FORTISTAR NORTH TONAWANDA, a 55 MW Natural Gas power plant in Niagara County, New York. Operated by NORTH AMERICAN ENERGY SERVICES, commissioned 1993.
How FORTISTAR NORTH TONAWANDA compares
With 55 MW of capacity, FORTISTAR NORTH TONAWANDA ranks 86th among the 320 operating power plants Bywatts maps in New York and 50th of the 68 operating Natural Gas plants in the state. It accounts for about 0.3% of New York's operating Natural Gas capacity and 0.1% of all operating capacity in the state. Nationally it is the 792nd-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1993, it is newer than 69% of the 312 operating New York plants with a recorded commissioning year. It shares Niagara County with 7 other operating plants, including ROBERT MOSES NIAGARA and LEWISTON NIAGARA.
EIA-860 lists 2 generators at the site with 66 MW of nameplate capacity, all natural gas fired combined cycle technology (this page's HIFLD capacity figure is 55 MW). Net generation was 289 GWh in 2024 (a 50% capacity factor), about 5 times its 2022 output.

Weather peril exposure
FORTISTAR NORTH TONAWANDA is a 55 MW natural gas power plant in Niagara County, NY, operated by NORTH AMERICAN ENERGY SERVICES, commissioned in 1993. Niagara County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.1 of 5 at the 2nd national percentile. Riverine flooding is the leading peril, rated Relatively Moderate by FEMA at the 68th 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.
