Duke Energy Nets SAIDI Gains

Florida utility deals with thunderstorms with a new, multipronged strategy for operations centers, work crews and substation automation.

Duke Energy is on pace to reduce its SAIDI by 20 minutes since 2018. This is not a simple thing to do when you are serving nearly 1.9 million customers in a region that experiences the most thunderstorms in the United States. To make this much progress in not much time, the utility implemented a multi-part strategy involving sophisticated sectionalizing of its distribution system, a restructuring of territory management, better repair process discipline, storm hardening, substation optimization and next-generation power grid planning.
