Why Does My Electric Bill Keep Going Up?

Your bill isn’t determined by just one factor. It reflects how much electricity you use, the rate your utility charges for that electricity, and a handful of adjustments that can shift month to month.

Long cooling seasons, humidity, and extreme summer temperatures all increase energy demand. Even if your habits stay the same, a hotter summer can raise your bill.

This is a statewide pattern, not just a personal one. According to the U.S. Energy Information Administration, almost all Florida households use air conditioning, and the residential sector accounts for more than half of the electricity consumed in the state.²

Utilities periodically adjust rates for reasons such as:

• Fuel costs
• Grid maintenance
• Infrastructure improvements
• Regulatory changes

Rates and programs for Florida’s investor-owned utilities are reviewed by the Florida Public Service Commission, which also publishes consumer information and can help you identify your utility.³

Common contributors include:

• Older HVAC systems
• Poor insulation
• Aging water heaters
• Inefficient appliances
• Air leaks around windows and doors

Solar isn’t the only answer — sometimes efficiency work delivers meaningful savings on its own.

• Improve energy efficiency.
• Upgrade insulation.
• Service HVAC equipment.
• Use a smart thermostat.
• Consider solar if your home is a good candidate.

The point is to give yourself choices, not to assume solar is the only option.

Many people consider solar because it can reduce reliance on utility-supplied electricity. The impact depends on the home’s energy usage, system design, and other factors — there’s no one-size-fits-all guarantee.

Many homeowners wonder whether recent increases are temporary or part of a longer trend. One important development is the Florida Public Service Commission’s approval of a four-year rate plan for Florida Power & Light effective January 1, 2026 through December 31, 2029.¹

While the approved plan was substantially lower than FPL’s original request, the FPSC states it provides FPL approximately $945 million in additional annual revenues beginning in 2026 and an additional $705 million annually beginning in 2027, to support investments in Florida’s electric grid.¹

The impact on any individual household depends on electricity usage, fuel costs, and the other charges that appear on a monthly bill. It also depends on where in Florida you live — FPL serves distinct rate areas, and the approved plan did not affect them the same way.

The FPSC published specific figures for a typical residential 1,000-kWh monthly bill beginning in January 2026. Note that they move in opposite directions depending on service area:¹

The FPSC also states that solar and battery storage additions in 2027, 2028, and 2029 are subject to new cost-effectiveness criteria.¹

These figures describe a typical 1,000-kWh bill as published by the regulator. Your actual monthly bill can still vary based on energy usage, fuel prices, weather, and storm-related recovery costs, and HomeSolarGrid does not project what any specific bill will be in a future year.

Rather than framing this as “FPL is charging more,” it’s worth understanding where the money is intended to go.

The purpose of understanding utility rate changes isn’t to convince you that solar is the right answer. It’s to help you understand one important part of your home’s long-term energy costs.

For some homeowners, improving insulation or replacing an aging HVAC system may provide meaningful savings. For others, exploring solar may be worth considering. The right choice depends on your home, your energy usage, and your long-term goals.
