Power Plants in New York

New York's generating fleet holds 44.7 GW of capacity as of May 2026, ranking it sixth among the fifty states and the District of Columbia by total size. This is capacity — what the equipment could produce running flat out — not generation; a megawatt of solar and a megawatt of nuclear appear the same here and produce very different amounts of electricity over a year. The fleet spans 1,152 plants, though 1,145 are in service. Natural gas dominates at 54.7% of capacity across 103 plants, followed by hydro at 13.2% across 165 plants. Other fuels, solar, wind, and nuclear together make up the remainder, with nuclear at 7.6% across three plants, solar at 7.1% across 716 plants, wind at 6.7% across 34 plants, and a category labelled Other at 10.1% across 99 plants. Battery storage adds 0.6% across 32 plants.

The largest plant is Robert Moses Niagara, a hydro station with 2,429 MW, followed by Ravenswood, a natural gas plant with 2,096 MW, and Nine Mile Point Nuclear Station with 1,901 MW. Oswego Harbor Power, using other fuels, holds 1,804 MW, and Northport, another natural gas plant, holds 1,564 MW. The fleet's oldest plant still listed came online in January 1927: Allens Falls. The newest is Baron Winds II, which came online in May 2026. The largest plants span from 1961, when Robert Moses Niagara first operated, through the decades to the present.
