Planning for right of way (ROW) clearing for the transmission line portion of the Bunker Hill-Blackbrook (M13) Project is in progress and targeted to begin in 4Q16, American Transmission Company (ATC) said on Oct. 24.
Engineering design and easement acquisition for the line are also in progress, the company told the Public Service Commission (PSC) of Wisconsin in a quarterly progress report for the period July 25 through Sept. 30.
As TransmissionHub reported, the PSC on July 25 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 PSC 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.
The proposed project’s estimated cost in 2019 dollars is about $29.7m, and of that, about $21.3m would be for transmission line work, about $7.5m for substation work, and $981,000 for pre-certification costs, the PSC said.
ATC said in its Oct. 24 progress report that engineering design for the substation is in progress, and that substation construction is planned to begin in 3Q17.
A Wisconsin Department of Natural Resources utility permit was received on Oct. 13, the company said.
Expenditures as of Sept. 30 were about $2.8m, or about 9%, of the authorized total of about $29.7m, ATC said.
