Stillwater Hydro Electric Project: FAQ

Where is Stillwater Hydro Electric Project?
In Saratoga County, New York (NY). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.

Who owns Stillwater Hydro Electric Project?
EIA-860M names GR Catalyst One, 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 Stillwater Hydro Electric Project LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — GR Catalyst One, 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 "Stillwater Hydro Electric Project LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
