Incident Investigations for Electric and Communication Facilities

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

  • A fatality or injury involving electric facilities.
  • Damage to property of the utility or others in excess of $50,000.
  • Significant media coverage.
  • A major outage to at least 10% of the utilities entire service territory is experienced at a single point in time.

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.
