When Healdsburg needed to modernize its 69-kV substation, it required an electrical contractor with technical expertise in medium voltage utility distribution and substations. It also needed a company with a proven safety track-record. So, it selected Cupertino Electric (CEI).
In addition to ensuring safety at the jobsite, CEI’s project team had to work fast. During the limited period of time when power was turned off to the city’s residents and businesses, CEI installed additional circuit switchers, refurbished two 25 MVA 69kV to 12.47 kV transformers and reconfigured the bus. Cupertino Electric successfully completed its work without incident and minimized the required scheduled outage.
