Physical Security of Electric Infrastructure (R.15-06-009)  

Initiated in June 2015 in response to passage of Senate Bill 699, this proceeding directed the Commission "to consider rules to address the physical security of the distribution systems of electric corporations."


Recent Activities:

During 2017, SED’s risk assessment section facilitated four public workshops and convened a technical working group to provide information on appropriate policy actions for the Commission to consider.

Information from the workshops, as well as staff research, site visits and interviews, have been documented in a new whitepaper released in January 2018 detailing strategies for utility protection of key distribution infrastructure and Commission oversight.

The report is titled, “Security and Resilience for California Electric Distribution Infrastructure: Regulatory and Industry Response to SB 699”. The report assesses the readiness of California’s electric utility companies to respond to a terrorist attack and the grid’s ability to withstand an organized attack, and makes recommendations for low-cost practical solutions that would further enhance grid security and reduce the risk of a terrorist attack.

Rather than focusing solely on “hardening” the physical security of facilities, the report recommends that all electric utilities operating in California boost resiliency — a facility’s ability to withstand an attack and the grid’s ability to withstand potential loss of a substation.

Separately, the Commission in R.15-06-009 is considering a Joint Utility Proposal for Distribution Substation and Distribution Control Center Security Programs and Mitigation Plans.  Here is the report and SED's recommendations for consideration.
