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 […]

Integrating California Independent System Operator’s (CAISO’s) and PacifiCorp’s networks—the two largest high-voltage transmission grids in the West—could yield billions of dollars in shared cost reductions within the first 20 years alone through efficiencies, a new study says.  The report commissioned by PacifiCorp stems from a memorandum of understanding signed by the independent system operator (ISO) […]

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 […]

Within the space of less than a week, four deals have been announced that will result in ownership changes at five power plants in the U.S. Northeast. Calpine Buys Another Gas Plant Calpine Corp. announced on Oct. 13 that it has agreed to acquire the Granite Ridge Energy Center, a 745-MW combined cycle gas-fired power […]

A federal court last week granted a motion barring the U.S. Army Corps of Engineers and Environmental Protection Agency (EPA) from enforcing the Clean Water Rule, which critics say is “exceptionally expansive.” A three-judge panel at the U.S. Court of Appeals for the Sixth Circuit on Oct. 9 granted the stay sought by 31 states […]

Entergy Corp. will permanently close its 680-MW Pilgrim nuclear power plant in Plymouth, Mass., by June 2019, owing to poor market conditions, reduced revenues, and increased operational costs, the company said today.  The New Orleans–based company said it has notified grid operator ISO-New England (ISO-NE) that the reactor that began operations in 1972 would not […]

Alberta-based Carbon Engineering is inaugurating a pilot project today in Squamish, British Columbia, that will capture carbon dioxide (CO2) directly from the atmosphere. The company, funded by private investors, including Microsoft founder Bill Gates and oil sands financier Murray Edwards, has developed technology based on research conducted by Harvard University–based Professor David Keith’s research groups […]

India and 73 other countries submitted their carbon emission reduction targets for 2025 and 2030—or Intended Nationally Determined Contributions (INDCs)—ahead of the deadline last week, with just two months remaining until talks to confront climate change are due to begin in Paris.  The United Nations (UN) has so far received 120 separate pledges covering 147 […]

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 […]

Xcel Energy said on Oct. 2 that the company would accelerate its transition from coal power to cleaner energy sources by retiring two units at its Sherburne County Generating Plant (Sherco) in Becker, Minn. The decision is part of the company’s strategy to cut carbon emissions 60% by 2030. The Sherco plant is Xcel’s largest […]
