City of Healdsburg Substation Modernization
Cupertino Electric utility construction project for the city of Healdsburg, California
69 kV substation, 50 MVA
Surrounded by several of Northern California’s best regional wineries, the city of Healdsburg is a favorite destination of tourists and home to more than 11,500 full-time residents. When Healdsburg needed to modernize its 69 kV substation, it required an electrical contractor with specific technical expertise in medium voltage utility distribution and substations and a proven track-record of safety.
In addition to ensuring safety at the jobsite, Cupertino Electric's project team had the challenge of installing additional circuit switchers, refurbishing two 25 MVA 69 kV to 12.47 kV transformers and reconfiguring the bus during a limited period of time when the power to the city’s residents and businesses was turned off. Cupertino Electric successfully completed its work without incident, while minimizing the required scheduled outage.
