Our Energy Group builds projects from the field to the grid. Whether solar, battery storage, substation, EV charging, microgrid or converter station projects, our skilled project managers, engineers and field employees deliver when it matters most. We work with customers on programs of all sizes—whether they span several smaller sites or cover thousands of acres.

Solar PV Solutions

With more than 2 gigawatts (GW) of solar built to date, we at Cupertino Electric have quickly become one of the largest Engineering, Procurement and Construction (EPC) solar companies in California, working with commercial, utility and municipal customers of all shapes and sizes. Our in-house Asset Management Platform (AMP) monitors the utility-scale solar and energy storage projects we design via alerts, controls and Supervisory Control and Data Acquisition (SCADA) integration to maximize performance and minimize operations and maintenance.

Leveraging our EPC utility-scale solar expertise, we offer energy storage solutions for customers to maximize their renewable energy investments. With more than 3 MWh of battery energy storage systems and 2,100 MW of generator capacity installed to date, CEI has a long track-record of success with utility, municipal and corporate customers alike.

Grid Paralleled or Autonomous
Turnkey Microgrids

From design and installation to interconnection and coordination, we've got you covered. Our turnkey microgrid projects combine solar and/or natural gas generation with battery storage and can operate parallel to the existing grid or in a standalone capacity. 

With years of EPC solar experience, combined with generator and battery storage data center project experience, our team can manage behind-the-meter commercial-type connections or before-the-meter IOU interconnections, including Rule 21 coordination.

Substations & Converter Stations

Our skilled linemen combine quality work with a respectful approach and are dedicated to delivering projects safely for employees, the public and the environment. We offer design, pre-construction, construction, program management, maintenance and support services. Our robust in-house team includes civil and electrical engineers, linemen and project management staff who collaborate to resolve issues and deliver projects on time.

We are adept at helping customers meet evolving reliability requirements and upgrading or replacing aging systems. We design solutions for any electrical problem customers face.

In addition to conventional and distributed generation projects, we deliver infrastructure projects like those built for PG&E at mobile home parks across California to meet a California Public Utilities Commission (CPUC) safety mandate. These “programmatic” projects are typically Design/Build and involve electrical and gas upgrades performed simultaneously in multiple locations.

When it comes to infrastructure projects, we believe that our communications efforts with residents are just as important as the work we put into designing, managing and delivering projects safely.
