American Transmission Company (ATC) on April 22 told the Public Service Commission of Wisconsin that the Riverside Project was energized on March 28 and placed into service on April 11.
As TransmissionHub reported, ATC on April 4 said that work on the 4.2-mile, estimated $42m, 345-kV line included building a new substation near the Alliant Energy West Riverside Energy Center and connecting a new double-circuit transmission line to an existing 345-kV transmission line in the Town of Beloit, Wis.
The line is needed to connect the expanded West Riverside Energy Center – which will include a natural gas-fueled generating station with an integrated solar installation – to the electric transmission grid, ATC said. According to the transmission project’s webpage, the West Riverside Energy Center is expected to begin operation in 2020.
In its April 22 quarterly progress report for the period Jan. 1 through March 31, ATC discussed the transmission line section of the project, noting that structure erection and stringing activities were completed. ATC also said that restoration activities along the transmission line right of way have begun and will continue through early summer.
Of the substation portion of the project, ATC said that commissioning activities of the Kittyhawk and remote end substations were conducted. The company also noted that the generator tie-lines were connected into the Kittyhawk substation and all work was completed by April 2.
Discussing the total gross project cost, ATC said that actual expenditures as of March 31 were about $35.2m, compared to the commission-authorized estimated project cost of about $42.1m.
