The William H. Zimmer Power Station, located near Moscow, Ohio, was a 1.35-gigawatt coal power plant. Planned by Cincinnati Gas and Electric (CG&E), with Columbus & Southern Ohio Electric and Dayton Power & Light (DP&L) as its partners, it was originally intended to be a nuclear power plant. Although once estimated to be 97% complete, poor construction and quality assurance (QA) led to the plant being converted to coal-fired generation. The plant began operations in 1991. Today, the plant is owned and operated by Vistra Corp.

The Acid Rain Program is a market-based initiative taken by the United States Environmental Protection Agency in an effort to reduce overall atmospheric levels of sulfur dioxide and nitrogen oxides, which cause acid rain. The program is an implementation of emissions trading that primarily targets coal-burning power plants, allowing them to buy and sell emission permits according to individual needs and costs. In 2011, the trading program that existed since 1995 was supplemented by four separate trading programs under the Cross-State Air Pollution Rule (CSAPR). On August 21, 2012, the United States Court of Appeals for the District of Columbia issued its Opinion and Order in the appeal of the Cross State Air Pollution Rule (CSAPR) for two independent legal reasons. The stay on CSAPR was lifted in October 2014, allowing implementation of the law and its trading programs to begin.
Coal generated about 22% of the electricity at utility-scale facilities in the United States in 2021, down from 39% in 2014. In 2021, coal supplied 9.5 quadrillion British thermal units (2,800 TWh) of primary energy to electric power plants, which made up 90% of coal's contribution to U.S. energy supply. Utilities buy more than 90% of the coal consumed in the United States. There were over 200 coal powered units across the United States in 2022. Coal plants have been closing since the 2010s due to cheaper and cleaner natural gas and renewables. But environmentalists say that political action is needed to close them faster, to reduce greenhouse gas emissions by the United States to better limit climate change.
