded lower wind speeds than the cup anemometers, with the LIDAR more accurate and the SODAR more precise.

    It is apparent the human need to use electricity in the current globalized world. And along with the social and industrial and beyond the everyday comfort evolution came the abuse of power. Aware that Brazil is used as an energy source originating from hydroelectric and that it does not include all domestic demand, should be studied energy sources that can assist it. Two clean and cheap energy alternatives which can contribute to reducing the environmental impacts such as global warming and water shortages are wind and nuclear energy. Which again, exhibit ideal characteristics to serve as alternative sources for electricity production, mainly in the dry season. (author)

    A Data acquisiton system developed for wind energy applications will be described in this paper. This system is composed of an anemometer with two blades downwind and a computer which processes wind data. Wind energy calculated from an average wind speed is inaccurate, since wind power increases with the cube of wind velocity. To decide the design and the site for a wind turbine system, it is very important to consider wind data on a long term basis, that is the total wind energy and distribu...

  12. Wind offering in energy and reserve markets

    Soares, T.; Pinson, P.; Morais, H.

    2016-09-01

    The increasing penetration of wind generation in power systems to fulfil the ambitious European targets will make wind power producers to play an even more important role in the future power system. Wind power producers are being incentivized to participate in reserve markets to increase their revenue, since currently wind turbine/farm technologies allow them to provide ancillary services. Thus, wind power producers are to develop offering strategies for participation in both energy and reserve markets, accounting for market rules, while ensuring optimal revenue. We consider a proportional offering strategy to optimally decide upon participation in both markets by maximizing expected revenue from day-ahead decisions while accounting for estimated regulation costs for failing to provide the services. An evaluation of considering the same proportional splitting of energy and reserve in both day- ahead and balancing market is performed. A set of numerical examples illustrate the behavior of such strategy. An important conclusion is that the optimal split of the available wind power between energy and reserve strongly depends upon prices and penalties on both market trading floors.

  13. Distributed energy systems with wind power and energy storage

    Energy Technology Data Exchange (ETDEWEB)

    Korpaas, Magnus

    2004-07-01

    The topic of this thesis is the study of energy storage systems operating with wind power plants. The motivation for applying energy storage in this context is that wind power generation is intermittent and generally difficult to predict, and that good wind energy resources are often found in areas with limited grid capacity. Moreover, energy storage in the form of hydrogen makes it possible to provide clean fuel for transportation. The aim of this work has been to evaluate how local energy storage systems should be designed and operated in order to increase the penetration and value of wind power in the power system. Optimization models and sequential and probabilistic simulation models have been developed for this purpose. Chapter 3 presents a sequential simulation model of a general wind hydrogen energy system. Electrolytic hydrogen is used either as a fuel for transportation or for power generation in a stationary fuel cell. The model is useful for evaluating how hydrogen storage can increase the penetration of wind power in areas with limited or no transmission capacity to the main grid. The simulation model is combined with a cost model in order to study how component sizing and choice of operation strategy influence the performance and economics of the wind-hydrogen system. If the stored hydrogen is not used as a separate product, but merely as electrical energy storage, it should be evaluated against other and more energy efficient storage options such as pumped hydro and redox flow cells. A probabilistic model of a grid-connected wind power plant with a general energy storage unit is presented in chapter 4. The energy storage unit is applied for smoothing wind power fluctuations by providing a firm power output to the grid over a specific period. The method described in the chapter is based on the statistical properties of the wind speed and a general representation of the wind energy conversion system and the energy storage unit. This method allows us to

  15. Skilful seasonal predictions for the European energy industry

    Science.gov (United States)

    Clark, Robin T.; Bett, Philip E.; Thornton, Hazel E.; Scaife, Adam A.

    2017-02-01

    We assess the utility of seasonal forecasts for the energy industry by showing how recently-established predictability of the North Atlantic Oscillation (NAO) in winter allows predictability of near-surface wind speed and air temperature and therefore energy supply and demand respectively. Our seasonal prediction system (GloSea5) successfully reproduces the influence of the NAO on European climate, leading to skilful forecasts of wind speed and wind power and hence wind driven energy supply. Temperature is skilfully forecast using the observed temperature-NAO relationship and the NAO forecast. Using the correlation between forecast NAO and observed GB electricity demand, we demonstrate that skilful predictions of winter demand are also achievable on seasonal timescales well in advance of the season. Finally, good reliability of probabilistic forecasts of above/below-average wind speed and temperature is also demonstrated.

  16. The wind energy potential in Argentina

    2005-01-01

    The wind energy are increasing its contribution to large scale electricity generation in many countries.The high technical maturity reached by modern wind turbines returns it viable and competitive in many regions, specially in those where a suitable legal framework stimulates the generation from renewable sources of energy.As this regard, the objective of this report is to demonstrate that, far from being limited to provide energy to remote, dispersed or geographically isolated sites not served by conventional networks, the wind energy has fully potential to supply a pretty relevant part of the electrical consumption of the great urban centers located in those zones of the country favored with this resource.For it, two preliminary estimations has done: the total 'windy' surface area in geographic proximity of the high voltage lines and electrical substations of the Argentine System of Interconnection (SADI) able 'to be seeded' with wind turbines, and the total electrical energy feasible of being generated from them.The paper supposes the exclusion of important non apt areas by virtue of strictly geographic, economic or environmental considerations.Even so, the result of the final calculation is extraordinarily high and promissory: if only 4% of the total surface of the contiguous land areas (in a maximum radius of 62 km) to the high voltage transmission system (in which the annual mean wind speed surpasses the 5.55 m/s) would be filled with power wind turbines, the annual average energy produced by them would be equivalent to 89% of the estimated national electrical consumption for year 2013.The usable wind potential in favorable technical conditions for commercial generation rounds this way around 40,000 MW, that would report an annual average energy of 100,000 GWh, occupying an area near 5000 km 2 .The total wind energy potential is (of course) considerably greater. Anyway, given the random nature of the wind and the consequent characteristics of not firm power

    Leanez, Frank J.; Drayton, Glenn

    2010-01-01

    Uncertainty in the electrical energy market is expected to increase with growth in the percentage of generation using renewable resources. Demand response can play a key role in giving stability to system operation. This paper discusses the embedded generation for industrial demand response in renewable energy markets. The methodology of the demand response is explained. It consists of long-term optimization and stochastic optimization. Wind energy, among all the renewable resources, is becoming increasingly popular. Volatility in the wind energy sector is high and this is explained using examples. Uncertainty in the wind market is shown using stochastic optimization. Alternative techniques for generation of wind energy were seen to be needed. Embedded generation techniques include co-generation (CHP) and pump storage among others. These techniques are analyzed and the results are presented. From these results, it is seen that investment in renewables is immediately required and that innovative generation technologies are also required over the long-term.

    The publication 'Wind Energy Statistics' is an annual publication. Since 2010, the reported statistics of installed power, number of plants and regional distribution, even semi-annually, and in tabular form on the Agency's website. The publication is produced in a new way this year, which will result in some data differ from previous publications. Due to the certificate system there is basically full statistics on wind energy in this publication which are presented in different styles. Here we present the regional distribution, ie. how the number of turbines and installed capacity is allocated to counties and municipalities. The electricity produced divided by county, where for reasons of confidentiality possible, are also reported. The wind power is becoming increasingly important in the Swedish energy system which provides an increased demand for statistics and other divisions than that presented in the official statistics. Therefore, this publication, which are not official statistics, has been developed.

    A two-phase project, intended to educate Nova Scotians about the potential of wind power to help reduce the province's greenhouse gas emissions, thereby fulfilling a vital role in Canada's effort to mitigate climate change effects, is described. First phase of the project involves gathering of wind data; the second the installation of a number of wind turbines throughout the province. The data gathering phase encompasses site selection, the actual data gathering for a period of about ten months, data analysis, and creation of a four or five module educational program, to be linked with intermediate high school science, mathematics, geography and social studies curriculum objectives to provide an interdisciplinary examination of these topics, and convey a sense of the complexity of the issues involved. The second phase of the project is intended to promote the possible use of wind energy in the province by installing a number of 25 kW wind turbines at selected sites throughout the province, followed by the gathering analysis of data relating to the amount of power produced by the turbines, calculating the efficiency of turbines and comparing data with the data gathered in previous years. The project is expected to last at least five years, exposing about 4000 high school students to hands-on involvement with issues of climate change and sustainable energy. Parents and the community will be exposed to these same issues indirectly, aided by the relative proximity of the weather stations to schools and the strategic location of the wind turbines. 4 refs

    2006-01-01

    Industrial Gases Companies have been mastering Hydrogen production, distribution, safe handling and applications for several decades for a wide range of gas applications. This unique industrial background positioned these companies to play a key role in the emerging Hydrogen Energy market, which can rely, at early stage of development, on already existing infrastructure, logistics and technical know-how. Nevertheless, it is important to acknowledge that Hydrogen Energy raised specific challenges which are not totally addressed by industrial gas activities. The main difference is obviously in the final customer profile, which differs significantly from the qualified professional our industry is used to serve. A non professional end-user, operating with Hydrogen at home or on board of his family car, has to be served with intrinsically safe and user-friendly solutions that exceed by far the industrial specifications already in place. Another significant challenge is that we will need breakthroughs both in terms of products and infrastructure, with development time frame that may require several decades. The aim of this presentation is to review how a company like Air Liquide, worldwide leader already operating more than 200 large hydrogen production sites, is approaching this new Hydrogen Energy market, all along the complete supply chain from production to end-users. Our contributions to the analysis, understanding and deployment of this new Energy market, will be illustrated by the presentation of Air Liquide internal development's as well as our participation in several national and European projects.

  13. Planners to the rescue: spatial planning facilitating the development of offshore wind energy.

    Science.gov (United States)

    2010-04-01

    The development of offshore wind energy has started to take place surprisingly quickly, especially in North European waters. This has taken the wind energy industry out of the territory of planning systems that usually govern the siting of wind farms on land, and into the world of departmental, sectoral regulation of marine activities. Although this has favoured the expansion of offshore wind energy in some respects, evidence suggests that the practice and principles of spatial planning can make an important contribution to the proper consideration of proposals for offshore wind arrays. This is especially so when a strategic planning process is put in place for marine areas, in which offshore wind is treated as part of the overall configuration of marine interests, so that adjustments can be made in the interests of wind energy. The current process of marine planning in the Netherlands is described as an illustration of this. (c) 2009 Elsevier Ltd. All rights reserved.

    This grant supported fundamental research into the characterization of flow parameters of relevance to the wind energy industry focused on offshore and the coastal zone. A major focus of the project was application of the latest generation of remote sensing instrumentation and also integration of measurements and numerical modeling to optimize characterization of time-evolving atmospheric flow parameters in 3-D. Our research developed a new data-constrained Wind Atlas for the Great Lakes, and developed new insights into flow parameters in heterogeneous environments. Four experiments were conducted during the project: At a large operating onshore wind farm in May 2012; At the National Renewable Energy Laboratory National Wind Technology Center (NREL NWTC) during February 2013; At the shoreline of Lake Erie in May 2013; and At the Wind Energy Institute of Canada on Prince Edward Island in May 2015. The experiment we conducted in the coastal zone of Lake Erie indicated very complex flow fields and the frequent presence of upward momentum fluxes and resulting distortion of the wind speed profile at turbine relevant heights due to swells in the Great Lakes. Additionally, our data (and modeling) indicate the frequent presence of low level jets at 600 m height over the Lake and occasions when the wind speed profile across the rotor plane may be impacted by this phenomenon. Experimental data and modeling of the fourth experiment on Prince Edward Island showed that at 10-14 m escarpment adjacent to long-overseas fetch the zone of wind speed decrease before the terrain feature and the increase at (and slightly downwind of) the escarpment is ~3–5% at turbine hub-heights. Additionally, our measurements were used to improve methods to compute the uncertainty in lidar-derived flow properties and to optimize lidar-scanning strategies. For example, on the basis of the experimental data we collected plus those from one of our research partners we advanced a new methodology to

    Three more or less reliable methods to determine the financial acceptance of the external effects of the use of wind energy are discussed. Attention is paid to the appreciation of external effects based on the environmental pollution or damage, appreciation based on prevented costs (implied valuation), and appreciation based on surveys, by which the willingness of the civilians to pay for a clean environment can be determined. A first indication of the environmental benefits of wind energy based on the above-mentioned methods is 0.04 to 0.08 DFl per kWh. For the total service life of a wind turbine this amounts to 800-1600 DFl per kW. The environmental benefits can be re-calculated in the form of subsidies, increasing the sellback prices or by means of an environmental levy on electric power generated by conventional power plants. 2 figs., 1 tab., 12 refs

  20. Wind of Change or Wind of Challenges: Implementation factors regarding wind energy development, an international perspective

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Countries promoting renewable energies encounter a variety of phenomena that can challenge the implementation of further onshore wind energy development. Those challenges can be observed in many multi-level governance systems, as exhibited in the U.S., Germany, and Mexico, where various regulatory and institutional levels must agree on goals and responsibilities. This is a challenge, as both forms of governance (top-down and bottom-up dominated are present in wind energy planning and policy. (1 Political and market phenomena, (2 siting issues, (3 the green vs. green dilemma, and (4 social acceptance are selected challenges within the different levels of decision-making processes in wind energy implementation. (1 Political and financial factors can influence the development by implementing incentive- and market-based policies, command-and-control policies, and feed-in tariffs. However, success of these policy designs for renewable energies is based on different political environments, and their electricity markets nationally, regionally, or statewide. (2 Spatial limitations in planning are created based on limited land availability due to conflicts with other land uses such as aviation, nature reserves, residential areas, their respective buffers. (3 The "green vs. green" dilemma involves the incoherent relationship between policies promoting renewable energies with policies protection species and their environments, becoming a major point of concern during siting and operations of wind energy. (4 Lastly, while there is a general overall support for wind energy, social acceptance on a local level is influenced by institutional settings i.e. information availability, as well as public and stakeholder concerns. Involvement in decision-making as well as financial participation (e.g. community-ownership affects public participation and acceptance. This paper goes into detail on these phenomena and discusses case studies in Europe and North America

    Turkey has very limited indigenous energy resources and has to import around 65% of primary energy to meet her needs. It is a large importer of primary energy despite having ample renewable energy sources. Turkey's vibrant economy has led to increased energy demand in recent years. This situation is expected to continue in the near future because its economy is dependent mainly on imported oil, natural gas and electricity. This paper presents the prevailing and the expected energy situation and energy demand. Wind energy potential in Turkey is also discussed. (author)

    Coastal and Great Lakes states account for nearly 80% of U.S. electricity demand, and the winds off the shores of these coastal load centers have a technical resource potential twice as large as the nation’s current electricity use. With the costs of offshore wind energy falling globally and the first U.S. offshore wind farm installed off the coast of Block Island, Rhode Island in 2016, offshore wind has the potential to contribute significantly to a clean, affordable, and secure national energy mix. To support the development of a world-class offshore wind industry, the U.S. Department of Energy has been supporting a broad portfolio of offshore wind research, development, and demonstration projects since 2011 and released a new National Offshore Wind Strategy jointly with the U.S. Department of the Interior in 2016.

    Full Text Available Wind energy applications and turbine installations at different scales have increased since the beginning of this century. As wind energy is an alternative clean energy source compared to the fossil fuels that pollute the atmosphere, systems that convert wind energy to electricity have developed rapidly. Turkey’s domestic fossil fuel resources are extremely limited. In addition, Turkey’s geographical location has several advantages for extensive use of wind power. In this context, renewable energy resources appear to be one of the most efficient and effective solutions for sustainable energy development and environmental pollution prevention in Turkey. Among the renewable sources, Turkey has very high wind energy potential. According to the Organization for Economic Cooperation and Development (OECD Turkey theoretically has 166 TWh a year of wind potential. However the installed wind power capacity is approximately 14% of total economical wind potential. In this study, Turkey’s installed electric power capacity and electric energy production are investigated and also the current situation of wind energy in Turkey is examined. The wind data used in this study were taken from Turkish Wind Energy Association (TUREB for the year 2012. This paper reviews the assessment of wind energy in Turkey as of the end of July 2012 including wind energy applications.

  18. Danish and Norwegian wind industry: The relationship between policy instruments, innovation and diffusion

    International Nuclear Information System (INIS)

    Buen, Jorund

    2006-01-01

    This article compares the role of policy instruments in stimulating long-term technological change in Danish and Norwegian wind industry. It concludes that although predictability has periodically been low, Denmark's broad portfolio of policies and measures has been well adapted to the different stages in the development of its wind industry. This has contributed to a high degree of innovation, successful establishment in niche markets, high degree of diffusion and establishment of domestic and international mass markets, and-in recent years-an increasingly successful replacement of senescent technology with new. The motivation of Norway's wind energy policies and measures-at least up until the late 1990s-has been to increase power supply rather than to stimulate industrial development and technological change. Policies and measures have been weaker than in Denmark; have been less stable over time; and stimulated the demand side much less. They have not sufficiently covered the wind industry's perceived needs on different stages in the development of new technology, and have not sufficiently stimulated continuous improvement, learning and new product development (dynamic efficiency) in industry. This has been part of the reason why there has been only a limited extent of innovation and diffusion of wind technology in Norway

  19. Evaluation of small wind turbines in distributed arrangement as sustainable wind energy option for Barbados

    International Nuclear Information System (INIS)

    Bishop, Justin D.K.; Amaratunga, Gehan A.J.

    2008-01-01

    The island of Barbados is 99% dependent on fossil fuel imports to satisfy its energy needs, which is unsustainable. This study proposes a 10 MW distributed wind energy scheme using micro wind turbines (WT) of horizontal (HAWT) and vertical axis (VAWT) configurations. These units are rated less than 500 W, and the scheme is hereafter referred to as mWT10. mWT10 is compared to the proposed 10 MW medium WT farm by the Barbados Light and Power Company (BL and P). The economic bottom line is the levelized cost of electricity (LCOE). The results highlight the BL and P proposal as the best economic option at BDS$0.19 per kWh, while that of both mWT10 configurations exceeds the conventional cost of BDS$0.25 by two to nine times. This is attributed to significantly higher relative installation and operational costs. However, the financial gap between mWT10 LCOE and the retail price of electricity is much smaller due to a large fuel surcharge passed on to each customer. Annual additional benefits of using wind energy include: greenhouse gas emissions savings of 6-23 kt of carbon dioxide; and anavoided fuel costs of BDS$1.5-5.3 million. The distributed mWT10 using HAWTs competes directly with the BL and P farm, however, it provides these benefits without the visual or ecological impacts of the larger machines. Conversely, VAWTs have features that favour a visually discrete and widely repeatable scheme but suffer relatively high costs. Therefore, this study illustrates the great potential of small wind turbines to be competitive with conventional wind farms, thus challenging the small wind industry to meet its potential by producing reliable and robust machines at lower cost.

    With over 5, 660 MW installed in end-2010, France ranks fourth in Europe, behind Germany, Spain and Italy. The wind power industry currently employs almost 11, 000 people in France throughout the value chain. In 2009, the first edition of this directory listed over one hundred companies working in around twenty different areas. Encouraged by these initial positive results, and with the help of ADEME, the French syndicate for renewable energies (SER) asked Capgemini Consulting to undertake a study to identify and raise awareness among French industrials likely to enter into the wind energy market. The French Ministry for Ecology, Energy, Sustainable Development and the Sea, along with the Ministry for the Economy, Finance and Employment, were involved in the work. 400 companies were questioned as part of the study. Over 150 replies testified to the dynamic character of the wind power market in France and overseas, and the opportunities for diversification that it represents for traditional industries like metallurgy, aeronautics, defence and shipyards, etc. The study led to the creation of the initiative Windustry France, which currently groups over 300 companies either active in the French wind power market or set to enter it. Windustry France is a showcase of the industrial know-how that can be used in the wind power industry both onshore and offshore. It includes local set-ups developed around major fields of activity (e.g. car industry, aeronautics, mechanics, etc.) and industrial port zones (Dunkerque, Rouen/Le Havre, Brest, Nantes Saint-Nazaire, Bordeaux, etc.). Several ministries, regional stakeholders and authorities are also involved (local authorities, Regional directorates for industry, research and the environment (DReal) networks and chambers of commerce and industry), all of which contribute to making Windustry France a collective approach to industrial policy.

    WIND-TO-HYDROGEN ENERGY PILOT PROJECT: BASIN ELECTRIC POWER COOPERATIVE In an effort to address the hurdles of wind-generated electricity (specifically wind's intermittency and transmission capacity limitations) and support development of electrolysis technology, Basin Electric Power Cooperative (BEPC) conducted a research project involving a wind-to-hydrogen system. Through this effort, BEPC, with the support of the Energy & Environmental Research Center at the University of North Dakota, evaluated the feasibility of dynamically scheduling wind energy to power an electrolysis-based hydrogen production system. The goal of this project was to research the application of hydrogen production from wind energy, allowing for continued wind energy development in remote wind-rich areas and mitigating the necessity for electrical transmission expansion. Prior to expending significant funding on equipment and site development, a feasibility study was performed. The primary objective of the feasibility study was to provide BEPC and The U.S. Department of Energy (DOE) with sufficient information to make a determination whether or not to proceed with Phase II of the project, which was equipment procurement, installation, and operation. Four modes of operation were considered in the feasibility report to evaluate technical and economic merits. Mode 1 - scaled wind, Mode 2 - scaled wind with off-peak, Mode 3 - full wind, and Mode 4 - full wind with off-peak In summary, the feasibility report, completed on August 11, 2005, found that the proposed hydrogen production system would produce between 8000 and 20,000 kg of hydrogen annually depending on the mode of operation. This estimate was based on actual wind energy production from one of the North Dakota (ND) wind farms of which BEPC is the electrical off-taker. The cost of the hydrogen produced ranged from $20 to $10 per kg (depending on the mode of operation). The economic sensitivity analysis performed as part of the

    Full Text Available The Smart Grid vision imposes a new approach towards energy supply that is more affordable, reliable and sustainable. The core of this new vision is the use of advanced technology to monitor power system dynamics in real time and identify system in stability. In order to implement strategic vision for energy management, it is possible to identify three main areas of investigation such as smart generation, smart grid and smart customer. Focusing on the latter topic, in this paper we present an application specifically designed to monitor an industrial site with particular attention to power consumption. This solution is a real time analysis tool, able to produce useful results to have a strategic approach in the energy market and to provide statistic analysis useful for the future choices of the industrial company. The application is based on a three layers architecture. The technological layer uses a Wireless Sensor Network (WSN to acquire data from the electrical substations. The middleware layer faces the integration problems by processing the raw data. The application layer manages the data acquired from the sensors. This WSN based architecture represents an interesting example of a low cost and non-invasive monitoring application to keep the energy consumption of an industrial site under control. Some of the added value features of the proposed solution are the routing network protocol, selected in order to have an high availability of the WSN, and the use of the WhereX middleware, able to easily implement integration among the different architectural parts.

    1999-01-01

    U.S. market activity has increased over the last two years. In 1998, new capacity totaled about 150 MW and projected 1999 capacity additions are over 600 MW. As the electricity market continues to evolve under restructuring, the U.S. Department of Energy (U.S. DOE) Wind Energy Program has positioned itself to work with industry to meet current challenges and opportunities, and prepare for the market of tomorrow. Some opportunities include green power markets and distributed applications, although a primary challenge involves the fact that avoided cost payments to renewable generators are not high enough to economically support projects. A recently incorporated power exchange in California, APX, Inc., has demonstrated that green power does attract a premium over prices on the conventional power exchange. The key elements of the U.S. DOE Wind Program are (1) Applied Research, which is critical for achieving advanced turbine designs capable of competing in a restructured market that emphasizes low cost generation; (2) Turbine Research, which supports the U.S. industry in developing competitive, high performance, reliable wind turbine technology for global energy markets; and (3) Cooperative Research and Testing, under which standards development and certification testing are the key activities for the current year

    Among the renewable energies, wind energy has gained the rapidest development in China. Moreover wind power generation has been penetrated into power system in a large scale. However, the high level wind curtailment also indicates a low efficiency of wind energy utilization over the last decade in China. One of the primary constraints on the utilization of wind energy is the lack of an electricity market, in which renewable energies can compete equally with traditional fossil fuel generation. Thus the new round electric power industry reform is essential in China. The reform involves implementing new pricing mechanism, introducing retail-side competition, promoting the consumption of renewable energy. The new round reform can be a promising solution for promoting the development and consumption of wind energy generation in China. Based on proposed reform policies of electric power industry, this paper suggests a roadmap for retail electricity market reform of China, which consists of three stages. Barriers to the efficient utilization of wind energy are also analysed. Finally, this paper introduces several efficient measures for mitigating wind curtailment in each stage of reform.

  1. Assessing Potential Wind Energy Resources in Saudi Arabia with a Skew-t Distribution

    KAUST Repository

    Tagle, Felipe

    2017-03-13

    Facing increasing domestic energy consumption from population growth and industrialization, Saudi Arabia is aiming to reduce its reliance on fossil fuels and to broaden its energy mix by expanding investment in renewable energy sources, including wind energy. A preliminary task in the development of wind energy infrastructure is the assessment of wind energy potential, a key aspect of which is the characterization of its spatio-temporal behavior. In this study we examine the impact of internal climate variability on seasonal wind power density fluctuations using 30 simulations from the Large Ensemble Project (LENS) developed at the National Center for Atmospheric Research. Furthermore, a spatio-temporal model for daily wind speed is proposed with neighbor-based cross-temporal dependence, and a multivariate skew-t distribution to capture the spatial patterns of higher order moments. The model can be used to generate synthetic time series over the entire spatial domain that adequately reproduces the internal variability of the LENS dataset.

The aim of the curriculum development project was to provide material for instructors to use in a training program to help professionals transition into careers in wind energy. Under this grant DNV KEMA established a knowledge boosting program for the wind energy industry with the following objectives: 1. Develop technical training curricula and teaching materials for six key topic areas that can be implemented in a flexible format by a knowledgeable instructor. The topic areas form a foundation that can be leveraged for subsequent, more detailed learning modules (not developed in this program). 2. Develop an implementation guidance document to accompany the curricula outlining key learning objectives, implementation methods, and guidance for utilizing the curricula. This curriculum is intended to provide experienced trainers course material that can be used to provide course participants with a basic background in wind energy and wind project development. The curriculum addresses all aspects of developing a wind project, that when implemented can be put to use immediately, making the participant an asset to U.S. wind industry employers. The curriculum is comprised of six short modules, together equivalent in level of content to a one-semester college-level course. The student who completes all six modules should be able to understand on a basic level what is required to develop a wind project, speak with a reasonable level of confidence about such topics as wind resource assessment, energy assessment, turbine technology and project economics, and contribute to the analysis and review of project information.

    This paper presents preliminary results of a study to evaluate the risk-reduction benefits of wind power for a case study utility system using decision analysis techniques. The costs and risks of two alternative decisions-whether to build a 400 MW gas-fired combined cycle plant or a 1600 MW wind plant in 2003-were compared through computer simulations as fuel prices, environmental regulatory costs, wind and conventional power plant availability, and load growth were allowed to vary. Three different market scenarios were examined: traditional regulation, a short-term power pool, and fixed-price contracts of varying duration. The study concludes that, from the perspective of ratepayers, wind energy provides a net levelized risk-reduction benefit of $3.4 to $7.8/MWh under traditional regulation, and less in the other scenarios. From the perspective of the utility plant owners, wind provides a significant risk benefit in the unregulated market scenarios but none in a regulated market. The methodology and findings should help inform utility resource planning and industry restructuring efforts. 2 figs., 3 tabs.

  6. About energy planning and wind energy after the Grenelle 2 Act

    International Nuclear Information System (INIS)

    Roche, C.

    2011-01-01

    With the Grenelle I and II Acts, the State has agreed to encourage the development of all renewable energy sources that can be economically viable, sustainable environmentally and to raise the share of sustainable energy to at least 23 % of final energy consumption by 2020, in accordance with its European commitments. Yet the Grenelle II Act, a 'legal monument', leaves one somewhat bemused on renewable energy matters. Far from simplifying applicable rules, it seems on the contrary to make procedures more complex by adding plans and guide-lines one on top of the other. Moreover, concerning 'facilities using the mechanical energy of wind', land sites seem to be paying the cost of stricter regulations with some facilities becoming Installations Classified for the Protection of the Environment (ICPE) and only the offshore wind energy industry seems to get real support by the Act.

    2004-03-01

    Wind energy is a pollution free and renewable resource widely distributed over China. Aimed at protecting the environment and enlarging application of wind energy, a new approach to application of wind energy by using compressed air power to some extent instead of electricity put forward. This includes: explaining the working principles and characteristics of the wind energy-compressed air power system; discussing the compatibility of wind energy and compressor capacity; presenting the theoretical model and computational simulation of the system. The obtained compressor capacity vs wind power relationship in certain wind velocity range can be helpful in the designing of the wind power-compressed air system. Results of investigations on the application of high-pressure compressed air for pressure reduction led to conclusion that pressure reduction with expander is better than the throttle regulator in energy saving.

  11. Optimal wind energy penetration in power systems: An approach based on spatial distribution of wind speed

    International Nuclear Information System (INIS)

    Zolfaghari, Saeed; Riahy, Gholam H.; Abedi, Mehrdad; Golshannavaz, Sajjad

    2016-01-01

    Highlights: • Chronological wind speeds at distinct locations of the wind farm are not the same. • Spatial distribution of wind speed affects wind farm’s output power expectation. • Neglecting wind speed’s spatial doubt leads to mistake in wind energy penetration. • Scenario-based method can be used for effective wind capacity penetration level. - Abstract: Contributing in power system expansions, the present study establishes an efficient scheme for optimal integration of wind energy resources. The proposed approach highly concerns the spatial distribution of wind speed at different points of a wind farm. In mathematical statements, a suitable probability distribution function (PDF) is well-designed for representing such uncertainties. In such conditions, it is likely to have dissimilar output powers for individual and identical wind turbines. Thus, the overall aggregated PDF of a wind farm remarkably influences the critical parameters including the expected power and energy, capacity factor, and the reliability metrics such as loss of load expectation (LOLE) and expected energy not supplied (EENS). Furthermore, the proposed approach is deployed for optimal allocation of wind energy in bulk power systems. Hence, two typical test systems are numerically analyzed to interrogate the performance of the proposed approach. The conducted survey discloses an over/underestimation of harvestable wind energy in the case of overlooking spatial distributions. Thus, inaccurate amounts of wind farm’s capacity factor, output power, energy and reliability indices might be estimated. Meanwhile, the number of wind turbines may be misjudged to be installed. However, the proposed approach yields in a fair judgment regarding the overall performance of the wind farm. Consequently, a reliable penetration level of wind energy to the power system is assured. Extra discussions are provided to deeply assess the promising merits of the founded approach.

    The paper describe possibilities of energy generation using various rotor types but especially with multi-blade wind engine operates in the areas with unfavourable wind condition. The paper presents also wind energy conversion estimation results presented based on proposed solution of multi-blade wind turbine of outer diameter of 4 m. Based on the wind distribution histogram from the disadvantage wind condition zones (city of Basel) and taking into account design and estimated operating indexes of the considered wind engine rotor an annual energy generation was estimated. Also theoretical energy generation using various types of wind turbines operates at disadvantage wind conditions zones were estimated and compared. The conducted analysis shows that introduction of multi-blade wind rotor instead of the most popular 3- blades or vertical axis rotors results of about 5% better energy generation. Simultaneously there are energy production also at very disadvantages wind condition at wind speed lower then 4 m s-1. Based on considered construction of multi-blade wind engine the rise of rotor mounting height from 10 to 30 m results with more then 300 % better results in terms of electric energy generation.

    In January 2010, the University of Minnesota, along with academic and industry project partners, began work on a four year project to establish new facilities and research in strategic areas of wind energy necessary to move the nation towards a goal of 20% wind energy by 2030. The project was funded by the U.S. Department of Energy with funds made available through the American Recovery and Reinvestment Act of 2009. $7.9M of funds were provided by DOE and $3.1M was provided through matching funds. The project was organized into three Project Areas. Project Area 1 focused on design and development of a utility scale wind energy research facility to support research and innovation. The project commissioned the Eolos Wind Research Field Station in November of 2011. The site, located 20 miles from St. Paul, MN operates a 2.5MW Clipper Liberty C-96 wind turbine, a 130-ft tall sensored meteorological tower and a robust sensor and data acquisition network. The site is operational and will continue to serve as a site for innovation in wind energy for the next 15 years. Project Areas 2 involved research on six distinct research projects critical to the 20% Wind Energy by 2030 goals. The research collaborations involved faculty from two universities, over nine industry partners and two national laboratories. Research outcomes include new knowledge, patents, journal articles, technology advancements, new computational models and establishment of new collaborative relationships between university and industry. Project Area 3 focused on developing educational opportunities in wind energy for engineering and science students. The primary outcome is establishment of a new graduate level course at the University of Minnesota called Wind Engineering Essentials. The seminar style course provides a comprehensive analysis of wind energy technology, economics, and operation. The course is highly successful and will continue to be offered at the University. The vision of U.S. DOE to
