Owner data does not fully agree across sources.
EIA typically reports the operating utility, while GEM resolves to the financial owner or parent corporation. Both can be correct.

Barkley Powerplant switchyard transformed with delivery and installation of two 90-ton transformers.
Barkley Dam is a dam along the Cumberland River in Kentucky. Its construction along with Kentucky Dam formed the Land Between the Lakes National Recreation Area (LBLNRA) by stopping the flow of the Cumberland and Tennessee Rivers, forming Lake Barkley and Kentucky Lake respectively. It is operated by the United States Army Corps of Engineers.

This plant's balancing authority participates in the Southeast Energy Exchange Market (SEEM). SEEM is a bilateral exchange — no public nodal pricing.
No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
