Electric Mutual Aid Safety Onboarding

Electric mutual aid contractors and/or outside utilities will find work rules, training materials and applicable documents here to help you complete your job safely.


  • Each non-Eversource crew member (contractor and outside utility) is required to be on-boarded prior to the start of restoration work.
  • The General Foreman or Foreman/Lead assigned to crews for the contractor and/or outside utility will be responsible for taking applicable safety onboarding and disseminating the information to their assigned crews.
  • Existing contractor crew leads already on Eversource property prior to a storm event (for example, Contractors of Choice (COC)), require a formal on-boarding that is valid for one (1) year.
  • COC’s are considered to be contractors that support blue-sky, day-to-day work, with Eversource. If contractors are brought in from outside CT/MA/NH and are under a COC name, they will still be required to onboard and be considered a non-COC.
  • Formal on-boarding for a non-COC, as well as Foremen/Leads from a COC company but traveling from an area outside our service territory (CT/MA/NH), are valid for six (6) months.
  • Aggregator companies (i.e. Parent companies that hire sub-subcontractors to work under the Parent Name), shall ensure that the Foreman/Leads from the hired companies complete the onboarding and acknowledgement form. Eversource requires that the name on a company truck matches with the name given on the acknowledgement form.
  • Safety questions or concerns can be sent directly to
