  • Black river falls hydro - Case study

    CHC provided a complete water-to-wire equipment package to the City of Black River Falls, Wisconsin, for the upgrade of its Black River Falls Hydroelectric Dam, located on the east bank of the Black River in Jackson County, Wisconsin. This historic dam rebuilding project was completed in June 2012, and involved the installation of an additional low-flow generating unit. The water-to-wire ...

  • River Dommel (NL) - Case Study

    In the spring of 2016 the construction of a new hydropower plant in the Dommel river near Sint-Michielsgestel started. The existing dam in the river is equipped with a Landustrie hydropower screw and will generate renewable energy for approximately 200 households. The Dommelstroom project is the first cooperative hydropower power plant in the Netherlands, initiated by Bram and Jan Taks, father ...

  • A conceptual framework for real time estimation of WFP for small hydroelectric power plant

    It is believed that the power sector, particularly hydroelectric power, contributes to a very high consumption of fresh water in terms of evaporation from storage reservoirs. Robust methods of water footprint (WFP) assessment will eventually help in the pricing of water and energy. Conventionally, WFP for hydropower plants is estimated by dividing the gross/net evaporation losses by power ...

  • Extended multi-objective firefly algorithm for hydropower energy generation

    Classical methods have severe limitations (such as being trapped in local optima, and the curse of dimensionality) to solve optimization problems. Evolutionary or meta-heuristic algorithms are currently favored as the tools of choice for tackling such complex non-linear reservoir operations. This paper evaluates the performance of an extended multi-objective developed firefly algorithm ...

  • Microhydro-Electric Systems Simplified

    If you have a suitable site, harnessing the energy in a stream or creek can be the most cost-effective way to make renewable electricity. Compared to the sun and wind’s variability, a stream’s flow is relatively consistent, making microhydro-electric system output the most predictable of all the renewable energy (RE) electrical systems. Hydro ...

  • How to make hydropower more environmentally friendly

    Hydropower provides 85 percent of the world’s renewable electricity, but comes with a hefty environmental price tag. Here’s what some are doing to fix that. Humanity got its first large-scale electricity thanks to hydropower. On Aug. 26, 1895, water flowing over Niagara Falls was diverted to spin two generators, producing electricity to manufacture aluminum and carborundum. Since ...

  • The Global Arc Towards Renewable Energy

    Introduction Given the United States’ recent election results, America’s future on climate and energy policy is uncertain, but global progress on mitigating climate change will continue with or without us. We have reason to be optimistic because countries around the world have demonstrated their commitments to taking action on global warming. Already, 114 countries have ...

  • Optimal control of reservoir release temperature through selective withdrawal intake at hydropower dam

    This study is motivated by the need to understand the temperature dynamics and warm-water temperature withdrawal. This study also recognizes the need for an environmental assessment of the proposed temperature control schemes at New Fengman Dam. An unsteady three-dimensional (3D) non-hydrostatic model is used in the present study to predict the hydrodynamics and thermal dynamics in the forebay ...

  • Powering Renewable Programs: The Utility Perspective

    When considering how to build out a renewable energy portfolio, there are a lot of factors and many points of view to consider. For purposes of this narrative, we will take the point of view of the electric utility itself. Your electricity providers are quite familiar with the concept of a “smart grid.” According to the Department of Energy (DOE), a smart grid “generally refers ...

  • Monitoring Hydroelectric Dam Sumps - Case study

    The Situation Hydroelectric dams produce electric power by harnessing the force of the water flowing through the dam. There are numerous sources for oil spillage: The hydroelectric turbines are lubricated by lubrication oils. The very large water control valves are normally hydraulic powered and are lubricated with various greases and oils. Vehicles ...

  • An assessment of reservoir filling policies for the Grand Ethiopian Renaissance Dam

    Africa's largest hydropower facility is currently under construction on the main stem of the Blue Nile River in Ethiopia. The Grand Ethiopian Renaissance Dam (GERD) is poised to facilitate regional development with a 63 billion cubic meter reservoir and 6,000 MW of power generating capacity. To date, however, no reservoir filling rate policy has been established. This policy will have ...

  • Saving Renewable Energy for a Rainy Day

    Despite advances in renewable energy technologies, one of the largest hurdles in their widespread adoption has been their intermittent reliability. Energy is only useful if it is available as the grid demands it, which is why concerns about carbon emissions are overridden in favor of the more dependable oil, coal and gas for baseload power. In order for renewable sources such as wind and solar ...

  • Energy recovery in the water industry using micro-hydropower: an opportunity to improve sustainability

    The water industry as a whole consumes a considerable amount of energy in the treatment and distribution of water and wastewater. Like all sectors of society today, the industry is focusing efforts on reducing its CO2 emissions and improving the sustainability of its systems and practices. One way of achieving this is through the use of micro-hydropower (MHP) installations in water ...

  • SHP stations and integrated rural development: a multivariate statistical approach

    The multi-functional role of the rural space is gradually being enhanced in recent decades, as agriculture seems to be losing its leading position. The diversification of local economies through the exploitation of natural resources is being highlighted as a fundamental driving force for development. Renewable Energy Resources (RES) and, more specifically, the establishment of Small Hydropower ...

  • Large-scale hydropower system optimization using dynamic programming and object-oriented programming: the case of the Northeast China Power Grid

    This paper examines long-term optimal operation using dynamic programming for a large hydropower system of 10 reservoirs in Northeast China. Besides considering flow and hydraulic head, the optimization explicitly includes time-varying electricity market prices to maximize benefit. Two techniques are used to reduce the ‘curse of dimensionality’ of dynamic programming with many ...

  • Risk sharing in hydropower development: case study of the Chukha Hydel Project in Bhutan

    The Himalayan rivers have an enormous hydropower potential that is still not exploited fully for the benefit of the region. Bhutan and Nepal together have an economically feasible potential of 60,000 MW of hydroelectric power generation capacity but are too weak financially to bear the risks associated with the development of their hydro resources alone. India is the only potential market for ...
