Weather peril exposure
MIDLOTHIAN ENERGY FACILITY is a 1,734 MW natural gas power plant in Ellis County, TX, operated by MIDLOTHIAN ENERGY LP, commissioned in 2000. Ellis County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.2 of 5 at the 80th national percentile. Hail is the leading peril, rated Relatively High by FEMA at the 84th 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.
