Safety and Operational Metrics (SOMs)

The California Public Utilities Commission (CPUC) uses Safety and Operational Metrics (SOMs) to enhance regulatory oversight and enforcement of Pacific Gas and Electric Company (PG&E) to ensure they are improving risk mitigation and monitoring safety performance. The SOMs are used to systemically evaluate PG&E’s operational safety performance and to further implement the Enhanced Oversight and Enforcement (EOE) Process imposed upon PG&E by the CPUC as a condition of approving PG&E’s bankruptcy reorganization plan.

SOMs include 32 metrics to monitor PG&E’s electric (wildfire) safety, electric reliability, and natural gas safety. PG&E must file biannual reports with the CPUC that include, for each and every metric, historical data, proposed targets, a narrative description of progress towards proposed targets, and a description of current and future activities to meet the proposed targets.  Engineers and analysts at the CPUC use qualitative and quantitative techniques to assess each metric's current data and historical trends. The EOE process may be triggered if PG&E shows insufficient progress by failing to meet targets contained within the approved SOMs. For more information, please see our Frequently Asked Questions on SOMs.

For the dashboard below, which visualizes the historical performance and proposed targets for each SOM, please select the metric of interest, report submission year, and how many standard deviations (represented by dotted red lines) of each metric history to show (zero standard deviations will simply show the historical average.
