A new transformer was installed recently at the Chandler Substation near Escanaba, Mich., by American Transmission Co., one of several projects underway to improve local reliability. Congestion on the transmission system occurs nearly every day in that area; when maintenance work requires system components to be de-energized, electric service to local customers must be curtailed. The new transformer, along with a proposed new transmission line and substation, will greatly enhance the reliability, operability and performance of the system.
ATC is proposing to build a 6-mi, double-circuit 138-kV line and a new substation. The line would run from the current Chandler Substation to a new substation called 18th Road.
The project is in the public review process with final route selection scheduled for first quarter 2012 with an in-service date of June 2014.
