Battery Energy Storage Systems Classification Studies
CSLB has studied battery energy storage systems (BESS) since October 2016, after receiving public inquiries about the proper contractor license classification to install BESS. Staff held multiple public meetings, listening to hours of public testimony from hundreds of stakeholders, and has solicited and reviewed thousands of pages of technical BESS information.
June 30, 2021 UC Berkeley Battery Energy Storage Systems License Classification ReportOn December 19, 2019, the Board determined that an outside consultant would be helpful in reviewing all the BESS information received, and/or any need for possible additional information, and produce an independent analysis regarding the appropriate license classification to install BESS. In December 2020, CSLB contracted with the University of California, Berkeley to evaluate this issue.
