238th largest plant in Texas · 1340th nationally
Leon Creek is a natural gas power plant in Texas with a nameplate capacity of 230 MW. It generates roughly 223.2k MWh per year — enough to power about 21,256 average U.S. homes.
Its capacity factor of 11% reflects intermittent or peaking operation. At 1216 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.

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.
