Expenditures as of Dec. 31, 2017 for Bunker Hill-Blackbrook project were about $16.3m, company says

American Transmission Company (ATC), in a Jan. 24 quarterly progress report for the period Oct. 1, 2017, through Dec. 31, 2017, filed with the Public Service Commission of Wisconsin, said that construction in the rebuild section between the Bunker Hill and Blackbrook substations is ongoing and expected to be completed in the spring.

“All T-line construction is scheduled to be completed by the fall of 2019,” the company said in reference to the Bunker Hill-Blackbrook (M13) Project.

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 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.

In its Jan. 24 filing, ATC said that substation construction at the new Ackley substation is in progress and expected to be completed in the spring.

Environmental monitoring began with the start of right of way (ROW) clearing, ATC said, adding that monitoring is continuing for the new Ackley substation and on the ROW for the rebuild.

Expenditures as of Dec. 31, 2017, were about $16.3m, or about 55%, of the authorized total of about $29.7m, the company said.
