URGE THE CONTRACTORS
STATE LICENSE BOARD
Protect Public Safety:

Require Qualified Installation of Battery
Energy Storage Systems
Require Only Licensed C-10 Electrical Contractors to Install Battery Energy Storage Systems.

Safe installation of battery energy storage systems by qualified electrical contractors and
electricians is key to protecting public safety.

Battery energy storage systems are rapidly expanding and being installed in schools, hospitals, businesses and homes throughout the state. Battery storage is a key technology to help California meet our clean energy and emissions reduction goals and expand the adoption of solar, wind, and other clean energy sources.

If not installed correctly by highly-qualified and licensed electrical contractors, battery energy storage systems pose unique fire, electrical, and public safety risks to installers, consumers, utility workers, and emergency personnel.

The CSLB should clarify regulations and require the expertise of a C-10 electrical contractors’
licensee to safely install and maintain battery energy storage systems.

“…it would be a mistake for the Contractors State License Board to allow specialty solar contractors that are not authorized to install stand-alone energy storage systems to install these systems…Only contractors who have been trained in electrical risk assessment and electrical theory should work on these potentially dangerous systems."

California regulation specifically prohibits C-46 licensed contractors (solar photovoltaic companies) and their employees from installing battery energy storage systems as a stand-alone project.

The employees of C-46 licensed contractors, have no state requirements for training and certification. As such, they do not receive the extensive and specialized training needed to safely install and maintain battery energy storage systems.

State law requires C-10 contractors to hire licensed electricians who have 8,000 hours of hands-on experience and have passed a rigorous state exam.

C-10 licensed contractors and their certified electrician employees have expertise in all types of electrical work.

C-10 licensed contractors hold a thorough understanding of the National Electrical Code (NEC), which is critical to preventing injury, destruction and death.
