  • 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 ...

  • Hydroelectric Power Stations and Fish Migration

    Hydroelectric power stations in rivers produce potential injury to downstream migrating fish as they pass through the turbines. Highest mortality rates are found for eel and ranges between 15 and 38%. The impact of fish passage through a series of hydroelectric power stations in one river can be very high. This might be the case for river systems like the river Rhine or Meuse where many ...

  • 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 ...

  • 1997 IFAI award devil Canyon hydroelectric power plant, San Bernardino, California - Case Study

    Constant demands for water and electricity in heavily populated areas in California prompted the Devil Canyon Power Plant project. Constructed from 1969 to 1974, the power plant is located at the San Bernardino Mountains near the mouth of Devil Canyon. With two pipelines carrying water from Silverwood Lake, an elevation drop of almost 1500 ft (460 m) between the lake, and four Pelton wheel ...

  • A novel technique proposed for automatic control of small hydro power plants

    A new scheme is proposed for the speed control of hydro turbines. Power can be controlled by controlling the rotary motion of the spear valve or linear motion of the sluice gate. In this paper, necessity for speed control, various function of governors, types, speed regulation of micro-hydroelectric power plants, functional block diagram of power generation and control system general models for ...

  • Iberdrola to build nine wind farms in Brazil

    Spain’s Iberdrola Renovables and its Brazilian partner, energy company Neoenergia, have received a contract from Brazil’s Agencia Nacional de Energia Electrica (Aneel) to deliver the electric output of nine wind farms—a deal characterized as a major step in allowing the Iberdrola-Neoenergia consortium to move ahead with construction of the facilities. The nine wind ...

  • Intro to Hydropower Part:2 Measuring head & flow

    Measuring the stream course—Anna and Joe work downstream, shooting vertical drop (head) with a sight level, and getting a rough measurement of the pipe run at the same time. Small-scale hydro is the only renewable energy source that works for you 24 hours a day, 7 days a week. In the first article in this series (HP103), I explained the basics of hydroelectric system theory, and ...

  • 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 ...

  • 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 ...
