Georgia Power gas unit leads generation additions in October

Georgia Power’s third 840-MW combined-cycle gas unit at the Jack McDonough station in Cobb County, is the largest power plant to come online during October, according to a monthly report from Federal Energy Regulatory Commission (FERC) staff.

There was more than 1,760 MW of new electric generating capacity brought online during October and more than 1,000 MW of that total is fueled by natural gas, according to the Nov. 13 update from FERC’s Office of Energy Projects.

In Georgia, the Southern (NYSE: SO) subsidiary brought online the third 840-MW unit at the McDonough-Atkinson plant. “The three natural-gas fired units are replacements of the retired coal-fueled units.
