🔥 Natural GasElectric Utility1,739 MW capacity

4th largest plant in California · 118th nationally

Haynes is a natural gas power plant in California with a nameplate capacity of 1,739 MW. It generates roughly 2.5M MWh per year — enough to power about 242,825 average U.S. homes.

Its capacity factor of 17% reflects intermittent or peaking operation. At 929 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.
