The Sammis coal power plant along the Ohio River in Jefferson County will close its remaining units at the end of 2028, owner Energy Harbor notified state officials in a letter earlier this month.

The Oct. 12 letter, sent to the Ohio Environmental Protection Agency, didn’t explicitly state why the plant was shutting down. However, the letter noted that new federal wastewater pollution discharge limits for coal power plants go into effect at the end of 2025.

Energy Harbor already closed four of the plant’s seven units last year; the remaining three units will close Dec. 31, 2028, according to the letter. A copy of the letter was provided to by the Sierra Club, which obtained it from the Ohio EPA.

Ohio EPA spokesman James Lee confirmed to that the agency received the letter. has reached out to Energy Harbor for comment.

Three years ago, Energy Harbor — then a FirstEnergy Corp. subsidiary called FirstEnergy Solutions — announced plans to fully close the 61-year-old power plant by 2022. But those plans were reversed in 2019 with the passage of the scandal-ridden House Bill 6.
