Columbia-Rio transmission line completed under budget and ahead of schedule

MADISON, Wis. – American Transmission Co. placed in service last week a new 69-kilovolt electric transmission line connecting the Columbia Substation, located in the Town of Pacific, with the Rio Substation, located in the Village of Rio. The new line will also connect to a new Alliant Energy substation – the Wyocena Substation, in the Village of Wyocena..

Construction began last spring on the transmission line, which runs from the Columbia Substation along State Hwy. 16 into the Wyocena Substation. Construction was completed last month, ahead of schedule.

The 10-mile transmission line helps meet local electricity needs and backs up other critical facilities on the electric system. “This new transmission line will help accommodate the increase in electricity usage due to population growth,” said John Garvin, ATC local relations representative. “Completion of this line gives us a solution to past network challenges.”
