Key Terms

kilowatt-hours (kWh), storm cost recovery charge, true up, Inflation Reduction Act, +1 more

5 terms

kilowatt-hours (kWh) technical

"lowering residential customer bills by approximately $50, or 25%, for every 1,000 kilowatt-hours (kWh) of energy"

A kilowatt-hour (kWh) is a measure of energy equal to using one thousand watts for one hour — like running ten 100‑watt light bulbs for an hour or charging an electric car enough to drive a few miles. Investors use kWh to compare and forecast energy production, consumption and costs: it ties directly to utility revenue, fuel and operating expenses, pricing of electricity and the demand outlook that affects company value.

storm cost recovery charge regulatory

"An approximately $33 decrease from the early removal of the storm cost recovery charge associated with the company's response"

A storm cost recovery charge is a fee added to customer bills or an accounting adjustment that lets a regulated company recoup expenses from repairing damage and restoring service after severe weather. For investors, it matters because the charge can improve a company’s cash flow and reduce the hit to earnings from unexpected storm costs, but it also depends on regulatory approval and can affect customer rates and demand.

true up financial

"FPSC recently approved a filing to true up the difference between the storm cost recovery charge amount collected"

A true up is an adjustment made to reconcile a previously estimated or provisional amount with the actual final figure, such as final costs, taxes, or share counts. For investors it matters because true-ups can create one-time charges or credits that change reported earnings, cash flow, or liabilities and may affect valuation and future forecasts; think of it like balancing a bank statement to correct earlier estimates.

Inflation Reduction Act regulatory

"Passing on $65 million in Inflation Reduction Act tax credits to customers"

The inflation reduction act is a law designed to lower the overall increase in prices for goods and services in an economy, helping to keep the cost of living more stable. For investors, it matters because reducing inflation can lead to a healthier economy, potentially making investments safer and more predictable by preventing prices from rising too quickly.

megawatts technical

"Duke Energy Florida, a subsidiary of Duke Energy, owns 12,500 megawatts of energy capacity"

A megawatt is a measure of electrical power equal to one million watts, describing how much electricity a plant or device can generate or use at a single moment. Investors use megawatts to compare the size and earning potential of energy projects—larger capacity usually means more electricity to sell—much like comparing the horsepower of engines to judge how much work they can do. Knowing megawatts helps assess scale, revenue potential, and grid impact of energy assets.

ST. PETERSBURG, Fla., May 29, 2026 /PRNewswire/ -- Duke Energy Florida will implement its third rate reduction of 2026 from June through September, lowering residential customer bills by approximately $50, or 25%, for every 1,000 kilowatt-hours (kWh) of energy used when compared to January.

The breakdown:

Below is an outline of how these rate reductions have and will continue to appear on the bills of Duke Energy Florida's typical residential customers using 1,000 kWh per month:

• February 2026: An approximately $33 decrease from the early removal of the storm cost recovery charge associated with the company's response to hurricanes Debby, Helene and Milton

• March 2026: An approximately $11 decrease instituted by the company every March through November to help customers save money during times when energy use is typically higher

• June 2026: An approximately $6 decrease reflecting the difference between the storm cost recovery amount collected and the actual amount incurred by the company (effective through September 2026)

• Total: An approximately $50 decrease

Our view:

"We know it feels like every bill is higher right now – from housing to groceries to power – and that can put a strain on families. We also understand that our customers depend on us to provide safe, reliable energy, day in and day out, at the lowest possible price," said Melissa Seixas, Duke Energy Florida state president. "This is the third rate reduction for our customers this year, supporting our commitment to delivering positive outcomes that have a real, tangible impact on their wallets and in their lives."

True up explained:

Duke Energy Florida customers – like all investor-owned utility customers – only pay for the actual costs associated with the company's storm response. The Florida Public Service Commission (FPSC) recently approved a filing to true up the difference between the storm cost recovery charge amount collected (approximately $1 billion) and the actual amount incurred by the company (approximately $915 million) following the 2024 hurricane season. This true up will flow back to customers as a decrease in fuel rates from June through September 2026.

For 1,000-kWh residential customers, the true up – combined with FPSC-approved recovery costs associated with the company's newest solar energy site – will result in an approximately $6 net decrease on bills when compared to March through May 2026.

Commercial and industrial customers can also expect bill decreases ranging from 3.3% to 7.4% when compared to March through May 2026, though the specific impact will vary depending on several factors.

More savings:

Duke Energy Florida continues to identify new and creative ways to create additional savings for customers, including:

• Making efficiency improvements at many of its natural gas plants, saving customers $340 million in fuel costs.

• • This translates to $10 savings on customers' monthly bills.

• Completing four new solar energy sites – in Madison, Hernando and Sumter counties – saving customers another $1 billion from displaced fuel costs.

• Passing on $65 million in Inflation Reduction Act tax credits to customers, which will only increase as more solar energy sites come online.

• • This saves residential customers at least $2.50 per 1,000 kWh.

Help is available:

While Duke Energy Florida is focused on keeping its own costs in check, the company is committed to connecting customers with practical ways to save energy and manage their bills, including flexible payment plans. For more information, please visit duke-energy.com/HereToHelp.
