    Houston, M.

    2001-01-01

    A new hydroelectric project is being proposed on the Peace River in the vicinity of Dunvegan, Alberta, by Glacier Power. The proposal calls for a low head, run-of-the-river hydroelectric power plant which would comprise a powerhouse containing 40 Kaplan turbines, a weir section, two fishways and a boat lock. The capacity of the generating plant would be 80 MW. As per established guidelines, the review process was initiated in July 1999 and is ongoing. Stakeholders, government agencies, both at the federal and provincial levels, are involved in the review process. The potential effects on the ice regime, fish passage and fish mortality and bank stability are the issues that have warranted the most attention to date. Scheduled to begin on October 2, 2001, a public hearing on the project has been arranged by the Alberta Energy and Utilities Board. The objective sought by Glacier Power is to have the project certified as being a green-power plant. Green power is defined as power produced from renewable sources with low environmental impact. The production of power with minimal environmental impacts is being encouraged in Alberta by Glacier Power, which sells power for a premium. 6 refs., 4 figs

    The village of Inukjuak in northern Quebec is not connected to the main electrical grid. This remote village is one of 14 Inuit communities in the Nunavik administrative region where electricity is generated by diesel thermal power plants under the direction of Hydro-Quebec Distribution's Isolated Grid subdivision. The heating of water and buildings is supplied by heavy fuel-oil. A compensation program for the price of fuel-oil is applied in the community. This presentation discussed the need for developing renewable energy sources in order to respond to the energy demands of isolated grids. The community of Inukjuak plans on developing the water resources of the Inukjuak River in order to produce hydroelectricity and reduce the use of diesel fuel. Several possible development sites were identified. The project will contribute to a reduction in energy costs while reducing greenhouse gas emissions. Revenues generated from the power plant will help the village in their economic development by enabling the completion of various community projects. The sustainable development approach taken for the project was discussed and the project's main technical, environmental and social issues were identified. The project is expected to reduce the production of an estimated 8 tons of carbon dioxide emissions by 2011 and nearly 15 tons after 10 years of operation.

The owners intend to proceed to the next step of negotiating a firm power purchase agreement.

  4. Instream flow needs below peaking hydroelectric projects

    International Nuclear Information System (INIS)

    Milhous, R.T.

    1991-01-01

    This paper reports on a method developed to assist in the determination of instream flow needs below hydroelectric projects operated in a peaking mode. Peaking hydroelectric projects significantly change streamflow over a short period of time; consequently, any instream flow methodology must consider the dual flows associated with peaking projects. The dual flows are the lowest flow and the maximum generation flow of a peaking cycle. The methodology is based on elements of the Physical Habitat Simulation System of the U.S. Fish and Wildlife Service and uses habitat, rather than fish numbers or biomas, as at basic response variable. All aquatic animals are subject to the rapid changes in streamflow which cause rapid swings in habitat quality. Some aquatic organisms are relatively fixed in location in the stream while others can move when flows change. The habitat available from a project operated in peaking mode is considered to be the minimum habitat occurring during a cycle of habitat change. The methodology takes in to consideration that some aquatic animals can move and others cannot move during a peaking cycle

    2009-03-22

    This study considered assessing the feasibility of developing small scale hydro-electric power from seven major tributaries within the Hoopa Valley Indian Reservation of Northern California (http://www.hoopa-nsn.gov/). This study pursued the assessment of seven major tributaries of the Reservation that flow into the Trinity River. The feasibility of hydropower on the Hoopa Valley Indian Reservation has real potential for development and many alternative options for project locations, designs, operations and financing. In order to realize this opportunity further will require at least 2-3 years of intense data collection focusing on stream flow measurements at multiple locations in order to quantify real power potential. This also includes on the ground stream gradient surveys, road access planning and grid connectivity to PG&E for sale of electricity. Imperative to this effort is the need for negotiations between the Hoopa Tribal Council and PG&E to take place in order to finalize the power rate the Tribe will receive through any wholesale agreement that utilizes the alternative energy generated on the Reservation.

    2017-08-01

    Sustainably developed and managed hydropower has enormous potential to contribute to global sustainability goals. It is known that hydroelectricity contributing small amounts to greenhouse gas emissions and other atmospheric pollutants. However, developing the remaining hydroelectric potential offers many challenges, and public pressure and expectations on the environmental and social performance of hydroelectric tend to increase over time. This paper aims to develop Systematic Sustainability Assessment (SSA) Tool that promotes and guides more sustainable hydroelectric projects in the context of Malaysia. The proposed SSA tool which not only provide a quality and quantitative report of sustainability performance but also act as Self-Assessment Report (SAR) to provide roadmap to achieve greater level of sustainability in project management for continuous improvement. It is expected to provide a common language that allow government, civil society, financial institutions and the hydroelectric sector to talk about and evaluate sustainability issues. The advantage of SSA tool is it can be used at any stage of hydroelectric development, from the earliest planning stages right through to operation.

    Girard, S.; Bouchard, B.

    2003-08-01

    Public hearings were held by the Bureau d'audiences publiques sur l'environnement concerning a proposed hydroelectric development project at Angliers, Quebec. The proposed hydroelectric plant is to be located at the outlet of the Des Quinze reservoir in the Temiscamingue region (northwest of the province). The site is within the municipality of Angliers, approximately 130 kilometres south of Rouyn-Noranda. The project will exploit the hydroelectric potential of the Ottawa River through a dam at Des Quinze reservoir, which is currently the property of the federal government. During the hearings, several issues were raised, and various topics examined. The political and administrative framework was reviewed, as well as the integration of the project within the community. The impacts, environmental as well as economic, were discussed. After careful examination of all the information, the Commission concluded that the hydroelectric project at Angliers was justified and acceptable from an environmental perspective. The expected economic impact on the community was an essential aspect in determining if the project was acceptable. refs., 4 figs

  13. Social and environmental impacts of the James Bay hydroelectric project

    International Nuclear Information System (INIS)

    Hornig, J.F.

    1999-01-01

    The book, which is an analysis and not an advocacy, examines the anatomy of the controversy that has swirled around the James Bay project - the La Grande and Great Whale projects combined - from the 1970s to the 1990s, and seeks, in the process, to determine whether there are lessons that can be learned from such an analysis that are applicable to other cases as well as to James Bay itself. The contributors are interested, at one and the same time, in finding ways to integrate the knowledge of natural scientists and social scientists to deepen the understanding of human/environment relations and to link science and policy to encourage a productive dialogue between practitioners and scholars in this increasingly important area of inquiry. The contributor's papers include the following: introduction to the issues; hydroelectric power development at James Bay: establishing a frame of reference; James Bay: environmental considerations for building large hydroelectric dams and reservoirs in Quebec; elevated mercury in fish as a result of the James Bay hydroelectric power development: perception and reality; the Cree people of James Bay: assessing the social impacts of hydroelectric dams and reservoirs; culture, social change, and Cree opposition to the James Bay hydroelectric development; and the impact of James Bay hydroelectric development on the art and craft of the James Bay Cree. The authors of the volume have attempted to stand back and examine just a few of these issues from the perspective of a variety of disciplines, and their purpose is to inform and stimulate thoughtful consideration by providing an overall perspective that might might serve to broaden the context in which specific issues can be debated. refs., 3 tabs., 5 figs

  1. Indian areas threatened by hydroelectric projects in Brazil

    Energy Technology Data Exchange (ETDEWEB)

    Aspelin, P L; Santos, S.C. dos

    1981-10-01

    In Brazil, as elsewhere, high priority is being given to developing domestic energy sources due to the spectacular increase in the cost of imported petroleum in recent years. This paper discusses the present situation of the thirty-two to thirty-four various Indian areas presently known to be threatened by seven major hydro-electric projects and one flood-control project, either planned or underway, in or directly involving Brazil. A total of at least 100,000 hectares of Indian land (or nearly one hectare for each remaining Brazilian Indian) will be flooded or otherwise expropriated by these projects. Past efforts by the Brazilian National Indian Foundation (FUNAI) to protect the Indians from the pressure of ''national development'' have not been sufficient. Research, planning, publicity, and political pressure are necessary to ensure that their efforts regarding these hydroelectric projects are more successful.

    This paper is based on a study conducted for the World Bank which evaluated the feasibility of developing an empirically based ex ante project analysis system for hydroelectric projects. The system would be used to assess: the reasonableness of engineering-based cost and schedule estimates used for project appraisal and preliminary estimates used to select projects for appraisal; and the potential for cost growth and schedule slip. The system would help identify projects early in the project appraisal process that harbor significantly higher than normal risks of overrunning cost and schedule estimates

  6. Mrica Hydroelectric Project: a study in partnering

    International Nuclear Information System (INIS)

    Loraine, R.K.; Bannmark, O.

    1993-01-01

    This paper describes the contractual and financial aspects of the Mrica Project. Of particular interest is the high degree of cooperation that developed between the various parties, and the effect this had on the progress and completion of the project. This relationship had its origin in the need to make the best use of the relatively scarce funds available. It was vitally important that problems were solved jointly and that costs did not escalate as a result of confrontation between the parties. In this respect, the project was an early manifestation of the contractual relationship now called partnering, and the procedures adopted at Mrica are very similar to those now widely used in partnering contracts. The paper is therefore structured to identify and analyse the key elements of co-operation, and their impact on both the negotiation of the contracts and the completion of the works. (Author)

  10. Benefits of fish passage and protection measures at hydroelectric projects

    International Nuclear Information System (INIS)

    Cada, G.F.; Jones, D.W.

    1993-01-01

    The US Department of Energy's Hydropower Program is engaged in a multi-year study of the costs and benefits of environmental mitigation measures at nonfederal hydroelectric power plants. An initial report (Volume 1) reviewed and surveyed the status of mitigation methods for fish passage, instream flows, and water quality; this paper focuses on the fish passage/protection aspects of the study. Fish ladders were found to be the most common means of passing fish upstream; elevators/lifts were less common, but their use appears to be increasing. A variety of mitigative measures is employed to prevent fish from being drawn into turbine intakes, including spill flows, narrow-mesh intake screens, angled bar racks, and lightor sound-based guidance measures. Performance monitoring and detailed, quantifiable performance criteria were frequently lacking at non-federal hydroelectric projects. Volume 2 considers the benefits and costs of fish passage and protection measures, as illustrated by case studies for which performance monitoring has been conducted. The report estimates the effectiveness of particular measures, the consequent impacts on the fish populations that are being maintained or restored, and the resulting use and non-use values of the maintained or restored fish populations

  17. Final Technical Report - Modernization of the Boulder Canyon Hydroelectric Project

    Energy Technology Data Exchange (ETDEWEB)

    Taddeucci, Joe [Dept. of Public Works, Boulder, CO (United States). Utilities Division

    2013-03-29

    The Boulder Canyon Hydroelectric Project (BCH) was purchased by the City of Boulder, CO (the city) in 2001. Project facilities were originally constructed in 1910 and upgraded in the 1930s and 1940s. By 2009, the two 10 MW turbine/generators had reached or were nearing the end of their useful lives. One generator had grounded out and was beyond repair, reducing plant capacity to 10 MW. The remaining 10 MW unit was expected to fail at any time. When the BCH power plant was originally constructed, a sizeable water supply was available for the sole purpose of hydroelectric power generation. Between 1950 and 2001, that water supply had gradually been converted to municipal water supply by the city. By 2001, the water available for hydroelectric power generation at BCH could not support even one 10 MW unit. Boulder lacked the financial resources to modernize the facilities, and Boulder anticipated that when the single, operational historical unit failed, the project would cease operation. In 2009, the City of Boulder applied for and received a U.S. Department of Energy (DOE) grant for $1.18 million toward a total estimated project cost of $5.155 million to modernize BCH. The federal funding allowed Boulder to move forward with plant modifications that would ensure BCH would continue operation. Federal funding was made available through the American Recovery and Reinvestment Act (ARRA) of 2009. Boulder determined that a single 5 MW turbine/generator would be the most appropriate capacity, given the reduced water supply to the plant. Average annual BCH generation with the old 10 MW unit had been about 8,500 MW-hr, whereas annual generation with a new, efficient turbine could average 11,000 to 12,000 MW-hr. The incremental change in annual generation represents a 30% increase in generation over pre-project conditions. The old turbine/generator was a single nozzle Pelton turbine with a 5-to-1 flow turndown and a maximum turbine/generator efficiency of 82%. The new unit is a

  1. Hydro-electric power project on the Toulnustouc River

    International Nuclear Information System (INIS)

    Rochon, Y.; Morneau, J.; Lefebvre, G.

    2001-01-01

    Hydro-Quebec has proposed the development of a hydro-electric power project on the Toulnustouc River, located between Saint-Anne Lake and Manic Reservoir. The work would involve the construction of a power generation plant of 526 MW, construction of a 77 m dam on the Toulnustouc River, 14 km downstream from the existing Lac-Saint-Anne dam, the creation of a new water expanse covering 22 square kilometers, the construction of an embankment, the strengthening of the existing Saint-Anne embankment, digging a 9.8 km gallery, and the construction of a flood spillway. This work would have consequences for three different sectors of the river: between the existing and the proposed dam, between the dam and the projected power plant, and between the power plant and the limit of the influence of the reservoir Manic-2. Hydro-Quebec would like the work to begin in July 2001, with the aim of having the plant in operation in 2005. The overall cost of the project is estimated at 600 million dollars. It is expected that the economic benefits for the region would be in the 211 million dollar range. An environmental assessment of the entire project was performed by Quebec Ministere de l'Environnement. The authors determined that the project was recognized as justified by the Ministere des Ressources Naturelles (Natural Resources Ministry) and concluded that the project was acceptable from an environmental point of view as long as six conditions were met. They touched on the construction of a flood spillway capable of evacuating 19 cubic meters per second at any time during the year, that water be evacuated downstream following a pre-determined debit that varies according to the time of year, monitoring of the brook trout population and its habitat, and environmental monitoring. 46 refs., 7 tabs., 2 figs., 1 annex

    This study examines envirorunental mitigation practices that provide upstream and downstream fish passage and protection at hydroelectric projects. The study includes a survey of fish passage and protection mitigation practices at 1,825 hydroelectric plants regulated by the Federal Energy Regulatory Commission (FERC) to determine frequencies of occurrence, temporal trends, and regional practices based on FERC regions. The study also describes, in general terms, the fish passage/protection mitigation costs at 50 non-Federal hydroelectric projects. Sixteen case studies are used to examine in detail the benefits and costs of fish passage and protection. The 16 case studies include 15 FERC licensed or exempted hydroelectric projects and one Federally-owned and-operated hydroelectric project. The 16 hydroelectric projects are located in 12 states and range in capacity from 400 kilowatts to 840 megawatts. The fish passage and protection mitigation methods at the case studies include fish ladders and lifts, an Eicher screen, spill flows, airburst-cleaned inclined and cylindrical wedgewire screens, vertical barrier screens, and submerged traveling screens. The costs, benefits, monitoring methods, and operating characteristics of these and other mitigation methods used at the 16 case studies are examined.

    LeDrew, L.; Bastien, J.; Tremblay, A.

    2007-01-01

    Newfoundland and Labrador Hydro has proposed to develop the hydroelectric potential of the lower Churchill River by constructing generating facilities at Gull Island and Muskrat Falls. This paper presented the results of a study that was conducted to collect baseline data on greenhouse gas (GHG) fluxes/emissions of carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O) from the lower Churchill River, Smallwood reservoir, and natural lakes in the upper and lower Churchill regions. The purpose of the study was to compare GHG fluxes between the lower Churchill River, Smallwood reservoir and those of the nearby natural lakes and to compare GHG fluxes between the Smallwood reservoir and those of boreal reservoirs in northern Quebec. The paper provided a description of the site and the methodology for GHG flux measurement. The results and discussion focused on physical-chemical variables and GHG fluxes. The study results were to be used in the environmental assessment of the project. It was concluded that the lower Churchill River has higher CO 2 fluxes and lower CH 4 fluxes than the Smallwood reservoir and higher CO 2 fluxes than natural lakes in the region. There was no significant difference in N 2 O fluxes between the sampled waterbodies. Both CO 2 and CH 4 fluxes from the lower Churchill River were comparable to other Canadian reservoirs. 12 refs., 2 tabs., 6 figs

    International Nuclear Information System (INIS)

    1999-01-01

    The British Columbia Environmental Assessment Office has reviewed an application by Canadian Hydro Developers (B.C.) Inc., to develop the Pingston Hydroelectric Project, a run-of-river facility, located 60 km south of Revelstoke, British Columbia. The review includes an evaluation of any social and environmental impacts, including the effects on migratory birds, small mammals, amphibians, fish, wildlife, water quality, noise and visual aspects, that would be associated with the project. One consideration in selecting the project site was its ease of access along existing roadways and close proximity to power lines, another, the absence of any potential effects on fish and fish habitat. The project is also expected to have a negligible effect on water quality- related matters such as sediment transport, nutrient trapping in the headpond, and movement of large organic debris through the system. The project will not impact on archaeological resources, offers a renewable supply of energy and represents an overall positive effect on air quality for British Columbia. BC Hydro has committed to providing electrical interconnection to the main grid. 9 refs., 5 tabs., 14 figs., 9 appendices

  5. Hydroelectric power plant project on the Coulonge River: Report of inquiry and public hearing

    International Nuclear Information System (INIS)

    1992-01-01

    A hydroelectric power plant is proposed for the Coulonge River, a tributary of the Ottawa River in Quebec. Water would be taken from the river through a 609 m tunnel to the plant, which would contain two Francis turbines with a total installed power of 16.2 MW operating under a net head of 43 m and a water flow rate of 21.5 m 3 /s. Other works would be necessary upstream for controlling flow and protecting the intake. Total cost for the two-year construction project is estimated at $28 million and annual revenues are forecast at $6 million. An inquiry and public hearing were held to consider the biophysical, social, economic, and cultural impacts of the proposed hydroelectric project. Results of the hearing are summarized in such areas as legal aspects, environmental quality, water rights, land use, job creation, effects on tourism and recreation, effects on wildlife, water level fluctuations, water quality, and safety. The economic justification for the project is discussed with reference to electricity demand, economic viability, utilization factors, and policies that favor construction of small-scale hydroelectric plants. The project was not found to bring sufficient benefits to the region in which it was to be situated and would not be authorized unless Hydro-Quebec tariff policy with respect to small hydro plants was modified and unless the project sponsor compensates the regional municipality. 13 refs., 11 figs., 4 tabs

    Harvey, A.; Journault, C.

    2004-08-01

    Public hearings were held by Quebec's Bureau d'audiences publiques sur l'environnement (BAPE) concerning a proposed hydroelectric development project on the Magpie River in Quebec's Minganie Region. The proposed hydroelectric power plant is to be developed and managed by Hydromega Services Inc. and constructed by Aecon Group Ltd. The project consists of reconstructing a power plant and dam at an existing site that was constructed in 1961 but which has been decommissioned since 1989. The installed capacity of the proposed power plant is 40.6 MW. The drop height for the dam is 21.25 metres. The issues that were addressed during the hearings included the opinions and suggestion of the participants regarding energy provisions, regional development and ecological protection. One of the main concerns facing this project is the loss of spectacular rapids currently used by rafters. The Commission noted that the rapids cannot be saved without significant modification to the design of the project. However, the flooding associated with the project would facilitate fishermen, canoeists and kayakers, thereby preserving the recreational and tourism attributes of the Magpie River. The Commission also noted that the local economic repercussions of the project would benefit the population of the Minganie Region which has a high unemployment rate. Any ecological impacts may be controlled by relevant attenuation measures and follow-up. It was concluded that the proposed project could contribute modestly to meeting the anticipated growth in energy demand in Quebec. refs., figs

    Saounatsou, Chara; Georgi, Julia

    2014-08-01

    The Polyphyto Hydroelectric Project was constructed in 1974 and it has been operating since on the Aliakmonas River, Kozani prefecture, by the Greek Public Power Corporation. The construction of the Ilarion Hydroelectric Project, upstream from the Polyphyto Reservoir, has been recently completed and will start operating in the near future. Apart from hydroelectric power production, the Polyphyto reservoir provides flood control to the areas below the Polyphyto dam. It is also used to manage water provision to the city of Thessaloniki and adjacent agricultural plain, providing at the same time cooling water to the Thermo Electric Projects in Ptolemaida. The Polyphyto reservoir has potential for further development as an economic fulcrum to the region in which is located. The Kozani and Servia-Velvendos Municipalities have proceeded to the construction of several touristic, nautical - athletic and fishing projects. In order to promote such developments, while preserving the artificial wetland, flora and fauna of the Polyphyto Reservoir, it is important to reduce the fluctuation of the reservoir elevation which according to its technical characteristics is 21m. The aim of this paper is to propose the combined operation of the two Hydroelectric Project reservoirs to satisfy all the present Polyphyto Hydroelectric Project functions and to reduce the annual fluctuation of the Polyphyto Reservoir. The HEC-5, Version 8 / 1998 computer model was used in our calculations, as developed by the Hydrologic Engineering Center (HEC) of the US Army Corps of Engineers for reservoir operation simulation. Five possible operation scenarios are tested in this paper to show that the present fluctuation of the Polyphyto Reservoir can be reduced, with some limitations, except during dry weather periods.

The project involves the construction of a headrace canal, intake, tunnel, powerhouse, access roads, electrical transmission line, spillway, weir and a bridge over the Sheldrake River. The proposed development was subject to an environmental evaluation process and public consultation. Quebec's environmental public hearing board held a public hearing on the draft development of the project to hear the concerns and views of the public and stakeholders. The hearing focused on a number issues, such as reasons for the project, its location and socio-economic impacts. The cumulative environmental effects of the project were also examined. The primary concerns were the economic repercussions of the project and its effect on tourism and fish, including salmon. The Board determined that the project would create jobs in a region affected by unemployment and the decay of its municipalities and that it would stimulate the local and regional economy. However, the Board determined that changes to the project are required to minimize impacts on the natural environment. The project proponent must monitor instream flows to ensure that fish passage facilities meet regulations. In addition, since the proposed project crosses 3 bogs, the developer must compensate for lost wetlands. A 10-year follow-up is required to assess the recovery of these environments. The developer must also maintain the aesthetic quality of the Courbe du Sault Falls in order to maintain the eco-tourism in the region. refs., figs.

  3. Externality costing for hydroelectric projects: Is it desirable? Is it possible?

    1992-01-01

    The assignment of monetary values to environmental and social impacts of hydroelectric projects is discussed. The strengths and weaknesses of the economic approach to externality costing are noted. The problem to be faced is that environmental externalities associated with a hydro project very often involve resources that have little or no relation with the market, such as disturbances of land not used for commercial activities. The valuation of externalities related to thermal power plants is examined to provide lessons for quantifying the externalities of hydro projects. One observation is that there is very little information on the real impacts of such phenomena as the release of greenhouse gases, making quantification of their effect difficult; another is that impacts from atmospheric emissions are well in excess of simple deterioration of material goods or recreational activities that have some relationship to the market. Applied to hydro projects, the lessons from these observations indicate that there are no exact and homogeneous measurement units for impacts of actions such as diking or alteration of wildlife habitats. One approach that has been tried is the contingent valuation method, which relies on asking respondents how much they would pay to avoid an impact or risk. This approach is criticized and it is suggested to experiment with a review of the tradeoffs between several possible environmental impacts defined in a precise manner

    A mathematical model for energetic and economic evaluation of hydroelectric projects is developed. The main advantage of the proposed methodology is that the model considers uncertainty and vagueness which appears during the decision making process. Due to modeling of variables that are non statistical in their character, fuzzy logic approach is fully incorporated in the model. The first step in energetic evaluation of the hydro power projects is determination of the characteristic of the efficiency of the units to be installed in hydro power plants. For this purpose the model which uses the best characteristics of Artificial Network Fuzzy Inference System (ANFIS) is applied. The method is tested on real systems: HPP Tikves- the power plant in operation and HPP Kozjak - the power plant in construction. The results obtained from practical implementation show that the proposed approach gives superior results than classical polynomial approximation. The model for determining the consumption characteristic of hydro power plant is developed by Sugeno Fuzzy Logic System with polynomials in the consequent part of the rules. Model takes into account the variable gross head of HPP, as well as, the number of units which will be in operation for given output. Modeling of the gross head and power output are performed by expert's design membership functions. This model is practically applied on HPP Tikves for determination of the consumption characteristic for several gross head. The plausible yearly production of electricity from hydro power project, which is important for estimation of the benefit from the project, is calculated by mixed fuzzy-statistical model. hi this approach fuzzy set of the inflow is constructed according to the statistical parameters. The calculation of the production of electricity is realized for a several hydrological conditions which are described by linguistic variables. Finally, Mamdani Fuzzy Inference System with fuzzy number in consequent part

    2004-01-01

    This report presents the results of an environmental assessment of Hydro-Quebec's proposed project to build a new facility on the Peribonka River. The facility includes a run-of-river generating station with an installed capacity of 385 MW. The Quebec Region of the Department of Fisheries and Oceans Canada has conducted an environmental assessment of the project's effects. A summary of the project and the environment in which it will be carried out was presented along with the results of public consultations conducted by Hydro-Quebec. A summary of the main environmental effects was included along with cumulative effects and the effects caused by accidents or malfunctions that may occur. In addition, the terms and conditions of mitigation measures and follow-up programs were described and the significance of any environmental impacts were assessed. The project includes the construction of a 80 metre high dam, two dikes and one spillway upstream of the mouth of the Manouane River. The level of the reservoir would remain at close to its maximum level of 244.2 metres to optimize hydroelectric production. The power house would be integrated into the Hydro-Quebec transmission network. The main impacts of the project would result from the construction of the reservoir, the encroachment caused by associated facilities and the changes in hydrological conditions. This report outlined the current use of lands and resources for traditional purposes by Aboriginals. It also discussed the effects of natural events such as flooding, waves and climate that may cause damage to the facilities. It was determined that the project is not likely to cause significant effects on the renewable resources of the forest and the fisheries. The Department of Fisheries and Oceans, after having taking into account proposed mitigation measures, has rendered a preliminary conclusion which states that the project is not likely to have significant negative environmental effects. 29 refs., 7 tabs., 2

    Great Lakes Power recently constructed a hydroelectric plant on the Magpie River near Wawa, Ontario. The project involved three main elements: construction of a 33 m high dam, a 15.5 MW power station, and a spillway at Steephill Falls; construction of a 3.5 m high overflow weir just above the crest of scenic Magpie Falls, creating a head pond to supply a 15 MW power plant; and construction of a weir and 15 MW power plant at Mission Falls. Although this was a private development and therefore not automatically subject to Ontario's Environmental Assessment Act, Great Lakes Power decided to conform with the act's requirements and undertook a comprehensive environmental assessment (EA). Environmental issues were focused on changes in hydrology and water quality, impacts on fisheries and natural resources, slope stability and erosion, socioeconomic impacts, impacts on heritage resources, and impacts on tourism and recreation. The project was approved subject to conditions which included implementation of mitigation and monitoring requirements outlined in the EA document. Environmental specialists worked closely with the engineers at the detailed design stage of the project, resulting in modifications to the preliminary design to minimize environmental impacts

    Construction of the Lake Robertson hydroelectric project on Quebec`s Lower North Shore was discussed in detail. The dam and powerhouse, located on the HaHa River, consists of a 134 m long concrete gravity dam, and a 21 MW powerhouse with two 69 kV transmission lines and four substations. The climate, terrain, and geography of the region, all of them characterized as severe, and the logistics of construction of the dam and power lines, aggravated by the isolation and severe conditions at the site, were described. The roller compacted concrete design and construction were noted, and justification for a concrete dam over an earth-fill dam was provided. Economics, properties, and composition of the roller compacted concrete (RCC) were examined, and control test results for the RCC concrete were provided. The use of RCC for the Lake Robertson development was described as successful in terms of the quality, watertightness, and completion time. The experience gained by the participants will make it possible to offer RCC as an alternative on various other projects. 2 figs.

    1990-01-01

    On Milos island (Aegean Sea) a high enthalpy, water dominated geothermal field of high salinity exists. At 1985, a 2MW geothermoelectric pilot plant was installed on the island. This plant has been provided by Mitsubishi Heavy Industries of Japan under a contract with Public Power Corporation of Greece. Due to high salinity of the geothermal fluid, unforeseen problems (scaling mainly) arisen in both steam and brine cycles. As a consequence, the operation (trial mainly) of the power plant have been interrupted several times for long periods, in order to identify the arisen, each time, problems and find the most appropriate technical solution. The above fact, as well as, some unfortunate coincidences described in this paper, led Milos people to react against geothermal development in their island. The sequence of the events, technical and non-technical, their approach and the relevant conclusions are reported in this presentation

    On January 27, 2010 the City of North Little Rock, Arkansas received notification of the awarding of a Department of Energy (DOE) grant totaling $450,000 in funding from the American Recovery and Reinvestment Act (ARRA) under the Project Title: Recovery Act: Hydroelectric Facility Improvement Project – Automated Intake Clearing Equipment and Materials Management. The purpose of the grant was for improvements to be made at the City’s hydroelectric generating facility located on the Arkansas River. Improvements were to be made through the installation of an intake maintenance device (IMD) and the purchase of a large capacity wood grinder. The wood grinder was purchased in order to receive the tree limbs, tree trunks, and other organic debris that collects at the intake of the plant during high flow. The wood grinder eliminates the periodic burning of the waste material that is cleared from the intake and reduces any additional air pollution to the area. The resulting organic mulch has been made available to the public at no charge. Design discussion and planning began immediately and the wood grinder was purchased in July of 2010 and immediately put to work mulching debris that was gathered regularly from the intake of the facility. The mulch is currently available to the public for free. A large majority of the design process was spent in discussion with the Corps of Engineers to obtain approval for drawings, documents, and permits that were required in order to make changes to the structure of the powerhouse. In April of 2011, the City’s Project Engineer, who had overseen the application, resigned and left the City’s employ. A new Systems Mechanical Engineer was hired and tasked with overseeing the project. The transfer of responsibility led to a re-examination of the original assumptions and research upon which the grant proposal was based. At that point, the project went under review and a trip was booked for July 2011 to visit facilities that currently

The Pacific Island Health Care Project (PIHCP) provides humanitarian medical referral/consultation/care to >500,000 indigenous people of these remote islands. In the mid-1990s, we developed a simple store-and-forward program to link the USAPI with Tripler Army Medical Center. This application allowed image attachment to email consultations. More than 8000 Pacific Islanders have benefited from the program. Three thousand Pacific Islanders prior to telemedicine (1990-1997) and since store-and-forward telemedicine (1997-present), the PIHCP has helped an additional 5000. Records post dynamically and are stored in an archival database. The PIHCP is the longest running telemedicine program in the world delivering humanitarian medical care. It has bridged the Developing World of the remote Pacific Islands with advanced medical and surgical care available at a major US military teaching hospital.

  16. Fish passage mitigation of impacts from hydroelectric power projects in the United States

    International Nuclear Information System (INIS)

    Cada, G.F.

    1996-01-01

    Obstruction of fish movements by dams continues to be the major environmental issue facing the hydropower industry in the US. Dams block upstream migrations, which can cut off adult fish form their historical spawning grounds and severely curtail reproduction. Conversely, downstream-migrating fish may be entrained into the turbine intake flow and suffer turbine-passage injury or mortality. Hydroelectric projects can interfere with the migrations of a wide variety of fish. Maintenance, restoration or enhancement of populations of these species may require the construction of facilities to allow for upstream and downstream fish passage. The Federal Energy Regulatory Commission (FERC), by law, must give fish and wildlife resources equal consideration with power production in its licensing decisions, must be satisfied that a project is consistent with comprehensive plans for a waterway (including fisheries management plans), and must consider all federal and state resource agency terms and conditions for the protection of fish and wildlife. As a consequence, FERC often requires fish passage mitigation measures as a condition of the hydropower license when such measures are deemed necessary for the protection of fish. Much of the recent research and development efforts of the US Department of Energy's Hydropower Program have focused on the mitigation of impacts to upstream and downstream fish passage. This paper descries three components of that effort: (1) a survey of environmental mitigation measures at hydropower sites across the country; (2) a critical review of the effectiveness of fish passage mitigation measures at 16 case study sites; and (3) ongoing efforts to develop new turbine designs that minimize turbine-passage mortality

    Hydroelectricity will continue to be important for meeting power requirements in developing countries. Much of the funding required for hydroelectric projects must come from non-government source; hydroelectric projects will therefore need to be attractive to private investors. This note explores the risks investors face, how this can be mitigated, and how the World Bank group can offer advice (as well as finance) to member countries to facilitate investment in hydro electric projects. 3 refs., 1 fig

    This paper describes and evaluates the environmental impacts of the Kayraktepe Dam and Hydroelectric Power Plant in Turkey. The contingent valuation method is used to estimate the project's local environmental costs. The average local rural annual willingness to pay for the restoration of the environmental impacts of the project is found to be USD 300 person -1 . Loss of forestry and agricultural benefits from the reservoir area that will be inundated are estimated to be USD 12.66 mill. yr -1 . When the Kayraktepe Project's external costs are internalized, its benefit cost ratio falls from 1.35 to 0.84, indicating that the project is economically undesirable and the decision for its construction needs to be reconsidered 26 refs, 1 fig, 5 tabs

  1. Feasibility determination of low head hydroelectric power development at existing sites: Mousam River Project

    Energy Technology Data Exchange (ETDEWEB)

    1979-06-01

    The technical and economic feasibility of low head hydroelectric power development at existing sites along the Mousam River in southeastern Maine was studied. The following areas were investigated: determination of available energy; development of restoration concepts; environmental studies; historical and archeological studies; assessment of civil construction requirements; geotechnical and geologic assessment of existing dams; assessment of turbine alternatives; assessment of generator and utility interface alternatives; economic analysis; and restoration concept evaluation and selection. The results of the hydropower evaluation showed that: of the seven sites evaluated, only four can be considered economically feasible for refurbishment at this time; the use of used and/or rebuilt equipment is more economically attractive than new equipment; the cost of equipment at each site was of the same order as the cost of the dam reconstruction; and the cost of fuel prices will be the determining feature of whether the sites should be reconstructed.

    1998-07-01

    The BAKUN Hydroelectric Power Project in Malaysia represents, alongside the Three Gorges Project in China, one of today's most closely observed hydropower projects. The Bakun Project features a generating capacity of 2 520 MW, a 205 m high concrete face rockfill dam and a 1 320 km long power transmission system from Sarawak (Borneo) to West Malaysia. Implementation costs are estimated at around DM 10 000 million. In December 1996 the concession to construct and operate the Bakun Project for a period of 30 years on a BOT (build-operate-transfer) basis was granted to the Bakun Hydro-Electric Corporation, a private project development company. A US-Dollar million contract was awarded one year prior to this concession, to construct the river diversion works in advance. Completion of the three concrete-lined diversion tunnels, each with an inner diameter of 12 m, is scheduled for the end of 1998. After a brief overview of the Bakun Project, the paper describes a typical structure of the parties involved and the legal framework for BOT project finance. The most important features of the concession agreement, the power purchase agreement (PPA) and the engineering, procurement and construction (EPC) contract are explained. Finally, the paper emphasizes that in future the water resources engineer will have to be more involved with topics such as fixed-price contracts, risk management, turnkey solutions and project finance.

    Full Text Available Forest plantations are considered the main carbon sinks thought to reduce the impact of climate change. Regarding many species, however, there is a lack of information in order to establish metrics on accumulation of biomass and carbon, principally due to the level of difficulty and the cost of quantification through direct measurement and destructive sampling. In this research, it was evaluated carbon stocks of forest plantations near the dam of hydroelectric project Cachí, which belongs to Instituto Costarricense de Electricidad. 25 unit samples were evaluated along some plantations that contain three different species. 30 Pinus caribacea trees, 14 Cupressus lusitanica and 15 Eucalyptus deglupta were extracted. The biomass was quantified by means of the destructive method. First of all, every component of the tree was weighed separately; then, sampling was obtained in order to determine the dry matter and the carbon fraction. 110 biomass samples from the three species were analyzed in laboratory, including all the components (leaves, branches, shaft, and root. The carbon fraction varied between 47,5 and 48,0 for Pinus caribacea; between 32,6 and 52,7 for Cupressus lusitanica, and beween 36,4 and 50,3% for Eucalyptus deglupta. The stored carbon was 230, 123, and 69 Mg ha-1 in plantations of P. caribaea, C. lusitanica and E. deglupta, respectively. Approximately, 75% of the stored carbon was detected in the shaft.

    A coalition of the Oregon wildlife agencies and tribes (the Oregon Wildlife Mitigation Coalition) have forged a cooperative effort to promote wildlife mitigation from losses to Oregon wildlife resources associated with the four mainstream Columbia River and the eight Willamette River Basin hydroelectric projects. This coalition formed a Joint Advisory Committee, made up of technical representatives from all of the tribes and agencies, to develop this report. The goal was to create a list of potential mitigation opportunities by priority, and to attempt to determine the costs of mitigating the wildlife losses. The information and analysis was completed for all projects in Oregon, but was gathered separately for the Lower Columbia and Willamette Basin projects. The coalition developed a procedure to gather information on potential mitigation projects and opportunities. All tribes, agencies and interested parties were contacted in an attempt to evaluate all proposed or potential mitigation. A database was developed and minimum criteria were established for opportunities to be considered. These criteria included the location of the mitigation site within a defined area, as well as other criteria established by the Northwest Power Planning Council. Costs were established for general habitats within the mitigation area, based on estimates from certified appraisers. An analysis of the cost effectiveness of various types of mitigation projects was completed. Estimates of operation and maintenance costs were also developed. The report outlines strategies for gathering mitigation potentials, evaluating them, determining their costs, and attempting to move towards their implementation.

BBNC’s technical contact and the project manager for this study was Douglas Vaught, P.E., of V3 Energy, LLC, in Eagle River, Alaska. The Bristol Bay region of Alaska is comprised of 29 communities ranging in size from the hub community of Dillingham with a population of approximately 3,000 people, to a few Native Alaska villages that have a few tens of residents. Communities chosen for inclusion in this project were Dillingham, Naknek, Togiak, New Stuyahok, Kokhanok, Perryville, Clark’s Point, and Koliganek. Selection criteria for conduction of wind resource assessments in these communities included population and commercial activity, utility interest, predicted Class 3 or better wind resource, absence of other sources of renewable energy, and geographical coverage of the region. Beginning with the first meteorological tower installation in October 2003, wind resource studies were completed at all sites with at least one year, and as much as two and a half years, of data. In general, the study results are very promising for wind power development in the region with Class 6 winds measured in Kokhanok; Class 4 winds in New Stuyahok, Clark’s Point, and Koliganek; Class 3 winds in Dillingham, Naknek, and Togiak; and Class 2 winds in Perryville. Measured annual average wind speeds and wind power densities at the 30 meter level varied from a high of 7.87 meters per second and 702 watts per square meter in Kokhanok (Class 6 winds), to a low of 4.60 meters per second and 185 watts per square meter in Perryville (Class 2 winds).

    The objectives of this studies were to determine i) if there was any potential health risks in terms of spread of vector-borne and other communicable diseases resulting from the changes in the environment due to creation of large bodies of water as consequence of the construction of dams, ii) diseases of public health importance in populations affected by such projects. Nine pre-impoundment studies had been carried out and potential impact of the change in environment on discases and health of the affected populations in each areas was evaluated. Risk of infections to the dam construction workers also assessed. Recommendations on mitigation measures were made for each situation so that adequate provisions could be made to improve the health conditions of these populations especially those who would be resettled as a result of impoundment . Prevention and control measures on transmission of infection, including vector control were proposed. The potential medico-ecological hazards encountered by immigrants and visitors to the area on completion of the hydro project were also envisaged.

    2009-01-01

    Task 18 working group of the International Energy Agency's Hydrogen Implementing Agreement has been evaluating and documenting experiences with renewable based hydrogen energy projects in remote and island communities in the United Kingdom, Canada, Norway, Iceland, Gran Canaria, Spain and New Zealand. The objective was to examine the lessons learned from existing projects and provide recommendations regarding the effective development of hydrogen systems. In order to accomplish this task, some of the drivers behind the niche markets where hydrogen systems have already been developed, or are in the development stages, were studied in order to determine how these could be expanded and modified to reach new markets. Renewable based hydrogen energy projects for remote and island communities are currently a key niche market. This paper compared various aspects of these projects and discussed the benefits, objectives and barriers facing the development of a hydrogen-based economy

    2010-01-01

    The Societe d'energie riviere Sheldrake Inc. (SERS Inc.) is planning to exploit the hydroelectric potential of the Sheldrake River in the Quebec municipality of Riviere au Tonnere. The proposed project will involve building a hydroelectric power station with a maximum capacity of 25 MW on the Sheldrake River, in the Courbe du Sault section. The project will also comprise a dam, a water reservoir and an overflow spillway. The project meets the province's 2006-2015 energy strategy to develop small-scale hydroelectric facilities. The project was subject to an environmental assessment as required by the province of Quebec. This environmental analysis addressed the major challenges facing the hydroelectric development at the Courbe du Sault section of the River, notably the impact on fish habitat, wetlands and the local and regional economic benefits. The environmental assessment did not indicate any habitat destruction for trout or salmon in the forebay. The Quebec Ministry of Sustainable Development, Environment and Parks has deemed the project to be acceptable given that certain conditions are met, including thresholds to stabilize the water level and the construction of a downstream fish passage facility to allow for safe fish migration. 22 refs., 2 tabs., 5 figs., 3 appendices.

    2013-06-01

    We assessed risk factors for vectors of dengue and chikungunya viruses near a new hydroelectric project, Nam Theun 2, in Laos. Immature stages of Aedes aegypti were found only in sites within 40 km of the urban provincial capital, but Aedes albopictus was found throughout. Aedes aegypti pupae were most common in water storage jars (odds ratio [OR] = 4.72) and tires (OR = 2.99), and Ae. albopictus pupae were associated with tires in 2009 (OR = 10.87) and drums, tires, and jars in 2010 (drums OR = 3.05; tires OR = 3.45, jars OR = 6.59). Compared with water storage vessels, containers used for hygiene, cooking, and drinking were 80% less likely to harbor Ae. albopictus pupae in 2010 (OR = 0.20), and discarded waste was associated with a 3.64 increased odds of infestation. Vector control efforts should focus on source reduction of water storage containers, particularly concrete jars and tires.

  7. Hydroelectricity and sustainable development

    International Nuclear Information System (INIS)

    Dubeau, D.

    1995-01-01

    From 1975 to 1992, hydroelectricity helped reduce greenhouse gas emissions in Quebec by 20%. For Hydro-Quebec, energy conservation and hydroelectric development are basic complementary tools for sustainable development. Recent studies show that developing only 50% of economically exploitable hydroelectric potential (30% of the gross theoretical potential) of different regions worldwide would considerably reduce greenhouse gas and SO 2 emissions. However, hydroelectric systems produce environmental and social impacts locally that require mitigative measures. To fulfill its mandate in a sustainable development context, Hydro-Quebec has adopted methods such as integrated resource planning, the assessment of externalities, multi criteria decision tools and public participations

    1995-01-01

    The Republic of the Marshall Islands has 60 dispensary sites, each staffed by 1 health assistant, to cover 80-800 people/site on 34 atolls. Until the spring of 1994, only curative services were available on a regular basis, and preventive services were provided by traveling health teams from the urban centers. In 1994, the health assistants in selected outer islands were trained to administer immunizations from vaccines which are sent regularly by air. Additional project sites are being selected. In 1993, 2 dispensaries initiated a project to 1) increase the number of women with access to prenatal care during the first trimester, 2) increase immunization levels, 3) improve access to preventive services, and 4) improve reporting and record-keeping systems. This project includes an important training component for the health assistant, the wife of the health assistant, the traditional birth attendant, the youth peer educator, community leaders, and a member of the local council. By 1994, this project was expanded to 13 dispensaries on 2 atolls. In 1995, 18 more dispensaries on 4 more atolls will be able to offer these additional services.

  15. Eradicating the tsetse fly on Zanzibar Island: A model project

    International Nuclear Information System (INIS)

    2003-01-01

    Tsetse flies infest vast areas of Africa and transmit a parasitic disease which devastates livestock herds and spreads debilitating 'sleeping sickness' amongst people. Past efforts to control the disease - Trypanosomosis - and the carrier insects have met with only limited success. But now an environmentally friendly technology called the Sterile Insect Technique (SIT) may provide a lasting solution to this scourge. Working with the Tanzanian Government and Zanzibar authorities, the Department of Technical Co-operation has sponsored a 'Model Project', with technical support from the Joint FAO/IAEA Division, to eradicate the tsetse fly completely from Zanzibar Island by applying SIT.

    Clarke, K.

    2009-01-01

    This report evaluated an environmental impact statement (EIS) submitted by a company proposing to develop a hydroelectric generation project in the lower Churchill River in Labrador. Construction of the facilities will alter the aquatic environment of the river as well as the receiving environment of lakes. The alterations are expected to have an impact on fish and fish habitats. The study evaluated the methods used to describe and predict impacts in the aquatic environment and examined models used for predictions in order to assess uncertainty levels. Results of the evaluation demonstrated that additional efforts are needed to document local knowledge of fish use and fish habitat, and that the magnitude of expected changes to fish habitat must be considered relative to the loss of fish habitat. The study also highlighted areas within the EIS that will require further clarification. A number of the studies used in the EIS had small sample sizes that increased the uncertainty of predictions made using the data. Uncertainties related to potential changes in flushing rates and morphological features was also needed. The impact of direct fish mortality from turbine operations was not addressed in a population context, and further information is needed to evaluate potential project-related effects on a species-by-species basis. 3 refs., 4 tabs.

    1990-01-01

    This paper reports on the problems that hydroelectric plants have regarding fish populations. The utilities that operate these plants are finding that accommodating migrating fish presents unique engineering challenges, not the least of which involves designing and building systems to protect fish species whose migratory behavior remains something of a mystery. Where such systems cannot be built, the status of hydroelectric dams may be in doubt, as is now the case with several dams in the United States. A further twist in some regions in the possibility that certain migratory fish will be declared threatened or endangered-a development that could wreak havoc on the hydroelectric energy supply in those regions

    Small Hydroelectric Engineering Practice is a comprehensive reference book covering all aspects of identifying, building, and operating hydroelectric schemes between 500 kW and 50 MW. In this range of outputs there are many options for all aspects of the scheme and it is very important that the best options are chosen.As small hydroelectric schemes are usually built against a limited budget it is extremely important that the concept design is optimum and every component is designed to maximise the benefi t and minimise the cost. As operating costs are often a high proportion of the income it i

    Mega hydropower projects in tropical forests pose a major emergent threat to terrestrial and freshwater biodiversity worldwide. Despite the unprecedented number of existing, under-construction and planned hydroelectric dams in lowland tropical forests, long-term effects on biodiversity have yet to be evaluated. We examine how medium and large-bodied assemblages of terrestrial and arboreal vertebrates (including 35 mammal, bird and tortoise species) responded to the drastic 26-year post-isolation history of archipelagic alteration in landscape structure and habitat quality in a major hydroelectric reservoir of Central Amazonia. The Balbina Hydroelectric Dam inundated 3,129 km2 of primary forests, simultaneously isolating 3,546 land-bridge islands. We conducted intensive biodiversity surveys at 37 of those islands and three adjacent continuous forests using a combination of four survey techniques, and detected strong forest habitat area effects in explaining patterns of vertebrate extinction. Beyond clear area effects, edge-mediated surface fire disturbance was the most important additional driver of species loss, particularly in islands smaller than 10 ha. Based on species-area models, we predict that only 0.7% of all islands now harbor a species-rich vertebrate assemblage consisting of ≥80% of all species. We highlight the colossal erosion in vertebrate diversity driven by a man-made dam and show that the biodiversity impacts of mega dams in lowland tropical forest regions have been severely overlooked. The geopolitical strategy to deploy many more large hydropower infrastructure projects in regions like lowland Amazonia should be urgently reassessed, and we strongly advise that long-term biodiversity impacts should be explicitly included in pre-approval environmental impact assessments.

  13. Battle looms over hydroelectric dam relicensing

    International Nuclear Information System (INIS)

    Simpson, J.

    1993-01-01

    Environmental groups, buoyed by support from influential lawmakers, are vowing to change the Federal Energy Regulatory Commission's (FERC's) hydroelectric relicensing procedures. For too long, the groups say, the hydroelectric industry has benefitted from a cozy relationship with the FERC, which has emphasized economic over environmental considerations. The success or failure of the environmentalists agenda will likely prove critical to the hydroelectric industry. With 237 hydroelectric licenses up for renewal this year - the most ever considered by the FERC in one year - and four vacant seats at the Commission, FERC hydro policy appears poised for upheaval. The groups have proposed a multipoint program to address perceived shortcomings in the FERC's hydroelectric relicensing procedures. The program includes recommendations to: Shorten dam licenses (which currently stretch 30 to 50 years) and require the FERC to periodically reevaluate the terms of hydropower licenses; Increase Congressional oversight of the FERC to assure adherence to environmental laws, including the National Environmental Policy Act, which mandates the preparation of environmental impact statements where appropriate; Mandate facilities for upstream and downstream fish passage; Establish a mitigation fund, collectable from dam owners, for river conservation and restoration programs; Promote all alternatives to relicensing projects, including denial of project licenses; and Reassign the FERC's hydropower jurisdiction to another federal agency, such as the Environmental Protection Agency or the Department of the Interior

  14. Emissions from hydroelectric reservoirs and comparison of hydroelectricity, natural gas and oil

    International Nuclear Information System (INIS)

    Gagnon, L.; Chamberland, A.

    1993-01-01

    When reservoirs are created, a small fraction of the flooded organic matter decomposes into humic acids, carbon dioxide (CO 2 ), methane (CH 4 ), nitrogen, phosphorus, and other elements. The major greenhouse gases produced are CO 2 and CH 4 . For northern projects, Canadian studies on emissions from hydroelectric reservoirs have reached similar conclusions: Emissions, including methane, are less than 35 kg CO 2 equivalent per MWh. Using a typical project in northern Quebec as the basis for analysis, none of the studies dispute the considerable advantages of hydroelectricity regarding greenhouse gas emissions. Taking into account all components of energy systems, emissions of greenhouse gases from natural-gas power plants are 24 to 26 times greater than emissions from hydroelectric plants. The Freshwater Institute, in an article published in Ambio suggests that emissions from hydroelectric plants could be a significant source of greenhouse gases. This conclusion does not apply to most hydroelectric projects for two reasons: First, the Freshwater Institute's studies concerned flooded peatlands and shallow reservoirs that are not typical of most hydro projects; and second, the Institute analyzed a hydro project with a ratio of flooded area to energy production that is 6 to 10 times higher than typical projects in Canada. 7 refs, 4 tabs

  15. The first cut-off wall in the Indian Himalayas for the dam of the Dhauliganga hydroelectric project

    Energy Technology Data Exchange (ETDEWEB)

    Brunner, W.G. [Bauer Maschinen GmbH, Berlin (Germany)

    2006-07-01

    This paper provided details a Bauer cutter used to build a cut-off wall for the Dhaulinganga power plant project in the Himalayan mountains. The dam for the project was built as a 56 m high concrete-faced rockfill dam with a length of 270 m at the crown. A cut-off wall was constructed on the upstream side of the dam extending down from the dam's plinth to the bedrock level. A Bauer cutter was used to key the cut-off wall straight into the bedrock, which omitted the need for a grout curtain. The cut-off wall is 1 m thick and 70 m deep, with a total area of 8000 m{sup 2}. The wall was constructed as a series of primary and secondary panels. Excavation of the panels was carried out in single bites by the Bauer DHG hydraulic diaphragm wall grabs, supported a box chisel, cross chisel and a Bauer BC 40 rock cutter. Trench stability was provided by bentonite slurry. The closing forces were activated by a cylinder which was installed vertically inside the base body. The Bauer cutter continuously removed soil and rock from the bottom of the trench for mixing with the bentonite slurry. The slurry was then pumped through a ring main of hose pipes to a desanding plant where it was cleaned and returned to the trench. Advantages offered by using the cutter included a consistently high output, an extremely high degree of verticality, watertight joints, and the ability to cut through hard boulders. Use of the cutter at the Dhaulinganga site showed that the project could not be carried out successfully without the use of the cutter, which was used whenever grab and chisel methods were unable to achieve satisfactory rates of penetration. Deployment of the cutter was essential to key the cut-off wall into the underlying bedrock. It was concluded that the Dhualinganga project will provide a model for future power generation projects in the Indian Himalayas. 11 figs.

    1997-01-01

    A lake of some 1784 sq km, consisting mostly of savanna vegetation, riverine forest, tropical dry forest and agricultural land, will be created by the construction of the Serra de Mesa hydroelectric reservoir in central Brazil. The lake will contain about 300 islands of various sizes. RADARSAT imagery and LANDSAT TM data is being used to analyze and assess the representativeness of the island and lake edge habitats in relation to the original mix of habitats prior to the flooding. The LANDSAT TM data will provide complementarity, with RADARSAT coverage showing the relief and TM coverage documenting the vegetation classes. In the next phase of the project field data on the biological communities of the islands will be correlated with the landscape classification by remote sensing

  6. Fish screens at hydroelectric diversions

    International Nuclear Information System (INIS)

    Ott, R.F.

    1994-01-01

    Preventing downstream migrating fish from entering the turbines at hydroelectric projects is a standard mitigation goal of state and federal fishery management agencies. The object is to minimize the adverse impacts to the fish associated with the exclusion and passage through the bypass water conveyance facilities. In the western United States, most of the fishery management agencies have fish screen design criteria that focus on the approach and transportational velocities, maximum opening dimensions of the screen material, and the cleaning standards. Recently, more attention has been given to fish behavioral traits such as attraction and sustained and darting swimming speed, which has resulted in more attention to the position of the screens to the flow and the length of time the downstream migrants are exposed to the screens. Criteria for length of time of exposure, size and position of bypass, flow and velocities in the bypass entrances, discharge requirements back into the receiving water, and exposure to predation have created unique challenges to the fish screen designer. This paper discusses some of the more recent types of fixed fish screens that are being installed at hydroelectric plants that meet these challenges

    Geophysical investigation using two dimensional electrical resistivity tomography (2D-ERT) method plays a significant role in determining the subsurface resistivity distribution by making measurement on the ground surface. This method was carried out at Dudhkoshi-II (230 MW) Hydroelectric Project, lies on Lesser Himalayan region of the Eastern Nepal to delineate the nature of the subsurface geology to assess its suitability for the construction of dam, desanding basin and powerhouse. The main objective of the proposed study consists of mapping vertical as well as horizontal variations of electrical resistivity to enable detection of the boundaries between unconsolidated materials and rocks of the different resistivity, possible geologic structures, such as possible presence of faults, fractures, and voids in intake and powerhouse area. For this purpose, the (WDJD-4 Multi-function Digital DC Resistivity/IP) equipment was used with Wenner array (60 electrodes). To fulfill these objectives of the study, the site area was mapped by Nine ERT profiles with different profile length and space between electrodes was 5 m. The depth of the investigation was 50 m. The acquired data were inverted to tomogram sections using tomographic inversion with RES2DINV commercial software. The Tomography sections show that the subsurface is classified into distinct geo-electric layers of dry unconsolidated overburden, saturated overburden, fractured rock and fresh bedrock of phyllites with quartzite and gneiss with different resistivity values. There were no voids and faults in the study area. Thickness of overburden at different region found to be different. Most of the survey area has bedrock of phyllites with quartzite; gneiss is also present in some location at intake area. Bedrock is found at the varies depth of 5-8 m at dam axis, 20-32 m at desanding basin and 3-10 m at powerhouse area. These results are confirmed and verified by using several boreholes data were drilled on the

    Demers, C. [Hydro-Quebec, Montreal, PQ (Canada)

    2003-12-01

    Power generation in Canada is a provincial responsibility. Since Quebec does not possess petroleum, natural gas or coal deposits, the Quebec government decided, in the 1970s, to develop hydroelectric resources in the northern regions of the province. This paper presents a brief historical overview of the hydroelectric development of the La Grande River project, also referred to as the James Bay project. Located approximately 1000 kilometres north of Montreal, the La Grande project lies in a humid continental climate with an average winter temperature of - 23 Celsius and an average summer temperature of 14 Celsius. The construction of the dam was not preceded by an environmental impact assessment, but environmental data was collected for the first time before construction began. It was an opportunity for all environmental sciences to develop inventory methodologies and analysis techniques specific to northern regions applicable to hydroelectric development. This project also required the signing of the James Bay and Northern Quebec Agreement by the governments of Canada and Quebec, Hydro-Quebec, and the Crees and Inuit of Quebec. The Agreement covers an area of 1 million square kilometres. As a result, Hydro-Quebec has become, over the past 30 years, a leader in environmental assessments and studies in the province. In northern Quebec, a hydroelectric reservoir constitutes an ecosystem whose biological productivity is comparable to a natural lake or ecosystem of equal area. During the first 5 years after flooding, reservoirs possess water quality slightly below that of a natural lake, but still favorable to biological development. The flooding of areas and the subsequent organic degradation promote mercury methylation and its accumulation in the food chain. The emissions of greenhouse gases by northern reservoirs are minimal compared to tropical reservoirs. The fauna in northern Quebec suffered habitat loss, but none became endangered.

    Electrical energy consumption in Brazil is increasing and new hydroelectric power stations are required. This work was carried out at a semi deciduous tropical island forest in Guaraciaba, MG to look for composition peculiarities and to provide a structural model which could be applied to reduce environmental damages caused by Pilar HPS. The point-centered quarter method was applied totalizing 50 sample units. Fifty five species were sampled and a Shannon diversity index (H) of 3.429 nats/individual found. The most important species were longiracemosus, Tapirira guianensis, Pera glabrata, Copaifera langsdorffii, Callophyllum brasiliensis and Guapira opposita. The Guaraciaba island forest presented the peculiarity of Podocarpus sellowii occurrence sellowii occurrence, a rare gymnosperm species that does not occur at nearby forests. The Guaraciaba island forest is probably representative of an original alluvial forest at Piranga valley. (author) 14 refs., 1 fig., 1 tab.

    Changes in Arctic coastal ecosystems in response to global warming may be some of the most severe on the planet. A better understanding and analysis of the rates at which these changes are expected to occur over the coming decades is crucial in order to delineate high-priority areas that are likely to be affected by climate changes. In this study we investigate the likelihood of changes to habitat-supporting barrier island – lagoon systems in response to projected changes in atmospheric and oceanographic forcing associated with Arctic warming. To better understand the relative importance of processes responsible for the current and future coastal landscape, key parameters related to increasing arctic temperatures are investigated and used to establish boundary conditions for models that simulate barrier island migration and inundation of deltaic deposits and low-lying tundra. The modeling effort investigates the dominance and relative importance of physical processes shaping the modern Arctic coastline as well as decadal responses due to projected conditions out to the year 2100.

    This report describes in details the project of the installation of a small-scale hydroelectric power plant on the river Areuse in Switzerland. Located on a 4 m high waterfall the plant includes a 10-13 m{sup 3}/s Kaplan turbine, which should deliver roughly 1.6 GWh/year for an installed power of about 500 kVA. The authors insist on the ecological aspect of the project. The plant will be built underground; the river track will be practically unchanged and the existing fish ladder maintained. The report includes maps and pictures of the site as well as technical drawings of the installation. An economic analysis of the project is presented and its viability is discussed. Finally, the authors state that the energy produced by this plant will certainly be certified under one of the Swiss labels 'naturemade star' or 'naturemade basic', in the framework of the federal government's promotion of renewable energy sources.

    A reconnaissance radiometric and stream sediment survey was conducted in Negros Island from April to May 1980. An area in Mabinay, Negros Oriental with significant above-background uranium in stream sediment was delineated in Upper Miocene to Pliocene continental clastic associated with silty limestone. In general, Negros has low radioactivity except for isolated points which have 2-3 times above-the-background radioactivity. Other areas in the western part of the island with high radioactivity and above-normal uranium in stream sediments were delineated. However, these above-normal observations were noted in areas underlain by recent volcanic sediments which were probably derived from Mt. Kanlaon. (author)

    The U.S. Geological Survey (USGS) and the Washington Department of Fish and Wildlife (WDFW) have been working with the Public Utility District No. 2 of Grant County, Washington (Grant PUD), to increase their understanding of predator-prey interactions in the Priest Rapids Hydroelectric Project (PRP), Columbia River, Washington. For this study, the PRP is defined as the area approximately 6 kilometers upstream of Wanapum Dam to the Priest Rapids Dam tailrace, 397.1 miles from the mouth of the Columbia River. Past year’s low survival numbers of juvenile steelhead (Oncorhynchus mykiss) through Wanapum and Priest Rapids Dams has prompted Grant PUD, on behalf of the Priest Rapids Coordinating Committee, to focus research efforts on steelhead migration and potential causal mechanisms for low survival. Steelhead passage survival in 2009 was estimated at 0.944 through the Wanapum Development (dam and reservoir) and 0.881 through the Priest Rapids Development and for 2010, steelhead survival was 0.855 for Wanapum Development and 0.904 for Priest Rapids Development. The USGS and WDFW implemented field collection efforts in 2011 for northern pikeminnow (Ptychocheilus oregonensis), smallmouth bass (Micropterus dolomieu), and walleye (Sander vitreus, formerly Stizostedion vitreum) and their diets in the PRP. For predator indexing, we collected 948 northern pikeminnow, 237 smallmouth bass, 18 walleye, and two largemouth bass (Micropterus salmoides). The intent of this study was to provide standardized predation indices within individual reaches of the PRP to discern spatial variability in predation patterns. Furthermore, the results of the 2011 study were compared to results of a concurrent steelhead survival study. Our results do not indicate excessively high predation of Oncorhynchus spp. occurring by northern pikeminnow or smallmouth bass in any particular reach throughout the study area. Although we found Oncorhynchus spp. in the predator diets, the relative

    As the global first AP1000 nuclear project, Sanmen phase I nuclear project itself has many challenges from design, procurement to construction managements for non practical nuclear project and experience can be referenced. Islands contract pattern was adopted by this project and this contract pattern has its own strength and weakness. Considering the negative influence result from the first unit, this project has the great postpone risk. Shadow management here tries to reduce these risks and enhance the project surveillance and control by the owner to promote the final goal of this project. (authors)

  19. Hydroelectricity, an opportunity to grab?

    International Nuclear Information System (INIS)

    Yergeau, M.

    1997-01-01

    The deregulation within the electricity sector and the government''s project approval process were discussed. Deregulation was meant to simplify trade while providing consumers with a fair price, quality service and end-product quality. Proposals for large hydroelectric projects, however, must still be authorized by the government. The environmental assessment process for projects involving energy transmission infrastructures is long and complicated. All of Hydro-Quebec''s recent large projects were challenged in court. While energy market players need environmentally credible generating schemes, there appears to be nothing on the horizon to suggest that the approval process is going to be made easier soon. Indeed, there is every reason to believe that recent gains in environmental and social protection will not be sold off to ease the burden on utility companies to prove their case before construction. The choice is between speed and quality in matters of authorization, and while every effort should be made to combine the two, when it comes down to a choice, there should be no question as to what must be preserved. 2 figs

  12. Air pollution prevention through urban heat island mitigation: An update on the urban heat island pilot project

    Energy Technology Data Exchange (ETDEWEB)

    Gorsevski, V.; Taha, H.; Quattrochi, D.; Luvall, J.

    1998-07-01

    Urban heat islands increase the demand for cooling energy and accelerate the formation of smog. They are created when natural vegetation is replaced by heat-absorbing surfaces such as building roofs and walls, parking lots, and streets. Through the implementation of measures designed to mitigate the urban heat island, communities can decrease their demand for energy and effectively cool the metropolitan landscape. In addition to the economic benefits, using less energy leads to reductions in emission of CO{sub 2}--a greenhouse gas--as well as ozone (smog) precursors such as NOx and VOCs. Because ozone is created when NOx and VOCs photochemically combine with heat and solar radiation, actions taken to lower ambient air temperature can significantly reduce ozone concentrations in certain areas. Measures to reverse the urban heat island include afforestation and the widespread use of highly reflective surfaces. To demonstrate the potential benefits of implementing these measures, EPA has teamed up with NASA and LBNL to initiate a pilot project with three US cities. As part of the pilot, NASA will use remotely-sensed data to quantify surface temperature, albedo, the thermal response number and NDVI vegetation of each city. This information will be used by scientists at Lawrence Berkeley National Laboratory (LBNL) along with other data as inputs to model various scenarios that will help quantify the potential benefits of urban heat island mitigation measures in terms of reduced energy use and pollution. This paper will briefly describe this pilot project and provide an update on the progress to date.

    In the Northeast region, the physical potential for all sites exceeds 33,000 MW of capacity with an estimated average annual energy of some 153,000 GWH. By comparison, the available data represent about 6% of the total capacity and 11% of the hydroelectric energy potential estimated for the entire US. Of the total capacity estimated for the region, 6100 MW has been installed. The remainder (27,200 MW, excluding the undeveloped capacity in the New England States) is the maximum which could be developed by upgrading and expanding existing projects (18,700 MW), and by installing new hydroelectric power capacity at all potentially feasible, undeveloped sites (8500 MW). Small-scale facilities account for about 15% of the region's total installed capacity, but another 1800 MW could be added to these and other small water-resource projects. In addition, 500 MW could be installed at potentially feasible, undeveloped small-scale sites. The small-scale resource varies considerably, with the states of New York, Maine, and New Hampshire having the largest potential for incremental development at existing projects in the Northeast region. West Virginia, Maryland, Delaware, New Jersey, Pennsylvania, New York, Connecticut, Massachusetts, Rhode Island, New Hampshire, Vermont, and Maine comprise the Northeast region.

When the foreseen contribution of our HE installed power to our total installed power and that of our HE energy production to our total energy production for 2005-2020 period is analysed, it is seen that it is foreseen that these contributions are not to be changing at significant levels for the coming 15 years. It has not been possible to explain the fact that 2/3 of our hydroelectric potential, which is independent of foreign countries, is not yet evaluated and the fact that no attempt is made to increase its contribution. This situation should be perceived as an unusual approach in our country.

    This report describes in details the project of the installation of a small-scale hydroelectric power plant on the river Areuse in Switzerland. Located on a 4 m high waterfall the plant includes a 10-13 m{sup 3}/s Kaplan turbine, which should deliver roughly 1.6 GWh/year for an installed power of about 500 kVA. The authors insist on the ecological aspect of the project. The plant will be built underground; the river track will be practically unchanged and the existing fish ladder maintained. The report includes maps and pictures of the site as well as technical drawings of the installation. An economic analysis of the project is presented and its viability is discussed. Finally, the authors state that the energy produced by this plant will certainly be certified under one of the Swiss labels 'naturemade star' or 'naturemade basic', in the framework of the federal government's promotion of renewable energy sources.

  5. Rhode Island crystalline repository project: Technical progress report, 1984-1986

    1986-01-01

    A Nuclear Waste Fund established by the Nuclear Waste Policy Act of 1982 provided financial support to the State of Rhode Island for its participation in the high-level radioactive waste repository siting program. In 1984, the Office of the Governor set up a multidisciplinary Project Review Team consisting of staff from three State agencies and the University of Rhode Island. Members of the Review Team attended several meetings throughout the reporting period to voice their concerns about siting directly to the US Department of Energy (DOE). Written comments were also submitted on draft plans and reports. Many of Rhode Island's recommendations in these comments were later adopted. In May, 1986, Secretary of Energy John Herrington announced the suspension of the crystalline repository siting program. The remainder of the year was spent monitoring litigation challenging that decision and pending legislation. Administrative phase-down of the program was essentially complete by the close of the calendar year

    This report presents the results of an environmental study carried out in the Qingua/Tunugliarfik Fiord area north of Narssarssuaq in July-October, 1982. The field work in the area included hydrographic investigations in the Tunugliarfik Fiord, fishery investigations in the Qingua river and a survey of the area likely to be affected by a hydro-electric plant. Information on commercial and sport fishing, hunting, sheep-farming, tourism, and conservation interests was also collected. The hydrographic investigations have shown that the inner part of Tunugliarfik is dominated by the estuarine circulation in the upper layer clearly influenced by the Qoroq Fiord. The lower 5 km of the river contain a large population of arctic char. The size of the migrating stock, i.e. excluding young and residual fish, is estimated at 10.000 - 20.000 fish. A series of waterfalls in the end of the Qingua valley constrains migrating fish to the lower river area. Beyond the falls two separate populations of stream-resident arctic char are found. Another non-migrant population is found in the Nordbo/Storesoe area. The arctic char fishery is locally of great importance. The fishery, which is carried out by use of gill net, is particularly extensive in the inner part of the Tunugliarfik Fiord. The Qiangua valley is also a popular site for anglers coming to the area by a daily boat from the hotel in Narssarssuaq. Besides char, great quantities of Greenland cod and Greenland halibut are caught in the fiord. The major part of the catch is consumed locally.

    Following the oil crises of 1973 and 1979, there was renewed and justifiable interest in small hydroelectric plants. The maximum power of these plants rarely exceeds 10 MW, and their development will surely increase in the coming decades. Hydraulic power is a national renewable resource, unaffected by geopolitical problems, and above all, non polluting. Many countries with their own hydraulic resources in both the industrialized and the developing world have expressed needs for the development of small hydroelectric plants. Hidroenergia 91 Conference is the opportunity to take stock of knowledge gained in the vast field of small hydroelectric plants. The meeting is divided into four subjects: 1 methods for decision aid; 2 environmental impact and accompanying answers; 3 national development policy; 4 world market and international cooperation. This meeting contains 75 papers, 8 papers are in the INIS scope and 72 papers are in the ENERGY DATA BASE scope

    Sequencing of microbial genomes is important because of microbial-carrying antibiotic and pathogenetic activities. However, even with the help of new assembling software, finishing a whole genome is a time-consuming task. In most bacteria, pathogenetic or antibiotic genes are carried in genomic islands. Therefore, a quick genomic island (GI) prediction method is useful for ongoing sequencing genomes. In this work, we built a Web server called GI-POP (http://gipop.life.nthu.edu.tw) which integrates a sequence assembling tool, a functional annotation pipeline, and a high-performance GI predicting module, in a support vector machine (SVM)-based method called genomic island genomic profile scanning (GI-GPS). The draft genomes of the ongoing genome projects in contigs or scaffolds can be submitted to our Web server, and it provides the functional annotation and highly probable GI-predicting results. GI-POP is a comprehensive annotation Web server designed for ongoing genome project analysis. Researchers can perform annotation and obtain pre-analytic information include possible GIs, coding/non-coding sequences and functional analysis from their draft genomes. This pre-analytic system can provide useful information for finishing a genome sequencing project. Copyright © 2012 Elsevier B.V. All rights reserved.

  14. Environmental consequences of hydroelectric development: the role of facility size and type

    1992-01-01

    The development of hydroelectric power throughout the world is receiving renewed attention as the economic, political, and environmental costs of conventional energy production rise. There is currently a perception that hydroelectricity has environmental and economic advantages over electricity produced by conventional energy technologies, but there is a paucity of information about the environmental impacts of hydroelectric facilities as a function of size and type. We characterize the environmental impacts of hydroelectric developments and quantify these impacts as a function of the size and type of project. Several unexpected conclusions arise from our analysis. For most hydroelectric facilities, size, as measured by installed capacity, is not necessarily a good indicator or the severity of environmental costs. For impacts such as land flooded and evaporative water lost, smaller facilities cause greater environmental disruptions per unit of energy produced than do larger facilities. (Author)

    In this chapter of the book author deals with the Gabcikovo-Nagymaros Project (GNP). The Gabcikovo part of the hydroelectric power project was based on a combination of flood control, navigational improvements and the production of electric energy. The Gabcikovo Project has not only saved the inundation area with the flood plain ecotopes, but also includes a wide variety of tools for surface and ground water management, and thus also for the management, or optimalization, of the development of agricultural conditions, inundation biotopes, forestry, river branches biotopes, flood management and the flooding of parts of the inundation area, sedimentation and erosion processes, ground and surface water quality, and other environmental effects management. The GNP, as conceived in the 1977 International Czechoslovak-Hungarian Treaty, is located roughly between 1,860 rkm (river kilometer), at Bratislava, and 1,696 rkm, at Nagymaros. The Hungarians unilaterally decided to abandon the construction of Nagyamaros, and to suspend the work to be carried out on the GNP. After the decision, in order to minimize the spread of economic and ecologic damages to ensure flood protection at least on the Hungarian Szikekoez, to exploit the available power potential, and to create conditions necessary for navigation on the Danube, the Government of the Czech and Slovak Federal Republic decided in December 1991, to put nearly ready Gabcikovo part of the system into operation, constructing the necessary technical structures on their own territory and inside of the construction area of the original Project. These technical structures are known as 'Variant C'. 'Variant C' is situated inside the area of the original project, replaces the function of the Dunakiliti weir in Hungary and uses all of the completed structures of the Gabcikovo part of the Project. The geology, Danube, ground water, pre-dam long-term development, changes after putting the Gabcikovo structures into operation, as well

    Basically this report gives a clear vision of the possibilities of energy development in the Colombian Atlantic Coast, projects that contemplate a wide range as soon as it refers that is to say to generation ranges, they have been identified at level macro in the Sierra Nevada region and the Peasant with a profitable hydroelectric potential of 631 MW; in the Sinu region, 3 projects were identified with a profitable potential of 1186 MW and in the Magdalena region, was also identified 3 projects whose profitable potential is of 475 MW. At level micro, the carried out studies defined in the same previous regions a series of projects that they necessarily reach the megawatt. The report contains a description of each one of the identified projects and its current situation. It also presents a review of the makers of turbines that exist at the moment in the country

    1993-06-01

    This pilot project comprises a feasibility study in connection with plans to establish a biomass conversion plant, on the Danish island of Mors, which would provide methane to be used as fuel, in combination with natural gas, for a cogeneration plant serving six villages. The subjects of location, organization, the transportation of biomass, the design of the biomass conversion plant, economical aspects and conditions of the use of the methane are discussed as a basis for decisions in this respect. Environmental considerations are also dealt with. (AB)

    The objective of this study was to provide an objective documentary source, relevant and usable for institutional and economic players at a regional colloquium on renewable energies which was to be organized by the French Polynesian community and the High Commission of the Republic in the second quarter of 2014. However, the date was put back due to local political changes which occurred following the last territorial elections (mid-2013). More largely, in the context of the fight against climate change, the subject of renewable energies takes on considerable importance. A large number of island States in the Pacific zone are extremely dependent on fossil fuels, and in the coming years, will face major impacts related to climate change (biodiversity, rising sea level, food security,...). It should be noted here that the small island countries (notably those of the Pacific) which belong to the intergovernmental organization AOSIS (Alliance of Small Island States), constitute a real lobbying force in the face of large industrialized countries at climate negotiations. Images of the Maldives' Council of Ministers meeting underwater demonstrate the will of small island States to make themselves heard at the highest levels. The notion of 'climate refugees' is not a mere idea; it could soon become a veritable legal concept. This study in no way claims to meet these challenges, but strives to highlight some solutions which are working ('good practices' in donors' terms), in order to propose adapting or replicating them. The accepted approach is thus above all positive and constructive: solutions exist, sometimes at low cost, and the projects help give Pacific peoples the feeling that they belong to wider global community, not to mention a sometimes small but important part of their harmony

  3. Which hydroelectric potential in your region?

    International Nuclear Information System (INIS)

    2011-01-01

    Illustrated by photos, maps, figures and graphs, this Power Point presentation outlines the important remaining potential of hydroelectricity in France: 10.6 TWh. It indicates how this potential has been assessed and calculated. Even if possibilities exist everywhere (either by building new dams or by exploiting existing weirs), four regions present a higher potential for new works: Rhone-Alpes, Midi-Pyrenees, Auvergne, and Provence-Alpes-Cote d'Azur. Maps indicate the concerned rivers and locations in some regions. Such projects which could boost economic local, regional and national development must be designed while taking planning tools into account (notably the climate-air-energy regional schemes), and rules related to river preservation

  4. Detailed Urban Heat Island Projections for Cities Worldwide: Dynamical Downscaling CMIP5 Global Climate Models

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available A new dynamical downscaling methodology to analyze the impact of global climate change on the local climate of cities worldwide is presented. The urban boundary layer climate model UrbClim is coupled to 11 global climate models contained in the Coupled Model Intercomparison Project 5 archive, conducting 20-year simulations for present (1986–2005 and future (2081–2100 climate conditions, considering the Representative Concentration Pathway 8.5 climate scenario. The evolution of the urban heat island of eight different cities, located on three continents, is quantified and assessed, with an unprecedented horizontal resolution of a few hundred meters. For all cities, urban and rural air temperatures are found to increase strongly, up to 7 °C. However, the urban heat island intensity in most cases increases only slightly, often even below the range of uncertainty. A potential explanation, focusing on the role of increased incoming longwave radiation, is put forth. Finally, an alternative method for generating urban climate projections is proposed, combining the ensemble temperature change statistics and the results of the present-day urban climate.

    The Arizona Sky Island Arthropod Project (ASAP) is a new multi-disciplinary research program at the University of Arizona that combines systematics, biogeography, ecology, and population genetics to study origins and patterns of arthropod diversity along elevation gradients and among mountain ranges in the Madrean Sky Island Region. Arthropods represent taxonomically and ecologically diverse organisms that drive key ecosystem processes in this mountain archipelago. Using data from museum specimens and specimens we obtain during long-term collecting and monitoring programs, ASAP will document arthropod species across Arizona's Sky Islands to address a number of fundamental questions about arthropods of this region. Baseline data will be used to determine climatic boundaries for target species, which will then be integrated with climatological models to predict future changes in arthropod communities and distributions in the wake of rapid climate change. ASAP also makes use of the natural laboratory provided by the Sky Islands to investigate ecological and genetic factors that influence diversification and patterns of community assembly. Here, we introduce the project, outline overarching goals, and describe preliminary data from the first year of sampling ground-dwelling beetles and ants in the Santa Catalina Mountains.

    Radioactive fallout from nuclear test detonations during 1946-1958 at Bikini and Enewetak Atolls in the Marshall Islands (MI) exposed populations living elsewhere in the MI archipelago. A comprehensive analysis, presented in seven companion papers, has produced estimates of tissue-specific radiation absorbed dose to MI residents at all historically inhabited atolls from internal (ingested) and external irradiation resulting from exposure to radioactive fallout, by calendar year, and by age of the population at time of exposure. The present report deals, for the first time, with the implications of these doses for cancer risk among exposed members of the MI population. Radiation doses differed by geographic location and year of birth, and radiation-related cancer risk depends upon age at exposure and age at observation for risk. Using dose-response models based on committee reports published by the National Research Council and the National Institutes of Health, we project that, during the lifetimes of members of the MI population potentially exposed to ionizing radiation from weapons test fallout deposited during the testing period (1948-1958) and from residual radioactive sources during the subsequent 12 y (1959-1970), perhaps 1.6% (with 90% uncertainty range 0.4% to 3.4%) of all cancers might be attributable to fallout-related radiation exposures. By sub-population, the projected proportion of cancers attributable to radiation from fallout from all nuclear tests conducted in the Marshall Islands is 55% (28% to 69%) among 82 persons exposed in 1954 on Rongelap and Ailinginae, 10% (2.4% to 22%) for 157 persons exposed on Utrik, and 2.2% (0.5% to 4.8%) and 0.8% (0.2% to 1.8%), respectively, for the much larger populations exposed in mid-latitude locations including Kwajalein and in southern locations including Majuro. By cancer type, point estimates of attributable risk varied, by location, between 12% and 95% for thyroid cancer, between 2% and 78% for leukemia, and

    2018-01-01

    Even if the Sein Island emits less CO 2 emissions than 700 vehicles, the Government set an objective of 50 per cent for renewable energy production within its multi-year energy planning (PPE). The objectives of the authors is herein to analyse the credibility of these PPE objectives, more particularly as far as electric power autonomy is concerned. They used available and precise data related to the island's energy consumption. They show that this 50 per cent coverage can indeed be reached, but with investments which are not justified when the population size and current resulting pollution are considered. They also outline that diesel engines will still be used from time to time, and that their emissions will not even be reduced as diesel units will not operate in optimal regime. Therefore, they regret that such objectives have been imposed to the island without any detailed preliminary study

    2006-01-01

    With the scope of showing and preserving an island endangered species, the Swanka turtle, a campaign and an environmental education program were conducted. The campaign consisted in showing the species to the community, its characteristics and its threats, through mass media and visits to different local schools. The environmental education program was carried out through a Scholar Environmental Project, which consisted on the conformation of an environmental group, where cognitive, attitudinal and participative aspects were worked together. Using a constrictive methodology the children developed some knowledge about the species and Its habitats. The scope was that they modified attitudes and behaviors towards situations that contribute to environmental damage; the reinforcement of values was the central point during all the activities. The knowledge gained by the pupils and the observed changes on their attitudes and participation show the positive results that arise when the action of environmental education focuses on the people and not the resources that are to be preserved

    A Nuclear Waste Fund established by the Nuclear Waste Policy Act of 1982 provides financial support to affected states to participate in the high-level radioactive waste repository siting program of the US Department of Energy. In Rhode Island, that function was performed by a multidisciplinary Project Review Team consisting of staff from three State agencies. Members of the Review Team attended several meetings in 1986 to discuss mutual concerns with Federal, State and Tribal officials. Comments were developed on DOE's Draft Area Recommendation Report. Members of the Review Team also testified at a public hearing in Providence on the Draft ARR, and developed and distributed a public information booklet. In May, Secretary of Energy John Herrington announced the suspension of the crystalline repository siting program. The remainder of the year was spent monitoring litigation challenging that decision and pending legislation. Administrative phase-down of the program was essentially complete by the close of the calendar year

In Rhode Island, that function is performed by a multidisciplinary Project Review Team consisting of staff from three State agencies. Members of the Review Team attended several meetings in 1985 to voice their concerns directly to DOE. Written comments were also submitted on draft plans and reports. Among the issues raised were inconsistencies in the geologic and environmental data used to screen potential repository sites, the role of Monitored Retrievable Storage (MRS) in the repository program, and regulations regarding the transportation and storage of nuclear waste. The Review Team also began work on a public information booklet describing the repository program in nontechnical terms. That booklet will be distributed widely upon completion

  14. Climate change and hydroelectric production

    1991-01-01

    Manitoba Hydro is planning for the possibility of climate change, which has the potential to adversely effect its hydroelectric generating potential. Theoretical and physical evidence for a global warming are reviewed, and it is shown that some of Manitoba Hydro's own measurements support a warming hypothesis. The most significant effect on the hydraulic generating system would be associated with diminished river flows. Winter hydraulic generation capability would be reduced if the magnitude of the change were sufficient to cause several freeze-ups and break-ups within a given season. Incidence of transmission line icing would probably increase, permafrost recession may undermine tower foundations, and conductor resistance may increase to increase energy loss. Ice crossings and winter roads would be adversely affected, and a restriction on fossil fuel consumption could limit thermal generation and increase demand for hydroelectric or nuclear energy. Manitoba Hydro is examining a number of no-cost or low-cost options to accomodate potential climate change, using probable maximum precipitation hydrologic technology, research into conductor galloping, line icing detection, and hydrological investigations

    This paper presents an analysis of the past and present situation in hydroelectric power (achievements, rates of commissioning and so on) and the future strategies for the hydroelectric power resource development in the conditions of a free market economy. At present the contribution of hydroelectric power in the Romania's total power balance is about 16,500 GW h/year which represents nearly 28 %. The theoretical hydroelectric power potential of Romania is 75,000 GW h/year while the technical potential, which could actually be developed, is only 40,000 GW h/year. Finally, there are presented the main directions in the hydroelectric power development up to the year 2020. (author) 3 tabs

    1980-05-01

    The legal and institutional obstacles to the development of small-scale hydroelectric energy at the state level are examined. The introductory section examines the dual regulatory system from the standpoint of the appropriate legal doctrine, the law of pre-emption, application of the law to the case of hydroelectric development, and concludes with an inquiry into the practical use of the doctrine by the FERC. Additional sections cover acquisition; liability; Department for Natural Resources and Environmental Protection; energy utilities; local regulations; incidental impacts; financial considerations; and sources of information. In Kentucky, many of the impacts have not been implemented with regard to small-scale hydroelectric energy, since in Kentucky most electricity is coal-generated and any hydroelectric power that does exist, is derived from TVA or the Army Corp of Engineer projects.

    Changes in future wave climates in the tropical Pacific Ocean from global climate change are not well understood. Spatially and temporally varying waves dominate coastal morphology and ecosystem structure of the islands throughout the tropical Pacific. Waves also impact coastal infrastructure, natural and cultural resources, and coastal-related economic activities of the islands. Wave heights, periods, and directions were forecast through the year 2100 using wind parameter outputs from four atmosphere-ocean global climate models from the Coupled Model Inter-Comparison Project, Phase 5, for Representative Concentration Pathways (RCP) scenarios 4.5 and 8.5 that correspond to moderately mitigated and unmitigated greenhouse gas emissions, respectively. Wind fields from the global climate models were used to drive a global WAVEWATCH-III wave model and generate hourly time-series of bulk wave parameters for 25 islands in the mid to western tropical Pacific for the years 1976–2005 (historical), 2026–2045 (mid-century projection), and 2085–2100 (end-of-century projection). Although the results show some spatial heterogeneity, overall the December-February extreme significant wave heights, defined as the mean of the top 5 percent of significant wave height time-series data modeled within a specific period, increase from present to mid-century and then decrease toward the end of the century; June-August extreme wave heights increase throughout the century within the Central region of the study area; and September-November wave heights decrease strongly throughout the 21st century, displaying the largest and most widespread decreases of any season. Peak wave periods increase east of the International Date Line during the December-February and June-August seasons under RCP4.5. Under the RCP8.5 scenario, wave periods decrease west of the International Date Line during December-February but increase in the eastern half of the study area. Otherwise, wave periods decrease

    2017-01-01

    This paper develops a geopolitical analysis of dams and hydroelectric plants in the Brazilian Amazon since the mid-2000's. The implementation of these projects has provoked tensions within the federal government under the presidency of the Workers' Party and accelerated the erosion of the ideological and political platform called 'socio-environmentalism', a situation that has led to the break-up of the coalition leading to the political crisis of 2016 and the impeachment of President Dilma Rousseff. From a regional point of view, the dispute occurred in very different terms in the case of the Madeira hydroelectric power stations (Santo Antonio and Jirau in Rondonia) and in the case of the Xingu dam (Belo Monte in Para), worldwide covered by the media

    Using a case-study, inductive, narrative approach, this article explores the history, drivers, benefits, and barriers to the Bakun Hydroelectric Project in East Malaysia. Situated on the island of Borneo, Bakun Dam is a 204 m high concrete face, rock filled dam on the Balui River in the Upper Rajang Basin in the rainforests of Sarawak. Bakun Dam and its affiliated infrastructure could be the single largest and most expensive energy project ever undertaken in Southeast Asia. Based on data collected through site visits, original field research in Sarawak, and more than 80 research interviews, the article begins by teasing out the complex history and drivers behind the Bakun project before identifying a set of potential social, political, and economic benefits the project could deliver. It then delves into six sets of barriers in the technical, economic, political, legal and regulatory, social, and environmental realms. We find that Bakun illustrates how centralized energy megaprojects, while ostensibly championed for reasons of economies of scale and the ability to bring about transformational change in the shortest period of time, often fail to address broader development goals such as fighting energy poverty and improving the livelihoods of the local communities they are supposed to serve. - Highlights: > Bakun Dam is concrete face, rock filled dam on the Balui River in the Upper Rajang Basin in the rainforests of Sarawak. > The project faces technical, economic, political, legal and regulatory, social, and environmental barriers. > We conclude the project will fail to fight energy poverty or improve the livelihoods of local populations.

    2010-09-15

    Hydroelectric developments built in the early 1900's are nearing their useful lifespan and require significant rehabilitation in order to meet modern safety and performance criteria. Also, global increasing energy costs represent a strong incentive for operators to find low-cost, environment-friendly solutions while increasing energy generation at existing facilities. Projects promoting innovative ways of recycling existing developments are great examples of sustainable development and represent win-win solutions for population and hydropower industry alike. The proposed presentation describes successful projects consisting in the rehabilitation or addition of power to existing hydroelectric. These recycling projects are very attractive from both economic and environmental.

The first part treats of the hydroelectric facilities and of the market of hydroelectric power plants. It presents the technology used and the different types of plants, the evolution of their geographical setting and the future potentialities of development. The second part deals with the competitiveness of this industry with respect to: the energy policy stakes, the profitability, the energy independence of countries, the regulation of power networks and the environmental impacts.

    Construction of a small hydroelectric power station provides additional amounts of electric energy, engages a private capital, revives investment activities and promotes the use of renewable energy sources. Transmission losses are reduced, a voltage of higher quality is achieved and idle power is compensated by the generation of electricity in the small hydroelectric power stations and at the place of consumption. Legislation and technical regulations, however, require a multidisciplinary approach, defining of complex spaces and environmental protection. Unfortunately, complete documents should be prepared for small,hydroelectric plants just as for big ones what is a long procedure and many of those papers are unnecessary or even superfluous.

  4. SITE-94, Biosphere Model for SKI Project on the island of Aspro

    International Nuclear Information System (INIS)

    Barrdahl, Runo Alfons Gunnar

    2003-01-01

    1 - Description of program or function: A simple biosphere model has been designed for use in the SKI project related to a hypothetical repository for spent nuclear fuel on the island of Aspro near Oskarshamn in Southern Sweden. Project SITE-94 studies the safety aspects of this hypothetical repository. Any weakness in repository performance will reveal itself as a leakage of radionuclides out of the repository, and finally into the biosphere where man and nature are at risk of being exposed. Thus, as the final link in estimating such leakage, a biosphere model will provide an estimate of resulting radiation impact on man and nature. 2 - Methods: The present biosphere model involves a stationary scenario (Reference Scenario) and a climate evolution and geological scenario (Central Scenario). The stationary and time evolution scenarios contain as primary recipients a well and the bay of Borholm, i.e., the waters surrounding the island of Aspo. The time evolution scenario additionally incorporates as primary recipients a waste sample from intrusion and, in a remote future time, the Baltic Sea. Transport of radionuclides within the model system is assumed to be essentially immediate, except for in sediment subject to land rise. Except for this pathway, radioactive decay is therefore not included at all in the model. Land rise sediment is modeled to be subject to radioactive decay from the time the sediment no longer constitutes sea bottom until the desired time point of the model. Correction for radioactive decay is thus generally supposed to be made outside the biosphere model. Unless otherwise indicated, yearly individual and population committed (50 years) radiation doses to man are considered, and all scenarios involve a constant flux of 1 Bq/y of each radionuclide considered into the respective primary recipient. Nominal values of radionuclide flux will finally be multiplied with the radiation dose per one Bq per year resulting from the model in order to obtain

    Hydro-electric energy offers considerable possibilities and advantages which should be exploited before considering the construction of power which use fossil fuels. In fact: - hydro-electric is the only renewable energy available in very large quantities at competitive prices, - there are still many possibilities for producing it since at present only 14% is exploited, - hydraulic machines have been considerably improved over recent years, - the improvements make it possible to use watercourses in successive stages thus considerably reducing damage to the environment, - hydro-electric installations have a regulating effect, - vast areas of uncultivated land can be irrigated using the water reserves created by the artificial lakes. All these reasons favour intensive exploitation of hydro-electric energy reserves, in spite of the initial investment costs, which are sometimes higher than those for constructing fuel/driven power stations.

    1994-01-01

    In a recent paper, Rudd et al. have suggested that, per unit of electrical energy produced, greenhouse-gas emissions from some hydroelectric reservoirs in northern Canada may be comparable to emissions from fossil-fuelled power plants. The purpose of this comment is to elaborate these issues further so as to understand the potential contribution of hydroelectric reservoirs to the greenhouse effect. More than focusing on the total budget of carbon emissions (be they in the form of CH 4 or be they in the form of CO 2 ), this requires an evaluation of the accumulated greenhouse effect of gas emissions from hydroelectric reservoirs and fossil-fuelled power plants. Two issues will be considered: (a) global warming potential (GWP) for CH 4 ; and (b) how greenhouse-gas emissions from hydroelectric power plants stand against emissions from fossil-fuelled power plants with respect to global warming

    This paper discusses the application of marginal cost concepts to the expansion planning of hydroelectric systems. It is shown that the renumeration of hydroelectric plants should not be based on their energy production, as this leads to excessive revenues for the plant owner, and distorts the dimensioning of upstream reservoirs. In order to produce the adequate economic signals, it is necessary to separate the contributions of turbines and reservoirs. Examples from the Brazilian power system are presented and discussed

    The new design of the turbine of hydroelectric power plant (HPP) is executed in the form of a pipe with plates. Proposed solution allows increasing the hydroelectric power plant capacity at existing head and water flow. At that time the HPP turbine reliability is increase, its operation performances are improving. Design efficiency is effective mostly for small-scale and micro-HPP due to reliable operation, low-end technology, and harmless ecological application. (author)

    Full Text Available Wave energy and storm surges threaten coastal ecology and nearshore infrastructures. Although coastal structures are conventionally constructed to dampen the wave energy, they introduce tremendous damage to the ecology of the coast. To minimize environmental impact, ecofriendly coastal protection schemes should be introduced. In this paper, we discuss an example of an innovative mangrove rehabilitation attempt to restore the endangered mangroves on Carey Island, Malaysia. A submerged detached breakwater system was constructed to dampen the energy of wave and trap the sediments behind the structure. Further, a large number of mangrove seedlings were planted using different techniques. Further, we assess the possibility of success for a future mangrove rehabilitation project at the site in the context of sedimentology, bathymetry, and hydrogeochemistry. The assessment showed an increase in the amount of silt and clay, and the seabed was noticeably elevated. The nutrient concentration, the pH value, and the salinity index demonstrate that the site is conducive in establishing mangrove seedlings. As a result, we conclude that the site is now ready for attempts to rehabilitate the lost mangrove forest.

    Construction was initiated following the 2000 tern breeding season for Phase 1 of a planned two-phase ?Shoreline Protection and Erosion Control Project? at the Falkner Island Unit of the USFWS Stewart B. McKinney National Wildlife Refuge located in Long Island Sound off the coast of Guilford, CT. When the Common Tern (Sterna hirundo) and federally endangered Roseate Tern (S. dougallii) arrived in spring 2001, they encountered several major habitat changes from what had existed in previous years. These changes included: a rock revetment covering most of the former nesting habitat on the beach from the northwestern section around the northern tip and covering about 60% of the eastern side; an elevated 60- ? 4-m shelf covering the beach and lower bank of the southwestern section; and about 2,000 sq m of devegetated areas on top of the island on the northeast side above the revetment, and about one-third of the southern half of the island. The southwest shelf was created by bulldozing and compacting extra construction fill and in situ materials. This shelf differed in internal structure from the main revetment on the north and eastern sections of the island because it lacked the deep internal crevices of the revetment. The deep internal crevices were created from the large stones and boulders (up to 2 tons) used in the construction of the main revetment. Small rock and gravel was used to fill the crevices to within 3 feet (0.9 m) of the surface of the revetment. Because half-buried tires and nest boxes for the six Roseate Tern (Sterna dougallii) sub-colony areas were deployed in similar patterns on the remaining beach, and nest boxes were placed on the newly elevated shelf areas several meters above previous locations on the now-covered beach areas, the distribution of Roseate Tern nests did not change much from 2000 to 2001. However, the movements of Roseate Tern chicks ? in many cases led by their parents towards traditional hiding places ? into the labyrinth of

  16. Optimal control of hydroelectric facilities

    Science.gov (United States)

    Zhao, Guangzhi

    This thesis considers a simple yet realistic model of pump-assisted hydroelectric facilities operating in a market with time-varying but deterministic power prices. Both deterministic and stochastic water inflows are considered. The fluid mechanical and engineering details of the facility are described by a model containing several parameters. We present a dynamic programming algorithm for optimizing either the total energy produced or the total cash generated by these plants. The algorithm allows us to give the optimal control strategy as a function of time and to see how this strategy, and the associated plant value, varies with water inflow and electricity price. We investigate various cases. For a single pumped storage facility experiencing deterministic power prices and water inflows, we investigate the varying behaviour for an oversimplified constant turbine- and pump-efficiency model with simple reservoir geometries. We then generalize this simple model to include more realistic turbine efficiencies, situations with more complicated reservoir geometry, and the introduction of dissipative switching costs between various control states. We find many results which reinforce our physical intuition about this complicated system as well as results which initially challenge, though later deepen, this intuition. One major lesson of this work is that the optimal control strategy does not differ much between two differing objectives of maximizing energy production and maximizing its cash value. We then turn our attention to the case of stochastic water inflows. We present a stochastic dynamic programming algorithm which can find an on-average optimal control in the face of this randomness. As the operator of a facility must be more cautious when inflows are random, the randomness destroys facility value. Following this insight we quantify exactly how much a perfect hydrological inflow forecast would be worth to a dam operator. In our final chapter we discuss the

  1. Feasibility determination of hydroelectric power generation at Patillas Reservoir, Puerto Rico. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Huetter, J.J. Jr.

    1979-02-01

    The overall feasibility of retrofit for hydroelectric power generation at the Patillas Reservoir, an existing impoundment located near the town of Patillas, Puerto Rico, was studied. The scope of work and project intent is limited to establishing valid acceptance or non-acceptance criteria for this specific site as an example of power generation potential at existing dams of relatively low head (less than or equal to 20 m) in the United States. Information is included on hydrologic conditions at the site, retrofit plant design, economic analysis, environmental, legal, social and institutional aspects, and availability of plant equipment. It is concluded that generation of hydropower at Patillas is entirely practical and uncomplicated from an engineering viewpoint, has no adverse environmental effects and is economically justifiable for the island of Puerto Rico. The final agency or contractor roles for development are reasonably well-established. There are no prohibitory laws or regulations concerning this development. In fact, according to Puerto Rico legislation, such hydropower developments appear to be mandated. The installed capacity of the site ranges from 665 kW to approximately 1500 kW depending on extent of development of the available options. (LCL)

    The impacts of climate and socioeconomic change in the future are important factors to consider when discussing the issues of sustainable development in the Pacific Islands, since their impacts here are relatively large compared to those in other regions due to the severe limitation of internal resources and the external dependency of the life essentials. The tourism industry is the key driving force behind the economic growth in island region and it is promoted by the environmental attractions. This study constructs scenarios that foresees the effects of these changes and assesses the subsequent impact on both the local community and the tourism industry. In this study, the scenarios have been developed based on the representative concentration pathways (RCPs) and the shared socioeconomic pathways (SSPs). The progress of climate change was expected to affect the attraction of tourists as well as resources availability and food production. The difference of SSPs was expected to affect the quality of life in the local society and the quantity and/or the quality of tourism. A downscale and bias-correction using a local dataset was applied to assess the impacts of climate change, and the relationships between GDP, population, and estimated land availability in the current situation were applied to assess the impact of socioeconomic change. As case studies, the scenarios were constructed to assess the impacts in the Republic of Palau and Ishigaki Island, Japan. Both are typical islands where tourism is the main industry. The situation of environmental resources, local society, and tourism under changing climate and socioeconomic conditions was assessed using these scenarios. The creation of reasonable projections under appropriate scenarios can contribute to sustainable development not only in these islands but also in most Pacific Islands.

  3. Sound cable crossing brings inexpensive electric power to Long Island

    This paper reports that while many electric-utility customers in New York State benefit from inexpensive hydroelectric power from Canada and upstate New York, lack of sufficient transmission connections have prevented this electricity from reaching Long Island. However, a newly constructed underground/underwater link capable of carrying 700-MW now transmits low-cost electricity to the island, saving money for customers. The self-contained fluid-filled cable used for the underwater portion of the project is the largest underwater cable in the world. The use of high-pressure, fluid-filled pipe-type cable on the land portion represents the largest application of paper-polypropylene-paper (PPP) insulated cable in the United States. State-of-the-art technologies were implemented in the use of temperature monitoring and leak detection systems, SF 6 gas-insulated substation, and underwater cable laying and embedment techniques

    1976-10-01

    A review of published literature and available data on the ecology of hydroelectric reservoirs and other lakes in Puerto Rico yielded various studies on unrelated elements in the aquatic ecology, but very few comprehensive investigations. The majority of the island-wide studies pertained to surveys on snails related to the parasitic disease bilharzia. A survey of 28 major lakes in 1976 showed that Biomphalaria glabrata had gradually been displaced from most of the lakes by Marisa cornuarietis and Tarebia granifera, two foreign snails which do not transmit bilharzia. Of the 17 lakes containing B. glabrata in 1956, only 8 remained infested in 1966 and only 5 in 1976, twenty years after the introduction of Marisa cornuarietis. Although the trend indicates that the lakes may be safe from transmission a monitoring system is necessary before the lakes could be used for recreation.

    The Solomon Islands have an area of about 30,000 square kilometers. The larger islands are volcanic and contain a small variety of minerals, some of which may eventually be economically recoverable. A large phosphate deposit may also be mined at some future date. Specific geologic information is very difficult to find, but on the basis of what little is available a small potential is deduced to be in Category 2 (l,000 - 10,000 tonnes U). (author

    The South Bay Salt Pond Restoration Project aims to restore 50–90 percent of former salt evaporation ponds into tidal marsh in South San Francisco Bay, California. However, large numbers of waterbirds use these ponds annually as nesting and foraging habitat. Islands within ponds are particularly important habitat for nesting, foraging, and roosting waterbirds. To maintain current waterbird populations, the South Bay Salt Pond Restoration Project plans to create new islands within former salt ponds in South San Francisco Bay. In a series of studies, we investigated pond and individual island attributes that are most beneficial to nesting, foraging, and roosting waterbirds.

  14. Public choice in water resource management: two case studies of the small-scale hydroelectric controversy

    Energy Technology Data Exchange (ETDEWEB)

    Soden, D.L.

    1985-01-01

    Hydroelectric issues have a long history in the Pacific Northwest, and more recently have come to focus on developing environmentally less-obtrusive means of hydroelectric generation. Small-scale hydroelectric represents perhaps the most important of these means of developing new sources of renewable resources to lessen the nation's dependence on foreign sources of energy. Each potential small-scale hydroelectric project, however, manifests a unique history which provides a highly useful opportunity to study the process of collective social choice in the area of new energy uses of water resources. Utilizing the basic concepts of public choice theory, a highly developed and increasingly widely accepted approach in the social sciences, the politicalization of small-scale hydroelectric proposals is analyzed. Through the use of secondary analysis of archival public opinion data collected from residents of the State of Idaho, and through the development of the two case studies - one on the Palouse River in Eastern Washington and the other at Elk Creek Falls in Northern Idaho, the policy relevant behavior and influence of major actors is assessed. Results provide a useful test of the utility of public-choice theory for the study of cases of natural-resources development when public involvement is high.

    When the 10-MW Wailuku River Hydroelectric Project begins operating this summer, the island of Hawaii will reduce its dependence on oil. The project is illustrative of what must be done to add to the electricity supply and, at the same time, to protect the environment. The Wailuku project is the first hydro plant to be developed in Hawaii in more than 50 years and is the largest hydro facility ever built in the state. The project is being developed by Wailuku River Hydroelectric Power Co., a wholly owned subsidiary of Synergics, Inc. Hawaii Electric Light Company Inc. (HELCO) will buy the electricity generated at the project for 30 years on an as-delivered basis at its avoided cost rate, now approximately 6.71 cents per kilowatt-hour, the floor rate in the contract. The Wailuku endeavor receives rave reviews form the mayor of Hilo, the president of the utility, and local residents. The project demanded a high degree of sensitivity to environmental issues and the uniqueness of the Hawaiian culture and island setting, according to Wayne Rogers, president of Wailuku River Hydro. From the conception of this project, we have worked closely with state and local interests and have been committed to following Hawaii's plans for land use and environmentally responsible energy development

The stratigraphy of the Dixon Island (3195+15Ma) -Cleaverville (3108+13Ma) formations shows the well preserved environmental condition at the Mesoarchean ocean floor. The stratigraphy of these formations are formed about volcano-sedimentary sequences with hydrothermal chert, black shale and banded iron formation to the top. Based on the scientific drilling of DXCL project at 2007 and 2011, detail lithology between BIF sequence was clearly understood. Four drilling holes had been done at coastal sites; the Dixon Island Formation is DX site (100m) and the Cleaverville Formation is CL2 (40m), CL1 (60m) and CL3 (200m) sites and from stratigraphic bottom to top. Coarsening and thickening upward black shale-BIF sequences are well preserved of the stratigraphy form the core samples. The Dixon Island Formation consists komatiite-rhyolite sequences with many hydrothermal veins and very fine laminated cherty rocks above them. The Cleaverville Formation contains black shale, fragments-bearing pyroclastic beds, white chert, greenish shale and BIF. The CL3 core, which drilled through BIF, shows siderite-chert beds above black shale identified before magnetite lamination bed. U-Pb SHRIMP data of the tuff in lower Dixon Island Formation is 3195+15 Ma and the pyroclastic sequence below the Cleaverville BIF is 3108+13 Ma. Sedimentation rate of these sequence is 2-8 cm/ 1000year. The hole section of the organic carbon rich black shales below BIF are similar amount of organic content and 13C isotope (around -30per mill). There are very weak sulfur MIF signal (less 0.2%) in these black shale sequence. Our result show that thick organic rich sediments may be triggered to form iron rich siderite and magnetite iron beds. The stratigraphy in this sequence quite resemble to other Iron

    Small hydroelectric power plants (SHPs) have a definite role to play in the contemporary energy scenario generally as a source for supplementing the electrical energy production and particularly in remote rural areas in meeting the energy requirements of isolated communities. SHPs practically do not produce any adverse impact.However, their success depends on the ingenuity of the planners and the designers, and more importantly the convection. Another dimension to the success is the participation and involvement of the beneficiaries of the project which are more relevant for the microhydro electric schemes in the remote areas. The major factor that influences the commercial success of the SHP is marketing. It should be given due emphasis. This necessitates the SHP development activities to be more pragmatic and relevant to the society needs; an approach which is programme-based, rather than a project-oriented, is needed.

  7. Benefits and applications of modular hydroelectric pumped storage

    International Nuclear Information System (INIS)

    Koebbe, R.S.

    1991-01-01

    This paper reports on hydroelectric pumped storage which is the only proven and most efficient technology available for energy storage. It is used by utilities to provide peak and intermediate power and to optimize overall system performance. Because of increased environmental and regulatory constraints, few acceptable sites, long schedules, and huge financial commitments, large conventional pumped storage plants, are now virtually impossible to build. As an alternative, small modular pumped storage, with project sizes ranging from 25 MW to 200 MW, was created to overcome the difficulties of conventional projects. The modular approach involves standardizing the elements of a pumped storage plant by utilizing specialized siting techniques and optimizing design, equipment, and construction. Compared with conventional pumped storage, the modular design can reduce cost and expedite schedule; reduce environmental concerns and permitting obstacles; and expand applications of energy storage on a utility's system

    The Partnership Agreement on Economic and Community Development in Nunavik is intended to accelerate development of natural resources in Nunavik and promote autonomy of the Inuit regional organizations. This can be accomplished through hydroelectric projects, mining, sport hunting, outfitting and tourism. In recent years, activities in these domains have raised fundamental questions pertaining to the advantages and disadvantages of resource development. The role that the Impact Benefit Agreement has on business opportunities has been examined more closely. The results of the Impact Benefit Agreement and its implication for the Cree Nation and hydro development in untapped regions of northern Quebec were described along with the role of the parties in financing future projects. An overview of the costs, benefits and considerations for hydro opportunities in northern Quebec was presented with reference to the electricity grid and the incentives for large investment. 1 fig.

    Final Technical Report for the Recovery Act Project for the Installation of a Low Flow Unit at the Abiquiu Hydroelectric Facility. The Abiquiu hydroelectric facility existed with two each 6.9 MW vertical flow Francis turbine-generators. This project installed a new 3.1 MW horizontal flow low flow turbine-generator. The total plant flow range to capture energy and generate power increased from between 250 and 1,300 cfs to between 75 and 1,550 cfs. Fifty full time equivalent (FTE) construction jobs were created for this project - 50% (or 25 FTE) were credited to ARRA funding due to the ARRA 50% project cost match. The Abiquiu facility has increased capacity, increased efficiency and provides for an improved aquatic environment owing to installed dissolved oxygen capabilities during traditional low flow periods in the Rio Chama. A new powerhouse addition was constructed to house the new turbine-generator equipment.

  10. The hydrogen economy urgently needs environmentally sustainable hydroelectricity

    Goodland, R.

    1995-01-01

    Only two sources of energy were said to have the capacity to bridge the transition to fully sustainable and renewable energy, namely natural gas and hydro. The argument was made that because of this advantage, both forms will have to be promoted fast, since the transition to sustainable energy is urgent. In so far as natural gas supplies are concerned, it was estimated that they will last for perhaps the next 50 years, whereas hydroelectric potential is practically unlimited. Developing nations could vastly accelerate their development, reduce poverty and approach sustainability by exporting hydro to industrial countries. Similarly, industrial nations switching from fossil fuels to hydrogen could move up the environmental ranking, and significantly help alleviating global pollution and climate risks. Environmental ranking of new energy sources, world reservoirs of hydroelectric power, environmental and social ranking of hydro sites, the environmental impacts of hydro projects, and the concept of environmental sustainability in hydro reservoirs, were summarized. Greater acceptance of the need for sustainable development by the hydro industry was urged, along with more care in selecting hydro development sites with sustainability as a prime objective. 23 refs., 6 figs

  11. Behind an ambitious megaproject in Asia: The history and implications of the Bakun hydroelectric dam in Borneo

    2011-01-01

    Using a case-study, inductive, narrative approach, this article explores the history, drivers, benefits, and barriers to the Bakun Hydroelectric Project in East Malaysia. Situated on the island of Borneo, Bakun Dam is a 204 m high concrete face, rock filled dam on the Balui River in the Upper Rajang Basin in the rainforests of Sarawak. Bakun Dam and its affiliated infrastructure could be the single largest and most expensive energy project ever undertaken in Southeast Asia. Based on data collected through site visits, original field research in Sarawak, and more than 80 research interviews, the article begins by teasing out the complex history and drivers behind the Bakun project before identifying a set of potential social, political, and economic benefits the project could deliver. It then delves into six sets of barriers in the technical, economic, political, legal and regulatory, social, and environmental realms. We find that Bakun illustrates how centralized energy megaprojects, while ostensibly championed for reasons of economies of scale and the ability to bring about transformational change in the shortest period of time, often fail to address broader development goals such as fighting energy poverty and improving the livelihoods of the local communities they are supposed to serve. - Highlights: → Bakun Dam is concrete face, rock filled dam on the Balui River in the Upper Rajang Basin in the rainforests of Sarawak. → The project faces technical, economic, political, legal and regulatory, social, and environmental barriers. → We conclude the project will fail to fight energy poverty or improve the livelihoods of local populations.

    Thurland, Karen C.

    The purpose of conducting this study was to describe the experience of elementary teachers in a mathematics and science staff development project in the U.S. Virgin Islands. The focus of this study was to describe the meaning teachers attribute to their experience in this three year project, in which many of the national mathematics and science reform efforts were implemented. A phenomenological approach was used in order to develop a complete picture of the teachers' experiences. Data collection consisted of interviews with seven elementary teachers. The data were subjective descriptions of the teachers pertaining to the initial summer institute, the follow-up sessions, and the new innovative methods. The transcendental phenomenological model was used. The textural and structural themes included enhanced learning and changes in teaching practice, and interactions with colleagues. From these themes, individual and composite textual descriptions of the experience of the teacher participants were developed. The synthesis of those descriptions illuminated the meanings and essence of their lived experience. The findings indicate that the essence of the experience was the development of a positive attitude towards the teaching of math and science. The teachers gained confidence in their ability to motivate students with the inquiry method and taught more math and science. The implications for the Virgin Islands Department of Education include establishing a partnership with the local university to offer staff development training in mathematics and science and to conduct evaluations of its training efforts.

  14. Projected atoll shoreline and run-up changes in response to sea-level rise and varying large wave conditions at Wake and Midway Atolls, Northwestern Hawaiian Islands

    Atoll islands are dynamic features that respond to seasonal alterations in wave conditions and sea level. It is unclear how shoreline wave run-up and erosion patterns along these low elevation islands will respond to projected sea-level rise (SLR) and changes in wave climate over the next century, hindering communities' preparation for the future. To elucidate how these processes may respond to climate change, extreme boreal winter and summer wave conditions under future sea-level rise (SLR) and wave climate scenarios were simulated at two atolls, Wake and Midway, using a shallow-water hydrodynamic model. Nearshore wave conditions were used to compute the potential longshore sediment flux along island shorelines via the CERC empirical formula and wave-driven erosion was calculated as the divergence of the longshore drift; run-up and the locations where the run-up exceed the berm elevation were also determined. SLR is projected to predominantly drive future island morphological change and flooding. Seaward shorelines (i.e., ocean fronted shorelines directly facing incident wave energy) were projected to experience greater erosion and flooding with SLR and in hypothetical scenarios where changes to deep water wave directions were altered, as informed by previous climate change forced Pacific wave modeling efforts. These changes caused nearshore waves to become more shore-normal, increasing wave attack along previously protected shorelines. With SLR, leeward shorelines (i.e., an ocean facing shoreline but sheltered from incident wave energy) became more accretive on windward islands and marginally more erosive along leeward islands. These shorelines became more accretionary and subject to more flooding with nearshore waves becoming more shore-normal. Lagoon shorelines demonstrated the greatest SLR-driven increase in erosion and run-up. They exhibited the greatest relative change with increasing wave heights where both erosion and run-up magnitudes increased. Wider

    Vargas, Asdrubal G.

    2016-01-01

    A pumping test was carry out during 2560 minutes with an average flow rate of 1,9 l/s, using a submersible pump of 5,6 kW, in order to determine the hydrogeological parameters of the fractured confined aquifer founded in the dam site of the Pirris Hydroelectric Power. A significant change in the drawdowns values was observed in four piezometers, approximately 420 minutes after the beginning of the pumping test. This was caused by an earthquake with a magnitude of 6.2 M_w with an epicenter near the town of Golfito (133,7 km far away). After the event a recovery of the groundwater level in all piezometers were recorded, although the well continued with the extraction process. Five phases were identified using the recorded level and the time. Phase 1, a drawdown of groundwater level was caused by pumping with a 6-hour period; the second phase was shown a sharp recovery as a result of the earthquake. The third phase was related to stabilization levels after the earthquake, however then a new level recovery phase was occurred due to several aftershocks. Finally another period of small drawdown was presented. After the test the data were reviewed to determine the effect of various parameters. For example partial penetration of the well, and the dip of the aquifer. From this preliminary analysis it was concluded that these factors did not influence the traditional method for the estimation of hydrodynamic parameters, therefore it was decided to analyze the data by the method of Theis and Moench for confined and fractured aquifers respectively.

This article synthesizes discussion of collaborative research results, interventions and policy engagement for St Lawrence Island (SLI, Alaska, during the years 2000–2012. Methods . As part of on-going community-based participatory research (CBPR studies on SLI, 5 discrete exposure-assessment projects were conducted: (a a biomonitoring study of human blood serum; (b–d 3 investigations of levels of contaminants in environmental media at an abandoned military site at Northeast Cape – using sediment cores and plants, semi-permeable membrane devices and blackfish, respectively; and (e a study of traditional foods. Results . Blood serum in residents of SLI showed elevated levels of polychlorinated biphenyls (PCBs with higher levels among those exposed to the military site at Northeast Cape, an important traditional subsistence-use area. Environmental studies at the military site demonstrated that the site is a continuing source of PCBs to a major watershed, and that clean-up operations at the military site generated PCB-contaminated dust on plants in the region. Important traditional foods eaten by the people of SLI showed elevated concentrations of PCBs, which are primarily derived from the long-range transport of persistent pollutants that are transported by atmospheric and marine currents from more southerly latitudes to the north. Interventions . An important task for all CBPR projects is to conduct intervention strategies as needed in response to research results. Because of the findings of the CBPR projects on SLI, the CBPR team and the people of the Island are actively engaging in interventions to ensure cleanup of the formerly used military sites; reform chemicals policy on a national level; and eliminate persistent pollutants internationally. The goal is to make the Island and other northern/Arctic communities safe for themselves and future generations. Conclusions . As part of the CBPR projects conducted from 2000 to 2012

    The energy challenges of the next 30 years appear daunting and, in certain cases, in conflict with one another. Their complexity is such that one solution alone cannot provide a full answer. It is nevertheless equally clear that hydro-electricity, being renewable, proven, highly efficient, storable and with still very significant resource potential, possesses a unique combination of attributes which will aid decision-makers to plan and execute energy development with confidence.

    Hydroelectric power is the most mature and widely implemented of the renewable energy technologies. The energy of flowing water has been used to perform work directly since ancient times, and the use of hydropower turbines to generate electricity traces back to the 19th century. Two commonly used turbine types, the Francis and Kaplan turbines, are essentially refinements of the simple reaction turbine of Hero of Alexandria, dating from about 100 B.C. (NAS 1976). Hydroelectric power production provides over 10% of the net electrical generation in the US, more than petroleum or natural gas and far more than the other renewable energy technologies combined. On a regional basis, hydroelectric power represents 14% of the net electrical power generation in the Rocky Mountain states and nearly 63% along the Pacific Coast. Those states that have the largest percentages of their electricity generated by hydropower (e.g., Idaho, Oregon, Montana, and Washington) also tend to have the lowest average cost of electricity per kilowatt-hour

    2017-10-01

    In recent years, distributed renewable energy-generation technologies, such as wind and solar, have developed rapidly. Nevertheless, the utilization of ultra-low-head (ULH) water energy (i.e., situations where the hydraulic head is less than 3 m or the water flow is more than 0.5 m/s with zero head) has received little attention. We believe that, through technological innovations and cost reductions, ULH hydropower has the potential to become an attractive, renewable, and sustainable resource. This paper investigates potential sites for ULH energy resources, the selection of relevant turbines and generators, simplification of civil works, and project costs. This review introduces the current achievements on ULH hydroelectric technology to stimulate discussions and participation of stakeholders to develop related technologies for further expanding its utilization as an important form of renewable energy.

    2017-09-12

    The abundance of marine macro-debris was quantified with high spatial resolution by applying an image processing technique to archived shoreline aerial photographs taken over Vancouver Island, Canada. The photographs taken from an airplane at oblique angles were processed by projective transformation for georeferencing, where five reference points were defined by comparing aerial photographs with satellite images of Google Earth. Thereafter, pixels of marine debris were extracted based on their color differences from the background beaches. The debris abundance can be evaluated by the ratio of an area covered by marine debris to that of the beach (percent cover). The horizontal distribution of percent cover of marine debris was successfully computed from 167 aerial photographs and was significantly related to offshore Ekman flows and winds (leeway drift and Stokes drift). Therefore, the estimated percent cover is useful information to determine priority sites for mitigating adverse impacts across broad areas. Copyright © 2017 Elsevier Ltd. All rights reserved.

  13. Impact of the Vancouver Island natural gas pipeline construction on water quality: Project report

    Energy Technology Data Exchange (ETDEWEB)

    Li, G

    1993-01-01

    Prior to the construction of the Vancouver Island natural gas pipeline, concern was expressed for the potential defilement of community domestic water supplies when the construction work occurred in community watersheds. When drinking water becomes turbid from rainfall runoff passing through construction sites, the community disinfection process is rendered inefficacious. At a specified turbidity level, the water becomes too risky to drink without alternative disinfection such as boiling. This situation creates significant administrative problems for local health officials, intolerable social problems for residents and processing problems for industries which require clean water. This document is a review of the weekly environmental surveillance reports submitted by D. Tripp Biological Consultants to the B.C. Utilities Commission. The material is organized to relate construction practices with weather patterns thereby showing the resultant effects on water quality (turbidity).

    Full Text Available With the long construction period, the giant scope and complex technology, water conservancy and hydroelectric engineering construction has large investment. In the fully competitive water conservancy and hydropower project construction contracting market, it is almost impossible for a company to contract with a water conservancy and hydropower project independently. Therefore, water conservancy and hydropower project construction can be contracted by several construction companies together, to play each company's strengths, lower offer, improve project quality, shorten the construction period and win the competition. In this paper, we started from the definition of Joint Venture, summed up the forms of Joint Venture in water conservancy and hydropower engineering, proposed that the JV modes can be divided into domestic and international union, tight mode, half-tight mode, loose mode, incorporation and consortium. Furthermore, we analyzed the advantages and disadvantages of Joint Venture. Put forward that the JV can relieve the owner from interfacial administrative work, reduce risk of engineering, and raise the success rate of engineering contract, improve the correctness of price and increase the opportunity of project contracting, Learn from other members, enhance technology and management and make full use of idle resources

To analyze the factors of the soil settlement in a marine reclamation project, the SEM method in the soil micro-structural analysis method is used to test and study six soil samples such as the representative silt, mucky silty clay, silty clay and clay in the area. The structural characteristics that affect the soil settlement are obtained by observing the SEM charts at different depths. By combining numerical calculation method of Terzaghi’s one-dimensional and Biot’s two-dimensional consolidation theory, the one-dimensional and two-dimensional creep models are established and the numerical calculation results of two consolidation theories are compared in order to predict the maximum settlement of the soils 100 years after completion. The analysis results indicate that the micro-structural characteristics are the essential factor to affect the settlement in this area. Based on numerical analysis of one-dimensional and two-dimensional settlement, the settlement law and trend obtained by two numerical analysis method is similar. The analysis of this paper can provide reference and guidance to the project related to the marine reclamation land.

  17. Climate change impact on operation of dams and hydroelectricity generation in the Northeastern United States

    2016-12-01

    We are using a large-scale, high-resolution, fully integrated hydrological/reservoir/hydroelectricity model to investigate the impact of climate change on the operation of 11037 dams and generation of electricity from 375 hydroelectric power plants in the Northeastern United States. Moreover, we estimate the hydropower potential of the region by energizing the existing non-powered dams and then studying the impact of climate change on the hydropower potential. We show that climate change increases the impact of dams on the hydrology of the region. Warmer temperatures produce shorter frozen periods, earlier snowmelt and elevated evapotranspiration rates, which when combined with changes in precipitation, are projected to increase water availability in winter but reduce it during summer. As a result, the water that is stored by dams will be more than ever a necessary part of the routine water systems operations to compensate for these seasonal imbalances. The function of dams as emergency water storage for creating drought resiliency will mostly diminish in the future. Building more dams to cope with the local impacts of climate change on water resources and to offset the increased drought vulnerability may thus be inevitable. Annual hydroelectricity generation in the region is 41 Twh. Our estimate of the annual hydropower potential of non-powered dams adds up to 350 Twh. Climate change may reduce hydropower potential from non-powered dams by up to 13% and reduce current hydroelectricity generation by up to 8% annually. Hydroelectricity generation and hydropower potential may increase in winter months and decline in months of summer and fall. These changes call for recalibration of dam operations and may raise conflict of interests in multipurpose dams.

    Full Text Available Background and Purpose: In every organization, project management raises many different decision-making problems, a large proportion of which can be efficiently solved using specific decision-making support systems. Yet such kinds of problems are always a challenge since there is no time-efficient or computationally efficient algorithm to solve them as a result of their complexity. In this study, we consider the problem of optimal financial investment. In our solution, we take into account the following organizational resource and project characteristics: profits, costs and risks.

    Hydropower investments have been subject to intense criticism over environmental issues and the common experience with cost uncertainty. In this study we address the issue of uncertainty in cost projections by applying reference class forecasting (RCF) in order to improve the reliability of costs used for making decisions under uncertainty. This technique makes it possible to closely link contingency estimates to the likely incidence of uncertainty of construction costs for hydroelectric dams...

    This study assesses the possible changes in rainfall patterns of Sarawak in Borneo Island due to climate change through statistical downscaling of General Circulation Models (GCM) projections. Available in-situ observed rainfall data were used to downscale the future rainfall from ensembles of 20 GCMs of Coupled Model Intercomparison Project phase 5 (CMIP5) for four Representative Concentration Pathways (RCP) scenarios, namely, RCP2.6, RCP4.5, RCP6.0 and RCP8.5. Model Output Statistics (MOS) based downscaling models were developed using two data mining approaches known as Random Forest (RF) and Support Vector Machine (SVM). The SVM was found to downscale all GCMs with normalized mean square error (NMSE) of 48.2-75.2 and skill score (SS) of 0.94-0.98 during validation. The results show that the future projection of the annual rainfalls is increasing and decreasing on the region-based and catchment-based basis due to the influence of the monsoon season affecting the coast of Sarawak. The ensemble mean of GCMs projections reveals the increased and decreased mean of annual precipitations at 33 stations with the rate of 0.1% to 19.6% and one station with the rate of - 7.9% to - 3.1%, respectively under all RCP scenarios. The remaining 15 stations showed inconsistency neither increasing nor decreasing at the rate of - 5.6% to 5.2%, but mainly showing a trend of decreasing rainfall during the first period (2010-2039) followed by increasing rainfall for the period of 2070-2099.

  2. Small hydroelectricity at the low point?

    International Nuclear Information System (INIS)

    2015-01-01

    Small hydroelectricity displays an interesting potential in France (about 1.000 MW), but, as outlined in this article and despite technological advances, this sector is not growing significantly, notably for regulatory reasons: there is no consensus on the impact of these constructions on the environment. The article also outlines that development costs are always higher. These environmental and economic issues result in a transformation of the sector: old and ageing plants owned by individuals are sold to other actors, forms of deregulation are appearing to support the development. In parallel, the article notices that installations depend on their geographical context, and that it is also possible to produce electricity in plains

    Though evidencing a power demand which is amongst the lowest in the world, the sub-Saharan regions of Africa are blessed with an enormous hydroelectric power resource potential, which, if suitably developed and tapped, may become a source of economic electric energy for Europe. With the aid of numerous statistical supply and demand data, this paper surveys the marketing potential of this energy source in Africa. The analysis of future development prospects is carried out with reference to the local socio-economic framework

  4. The hydroelectric power market in the United States

    International Nuclear Information System (INIS)

    2002-01-01

    The second-largest producer of hydroelectric power in the world is the United States, right after Canada. In the United States, 7.1 per cent of net electricity generation was attributed to hydroelectric power in 2000, which totalled 269 terawatt hours (TWh). Aging facilities, outdated technology in some facilities, a cumbersome licensing process, and increasing environmental demands from interest groups for the preservation of river systems and surrounding wildlife challenge the industry. Pacific Coast states, especially California, were faced with electric power shortages during the summer of 2001, due to low market prices, high power usage among consumers and drought. The problems with the deregulation of the electricity market were brought to light by these shortages. Legislation to restructure the electric power industry in 25 states had not been enacted as of January 2002. The purchase of more power from both Canada and the Mexico is being considered by the government of the United States, as is the creation of a national power grid to allow for power transmission throughout the country. The Canada-United States energy trade might be affected by such a move, and result in project construction opportunities for Canadian companies. Renewable energy sources must be responsible for the generation of 10 per cent of power generation levels by 2020, on a gradual basis as mandated by law. By 2005, New York City must purchase 10 per cent of its power from renewable energy sources, reaching 20 per cent by 2010. The repair and replacement of aging dam equipment, the development of advanced turbine technology to protect fish stocks and water quality, dam removal, the construction of power lines are all opportunities open to Canadian companies. 60 refs., 5 tabs

  5. Projected poleward shift of king penguins' (Aptenodytes patagonicus) foraging range at the Crozet Islands, southern Indian Ocean.

    Seabird populations of the Southern Ocean have been responding to climate change for the last three decades and demographic models suggest that projected warming will cause dramatic population changes over the next century. Shift in species distribution is likely to be one of the major possible adaptations to changing environmental conditions. Habitat models based on a unique long-term tracking dataset of king penguin (Aptenodytes patagonicus) breeding on the Crozet Islands (southern Indian Ocean) revealed that despite a significant influence of primary productivity and mesoscale activity, sea surface temperature consistently drove penguins' foraging distribution. According to climate models of the Intergovernmental Panel on Climate Change (IPCC), the projected warming of surface waters would lead to a gradual southward shift of the more profitable foraging zones, ranging from 25 km per decade for the B1 IPCC scenario to 40 km per decade for the A1B and A2 scenarios. As a consequence, distances travelled by incubating and brooding birds to reach optimal foraging zones associated with the polar front would double by 2100. Such a shift is far beyond the usual foraging range of king penguins breeding and would negatively affect the Crozet population on the long term, unless penguins develop alternative foraging strategies.

    Ornamental marine species (`OMS') provide valuable income for developing nations in the Indo-Pacific Coral Triangle, from which most of the specimens are exported. OMS culture can help diversify livelihoods in the region, in support of management and conservation efforts to reduce destructive fishing and collection practices that threaten coral reef and seagrass ecosystems. Adoption of OMS culture depends on demonstrating its success as a livelihood, yet few studies of OMS culture exist in the region. We present a case study of a land-based culture project for an endangered seahorse ( Hippocampus barbouri) in the Spermonde Islands, Sulawesi, Indonesia. The business model demonstrated that culturing can increase family income by seven times. A Strengths Weaknesses Opportunities Threats (SWOT) analysis indicated good collaboration among diverse stakeholders and opportunities for culturing non-endangered species and for offshoot projects, but complicated permitting was an issue as were threats of market flooding and production declines. The OMS international market is strong, Indonesian exporters expressed great interest in cultured product, and Indonesia is the largest exporting country for H. barbouri. Yet, a comparison of Indonesia ornamental marine fish exports to fish abundance in a single local market indicated that OMS culture cannot replace fishing livelihoods. Nevertheless, seahorse and other OMS culture can play a role in management and conservation by supplementing and diversifying the fishing and collecting livelihoods in the developing nations that provide the majority of the global OMS.

    Fifteen samples recovered from the lower head of the Three Mile Island (TMI) Unit 2 nuclear reactor pressure vessel were subjected to detailed metallurgical examinations by the Idaho National Engineering Laboratory (INEL), with supporting work carried out by Argonne National Laboratory (ANL) and several of the European participants. These examinations determined that a portion of the lower head, a so-called elliptical ``hot spot`` measuring {approx}0.8 {times} 1 m, reached temperatures as high as 1100{degrees}C during the accident and cooled from these temperatures at {approx}10--100{degrees}C/min. The remainder of the lower head was found to have remained below the ferrite-toaustenite transformation temperature of 727{degrees}C during the accident. Because of the significance of these results and their importance to the overall analysis of the TMI accident, a panel of three outside peer reviewers, Dr. Robert W. Bohl, Mr. Richard G. Gaydos, and Mr. George F. Vander Voort, was formed to conduct an independent review of the metallurgical analyses. After a thorough review of the previous analyses and examination of photo-micrographs and actual lower head specimens, the panel determined that the conclusions resulting from the INEL study were fundamentally correct. In particular, the panel reaffirmed that four lower head samples attained temperatures as high as 1100{degrees}C, and perhaps as high as 1150--1200{degrees}C in one case, during the accident. They concluded that these samples subsequently cooled at a rate of {approx}50--125{degrees}C/min in the temperature range of 600--400{degrees}C, in good agreement with the original analysis. The reviewers also agreed that the remainder of the lower head samples had not exceeded the ferrite-to-austenite transformation temperature during the accident and suggested several refinements and alternative procedures that could have been employed in the original analysis.

  9. The political economy of Canadian hydro-electricity : between old provincial hydros and neoliberal regional energy regimes

    2007-01-01

    In economic terms, hydro-electricity is considered as a quasi-staple, as it prone to the classic staples problem of excess capacity. However, neither water nor hydroelectricity in Canada is produced primarily for export markets. Hydroelectric systems are often thought of as politicized monopolies. This paper discussed changes that have occurred in hydroelectric organizations over time, as they have been governed by a formative mixed regime; postwar provincial hydro systems; a megaprojects regime; and an emerging sustainability regionalization regime. The origins of electricity generation and transmission in Canada were discussed, as well as the ecological footprint of large mega-projects on rivers. The development of provincial hydro monopolies during the mid- to late- twentieth century was also outlined, as well as the sustainability and regionalization regime that developed after 1990. During the mature staples period of the mid-century, rents in hydro-electric organizations were distributed through cheap rates to subsidize and facilitate the development of mass production and mass consumption. However, post-staples consumption has now replaced mass consumption, and demand side management is replacing earlier cheap power policies. Nonetheless, the lack of systematic integration of networks has led to inefficiencies. Provincial grids are now being integrated into interconnected North American regional networks regulated by the United States. It was concluded that the Canadian electricity regime is increasingly influenced by the the supranational role that the United States is playing in structuring markets. 83 refs

    2014-12-01

    Substantial greenhouse gas (GHG) emissions from hydropower reservoirs have been of great concerns recently, yet the significant carbon emitters of drawdown area and reservoir downstream (including spillways and turbines as well as river reaches below dams) have not been included in global carbon budget. Here, we revisit GHG emission from hydropower reservoirs by considering reservoir surface area, drawdown zone and reservoir downstream. Our estimates demonstrate around 301.3 Tg carbon dioxide (CO2)/year and 18.7 Tg methane (CH4)/year from global hydroelectric reservoirs, which are much higher than recent observations. The sum of drawdown and downstream emission, which is generally overlooked, represents 42 % CO2 and 67 % CH4 of the total emissions from hydropower reservoirs. Accordingly, the global average emissions from hydropower are estimated to be 92 g CO2/kWh and 5.7 g CH4/kWh. Nonetheless, global hydroelectricity could currently reduce approximate 2,351 Tg CO2eq/year with respect to fuel fossil plant alternative. The new findings show a substantial revision of carbon emission from the global hydropower reservoirs.

    The state of development and the technical potential of hydroelectric power worldwide, in Europe and in Switzerland are briefly compared with each other. Afterwards, the most important types of hydroelectric power stations and their function in the electricity-distribution network, are put forward. The realistic possibilities of development in Switzerland, up to the year 2025, of each type of hydroelectric power station is judged with regard to the currently valid regulations. The effects of the peoples' initiative - 'towards the salvation of our waters' or for stricter regulations for the protection of water - on the chances of realisation of these possibilities of development are shown. The forseeable decrease in the production of energy by the existing hydroelectric power stations, as a result of the regulation planned for rest water, is judged. Various forecasts for the future quantity of hydroelectric power production in Switzerland are put forward. 6 figs., 7 tabs., 12 refs

    The Cat Arm Dam hydroelectric development in Newfoundland comprises 10 dams, three tunnels, two canals and a 127 MW powerhouse. The scheme develops 127 MW from 380.5 m of head and comprises: ten dams of varying heights up to 53 m; a bathtub type overflow spillway 330 m in length; a 230 m long inverted U-shaped diversion tunnel; an 800 m long, inverted U-shaped low pressure forebay tunnel; two bog and rock cut tunnels leading to and from the forebay tunnels; a surface powerhouse containing two Pelton turbines; and a 178 km long, 230 kV transmission line. An overview is provided of the environmental assessment, project impacts, and cost of environmental protection associated with the project. Impacts were centered around fish and aquatic life in the created reservoir and downstream of the powerhouse, loss of ungulate (moose and caribou) habitat due to flooding, loss of forestry resources due to flooding, and the disturbance of land during construction. The overall cost of environmental protection was $7,977,000, only 2% of the total project cost. 17 refs., 1 tab

The environment into which the project has been integrated was also described. General background information and technical characteristics of the Laforge-2 and Caniapiscau-Laforge diversion were provided. The Laforge-2 Mitigative Master Plan's measures for improving wildlife potential, cleaning-up of tributaries, protecting wildlife habitats, seeding around ponds and humid zones, installing platforms to encourage and facilitate the nesting of ospreys, and promoting proper harvesting of the territory, were described as corrective measures that will promote sustainable development. Contractual obligations to protect the environment were outlined. Enhancement measures described included reclamation of areas disturbed during construction, landscaping around main structures and construction of scenic lookouts. It was fully expected that the mitigative measures described for the Laforge-2 project will minimize negative impacts of the project and will maximize positive ones by improving wildlife potential in areas near the reservoir. 5 figs

    To describe the research methods and baseline sample of the Talking About The Smokes (TATS) project. The TATS project is a collaboration between research institutions and Aboriginal community-controlled health services (ACCHSs) and their state and national representative bodies. It is one of the studies within the International Tobacco Control Policy Evaluation Project, enabling national and international comparisons. It includes a prospective longitudinal study of Aboriginal and Torres Strait Islander smokers and recent ex-smokers; a survey of non-smokers; repeated cross-sectional surveys of ACCHS staff; and descriptions of the tobacco policies and practices at the ACCHSs. Community members completed face-to-face surveys; staff completed surveys on paper or online. We compared potential biases and the distribution of variables common to the main community baseline sample and unweighted and weighted results of the 2008 National Aboriginal and Torres Strait Islander Social Survey (NATSISS). The baseline survey (Wave 1) was conducted between April 2012 and October 2013. 2522 Aboriginal and Torres Strait Islander people in 35 locations (the communities served by 34 ACCHSs and one community in the Torres Strait), and 645 staff in the ACCHSs. Sociodemographic and general health indicators, smoking status, number of cigarettes smoked per day and quit attempts. The main community baseline sample closely matched the distribution of the Aboriginal and Torres Strait Islander population in the weighted NATSISS by age, sex, jurisdiction and remoteness. There were inconsistent differences in some sociodemographic factors between our sample and the NATSISS: our sample had higher proportions of unemployed people, but also higher proportions who had completed Year 12 and who lived in more advantaged areas. In both surveys, similar percentages of smokers reported having attempted to quit in the past year, and daily smokers reported similar numbers of cigarettes smoked per day. The

    This report contains the final results of investigations concerning the caribou herd south of Ameralik fjord in the period 1982-1985. The purpose of the investigations was to get a background knowledge for evaluating the effects of the proposed hydropower project at Kangerluarsunnguaq/Buksefjord. The herd was estimated to number 2000-2500 individuals in November 1985 and seemed to be slightly increasing. During the investigations the proportion of younger individuals has increased. It is concluded that the herd most years is ''limited'' by snow conditions making a large part of the winter food unavailable. The hydropower project might influence the caribou during calving through construction activities. Furthermore, the transmission line could be expected to influence the use of different areas at different seasons, but it is not expected to exclude the animals from tho coastal areas. A suitable planning of construction activities in relation to season could relieve the effects. 24 refs.

  6. Small-scale hydroelectric power in the Pacific Northwest: new impetus for an old energy source

    Energy Technology Data Exchange (ETDEWEB)

    1980-07-01

    Energy supply is one of the most important issues facing Northwestern legislators today. To meet the challenge, state legislatures must address the development of alternative energy sources. The Small-Scale Hydroelectric Power Policy Project of the National Conference of State Legislators (NCSL) was designed to assist state legislators in looking at the benefits of one alternative, small-scale hydro. Because of the need for state legislative support in the development of small-scale hydroelectric, NCSL, as part of its contract with the Department of Energy, conducted the following conference on small-scale hydro in the Pacific Northwest. The conference was designed to identify state obstacles to development and to explore options for change available to policymakers. A summary of the conference proceedings is presented.

    The US Corps of Engineers' assessment of the nation's hydroelectric resources provides a current and comprehensive estimate of the potential for incremental or new generation at existing dams and other water resource projects, as well as for undeveloped sites in the US. The demand for hydroelectric power is addressed and various related policy and technical considerations are investigated to determine the incentives, constraints, and impacts of developing hydropower to meet a portion of the future energy demands. The comprehensive data represent the effort of the Corps of Engineers based on site-specific analysis and evaluation. Summary tables include estimates of the potential capacity and energy at each site in the inventory. The number of sites and potential capacity in each state are identified, but specific detailed information is included for sites in Colorado, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, and Wyoming.

    Dams influence directly the process of fish migration. Assessing the impact of these infrastructure and direct research for that purpose minimize environmental impacts resulting from projects on biodiversity. Through computer models and probability logistic regressions of occurrence that take into account geomorphologic parameters (elevation and basin area) was obtained a standard distribution model of migratory fishes species in the upper Uruguay river basin (RS/SC) with high calibration (84.39% of adherence). The computational modelling significantly increases the knowledge about methodologies for evaluate environmental impacts caused by small and large dams and applicability in other basins. (author)

    2010-07-01

    This paper presents a methodology for assessing the social-environmental fragility of a watershed where there is potential for installation of hydropower projects. The method includes dividing the watershed into sub areas (by analysis of similar characteristics) and, subsequently, the use of 23 indicators grouped into six social-environmental components (Water Resources and Aquatic Ecosystems, Terrestrial Ecosystems and the Physical Environment, Territorial Organization, Way of Life, Economic Base and Indigenous Communities and Traditional Populations), which together seek to portray all aspects involved in the fragility of the area. The technique was applied in the basin of the Coxim river in the State of Mato Grosso do Sul, assuming that there is interest or the possibility of installing hydropower plants within its boundaries. The basin was divided into three sub areas, considering physical parameters (such as topography, rainfall and hydrology), which were ranked by calculating the fragility of each one of the social-environmental indicators. As a result, a map was created to indicate the sub areas more susceptible to damage and those which should be more resistant to the installation of impacting activities, such as hydropower plants. The use of Geographic Information Systems (GIS) and the work of a multidisciplinary team can reduce the degree of subjectivity of the methodology and allow, (by modifying some considerations inherent in the partial calculations,) its application in other situations where the possibility of installing hydropower projects is not considered.

To evaluate energy generating capacity of water currents and 4. As of the obtained results, to propose alternative for small hydroelectric plants design (PCH) according to defined needs

  11. Potential effects of the Hawaii geothermal project on ground-water resources on the Island of Hawaii

    Energy Technology Data Exchange (ETDEWEB)

    Sorey, M.L.; Colvard, E.M.

    1994-07-01

    This report provides data and information on the quantity and quality of ground-water resources in and adjacent to proposed geothermal development areas on the Island of Hawaii Geothermal project for the development of as much as 500 MW of electric power from the geothermal system in the East Rift Zone of Kilauea Volcano. Data presented for about 31 wells and 8 springs describe the chemical, thermal, and hydraulic properties of the ground-water system in and adjacent to the East Rift Zone. On the basis of this information, potential effects of this geothermal development on drawdown of ground-water levels and contamination of ground-water resources are discussed. Significant differences in ground-water levels and in the salinity and temperature of ground water within the study area appear to be related to mixing of waters from different sources and varying degrees of ground-water impoundment by volcanic dikes. Near Pahoa and to the east, the ground-water system within the rift is highly transmissive and receives abundant recharge from precipitation; therefore, the relatively modest requirements for fresh water to support geothermal development in that part of the east rift zone would result in minimal effects on ground-water levels in and adjacent to the rift. To the southwest of Pahoa, dike impoundment reduces the transmissivity of the ground-water system to such an extent that wells might not be capable of supplying fresh water at rates sufficient to support geothermal operations. Water would have to be transported to such developments from supply systems located outside the rift or farther downrift. Contaminant migration resulting from well accidents could be rapid because of relatively high ground-water velocities in parts of the region. Hydrologic monitoring of observation wells needs to be continued throughout development of geothermal resources for the Hawaii Geothermal Project to enable the early detection of leakage and migration of geothermal fluids.

    Full Text Available Civic, Social and Political Education (CSPE in the Republic of Ireland and Local and Global Citizenship (LGC in Northern Ireland keenly promote students’ active participation in society. However, the purpose of this participation is not necessarily to encourage students to campaign for change in the present but rather that ‘students are given opportunities to engage in actions and develop skills that will contribute to their becoming active participatory citizens in later life’ (NCCA (2005 CSPE Guidelines for Teachers, p. 59. This often gives rise to a culture of passive citizenship and a tendency to focus on ‘action projects’ that are safe and self-contained. This paper focuses on a five action projects carried out by a sample of teachers and students that may be considered ‘controversial’. In each case students actively campaign for equality and social justice, on local or global human rights issues and in ways that may be deemed controversial. It examines how the mainstream curriculum and school structures facilitate or impede this type of controversial action and explores the potential opportunities for greater engagement in such action through proposed curriculum reform.

  13. Improvement of tuberculosis laboratory capacity on Pemba Island, Zanzibar: a health cooperation project.

    Maria G Paglia

    Full Text Available Low-income countries with high Tuberculosis burden have few reference laboratories able to perform TB culture. In 2006, the Zanzibar National TB Control Programme planned to decentralize TB diagnostics. The Italian Cooperation Agency with the scientific support of the "L. Spallanzani" National Institute for Infectious Diseases sustained the project through the implementation of a TB reference laboratory in a low-income country with a high prevalence of TB. The implementation steps were: 1 TB laboratory design according to the WHO standards; 2 laboratory equipment and reagent supplies for microscopy, cultures, and identification; 3 on-the-job training of the local staff; 4 web- and telemedicine-based supervision. From April 2007 to December 2010, 921 sputum samples were received from 40 peripheral laboratories: 120 TB cases were diagnosed. Of all the smear-positive cases, 74.2% were culture-positive. During the year 2010, the smear positive to culture positive rate increased up to 100%. In March 20, 2010 the Ministry of Health and Social Welfare of Zanzibar officially recognized the Public Health Laboratory- Ivo de Carneri as the National TB Reference Laboratory for the Zanzibar Archipelago. An advanced TB laboratory can represent a low cost solution to strengthen the TB diagnosis, to provide capacity building and mid-term sustainability.

    The Ontario Ministry of Natural Resources released a Crown owned site to the private water power industry as part of the small hydro site release program initiated by the Ontario Government in the mid 1980's. The Cordova Lake Dam Hydroelectric Generating Station, built on this site, has been in operation since the first week of October, 1992. Since that time, the plant has been operating with less than 1 % down time and has generated over 2,400 MWh of electricity. Algonquin Power Systems is responsible for the management and operations of the plant which includes full time monitoring from the company's Mississauga office and a part time employee at Cordova Lake. Cordova Lake Dam is located on the Crowe River at the outlet of Cordova Lake, approximately 125 kilometers east of Toronto, Ontario. The total cost of the Cordova Lake Dam project was $1.6 million. Algonquin Power contributed 20% equity to the project. Algonquin Power was also responsible for all engineering and geotechnical work and for completing the construction and equipment contracts. 1 tab., 2 figs

    Because of its maturity, small hydropower generation is one of the main energy sources to be considered for electrification of areas far from the national grid. Once a site with hydropower potential is identified, technical and economical studies to assess its feasibility shall be done. Cost curves are helpful tools in the appraisal of the economical feasibility of this type of projects. This paper presents a method to determine initial cost curves as a function of the average energy production of the hydropower plant, by using a set of parametric cost curves and the flow duration curve at the analyzed location. The method is illustrated using information related to 18 pre-feasibility studies made in 2002, at the Central-Atlantic rural region of Nicaragua. (author)

  16. The adventure of hydroelectricity must continue

    Gravel, C.

    1997-01-01

    An interview with Andre Caille, president and CEO of Hydro-Quebec was presented. The interview focussed on the hydroelectric potential of Hydro-Quebec and open access to the American wholesale market. Hydro-Quebec has the capability to produce 160 to 170 terawatt hours of energy per year which is enough to meet all of Quebec''s needs and to export 12 to 15 per cent. According to M. Caille, research in the field of superconductivity would significantly benefit Hydro-Quebec, since the utility is responsible for 107,000 kilometers of transmission lines. If transmission line losses along those lines could be reduced, power stations could be built even farther from markets. With respect to pricing, Hydro-Quebec continues to sell electricity at regulated prices in Quebec, however, export prices to the U.S. are market driven

  17. Impact of urban heat island on cooling and environment: A demonstration project

    International Nuclear Information System (INIS)

    1993-04-01

    Landscaping has been shown in simulation and field studies to reduce building cooling loads by affecting microclimatic factors such as solar radiation, wind speed and air temperature. A demonstration project was undertaken to determine the magnitude of landscape induced changes in microclimate on building cooling loads and water use on four typical residences in Phoenix, Arizona. The energy use and microclimate of three unlandscaped (bare soil, rock mulch) and one landscaped (turf) home were monitored during summer 1990. In the fall, turf was placed around one of the unlandscaped houses, and shade trees planted on the west and south sides of another. Measurements continued during the summer of 1991. Total house air conditioning and selected appliance electrical data were collected, as well as inside and outside air temperatures. Detailed microclimate measurements were obtained for one to two week periods during both summers. Maximum reductions of hourly outside air temperatures of 1 to 1.5 degrees C, and of daily average air temperatures of up to 1 degrees C, resulted from the addition of turf landscaping. Addition of small trees to the south and west sides of another treatment did not have a noticeable effect on air temperature. Cooling load reductions of 10% to 17% were observed between years when well-watered turf landscaping was added to a house previously surrounded by bare soil. Addition of small trees to another bare landscape did not produce a detectable change in cooling load. The results of the study are used as input to a standard building energy use simulation model to predict landscape effects on cooling load and water usage for three typical houses, and to develop guidelines for use of energy efficient residential landscapes in Phoenix, Arizona

    2002-01-01

    If small hydroelectric power plants are defined to be hydroelectric power plants of up to a few 1000 kW, they should be shelf goods because of cost considerations. Design of small hydroelectric power plants is a many-sided optimization task, on a level with constructing larger hydro power plants. But the budget for a small hydro power plant does not permit any comprehensive evaluations. The most important costs are the one-time costs in the form of investments and the following annual costs in the form of operation and maintenance, and losses. Financing costs are not considered in this article

    1999-01-01

    The NRSE trust fund established with financial support from the Italian Government has succeeded in catalyzing a number of energy projects in small island developing countries. These projects have elicited a great deal of interest by local communities and opened up prospects for further utilization of locally available energy resources. The projects have created a positive impact on the quality of life of people in dispersed locations in small island developing countries by focusing on provision of renewable energy based electricity services such as solar PV lighting for homes, schools, and hospitals; radio, TV, VCR as well as medicine refrigerators. Thus it has become evident that renewable energy technologies such as solar and wind systems can have an important role to play in improving the quality of life of people in these small island countries. Market potential for these technologies is indeed substantial. However constraints and barriers still exist. One of the principal barriers is still the high initial cost of solar devices. Innovative financing including microcredit facilities needs to be explored. Efforts are also needed to strengthen local capacity to undertake assembly of components and systems, and also in the installation, maintenance, and service of renewable energy devices. Entrepreneurial activities need to be fostered through further strengthening of skills in this area. (EHS)

    1980-05-01

    The legal and institutional obstacles to the development of small-scale hydroelectric in West Virginia at the state level are described. The Federal government also exercises extensive regulatory authority in the area. The introductory section examines the dual regulatory system from the standpoint of the appropriate legal doctrine, the law of pre-emption, application of the law to the case of hydroelectric development, and concludes with an inquiry into the practical use of the doctrine by FERC. The development of small-scale hydroelectric energy depends on the selection of a site which will produce sufficient water power capacity to make the project economically attractive to a developer. In West Virginia, the right to use the flowing waters of a stream, creek, or river is appurtenant to the ownership of the lands bordering the watercourse. The lands are known as riparian lands. The water rights are known as riparian rights. Thus, the first obstacle a developer faces involves the acquisition of riparian lands and the subsequent right to the use of the water. The water law in West Virginia is discussed in detail followed by discussions on direct and indirect regulations; continuing obligations; financial considerations; and interstate organizations.

    1980-08-01

    In 1978, the Maine Hydroelectric Development Corporation announced that the company planned to renovate five dams on the Goose River near Belfast, Maine to generate electricity. The most important part of the plan involved the use of the first of the dams, at the lower end of Swan Lake, to regulate the flow of water to the downstream dams. For Maine Hydro, management of the Swan Lake dam could make an otherwise marginal proposal lucrative. However, Swan Lake is vitally important to the residents of Swanville. The town was so concerned about the impact of this proposed hydroelectric project that it petitioned the Federal Energy Regulatory Commission (FERC) to deny Maine Hydro's application on the grounds that it would damage the environment, reduce property values and eliminate recreational opportunities for its citizens. This report was written by the mediator of the dispute and represents the views and behavior of the parties as the mediator understood them. It is intended to present the mediator's observations in a way which will inform and assist others who may someday face a difficult situation like the one the Town of Swanville and Maine Hydroelectric Development Corporation faced, and successfully resolved, in the spring and summer of 1979.

    1991-01-01

    The main features of 46 hydroelectric dams and diversions in British Columbia are reviewed, and available information on the inland sport fish resources within and below the impoundments are summarized. The projects are collectively responsible for ca 95% of the electrical power used in the province. The characteristics detailed include water license and operational constraints, electrical generation, enhancement facilities, operational regime, physical and chemical environment, downstream system, sportfish populations, and recreational fishery. All the hydroelectric impoundments reviewed, with the possible exceptions of some small headponds, support sport fish populations. Recreational angling quality is considered good for about one quarter of impoundments for which information is available. Low population density is the dominant reason for poor angling quality. Drawdowns exceeding 10 m annually and/or low water retention times are significant impediments to sport fish stock densities. Recommended measures to improve sport fishery resources in and below hydroelectric impoundments include evaluation of the efficiency of ongoing compensation programs, improvement to impact assessment procedures to ensure adequate documentation of pre- and post-impoundment conditions, and enhancement of several systems through stock or nutritional supplementation. 161 refs., 95 figs., 9 tabs

    2013-01-01

    France's national debate on energy transition has served as a reminder that hydroelectric power plays a significant role in French electricity production. With installed power totalling 25400 MW at end 2012 (the second largest in Europe), France's hydroelectric plants produced 63.8 TWh last year (the third largest in Europe), almost 12% of total output. It is France's second largest means of producing electricity and it represents more than 80% of production of renewable energy. A source of energy developed a long time ago, thus benefiting from technological maturity, hydroelectricity can be produced in large quantity at the heart of France's regions, while also rendering indispensable service for the equilibrium of the French electricity system by compensating the intermittency of other renewable energy sources. The production costs of hydroelectric power are the lowest among all power generation technologies. (authors)

    Loth, P.

    2001-01-01

    This article discusses the future of hydroelectricity in the light of the ongoing liberalisation of the European power market. Compared to fossil electricity, hydroelectricity is a renewable energy source, has a limited impact on the environment, is able to meet strong variations of power demand, but is a little bit more costly. Hydroelectric companies expect the introduction of a quality label for their product as well as the increasing awareness of consumers for environmental aspects to become strong incentives for them to subscribe on green energy despite its higher cost. The cost difference will also be partly reduced by the introduction of a pollution tax on fossil energy sources. Figures on hydroelectricity capacity production, currently and in the near future, in the countries surrounding the Alps are presented. As an example, the business strategy of a Swiss electricity utility is shortly described

    The VALORAGUA (Value of Water in Portuguese) computer model was developed by Electricidade de Portugal (EDP) in order to determine the optimal operation strategy of a mixed hydro-thermal power system with an important share of hydroelectricity generation such as the one of Portugal. The model has become the main tool used by EDP for planning the development and operation of its power system. In recent years, EDP has acquired the ENPEP package and has become acquainted with its use for integrated energy and electricity planning. The main goal of this effort has been to incorporate in EDP's planning procedure an integrated approach for determining the possible role of electricity in meeting the overall requirements for energy of the country, with due account to the impacts (resource requirements and environmental emissions) of alternative energy and electricity systems. This paper concentrates on a comparison of the results of the BALANCE module of ENPEP for the electricity sector against the simulation results provided by VALORAGUA. Suggested improvements to the methodologies in order to overcome the divergences in results from these two models are also advanced in the paper. (author). 15 figs

    1991-01-01

    As part of the management of a utility, it is necessary to check, beyond the technical aspect, the economic suitability of deciding whether to perform the maintenance or rehabilitation of an installation. The decision criteria involved are to be found within the framework of the utility's management system itself. After having set out the decision-making process of hydroelectric power station maintenance or rehabilitation, the document goes on to give a description of the economic advantage of such an operation. The latter is determined after having properly defined the overall cost of maintenance or rehabilitation: direct expenses and induced costs, and expected savings: economic performance, short and medium-term reduction of expenses as a result of the profitability and productivity of the rehabilitation. The profitability is calculated as the ratio between the economic balance and the amount of the operation. Productivity means the improvement of the utility's management indicators. The random aspect of savings and a simple method making it possible to integrate them into a calculation is mentioned, as well as the classification and aggregation of various operations of a similar nature that have to come into the budget requirements of the utility.

  14. Hydroelectricity at the crossroad: let us give a new momentum to the first renewable energy. White paper on hydroelectricity

    International Nuclear Information System (INIS)

    2017-01-01

    This publication first indicates some data which illustrate the role, importance and development perspectives of hydroelectricity in terms of energy production and in terms of jobs. It outlines that, due to its high adaptation capacity and flexibility, hydroelectricity is an important factor for territory development, that it has a major role in energy supply safety, in the energy mix, and in decentralised energy production. It proposes an overview of the different types of hydroelectric installations: reservoirs for a flexible production and supply safety, run of river hydro systems for a continuous and renewable energy production, pumped storage power stations for mass storage of electric energy. It proposes an overview of assets of hydroelectric energy: implementation of energy transition on the long term, development of an industrial sector of excellence, a responsible and supportive energy, compatibility between hydroelectricity, biodiversity and water usages. Proposals are then formulated to give electricity a new momentum: a new orientation of national and European policies for a better global consistency, a new orientation of economic choices and tax policy as incentives to maintenance and development of the hydroelectric sector, and a fair compensation of services provided to the electric power system

    Load rejection test is one of the essential tests that carried out before the hydroelectric generating set is put into operation formally. The test aims at inspecting the rationality of the design of the water diversion and power generation system of hydropower station, reliability of the equipment of generating set and the dynamic characteristics of hydroturbine governing system. Proceeding from different accident conditions of hydroelectric generating set, this paper presents the transient processes of load rejection corresponding to different accident conditions, and elaborates the characteristics of different types of load rejection. Then the numerical simulation method of different types of load rejection is established. An engineering project is calculated to verify the validity of the method. Finally, based on the numerical simulation results, the relationship among the different types of load rejection and their functions on the design of hydropower station and the operation of load rejection test are pointed out. The results indicate that: The load rejection caused by the accident within the hydroelectric generating set is realized by emergency distributing valve, and it is the basis of the optimization for the closing law of guide vane and the calculation of regulation and guarantee. The load rejection caused by the accident outside the hydroelectric generating set is realized by the governor. It is the most efficient measure to inspect the dynamic characteristics of hydro-turbine governing system, and its closure rate of guide vane set in the governor depends on the optimization result in the former type load rejection.

    Hildebrand, S.G. (ed.)

    1980-10-01

    Potential environmental impacts in reservoirs and downstream river reaches below dams that may be caused by the water level fluctuation resulting from development and operation of small scale (under 25MW) hydroelectric projects are identified. The impacts discussed will be of potential concern at only those small-scale hydroelectric projects that are operated in a store and release (peaking) mode. Potential impacts on physical and chemical characteristics in reservoirs resulting from water level fluctuation include resuspension and redistribution of bank and bed sediment; leaching of soluble organic matter from sediment in the littoral zone; and changes in water quality resulting from changes in sediment and nutrient trap efficiency. Potential impacts on reservoir biota as a result of water level fluctuation include habitat destruction and the resulting partial or total loss of aquatic species; changes in habitat quality, which result in reduced standing crop and production of aquatic biota; and possible shifts in species diversity. The potential physical effects of water level fluctuation on downstream systems below dams are streambed and bank erosion and water quality problems related to resuspension and redistribution of these materials. Potential biological impacts of water level fluctuation on downstream systems below dams result from changes in current velocity, habitat reduction, and alteration in food supply. These alterations, either singly or in combination, can adversely affect aquatic populations below dams. The nature and potential significance of adverse impacts resulting from water level fluctuation are discussed. Recommendations for site-specific evaluation of water level fluctuation at small-scale hydroelectric projects are presented.

    2008-01-01

    Hydroelectricity is a clean and renewable energy source for many countries, and is expected to play an important role in future energy supplies. However, the impact of climatic change on hydroelectricity resources is not yet understood. This study provided a critical review of current methods used to determine the potential impacts of climatic change on hydroelectric power production. General circulation models (GCMs) are used to predict future climate conditions under various greenhouse gas (GHG) emissions scenarios. Statistical techniques are then used to down-scale GCM outputs to the appropriate scales needed for hydrological models, which are then used to simulate the effects of climatic change at regional and local scales. Outputs from the models are then used to develop water management models for hydroelectric power production. Observed linear trends in annual precipitation during the twentieth century were provided. The theoretical advantages and disadvantages of various modelling techniques were reviewed. Risk assessment strategies for Hydro-Quebec were also outlined and results of the study will be used to guide research programs for the hydroelectric power industry. refs., tabs., figs

    The estimates of existing, incremental, and the undeveloped hydropower potential for all states in the various regions of the country are presented. In the Pacific Southwest region, the maximum physical potential for all sites exceeds 33,000 MW of capacity with an estimated average annual energy greater than 85,000 GWH. By comparison, these values represent about 6% of the total potential capacity and hydroelectric energy generation estimated for the entire US. Of the total capacity estimated for the region, 9900 MW has been installed. The remainder (23,200 MW) is the maximum which could be developed by upgrading and expanding existing projects (6000 MW) and by installing new hydroelectric power capacity at all potentially feasible, undeveloped sites (17,200 MW). Small-scale facilities account for less than 4% of the region's total installed capacity, but another 600 MW could be added to these and other small water resource projects. In addition, 600 MW could be installed at potentially feasible, undeveloped small-scale sites. The small-scale resource varies considerably, with the states of California and Utah having the largest potential for incremental development at existing projects in the Pacific Southwest region. States comprising the Southwest are Arizona, California, Hawaii, Nevada, and Utah.

    On our river territories, the development of renewable energy and the restoration of the quality of the aquatic ecosystems both illustrate the need to reconcile the different usages of water resources while still guaranteeing proper functioning of the ecosystems. Hydroelectricity is the crux of the problem. Because of its mountainous hydrographic network and its favourable hydrology, the Adour-Garonne basin witnessed large-scale development of its hydroelectric potential throughout the 20. century. Approaching the question of hydroelectricity from the point of view of the river territories puts all the challenges facing them into their true perspective. Two distinct examples in the Adour-Garonne basin illustrate the partnership between the Water Agency and the local authorities in the Garonne and Dordogne basins: on the Garonne River, reconciling water usages with the maintenance of adequate water levels at times of drought; on the Dordogne River, reducing the impact of the hydro-peaking.

    Tropical hydroelectric reservoirs generally constitute an appreciable source of methane to the atmosphere. This paper proposes simple mitigation and recovery procedures to substantially reduce atmospheric methane emissions from hydroelectric reservoirs. We aim at transforming existing methane stocks of tropical reservoirs into a clean, renewable energy source. The recovered gas methane may be pumped to large consuming centers, stocked locally and burned in gas turbines to generate electricity during high demand periods, or even purified for transport applications. Our simulations show that the use of biogenic methane may increase considerably the energy supply in countries like Brazil. As a result, it would be possible to reduce the need of additional hydroelectric dams, protecting important pristine biomes, and avoiding the resettlement of villages and indigenous reserves.

    Environmental effects occur at the dam or reservoir site, upstream and downstream of the project area during and after the completion of any hydropower project. The environmental factors also have either positive or negative cost impact on the production of hydropower. Various factors which require careful consideration while undertaking hydropower projects are: land losses, resettlement, flora and fauna, fish and aquatic life, water quality, proliferation of weeds, loss of vegetation, erosion, downstream damage and induced seismicity. After identifying the factors relevant to a hydropower project, the necessary adjustments should be made in the location and design of the project. (M.G.B.)

    A study was made for the purpose of electrification of unelectrified zones of the mountainous areas in developing countries using extremely small hydroelectric power facilities. The target for this project is a development of a micro hydroelectric power system with a size of about 5kW, which is estimated regarding that 1 village has 80 houses and each house needs electricity of 60W. In the study, the low-head system using a weir of irrigation channels in Subang pref. of West Java state was selected by the evaluation of access, stability of flow rate, natural conditions, etc. The hydroelectric power plant is of a flow-in method in which water is taken from the left bank and is injected/discharged to the downstream of the left bank. As the hybrid complementary power source, hybrid battery with a two-hour charging time at peak and a capacity of 3.5kWh was considered. When estimating the construction cost of the hybrid micro hydroelectric power system and equalizing by durable years, the operational cost per kW is 15 times higher than the benefits which local people receive. It was judged to be difficult to say that the micro hydroelectric power system is economically feasible. It was predicted that the financial profit during the demonstrative test is good, according to a trial calculation of income from power rates and the operational cost. 18 refs., 90 figs., 53 tabs.

  12. Enlarging the underground hydroelectric plant at Villarino, Spain

    Energy Technology Data Exchange (ETDEWEB)

    Oriard, L.L.

    1997-05-01

    Near the village of Villarino de los Aires, in the province of Salamanca, Spain, was an existing underground hydroelectric power plant. A major enlargement was undertaken to increase the electrical generating capacity, under a contract awarded to a joint venture of Dragados y Construcciones, S. A. (Spain), Entrecanales y Tavora, S. A. (Spain), and S.A. Conrad Zschokke (Switzerland). The enlargement required the excavation of a large and complex underground system of tunnels, shafts and chambers adjacent to existing facilities and interconnected with these facilities. The existing machine hall and transformer chamber were both extended, requiring the blasting of the existing end walls. The drilling, blasting and excavating of the underground system had to be done without damage to existing underground chambers and tunnels, or any of the existing structures, equipment or instrumentation facilities, often within just a few feet of the blasting. This required careful control of vibrations, airblast overpressures and dust. Because the only available non-electric detonating systems were found to be unreliable and unsafe, electric systems would be preferred if they could be used in a safe manner at this site. High electrical potentials existed at the site, and the facilities could not be shut down. Electrical fields were studied carefully, both in the underground environment and above the ground surface. Based on these results, it was concluded that electric detonators could be used if special blasting procedures were developed and followed. In accord with contracting practices of this Spanish agency, the contract was not awarded to the lowest bidder, but to the bidder who demonstrated the best understanding of the project and who presented the best technical proposal for conducting the work to a conclusion that would be satisfactory to the owner. The development of the technical proposal was a two-month effort for a technical group and support staff, prepared in Madrid.

    CRONOANTAR brings together researchers from Spain, Portugal, France and United Kingdom with the objective of spatially and temporally reconstruct the deglaciation process at the two largest islands in the South Shetlands Archipelago (Maritime Antarctica), since the Global Last Glacial Maximum. Glacier retreat in polar areas has major implications at a local, regional and even planetary scale. Global average sea level rise is the most obvious and socio-economically relevant, but there are others such as the arrival of new fauna to deglaciated areas, plant colonisation or permafrost formation and degradation. This project will study the ice-free areas in Byers and Hurd peninsulas (Livingston Island) and Fildes and Potter peninsulas (King George Island). Ice-cap glacier retreat chronology will be revealed by the use of cosmogenic isotopes (mainly 36Cl) on glacially originated sedimentary and erosive records. Cosmogenic dating will be complemented by other dating methods (C14 and OSL), which will permit the validation of these methods in regions with cold-based glaciers. Given the geomorphological evidences and the obtained ages, a deglaciation calendar will be proposed and we will use a GIS methodology to reconstruct the glacier extent and the ice thickness. The results emerging from this project will allow to assess whether the high glacier retreat rates observed during the last decades were registered in the past, or if they are conversely the consequence (and evidence) of the Global Change in Antarctica.

    The Deep Propagating Gravity Wave Experiment (DEEPWAVE) project was conducted over New Zealand and the surrounding regions during June and July 2014, to more fully understand the generation, propagation, and effects of atmospheric gravity waves. A large suite of instruments collected data from the ground to the upper atmosphere (~100 km), with several new remote-sensing instruments operating on board the NSF Gulfstream V (GV) research aircraft, which was the central measurement platform of the project. On 14 July, during one of the research flights (research flight 23), a spectacular event was observed as the GV flew in the lee of the sub-Antarctic Auckland Islands (50.7°S). An apparent "ship wave" pattern was imaged in the OH layer (at ~83.5 km) by the Utah State University Advanced Mesospheric Temperature Mapper and evolved significantly over four successive passes spanning more than 4 h. The waves were associated with orographic forcing generated by relatively strong (15-20 m/s) near-surface wind flowing over the rugged island topography. The mountain wave had an amplitude T' ~ 10 K, a dominant horizontal wavelength ~40 km, achieved a momentum flux exceeding 300 m2 s-2, and eventually exhibited instability and breaking at the OH altitude. This case of deep mountain wave propagation demonstrates the potential for strong responses in the mesosphere arising from a small source under suitable propagation conditions and suggests that such cases may be more common than previously believed.

    1993-11-01

    The social impact that large-scale hydro-electric development has on the Cree of James Bay following the construction of the La Grande Complex was discussed. Many environmental changes were brought about by dam construction. The project, which also involved the first settlement (the James Bay and Northern Quebec Agreement) directed at extinguishing aboriginal title to land and natural resources in Canada, resulted in several relocations of Cree communities. In addition to compensation, the Agreement included a formal procedure for environmental and social impact assessment for development projects. However, there was little commitment, as a matter of corporate or government policy, to monitoring any of the social impacts. This paper is a preliminary response to an appeal for attention to be focused on the social consequences of hydro-electric development for the Cree in James Bay. Data from social service files indicate that the rapid centralization of the James Bay Cree into structured communities led to social instability in the villages, reflected by high frequencies in suicide, neglect of children, vandalism and drug and alcohol abuse. The material presented here is expected to serve as a warning that in further developing the far North of Quebec the pace of social change in Cree society will have to be slowed down to avoid social destruction of the native communities. 15 refs., 2 tabs.

    Full Text Available Marginal erosions in reservoirs of hydroelectric plants have caused economic and environmental problems concerning hydroelectric power generation, reduction of productive areas and devaluing land parcels. The real extension and dynamics of these erosion processes are not well known for Brazilian reservoirs. To objectively assess these problems Unesp (Univ Estadual Paulista and Duke Energy are developing a joint project which aims at the monitoring the progression of some erosive processes and understanding the causes and the dynamics of this phenomenon. Mobile LASER scanning was considered the most suitable alternative for the challenges established in the project requirements. A MDL DynaScan Mobile LASER M150 scanner was selected which uses RTK for real time positioning integrated to an IMU, enabling instantaneous generation of georeferenced point clouds. Two different reservoirs were choose for monitoring: Chavantes (storage plant and Rosana (run-of-river plant, both in the Paranapanema River, border of São Paulo and Paraná States, Brazil. The monitoring areas are scanned quarterly and analysed with base on the point cloud, meshes, contours and cross sections. Cross sections are used to visualize and compute the rate and the dynamics of erosion. Some examples and quantitative results are presented along with an analysis of the proposed technique. Some recommendations to improve the field work and latter data processing are also introduced.

    Full Text Available Hydroelectric power plants are considered strategic for the country when considering their relevance and impact on other sectors of the economy. However, the dynamics of the operation of a plant, its support structure and power generation activities can cause impacts on the environment, which must be constantly monitored in order to mitigate any environmental risks. The purpose of this study is to examine the partnership relations between a plant by menas of the creation of a department within the environmental management and universities and research institutes to identify specific partnerships in environmental management and hydroelectric plants. Six projects have been selected for analysis, four of them related to projects with universities and two related to cooperation with research institutes. The focus of the analysis was restricted to the main points observed in the management of these partnerships, which are: (a motivation for establishing partnerships, (b the composition of the estimated costs for implementing these partnerships, (c the difficulties of reconciling technical management and financial management, and (d the measurement of results and contributions from these interactions. Administrative practices of management of partnerships were also analyzed in the stages preceding cooperation for cooperation and further cooperation. Although other such studies are needed to strengthen the findings presented, one can conclude that the purposes of the establishment of cooperation in environmental management differ from those observed in other fields of knowledge such as engineering and biotechnology, for example.

    The Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project represents an integration of research methodology into a community-based outpatient practice affiliated with an academic medical centre. The MIDAS project is the largest clinical epidemiological study using semi-structured interviews to assess a wide range of psychiatric disorders in a general clinical outpatient practice. In an early report from the MIDAS project, we found that across diagnostic categories clinicians using unstandardized, unstructured clinical interviews underrecognized diagnostic comorbidity, compared with the results of semi-structured interviews. Moreover, we found that the patients often wanted treatment for symptoms of disorders that were diagnosed as comorbid, rather than principal, conditions. This highlighted the importance, from the patient's perspective, of conducting thorough diagnostic interviews to diagnose disorders that are not related to the patient's chief complaint because patients often desire treatment for these additional diagnoses. While several of the initial papers from the MIDAS project identified problems with the detection of comorbid disorders in clinical practice, regarding the diagnosis of bipolar disorder we observed the emergence of an opposite phenomenon-clinician overdiagnosis. The results from the MIDAS project, along with other studies of diagnosis in routine clinical practice, have brought to the forefront the problem with diagnosis in routine clinical practice. An important question is what do these findings suggest about the community standard of care in making psychiatric diagnoses, and whether and how the standard of care should be changed? The implications are discussed. © The Author(s) 2016.

    Kamehameha Schools, in conjunction with several federal, state, and private organizations, has proposed to conduct conservation management on approximately 5,340 ha (~13,200 acres) of land they own in the vicinity of Kīpukalupea in the North Kona District on the island of Hawai'i. The goal of this program is to restore and enhance the habitat to benefit native plant and animal populations that are currently, or were formerly, found in this site. The initial phase of this project has been focused on various activities including conducting baseline surveys for bird and plant species so Kamehameha Schools could develop a Safe Harbor Agreement (SHA) for the proposed project lands relative to the habitat management and species reintroduction efforts they would like to conduct in the Lupea Project area. This report summarizes methods that were used to collect field data on plant species and communities within the project area, and the results of that initial survey. The information was used to calculate baseline values for all listed threatened or endangered plant species found, or expected to be found, within the project area, and to design a monitoring program to assess changes in plant communities and rare plant species relative to management activities over the duration of the SHA.

  7. Implicit environmental costs in hydroelectric development

    1992-01-01

    The ranking of hydropower projects under the Norwegian Master Plan for Water Resources is used to derive implicit government preferences for a number of environmental attributes described by ordinal scores for each project. Higher negative scores are generally associated with greater implicit willingness to pay to avoid the environmental damage tied to the attribute, caused by hydropower development. The total (ordinary economic and implicit environmental) cost for each project are derived, and the environmental costs per capacity unit are found to be on the same order as the economic costs, lower for projects ranked for early exploitation, and higher for projects to be saved permanently. An implicit long-run marginal cost curve for Norwegian hydropower development is derived, which is generally upward sloping, but not uniformly so. This can be due to the model specification problems or ranking inconsistencies, both of which are likely to be present. 11 refs., 7 figs., 1 tab

    1999-05-01

    A final application was submitted in March 1998 by Canadian Hydro Developers (CHD) with the intent of obtaining a Project Approval certificate under the Act for development of the Project. The purpose of the project committee report is to summarize the application and project report, to describe the potential environmental, economic, social, cultural, heritage and health effects of the project and measures required to mitigate significant adverse effects and to document the recommendations of the committee. The Project is composed of five main parts including the headworks, tunnel, penstock, powerhouse and transmission line. The potential environmental effects of the Project relate mainly to fisheries resources including entrainment at the intake, instream flow needs downstream from the headworks, alteration of fish habitat, sedimentation, and blockage of fish passage. CHD expects to minimize these effects through facility design modifications, operational changes and monitoring programs as required. Other concerns such as alteration of creek temperature, generation of methyl mercury in reservoirs, greenhouse gas flux in reservoirs and total gas pressures have been examined in light of the Project's size and operational schenarios, and the proponent expects these effects to be of minor concern. The Project Committee concluded that the project, with successful implementation and compliance of mitigation and compensation strategies, is not expected to cause significant adverse effects

    2014-03-01

    While only about 30% of California's usable water storage capacity lies at higher elevations, high-elevation (above 300 m) hydropower units generate, on average, 74% of California's in-state hydroelectricity. In general, high-elevation plants have small man-made reservoirs and rely mainly on snowpack. Their low built-in storage capacity is a concern with regard to climate warming. Snowmelt is expected to shift to earlier in the year, and the system may not be able to store sufficient water for release in high-demand periods. Previous studies have explored the climate warming effects on California's high-elevation hydropower by focusing on the supply side (exploring the effects of hydrological changes on generation and revenues) ignoring the warming effects on hydroelectricity demand and pricing. This study extends the previous work by simultaneous consideration of climate change effects on high-elevation hydropower supply and pricing in California. The California's Energy-Based Hydropower Optimization Model (EBHOM 2.0) is applied to evaluate the adaptability of California's high-elevation hydropower system to climate warming, considering the warming effects on hydroelectricity supply and pricing. The model's results relative to energy generation, energy spills, reservoir energy storage, and average shadow prices of energy generation and storage capacity expansion are examined and discussed. These results are compared with previous studies to emphasize the need to consider climate change effects on hydroelectricity demand and pricing when exploring the effects of climate change on hydropower operations.

    Elderly populations are disproportionately affected by disasters. In part, this is true because for many older adults, special assistance is needed to mitigate the consequences of disasters on their health and wellbeing. In addition, many older adults may reside in diverse living complexes such as long-term care facilities, assisted living facilities and independent-living senior housing complexes. Planning for each type of facility is different and the unique features of these facilities must be considered to develop readiness to deal with disasters. Based on this, the Rhode Island Department of Health established the Senior Resiliency Project to bolster the level of resiliency for the types of living facilities housing older adults. The project involves performing onsite assessments of energy resources, developing site-specific sheltering-inplace and energy resiliency plans, and educating and training facility employees and residents on these plans and steps they can take to be better prepared. Based on the feasibility of conducting these activities within a variety of facilities housing older adults, the project is segmented into three phases. This paper describes survey findings, outcomes of interventions, challenges and recommendations for bridging gaps observed in phases 1 and 2 of the project.

    The increasing energy challenges faced, in particular, by isolated communities, such as insular communities, call for an integrated, flexible and easy-to-apply methodology aiming at providing a list of renewable energy sources) (RES) projects capable to reduce green house gas (GHG) emissions, satisfy future energy forecasts and reach the objectives of international/national energy directives and obligations, as, for example, the ones set by the Kyoto Protocol by 2010. The EU project EMERGENCE 2010 developed such a methodology that is implemented here in the case study of wind parks in the Dodecanese islands in Greece. The results obtained consist of a final list of financially viable RES wind projects, for which various barriers have been previously identified and assessed. The additional advantages of the proposed methodology is that besides providing as an end result a comprehensive list of RES projects adopted to specific criteria and regional priorities, it also allows space for involving - from early stages - the local community and stakeholders in the decision-making process (participatory planning); in this way, the EMERGENCE 2010 methodology may assist towards the RES promotion and public acceptance, the profitability of RES investments and the regional sustainable development.

    shown a large variation in the data on greenhouse gas emissions, which would suggest that more care, should be taken in the choice of future projects by the Brazilian electrical sector. The emission of CH4 by hydroelectric reservoirs is always unfavorable, since even if the carbon has originated with natural sources, it is part of a gas with higher GWP in the final calculation. Emissions of CO2 can be attributed in part to the natural carbon cycle between the atmosphere and the water of the reservoir. Another part could be attributed to the decomposition of organic material, caused by the hydroelectric dam.

    Since 1992, Bayernwerk AG has been operating a solar island network at Flanitzhuette in the Bavarian Forest, to supply a remote hamlet. The plant is based on a photo-electric system together with a battery and a gas unit. The plant was designed by the least cost planning (LCP) process, ie: The electricity demand was first reduced by economy measures on the customers` side (demand side management, DSM) and then largely coverd by photo-electric supply. In the case of the `Flanitzhuette solar island`, the application of LCP was able to contribute to minimising the supply costs. The authors report on the project and the results in the electricity generation and saving areas. (orig.)

    The DEEPWAVE project recently took place in New Zealand during the months of June and July 2014. This international program focused on investigating the generation and deep propagation of atmospheric gravity waves. A series of instruments was operated at several ground-based locations and on-board the NSF Gulfstream V aircraft. 26 research flights were performed to explore possible wave sources and their effects on the middle and upper atmosphere. On July 14th, a research flight was conducted over the Auckland Islands, a small sub Antarctic archipelago located ~450km south of New Zealand. Moderate southwesterly tropospheric wind (~25m/s) was blowing over the rugged topography of the islands, generating mountain wave signature at the flight altitude. Spectacular small-scale gravity waves were simultaneously observed at the mesopause level using the USU Advanced Mesospheric Temperature Mapper (AMTM). Their similarity with the model-predicted waves was striking. This presentation will describe this remarkable case of deep wave propagation and compare the measurements obtained with the instruments on-board the aircraft with forecasting and wave propagation models.

  1. A summary of water chemistry changes following hydroelectric development in northern Manitoba, Canada

    Williamson, D.A.; Ralley, W.E.

    1993-01-01

    A detailed summary is provided from five major water quality studies undertaken in northern Manitoba to assess the effects of hydroelectric projects on water quality. Physical changes occurring with the area affected by both the Churchill River diversion and Lake Winnipeg regulation have led to water quality changes in many cases. Phosphorus appeared to increase at some sites while decreasing at others, reflecting a new balance between erosion of new P sources and later uptake or deposition. Color declined at all sites except at Red Head Rapids. Turbidity increased in Southern Indian Lake and in the Burntwood River at Thompson in response to the Churchill diversion, but turbidity has historically exceeded drinking water quality objectives. It is unclear whether the observed changes in water chemistry may have the potential to directly impact aquatic life and wildlife. A major limitation of the water quality data set is the lack of pre-development data for many of the trace elements analyzed. Relative to an upstream reference site, concentrations of Cu, Pb, and Zn were slightly higher at some sites affected by hydroelectric development, but it is not known whether this condition existed prior to development. Exceedances of water quality objectives for some trace elements occurred intermittently at some sites but it is not possible to determine whether these exceedances occurred infrequently historically as a result of natural variability. 34 refs., 1 fig., 13 tabs

  2. Mines as lower reservoir of an UPSH (Underground Pumping Storage Hydroelectricity): groundwater impacts and feasibility

    2016-04-01

    The energy framework is currently characterized by an expanding use of renewable sources. However, their intermittence could not afford a stable production according to the energy demand. Pumped Storage Hydroelectricity (PSH) is an efficient possibility to store and release electricity according to the demand needs. Because of the topographic and environmental constraints of classical PSH, new potential suitable sites are rare in countries whose topography is weak or with a high population density. Nevertheless, an innovative alternative is to construct Underground Pumped Storage Hydroelectricity (UPSH) plants by using old underground mine works as lower reservoir. In that configuration, large amount of pumped or injected water in the underground cavities would impact the groundwater system. A representative UPSH facility is used to numerically determine the interactions with surrounding aquifers Different scenarios with varying parameters (hydrogeological and lower reservoir characteristics, boundaries conditions and pumping/injection time-sequence) are computed. Analysis of the computed piezometric heads around the reservoir allows assessing the magnitude of aquifer response and the required time to achieve a mean pseudo-steady state under cyclic solicitations. The efficiency of the plant is also evaluated taking the leakage into the cavity into account. Combining these two outcomes, some criterions are identified to assess the feasibility of this type of projects within potential old mine sites from a hydrogeological point of view.

    2011-12-01

    Significant tsunamis have often affected the southwest Indian Ocean. The scientific project PREPARTOI (Prévention et REcherche pour l'Atténuation du Risque Tsunami dans l'Océan Indien), partly founded by the MAIF foundation, aims at assessing the tsunami risk on both french islands of this region, La Réunion and Mayotte. Further purpose of this project is the detailed hazard and vulnerability study for specific places of these islands, selected according to their environmental and human issues and observed impacts of past tsunamis. Tsunami hazard in this region, recently highlighted by major events in the southwest Indian Ocean, has never been thoroughly evaluated. Our study, within the PREPARTOI project, contributes to fill in this lack. It aims at examining transoceanic tsunami hazard related to earthquakes by modeling the scenarios of major historical events. We consider earthquakes with magnitude greater than Mw 7.7 located on the Sumatra (1833, 2004, 2010), Java (2006) and Makran (1945) subduction zones. First, our simulations allow us to compare the tsunami impact at regional scale according to the seismic sources; we thus identify earthquakes locations which most affect the islands and describe the impact distribution along their coastline. In general, we note that, for the same magnitude, events coming from the southern part of Sumatra subduction zone induce a larger impact than the north events. The studied tsunamis initiated along the Java and Makran subduction zones have limited effects on both French islands. Then, detailed models for the selected sites are performed based on high resolution bathymetric and topographic data; they provide estimations of the water currents, the water heights and the potential inundations. When available, field measurements and maregraphic records allow testing our models. Arrival time, amplitude of the first wave and impact on the tide gauge time series are well reproduced. Models are consistent with the observations

    By their dimensions hydroelectric constructions constitute one of the evident examples of man's action upon nature, with favorable as well as unfavorable effects. By using past experience, such effects can be correctly establish and evaluated both by specialists from different fields and by representatives of the local population. The paper proposes several criteria for qualitative characterization of such effects. Some favorable and unfavorable effects of dams, lakes, secondary catchment and derivations are discussed. Also, having in view the water flow distribution which would allow a normal insertion of such construction in the environment, despite of some power production diminish diminishing, two proposals are made concerning possible solutions for secondary catchment and the hydroelectric power stations situated in the upper zones of the rivers.

    International Nuclear Information System (INIS)

    Rosa, L.P.; Schaeffer, R.; Santos, M.A.

    1996-01-01

    A recent paper by Fearnside points out that hydroelectric development in Amazonia is a significant source of greenhouse gases (GHG) emissions. This conclusion is in contrast to the common belief that hydroelectric dams are better than fossil fuel use in electric power generation, from the view point of GHG emissions. The authors have considered both CH 4 and CO 2 emissions taking into account the instantaneous radiative forcing due to a unit increase in the concentration of gases, the decay times of gases in the atmosphere and the emissions patterns of emissions vary depending on biomass density and type of the forest area flooded, as well as on depth of flooding. As the Fearnside paper is more concerned with CO 2 emissions from the above water biomass, the authors' focus will be restricted to the formulae for calculating the cumulative effect of CO 2

    Urban regions are often impacted more by heat than adjacent rural areas, which is a phenomenon known as the urban heat island (UHI) effect. Urban areas are also highly heterogeneous and notoriously difficult to monitor using standard meteorological protocols—the hottest microclimates within a city often occur in locations that lack open, representative installation sites that are an adequate distance from buildings and direct heat sources. To investigate the challenges of monitoring urban heat, this study examines the sensitivity of temperature and humidity sensors currently used in a Baltimore UHI monitoring network to differences in sun exposure, material on which the data collecting instrument is attached, and land cover class of the vicinity. Sensitivity to sun exposure and attachment site can be interpreted as sources of uncertainty for urban heat monitoring, while sensitivity to land cover may reflect a true source of local temperature and humidity variability. In this study, we present results from a test deployment designed to assess the sensitivity of heat measurements to each of these three factors. We then apply these results to interpret measurements taken across the entire Baltimore UHI monitoring network. These results can then be used to improve heat measurements and more accurately represent and quantify the UHI effect on a broader scale, such as in neighborhoods or urban centers.

  17. Cross currents : hydroelectricity and the engineering of northern Ontario

    Energy Technology Data Exchange (ETDEWEB)

    Manore, J.L. [Calgary Univ., AB (Canada)

    1999-05-01

    The history of hydroelectric development in northern Ontario was reviewed and analysed with special emphasis on the developments along the Mattagami and Abitibi Rivers. The objective was to examine the important factors that shaped modern hydroelectric development in Canada. System builders, the privately owned Nesbitt Thomson Company, the publicly owned Hydro Electric Power Corporation of Ontario and the eventual evolution of the single power system under Ontario Hydro are chronicled. Broad historical themes such as the technological impacts, regionalism, indigenous rights, plus environmental and economic issues are examined, in addition to an appreciation of the importance of electricity in the manufacturing sector of Ontario, the impact of hydroelectric development on the northern environment and on the northern First Nations, who rely on rivers for their subsistence. Until fairly recently, government policies and interpretations of law often excluded the recognition of Aboriginal uses of river systems, thereby limiting First Nations` peoples ability to practice traditional ways of life. In essence, the book is an account of how the northeastern power system in Ontario shaped the social, political and natural environments and how the development of northeastern power sources by southern power developers shaped the regional interactions between Ontario`s north and south. refs., figs.

    One of the great environmental advantage offered by hydro-electricity in northern or temperate climates includes reduced atmospheric emissions. While natural gas plants, from an environmental viewpoint, are thought to be the best fossil fuel option, they emit 18 times more greenhouse gases, at least 60 times more sulfur dioxide and hundreds of times more nitrogen oxides than do hydro-electric systems. The relative SO 2 and greenhouse gas emissions from energy systems in Canada were outlined, and their environmental impacts were described. At the same time, mention was made of other environmental pollutants, such as acid rain, photochemical smog, and particulates that continue to have major impacts on the environment, but were displaced as the focus of attention by greenhouse gases. A study was conducted to determine the effects of extreme biomass decomposition and greenhouse gas emissions from reservoirs. The study showed that at depths of more than 10 centimeters below water surface, organic matter does not contribute to greenhouse gas production, even at 20 degrees C. It was demonstrated that even when maximum biomass decomposition is assumed, a modern natural gas plant would emit 14 times more green house gases than a hydroelectric plant of comparable capacity. 13 refs., 4 tabs., 3 figs

    Emitted by fires, black carbon aerosols (rBC) perturb the atmosphere's physical and chemical properties and are climatically active. Sedimentary charcoal and other paleo-fire records suggest that rBC emissions have varied significantly in the past due to human activity and climate variability. However, few paleo rBC records exist to constrain reconstructions of the past rBC atmospheric distribution and its climate interaction. As part of the international Roosevelt Island Climate Evolution (RICE) project, we have developed an Antarctic rBC ice core record spanning the past ~65 Kyr. The RICE deep ice core was drilled from the Roosevelt Island ice dome in West Antarctica from 2011 to 2013. The high depth resolution (~ 1 cm) record was developed using a single particle intracavity laser-induced incandescence soot photometer (SP2) coupled to an ice core melter system. The rBC record displays sub-annual variability consistent with both austral dry-season and summer biomass burning. The record exhibits significant decadal to millennial-scale variability consistent with known changes in climate. Glacial rBC concentrations were much lower than Holocene concentrations with the exception of several periods of abrupt increases in rBC. The transition from glacial to interglacial rBC concentrations occurred over a much longer time relative to other ice core climate proxies such as water isotopes and suggests . The protracted increase in rBC during the transition may reflected Southern hemisphere ecosystem / fire regime changes in response to hydroclimate and human activity.

    The Long Island Solar Farm (LISF) is a remarkable success story, whereby very different interest groups found a way to capitalize on unusual circumstances to develop a mutually beneficial source of renewable energy. The uniqueness of the circumstances that were necessary to develop the Long Island Solar Farm make it very difficult to replicate. The project is, however, an unparalleled resource for solar energy research, which will greatly inform large-scale PV solar development in the East. Lastly, the LISF is a superb model for the process by which the project developed and the innovation and leadership shown by the different players.

    Representative systematic evaluation studies of the workspace and the extent to which that space is suitable for performing tasks have been developed by professionals engaged on finding evidence as to the importance of users and designers being joint participants in drawing up projects. In this context, this paper sets out to evaluate the environment of a control room in the hydroelectric sector, based on a multidisciplinary method which integrates ergonomics, architecture and environmental psychology so as to assess the influence of space on the user, and thus to identify the user's level of satisfaction with it. It was observed that some adaptation strategies of the space for activities were not implemented satisfactorily, resulting in the need for further studies on making workspaces suitable.

    2000-01-01

    Special design features required in constructing a 2444 m long dyke on the north bank of the La Grade River at the site of the La Grande 1 hydroelectric power project are described. The special features involved construction of a downstream bank and upstream stabilization berms to avoid the occurrence of potentially dangerous retrogressive slides. These special features were deemed essential due to the presence of sensitive marine clay, covered with deltaic sand and silt and river sand deposits. The paper highlights the geotechnical and hydrogeological conditions of the northern terrace, and describes the different construction phases of stabilizing the river bank. Control of groundwater pressures in the lower aquifer with relief wells is emphasized. 9 refs., 1 tab., 17 figs

    1996-01-01

    The aim of this study was to test the effectiveness of an underwater acoustic barrier as a means of preventing the entry of salmon (Salmo salar) and sea trout (Salmo trutta) smolts and other fish into the water intake of a hydro-electric power (HEP) station. A secondary objective was to measure the injury rate of fish passed through the turbine, so that the risk to any fish that penetrated the acoustic barrier could also be determined. The test site, which was a 575kW Kaplan plant located at Blantyre on the R. Clyde, Lanarkshire, was selected as being representative of run-of-river sites currently being developed under the Government's NFFO (Non-Fossil Fuel Obligation) and SRO (Scottish Renewables Order) schemes. A further objective was to disseminate information arising from the project to the scientific and HEP community. (author)

  5. Will initiatives to promote hydroelectricity consumption be effective? Evidence from univariate and panel LM unit root tests with structural breaks

    International Nuclear Information System (INIS)

    Lean, Hooi Hooi; Smyth, Russell

    2014-01-01

    This paper examines whether initiatives to promote hydroelectricity consumption are likely to be effective by applying univariate and panel Lagrange Multiplier (LM) unit root tests to hydroelectricity consumption in 55 countries over the period 1965–2011. We find that for the panel, as well as about four-fifths of individual countries, that hydroelectricity consumption is stationary. This result implies that shocks to hydroelectricity consumption in most countries will only result in temporary deviations from the long-run growth path. An important consequence of this finding is that initiatives designed to have permanent positive effects on hydroelectricity consumption, such as large-scale dam construction, are unlikely to be effective in increasing the share of hydroelectricity, relative to consumption of fossil fuels. - Highlights: • Applies unit root tests to hydroelectricity consumption. • Hydroelectricity consumption is stationary. • Shocks to hydroelectricity consumption result in temporary deviations from the long-run growth path

    The use of water wasted in hydroelectric plants as normalization dam excess, which constitute a hydrodynamic potential useful to generate electric energy which can be subsequently used to produce hydrogen and its subsequent consumption in fuel cells has been considered as an alternative for hydraulic energy-rich countries like Brazil. The case is examined in which all the water wasted in the hydroelectric plants, spilled by dam gates to maintain acceptable water levels, from the 3 largest Brazilian hydroelectric plants was used to produce hydrogen. During the year of 2008, the electric energy produced from this utilization would have been equivalent to 52.8 TWh, an amount that corresponds to an increase of ca. 15% of the total electric energy produced in the country. Furthermore, if this amount of hydrogen was used in the replacement of internal combustion vehicles by fuel cells, this would have prevented the production of 2.26 x 10{sup 7} ton of Co{sub 2} per year. This plan would also significantly decrease production and release of greenhouse gases. (author)

    Artificial reefs are often discouraged in shallow waters over concerns of storm damage to structures and surrounding habitat. Biorock coral reef restoration projects were initiated in waters around 5 m deep in Grand Turk, at Oasis (October 2006) and at Governor's Beach (November 2007). Hemi-cylindrical steel modules, 6m long were used, four modules at Oasis and six at Governor's Beach. Each project has over 1200 corals transplanted from sites with high sedimentation damage, and are regularly monitored for coral growth, mortality and fish populations. Corals show immediate growth over wires used to attach corals. Growth has been measured from photographs using a software program and is faster at Governor's Beach. After hurricanes Hanna and Ike (September 2008) the Governor's Beach structure was fully standing since the waves passed straight through with little damage, the Oasis structures which were tie-wired rather than welded had one module collapse (since been replaced with a new, welded structure). Hurricane Ike was the strongest hurricane on record to hit Grand Turk. Most cables were replaced following the hurricanes due to damage from debris and high wave action. The projects lost about a third of the corals due to hurricanes. Most of those lost had only been wired a few days before and had not yet attached themselves firmly. These projects have regenerated corals and fish populations in areas of barren sand or bedrock and are now attractive to snorkelers. High coral survival and low structural damage after hurricanes indicate that Biorock reef restoration can be effective in storm-impacted areas.

    By the end of this century higher temperatures and significantly reduced rainfall are projected for the Brazilian North and Northeast (NE) regions due to Global Warming. This study examines the impact of these long-term rainfall changes on the Brazilian Northeast's hydroelectric production. Various studies that use different IPCC models are examined in order to determine the average rainfall reduction by the year 2100 in comparison to baseline data from the end of the 20th century. It was found that average annual rainfall in the NE region could decrease by approximately 25-50% depending on the emissions scenario. Analysis of historical rainfall data in the São Francisco basin during the last 57years already shows a decline of more than 25% from the 1961-90 long-term average. Moreover, average annual rainfall in the basin has been below its long-term average every year bar one since 1992. If this declining trend continues, rainfall reduction in the basin could be even more severe than the most pessimistic model projections. That is, the marked drop in average rainfall projected for 2100, based on the IPCC high emissions scenario, could actually eventuate before 2050. Due to the elasticity factor between rainfall and streamflow and because of increased amounts of irrigation in the São Francisco basin, the reduction in the NE's average hydroelectric production in the coming decades could be double the predicted decline in rainfall. Conversely, it is estimated that wind power potential in the Brazilian NE will increase substantially by 2100. Therefore both wind and solar power will need to be significantly exploited in order for the NE region to sustainably replace lost hydroelectric production. Copyright © 2018 Elsevier B.V.

    Entomological studies conducted in large hydroelectric infrastructure projects are a tool for the prevention and control of vector-borne diseases. These diseases emerge as a consequence of changes made to the terrain that often increase the natural and artificial mosquito larval habitats. Many of these insects are of public health importance and population increases result in an increased risk of disease transmission. The culicine (mosquito) and phlebotomine (sand fly) populations were characterized in the area of the Porce II and Porce III hydroelectric projects of Antioquia between 1990 to 2009. Periodical entomological samplings were made in the area of impact, in the workers camps, and construction sites. Adult specimens were captured with nets, Shannon light traps, CDC light traps, and protected human bait. Mosquito larvae of the following species were identified: Culex coronator, Culex nigripalpus, Culex corniger, Culex quinquefasciatus and Limatus durhami. The most frequently identifiers of larval habitats were low tanks, waste cans, tires, and aquatic plants. Aedes aegypti specimens were captured in only two rural locations from two municipalities within the area of influence. Specimens from the following mosquito genera were captured in forest areas: Aedes, Mansonia, Culex, Psorophora, Wyeomyia, Phonyomyia, Uranotaenia, Haemagogus and Sabethes. The most important mosquito found was Haemogogus janthinomis, an efficient yellow fever vector in Colombia. The area has been endemic for leishmaniasis and in the current study, 20 species of Lutzomyia sand flies, potential vectors, were identified. Among malaria vectors, the most important species found in the area were Anopheles nuneztovari and Anopheles pseudopunctipennis. A wide variety of vectors were discovered in the area of the Porce II and Porce III hydroelectric projects, and many of these were relevant for public health. Further monitoring will be necessary to minimize disease transmission risks among the

  11. Potential effects of the Hawaii Geothermal Project on ground-water resources on the island of Hawaii

    In 1990, the State of Hawaii proposed the Hawaii Geothermal Project for the development of as much as 500 MW of electric power from the geothermal system in the East Rift Zone of Kilauea Volcano. This report uses data from 31 wells and 8 springs to describe the properties of the ground-water system in and adjacent to the East Rift Zone. Potential effects of this project on ground-water resources are also discussed. Data show differences in ground-water chemistry and heads within the study area that appear to be related to mixing of waters of different origins and ground-water impoundment by volcanic dikes. East of Pahoa, the ground-water system within the rift is highly transmissive and receives abundant recharge from precipitation; therefore, the pumping of freshwater to support geothermal development in that part of the rift zone would have a minimal effect on ground-water levels. To the southwest of Pahoa, dike impoundment reduces the transmissivity of the ground-water system to such an extent that wells might not be capable of supplying sufficient fresh water to support geothermal operations. Contamination of ground-water resources by accidental release of geothermal fluids into shallow aquifers is possible because of corrosive conditions in the geothermal wells, potential well blowouts, and high ground-water velocities in parts of the region. Hydrologic monitoring of water level, temperature, and chemistry in observation wells should continue throughout development of geothermal resources for the Hawaii Geothermal Project for early detection of leakage and migration of geothermal fluids within the groundwater system.

    1980-05-01

    The case study is an analysis of the legal, institutional, and financial incentives and obstacles to the development of the hydroelectric potential on the Goose River in Maine. The Goose River project concerns development by a private developer, Maine Hydro-Electric Development Corporation. The project is comprised of a five-dam system, with the first dam located at Swan Lake and the fifth dam about one mile from the sea. It will utilize the 7500 acre-feet of storage capacity of Swan Lake to run the four downstream power stations. The system is designed to generate 430 kWs of total capacity which would be sold to Central Maine Power, the local investor-owned public utility.

    The driving force behind the Integrated Energy Mapping and Analysis project was the identification and analysis of a suite of pathways that the Cowichan Valley Regional District (CVRD) can utilise to increase its energy resilience, as well as reduce energy consumption and GHG emissions, with a primary focus on the residential sector. Mapping and analysis undertaken will support provincial energy and GHG reduction targets, and the suite of pathways outlined will address a CVRD internal target that calls for 75% of the region's energy within the residential sector to come from locally sourced renewables by 2050. The target has been developed as a mechanism to meet resilience and climate action target. The maps and findings produced are to be integrated as part of a regional policy framework currently under development. Task 5 focused on energy projection mapping to estimate and visualise the energy consumption density and GHG emissions under different scenarios. The scenarios from task 4 were built around the energy consumption density of the residential sector under future land use patterns and rely on different energy source combinations (the suite of pathways). In task 5 the energy usage under the different scenarios were fed back into GIS, thereby giving a visual representation of forecasted residential energy consumption per unit area. The methodology is identical to that used in task 2 where current usage was mapped, whereas the mapping in this task is for future forecasts. These results are documented in this report. In addition, GHG mapping under the various scenarios was also undertaken. (LN)

    Coastal ecosystem management typically relies on subjective interpretation of scientific understanding, with limited methods for explicitly incorporating process knowledge into decisions that must meet multiple, potentially competing stakeholder objectives. Conversely, the scientific community lacks methods for identifying which advancements in system understanding would have the highest value to decision-makers. A case in point is barrier island restoration, where decision-makers lack tools to objectively use system understanding to determine how to optimally use limited contingency funds when project construction in this dynamic environment does not proceed as expected. In this study, collaborative structured decision-making (SDM) was evaluated as an approach to incorporate process understanding into mid-construction decisions and to identify priority gaps in knowledge from a management perspective. The focus was a barrier island restoration project at Ship Island, Mississippi, where sand will be used to close an extensive breach that currently divides the island. SDM was used to estimate damage that may occur during construction, and guide repair decisions within the confines of limited availability of sand and funding to minimize adverse impacts to project objectives.

Repairing minor damage immediately was determined to be generally more cost effective (depending on the longshore extent) than risking more damage to a weakened project. Key gaps in process-understanding relative to project management were identified as the relationship of island width to breach formation; the amounts of sand lost during breaching, lowering, or narrowing of the berm; the potential for minor breaches to self-heal versus developing into a major breach; and the relationship between upstream nourishment and resiliency of the berm to storms.

    Coastal ecosystem management typically relies on subjective interpretation of scientific understanding, with limited methods for explicitly incorporating process knowledge into decisions that must meet multiple, potentially competing stakeholder objectives. Conversely, the scientific community lacks methods for identifying which advancements in system understanding would have the highest value to decision-makers. A case in point is barrier island restoration, where decision-makers lack tools to objectively use system understanding to determine how to optimally use limited contingency funds when project construction in this dynamic environment does not proceed as expected. In this study, collaborative structured decision-making (SDM) was evaluated as an approach to incorporate process understanding into mid-construction decisions and to identify priority gaps in knowledge from a management perspective. The focus was a barrier island restoration project at Ship Island, Mississippi, where sand will be used to close an extensive breach that currently divides the island. SDM was used to estimate damage that may occur during construction, and guide repair decisions within the confines of limited availability of sand and funding to minimize adverse impacts to project objectives. Sand was identified as more limiting than funds, and unrepaired major breaching would negatively impact objectives. Repairing minor damage immediately was determined to be generally more cost effective (depending on the longshore extent) than risking more damage to a weakened project. Key gaps in process-understanding relative to project management were identified as the relationship of island width to breach formation; the amounts of sand lost during breaching, lowering, or narrowing of the berm; the potential for minor breaches to self-heal versus developing into a major breach; and the relationship between upstream nourishment and resiliency of the berm to storms.

    In September 1993, Russian Federation Prime Minister Chernomyrdin and United States Vice President Gore agreed on a joint study to examine options for Russia`s energy future. The objective of the study would be to develop a long-term, comprehensive program for the Russian power sector. A joint Russian-American program was established by the United States government. This program was charged to assess all aspects of the Russian energy sector, including conservation, thermal energy, nuclear energy, transmission line systems, and hydropower energy. The objective of the hydropower energy assessment aspect of the study was to prepare a time-phased investment plan for the period 1995 to 2000 for expansion of the existing hydroelectric energy production. The Hydropower Assessment Project required a close working relationship between engineers from the United States and the Russian Federation. The Project Team was given unprecedented access to design and economic data of existing and planned hydropower projects in the Russian Federation. This paper presents the methodology of the hydropower generation assessment for Russia, focusing on the partnering of American and Russian engineers, which led to a mutual transfer of technology and a successful project.

    In underground working places, especially when ventilation is not properly regulated, large amounts of natural radioactivity can be found. This can give rise to potential exposures of non-negligible magnitude. Direct measurements of gamma radiation and radon were carried out during excavation works for the construction of an hydroelectric plant in the north of Italy. After the construction of the plant, in order to reduce radon concentrations and to improve ventilation effectiveness, the main entry gate was motorized and automated. Then, in order to find the optimal speed for the fans located in the galleries and in the power plant, radon and airflow velocity were measured. Correlation data between airflow and radon concentrations were found. An automatic regulation system has been set up using air velocity detectors and slightly modifying the software for the control and regulation of the power plant. Measurements must be made in order to identify radon sources and evaluate quantitative contributions as a function of ventilation. Underground hydroelectric plants are provided with entry galleries as well as secondary galleries from which radon coming out from the soil and the walls can exhale in quantities that depend on the contents of 226 Ra in the rocks and in the building materials. Other radon sources are the water coming out from the walls of the galleries and the water in the deep well located at the bottom of the power plant. Geological studies and mathematical models are useful means for the analysis of the relative contributions of the main sources as well as for the prediction of the effects deriving from modifications of the hydroelectric plant ventilation system or resulting from other important structural changes.

  8. Renewable energy islands in Europe

    Oestergaard, Iben [ed.

    1998-12-31

    This publication includes a compiled presentation of various aspects concerning the possible transformation of some European islands into renewable energy communities and these projects were presented by a selection of pioneer islands at the first European Seminar on Renewable Energy Islands, held on the Danish island of Samsoee, 29-30 June 1998. This issue has increased in importance with the presentation of the ambitious EU-White Paper: `Energy for the future: Renewable Sources of Energy` which was adopted in 1998. One of the key elements of the strategy for an accelerated implementation of renewable energy is to transform 100 localities within Europe into communities which are to be 100% self-sufficient with renewable energy before 2010. In line with this strategy, the Danish Government appointed the island of Samsoe towards the end of 1997 to be the first `official` Danish, renewable energy island. This is to serve as a demonstration project for other local communities, both in Denmark as well as in the rest Europe. Gothland, Madeira, Canary Islands, Cape Verde, Arki, Crete, Minorca and Orkney Islands were represented. Environmental advantages of wind, solar and wave power for distant island communities were indicated. Serious savings would be achieved by limitation of fossil fuel import and utilization of local resources. (EG)

    In this paper, we propose an optimal dispatch scheme for a cascade hydroelectric power system that maximises the head levels of each dam, and minimises the spillage effects taking into account uncertainty in the net load variations, i.e., the difference between the load and the renewable resources, and inflows to the cascade. By maximising the head levels of each dam the volume of water stored, which is a metric of system resiliency, is maximised. In this regard, the operation of the cascade ...

    1993-01-01

    Norway is about to reorganize its electricity production sector from a predominantly administered one to one which is based on market prices and principles of efficiency. The objective of this paper is to model the energy sector and to measure the size of hydro rent before and after the reorganization. We construct a regionally diversified and integrated equilibrium model of production, transmission and distribution of hydroelectricity. Particular attention is paid to the role of precipitation variability for the size and regional variation of hydro rent. We consider alternative routes for assessing the size of hydro rent in a long-run perspective. (author)

  11. Turbulence at Hydroelectric Power Plants and its Potential Effects on Fish.

    Cada, Glenn F.; Odeh, Mufeed

    2001-01-01

    The fundamental influence of fluid dynamics on aquatic organisms is receiving increasing attention among aquatic ecologists. For example, the importance of turbulence to ocean plankton has long been a subject of investigation (Peters and Redondo 1997). More recently, studies have begun to emerge that explicitly consider the effects of shear and turbulence on freshwater invertebrates (Statzner et al. 1988; Hart et al. 1996) and fishes (Pavlov et al. 1994, 1995). Hydraulic shear stress and turbulence are interdependent natural fluid phenomena that are important to fish, and consequently it is important to develop an understanding of how fish sense, react to, and perhaps utilize these phenomena under normal river flows. The appropriate reaction to turbulence may promote movement of migratory fish or prevent displacement of resident fish. It has been suggested that one of the adverse effects of flow regulation by hydroelectric projects is the reduction of normal turbulence, particularly in the headwaters of reservoirs, which can lead to disorientation and slowing of migration (Williams et al. 1996; Coutant et al. 1997; Coutant 1998). On the other hand, greatly elevated levels of shear and turbulence may be injurious to fish; injuries can range from removal of the mucous layer on the body surface to descaling to torn opercula, popped eyes, and decapitation (Neitzel et al. 2000a,b). Damaging levels of fluid stress can occur in a variety of circumstances in both natural and man-made environments. This paper discusses the effects of shear stress and turbulence on fish, with an emphasis on potentially damaging levels in man-made environments. It defines these phenomena, describes studies that have been conducted to understand their effects, and identifies gaps in our knowledge. In particular, this report reviews the available information on the levels of turbulence that can occur within hydroelectric power plants, and the associated biological effects. The final section

  12. Proliferation of hydroelectric dams in the Andean Amazon and implications for Andes-Amazon connectivity.

    2012-01-01

    Due to rising energy demands and abundant untapped potential, hydropower projects are rapidly increasing in the Neotropics. This is especially true in the wet and rugged Andean Amazon, where regional governments are prioritizing new hydroelectric dams as the centerpiece of long-term energy plans. However, the current planning for hydropower lacks adequate regional and basin-scale assessment of potential ecological impacts. This lack of strategic planning is particularly problematic given the intimate link between the Andes and Amazonian flood plain, together one of the most species rich zones on Earth. We examined the potential ecological impacts, in terms of river connectivity and forest loss, of the planned proliferation of hydroelectric dams across all Andean tributaries of the Amazon River. Considering data on the full portfolios of existing and planned dams, along with data on roads and transmission line systems, we developed a new conceptual framework to estimate the relative impacts of all planned dams. There are plans for 151 new dams greater than 2 MW over the next 20 years, more than a 300% increase. These dams would include five of the six major Andean tributaries of the Amazon. Our ecological impact analysis classified 47% of the potential new dams as high impact and just 19% as low impact. Sixty percent of the dams would cause the first major break in connectivity between protected Andean headwaters and the lowland Amazon. More than 80% would drive deforestation due to new roads, transmission lines, or inundation. We conclude with a discussion of three major policy implications of these findings. 1) There is a critical need for further strategic regional and basin scale evaluation of dams. 2) There is an urgent need for a strategic plan to maintain Andes-Amazon connectivity. 3) Reconsideration of hydropower as a low-impact energy source in the Neotropics.

  1. Framework of systematic sustainability assessment strategy (FSSAS) for hydroelectric power industry in Malaysia

    Science.gov (United States)

    Johan, Kartina; Turan, Faiz Mohd

    2017-08-01

    Hydroelectric power is an alternative power resource in Malaysia and always associated with negative impact on environmental, social and economy of the surrounding site. The dispute over environmental, societal and economic issues can be minimised if compliance to sustainability development requirement is included in the project as part of the project premises during planning phase. This paper suggests a framework targeted for decision-makers in charge of implementing the projects to produce hydropower the sustainable way in Malaysian context which can mitigate the risks in social, environment and economy. The framework is strategic in nature and based on project management methodology with objective to provide a ‘common language’ by having a project value as measureable for stakeholders to state their mutual agreement of what a sustainable hydropower project in the context of Malaysia and in line with the United Nations (UN) 17 Sustainable Development Goals (SDGs). The paper discusses how the proposed systematic sustainability assessment strategy (FSSAS) framework support the call for Malaysia to promote meaningful public participation in ensuring land and natural resource decisions and to address citizens’ interests which is the core idea of Environmental Democracy Index established in 2014. The paper argues that, even though it is at present impossible to define precision status of sustainability development with respect to the nature of the multi stakeholders and the lack of systematic assessment the proposed FSSAS framework can be a valuable tool because it tracks the project value as a quantitative deliverable to determine the status of the journey in sustainable development towards accomplishing the SDG under a consensus in hydropower industry of any scale over time.

    Full Text Available The current situation of water scarcity of of São Paulo State, manifested as imminent risk of shortages in major urban areas, has led not only to issues concerning preservation of water resources, but also problems related to energy availability, identified in a series of expeditions field carried out under the project " Electricity History of the State of Sao Paulo (1890-1960: Industrial Heritage , Landscape and Environment – Electromemory II”. The objective of this project is to study an extremely representative set of power plants and small hydroelectric power plants built during the initial period of electrification of the State of São Paulo – Brazil (1890-1960, along with its evolution within the social, historical and geographical aspects, to highlight the landscape changes resulting from the electrification process, as well as beneficiaries and impacts on landscape during the study period. In all visits, in addition to the problem of water scarcity, we verified that the power plants face generation constraints related to severe water pollution, either by diffuse or point sources. Some studies conducted in Brazil have analyzed the interference of pollution in power generation , highlighting the role of diffuse sources such as solid waste, sediments from areas with strong erosion, lubricant oils from vehicles or the development of invasive species, particularly as macrophytes, causative agents of biochemical changes that promote the formation of chemical compounds able to erode the electromechanical equipment of the plants or even prevent the flow of water intake into the same. The power plants covered by Electromemory II Project scope have these same problems, which prompted the need to establish a relationship between pollution in its various forms and the generation of electricity. To establish this bridge, the survey of publications and technical reports was necessary as well asresearches inenvironmental legislation

    In large man-made reservoirs such as those resulting from hydroelectric dam construction, bacteria transform the relatively harmless inorganic mercury naturally present in soil and the submerged plant matter into toxic methylmercury. Methylmercury then enters food webs and can accumulate in organisms at higher trophic levels. Bats feeding on insects emerging from aquatic systems can show accumulation of mercury consumed through their insect prey. In this study, we investigated whether the concentration of mercury in the fur of insectivorous bat species was significantly higher than that in the fur of frugivorous bat species, sampled near hydroelectric reservoirs in Peninsular Malaysia. Bats were sampled at Temenggor Lake and Kenyir Lake and fur samples from the most abundant genera of the two feeding guilds-insectivorous (Hipposideros and Rhinolophus) and frugivorous (Cynopterus and Megaerops) were collected for mercury analysis. We found significantly higher concentrations of total mercury in the fur of insectivorous bats. Mercury concentrations also differed significantly between insectivorous bats sampled at the two sites, with bats from Kenyir Lake, the younger reservoir, showing higher mercury concentrations, and between the insectivorous genera, with Hipposideros bats showing higher mercury concentrations. Ten bats (H. cf. larvatus) sampled at Kenyir Lake had mercury concentrations approaching or exceeding 10 mg/kg, which is the threshold at which detrimental effects occur in humans, bats and mice.

    2008-01-01

    This article described the environmental impacts caused by the exploitation of one or several dams in tropical coastal basins. In particular, it proposed a methodological approach for analyzing the vulnerability of ecosystems to modifications caused by the exploitation of the Garafiri hydroelectric dam in Guinea. With an installed power capacity of 75 MW, this dam has been operational since 1999 and has supplied electricity to coastal and mid Guinea since 2000. Since then, the ecosystem of the Konkoure River has undergone important changes. This study focused primarily on impacts during the dry season. Data was collected at different hydroelectric stations along the Konkoure Basin to estimate changes in water flow in the estuary. The study showed several changes, including noticeable impacts on the soil salt content. In addition, changes in vegetation were attributed to changes in soil content. The study revealed that rice production has increased 65 per cent since 2000, while salt exploitation has been completely discontinued. It was concluded that the hydraulic management of the dam can have a significant impact on the region's ecosystem which can in turn influence ecological and social economic functions. It was concluded that the vulnerability of the ecosystem can be worsened in the context of climate change. 25 refs., 9 figs

    2016-10-01

    Full Text Available Hydroelectric systems are well-known for large scale power generation. However, there are virtually no studies on energy harvesting with these systems to produce tens or hundreds of milliwatts. The goal of this work was to study which design parameters from large-scale systems can be applied to small-scale systems. Two types of hydro turbines were evaluated. The first one was a Pelton turbine which is suitable for high heads and low flow rates. The second one was a propeller turbine used for low heads and high flow rates. Several turbine geometries and nozzle diameters were tested for the Pelton system. For the propeller, a three-bladed turbine was tested for different heads and draft tubes. The mechanical power provided by these turbines was measured to evaluate the range of efficiencies of these systems. A small three-phase generator was developed for coupling with the turbines in order to evaluate the generated electric power. Selected turbines were used to test battery charging with hydroelectric systems and a comparison between several efficiencies of the systems was made.

  6. Effectiveness of water release as mitigation for hydroelectric impacts to fish

    1995-01-01

    Utility companies release water to mitigate the effects of hydroelectric projects on fish habitats. Utility companies, government agencies, and research communities in Canada, the US, Europe, New Zealand, and Australia were surveyed as part of a Canadian Electrical Association study to evaluate the effectiveness of water release as a mitigation. Respondents identified only 28 projects in which water was released specifically to protect fish habitats. Fewer than half of these projects (12) were judged as being effective. Six case histories with preimpact assessment and postimpact monitoring were reviewed. In four cases fish habitat or fish populations or both were maintained; in two cases they were not. The effectiveness of water release differed among rivers and fish species, and was greatest when designed to meet the habitat requirements of each life-history stage. A review of the literature did not support the theory that a particular fraction of the mean annual flow provides the bet fish habitat. Although smaller changes in the flow regime had smaller effects, increasing minimum flows above those historically observed did not necessarily increase fish production

    A description is given of the hydroelectric construction project as well as the environment surrounding it, the outcome of consultations with interest parties in the public, the overall environmental impacts and cumulative impacts with associated problems that may occur in carrying out the project, attempts at project and environmental mitigation, measuring the importance of the cumulative and environmental effects, conditions for project acceptance, and the overall acceptance of the project or its rejection. The older hydroelectric project was constructed in the post-1910 period and being out of date is experiencing operational problems. There are four problem areas that are important including a need for major repairs to the turbine-generators, lack of flexibility and low electrical capacity that affect the working of the sending-end substation, a state of deterioration affecting operation of the spillways concrete structure, and a bottleneck problem on the Saint-Maurice river caused by the low flow design of the Grand-Mere power station in comparison with that of the Saint-Maurice station. Considering economical, social and environmental factors, of the three options of abandoning the site, upgrading the existing site or constructing a new one, the third option is the preferred one, a conclusion based on considering the out of date state of Grand-Mere facilities and the bottleneck flow condition created on the Saint-Maurice river by the older station. Given the proposed efforts at mitigation, and the follow-up operations stated by the third option advocate, the Department of Fisheries and Oceans is of the opinion that the proposed plans will not affect the environment in an adverse manner. 7 refs

    Full Text Available This article proposes a process framework for developing and managing visitor attractions (VA in small island developing states with Trinidad and Tobago, a two-island state in the Caribbean, as the case study. An extensive literature review was conducted, supported by field observations, individual depth interviews, and small and large focus group meetings. The process framework identified four sets of processes: national policy formulation and legislation; inventory, classification, evaluation, and ranking of VA; general operations management involving project management activities; and site specific activities of development, operations, and maintenance. The value of the framework lies in the fact that no similar framework applicable to small islands was covered in the literature and validation was obtained from a panel of experts and a cross section of tourism stakeholders in Tobago.
