ATC: ROW clearing between Bunker Hill and Blackbrook substations anticipated to be completed by April

American Transmission Company (ATC) on Jan. 17 submitted to Wisconsin regulators a quarterly progress report for the period Oct. 1, 2016 through Dec. 31, 2016, for the company’s Bunker Hill-Blackbrook (M13) Project, noting that engineering design and procurement is in progress.

As TransmissionHub reported, the Public Service Commission (PSC) of Wisconsin last July 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.

In its Jan. 17 filing submitted to the PSC, ATC said that right of way (ROW) clearing has started between the Bunker Hill and Blackbrook substations, and is anticipated to be completed by April.

Substation construction is planned to begin in 3Q17, the company said, adding that environmental monitoring began with the start of FOW clearing.

Expenditures as of Dec. 31, 2016, were about $3.8m, or about 13% of the authorized total of about $29.7m, the company said.
