Recent Company History

Over the past weeks, Duke Energy has issued a series of Carolinas-focused weather and reliability updates. Starting on Jan. 22, the company warned of multiday outages from Winter Storm Fern and highlighted deployment of over 18,000 workers. Subsequent releases detailed outage counts, restoration progress, and customer assistance tools as freezing conditions persisted. A Jan. 29 update emphasized higher heating bills and conservation programs. Today’s request for voluntary load reduction during another cold stretch continues this pattern of operational communication around extreme weather and grid reliability.

Key Terms

demand response programs, megawatts, energy storage

3 terms

demand response programs technical

"working with large commercial and industrial customers who have demand response programs."

Demand response programs pay electricity users or adjust their consumption automatically to reduce power use during peak periods, helping balance supply and demand and avoid blackouts. For investors, these programs can lower operating costs for large users, create revenue streams for technology and service providers, and change utilities’ capital needs—think of it like traffic control that eases rush-hour congestion to keep the system running smoothly.

megawatts technical

"collectively own 55,100 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.

energy storage technical

"including natural gas, nuclear, renewables and energy storage."

Energy storage involves capturing and holding excess energy produced during periods of low demand for later use when demand is higher. Think of it like a rechargeable battery that saves power for when it’s needed most. For investors, energy storage is important because it helps balance supply and demand, making energy systems more reliable and efficient, which can influence the value of energy-related assets and technologies.

CHARLOTTE, N.C., Feb. 1, 2026 /PRNewswire/ -- Extremely cold temperatures – 10 to 20 degrees below normal – are driving unusually high energy demand across the East Coast, including the Carolinas. Duke Energy is asking all Carolinas customers to voluntarily reduce their energy use from 4-10 a.m. on Monday, Feb. 2, to help lessen the energy demand on the grid and reduce the potential of temporary power outages.

Customers can help ease strain on the grid by taking the following steps:

• Reduce your thermostat to the lowest comfortable setting.
• Avoid using major appliances such as washing machines, clothes dryers and dishwashers between 4 a.m. and 10 a.m.

• Electric vehicle owners: Charge midday, when demand is lower.

"We know it's inconvenient to reduce electric use, but it makes a real difference," said Gerald Wilson, Duke Energy vice president of grid operations. "We are taking every step to meet our customers energy needs, including maximizing our generation and purchasing power and working with large commercial and industrial customers who have demand response programs. We appreciate our customers' cooperation, patience and understanding as we work to maintain reliable service across the Carolinas."
