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.

AES Announces New Battery Storage Project for PJM
LCG, June 19, 2013--AES Energy Storage, a subsidiary of AES Corporation, yesterday announced plans to deliver 40 MW of new, advanced energy storage resources to the PJM Interconnection. The new storage capacity will be located at Dayton Power and Light's (DP&L) Tait Generating Station, south of Dayton, Ohio. The storage resource can displace power generation from aging, inefficient power plants and potentially reduce overall system emissions. The project is expected to be operational in September 2013.
The AES storage resource is a battery array designed to provide frequency regulation service to the PJM market and deliver a new energy technology to Ohio. The 40 MW storage resource will consist of 24 MW from AES inventory plus 16 MW from an existing AES facility that will be relocated to Ohio.
The President of AES Energy Storage stated, "We've designed our business model in a way that allows us to quickly evaluate and respond to changing market needs. We can make decisions on where we locate battery storage to optimize service across markets. Physically moving an asset to where it?s needed most hasn't been possible with traditional power generation and load resources, so it's exciting to be able to do this with energy storage assets."
DP&L's Tait Station is a peaking facility. The storage project will connect through the station and will utilize an independent agreement with PJM.
AES recently surpassed 400,000 MWH of service within PJM at its Laurel Mountain facility, which also utilizes AES' patented control system designed to most efficiently control the battery array consistent with the local market dispatch rules.
