Los Alamos Department of Public Utilities officials reported a power outage affecting about 120 customers in North Mesa’s Tsikimu Village neighborhood beginning at 10:50 a.m. Wednesday. Power was restored to all but six customers at 11:30 a.m. and to the remaining six at 12:10 p.m., the DPU said.
Trenching work on the Sioux Street Underground Electric Cable Replacement Project caused the line failure which affected a transformer. The permanent repair work included the replacement of the affected transformer. Sioux Street’s underground electric system has failed numerous times in the past as much of the infrastructure is at or beyond its manufacturer-specified lifespan. The existing system, which was originally installed as direct bury cable, has been prioritized for replacement now because of its age and recent failures.
“The Sioux Street Underground Electric Cable Replacement Project encompasses the replacement of approximately 3,800’ of electric conductor line and the installation of conduit and multiple circuits for redundancy, to improve electric reliability in the neighborhood,” Project Manager Stephen Marez said. “At project completion, scheduled for March 2014, the enhanced redundancy will improve performance and help curtail time to restore power should a future power outage occur.”
The project is part of the DPU’s Electric Reliability Plan initiatives. For more information visit, http://bit.ly/KWrEKQ.
