Greeley Substation Upgrades

Location

Greeley, CO

Project Description

In order to support system upgrades, a rebuild of a large existing substation, which included three transmission lines, two distribution banks, two transformers, one 44kV transmission line, and two 115kV capacitor banks was necessary.

Outcome

As the lead engineering consultant, PRE designed and supported the rebuild. In addition, the existing substation was a straight bus design where it was difficult to take any equipment out of service. As a solution, the new substation was built adjacent to the old substation, converting the sub to a breaker and a half design, and the loads and lines were swung over to the new yard. Extensive consultation with city officials and substation neighbors was required, which PRE supported.
