Cherokee to Federal Heights to Semper to Broomfield Transmission Project

Home > Cherokee to Federal Heights to Semper to Broomfield Transmission Project

Overview

We are installing upgraded 115 kV transmission line circuits that connect the Cherokee, Federal Heights, Semper and Broomfield substations in the north Denver metro area. The upgraded line will follow the existing transmission corridor, and construction will occur in two segments. These upgrades will increase system reliability and accommodate future distribution services.

Rebuilt electric transmission line:

  • Cherokee substation to Federal Heights substation.
  • Federal Heights substation to Semper substation.
  • Semper substation to Broomfield substation.

This project is part of the larger Denver Metro Transmission Upgrades to upgrade the existing electric system to support new power generation sources and meet future electricity needs.
