2nd largest plant in Delaware · 492nd nationally
Edge Moor is a oil power plant in Delaware with a nameplate capacity of 710 MW. It generates roughly 222.3k MWh per year — enough to power about 21,170 average U.S. homes.
Its capacity factor of 4% reflects intermittent or peaking operation. At 1613 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 (710 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.
