MANSFIELD MILL, a 135 MW Natural Gas power plant in De Soto Parish, Louisiana. Operated by IPC-MANSFIELD MILL, commissioned 1981.
How MANSFIELD MILL compares
With 135 MW of capacity, MANSFIELD MILL ranks 29th among the 72 operating power plants Bywatts maps in Louisiana and 20th of the 41 operating Natural Gas plants in the state. It accounts for about 0.9% of Louisiana's operating Natural Gas capacity and 0.5% of all operating capacity in the state. Nationally it is the 622nd-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1981, it is older than 54% of the 72 operating Louisiana plants with a recorded commissioning year.
Under the same EIA plant code, EIA-860 lists 4 generators at the site with 172 MW of nameplate capacity (this page's HIFLD capacity figure is 135 MW). Net generation was 746 GWh in 2024 (a 49% capacity factor), down 16% from 2022. Its generators came online between 1981 and 2019.

Weather peril exposure
MANSFIELD MILL is a 135 MW natural gas power plant in De Soto Parish, LA, operated by IPC-MANSFIELD MILL, commissioned in 1981. De Soto Parish carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.1 of 5 at the 76th national percentile. Lightning is the leading peril, rated Relatively Low by FEMA at the 97th 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.
