ATC: Expenditures as of June 30 on Bunker Hill-Blackbrook (M13) Project were about $22.2m

American Transmission Company (ATC), in a July 17 quarterly progress report for the period April 1 through June 30 regarding its Bunker Hill-Blackbrook (M13) Project, told Wisconsin regulators that expenditures as of June 30 were about $22.2m, or about 75% of the authorized total of about $29.7m.

As TransmissionHub reported, the Public Service Commission of Wisconsin 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 July 17 filing, ATC discussed transmission line construction milestones, noting that construction in the rebuild section of the project is complete and that the demolition of the old Line M13 between the Bunker Hill and Blackbrook substation sites is also complete. Restoration work on the right of way (ROW) will continue through the summer, ATC said, noting that the final phase of T-line construction will start in late 2018, with all work scheduled to be complete by next spring.

Regarding substation construction milestones, ATC said that construction of the new Ackley substation and work at all connected remote substations is complete. Site restoration work at the Ackley substation will continue through summer, ATC said, noting that the demolition of the Bunker Hill and Blackbrook substations is complete.

Discussing environmental milestones, ATC said that environmental monitoring began with the start of ROW clearing, and that monitoring continues for the new Ackley substation, as well as on the ROW for the rebuild until restoration is complete.
