Signal Hill West Unit: FAQ
- Where is Signal Hill West Unit?
- In Los Angeles 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.

- 6 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
- Who owns Signal Hill West Unit?
- EIA-860M names Signal Hill Petroleum, 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 Signal Hill West Unit LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Signal Hill Petroleum, 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 "Signal Hill West Unit LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
