Weather peril exposure
TENNESSEE EASTMAN OPERATIONS is a 194 MW coal power plant in Sullivan County, TN, operated by EASTMAN CHEMICAL CO-TN OPS, commissioned in 1936. Sullivan County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.2 of 5 at the 4th national percentile. Earthquake is the leading peril, rated Relatively Low by FEMA at the 78th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a coal plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
