By Ashley Robinson The air conditioner runs through a humid afternoon, water flows from the kitchen tap, and natural gas heats dinner on the stove. These daily services often feel automatic—until a hurricane damages power lines, a water main breaks or an unusually cold night pushes energy demand to its limit.
Florida’s utility industry includes investor-owned companies and publicly owned municipal providers. Some supply only electricity, while others deliver electricity, natural gas, water, wastewater and related services. Based on customer reach, infrastructure, service territory and importance to Florida’s economy, here are the top five utility companies in Florida for 2026.
1. Florida Power & Light Company
- Headquarters: Juno Beach, Florida
- Primary service: Electricity
- Customer base: More than 6 million customer accounts
- Parent company: NextEra Energy
Florida Power & Light Company, better known as FPL, is the largest electric utility in Florida and one of the largest in the United States. It provides power to approximately 12 million people.
FPL’s territory covers much of Florida’s Atlantic Coast, South Florida, Southwest Florida and several northwestern communities. Major service areas include Miami, Fort Lauderdale, West Palm Beach, Naples, Fort Myers, Sarasota and Pensacola.
The company operates a large mix of natural-gas, nuclear and solar generation facilities. Battery-storage technology has also become an increasingly important part of its system.
Hurricane preparation is central to FPL’s operations. The company replaces older wooden poles, strengthens transmission lines, clears vegetation and moves selected power lines underground. Its smart-grid technology can detect some problems automatically and redirect electricity around damaged equipment.
FPL is a subsidiary of NextEra Energy, which is also headquartered in Juno Beach. NextEra operates energy businesses outside Florida, but FPL remains its main regulated utility.
2. Duke Energy Florida
- Corporate headquarters: Charlotte, North Carolina
- Florida headquarters: St. Petersburg, Florida
- Primary service: Electricity
- Customer base: Approximately 2 million customers
Duke Energy Florida is the second-largest investor-owned electric utility operating in the state. It supplies electricity across a service territory covering roughly 13,000 square miles and 35 Florida counties.
Its strongest presence is in Central Florida, North Central Florida and parts of the Gulf Coast. St. Petersburg, Clearwater, Ocala and several communities around Greater Orlando are among its important markets.
Duke Energy Florida has around 12,300 megawatts of energy capacity. Its system includes natural-gas generation, solar facilities, battery projects, transmission lines and local distribution equipment.
The company has replaced thousands of older poles with stronger concrete or steel structures. It has also installed self-healing grid technology, which can identify a damaged section and reroute power to unaffected customers. A considerable portion of its primary power lines is underground.
Duke is particularly important because its territory includes densely populated coastal communities as well as rural regions where restoring power after a major storm can be difficult.
3. TECO Energy
- Florida headquarters: Tampa, Florida
- Parent-company headquarters: Halifax, Nova Scotia, Canada
- Main businesses: Tampa Electric and Peoples Gas
- Primary services: Electricity and natural gas
TECO Energy has a special position in Florida because its major operations cover both electricity and natural gas. Its two best-known utility businesses are Tampa Electric and Peoples Gas.
Tampa Electric serves approximately 870,000 customers across a 2,000-square-mile territory. Its service area includes Hillsborough County and portions of Polk, Pasco and Pinellas counties. The utility has more than 5,000 megawatts of generating capacity and uses natural gas, solar power and other energy sources.
Peoples Gas is Florida’s largest natural-gas distribution company. It serves roughly 445,000 to 470,000 homes and businesses through an extensive network of distribution mains. Unlike Tampa Electric, which is concentrated around Tampa Bay, Peoples Gas operates in numerous communities across the state.
TECO’s companies offer energy-efficiency programs, business utility services, outage support and assistance for eligible households. Their broad combination of electric and gas services places TECO among Florida’s most important utility organizations.
TECO Energy is owned by Emera, a Canadian energy company, but Tampa Electric and Peoples Gas continue to maintain headquarters and major operations in Tampa.
4. JEA
- Headquarters: Jacksonville, Florida
- Primary services: Electricity, water, wastewater and reclaimed water
- Main service area: Jacksonville and surrounding Northeast Florida communities
JEA is Florida’s largest municipally owned utility. It serves more than 520,000 electric customers and approximately 400,000 water customers in Jacksonville and nearby areas.
Its electric territory covers Jacksonville along with parts of Clay, Nassau and St. Johns counties. JEA owns generating facilities, transmission lines, substations and thousands of miles of local distribution lines.
JEA also operates one of Florida’s largest public water and wastewater systems. It delivers more than 120 million gallons of water on an average day. The water comes from the Floridan aquifer and is supplied through an extensive network of wells, treatment facilities and pipelines.
Because JEA is publicly owned, it does not have private shareholders. Its decisions are overseen locally, and its revenue is used for operations, infrastructure, debt payments and contributions to the City of Jacksonville.
Its combination of electric, water, sewer and reclaimed-water services makes JEA one of the most complete utility providers in Florida.
5. Orlando Utilities Commission
- Headquarters: Orlando, Florida
- Primary services: Electricity, water, chilled water, lighting and solar programs
- Main service areas: Orlando, St. Cloud and portions of Orange and Osceola counties
The Orlando Utilities Commission, commonly known as OUC, is a municipally owned, not-for-profit utility serving Central Florida. It provides more than 400,000 utility accounts across its electricity, water and related services.
OUC supports a demanding service territory containing residential neighborhoods, hospitals, hotels, entertainment districts and large commercial properties. Reliable electricity is particularly important in Orlando because tourism and hospitality businesses operate throughout the year.
The utility maintains more than 3,400 miles of electric transmission and distribution lines. It is strengthening poles, upgrading substations, clearing vegetation and adding smart-grid equipment to reduce the frequency and duration of outages.
OUC also provides drinking water, chilled-water services for large buildings, solar options and electric-vehicle charging programs. Its main office, known as Reliable Plaza, is located in downtown Orlando.
Can Florida Residents Choose Their Utility Company?
In most cases, no. A home’s electricity, gas and water providers are determined by its location. A Florida household may receive electricity from one utility, water from a city department and natural gas from another company.
Before renting or buying a home, residents should check:
- Which companies serve the address
- Current connection or deposit requirements
- Average seasonal electricity consumption
- Available budget-billing programs
- Outage reporting and emergency procedures
- Energy-efficiency rebates
- Solar connection and net-metering rules
- Water restrictions and conservation programs
Final Thoughts
FPL leads Florida’s utility sector because of its enormous customer base and statewide electric infrastructure. Duke Energy Florida follows with a large territory across Central and North Florida. TECO stands out for operating both electric and natural-gas businesses, while JEA and OUC provide broad public utility services in Jacksonville and Orlando.
Customers may not be able to select their provider, but they can still use efficiency programs, billing plans and conservation tools to manage monthly utility expenses.
