As of 2006, R. Gallagher was the dirtiest major power station in the US in terms of sulphur dioxide gas emission rate: it discharged 40.38 pounds (18.32 kg) of SO2 for each MWh of electric power produced that year (50,819 tons of SO2 per year in total).3
Duke Energy shutdown the plant on June 1, 2021,4 earlier than the previously scheduled retirement in 2022. After shutdown Duke Energy will continue the process of closing coal ash basins on site, which could take several years. The Gallagher plant is expected to be dismantled at some point in the future.56
