Havana Power Station was a 488-MW facility with one coal-fired unit first built in 1978, located in Havana, Illinois in Mason County. The plant was owned by Dynegy. In 2018 Dynegy merged with Vistra Energy, who closed the facility in 2019. Havana had six ash ponds, four of which are lined, regulated under the CCR rule. Dynegy settled with the Department of Justice, Environmental Protection Agency, and the State of Illinois in 2005 after violating Clean Air Act permitting provisions. The settlement most notably included the installation of $500 million worth of pollution control equipment. Baldwin Power Station, Hennepin Power Station, Vermilion Power Station, and Wood River Station were also involved in this settlement.
Havana Power Station is listed among the U.S. EPA's proven damage cases, indicating that it has polluted groundwater or surface water at levels which threaten human health and the environment.
