Document Type: Proceeding Paper

Part of: Waterpower '85


Shoshone Powerplant and Buffalo Bill Dam are located on the Shoshone River approximately 5 miles (8. 1 km) west of Cody, Wyoming. The Powerplant was completed and the first two generating units went on line in 1922. Unit 3 went on line in 1931, and the plant remained operational until 1980 when it was decommissioned because of high maintenance costs. The plant is now on the National Register of Historic Places. In order to meet increasing water requirements, Buffalo Bill Dam is scheduled for modification. In addition to the dam modifications, the powerplant and associated waterways will be renovated. The plant renovation will replace Unit 3 and will restore the remainder of the plant to its 1922 condition. A discussion of the renovation of this unique structure is presented in this paper.
