Weather peril exposure
RUMFORD COGENERATION is a 103 MW biomass power plant in Oxford County, ME, operated by NEWPAGE CORPORATION, commissioned in 1990. Oxford County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.0 of 5 at the 26th national percentile. Lightning is the leading peril, rated Relatively Moderate by FEMA at the 96th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a biomass plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
