Siphon Drop Power Plant: FAQ

Where is Siphon Drop Power Plant?
In Imperial County, California (CA). 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 Drop Power Plant?
4 MW of nameplate capacity across 2 units, as of the EIA-860M release for 2026-07.
Who owns Siphon Drop Power Plant?
EIA-860M names Yuma County Water User's Association 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 Drop Power Plant LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Yuma County Water User's Association 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 Drop Power Plant LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Siphon Drop Power Plant still running?
