Sagebrush Solar 2 ESS 40: FAQ

Where is Sagebrush Solar 2 ESS 40?
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.

Who owns Sagebrush Solar 2 ESS 40?

Is this the same as Sagebrush Solar 2 ESS 40 LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Terra-Gen Operating Co-BESS 2 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 "Sagebrush Solar 2 ESS 40 LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
