  • 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 ...

  • Lake Dorothy Hydroelectric Dam Completion Benefits Alaska Residents

    The Lake Dorothy Hydroelectric Project, located near Juneau Alaska, was begun in 2006 and completed in 2010.  Karl Vander, of North Pacific Erectors, was the Project Manager.  North Pacific Erectors, a General Contractor for ...

  • Health and environmental impacts of the hydroelectric fuel cycle

    The impacts on health and the environment and the associated damage costs caused by the hydroelectric fuel cycle are assessed in this paper. To this purpose, a large hydroelectric project along the Nestos river in northern Greece has been selected as an example. A large number of impacts have been identified. Occupational accidents, impacts on agriculture and forests, noise produced during the ...

  • The blue water footprint of electricity from hydropower

    Hydropower accounts for about 16% of the world’s electricity supply. It has been debated whether hydroelectric generation is merely an in-stream water user or whether it also consumes water. In this paper we provide scientific support for the argument that hydroelectric generation is in most cases a significant water consumer. The study assesses the blue water footprint of hydroelectricity ...

  • 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 ...

  • Small hydro projects – renewable or ruinous?

    With thousands of rivers and streams running through British Columbia, small hydro energy projects seem like a significant source of renewable energy. Although such projects have low environmental impacts compared to major hydro-electric dams, they face a significant level of opposition from the public. ...

  • Data Highlight: Hydropower Continues Steady Growth

    World hydroelectric power generation has risen steadily by an average 3 percent annually since 1965. In 2011, at 3,500 billion kilowatt-hours, hydroelectricity accounted for roughly 16 percent of global electricity generation, almost all produced by the world’s 45,000-plus large dams. Graph ...

  • GE Leakwise Application Notes: Oil Detection in Hydro-Electric Power Plants

    Leakwise* Oil Detection in Water Collection Sump Under Turbines Water carries oil leakage from turbine bearings and other leaking sources into a large sump, which is built under the turbines. In most plants, pumps installed at the bottom of the sump discharge the water directly to the river.  A Leakwise lD-221 Floating Oil Detector is installed in a perforated 6” stilling well. The ...

  • Brazil Power Report Q1 2013

    While hydroelectric sources of power account for, and will continue to account for, the majority of Brazil’s electricity consumption requirements, over the course of our forecast period gas-fired power stations will gain importance, as will renewables and nuclear sources of power, once Angra 3 begins operations in 2016. Brazil’s ambitious Belo Monte hydroelectric dam project ...


  • 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 ...

  • 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 ...

  • Canada’s Other Energy Boom – Energy infrastructure is on the move.

    When it comes to energy infrastructure, Canada is on the move. Of course, that may seem like nothing new, given Canada’s lengthy energy history, particularly in the oil and gas industries. In this latest chapter, however, electricity is playing a major role. A confluence of factors have helped spur the need for more generation, which in turn is driving still another form of energy ...

  • Solar thermal power coming to a boil

    After emerging in 2006 from 15 years of hibernation, the solar thermal power industry experienced a surge in 2007, with 100 megawatts of new capacity coming online worldwide. During the 1990s, cheap fossil fuels, combined with a loss of state and federal incentives, put a damper on solar thermal power development. However, recent increases in energy prices, escalating concerns about global ...

  • Generating Ecological Gains from Hydro-Electric Power - Case Study

    NCC has worked with Eskom to mitigate the environmental impacts of the Ingula Pumped Storage Scheme on a sensitive wetland site in the Little Drakensberg/Escarpment, including creating and managing a new conservation area. South Africa’s energy demand is growing at rates of around 5% a year, placing enormous pressure on Eskom not only to create new generating capacity, but also to manage ...
