13th largest plant in West Virginia · 2258th nationally
Axiall Natrium Plant is a natural gas power plant in West Virginia with a nameplate capacity of 116 MW. It generates roughly 667.4k MWh per year — enough to power about 63,565 average U.S. homes.
Its capacity factor of 66% puts it in the middle range — running steadily but not full-time. At 535 lb CO₂/MWh, its emission rate sits below the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (116 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.
