Edwards Sanborn E2: FAQ

Where is Edwards Sanborn E2?
In Kern 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.
How big is Edwards Sanborn E2?
258 MW of nameplate capacity across 2 units, as of the EIA-860M release for 2026-07.
Who owns Edwards Sanborn E2?
EIA-860M names Terra-Gen Operating Co-Hybrid 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 Edwards Sanborn E2 LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Terra-Gen Operating Co-Hybrid 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 "Edwards Sanborn E2 LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Edwards Sanborn E2 still running?
