16th largest plant in Georgia · 501st nationally
Edward L. Addison Generating Plant is a natural gas power plant in Georgia with a nameplate capacity of 701 MW. It generates roughly 200.2k MWh per year — enough to power about 19,062 average U.S. homes.
Its capacity factor of 3% reflects intermittent or peaking operation. At 1344 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.

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.
