Mira Loma Peaker: FAQ

Where is Mira Loma Peaker?
In San Bernardino 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.

50 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
Who owns Mira Loma Peaker?

Is this the same as Mira Loma Peaker LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Southern California Edison Co 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 "Mira Loma Peaker LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
