Sun Valley Storage: FAQ
- Where is Sun Valley Storage?
- In Hill County, Texas (TX). 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 Sun Valley Storage?
- 123 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
- Who owns Sun Valley Storage?
- EIA-860M names Sun Valley Storage LLC 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 Sun Valley Storage LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Sun Valley Storage LLC 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 "Sun Valley Storage LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
