South Field Energy

🔥 Natural GasIPP Non-CHP1,210 MW capacity

6th largest plant in Ohio · 234th nationally

South Field Energy is a natural gas power plant in Ohio with a nameplate capacity of 1,210 MW. It generates roughly 8.3M MWh per year — enough to power about 786,028 average U.S. homes.

Its capacity factor of 78% puts it in the middle range — running steadily but not full-time. At 793 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.
