The story behind this New York power plant
East Hampton’s oil-fired plant is one of 46 in New York, and it ranks fifth among them by how much electricity it produced in 2024. It generated 11.6 gigawatt-hours, which is a measure of total electricity produced over time, enough to supply about 1,200 homes. It sits on Cove Hollow Road and has run since 1962.
The plant burns distillate fuel oil, a refined liquid fuel, in four generators with a combined capacity of 27.3 MW, meaning the most power it can deliver at one moment. National Grid Generation LLC owns it, and it serves customers of PSEG Long Island.
Generation profile
The plant can produce 27 megawatts of electricity at once, across 4 generating units. In 2024 it produced 11.6 gigawatt-hours in total, which works out to about 5% of what it could have produced running flat out all year — the pattern of a plant that runs only during periods of high demand.
