4th largest plant in Maine · 1146th nationally
Rumford Power Llc is a natural gas power plant in Maine with a nameplate capacity of 275 MW. It generates roughly 403.4k MWh per year — enough to power about 38,420 average U.S. homes.
Its capacity factor of 17% reflects intermittent or peaking operation. At 872 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 (275 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.
