How CARBON compares
It was retired in 2015 according to EIA-860, so it is not counted in Utah's operating fleet. Its operator, PACIFICORP, runs 11 operating plants in Utah totaling 4,139 MW. It shares Carbon County with one other operating plant, SUNNYSIDE COGEN ASSOCIATES.
Grid neighborhood
The nearest named substation is CARBON (138 kV), about 0.1 miles away; the closest transmission line found within 10 miles is a 230 kV line owned by PACIFICORP, under 0.1 miles away.
Computed by Bywatts from HIFLD power plant, substation and transmission line records and EIA-860 retirement records; distances are straight-line. Sources and methodology
Weather peril exposure
CARBON is a retired 189 MW coal power plant in Carbon County, UT, formerly operated by PACIFICORP. Carbon County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.1 of 5 at the 2nd national percentile. Earthquake is the leading peril, rated Relatively Low by FEMA at the 85th 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.
