🔥 Natural GasElectric Utility1,288 MW capacity

8th largest plant in Alabama · 207th nationally

Greene County is a natural gas power plant in Alabama with a nameplate capacity of 1,288 MW. It generates roughly 1.4M MWh per year — enough to power about 132,977 average U.S. homes.

Its capacity factor of 12% reflects intermittent or peaking operation. At 1257 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.
