Energy Storage Systems

In April 2018, the Board directed CSLB staff to conduct public meetings and collect information regarding the appropriate license classification(s) authorized to contract for and install an Energy Storage System (ESS).

At its March 2019 quarterly meeting, the Board unanimously adopted the following motion after reviewing staff’s ESS Report (linked below), considering related correspondence, and receiving testimony from 74 members of the public:

  1. Consider battery energy storage system size, complexity, voltage, and potential risk.
  2. Draft a proposed regulatory package for board consideration that would prohibit or restrict certain contractor classifications from performing the installation of battery energy storage systems.
  3. Assign this to the appropriate board committee or committees and provide updates at each board meeting.

The Board Chair assigned the review to the Legislative Committee. Concepts for regulatory proposals related to battery ESS installation will be presented for the committee’s review at its August 6, 2019 meeting. That meeting will be held in the Employment Development Department Auditorium, 722 Capitol Mall, Sacramento, CA 95814. The agenda will be posted on this website at least ten days prior to the meeting date.
