1251st largest plant in California · 9652nd nationally
San Antonio Regional Hospital is a natural gas power plant in California with a nameplate capacity of 2.7 MW. It generates roughly 10.7k MWh per year — enough to power about 1,023 average U.S. homes.
Its capacity factor of 45% puts it in the middle range — running steadily but not full-time. At 1304 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.
