The story behind this New York power plant
Among New York’s 46 oil-fired power plants, Plant No 1 Freeport ranks #31 by electricity produced in 2024. Owned by the Village of Freeport, it sits at 220 West Sunrise Highway in Nassau County and has operated since 1941.
The plant has 2 generators with a combined capacity of 6.0 MW. A megawatt (MW) is a measure of how much power a plant can deliver at one moment. It runs on distillate fuel oil, a refined petroleum liquid, and serves as a standby plant: its role is to be available when extra electricity is needed, rather than to run steadily.
