Reporting Serious Electrical Incidents

On October 1, 2017, new serious incident reporting requirements come into effect as a result of amendments made to Electrical Distribution Safety Regulation 22/04.

ESA intends to use the existing reporting processes for the expanded definition of serious electrical incidents under O.Reg 22/04. ESA will update the Guideline for Serious Electrical Incident Reporting and the Serious Electrical Incident Report Form to include meters. These will be available in mid/late September, and ESA will work closely with each LDC to support them in meeting their compliance.

The key changes are:

  • Mandatory reporting requirements for Local Distribution Companies (LDCs) to include all serious electrical safety incidents involving meters except in cases of events of force majeure;
  • The definition of “worker” in the regulation has been amended to align with the Occupational Health and Safety Act;
  • A definition for force majeure has been added;
  • A requirement for LDCs to assist ESA in investigations of serious electrical incidents of LDC-owned assets; and
  • Updated references to existing National Standards that LDCs are currently following.


Section 12 of the Regulation requires that a distributor notify ESA of any serious electrical incident within 48 hours. The Guideline for Reporting Serious Electrical Incidents clarifies what should be reported and how it should be reported; it also includes a template for reporting information to ESA.
