American Transmission Company (ATC) recently submitted to the Public Service Commission of Wisconsin its quarterly progress report – for the period April 1 through June 30 – for its Branch River Electric Reliability Project.
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 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 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.
In its June 30 progress report, which has a “received date” of July 20 on the PSC’s website, ATC said that the project remains on schedule, with a projected February 2018 in-service date.
Planned 3Q18 activities include completion of substation foundation installation; installing the substation control building; continuing on balance of substation construction; starting vegetation management for the transmission line; and installing transmission line structure foundations, the company said.
Under “project status,” ATC said that detail design activities continued; vegetation management activities at the substation site were completed; substation site grading and preparation, as well as fence installation were completed; and substation foundation installation as well as other below grade work, and installation of equipment supports began.
Actual project costs through June 30 were about $16.3m out of the total gross project cost of about $40.9m, the company said.
