Battery Storage Projects in Colorado: FAQ

How many battery storage projects are in Colorado?
14, with 267 MW of nameplate capacity between them, spread over 5 counties. That is the EIA-860M operating count for 2026-07.
Is there a map of Colorado battery storage projects?
Yes — the map above. Each dot is one battery storage project, sized by nameplate capacity and placed at the coordinates EIA files for it.
Which is the largest battery storage project in Colorado?
Jackson Fuller Energy Storage, at 100 MW. The table is sorted largest first, so the rest follow it.
Is there a battery storage project 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 battery storage projects?
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. EIA technology "Batteries" — grid-connected electrochemical storage of 1 MW and above. 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.
