Lightning Dock Geothermal: FAQ
- Where is Lightning Dock Geothermal?
- In Hidalgo County, New Mexico (NM). 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 Lightning Dock Geothermal?

- Who owns Lightning Dock Geothermal?
- EIA-860M names Lightning Dock Geothermal HI-01, 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 Lightning Dock Geothermal LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Lightning Dock Geothermal HI-01, 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 "Lightning Dock Geothermal LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
