Pilot Butte Power Plant was built to supply power to the project. Pilot Butte Power Plant is operated on a seasonal basis during the diversion of irrigation flows to Pilot Butte Reservoir. The Pilot Butte Power Plant, located at the drop from the Wyoming Canal to Pilot Butte Reservoir was taken out of service in June 1973. A new penstock was installed and units were placed in service in June 1990. Emergency repairs were completed in FY 2003 on the stator core of Unit 2. This required disassembly of the unit and removal of the rotor. Repairs to the rotor were also accomplished during the outage. The plant has two generating units which operate under a maximum head of 105 feet with a total capacity of 1,600 kilowatts. Power is distributed over 76 miles of transmission lines.
