Initiated in June 2015 in response to passage of Senate Bill 699, proceeding R.15-06-009, now concluded and closed, directed the Commission "to consider rules to address the physical security of the distribution systems of electric corporations."

Utility Annual Reports Submitted to the Commission in Accordance with Requirements of Public Utilities Code Section 590 (click here).


Rulemaking Milestones:

January 22, 2019 - By a 4-0 vote, the Commission on January 22, 2019, approved the Physical Security Decision, D.19-01-018, marking California as the first state in the nation to adopt rules to safeguard its electric distribution grid against terrorist attack. In response, California’s electric utilities have prepared threat assessments and security plans that identify “critical” assets and propose security mitigation measures. Adoption of D.19-01-018 marks another milestone in the CPUC’s Safety Policy Division carrying out the Legislature’s directives of SB 699 and Public Utilities Code Section 364 to ensure the security and resilience of those electric distribution grid assets subject to Commission oversight.

In January 2018, SPD’s Risk Assessment section published a staff white paper 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 such an organized attack,and makes recommendations for low-cost mitigations and approaches to enhance grid security and reduce the prospects and damage of any such future incident. The white paper also provides extensive background on California and Federal steps to establish physical security protocols for the electricity sector,and describes Commission staff's approach to the problem.

In 2017, in support of the proceeding, SPD's Risk Assessment section facilitated four public workshops and convened a technical working group to advance understanding of the issues surrounding physical security, elicit input and expertise from experts and stakeholders, and to reach broad consensus on a set of challenges and opportunities.

In 2015, SB 697 amended Public Utilities Code Section 364 and added Public Utilities Code Section 590, which had the effect of relocating within the Public Utilities Code the language prescribing utility annual reporting requirements.

In 2014, SB 699 amended Public Utilities Code Section 364 to clarify the Commission's broad authority over physical security standards for the California electric distribution grid.
