BRUNOT ISLAND, a 416 MW Natural Gas power plant in Allegheny County, Pennsylvania. Operated by NRG POWER MIDWEST LP, commissioned 1972.

How BRUNOT ISLAND compares

With 416 MW of capacity, BRUNOT ISLAND ranks 30th among the 170 operating power plants Bywatts maps in Pennsylvania and 12th of the 28 operating Natural Gas plants in the state. It accounts for about 3.9% of Pennsylvania's operating Natural Gas capacity and 1.1% of all operating capacity in the state. Nationally it is the 367th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1972, it is older than 77% of the 168 operating Pennsylvania plants with a recorded commissioning year. Its operator, NRG POWER MIDWEST LP, runs 2 operating plants in Pennsylvania totaling 771 MW. It shares Allegheny County with 5 other operating plants, including ALLEGHENY ENERGY UNITS 3 4 & 5 and FIRSTENERGY ALLEGHENY ENERGY UNITS 1 & 2.

EIA-860 lists 5 generators at the site with 365 MW of nameplate capacity, mainly natural gas fired combined cycle technology (this page's HIFLD capacity figure is 416 MW). Net generation was 54.1 GWh in 2024 (a 1.7% capacity factor). Its generators came online between 1972 and 1974.

Weather peril exposure

BRUNOT ISLAND is a 416 MW natural gas power plant in Allegheny County, PA, operated by NRG POWER MIDWEST LP, commissioned in 1972. Allegheny County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.0 of 5 at the 1st national percentile. Riverine flooding is the leading peril, rated Very High by FEMA at the 66th 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.
