Natural Gas Power Plants in Colorado: FAQ
- How many natural gas power plants are in Colorado?
- 30, with 9 GW of nameplate capacity between them, spread over 13 counties. That is the EIA-860M operating count for 2026-07.
- Is there a map of Colorado natural gas power plants?
- Yes — the map above. Each dot is one natural gas power plant, sized by nameplate capacity and placed at the coordinates EIA files for it.
- Which is the largest natural gas power plant in Colorado?
- Fort St Vrain, at 1 GW. The table is sorted largest first, so the rest follow it.
- Is there a natural gas power plant near me in Colorado?
- The county roll-up below groups every plant by county, which is the quickest way to find the one closest to a given town.
- Which grid operator runs Colorado's natural gas power plants?
- No single ISO or RTO covers most of them. EIA files each plant against its own balancing authority, which in Colorado is largely a vertically integrated utility rather than an organised market.
- How current is this, and what is left out?
- EIA-860M for 2026-07. Combined cycle, combustion turbine, steam turbine, internal combustion and other gas-fired units. Plants below 1 MW are not surveyed by EIA and so are absent; retirements and additions after 2026-07 arrive with the next monthly release.
