The story behind this New York power plant
New York has 100 natural gas plants in this category, and Allegany Cogen in Fillmore ranks #74 of 100 by 2024 electricity produced. It began operating in 1994 and uses a natural gas fired combined cycle design, meaning it captures exhaust heat from burning gas to make a second round of electricity. It draws water from the Genesee River and has two generators with a capacity of 67.0 MW, which is the most power it could send out at one moment.
In 2024 it produced 15.5 gigawatt-hours (15,549 MWh), a measure of energy over time that is about 1,600 homes’ worth of electricity for a year. Its output is modest next to its full capacity, a pattern common for plants that run when needed.
Generation profile
The plant can produce 67 megawatts of electricity at once, across 2 generating units. In 2024 it produced 15.5 gigawatt-hours in total, which works out to about 3% of what it could have produced running flat out all year — the pattern of a plant that runs only during periods of high demand.
