The 400-MW coal-fired Sunbury Power Plant in Snyder County, Penn., retired in 2014, will be replaced with a three-unit, 1.1-GW combined cycle plant, private equity firm Panda Power Funds announced on Oct. 28. The four-unit Sunbury facility, which began operations in 1949, was shuttered last year after 65 years of operation. Originally built for Pennsylvania […]

Battery storage has emerged from the fringes of the power sector to challenge both industry conventions and traditional generation. Where it goes from here, however—the future of battery storage technology—is a matter of some debate. Both storage firms and energy storage experts at the Energy Storage North America (ESNA) conference in San Diego Oct. 13-15 […]

Energy storage needs better energy storage policy. Speaking at the Energy Storage North America (ESNA) conference in San Diego on Oct. 12, Garrett Fitzgerald, senior associate with the Rocky Mountain Institute (RMI), was frank about the challenge facing energy storage technologies: They’re starting to get well ahead of the regulatory regimes that are needed to […]

Coal has been the dominant source of electricity in the U.S. power mix for more than a century, but that may be coming to an end sooner than expected. For only the second time ever, but also the second time this year, gas generated more electricity in the U.S. than coal. According to statistics from […]

Battery energy storage has exploded in deployment over the past several years, but the majority of it by capacity, especially in North America, is deployed at grid scale. That may be a problem, because a new study from the Rocky Mountain Institute (RMI) suggests the greatest value to the system lies with behind-the-meter batteries—distributing battery […]

The Environmental Protection Agency (EPA) on Oct. 1 released the final version of new National Ambient Air Quality Standards (NAAQS) for ozone, cutting the current limit of 75 ppb to 70 ppb. The move sets the stage for a battle with Congress, the states, and a range of industries that have warned the new ozone […]

After years of stressing the conventional virtues of geothermal power production—reliable, baseload renewable energy from geological sources—the geothermal industry and the U.S. government are looking at ways technology can change the hot rocks game and give a boost to an often-overlooked resource. Legendary venture capitalist Vinod Khosla, who made a pile of money in information […]

Duke Energy announced on Sept. 29 that it had agreed to pay a $7 million fine to resolve all groundwater issues with the North Carolina Department of Environmental Quality (NCDEQ) relating to its 14 facilities in the state.
