American Transmission Company (ATC) on Jan. 24 filed with the Public Service Commission of Wisconsin a quarterly progress report for the period Oct. 1, 2017, through Dec. 31, 2017, noting that the Branch River Electric Reliability Project remains on schedule with a projected February in-service date.
As TransmissionHub reported, the commission at a July 2015 open meeting granted ATC a certificate of public convenience and necessity (CPCN) for the project. The PSC voted to approve ATC’s preferred substation site and route alternative for the project.
According to the commission’s final decision, which has a “service date” of Aug. 14, 2015, ATC in October 2014 filed with the commission an application for a CPCN to build the Branch River project. ATC proposed to build a new 345-kV switching station, to be known as the Branch River substation, at one of two adjacent sites in the town of Franklin, Manitowoc County, Wis. A new 345-kV transmission line would be built to connect the new substation to the existing transmission system, the commission added, noting that an existing 138-kV line would also be relocated in order to accommodate the new 345-kV line construction.
ATC said in its application for the Branch River project that the project is needed to strengthen the company’s transmission system and to remove operating restrictions on the Point Beach nuclear generating units in Manitowoc County.
Regarding the substation portion of the project, ATC said in its Jan. 24 progress report that installation of substation equipment foundations, supports, and equipment was completed, and that security cameras were installed. Commissioning work has begun, the company said.
Of the transmission line aspect of the project, ATC noted that installation of structure foundations was completed; structures were also assembled and erected. Conductor and shield wire were strung, the company said.
ATC noted that the “estimate at completion (as of December 31, 2017)” project costs were about $27.7m, and that the “ordered” total gross project cost is about $40.9m.
