Duke Energy Florida has announced that its 2025 infrastructure investments will result in more than $1 billion in savings for customers. The company stated that by March 2026, the average residential customer’s monthly bill will decrease by about $44, or 22%, per 1,000 kilowatt-hours compared to January.
The utility completed a series of projects in 2025 aimed at improving energy reliability and expanding capacity to meet increasing demand. These initiatives include adding new renewable energy sites, upgrading natural gas power plants, reinforcing infrastructure against storms, and introducing innovative carbon-free technologies.
Clean energy expansion accounted for a significant portion of the savings. Three new solar sites in Hernando, Sumter, and Madison counties are now operational, leading to an estimated $750 million reduction in fuel costs. Duke Energy Florida plans to complete eight more solar sites by the end of 2027.
Power plant upgrades were also finished at several facilities. According to the company, these improvements increased output without requiring construction of new plants and are expected to save customers over $350 million overall—equivalent to about $10 per month on their bills.
In terms of technological innovation, Duke Energy Florida successfully tested what it describes as the nation’s first system capable of producing, storing, and using entirely green hydrogen at its DeBary solar site. This project is intended to diversify power generation options and advance efforts toward carbon-free energy.
To address storm resilience, crews replaced more than 2,000 poles with stronger materials and expanded self-healing technology on the grid. The company reports that this prevented over 215,000 hours of outages during 2025.
“Duke Energy Florida is investing wisely, modernizing responsibly and doing all we can to keep costs as low as possible. Every investment we made in 2025 shared a common purpose to deliver reliable energy while keeping rates low for the customers and communities we serve. As we head into 2026, our priorities remain the same. We’ll continue projects and improvements that will lower bills and boost reliability,” said Melissa Seixas, president of Duke Energy Florida.
Duke Energy Florida provides electricity across a service area spanning approximately 13,000 square miles in Florida and serves about two million customers. Its parent company Duke Energy operates utilities serving millions across six states and owns over 55 gigawatts of generating capacity nationwide.
