Wilson Dam is a dam on the Tennessee River in Lauderdale and Colbert counties of Alabama, United States. Completed in 1924 by the United States Army Corps of Engineers, it impounds Wilson Lake, and is one of nine Tennessee Valley Authority (TVA) dams on the Tennessee River. It was declared a National Historic Landmark on November 13, 1966, for its role as the first dam to come under the TVA's administration. The dam is named for President Woodrow Wilson.

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.
