Citing a mounting compliance crunch in America’s coal-fired power sector, the U.S. Environmental Protection Agency (EPA) has finalized new rules extending key deadlines for coal ash cleanup and management, while floating the prospect of a further 12-month delay. The changes address calls from utilities, engineering contractors, and state regulators for more realistic timeframes to assess, […]

As government policies around energy transition continue to evolve, the pace of coal plant retirements in North America has shifted in some regions, slowing in a few cases due to energy reliability concerns.

The Public Service Commission of West Virginia (PSC) approved Appalachian Power Co. (APCo) and Wheeling Power Co.’s (WPCo’s) request to keep the 2,930-MW Amos, 1,320-MW Mountaineer, and 780-MW Mitchell coal-fired power plants operational until at least 2040. APCo and WPCo are electric power subsidiaries of American Electric Power Co. (AEP), which is one of the […]

The Virginia State Corporation Commission (SCC) on Aug. 23 rattled American Electric Power’s (AEP’s) plans to operate the 2.9-GW John Amos and 1.3-GW Mountaineer coal power plants through 2040 when it partly denied cost recovery for expenses that the West Virginia plants need to comply with the federal Steam Electric Effluent Limitations Guidelines (ELG) rule. The […]

American Electric Power (AEP) will shut down or refuel 5.6 GW of its 2020 coal-fired power fleet by 2030 to comply with environmental rules—including recent revisions governing federal coal ash and effluent limitations—and rebalance its portfolio in a bid to meet ambitious climate goals.  The move is bold for the Columbus, Ohio-based generating giant, which […]

The U.S. Environmental Protection Agency (EPA) on July 29 finalized several changes to the regulations for disposal of coal combustion residuals (CCRs), or coal ash, from electric utilities.
