The new transmission line will extend approximately 17 miles from a new Williston North Substation being constructed at 4991 NE Highway 41, directly north of the existing Williston Substation. The new transmission line will extend to the existing Bronson Substation located at 790 N. Hathaway Ave. in the town of Bronson.

Both the existing Williston and Bronson substations are also being upgraded and expanded. Substation work at the sites began in late summer 2021.

In addition to the new transmission line and substation, existing transmission lines to the east and north of Williston Substation are being upgraded to maximize reliability and grid performance. The improvements to these lines will occur late 2021 and into 2022.
