LCG, April 13, 2026--The EIA today released an "In-brief Analysis" of U.S. coal-fired generating capacity retirements in 2025. A highlight of the analysis is that, during 2025, the electric power sector retired 2.6 GW of coal-fired generating capacity at four power plants, which is (i) the least since 2010 and (ii) 5.9 GW less than the planned retirement of 8.5 GW at the beginning of 2025.

LCG, April 10, 2026--The U.S. Environmental Protection Agency (EPA) announced yesterday a rule proposing several revisions to the federal regulations governing the disposal of coal combustion residuals (CCR) and the beneficial use of CCR. The EPA designed the rule to encourage resource recovery, allow for site-specific considerations in permitting, and provide regulatory relief while continuing to protect human health and the environment. The EPA will be accepting comments on the rule for 60 days after publication in the Federal Register, and it will also hold an online public hearing on the rule.

AEP Revises Settlement and Agrees to Retire Three Coal-fired Units
LCG, February 26, 2013--A revised settlement agreement between American Electric Power Company (AEP), the U.S. Environmental Protection Agency (EPA), and a coalition of environmental and citizen groups was announced yesterday that will retire three of AEP's coal-fired, electric generating units.
The revised settlement includes the closure of AEP's Tanners Creek Generating Station Unit 4 in Indiana, the Muskingum River Power Plant Unit 5 in Ohio, and the Big Sandy Power Plant Unit 2 in Kentucky, which have a combined generating capacity of 2,011 MW.
Other terms of the revised settlement include AEP paying a total of $6 million to Connecticut, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island and Vermont, plus $2.5 million to citizen groups in Indiana. AEP must also develop 50 MW of wind or solar generating capacity in 2013, plus 150 MW in Indiana or Michigan by 2015.
The revised settlement allows AEP to install a lower cost, sulfur dioxide emission control system at the Rockport coal plant in southern Indiana.
AEP, like other owners of coal-fired power plants, continues to evaluate costly compliance options in response to growing federal regulations, such as the utility mercury and air toxics standards (MATS), driven by the EPA. Uncertainty on near-term emission control project costs, plus future incremental costs to comply with new regulations that may arise, makes it increasingly attractive to retire older coal-fired plants and to invest in new plants fueled with low-cost natural gas.
