Midwest Transmission Project

Transource Energy’s Midwest Transmission project is a 135-mile, 345 kV line originating in Sibley and terminating at a substation in Nebraska City. Previously, the project was regarded as the Sibley to Nebraska City project. The project was energized on December 19, 2016. This project was originally identified by the SPP as a Priority Project to improve reliability, reduce congestion and improve the east to west transfer capability in the area. All of the Priority Projects combined are expected to bring $3.7 billion in savings over a 40 year window. Watts Electric Company of Waverly, Nebraska was contracted to perform substation work for the project, while Timberline Construction, Inc was awarded the contract for transmission work.
