Kapaia Power Station: FAQ
- Where is Kapaia Power Station?
- In Kauai County, Hawaii (HI). 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 Kapaia Power Station?
- 39 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
- Who owns Kapaia Power Station?
- EIA-860M names Kauai Island Utility Cooperative 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 Kapaia Power Station LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Kauai Island Utility Cooperative 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 "Kapaia Power Station LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
- Is Kapaia Power Station still running?
