Massena Energy Facility

🔥 Natural GasIPP Non-CHP104 MW capacity

60th largest plant in New York · 2383rd nationally

Massena Energy Facility is a natural gas power plant in New York with a nameplate capacity of 104 MW. It generates roughly 21.9k MWh per year — enough to power about 2,082 average U.S. homes.

Its capacity factor of 2% reflects intermittent or peaking operation. At 1031 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.

About Natural Gas plants

Natural gas plants are the workhorse of the modern grid. Combined-cycle units achieve very high efficiency and can ramp up and down quickly to balance variable renewables. They emit roughly half the CO₂ per MWh of coal and far less of other pollutants, but they still release upstream methane during fuel extraction.
