41st largest plant in Pennsylvania · 891st nationally
Brunot Island is a natural gas power plant in Pennsylvania with a nameplate capacity of 365 MW. It generates roughly 105.2k MWh per year — enough to power about 10,023 average U.S. homes.
Its capacity factor of 3% reflects intermittent or peaking operation. At 1370 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (365 MW nameplate × hours in the month). Filled bars are actual net generation reported to EIA Form 923. The gap between them is capacity factor made visible.

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.
