DAHLBERG, a 919 MW Natural Gas power plant in Jackson County, Georgia. Operated by SOUTHERN POWER CO, commissioned 2000.
How DAHLBERG compares
With 919 MW of capacity, DAHLBERG ranks 12th among the 104 operating power plants Bywatts maps in Georgia and 6th of the 26 operating Natural Gas plants in the state. It accounts for about 6.2% of Georgia's operating Natural Gas capacity and 2.6% of all operating capacity in the state. Nationally it is the 114th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2000, it is newer than 70% of the 101 operating Georgia plants with a recorded commissioning year. Its operator, SOUTHERN POWER CO, runs 3 operating plants in Georgia totaling 2,859 MW.
EIA-860 lists 10 generators at the site with 919 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 229 GWh in 2024 (a 2.8% capacity factor). Its generators came online between 2000 and 2001.

Weather peril exposure
DAHLBERG is a 919 MW natural gas power plant in Jackson County, GA, operated by SOUTHERN POWER CO, commissioned in 2000. Jackson County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.8 of 5 at the 46th national percentile. Lightning is the leading peril, rated Relatively Moderate by FEMA at the 85th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
