210th largest plant in California · 2142nd nationally
Ivanpah 1 is a solar power plant in California with a nameplate capacity of 126 MW. It generates roughly 228.9k MWh per year — enough to power about 21,802 average U.S. homes.
Its capacity factor of 21% reflects intermittent or peaking operation. At 229 lb CO₂/MWh, its emission rate sits below the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (126 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.

Utility-scale solar farms convert sunlight directly into electricity using photovoltaic panels. They produce zero direct emissions and have no fuel cost, but generation is variable — peaking at midday and falling to zero at night. Capacity factors typically run 18–28% in good locations.
