Electric Safety and Reliability

The Electric Safety and Reliability Branch (ESRB) enforces CPUC rules and regulations to ensure that power plants and utility companies run a safe and reliable electric or communication system.  ESRB regularly conducts audits and inspections, investigates safety incident or system problem, and advises the CPUC on related matters.  ESRB consists of two sections: Electric Generation Safety and Reliability Section (EGSRS) which oversees generating asset owners and power plants, and Electric and Communication Facility Safety Section (ECFSS) which oversees electric and communication utility companies.  Click on the links below to find out more about the work of these sections.

Important Safety Information

Touching or being in close proximity to overhead or underground electric facilities could lead to serious injury or fatality.  The equipment may contain high energy that could pose a serious safety hazard.  Please follow these safety tips:

  • If you see a down power line, always assume it is energized.  Do not touch it and stay away from the area.  Call 911 or the local fire department to report the downed line. 
  • If you see a power line that is very close or in contact with any part of a tree, do not attempt to clear the tree-line contact yourself.  Stay away from the tree and call the electric utility to report the tree-line contact. 
  • If you plan to dig on your property, call Underground Service Alert (USA) to locate all underground facilities in the excavation area, including power and gas lines.  Dial 811 at least two day before the excavation starts.  More…
