The California Public Utilities Commission (CPUC) conducts ongoing oversight of the state’s energy infrastructure to ensure safety and reliability for residents. The agency’s work includes both regularly scheduled inspections and staff investigations following specific incidents.
CPUC staff carry out planned inspections of various components of the energy system, such as power plants, energy storage systems, electric transmission lines, substations, distribution lines, and natural gas pipelines. These inspections are intended to identify potential safety issues, confirm compliance with regulations, and prevent incidents before they occur.
In addition to routine checks, the CPUC also conducts staff investigations when outages or safety events meet certain reporting requirements. Staff may also initiate investigations if circumstances suggest further review is necessary. According to the CPUC, “The purpose of a staff investigation is to understand what happened, determine whether safety rules were followed, and identify steps needed to reduce the risk of similar events in the future.”
During these investigations, staff collect data and records, conduct site visits or field inspections, interview utility personnel and other relevant parties, and evaluate whether any laws or safety standards have been violated. If immediate action is required due to an identified issue, it is addressed right away; other issues must be resolved by a set deadline with follow-up verification from the CPUC.
CPUC staff have authority to issue citations for certain violations found during inspections or investigations. In more serious cases where significant concerns arise, staff may recommend that Commissioners vote on opening a formal investigation that could result in penalties against utilities.
“Through inspections, investigations, and enforcement, the CPUC works to hold utilities accountable and support the safe, reliable delivery of energy throughout California,” states the agency.
