1705th largest plant in California · 12726th nationally
Transamerica Pyramid is a natural gas power plant in California with a nameplate capacity of 1.0 MW. It generates roughly 525 MWh per year — enough to power about 50 average U.S. homes.
Its capacity factor of 6% reflects intermittent or peaking operation. At 657 lb CO₂/MWh, its emission rate sits below 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.
