Electric utilities must report electric incidents (accidents involving electric facilities), which meet any of the criteria below:

  • Result in fatality or personal injury that requires medical attention from a healthcare professional at a hospital or other medical facility and are attributable or allegedly attributable to utility-owned facilities; or
  • Are the subject of media coverage and are attributable or allegedly attributable to the utility electrical facilities (media as used in this context refers to any of the major news outlets and publications (i.e. a minimum daily circulation of 25,000 or minimum daily followers of 25,000) in the area, city and/or county where the incident occurred); or
  • Involve damage (caused by a utility facility) to property estimated to equal or exceed $200,000. Property in this section refers to any utility-owned and/or non-utility owned property and facilities. In calculating the amount of damages, the utility shall estimate the cost to replace any damaged facilities that belong to the utility or properties of a non-utility entity. The cost does not include the labor involved to replace the damaged facilities and should be broken down to show the cost of damages to the utility’s facilities and non-utility properties; or
  • Prompted a government entity to investigate whether the infrastructure owned or operated by the utility caused a wildfire.

In general, the electric utility must report these types of incidents to the CPUC within two (2) hours of their occurrence. ESRB investigates these incidents to enforce the CPUC’s rules and regulations and to determine how we can limit the occurrences of such incidents in the future. ESRB produces an investigative report for each incident reported and investigated.

To request a copy of a report, please contact our Legal Division with a specific and focused request so that the records can be identified, located and retrieved by our staff:
