SILVER CREEK, a 251 MW Natural Gas power plant in Jefferson Davis County, Mississippi. Operated by SOUTH MISSISSIPPI EL PWR ASSN, commissioned 2003.
How SILVER CREEK compares
With 251 MW of capacity, SILVER CREEK ranks 18th among the 37 operating power plants Bywatts maps in Mississippi and 13th of the 21 operating Natural Gas plants in the state. It accounts for about 2.7% of Mississippi's operating Natural Gas capacity and 1.6% of all operating capacity in the state. Nationally it is the 500th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2003, it is newer than 68% of the 35 operating Mississippi plants with a recorded commissioning year. Its operator, SOUTH MISSISSIPPI EL PWR ASSN, runs 6 operating plants in Mississippi totaling 2,209 MW.
EIA-860 lists 3 generators at the site with 251 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 428 GWh in 2024 (a 19% capacity factor). Its generators came online between 2003 and 2005.
Grid neighborhood
The closest transmission line found within 10 miles is a 115 kV line, under 0.1 miles away. One other operating power plant sits within 25 miles: GEORGIA-PACIFIC MONTICELLO PAPER (65 MW, Biomass).

Weather peril exposure
SILVER CREEK is a 251 MW natural gas power plant in Jefferson Davis County, MS, operated by SOUTH MISSISSIPPI EL PWR ASSN, commissioned in 2003. Jefferson Davis County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.4 of 5 at the 86th national percentile. Lightning is the leading peril, rated Relatively Low by FEMA at the 98th 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.
