Rocky Mountain Energy Center: FAQ

Where is Rocky Mountain Energy Center?
In Weld County, Colorado (CO). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.
How big is Rocky Mountain Energy Center?

Who owns Rocky Mountain Energy Center?
EIA-860M names Public Service Co of Colorado as the reporting entity. That is the operator of record on the survey, which is not always the ultimate owner.
Is this the same as Rocky Mountain Energy Center LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Public Service Co of Colorado here — not the project company that holds the asset. Project companies are commonly registered as an LLC carrying the plant's name, so a search for "Rocky Mountain Energy Center LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Rocky Mountain Energy Center still running?
