In context: how this plant compares

At 1,640 MW, Intermountain power station is well above the median coal plant in United States of America (558 MW). Technically it is described as subcritical. Its current lifecycle status is “Mothballed” — so it is not yet, or no longer, generating at full output. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.
