Bunker Hill-Blackbrook (M13) Project placed into service, ATC says

American Transmission Company (ATC) on April 24 told the Public Service Commission of Wisconsin that the Bunker Hill-Blackbrook (M13) Project was placed into service on Feb. 25.

As TransmissionHub reported, the commission in July 2016 granted, subject to conditions, ATC’s application to build and place in service facilities for the project, which includes building a new substation; rebuilding the 115-kV M13 transmission line from the Bunker Hill switching station in Lincoln County, Wis., to the Blackbrook switching station in Langlade County, Wis.; uprating the 115-kV M13 transmission line from the Kelly substation in Marathon County, Wis., to the Blackbrook switching station; as well as retiring and removing the Bunker Hill and Blackbrook substations.

The route of the rebuild portion of the project begins at the Blackbrook substation in the town of Ackley, Langlade County, and follows the existing M13 line route west to the proposed Ackley substation in the town of Pine River, Lincoln County. The rebuild would take place adjacent to the existing M13 line and is 8.2 miles long, the commission added, noting that the route of the uprate follows the existing M13 route south from the proposed Ackley substation to the Kelly substation in the village of Weston, Marathon County.

In its April 24 quarterly progress report for the period Jan. 1 through March 31, ATC said that restoration activities along the right of way were initiated and will continue throughout the growing season.

The actual project costs through March 31 were about $24.8m, ATC said, noting that the commission-authorized total gross project cost is about $29.7m, and that the revised project cost estimate as of Dec. 31, 2018, is about $24.9m.
