Siphon Power Project: FAQ
- Where is Siphon Power Project?
- In Deschutes County, Oregon (OR). 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 Siphon Power Project?
- 5 MW of nameplate capacity across 2 units, as of the EIA-860M release for 2026-07.
- Who owns Siphon Power Project?
- EIA-860M names Central Oregon Irrigation Dist 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 Siphon Power Project LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Central Oregon Irrigation Dist 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 "Siphon Power Project LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
