  • TOP PLANT: Stillwater Solar-Geothermal Hybrid Plant, Churchill County, Nevada

    The Stillwater hybrid facility is the world’s first renewable energy project that pairs geothermal power’s baseload generation capacity with solar power’s peak capacity. Inaugurated in May, the 26-MW solar plant is integrated with the adjacent 33-MW geothermal plant, which began operations in 2009, and provides energy to run the geothermal plant’s auxiliary loads.

  • Too Dumb to Meter, Part 6

    As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the eighth, ninth, and 10th chapters, “Flightless Birds and Flying Elephants,” “The Devil Flies Nukes,” and “Flatulence in Space,” the concluding chapters of the “Up in the Air: Flights of Radioactive Fancy” section.

  • 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.

  • Under Siege

    As I write this column on Election Day 2012, the polls are still open and both presidential candidates are predicting victory. The next dozen hours or so will prove only one candidate correct. Regardless of the outcome, wind power remains a loser.

  • TOP PLANT: Walney Offshore Windfarms, Irish Sea, UK

    Officially commissioned in February 2012, the two Walney Offshore Windfarms—Walney 1 and Walney 2—together have 102 wind turbines with a total capacity of 367.2 MW. With their combined capacity, the windfarms qualify as one of the world’s largest offshore wind energy facilities and provide clean electricity to approximately 320,000 UK households.

  • Distributed Solar Challenges Utilities, Markets, and Regulation

    Electricity produced from solar energy is being added to the grid—before and after the meter—in greater amounts each year. The uniqueness of this resource is pushing utilities, developers, users, and regulators to develop new and innovative interconnection rules and to rewrite some old rules that balance the costs and rewards among stakeholders.

  • Vanadium Flow Battery Juices Onion Plant

    An emerging flow battery technology got a major boost earlier this year when Gills Onions, one of the largest fresh-cut onion processing plants in the world—began operating a 3.6-MWh vanadium redox battery (VRB) energy storage system (ESS).

  • 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.

  • Largest Wastewater Treatment Fuel Cell Plant Goes Online

    In October, Canadian biogas power producer Anaergia opened a 2.8-MW fuel cell system powered by cleaned and conditioned wastewater biosolids at a municipal water treatment facility in Ontario, Calif.
