EIA-860M names Alliance NYGT, 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 Hillburn LLC?

Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Alliance NYGT, 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 "Hillburn LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.

Is Hillburn still running?

EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
