Throughout 2025, Duke Energy Florida completed targeted infrastructure projects that collectively will save customers more than $1 billion. These initiatives include upgrades to transmission lines, distribution circuits and substations, as well as the deployment of advanced monitoring systems. By March 2026, the average residential customer using 1,000 kWh per month will see bills drop by $44, or 22%, compared with January readings, reflecting the avoided costs from fuel savings and operational efficiencies achieved through these upgrades.

Duke Energy Florida added three new solar facilities in Hernando, Sumter and Madison counties during 2025, displacing enough fossil‐fuel generation to save customers an estimated $750 million in avoided fuel costs. Major upgrades at multiple natural gas plants, which boost output to levels equivalent to a new facility without new construction, will yield an additional $350 million in fuel savings and shave roughly $10 off monthly bills. By the end of 2027, eight more solar sites are scheduled to come online, further lowering long‐term customer rates.

In 2025, crews replaced over 2,000 wooden poles with stronger composite materials and expanded self‐healing grid technology, preventing more than 215,000 outage hours. At the DeBary solar site, Duke Energy Florida demonstrated the nation’s first fully integrated system for producing, storing and using 100% green hydrogen, advancing its carbon‐free energy portfolio. These measures not only bolster resilience against severe weather but also position the utility for future clean energy integration.
