59th largest plant in Alaska · 6121st nationally
Tesoro Kenai Cogeneration Plant is a natural gas power plant in Alaska with a nameplate capacity of 8.6 MW. It generates roughly 69.2k MWh per year — enough to power about 6,591 average U.S. homes.
Its capacity factor of 92% means it runs nearly around-the-clock as baseload generation. At 583 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.
