Williston Area Transmission Line Upgrades

Duke Energy is committed to providing customers with reliable, safe and increasingly clean energy. We’re improving our transmission infrastructure, the backbone of our state’s energy system – powering communities and helping to build the smarter, cleaner energy future that customers want. Two existing transmission lines to the west and north of the existing Williston Substation are being upgraded to support the new Williston Bronson line and to maximize reliability and grid performance. The improvements to these lines will begin in 2023 and continue into 2024.

Williston Bronson Transmission line route options

Martin West to Williston North

New wires are being installed on existing structures to add capacity to enhance the ability of Duke Energy and other utilities in the area to provide more reliable energy and also help reduce the risk of power outages. The project also involves the installation of new poles at the mid-point between the existing structures to support the new line. Construction will be completed during the third quarter of 2024 followed by several months of restoration.

Archer to Williston

New transmission structures were installed in the 3-mile corridor in 2020 to accommodate a second 230-kV transmission line. Remaining work on the north end and south end on of the line will be completed the first quarter of 2024 followed by restoration activities.

The projects described above are needed to support the Williston to Bronson New Transmission Line and Substation Project.
