Recent Company History

Over recent months, DUK news has focused on operations, community support and regulatory restructuring. Storm-preparedness messaging on Mar 15, 2026 and a South Carolina emergency microgrant program on Mar 11, 2026 saw small positive price reactions. Announcements on Mar 10, 2026 about combining Duke Energy Carolinas and Duke Energy Progress, projecting about $2.3 billion in customer savings, aligned with a concurrent $1.3 billion convertible notes offering yet coincided with -1.06% moves. Today’s clean energy program update fits the theme of grid transition and large-customer engagement.

Key Terms

renewable energy, clean energy environmental attributes, environmental attribute tracking, carbon reductions, +1 more

5 terms

renewable energy technical

"strong demand for flexible, streamlined access to renewable energy across the state."

Sources of power that come from naturally replenishing resources—such as sunlight, wind, flowing water, and geothermal heat—rather than fuels that can run out. Investors care because renewable energy can reduce long-term fuel costs, lower regulatory and climate risk, and create growing markets for technology and infrastructure; think of it like putting money into a well that refills itself rather than a one-time fuel tank, offering steadier long-term returns and different risk profiles.

clean energy environmental attributes technical

"through revenue generated from the sale of clean energy environmental attributes (CEEAs)"

Clean energy environmental attributes are the measurable benefits tied to generating electricity from low- or zero-emission sources — for example the right to claim that power came from wind, solar, or other clean sources, often documented as certificates or credits. They matter to investors because they can create additional revenue streams, satisfy regulatory or corporate sustainability requirements, and affect the market value of projects in the same way a brand or warranty can boost the price of a product.

environmental attribute tracking technical

"launched a new Environmental Attribute Tracking tool in partnership with Cleartrace"

Environmental attribute tracking records and verifies the environmental characteristics tied to an activity, product, or unit of energy—for example reductions in greenhouse gas emissions, renewable electricity generation, or water savings—using certificates, registries, or digital records. For investors, it acts like a nutritional label for sustainability: it makes environmental claims measurable and comparable, shaping risk assessments, regulatory exposure, and the value of sustainability-linked assets.

carbon reductions technical

"providing customers with verified tracking of clean energy attributes and associated carbon reductions."

Actions that lower the amount of carbon dioxide and other greenhouse gases a company or activity releases into the atmosphere, achieved by using cleaner energy, improving efficiency, changing processes, or removing carbon from the air. Investors track carbon reductions because they can cut operating costs, reduce exposure to future regulations and fines, and protect reputation—similar to fixing a leaky roof to avoid bigger repair bills and insurance problems down the road.

renewable electricity technical

"a commitment to source 100 percent renewable electricity by 2030"

Electricity generated from naturally replenished sources such as sunlight, wind, flowing water and geothermal heat rather than from burning fossil fuels. Think of it like harvesting a perpetual resource—solar panels catching sunlight or wind turbines spinning in breezes—instead of using up a finite fuel. For investors, renewable electricity matters because it shapes long-term revenue potential, regulatory incentives, capital costs and competitive positioning as economies shift toward cleaner, more reliable power sources.

• Cisco, United States Cold Storage Inc. and Daimler Truck North America among early participants to advance sustainability goals

CHARLOTTE, N.C., March 17, 2026 /PRNewswire/ -- Green Source Advantage Express (GSA Express), Duke Energy's newest clean energy program for large business customers in North Carolina, has surpassed initial enrollment targets, highlighting strong demand for flexible, streamlined access to renewable energy across the state.

The voluntary program allows nonresidential customers to subscribe to capacity from new renewable energy facilities on Duke Energy's grid, helping them match up to 100% of their annual electricity use without securing off‑site generation on their own.

The big picture: Duke Energy developed GSA Express as a more turnkey solution to the company's standard Green Source Advantage plan in response to customer feedback. The program also provides benefits to all Duke Energy retail customers through revenue generated from the sale of clean energy environmental attributes (CEEAs), regardless of whether they participate in the program.

Cisco, United States Cold Storage Inc. and Daimler Truck North America are among the first customers to participate in GSA Express.

By the numbers:

• North Carolina (GSA Express): 177.3 megawatts (MW) subscribed and allocated
• 87.3 MW in Duke Energy Carolinas territory
• 90 MW in Duke Energy Progress territory

Ten percent of additional capacity each calendar year is reserved for new business customers and will be released to large business customers in the fourth quarter of 2026 if not subscribed.

What they're saying:
Meghan Dewey, senior vice president of products, services and pricing solutions for Duke Energy:

"The strong initial response to Green Source Advantage demonstrates how the program meets the real‑world needs of organizations focused on sustainability. By listening to our customers and building on the success of earlier initiatives, we're proud to offer businesses and institutions a simpler, more flexible path to achieving their clean energy goals – empowering them to make meaningful progress toward a smarter energy future."

Evan S. Brown, renewable energy program manager for Cisco:

"Cisco is proud to build on its long-standing energy strategy in North Carolina by participating in Duke Energy's GSA Express program. The program enables access to locally sourced, scalable renewable power that supports our sustainability goals and long-term energy planning. It strengthens the reliability of our Research Triangle Park operations while contributing incremental capacity to the North Carolina energy grid – demonstrating how local partnerships can deliver practical energy solutions."

Jeff Allen, chief operating officer for Daimler Truck North America:

"Partnering with Duke Energy through the GSA Express program is an important step in advancing our sustainability goals and supporting the long-term energy needs of our operations. With a large manufacturing footprint in the area, this program gives us a reliable, scalable way to access clean energy directly from the grid – helping us reduce our emissions footprint while strengthening the resilience of our network. We're proud to be among the first participants and appreciate Duke Energy's commitment to making renewable energy more accessible for companies in North Carolina."

Michael Lynch, senior vice president – sustainable engineering and automation for United States Cold Storage:

"US Cold has set clear climate goals, including a commitment to source 100 percent renewable electricity by 2030 and science-based carbon reduction targets that have been independently validated. Programs like Duke Energy's GSA Express help us advance those commitments in a practical way, alongside investments we're already making onsite, such as the solar installation at our Lumberton facility. Together, these efforts reflect our long-term approach to building a more resilient, sustainable cold chain network."

Threshold requirements: GSA Express is available to nonresidential customers who have an annual peak energy demand of at least 1 MW at a single location or a combined peak demand of at least 5 MW across multiple locations within the same Duke Energy service territory.

Keeping emissions accurate: To support accurate emissions reporting, Duke Energy has also launched a new Environmental Attribute Tracking tool in partnership with Cleartrace, providing customers with verified tracking of clean energy attributes and associated carbon reductions.
