Second Imperial Geothermal: FAQ

Where is Second Imperial Geothermal?
In Imperial County, California (CA). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.

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