34th largest plant in New Jersey · 4111th nationally
Princeton University Cogeneration is a natural gas power plant in New Jersey with a nameplate capacity of 32.1 MW. It generates roughly 54.0k MWh per year — enough to power about 5,146 average U.S. homes.
Its capacity factor of 19% reflects intermittent or peaking operation. At 476 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.
