40th largest plant in Tennessee · 3575th nationally
Domtar Kingsport Mill is a natural gas power plant in Tennessee with a nameplate capacity of 50.0 MW. It generates roughly 127.6k MWh per year — enough to power about 12,153 average U.S. homes.
Its capacity factor of 29% reflects intermittent or peaking operation.
Ghost bars are each month's theoretical maximum (50.0 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.
