Electric Costs in Florida Are Changing
Many homeowners across Florida have noticed their electric bills rising in recent years.
Over the past several years, residential electric costs have increased in noticeable steps rather than all at once.
These changes often appear as a combination of base-rate adjustments along with additional charges related to fuel costs, storm recovery, and long-term infrastructure upgrades.
Several widely reported data points help illustrate these changes:
Combining base rates, fuel adjustments, and infrastructure costs, the typical residential Duke Energy bill increased roughly 30-40% between 2020 and 2025, depending on timing and usage.
Fuel cost adjustments increased during periods of higher natural gas prices, which utilities are generally permitted to pass through to customers.
Duke Energy customers experienced multiple rate adjustments between 2021 and 2026 through base-rate approvals and fuel cost changes.
Actual bills vary widely depending on home size, usage patterns, and seasonal air-conditioning demand.
However, these broader trends help explain why many Florida homeowners feel electricity costs rising faster than expected.
A key challenge for homeowners is that future rate changes are not set by the household.
Instead, they are approved through regulatory processes that most customers rarely see and often only become aware of after changes take effect.
Why Electric Rates Increase Over Time
Electricity pricing is influenced by several long-term factors, including:
Grid hardening and reliability upgrades
Utilities invest in strengthening poles, transmission lines, substations, and other infrastructure to improve reliability; particularly in hurricane-prone regions.
Fuel cost adjustments
Electric utilities use fuels such as natural gas to generate electricity. When fuel prices change, utilities are typically allowed to pass those adjustments through to customers.
Population growth
Florida continues to experience rapid population growth, which increases overall electricity demand and requires additional generation capacity and equipment. Florida’s population has grown by more than 1.5 million residents since 2020.
Large energy users, including data centers
Facilities supporting cloud computing, artificial intelligence systems, and other high-demand operations require significant electricity and increase baseline demand on the grid.
These drivers are long-term in nature, which is why electric rate increases are often viewed as structural rather than temporary.
Why This Matters More in Florida
Rising electric rates affect homeowners everywhere, but Florida households often feel the impact more due to:
High air-conditioning usage across a long cooling season. Cooling a home in Florida often accounts for 45-50% of total household electricity consumption, depending on the home’s size, insulation, and thermostat settings.
Exposure to hurricanes and severe storms, which increase infrastructure costs
Because of these factors, even modest increases in per-kilowatt-hour rates can translate into noticeable monthly changes for Florida homeowners.
The Two Paths Homeowners Typically Face
When electricity costs feel unpredictable, most homeowners end up on one of two general paths.
Option 1: Stay fully on the electric utility
This is the default path for most households.
Bills are paid month-to-month
Rates change over time
Costs remain variable
Homeowners have limited long-term control over pricing
This approach isn’t “wrong” it simply means remaining exposed to future rate adjustments.
Option 2: Produce some of your own power
Some homeowners explore ways to stabilize part of their electricity cost.
The goal is often predictability rather than maximum savings
Similar to choosing fixed expenses instead of fully variable ones
Solar is one of the most common ways households do this
This does not eliminate the utility entirely, but it can reduce how much of a home’s total energy cost is subject to future utility pricing.
For homeowners who explore this option, the process typically moves step by step, with opportunities to review details along the way before anything is finalized.
What a Solar TPO Is (High-Level)
One option homeowners sometimes consider is a Solar TPO, which stands for Third-Party Owned solar.
At a high level:
The homeowner does not purchase a solar system
There is no loan and no upfront cost required to enter into the agreement
A third party owns and maintains the equipment
The homeowner pays for electricity produced at a set rate
In many cases, the third party maintains system liability, and homeowner insurance premiums do not increase though policies vary
Rather than owning equipment, the homeowner is choosing a different way to source a portion of their electricity.
Like most long-term service agreements, the process involves confirming eligibility and reviewing final details before any installation decisions are made.
Why Some Homeowners Prefer a TPO Over Buying Solar
For homeowners who are interested in solar but hesitant to buy a system outright, a TPO can feel like a more financially conservative option.
Common reasons include:
No maintenance responsibility
No repair risk tied to ownership
No long-term equipment ownership obligations
Greater cost predictability over time
Because the system is owned and managed by a third party, many homeowners view a TPO less as a purchase decision and more as a risk-management approach to long-term energy costs.
Common Questions Homeowners Ask
-
When utility rates were more stable, fewer homeowners explored alternatives. As rates have risen more quickly in recent years, third-party ownership models have become more widely discussed. These structures have been common in states like California for many years.
Industry data indicates that roughly 45-50% of residential solar installations nationwide use third-party ownership structures. Adoption rates for commercial customers are even higher, often estimated between 75-80%.
-
No. Solar and TPOs specifically depend on home characteristics, usage patterns, and long-term plans. Some homes are better suited than others. Participation also depends on meeting standard program eligibility requirements.
-
Usually yes. With a solar TPO, the home remains connected to the grid and continues to receive a utility bill for the connection fee and potentially other fixed costs. For many Florida homeowners in 2026, this is often in the range of $10-20 per month, though actual amounts vary.
Many homeowners find that reviewing their own usage alongside these broader trends provides helpful clarity. This typically includes confirming eligibility before any next steps are finalized.
Closing Thoughts
Rising electricity costs have led many Duke Energy customers to take a closer look at how their energy is priced and what alternatives exist.
By understanding recent rate trends and how different energy options work at a high level, homeowners can approach future conversations about their own electricity usage and numbers, with clearer expectations.
Some ultimately decide to remain fully with the utility, while others explore ways to stabilize part of their electricity cost over time.
