3rd largest plant in New Hampshire · 607th nationally
Newington Energy Center is a natural gas power plant in New Hampshire with a nameplate capacity of 606 MW. It generates roughly 832.6k MWh per year — enough to power about 79,291 average U.S. homes.
Its capacity factor of 16% reflects intermittent or peaking operation. At 902 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 (606 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.
