ATC files application for transmission line project in Brillion

New substation, short segments of new wire planned

DE PERE, Wis. – American Transmission Co. today filed an application with the Public Service Commission of Wisconsin to build a new substation and transmission line on Brillion Iron Works property. The project also involves extending the current double-circuit transmission line about one-quarter mile to connect to the new substation. Additionally, one mile of fiber optic wire will be installed from the Glenview Avenue Substation near the Brillion water tower to the new substation.

“Brillion Iron Works is served by a radial distribution-level substation owned by Wisconsin Public Service Corp.,” said Lee Meyerhofer, ATC senior local relations representative. “The large industrial load at the facility now warrants a networked transmission-level facility, which is the most economical solution to improve reliability for the customer.”

The new substation will replace the aging Brillion Iron Works Substation, which will be retired when the new substation is placed in service.

If approved, construction would begin in summer 2015 and the project would be placed in service in summer 2016. The estimated cost is $14 million.
