Site description

Georgia Power Company’s Plant McDonough-Atkinson was a 598-MW coal plant in Smyrna, Georgia, near the Coosa River in Cobb County. McDonough-Atkinson opened in 1941 and retired its two coal-fired units in 2011 and 2012. They were replaced with three natural gas-fired units in 2012. The plant operated three active disposal areas: Ash Pond Units 1, 2, and Combined Ash Pond Unit 3 and 4.
