Southwestern Bell Telephone: FAQ
- Where is Southwestern Bell Telephone?
- In St Louis City County, Missouri (MO). 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 Southwestern Bell Telephone?
- 17 MW of nameplate capacity across 7 units, as of the EIA-860M release for 2026-07.
- Who owns Southwestern Bell Telephone?
- EIA-860M names AT&T 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 Southwestern Bell Telephone LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — AT&T 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 "Southwestern Bell Telephone LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
