New York, Connecticut, Massachusetts, New Hampshire, Rhode Island, and Vermont on October 7 filed a lawsuit in the U.S. District Court for the […]

Mississippi Power’s integrated gasification combined cycle (IGCC) plant in Kemper County, Miss., on October 12 has begun generating its first power using a combination of syngas (produced from locally mined lignite) and natural gas. The milestone is a major one, said Thomas Fanning, CEO of Mississippi Power’s parent company Southern Co. “After decades of research […]

Academics at the University of Sheffield—a public research university in the UK—have begun two new carbon capture and storage (CCS) projects, searching for cheaper methods of capturing carbon dioxide (CO2) from fossil-fueled power plants. The work is being funded by the European Commission’s (EC’s) Horizon 2020 Low Carbon Energy program. Solvents Could Be Game-Changing The […]

Dreams of a future of round-the-clock dispatchable solar energy may have become reality at the Crescent Dunes Solar Energy Project in Nevada.

Mississippi Power’s integrated gasification combined cycle (IGCC) power plant under construction in Kemper County, Miss., will likely be placed in service by November 30, a month later than anticipated. The delay will be costly. Mississippi Power reached a new milestone on September 16, announcing that it had started producing syngas using the second gasifier—gasifier “A”—at […]

As of October 5, the Paris Agreement—the first global agreement on efforts to limit and mitigate the effects of climate change—had been ratified by a sufficient number of countries, representing at least 55% of global greenhouse gas (GHG) emissions, to bring the agreement into force.

Public Service Enterprise Group (PSEG) will close the 620-MW Hudson Generation Station in Jersey City, N.J., and the 632-MW Mercer Generation Station in Hamilton Township, N.J., on June 1, 2017. “The sustained low prices of natural gas have put economic pressure on these plants for some time. In that context, we could not justify the […]

Big or small? Centralized or distributed? The answer, at least for energy storage, may be both, but what that future may be is unclear, if early discussions at the Energy Storage North America (ESNA) conference in San Diego October 4–6 are anything to go by. Speaking on the first night’s opening keynote panel, Colin Cushnie, […]

The Tennessee Valley Authority (TVA) has reached another milestone in its effort to bring Watts Bar Unit 2 into commercial operation: The unit completed its final power ascension test—a 50% load rejection from full power—and safely returned to full power on September 30.
