The Chickamauga Dam is a hydroelectric dam on the Tennessee River in Chattanooga, Tennessee, United States. The dam is owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s as part of a New Deal era initiative to improve navigation and bring flood control and economic development to the Tennessee Valley. The dam impounds the 36,240-acre (14,670 ha) Chickamauga Lake and feeds into Nickajack Lake. The dam and associated infrastructure were listed on the National Register of Historic Places in 2017.

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.
