Presque Isle to Rest Lake 34.5 kV Project

Project Need

Xcel Energy is proposing to rebuild two substations in Vilas County to increase reliability for the region. The Presque Isle Substation and Rest Lake Substation were originally built in the mid -1900s. We are proposing to rebuild the substations and adding a new 34.5 kilovolt transmission line connecting them to improve system reliability.

The existing Presque Isle Substation is served by an 11.4 mile 34.5 kv transmission line from the Mine Road Substation near Bessemerg, Mich. (see map); the existing Rest Lake Substation is served by a 13.6 mile 34.5 kV transmission line from Weber Lake Substation near Mercer, Wis. Both transmission lines are ‘radial’ lines, meaning they can only deliver electricity in one direction, and are unable to back-feed power if one of the transmission lines is out of service due to storms in the area or other outage situations. These lines have had numerous outages over time and rebuilding this infrastructure will improve service in the area by enabling the system to transfer power from either direction, preventing outages from occurring.

The existing Presque Isle Substation is located between Hwy B and a steep slope with not adequate room to build a new substation.  The existing Rest Lake Substation is located on State of Wisconsin property without adequate land rights to build a new substation.  Because of the land constraints with the existing substations we are seeking new locations for both substations with the plan to remove the existing substations once the new ones are in service.  When the substation locations are identified we will work with local officials and landowners to determine the best route for the new transmission line.
