By Ashley Robinson Florida’s electricity network is powered by a combination of large investor-owned companies and community-owned municipal utilities. These providers do much more than generate and distribute electricity. They strengthen power lines against hurricanes, operate nuclear and solar facilities, maintain local grids and help restore services after severe storms.
Unlike telecom or insurance services, Florida residents normally cannot select their electricity company. The provider is determined by the service territory in which a property is located. For 2026, the following five companies stand out based on customer base, service area, generating capacity, reliability, infrastructure and overall importance to Florida’s economy.
1. Florida Power & Light Company
- Headquarters: Juno Beach, Florida
- Main Service Area: South Florida, the Atlantic Coast, Southwest Florida and Northwest Florida
- Customers: More than 6 million customer accounts
Florida Power & Light Company, commonly known as FPL, is the largest electric utility in Florida and the United States. It supplies electricity to more than six million customer accounts, representing approximately 12 million people across the state.
FPL’s enormous service territory includes Miami-Dade, Broward, Palm Beach, Martin, St. Lucie, Lee, Collier and numerous other counties. Following the integration of the former Gulf Power service territory, FPL also has a major presence in Northwest Florida, including areas around Pensacola, Panama City and Fort Walton Beach.
The company uses a diverse energy mix that includes natural gas, nuclear energy, solar power and battery storage. It operates the Turkey Point and St. Lucie nuclear power facilities and has developed numerous solar energy centres across Florida.
FPL is the principal subsidiary of NextEra Energy. Its large customer base, extensive generation network and continuing investment in hurricane-resistant infrastructure make it Florida’s most important power company in 2026. Florida Power & Light
2. Duke Energy Florida
- Regional Headquarters: St. Petersburg, Florida
- Main Service Area: Central Florida, the Tampa Bay region, the Nature Coast and the Big Bend area
- Customers: Approximately 2 million customers
Duke Energy Florida is the state’s second-largest investor-owned electric utility. The company supplies electricity to approximately two million residential, commercial and industrial customers across a service territory covering about 13,000 square miles and portions of 35 counties.
Its main service areas include communities around St. Petersburg, Clearwater, Ocala, Crystal River and parts of Greater Orlando. The company also has an important presence along Florida’s Nature Coast and in the Big Bend region.
Duke Energy Florida owns approximately 12,500 megawatts of generating capacity. Its electricity portfolio includes natural gas, solar power and other generating resources. It has been expanding solar facilities while strengthening substations, power lines and distribution networks against hurricanes.
More than 1.7 million Florida customers now benefit from Duke Energy’s self-healing grid technology. This system can identify a power disruption and automatically redirect electricity, sometimes restoring service in less than a minute. Duke Energy Florida is a subsidiary of Duke Energy Corporation.

3. Tampa Electric
- Headquarters: Tampa, Florida
- Main Service Area: Hillsborough County and parts of Polk, Pasco and Pinellas counties
- Customers: Approximately 870,000 customers
Tampa Electric, frequently called TECO, is one of the leading electricity providers in West-Central Florida. Established in 1899, the company serves approximately 870,000 customers, including around 92,000 businesses.
Its 2,000-square-mile service territory covers Hillsborough County and portions of Polk, Pasco and Pinellas counties. Important communities within its network include Tampa, Plant City, Temple Terrace and parts of the wider Tampa Bay region.
Tampa Electric operates more than 5,000 megawatts of generating capacity. It has been modernising its power stations, developing additional solar projects and strengthening its distribution network. Its energy-efficiency programmes help households and businesses monitor consumption, shift usage away from high-demand periods and control monthly electricity costs.
The company reports service reliability of approximately 99.98%. Tampa Electric is wholly owned by Emera, a Canadian energy company, but its principal operations and customer base remain centred in Florida. Tampa Electric
4. JEA
- Headquarters: Jacksonville, Florida
- Main Service Area: Jacksonville and portions of Clay, Nassau and St. Johns counties
- Electric Customers: More than 540,000
JEA is Florida’s largest municipal utility and one of the largest community-owned utilities in the United States. It supplies electricity to more than 540,000 customers and provides water, wastewater and reclaimed-water services to Jacksonville and surrounding communities.
Its electric service territory covers approximately 905 square miles. The network includes four generating plants, 744 circuit miles of transmission infrastructure and more than 7,500 miles of distribution lines.
JEA is owned by the community rather than private investors. It is governed by a board appointed through the City of Jacksonville. This public ownership model allows the utility to focus on local service, infrastructure development and reasonable rates.
JEA has installed smart electric meters for its customers and operates eight solar farms. The company has also reduced its carbon emissions substantially by closing older generating facilities and increasing the use of cleaner energy sources. Its combination of electric, water and sewer operations makes JEA particularly important to Northeast Florida. JEA
5. Orlando Utilities Commission
- Headquarters: Orlando, Florida
- Main Service Area: Orlando, St. Cloud and portions of unincorporated Orange and Osceola counties
- Total Utility Accounts: More than 400,000
Orlando Utilities Commission, better known as OUC–The Reliable One, is Florida’s second-largest municipal utility. Established in 1923, it provides electricity, water, chilled water, lighting and solar services to more than 400,000 accounts.
OUC’s electric service territory covers approximately 419 square miles and includes Orlando, St. Cloud and parts of unincorporated Orange and Osceola counties. Around 67% of its electric network is underground, helping reduce exposure to falling trees, strong winds and other storm-related risks.
Based on 2025 performance data, OUC reported the highest electric reliability in Florida for the second consecutive year. The utility maintains more than 3,000 miles of electric transmission and distribution lines and continues to replace older wooden poles with stronger concrete poles.
OUC is a good example of a locally governed utility combining reliable electricity with water and other essential community services. Orlando Utilities Commission
Factors Considered for This Ranking
The companies were ranked using several important factors:
- Number of electricity customers
- Size and importance of the service territory
- Generating capacity
- Power reliability and storm readiness
- Grid modernisation
- Investment in solar and cleaner energy
- Range of utility services
- Importance to Florida’s major population centres
Conclusion
Florida Power & Light leads the ranking because it supplies electricity to more than half of Florida’s population and operates the state’s largest power network. Duke Energy Florida follows with a vast territory covering Central and northern parts of the state, while Tampa Electric remains the main electricity provider for West-Central Florida.
JEA and OUC may serve smaller territories, but both are nationally significant municipal utilities with strong local infrastructure. Together, these five companies form an essential part of Florida’s electricity system, powering millions of homes, businesses and public services across the state.
