EIA-860M names Covanta Honolulu Resource Recovery 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 H Power LLC?

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

Is H Power still running?

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