  • Long Tan Hydroelectric Dam

    Black & Veatch is the design and construction consultant for the world's largest roller-compacted concrete dam, which will be the world's fourth largest hydropower station and protect 12 million people from flooding. China must create urban infrastructure for the equivalent of the city of Houston, Texas, every month for the next 30 years to accommodate the relocation of 280 million rural ...

  • 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 institutional co-evolution in diffusion of hydroelectric power technology

    The introduction and significant momentum on diffusion of wind power as a new technology for energy production involve a push for changing the institutional framework in the energy sector. The introduction of hydro (electric) power technology and the following institutional change process may be compared to the introduction of wind power 90 years later. In this paper, the main focus is on the ...

  • 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 ...

  • Idaho Water District’s new Hydroelectric project - case study

    This Irrigation District north of Twin Falls installed a new run of the river hydroelectric facility. In order to protect their new turbines, they installed this Traveling Water Screening System. The majority of debris consists of weeds, tumbleweeds, aquatic plants and urban debris. The 5 screens at this location drop debris on a 60’ long conveyor. The conveyor carries the debris to an ...

  • 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 ...

  • No Place Is Too Far

    The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...

  • 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 ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...
