110th largest plant in California · 1357th nationally
Roseville Energy Park is a natural gas power plant in California with a nameplate capacity of 225 MW. It generates roughly 343.6k MWh per year — enough to power about 32,720 average U.S. homes.
Its capacity factor of 17% reflects intermittent or peaking operation. At 987 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 (225 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.
