Seminole (OK): FAQ
- Where is Seminole (OK)?
- In Seminole County, Oklahoma (OK). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.

- Who owns Seminole (OK)?

- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Oklahoma Gas & Electric 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 "Seminole (OK) LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
