When the power goes out, electric utility customers want it back, and fast. Now it’s possible for a “smart” or “self-healing” electronic grid to reduce customers’ hours without power to just a few minutes. But adopting this technology is more complicated than flipping a switch.
A self-healing grid works by isolating the area where the impact of a power outage is the smallest and, ideally, restoring power to those customers almost immediately. Then, smart meters pinpoint those customers who remain without power so that the utility’s control center can send a crew out to fix the cause.
