The one-day-in-10-years criterion might have lost its usefulness in today’s energy markets. The criterion is highly conservative when used in calculating reserve margins for reliability. Can the...

will be purchased by Kyushu Electric Power Company. First Solar holds 100 percent equity in the project. Obayashi Corporation and Yaskawa Electric Corporation constructed the project.
DTE Energy Services (DTEES) finished work on its construction project to convert a shuttered coal-fired power plant at the Port of Stockton, California, to operate on biomass fuel. The plant, known as Stockton Biomass, began commercial operations on Feb. 21. It is selling its renewable power to PG&E. The plant will use about 320,000 tons of woody biomass fuel annually to generate about 45 MW of power. The fuel primarily is derived from urban wood waste, tree trimmings and agricultural processes. The plant began operation in 1989 as a coal-fired power plant and ceased operation in April 2009. DTEES purchased it in June 2010 with plans to convert the plant to biomass.
Duke Energy Renewables acquired two 20-MW California solar projects from renewable energy developer Infigen Energy . The Pumpjack and Wildwood Solar Power Projects, located in Kern County near Bakersfield, represent Duke Energy Renewables' third and fourth utility-scale solar power projects in the state. The solar energy generated from the two projects will be sold through 20-year PPA with Southern California Edison .
GE unveiled its 2.75-120 wind turbine, part of GE's "Brilliant" wind platform, which analyzes thousands of data points every second to help integrate operations with neighboring turbines, both to boost power output and to provide short-term predictable power through integrated energy storage. The 2.75-120 provides 5 percent more annual energy production than GE's 2.5-120 model and is available with various tower technologies, ranging between 85-139 meters, with energy storage as optional. The new turbine is available on a steel, hybrid or space frame tower. The range of tower height spans 85-139 meters tall.
ABB won orders worth $45 million from Svenska kraftnät, the Swedish National Grid operator, to supply three 400-kV substation to strengthen the Swedish power grid. The substations are scheduled to be commissioned in 2015. ABB's project scope includes the design and supply of engineered packages for the high-voltage air-insulated switchgear (AIS) substations. Key products and systems to be supplied cover a range of high-voltage equipment, including a combined disconnector and circuit breaker (DCB).The DCB will integrate the disconnecting function into the circuit breaker and eliminates the need for two separate free-standing disconnectors. The substations will also be equipped with IEC 61850 based open control and protection systems and equipment.
Babcock & Wilcox Nuclear Energy (B&W NE) was awarded a contract from American Electric Power (AEP) to provide steam generator services for the Donald C. Cook (D.C. Cook) Nuclear Plant just north of Bridgman, Mich. The D.C. Cook Plant contains two units, one of which is outfitted with Babcock & Wilcox replacement recirculating steam generators. As part of this contract, B&W NE will execute a comprehensive inspection and cleaning campaign, which includes eddy current testing, visual inspections, and water lancing. The inspections and cleaning activities are conducted periodically to monitor and maintain the condition of the steam generators.
