I25 Battery Storage: FAQ
- Where is I25 Battery Storage?
- 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 I25 Battery Storage?
- 4 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
- Who owns I25 Battery Storage?
- EIA-860M names United Power, Inc 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 I25 Battery Storage LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — United Power, Inc 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 "I25 Battery Storage LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
