Bridgeport Station

🔥 Natural GasIPP Non-CHP576 MW capacity

8th largest plant in Connecticut · 648th nationally

Bridgeport Station is a natural gas power plant in Connecticut with a nameplate capacity of 576 MW. It generates roughly 2.9M MWh per year — enough to power about 280,483 average U.S. homes.

Its capacity factor of 58% puts it in the middle range — running steadily but not full-time. At 797 lb CO₂/MWh, its emission rate sits below 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.
