Guam – A major capital improvement project to upgrade the Tumon Substation has reached its halfway mark. Motorists Northbound along Route 1 in Upper Tumon can view the project across John F. Kennedy High School. 

A new transformer with more capacity is being installed. Improvements include a greater ability to backfeed (reroute power) and support other distribution lines to improve system reliability and redundancy along with a new transformer containment pad to comply with environmental protection regulations.

“This project is part of a $43M upgrade for the Island Wide Power System to improve power quality and reliability,” stated Irwin Loyola, Engineering Supervisor, “The funds are part of GPA Revenue Bonds issued in 2010 for major capital improvement projects (CIPs) to upgrade aging equipment.”
