NES to activate new substation; old facility will be demolished to make way for MCC

Crews will undertake Tuesday a second transfer of electric power as part of the final process to activate the new Nashville Electric Service substation at Sixth Avenue South, Peabody Street and Korean Veterans Boulevard and deactivate the long-used facility at Sixth and Demonbreun Street.

Tim Hill, NES spokesman, said C&M Network crews worked throughout the past weekend to transfer power on what is called the East Network from the Demonbreun substation to the newly constructed Peabody substation. The East Network provides slightly less than half of all the power served out of the Demonbreun substation.

The transfer was not noticeable to customers, Hill said, and there were no outages needed. Crews were required to splice new power cable into existing power lines and then remove some of the old power cable coming from the Demonbreun substation, he added.

After Tuesday’s effort, “all load will be served out of Peabody substation and our crews will then begin the process of decommissioning Demonbreun substation,” Hill said.

With the Demonbreun substation no longer operable, its demolition will take place soon as the facility is within the footprint of the rising Music City Center convention facility.

The project remained on schedule and recently saw, among other elements, the installation of a gas insulated switchgear (GIS) system manufactured by South Korea-based Hyundai.

The Peabody substation is enclosed but the structure’s exterior skin won’t be added until near the completion of both KVB extension and MCC in early 2013.
