Utility Risk Assessment and Safety Advisory

The mission of the Risk Assessment and Safety Advisory (RASA) section is to promote safety by ensuring that the regulated entities integrate risk analysis and risk management practices into their current operations, future planning, and decision-making processes. The section's professional engineers and analysts apply technical and regulatory policy expertise to a wide variety of Commission proceedings and initiatives in order to:
  • Identify, analyze, and mitigate present and potential risks in the natural gas & electric systems;
  • Promote risk-informed decision-making in Commission proceedings, particularly General Rate Cases;
  • Suggest improvements in audits and inspections performed by SED;
  • Coordinate with other Commission divisions, State and/or Federal agencies to promote safety in regulated utility operations and research expenditures;
  • Identify and promote new approaches to Risk Assessment and energy policy development through whitepapers, reports and presentations at industry conferences.


The Risk Assessment section is specifically tasked with monitoring proceedings and rate case testimony to ensure that relevant Safety concerns are adequately considered:

  • Identify safety concerns and issues that should be considered in new applications, rulemakings or investigations and provide recommendations to Commission decision-makers;
  • Refer to appropriate agencies with overlapping or parallel jurisdiction any Safety concerns that arise in proceedings;
  • Monitor compliance with Commission decisions and Ordering Paragraphs that provide specific directions to SED.


Accomplishments in 2017; Goals for 2018

During the past year, the Risk Assessment & Safety Advisory section was able to meet several critical milestones, including finalization of staff evaluation reports for Southern California Edison's General Rate Case and the Sempra Utilities' Risk Assessment Mitigation Phase (RAMP) proceeding, along with completion of a consultant's report in the Pacific Gas & Electric Safety Culture investigation, and staff reports on Physical Security of Electric Infrastructure and a Joint Report with CARB staff for the 2016 Natural Gas Leak Survey.
RASA staff has earned a reputation for high quality, timely work products, participatory workshops and technical group facilitation that all contribute to Commission decision making for some of the CPUC's highest profile, complex proceedings.
For 2018, RASA's priority will be to help bring several ongoing proceedings to a successful conclusion, so that the safety-related policies being developed can be fully implemented and incorporated into utility practices.


Major Proceedings

Safety Model Assessment Proceeding (A.15-05-002, et al) After nearly a full year in which utilities and intervenors refined proposed methodologies for identifying, ranking and developing mitigations for top operational and safety risks, this S-MAP proceeding is targeted for completion during 2018.  In 2018, staff will be evaluating the utilities' risk assessment models for future use in RAMP and GRC cases, while finalizing policies for accountability reporting, safety performance metrics, and applying risk-informed ratemaking to smaller energy utilities.

Physical Security of the Electric Supply System (R.15-06-009)  With the publication of a RASA staff whitepaper that maps California’s response to new threats to the electric grid, and assesses existing conditions, the CPUC has responded to directives of SB 699 and PU Code 364 to ensure the safety and security of those electric grid assets subject to Commission oversight. Also, in response to a Joint Utility Proposal that seeks to outline new criteria and requirements for identifying “critical” assets and developing threat assessment and mitigation plans, RASA staff has put forward a set of recommendations for additional provisions to the Joint Proposal. A Proposed Decision from the Commission is expected to be made available in the 3rd Quarter of 2018.

Water and Electric Utilities Disaster Preparedness and Emergency Response – Coordination with Local Governments (R.15-06-009, Phase 2)  A second phase of the R.15-06-009 rulemaking that responds to AB 1650, and Section 768.6 to the Public Utilities Code is in progress. These directives require, among other things, that water and electric utilities develop disaster and emergency preparedness plans, and seek local government input so as to improve communication with the public, and mitigate the effects of catastrophic events. A scoping memo outlining the priorities to be addressed and prescribing a series of public workshops has been made available.

 Other Proceedings

General Rates Cases During 2018 Throughout the year, RASA has worked closely with utilities and intervenors to develop  the framework and substance for new aspects of the Rate Case Plan that are being developed in the S-MAP proceeding (see above) to incorporate a risk-informed approach to General Rate Cases.   Each GRC exhibits a deeper and more refined set of expectations for utilities to show how they are identifying, prioritizing and addressing safety and operational risks.  This effort is unique in utility regulation nationally, and the RASA provides expert analysis and assistance to bring about successful collaboration to resolve what could be highly contentious issues and proceedings.

  • In order to help close out two major proceedings (PG&E 2014 GRC and Risk-Informed Ratemaking OIR) RASA staff analyzed over 50 consultants’ report recommendations to determine whether they were being addressed in related proceedings or if further action was required. In November, 2015, this analysis was incorporated into an Assigned Commissioner’s ruling in R.13-11-006 deferring residual matters into proceedings listed above (esp. PG&E 2017 GRC, SMAP and Leak Abatement).
