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.

Lake Michigan Silt Closes AEP's Cook Nuke
LCG, Aug. 30, 2001--American Electric power Co. said this morning that the 1,100 megawatt Unit 2 of its Cook nuclear power plant at Benton Harbor, Mich., was being taken off line because of the intrusion of Lake Michigan silt into its cooling water systems."The silt was drawn in by plant water intake pipes and degraded cooling water systems required for plant safety equipment and back-up power sources," AEP said in a statement.Silty water is a fine abrasive and can literally grind down the moving parts of a system in which it circulates. AEP said Unit 1 at Cook, a twin of Unit 2, was taken off line on Monday to replace a circulating water pump discharge valve. The company did not say silt was what made the replacement necessary but did say that silt intrusion affects the cooling water systems for both units.Three huge pipes, each 16 feet across, bring water from one-half mile out in Lake Michigan into the plant. It is not surprising that silt -- and an occasional boat -- would find its way into the plant's systems.AEP was unable to say how long the units would be shut down, but said return-to-service schedules for both units will be established following an investigation to determine the cause of the silt intrusion.
