Boone Dam is a hydroelectric and flood control dam on the South Fork Holston River on the border between Sullivan County and Washington County in the U.S. state of Tennessee. It is one of three dams on the South Fork Holston owned and operated by the Tennessee Valley Authority, which built the dam in the early 1950s as part of greater efforts to control flooding in the Tennessee River watershed. The dam impounds the 4,500-acre (1,800 ha) Boone Lake, and its tailwaters are part of Fort Patrick Henry 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.
