St. Charles Power Station (La)

🔥 Natural GasElectric Utility1,000 MW capacity

9th largest plant in Louisiana · 317th nationally

St. Charles Power Station (La) is a natural gas power plant in Louisiana with a nameplate capacity of 1,000 MW. It generates roughly 5.1M MWh per year — enough to power about 481,854 average U.S. homes.

Its capacity factor of 58% puts it in the middle range — running steadily but not full-time. At 845 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.

About Natural Gas plants

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.
