Generating units
| Unit | Technology | Nameplate | Summer | Online | Status |
|---|---|---|---|---|---|
| 4 | Natural Gas Steam Turbine | 381 MW | 310 MW | 1968 | Operating |
| 7 | Natural Gas Fired Combined Cycle | 255 MW | 240 MW | 2015 | Operating |

| 6 | Natural Gas Fired Combined Cycle | 185 MW | 168 MW | 2015 | Operating |
Nameplate is the maximum rated output; summer capacity is what the unit can reliably deliver on a hot day, which is typically lower.

About this data
From EIA’s inventory of operable generators, May 2026 release. Capacity is nameplate — the maximum rated output of the equipment, not what the plant actually generates over a year, which depends on how often it runs. A 1,006 MW solar plant and a 1,006 MW nuclear plant have the same entry here and produce very different amounts of electricity.
“In service since” is the earliest in-service date among the units still listed, so a site rebuilt around newer equipment can read as younger than the site itself. All Colorado power plants · What Colorado actually generates
