Wayne Child Substation

 

 

Tri-State is proposing to build a new electrical substation east of Cheyenne, Wyoming. The new Wayne Child Substation will be located south of the new Archer Development Complex currently being built by Laramie County. This new substation project would provide electrical power to local customers and upgrade the reliability of the existing transmission line system.

 

The new substation would be constructed in two phases, and when complete would occupy 30 acres. Phase I would serve Tri-State's member, High West Energy, in meeting electrical load for the Archer Development Complex in 2012. Phase I involves construction of an access road, 5.5 acre distribution substation, a storm water detention pond and a 230-kV "tie-line" to the existing Archer Substation owned and operated by the Western Area Power Administration.


Henry Lake Substation is of similar design to the proposed Wayne Child substation.

 

Phase II involves connecting Tri-State's existing Laramie River Station to Story 345-kilovolt (kV) transmission line to increase system reliability. Phase II would be constructed in the future, possibly as soon as 2014.

 

Combining High West Energy and Tri-State equipment into one facility increases efficiencies and minimizes the facility footprint and environmental effects. The Project would consolidate and more efficiently serve both Tri-State's need to increase system reliability and High West Energy's need to provide electrical service to Laramie County's new Archer Development Complex.

 

 

 

Tri-State is requesting that the Rural Utilities Service (RUS) provide financial assistance for the proposed project. As a result, the project is subject to the National Environmental Policy Act (NEPA) and requires an Environmental Assessment (EA). The EA includes the project's purpose and need, alternatives, description of the project, affected environment, analyses of potential effects to the natural and human environment, mitigation, and monitoring measures.
