6th largest plant in Connecticut · 571st nationally
New Haven Harbor is a oil power plant in Connecticut with a nameplate capacity of 642 MW. It generates roughly 21.1k MWh per year — enough to power about 2,007 average U.S. homes.
Its capacity factor of 0% reflects intermittent or peaking operation. At 2886 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 (642 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.

Oil-fired plants typically run only during peak demand or grid emergencies because oil is expensive compared to gas and coal. They have the highest CO₂ emissions per MWh of any common generation technology.
