About
Ranked #1 in solar and storage in the U.S. and operating across 33+ states with more than 5,300 employees, Cupertino Electric Inc. (CEI) is one of the most capable commercial electrical contractors serving San Jose and the broader California market. Founded in 1954 and now a Quanta Services company, CEI brings over 70 years of experience delivering high-complexity electrical infrastructure for energy, data center, and commercial clients. Facility managers and property owners dealing with large-scale or technically demanding projects will find CEI's integrated approach — combining in-house electrical engineering, expert project management, and skilled union field crews — particularly well suited to mission-critical and phased construction work. CEI's commercial portfolio spans power distribution, switchgear installations, panelboard upgrades, lighting systems, and low-voltage/data infrastructure across healthcare campuses, office complexes, institutional facilities, mixed-use developments, and large industrial sites. Demonstrated project examples include full electrical infrastructure and lighting systems for the Sutter Health Innovation Center in San Francisco and electrical, controls, and infrastructure upgrades at the Rinconada Water Treatment Plant in Los Gatos — both illustrating CEI's capability on sensitive, highly regulated facility types. The firm holds California contractor licenses across General Engineering (A), General Building (B), C-10 Electrical, C-46 Solar Power, and C-7 Low Voltage, making them a single-source partner for complex multi-trade electrical scopes. For facility and property managers overseeing large commercial buildings, healthcare facilities, public infrastructure, or multi-site portfolios in the San Jose metro and beyond, CEI offers the engineering depth and geographic reach to execute projects at scale while maintaining rigorous safety and quality standards.
