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.

PUC Avoids Derailing Big Stone II Coal Project
LCG, October 12, 2007--The Minnesota Public Utilities Commission (PUC) yesterday agreed to allow the application to construct two electric transmission lines from the planned coal-fired unit, Big Stone II, to Granite Falls, Minnesota to proceed. Two of the utilities supporting the new power plant, Great River Energy and Southern Minnesota Municipal Power Agency, recently announced their decision to withdraw from the project, placing the future of the generation and transmission projects in doubt. The five co-owners of Big Stone II are now Otter Tail Power Co., Central Minnesota Municipal Power Agency, Heartland Consumers Power District, Missouri River Energy Services and Montana-Dakota Utilities.
As previously proposed, the transmission project was to extend between 140 and 160 miles and to cost $225 million to $275 million. With the withdrawal of the two utilities, the project partners informed the PUC that the Big Stone II power plant capacity may be reduced from a 630-MW to perhaps a 500-MW or 580-MW plant.
The proposed electric generating facility would be sited adjacent to the existing, 450-MW Big Stone facility located near the Minnesota-South Dakota border.
Opponents of the projects had hoped that, with uncertainty hanging over the power plant and its design capacity, the transmission line project would be sent back to square one to restart the approval process, which would have led to significant delays in the projects.
A final decision from the PUC is anticipated in 2008.
