Central Florida Electric Rates in 2026: What Duke Energy, OUC, and SECO Customers Need to Know

The Utility Landscape for Central Florida in 2026

Central Florida homeowners are served by several different utilities depending on where they live, and each is navigating its own rate environment heading into 2026.

Duke Energy Florida is the largest electricity provider in the region, serving much of Orange, Osceola, Seminole, and Polk counties. Duke has been investing heavily in solar generation, and those investments — combined with favorable fuel cost adjustments — have positioned the utility for relative rate stability heading into 2026. Duke customers have also seen the company pass through some fuel cost savings in recent rate cycles.

OUC (Orlando Utilities Commission) serves the city of Orlando and surrounding areas. As a municipal utility, OUC operates somewhat differently from investor-owned utilities — it has been actively building out renewable generation and smart grid infrastructure, with an eye toward long-term rate stability. OUC customers typically see more predictable rates than customers of larger regional utilities subject to fuel market swings.

SECO Energy serves rural portions of Seminole, Lake, and surrounding counties as an electric cooperative. As a member-owned cooperative, SECO passes rate changes through to members based on its actual cost structure, including wholesale power costs from its generation cooperative.

Regardless of which utility you’re served by, one principle applies universally: Florida’s climate means your HVAC system drives the majority of your electric bill, and no utility rate increase or rate structure change affects your budget as much as what your AC system does with electricity.

Why Your HVAC Bill Is What It Is

Here’s the number that tends to surprise people: in Central Florida, your HVAC system typically accounts for 50–65% of your total electric bill during summer months. During the shoulder months of October and April, that percentage drops — but even in a mild month, heating and cooling represent a plurality of most households’ electricity consumption.

This is why HVAC efficiency matters more here than almost anywhere else in the country. The same home with a 10 SEER air conditioner versus a 16 SEER unit will see a 30–40% difference in cooling energy use. Over the course of a Central Florida summer, that difference can easily add up to $300–500 or more — depending on home size, usage patterns, and current rates.

SEER ratings (Seasonal Energy Efficiency Ratio) are the standard measure of AC efficiency. As a rough rule of thumb, every 1 SEER point of improvement reduces cooling energy consumption by about 7%. The minimum federal standard for new residential equipment rose to SEER2 14.3 in the Southeast in 2023. Many older Central Florida systems installed 10–15 years ago run at SEER ratings well below current minimums.

What’s Driving Rate Pressure Across Florida

Florida utilities have faced several cost pressures in recent years that have influenced rate trends statewide:

Hurricane recovery costs — Major storm events, including recent hurricane seasons, generate billions in grid repair and restoration costs. Florida utilities recover these through storm surcharges and rate adjustments. Customers in affected areas see these costs appear as separate line items on their bills and persist for months or years after the event.

Grid hardening investments — In response to storm vulnerability, Florida utilities are investing heavily in underground lines, stronger poles, and distribution infrastructure designed to reduce outage duration and frequency. These investments improve long-term resilience but add to current-period rate pressure.

Fuel cost volatility — Gas-fired generation remains a large part of Florida’s electricity mix, and natural gas prices can shift significantly from year to year. Utilities pass fuel costs through to customers, meaning rate bills can vary with commodity markets even when base rates are stable.

Solar expansion — The counterweight to cost pressures is an ongoing buildout of solar generation across Florida. As more solar comes online, utilities can reduce fuel purchases and, in favorable rate cycles, pass those savings to customers.

Strategies to Control Your Bill Regardless of What Rates Do

You can’t control what the utilities charge, but you have significant control over how much electricity you consume. HVAC-focused strategies typically offer the highest return:

Smart thermostat management — 78°F when home, 80–82°F when away is the Department of Energy’s recommended Florida summer setting. A programmable or smart thermostat automates this without any daily thought. The difference between 72°F and 78°F in a Florida summer can easily represent 20–30% of your cooling bill.

Annual professional maintenance — A well-maintained system runs measurably more efficiently than a neglected one. Dirty coils, low refrigerant, and worn components all increase energy consumption while reducing comfort. Annual tuneups pay for themselves in energy savings across a Central Florida summer.

Air sealing — Leaky ductwork and building envelope gaps are often the single highest-ROI improvement available. Conditioned air escaping through duct connections in an unconditioned attic is money being spent to cool the attic, not your living space.

Filter discipline — Replacing your air filter every 1–3 months takes five minutes and ensures your system isn’t fighting restricted airflow all season.

System upgrade economics — If your system is 12–15 years old, the math often favors replacement. The federal 25C energy efficiency tax credit covers up to 30% of the cost of qualifying high-efficiency HVAC equipment through 2032. When you factor in energy savings plus the tax credit, the payback period on a high-SEER upgrade is often shorter than homeowners expect.

Making the Right Call for Your Home

The starting point for most homeowners is understanding what they currently have. A/C Mechanix can evaluate your existing system’s efficiency, age, and condition, and give you a straight answer on whether tuning up what you have or investing in an upgrade makes more financial sense.
