The story behind this New York power plant
New York has 100 natural gas plants, and the Joseph J Seymour Power Project in Brooklyn ranks #38 of 100 by 2024 electricity produced. It is owned by the New York Power Authority and began operating in 2001. Its two combustion turbines (engines that burn natural gas to spin a generator, much like a jet engine) have a combined capacity of 94.0 MW, which is the most power the plant can send out at any one moment.
In 2024 it generated 104.2 gigawatt-hours of electricity, a unit of energy equal to about 10,000 homes. It ran at roughly 13 percent of its full potential, a pattern typical of plants that switch on when demand rises and rest the rest of the time.
Generation profile
The plant can produce 94 megawatts of electricity at once, across 2 generating units. In 2024 it produced 104.2 gigawatt-hours in total, which works out to about 13% of what it could have produced running flat out all year — the pattern of a plant that runs only during periods of high demand.
