American Transmission Company (ATC) on April 24 told the Public Service Commission of Wisconsin that the Branch River Electric Reliability Project was placed in service on Feb. 28.
Restoration and minor site work is in progress, the company added in its quarterly progress report for the period Jan. 1 through March 31.
Actual project costs through March 31 were about $27m, out of the “ordered” approximately $40.9m, the company said.
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 commission 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.
