The 30-Second Verdict
Florida Power & Light serves roughly 5.8 million customers across South and East Florida — the largest utility in the state. Duke Energy Florida serves about 1.9 million customers across Central Florida including Tampa Bay. If you live in one service territory, you generally can't switch — but understanding the differences matters for solar ROI, net metering value, and what to expect after a hurricane.
Head-to-Head Breakdown
Florida Power & Light (FPL)
Pros
- Largest utility in Florida — massive investment in grid hardening post-Hurricanes Irma and Ian
- Among the lowest residential rates in Florida — consistently near or below national average
- FPL SolarTogether community solar program available statewide
- Aggressive smart meter and automated outage detection reduces restoration time
- FPL EV charger rebate programs support Florida's growing EV market
- Strong net metering — 1:1 retail rate credit for solar customers through at least 2029
Cons
- Service territory does not cover Tampa Bay or Central Florida
- Some customers report customer service challenges given scale of operations
- Transmission infrastructure still being upgraded in rural South Florida counties
- Rate cases have historically faced pushback from consumer advocates
Duke Energy Florida
Pros
- Serves Tampa Bay, Orlando suburbs, and Central Florida's growing residential market
- Duke Energy Progress Reliability program has improved outage minutes year-over-year
- Energy Neighbors solar program and Duke EV rebates available for Florida customers
- Strong commercial and industrial rate options for business owners
- Active grid modernization investment in storm-prone Pinellas and Hillsborough counties
- Multiple payment assistance programs for low-income and elderly Florida residents
Cons
- Residential rates slightly higher than FPL on average
- Net metering policy changes in 2023 reduced solar export credit value over time
- Smaller grid hardening budget relative to FPL given smaller customer base
- Central Florida customers experienced extended outages after Hurricane Ian in 2022

Frequently Asked Questions
Can I choose between FPL and Duke Energy Florida for my home?
No. Florida electric utilities operate as regulated monopolies within defined service territories. If your home is in FPL territory (South and East Florida), you are an FPL customer. If you're in Central Florida or the Tampa Bay area, Duke Energy Florida is your utility. You can verify your utility by entering your address on the Florida Public Service Commission's website at floridapsc.com. The only true 'choice' Florida homeowners have is whether to install solar and reduce dependence on grid power.
How did FPL and Duke Energy perform after major Florida hurricanes?
After Hurricane Ian in 2022, Duke Energy Florida had approximately 250,000 customers lose power in the Charlotte and Lee County areas, with many restored within 5 days. FPL, despite Ian's impact in its South Florida territory, leveraged its multi-billion-dollar grid hardening program to restore most customers faster than historical storm benchmarks. FPL's 'Storm Secure Underground Program' — replacing overhead lines with underground cables — has meaningfully reduced outage duration in completed neighborhoods.
Does Florida's net metering law change my solar ROI with either utility?
Yes, significantly. Florida's SB 1024 (effective 2023) changed net metering for new solar customers — instead of full retail credit, utilities now pay a reduced 'avoided cost' rate for excess solar exported to the grid. FPL and Duke both comply with this law, but FPL's avoided cost rate has historically been closer to retail than Duke's. For most Florida homeowners, this reinforces the value of battery storage (like Tesla Powerwall or Enphase IQ Battery) to self-consume solar rather than export it.
