NSTAR Deploying Self-Healing Technology

To improve power reliability for consumers, Massachusetts-based NSTAR Electric is deploying General Electric’s so called “self-healing” grid project throughout its service territory. GE’s smart grid technology automatically identifies the location of power outages, isolates faulted sections of the network, and then re-routes power from other sources. Thanks to the ability of the technology to fix, or heal, outages, the deployment of GE’s switch controllers is expected to reduce the number of customers affected by failures on main line circuits by half.
