Site description

Joppa Power Station is a 1,100-MW facility with six coal-fired units located in Joppa, Illinois in Massac County, first built in 1953 on the bank of the Ohio River. Joppa was previously owned and operated by Ameren, until it was bought by Dynegy in 2013. In 2018 Dynegy merged with Vistra Energy, who announced in 2021 that the facility would be closed by September 2022. Waste is disposed of in a landfill and ash pond, regulated by the CCR rule. According to Environment Illinois, Joppa is one of the top five carbon polluters in Illinois.
