Duke Energy Florida reported that its self-healing technology prevented more than 280,000 extended power outages for customers in 2025. The company said this technology also saved customers over 300,000 hours of outage time during the year.
Self-healing systems are designed to detect outages and automatically reroute power to restore service faster or avoid outages entirely. According to Duke Energy Florida, these systems can reduce the number of affected customers by up to 75% and often restore power in less than a minute.
Currently, more than 1.7 million of Duke Energy Florida’s two million customers benefit from this technology. This represents about 82% of its customer base, which is twice as many as were served by the system in 2020.
During the 2024 hurricane season, self-healing technology helped save millions of hours in outage time: approximately 3.3 million hours during Hurricane Milton, around 1.8 million hours during Hurricane Helene, and about 208,000 hours during Hurricane Debby.
“Even without major storms, we see the benefits of self-healing technology,” said Melissa Seixas, Duke Energy Florida state president. “It helps our system respond automatically when something goes wrong, often restoring power in seconds and reducing how many customers are affected. That means fewer outages, faster restoration and a more reliable experience for our customers year-round.”
The company noted that factors such as vegetation growth, wildlife activity or vehicles striking power lines can also impact reliability outside of storm events. Duke Energy Florida plans to continue expanding its use of self-healing technologies into 2026.
Duke Energy Florida operates as a subsidiary of Duke Energy and owns energy capacity totaling 12,300 megawatts across a service area covering roughly 13,000 square miles in Florida.
Duke Energy serves electric utility customers across six states and has natural gas operations in four states. The company continues investing in grid upgrades and cleaner generation sources while working toward an energy transition focused on reliability and value for its customers.
