69th largest plant in Alabama · 5400th nationally
W&t Onshore Treating Facility (Otf) is a natural gas power plant in Alabama with a nameplate capacity of 12.0 MW. It generates roughly 47.6k MWh per year — enough to power about 4,536 average U.S. homes.
Its capacity factor of 45% puts it in the middle range — running steadily but not full-time. At 619 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 (12.0 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.
