Project Authorization: | The Congress authorized the Boysen Unit of the Pick Sloan Missouri Basin Program under the Flood Control Act of December 22, 1944, Public Law 534, which approved the general comprehensive plan set forth in Senate Document 191, as revised and coordinated by Senate Document 247, 78th Congress, 2d Session. |
Project Purposes: | The Boysen Unit provides regulation of the streamflow for power generation, irrigation, flood control, sediment retention, fish propagation, and recreation development. |
Plant Purpose: | Power generated at the Boysen Powerplant is fed into the Western Division, Pick-Sloan Missouri Basin Program transmission facilities for use within that division. |
Plant Facts: | An overflow, weir-type spillway controlled by radial gates is located on the right abutment and discharges immediately upstream and left of the Boysen Powerplant. The powerplant has an installed capacity of 15,000 kilowatts developed by two 7,500-kilowatt units operating under an average head of 99 feet. Each unit is served by a 10-foot-diameter steel penstock joined to a common 15-foot diameter steel penstock immediately upstream from the powerplant. The 15-foot-diameter penstock leading from the intake structure to the units was located to utilize the bore of an existing railroad tunnel made available through relocation of the CB&Q Railroad. |
Plant History: | Construction of the powerplant was authorized by the Flood Control Act of December 22, 1944. Construction began in 1947 and was completed in 1952. |
Present Activities: | Design of the replacement CO2 fire suppression system for the two generating units was completed in FY 2002. The contract was awarded in early FY 2003 and will be completed in FY 2005. A contract was awarded in FY 2003 for replacement of the bonnet drain valves and piping on both unit ring seal gates. Work was completed in March 2004.
|
Future Planned Activities: | A replacement wicket gate greasing system was designed in FY 2004 and the new system will be installed in FY 2005.
