Buffalo Bill Dam is a concrete arch-gravity dam on the Shoshone River in the U.S. state of Wyoming. Originally 325 feet (99 m), it was the tallest dam in the world when it opened in 1910; a 25-foot (7.6 m) extension was added in 1992 in one of the numerous changes and improvements to the structure and its support facilities, which include two full-time power generators and two seasonal operations added between 1920 and 1994, and a 2.8-mile (4.5 km) irrigation tunnel completed in 1939.
Read more on WikipediaThe Shoshone hydroelectric plant is located in Park County, Wyoming. It has a total capacity of 3 MW and began operating in 1922. The plant is owned and operated by the U.S. Bureau of Reclamation. It utilizes conventional hydroelectric technology with a single generator and its primary fuel source is water (WAT).
In the most recent year of data, the Shoshone plant generated 17,671 MWh of electricity, achieving a capacity factor of 67.0%. The plant operates within the Western Electricity Coordinating Council (WECC) NERC region and is under the balancing authority of the Western Area Power Administration UGP West. Shoshone ranks as the 12th largest power plant in Wyoming out of 16, and nationally it ranks 1079 out of 1464 plants.

This plant is in a bilateral market territory without organized wholesale pricing. Nodal pricing data is not available.
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.
