MEXICO, a 61 MW Oil power plant in Audrain County, Missouri. Operated by UNION ELECTRIC CO - (MO), commissioned 1978.
How MEXICO compares
With 61 MW of capacity, MEXICO ranks 37th among the 92 operating power plants Bywatts maps in Missouri and 5th of the 33 operating Oil plants in the state. It accounts for about 4.3% of Missouri's operating Oil capacity and 0.3% of all operating capacity in the state. Nationally it is the 63rd-largest of the 544 operating Oil plants in the database. Commissioned in 1978, it is newer than 46% of the 89 operating Missouri plants with a recorded commissioning year. Its operator, UNION ELECTRIC CO - (MO), runs 11 operating plants in Missouri totaling 6,645 MW. It shares Audrain County with 2 other operating plants, AUDRAIN GENERATING STATION and MJMEUC GENERATING STATION #1.
EIA-860 lists 1 generator at the site with 61 MW of nameplate capacity, all petroleum liquids technology. Net generation was 0.767 GWh in 2024 (a 0.1% capacity factor).
Grid neighborhood
The nearest named substation is AUDRAIN (345 kV), about 19.4 miles away. Another 4 operating power plants totaling 1,029 MW sit within 25 miles; the largest is AUDRAIN GENERATING STATION (814 MW, Natural Gas).

Weather peril exposure
MEXICO is a 61 MW oil power plant in Audrain County, MO, operated by UNION ELECTRIC CO - (MO), commissioned in 1978. Audrain County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.5 of 5 at the 62nd national percentile. Earthquake is the leading peril, rated Relatively Low by FEMA at the 83rd percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to an oil plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
