The Nuclear Regulatory Commission (NRC) on Friday extended a construction permit for the Tennessee Valley Authority’s (TVA’s) unfinished Unit 1 reactor at the Bellefonte site near Scottsboro, Ala. The agency last week also listed actions Dominion must take before restarting operation of the quake-hit twin-reactor North Anna nuclear power plant near Louisa, Va.

Stirling Energy Systems, the Scottsdale, Ariz., maker of a reflective dish that concentrates sunlight onto a Stirling engine, has reportedly filed for Chapter 7 bankruptcy—making it the fourth solar company to fall this year amid the plummeting price of solar photovoltaic (PV) panels.

Hours before the Department of Energy’s (DOE’s) controversial advanced energy loan guarantee program (funded under the 2009 American Recovery and Reinvestment Act) expired on Friday, the agency finalized seven loan guarantees totaling more than $5.9 billion. Projects include solar power facilities in California, Nevada, and Arizona, and a bioenergy project in Kansas.

Sixty projects in 25 states were awarded a total of $156 million on Thursday under the Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) agency. They focus on accelerating innovations in clean technology while increasing America’s competitiveness in rare earth alternatives and breakthroughs in biofuels, thermal storage, grid controls, and solar power electronics.

Over the past 18 months, four solar energy equipment companies have closed their doors. Each one blamed poor market conditions for its economic woes, even though each had fundamental weaknesses that went unaddressed. It now appears that the Department of Energy (DOE) did insufficient due diligence before backstopping one of those four companies, Solyndra, with a $535 million loan guarantee.

The German government in July finalized a package of bills that will phase out nuclear’s 23% contribution to the country’s power supply by 2022 and increase renewable generation from the current 17% to 35%. In August, the Federal Network Agency ( Bundesnetzagentur) said it wouldn’t rely on power from seven of the nation’s oldest reactors […]

In China this August, as Ling Ao Unit 4—the second unit of the Ling Ao Phase II nuclear plant—started commercial operation, Westinghouse and its consortium partners marked the milestone of receiving the reactor vessel for the Sanmen nuclear power plant—the world’s first AP1000—in China’s Zhejiang province. The start-up of Ling Ao Unit 4 in Guangdong […]

As utilities in California are scrambling to meet the state’s 33% renewable mandate by 2020, a 49.6-MW peaking plant in Modesto, Calif., built by Finnish firm Wärtsilä for the Modesto Irrigation District, has been commissioned to provide flexible, fast-start peaking generation to balance the state’s increase in intermittent renewable generation (Figure 4). 4. Flexible peaking. […]

Kuwait put online the first 1,400 MW of its massive 2,000-MW combined cycle gas turbine Sabiya facility in June to mitigate looming power shortages it faces each summer. The plant—Kuwait’s largest power plant and one of the largest in the Gulf region—is now operating six GE 9FA gas turbines; the remaining 600 MW are expected […]

A new analysis of 85 hydroelectric reservoirs distributed around the world suggests that these systems emit about 48 million metric tons of carbon annually. That figure is much lower than earlier estimates of 64 million metric tons that were based on studies relying on more limited data and which cautioned that reservoirs of all types […]
