Mountainview Generating Station: FAQ

Where is Mountainview Generating Station?
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.

1 GW of nameplate capacity across 6 units, as of the EIA-860M release for 2026-07.
Who owns Mountainview Generating Station?
EIA-860M names Southern California Edison Co 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 Mountainview Generating Station 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 "Mountainview Generating Station LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Mountainview Generating Station still running?
