27th largest plant in Montana · 3224th nationally
Yellowstone Energy Lp is a oil power plant in Montana with a nameplate capacity of 68.0 MW. It generates roughly 490.8k MWh per year — enough to power about 46,739 average U.S. homes.
Its capacity factor of 82% means it runs nearly around-the-clock as baseload generation. At 1840 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 (68.0 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.
