Two nuclear plants owned by Exelon Corp. in Illinois and Pennsylvania failed to clear PJM Interconnection’s latest annual capacity auction, putting one of those financially crippled units at risk of early retirement. Meanwhile, procurements for solar, wind, and demand response fell dramatically compared to last year, and drastic price declines could roil the market for […]

Grid-connected batteries have long been touted as a tantalizing prospect that could help balance electricity supply and demand as the amount of installed variable renewable generation ramps up. New

The U.S. Energy Information Administration (EIA) expects natural gas–fueled electricity generation will exceed all other fuel sources once again this summer, marking the third year in a row that gas has been the leader. However, the EIA anticipates electricity generation from both gas and coal will be less this summer than in 2016. The reason […]

Global new renewable power capacity grew in 2016 even as global new investment in renewables dropped, according to a report commissioned by the United Nations Environment Program out April 6. The Global Trends in Renewable Energy Investment 2017 report found that global investment in renewables—excluding large hydro—fell in 2016 by 23% to $241.6 billion. That […]

Russia Marks Milestone with Commercial Operation of Third-Generation Reactor. After nearly a decade of construction, the first advanced third-generation VVER-1200 nuclear reactor began commercial operation on

Technology advancements and new regulatory requirements could reshape how power plant owners operate and maintain large power transformers. Experts outline emerging strategies and call attention to overlooked

Siemens has installed the prototype of its towering 8-MW offshore direct-drive wind turbine at a national test center in Østerild, Denmark, marking the company’s foray into the global race to develop mega–wind turbines. The new offshore turbine was installed on a steel tower at a hub height of 120 meters (m) in late January (Figure […]

The boom in renewable energy, spurred by dramatically falling costs, has led some experts and political figures to begin talking seriously about what was once science fiction: A world powered entirely by renewable generation. But is it truly feasible or economic? One series of studies suggests it is—with some important caveats. In the first half […]

A large swath of the central U.S. set a North American wind penetration record of 52.1% early in the morning on February 12, the Southwest Power Pool (SPP) reported. The regional transmission organization (RTO), whose footprint spans 550,000 square miles from the Canadian border in Montana and North Dakota to parts of New Mexico, Texas, […]
