Green Country Power Station: FAQ
- Where is Green Country Power Station?

- Who owns Green Country Power Station?
- EIA-860M names Public Service Co of Oklahoma 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 Green Country Power Station LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Public Service Co of Oklahoma 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 "Green Country Power Station LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
