82nd largest plant in Texas · 655th nationally
Harrison County Power Project is a natural gas power plant in Texas with a nameplate capacity of 570 MW. It generates roughly 3.2M MWh per year — enough to power about 309,165 average U.S. homes.
Its capacity factor of 65% puts it in the middle range — running steadily but not full-time. At 854 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 (570 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.
