PurposeGeneration of hydroelectric power for use in the project.
FactsThe 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.
HistoryTransformer 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.
Present ActivitiesDesign 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.
Special IssuesThis 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.
