Transmission & Distribution

Moving power where it’s needed – our capabilities help provide a safer and more reliable electric grid.

Transmission and distribution overview

In 2015, RES acquired System 3, a specialty HV electrical contractor, and established its self-performing T&D construction division. Our T&D team continues to support our clients with the same quality service of System 3, backed by the in-house engineering, HSQE (Health, Safety, Quality and Environmental) program, and project management experience of RES.

RES T&D has built over:

300 miles

of distribution circuits

Everyone goes home safe every day

Safety is our number one priority, whether on construction sites or in the office. We use behavior-based safety methods to supplement our safety management system and to enhance the safety culture among our work crews and subcontractors. Safety strategies include:

  • Safety walks
  • Tracking leading indicators through behavioral observations
  • Positive recognition
  • Consistent safety messaging
  • Safety guidance
