  • 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 ...

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

    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 ...

  • Evaluation of melioration area damage on the river Danube caused by the hydroelectric power plant ‘Djerdap 1’ backwater

    Construction of the hydroelectric power plant (HPP) ‘Djerdap 1’ formed a backwater effect on the Danube and its tributaries, which had an inevitable influence on groundwater level, causing it to rise and thus creating additional threats to all melioration areas on more than 300 km of the Danube riversides, as well as on the riversides of its tributaries: the Sava (100 km) and the ...

  • 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 ...

  • Continuous Quality Surveillance Scheme to minimize the Cost Of Poor Quality in the construction of hydroelectric powerplants - IDRA 2012

    During the construction of hydroelectric plants, poor quality can have a hugely negative impact on construction time, on plant performance and on safety. We propose a method of keeping under control the manufacturing of the most critical components, such as pressure parts, rotors and valves, with a view to minimizing the Cost of Poor Quality (COPQ). This method is known as the Continuous Quality ...

  • Oil-Water Separator with New Coalescing Media Handles High Load Stormwater at HydroElectric Powerplant to Yield Zero Oil Discharge

    Background Removal of oil from water before the water is discharged into a river or other body of water is an important environmental goal. In order to accomplish this, a major hydropower producer in the southern United States contracted with HydroQuip, Inc.* for the supply of a state of the art oil/water separator. The power plant had several goals, but the most important was that in ...

  • Power Plant Asset Transactions Managing Environmental Issues

    Deregulation of the electricity industry has spawned unprecedented asset transfer activity among electric generating companies. Many companies are focusing on generation, while a large number of former generating companies are shifting their focus to concentrate on power distribution and communication initiatives. The result is a significant turnover of power plants to new owners as generating ...

  • 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 ...

  • 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 ...

  • Power plants use oil skimmers to prevent contamination from spills

    Most hydroelectric plants designed in the 1960s were built with a station drainage sump that collects all drainage from the plant. As designed, float switches activate sump pumps that discharge liquids directly into the tailrace. The system cannot distinguish between types of liquids, so in the event of an oil leak, oil in the sump could be released into the tailrace. Modern ...

  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • Columbus, Georgia`s High-Efficiency, Low Cost, Digester-Gas-Fired Power Plant

    ABSTRACTGrowing concern over the cost of power and long-term availability of limited fossil fuel resources for the production of electricity have caused electrical utilities and governments to promote “green” or renewable power. Solar, wind, geothermal, biomass, biogas, and low-impact hydroelectricity are current acceptable green-power sources. Digester gas is a renewable, green energy resource ...

  • 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 ...

  • Railroad track ballast crushing and screening plant

    Track ballast forms the track bed upon which railway sleepers (UK) or railroad ties (US) are laid. It is packed between, below, and around the ties. It is typically made of crushed stone, although ballast has sometimes consisted of other, less suitable materials. The crushed stone comes from the stone crushing and screening plant, and DSMAC supply high efficiency railroad track ballast crushing ...
