The story behind this New York power plant
New York has 100 natural gas plants in this category, and the Indeck Olean Energy Center, on Moore Ave. in Olean, ranks #56 of 100 by 2024 electricity produced. It’s a combined cycle plant, meaning it uses the hot exhaust from burning natural gas to make extra power instead of letting that heat go to waste. It has been running since 1994, with two generators and a rated capacity of 90.6 MW (megawatts, a measure of the most power it can deliver at once).
In 2024 it produced 34.5 gigawatt-hours (a unit of electricity over time, where one gigawatt-hour is a million kilowatt-hours), enough to power about 3,500 homes. The plant draws its water from wells, and National Grid is the utility serving the area.
Generation profile
The plant can produce 91 megawatts of electricity at once, across 2 generating units. In 2024 it produced 34.5 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.
