STATE LINE COMBINED CYCLE, a 691 MW Natural Gas power plant in Jasper County, Missouri. Operated by EMPIRE DISTRICT ELECTRIC CO, commissioned 1995.
How STATE LINE COMBINED CYCLE compares
With 691 MW of capacity, STATE LINE COMBINED CYCLE ranks 9th among the 92 operating power plants Bywatts maps in Missouri and 2nd of the 23 operating Natural Gas plants in the state. It accounts for about 13% of Missouri's operating Natural Gas capacity and 3.6% of all operating capacity in the state. Nationally it is the 196th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1995, it is newer than 66% of the 89 operating Missouri plants with a recorded commissioning year. Its operator, EMPIRE DISTRICT ELECTRIC CO, runs 3 operating plants in Missouri totaling 1,086 MW. It shares Jasper County with 2 other operating plants, EMPIRE ENERGY CENTER and CARTHAGE.
EIA-860 lists 4 generators at the site with 691 MW of nameplate capacity, mainly natural gas fired combined cycle technology. Net generation was 2,311 GWh in 2024 (a 38% capacity factor), down 3% from 2022. Its generators came online between 1995 and 2001.

Weather peril exposure
STATE LINE COMBINED CYCLE is a 691 MW natural gas power plant in Jasper County, MO, operated by EMPIRE DISTRICT ELECTRIC CO, commissioned in 1995. Jasper County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.9 of 5 at the 73rd national percentile. Ice storm is the leading peril, rated Very High by FEMA at the 91st 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.
