Key Terms

5 terms

investment tax credits financial

"will result in more than $500 million in investment tax credits that"

Investment tax credits are government discounts on an investor’s tax bill tied to putting money into certain projects or assets, effectively returning a portion of the upfront cost as a tax saving. They matter to investors because they improve after-tax returns and can make otherwise marginal projects more profitable—like a manufacturer offering a coupon that lowers the net price of a major purchase—so they influence valuation, cash flow forecasts and investment decisions.

production tax credits financial

"the company passed on approximately $65 million in production tax credits"

Production tax credits are financial incentives offered to support the development of certain energy projects, such as renewable power sources. They provide a dollar amount for each unit of energy produced, helping to reduce the project's overall costs. For investors, these credits can improve the project's profitability and attractiveness by making renewable energy investments more financially appealing.

base rate financial

"This will avoid the 2% base rate increase outlined in its multiyear"

The base rate is the primary interest rate set by a central authority or used as a benchmark for pricing loans, savings and other financial products. Think of it as the anchor in a floating system: when the base rate moves, borrowing costs, corporate financing and consumer spending tend to shift too, which can change company profits and investor returns across the market.

battery energy storage system technical

"standard 15-year lifespan of its Powerline Battery Energy Storage System."

A battery energy storage system is a device that stores electricity for later use, much like a rechargeable battery for a phone or laptop. It allows energy generated during times of low demand or from renewable sources to be saved and released when needed, helping to balance supply and demand. For investors, it represents a way to support reliable energy flow and capitalize on the increasing demand for flexible, clean power solutions.

kilowatt-hours technical

"reducing residential rates by at least $2.50 per 1,000 kilowatt-hours of"

A kilowatt-hour (kWh) is a unit of energy equal to one kilowatt (1,000 watts) of power used continuously for one hour; it’s the standard way utilities measure and bill electricity. Investors use kWh to compare how much electricity a plant generates, a device consumes, or a storage system can deliver, much like liters tell you how much fuel was used — it directly ties to revenue, costs and the economic value of energy assets.

ST. PETERSBURG, Fla., July 10, 2026 /PRNewswire/ -- Duke Energy Florida is delivering $50 million in customer savings in 2027. The company is implementing an innovative strategy to accelerate the return of tax credits over one year rather than the standard 15-year lifespan of its Powerline Battery Energy Storage System. This will avoid the 2% base rate increase outlined in its multiyear (2025-2027) rate agreement and help keep costs as low as possible for customers.

Our view

"Our customers count on us to continually look for ways to keep our costs in check and help ease their overall financial burden – especially as prices continue to rise in seemingly every aspect of our daily lives," said Melissa Seixas, Duke Energy Florida state president. "By finding a way to return these tax credits faster, we're able to put millions of dollars to work for our customers sooner, while also building the modern energy infrastructure Florida's rapidly growing communities need."

Better reliability, more savings

• Over the next 10 years, Duke Energy Florida plans to build 1.4 gigawatts of battery storage, which will result in more than $500 million in investment tax credits that the company will pass on directly to customers.
• Batteries play an important role in Duke Energy Florida's "all-of-the-above" approach to power generation, storing electricity when demand is low and making it available when customers need it most.
  • The company currently has six sites located throughout the state; the Powerline Battery Energy Storage System in Citrus County will be the seventh site when it is completed next year.
• The more batteries Duke Energy Florida adds to its portfolio, the more useful solar energy sites become, as customers can benefit from the stored energy even when it is cloudy or the sun has gone down.
  • The company is working to establish 12 new solar energy sites by the end of 2028, saving customers a total of approximately $3 billion in displaced fuel costs throughout their service lifetimes.
  • In 2025, the company passed on approximately $65 million in production tax credits from solar energy sites to customers – an amount that will grow as more sites are completed – reducing residential rates by at least $2.50 per 1,000 kilowatt-hours of electricity used.
