3 terms

megawatt-hours technical

"On Jan. 27, energy demand reached a new winter peak of 37,308 megawatt-hours"

A megawatt-hour (MWh) measures electrical energy equal to one million watts of power supplied for one hour — think of it like the number of miles a full tank of fuel will let a car drive, but for electricity. Investors use MWh to compare how much electricity a power plant, solar array or battery can produce or store over time, which directly affects potential revenue, contract value and operating economics.

megawatts technical

"Duke Energy plans to add 19,600 megawatts of diverse new generation 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.

kilowatt-hours technical

"Typical Duke Energy Carolinas residential customers using 1,000 kWh per month"

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.

• Extreme cold in late January and early February required Duke Energy to purchase power from other utilities – to be reflected in customer rates beginning June 1 – reinforcing need for new generation in the Carolinas

CHARLOTTE, N.C., April 15, 2026 /PRNewswire/ -- Duke Energy has filed requests with the North Carolina Utilities Commission (NCUC) related to fuel and purchased power costs incurred during one of the most extreme winter periods in the past decade – costs driven by record customer energy demand resulting from the cold weather and the utility's commitment to keep power available and reliable when it is needed most.

Why it matters

• Extreme cold across North Carolina in late January and early February pushed electricity demand beyond what existing power plants and storage resources alone could supply.
• To ensure homes and businesses stayed warm and powered during prolonged freezing conditions, Duke Energy purchased additional electricity from neighboring utilities at elevated market prices.
• These actions underscore the importance of continued investment in reliable, around-the-clock generation and grid infrastructure as customer demand continues to grow.

Meeting record demand during extreme conditions

During sustained subfreezing temperatures – 10 to 20 degrees below normal – customer energy use surged across the Carolinas. On Jan. 27, energy demand reached a new winter peak of 37,308 megawatt-hours, the highest on record across Duke Energy's Carolinas system.

"When customers need power the most – during extreme cold or heat – reliability is not optional," said Kendal Bowman, Duke Energy's North Carolina president. "Our responsibility is to deliver electricity safely and reliably, even when demand exceeds what our system can supply on its own."

To meet that obligation, Duke Energy relied on regional energy utilities to supplement its own generation, ensuring continuous service during prolonged cold weather.

Supporting reliability for a growing state

North Carolina's strong economic and population growth is driving sustained increases in electricity demand year-round – not only during extreme weather.

• Duke Energy has added approximately 150,000 customers in North Carolina over the past two years, primarily residential and small business customers.
• In 2025 alone, companies announced projects bringing more than 35,000 jobs and $24 billion in investment statewide, much of it tied to energy-intensive manufacturing.

To serve future growth and minimize our reliance upon purchased power from other utilities, Duke Energy plans to add 19,600 megawatts of diverse new generation capacity over the next decade, including new power plants in Person County, N.C., and Anderson County, S.C., along with grid upgrades and energy storage.

"Energy conservation helps manage costs, but long-term reliability requires new infrastructure," Bowman said. "Meeting customer demand – today and in the future – means investing in a system that can perform under the most extreme conditions."

Recovering extraordinary fuel and power costs

The filings request recovery of fuel and purchased power costs, including solar purchases, incurred during the winter period – approximately $500 million for Duke Energy Carolinas and $309 million for Duke Energy Progress. These pass-through costs represent the actual expenses, without markup, necessary to supply power.

To lower the immediate impact on customers, Duke Energy is proposing to spread recovery over 19 months, rather than the typical 12-month period.

If approved:

• Typical Duke Energy Carolinas residential customers using 1,000 kWh per month would see an increase of about $6.90 per month starting June 1.
• Typical Duke Energy Progress residential customers using 1,000 kWh per month would see an increase of about $7.88 per month starting June 1.

Helping customers manage energy costs

Duke Energy recognizes the financial pressures customers face and offers a range of resources to help manage energy use and bills, including:

• Energy efficiency programs
• Budget billing and payment plans
• Financial assistance and agency partnerships
