  • “Having reliable communications available at every point on the system increases the reliability of the electric system. Highspeed communications with substations, reclosers, and circuit breakers will allow for data transfer that will help predict outages; the location of a potential fault can be determined and corrections made before an outage occurs. When outages do occur, promptly locating the cause and restoring power is made easier thanks to this highspeed fiber network.”
