Vernon Dam: FAQ

Where is Vernon Dam?
In Windham County, Vermont (VT). 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 Vernon Dam?
36 MW of nameplate capacity across 10 units, as of the EIA-860M release for 2026-07.
Who owns Vernon Dam?
EIA-860M names Great River Hydro, 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 Vernon Dam LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Great River Hydro, 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 "Vernon Dam LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Vernon Dam still running?
EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
