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.
Is Southwestern Bell Telephone still running?
