  • Modernization of Century-Old Hydro Facility Yields Rich History

    When the Boulder Canyon Hydroelectric Facility was built in the steep, forested mountains between Boulder and Nederland, Colo., in 1910, it was the highest head hydroelectric facility in the western U.S.

  • TOP PLANT: Three Gorges Dam, Yangtze River, Hubei Province, China

    After nine years of construction, installation, and testing, the Three Gorges Dam is now complete. On May 23, 2012, the last main generator finished its final test, increasing the facility’s capacity to 22.5 GW and making it the world’s largest capacity hydroelectric power plant.

  • Renewable Energy Development Thrives During China’s 12th Five-Year Plan

    China’s 12th Five-Year Plan calls for expanding the use of renewable energy in all forms throughout the country. From solar and wind to biomass gas and briquettes, China has a true “all of the above” renewable energy policy.

  • Hawaii’s Largest Wind Project Online as State Struggles to Integrate Renewables

    On Monday, as First Wind announced its 69-MW Kawailoa Wind Project had gone into commercial operations on Oahu, other news underscored the difficulty the island state faces in trying to substitute renewables for expensive, imported fossil fuels.

  • Trend Shows Growth of Renewables on Contaminated Lands

    Renewable energy projects installed on potentially contaminated lands, landfills, and mine sites have increased by 40% since 2008, a new list released last week by the Environmental Protection Agency (EPA) shows. Solar photovoltaic (PV) systems make up the bulk of about 184.7 MW installed at 60 sites in 25 U.S. states.

  • Three Gorges Dam Completed Amid Technical Victories, Controversy

    China in early July installed the 32nd and final turbine of its mammoth Three Gorges Dam, virtually completing the controversial 1994-initiated hydropower project on the middle reaches of the Yangtze River.

  • Chile’s Power Challenge: Reliable Energy Supplies

    Droughts, unreliable gas imports, and protests against proposed projects have hampered the Chilean power sector and its largest economic driver, the copper-mining industry. Recent policies designed to foster more reliable supplies are a move in the right direction, but remaining obstacles are formidable.

  • Major Developments for Solid Oxide Fuel Cells

    Solid oxide fuel cells (SOFCs), which oxidize a fuel to produce electricity, have received much attention of late for the technology’s myriad benefits, including high efficiency, long-term stability, fuel flexibility, and low carbon emissions—all at a relatively low cost.

  • Tubular Turbine Hydropower Plant Comes Online

    Albania this June inaugurated its first major hydropower project since the early 1980s, bringing online Ashta I, the first of two run-of-river plants with a combined capacity of 53 MW. At the inauguration ceremony, Albania’s Prime Minister Sali Berisha called the plant “a novelty” because it is the largest in the world to use advanced tubular turbines technology.

  • FERC Rule 1000: What Does It Mean?

    The Federal Energy Regulatory Commission (FERC) has the responsibility for ensuring just and reasonable rates and preventing undue discrimination by public utility transmission providers. Last year FERC defined a new framework for public utilities and regional transmission organizations planning new transmission networks. The framework is provided in Order No. 1000—Transmission Planning and Allocation by Transmission Owning and Operating Public Utilities. The Final Rule was issued on July 21, 2011, and reaffirmed by Order No. 1000-A on May 17, 2012.
