Duke Energy Florida announced that its 2025 infrastructure investments will result in more than $1 billion in energy cost savings for customers. The company completed a range of projects aimed at improving energy reliability, expanding capacity, and reducing customer rates.
By March 2026, the average residential customer is expected to see a monthly bill decrease of about $44 per 1,000 kilowatt-hours compared to January 2025. This represents a reduction of approximately 22%.
The company’s investments include several initiatives. Three new solar sites have been completed in Hernando, Sumter, and Madison counties. These projects are projected to save customers around $750 million by displacing fuel costs. Duke Energy Florida plans to add eight more solar sites by the end of 2027.
Upgrades at existing power plants have increased their output without constructing new facilities. These enhancements are estimated to provide more than $350 million in overall fuel savings and reduce monthly bills by $10 for customers.
At the DeBary solar site, Duke Energy Florida tested what it describes as the nation’s first system capable of producing, storing, and using entirely green hydrogen. The company says this supports a more diverse power generation portfolio and advances carbon-free energy goals.
To improve grid resilience against storms, crews replaced over 2,000 poles with stronger materials and expanded self-healing technology across the network. In 2025 alone, this technology prevented over 215,000 hours of outages.
Melissa Seixas, president of Duke Energy Florida said: “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.”
Duke Energy Florida serves about two million customers across a service area covering roughly 13,000 square miles in Florida with an owned capacity of 12,300 megawatts.
Its parent company Duke Energy is based in Charlotte, North Carolina and serves electric utility customers across six states with a total capacity of about 55,100 megawatts.
