Duke Energy Florida traces its origins to Florida Power Corporation, founded in 1899 in St. Petersburg, Florida. The company was established to provide electric service to communities in central and northern Florida during a period of rapid growth in the state. The utility celebrated its 125th anniversary in 2024.
Florida Power Corporation expanded its service territory and generation capacity throughout the 20th century. The company developed coal-fired and nuclear generating stations to meet growing electricity demand. Its service territory covers a large area of central and northern Florida, including the Tampa Bay area, the Space Coast, and Gulf Coast communities.
In the 1970s, Florida Power Corporation developed the Crystal River Nuclear Plant near Crystal River, Florida. The single-unit pressurized water reactor began commercial operation in 1977 and provided baseload nuclear generation for more than three decades. In 2009, during a steam generator replacement project, the reactor's concrete containment building developed cracks. The damage proved too costly to repair. Duke Energy announced the permanent retirement of the Crystal River Nuclear Plant in February 2013, shortly after completing the merger with Progress Energy.
In 2000, Florida Power Corporation merged with Carolina Power and Light Company to form Progress Energy, Inc., a Raleigh-based electric utility holding company. Progress Energy operated two regulated electric utilities: Progress Energy Carolinas in eastern North Carolina and South Carolina, and Progress Energy Florida in central and northern Florida.
In 2012, Duke Energy Corporation completed its merger with Progress Energy, Inc., creating the largest electric utility in the United States by customer count at the time. Duke Energy renamed Progress Energy Florida as Duke Energy Florida.
Following the 2012 merger, Duke Energy Florida accelerated its clean energy transition. The utility retired its remaining coal-fired generating units and replaced retired capacity with natural gas combined-cycle plants, utility-scale solar facilities, and battery energy storage systems. Florida's abundant sunshine makes solar generation economically attractive, and Duke Energy Florida has invested heavily in solar development.
The utility has also invested in grid hardening to address Florida's hurricane risk. Measures include undergrounding distribution lines in vulnerable areas, installing stronger utility poles, deploying smart grid technology for outage detection, and building storm response capabilities. Hurricanes remain a significant operational challenge, with major storms capable of causing widespread damage to the electric distribution system.

What are Duke Energy's key initiatives?
Duke Energy's key initiatives include its $103 billion capital plan to build 15 gigawatts of new generation capacity by 2031, securing data center electric service agreements (7.8 gigawatts signed with 15.4 gigawatts in pipeline), expanding battery storage to 5,600 megawatts by 2031, targeting 4,000 megawatts of new solar by 2034, extending nuclear plant licenses by 20 years, and achieving net-zero carbon emissions by 2050.
What controversies has Duke Energy faced?
Duke Energy has faced regulatory challenges including the North Carolina Utilities Commission pausing its solar procurement process in April 2026, criticism over extending coal operations and increasing natural gas reliance, disputes in Indiana over alleged over-collection of $89 million, and public opposition to proposed rate increases. The company has also drawn scrutiny over its data center contracts and their impact on residential customer bills.
Duke Energy Florida's sustainability strategy is tied to Duke Energy Corporation's commitment to achieve net zero carbon emissions by 2050. The utility has fully retired its coal-fired generating units and the Crystal River nuclear plant, transitioning to a generation mix of natural gas, solar, and battery storage.
Solar energy is a growing part of the generation fleet. Duke Energy Florida has developed utility-scale solar projects across central and northern Florida, taking advantage of the state's solar resources. The utility has also invested in battery energy storage systems to complement solar generation and improve grid reliability.
The utility offers the Clean Energy Impact program, a renewable energy certificates (RECs) program that allows customers to support renewable energy development and reduce their carbon footprint.
Energy efficiency and demand response programs help customers reduce consumption and manage peak demand. The utility offers rebates for energy-efficient appliances, smart thermostat programs, and demand response incentives.
Grid hardening investments address Florida's hurricane risk. Undergrounding distribution lines, installing stronger poles, and deploying smart grid technology improve resilience to severe weather. These investments reduce outage duration and improve customer satisfaction following major storms.
The Duke Energy Foundation has provided grants to support Florida's economic competitiveness, workforce development, and community programs.
Specific awards for Duke Energy Florida as a standalone utility are not widely published in available sources. The Edison Electric Institute has recognized Duke Energy for emergency response and outage restoration, particularly following hurricane events in Florida. The utility's clean energy transition efforts, including coal plant retirements and solar expansion, have been noted by industry publications.
Duke Energy Florida does not manufacture consumer products, so product recalls do not apply. The utility has faced regulatory, environmental, and operational controversies.
Crystal River Nuclear Plant retirement: The 2009 steam generator replacement project at the Crystal River Nuclear Plant caused cracking in the reactor's concrete containment building. The damage proved too costly to repair, and Duke Energy announced the plant's permanent retirement in February 2013. The retirement resulted in significant stranded costs that Duke Energy Florida sought to recover through customer rates, creating regulatory disputes with the FPSC and criticism from consumer advocacy groups.
Rate increase disputes: Duke Energy Florida has filed rate cases with the FPSC to recover infrastructure investments, including grid hardening and clean energy transition costs. Consumer advocacy groups have raised concerns about the impact of rate increases on residential customers, particularly low-income households and seniors on fixed incomes.
Hurricane response criticism: Following major hurricanes, Duke Energy Florida has faced criticism regarding the speed of power restoration and the adequacy of storm preparation. The utility has invested in grid hardening and storm response capabilities in response, but severe hurricanes continue to test the system.
Coal ash and environmental legacy: Although Duke Energy Florida has retired its coal plants, the utility continues to manage coal ash disposal sites from historical operations. Environmental groups have raised concerns about groundwater contamination from coal ash ponds.
Nuclear decommissioning: The Crystal River Nuclear Plant is being decommissioned. The decommissioning process is regulated by the U.S. Nuclear Regulatory Commission and involves managing spent nuclear fuel and site remediation.
Service reliability concerns: Customers have raised concerns about service reliability during severe weather events. The utility's grid hardening investments are designed to address these concerns, but Florida's hurricane exposure means outages will continue during major storms.
