ST. PETERSBURG, Fla., Dec. 29, 2025 /PRNewswire/ -- Throughout 2025, Duke Energy Florida teams have completed many targeted investments designed to boost energy reliability, reduce customer rates and expand capacity to meet growing energy demands.

In addition to savings from the grid enhancing investments, the average Duke Energy Florida residential customer will see their monthly bill decrease an average of $44 per 1,000 kWh by March 2026, compared to January.

A breakdown of the investments and how the projects serve customers: Duke Energy Florida's investments in 2025 include:
