Duke Energy Florida vs FPL head-to-head: rates per kWh, average monthly bill, reliability, and which utility wins for your zip code in 2026.
FPL is meaningfully cheaper than Duke Energy Florida in 2026. FPL's all-in residential rate is approximately 14.5¢/kWh vs Duke Energy Florida's ~17¢/kWh. For a typical 1,000 kWh monthly bill, that's a difference of about $25/month — roughly $300/year. The gap exists because FPL has a more efficient generation fleet, larger customer base, and significant solar investments.
No, you cannot switch utilities in Florida. Florida is a regulated electricity market, meaning your utility is determined by where you live — not by choice. If your address is in Duke Energy Florida's service territory, Duke is your only option, and the same applies to FPL. The only way to switch is to physically move to a different service area.
FPL serves eastern and southern Florida — including Miami, Fort Lauderdale, West Palm Beach, Naples, Fort Myers, and Daytona Beach. Duke Energy Florida serves central and northern Florida — including St. Petersburg, Clearwater, Lakeland, Ocala, and parts of Orlando. Tampa Electric (TECO) serves Tampa proper, and municipal utilities like JEA serve Jacksonville and OUC serves much of Orlando.
FPL generally reports better reliability metrics than Duke Energy Florida, with shorter average outage durations (SAIDI) and fewer outages per customer (SAIFI). FPL has invested heavily in grid hardening and underground lines through its Storm Protection Plan. Both utilities perform well after hurricanes by national standards, but FPL typically restores power faster.
For 1,000 kWh of usage, the average monthly bill is approximately $145 on FPL and $170 on Duke Energy Florida — a $25/month difference. For 1,500 kWh (a larger home with heavy AC use), the gap widens to roughly $40/month due to tiered rate differences.
