32nd largest plant in South Carolina · 2433rd nationally
Cherokee County Cogen is a natural gas power plant in South Carolina with a nameplate capacity of 101 MW. It generates roughly 116.4k MWh per year — enough to power about 11,086 average U.S. homes.
Its capacity factor of 13% reflects intermittent or peaking operation. At 883 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (101 MW nameplate × hours in the month). Filled bars are actual net generation reported to EIA Form 923. The gap between them is capacity factor made visible.

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.
