Seneca Energy: FAQ

Where is Seneca Energy?
In Seneca 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.
How big is Seneca Energy?
18 MW of nameplate capacity across 18 units, as of the EIA-860M release for 2026-07.
Who owns Seneca Energy?
EIA-860M names Seneca Energy II 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 Seneca Energy LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Seneca Energy II 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 "Seneca Energy LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Seneca Energy still running?
EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
