The Canyon Power 69-kV gas-insulated switchgear (GIS) switchyard, a major turnkey GIS project provided by ABB, is now providing unprecedented levels of local electricity for the city of Anaheim, California, U.S.
This GIS switchyard interconnects the new 200-MW natural gas-powered Canyon Power Project in Southern California to the city of Anaheim's electrical system. The project now provides up to 150,000 residential customers with additional local electricity to meet Anaheim's peak demands, particularly during its hot summer months. The switchyard will also upgrade local electric system reliability, reduce Anaheim's reliance on out-of-state power resources and enhance the city's ability to provide cleaner energy to its customers.
The Southern California Public Power Authority provided financing, the city of Anaheim provided project management and ABB provided the project on a turnkey basis, including all engineering, equipment and construction labor to design, build, test and commission the switchyard.
The city of Anaheim specified GIS on this project because of the small space available for the switchyard, together with the higher reliability and lower operating and maintenance costs associated with GIS equipment. This GIS switchyard is completely enclosed, because of the low incremental cost of doing so and the ability to make it completely immune to local environmental conditions.
