The story behind this New York power plant
New York has 100 natural gas plants in this category, and S A Carlson in Jamestown ranks #57 of 100 by 2024 electricity produced. Owned by the Jamestown Board of Public Util, it began operating in 1951 and draws cooling water from the Chadakoin River.
The plant has 3 generators with a capacity of 96.3 MW, meaning the most power it can supply at one moment. In 2024 it produced 33.5 gigawatt-hours, a measure of electricity over time, which is about 3,400 homes’ worth of yearly use. It pairs a combustion turbine, which spins on hot gas from burning fuel, with a steam turbine, which spins on steam.
Generation profile
The plant can produce 96 megawatts of electricity at once, across 3 generating units. In 2024 it produced 33.5 gigawatt-hours in total, which works out to about 4% of what it could have produced running flat out all year — the pattern of a plant that runs only during periods of high demand.
