History
Transformer KRA was replaced in fiscal year 1996. Outlet tube No.2 was repaired in 2001. Governor and the station service transformer were replaced in 2002 and 2003 respectively. Generator was shut down during the winter of 2002-2003 due to lack of water. Unit was uprated to 31,500 kilowatts in 2004.
The Colorado River Storage Project provides for the comprehensive development of the Upper Colorado River Basin. The project furnishes the long-term regulatory storage needed to permit States in the upper basin to meet their flow obligation at Lees Ferry, Arizona, as defined in the Colorado River Compact and still use their apportioned water.
Congress authorized construction of four storage units of the Colorado River Storage Project and 11 participating projects on April 11, 1956, under Public Law 485, 84th Congress, 70 Stat. 105. Additional projects have been added since the original legislation was adopted.
Plan
Generation of hydroelectric power for use in the project. The Crystal Powerplant was completed in 1978. It initially had a generating capacity of 28,000 kilowatts from one unit driven by a 39,000-horsepower hydraulic turbine. It is connected to the main Colorado River Storage Project transmission system at the Curecanti substation by a 115-kilovolt line. Transformer KRA was replaced in fiscal year 1996. Outlet tube No.2 was repaired in 2001. Governor and the station service transformer were replaced in 2002 and 2003 respectively. Generator was shut down during the winter of 2002-2003 due to lack of water. Unit was uprated to 31,500 kilowatts in 2004. Design and repair of penstock gate stem holding system is scheduled for 2003-2004. Lightning arrestors on the 115 KV cable are to be changed, and scheduled for 2003-2004. Remote main breaker racking devices is to be installed in 2003-2004. This plant is used for control of the water flow in the Gunnison River. At least 1 MW is used to control flow variations caused by reservoir level changes.
