Duke Energy serves 8.2 million customers across six states, including Florida, Indiana, and the Carolinas, operating the largest U.S. transmission and distribution network with 320,000 miles of power lines. The company is implementing a $103 billion investment plan (2026–2030) focused on grid modernization, including self-healing technology to improve outage response.
In Florida, where Duke serves 2 million customers, the utility faces unique challenges from extreme weather events like hurricanes. These conditions highlight the importance of resilient infrastructure as Duke navigates regulatory scrutiny over its proposed tariffs for large energy users.
Why it matters: Duke Energy's operational scale and infrastructure investments reinforce its role in energy reliability and modernization. However, regulatory challenges in Florida could impact its ability to balance investment costs with customer affordability.
