In context: how this plant compares

At 1,444 MW, J K Spruce is well above the median coal plant in United States of America (558 MW). Technically it is described as Steam. Its current lifecycle status is “Announced” — 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.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.
