Duke Energy’s renewable-energy efforts look different depending on whether you are asking about company climate goals, utility planning in the Carolinas, or a customer program. Its 2019 companywide announcement set emissions goals and a renewable-portfolio target for 2025; its 2025 Carolinas plan sets later solar and battery-storage targets; and its customer programs offer some businesses a way to support or procure renewable energy. A proposed residential solar program is not established here as currently approved or open for enrollment.
What are Duke Energy’s renewable-energy commitments?
Duke Energy’s September 17, 2019 climate-strategy announcement set a goal of net-zero carbon emissions from electric generation by 2050, with an interim goal of reducing carbon dioxide emissions at least 50% by 2030 compared with 2005 levels. These are company-stated emissions goals, not a measure of renewable electricity supplied to each customer.
The same 2019 announcement said Duke planned to at least double its solar, wind and other renewables portfolio by 2025. That target year has passed. The available information does not establish whether Duke achieved the doubling, so it should be treated as a historical target rather than a current future initiative.
These commitments are not interchangeable: the emissions goals concern carbon dioxide from electric generation, while the 2025 statement concerned the size of the renewables portfolio. The company said implementation would vary by state and depend on collaboration with regulators, customers and other stakeholders.

What does Duke’s current Carolinas plan call for?
Duke’s 2025 Carolinas Resource Plan, filed in October 2025, sets planning targets of 4,000 megawatts (MW) of solar and 5,600 MW of battery storage by 2034. These figures apply to the Carolinas plan, not to Duke Energy’s entire service territory or companywide portfolio. They are planning targets; regulatory decisions, changing economics and later filings can affect them.
Wind and pumped storage in the plan
Under the assumptions in that plan, Duke described wind as not economically viable for customers through 2040 and said it would reassess the resource in the next plan update. That is the plan’s assessment, not a general conclusion about wind economics in other places or under different assumptions.
Rank #2
The plan also defers the in-service target for a second pumped-storage power block at Bad Creek from 2034 to 2040, describing limited near-term development. Pumped storage can store energy by moving water between reservoirs, but it is a storage resource rather than a renewable generation target.
Which Duke renewable-energy programs can customers use?
The programs described here are for business customers, and their availability and structure vary by state. They are distinct from the utility’s resource plan: a business subscription is not the same thing as Duke building a planned utility-scale resource.

| Program | Who and where | What the program offers | Reported status |
|---|---|---|---|
| Green Source Advantage Express | Nonresidential customers in North Carolina | Voluntary subscription to capacity from new renewable-energy facilities on Duke’s grid; customers may match up to 100% of annual electricity use without independently securing off-site generation. The March 17, 2026 announcement does not state price, contract duration or full contract terms. | Duke reported 177.3 MW subscribed and allocated as of March 17, 2026: 87.3 MW in Duke Energy Carolinas territory and 90 MW in Duke Energy Progress territory. Availability may have changed since that report. |
| Green Source Advantage | Participating large businesses in South Carolina | Supports new renewable projects on Duke’s grid. Duke says participating customers receive renewable energy certificates and bill credits. The cited announcement does not state program price, contract duration or complete terms. | Ebbie Solar, a 10 MW project in Marion, entered operational service on February 3, 2026. Duke identified it as the first South Carolina project under the updated program. |
Green Source Advantage Express in North Carolina
Duke’s March 17, 2026 release described Express as a voluntary, turnkey option for nonresidential customers. It reported that 10% of additional capacity each calendar year is reserved for new business customers. The remaining capacity was scheduled to be released in Q4 2026 if it had not been subscribed. Because the capacity report and release schedule are time-sensitive, businesses should confirm current availability and terms directly with Duke before making plans.
The program can help a business match its annual electricity use to subscribed renewable capacity, but the announcement does not establish that the customer receives electricity directly from a particular project at every moment. Nor does the available information support a cost comparison with the South Carolina program.
Green Source Advantage in South Carolina
Duke says the updated South Carolina program supports new renewable projects on its grid and provides participating large businesses with renewable energy certificates and bill credits. Ebbie Solar’s entry into service is a project milestone, not a statement that every customer can enroll or that capacity remains available. Confirm current eligibility, availability and contract details with Duke.
Can residential customers get solar through Duke without rooftop panels?
Duke’s news index surfaced a January 2025 announcement about a voluntary solar program proposed for North Carolina and South Carolina. It was framed as a way for residential customers to receive solar benefits without installing and maintaining rooftop panels. That announcement alone does not establish current regulatory approval, enrollment availability or program terms. Do not assume the program is open: check the relevant Duke Energy state utility page and applicable regulator information for a current approval and enrollment notice.

If you represent a business considering a program, compare the details that determine what participation actually means, rather than relying on a headline capacity figure:
- Territory and eligibility: Confirm that the customer and facility are in the eligible service area and meet the program’s customer requirements.
- What is matched or received: Establish whether participation is a subscription to capacity, a match to annual electricity use, or includes renewable energy certificates and bill credits.
- Maximum share of usage: For North Carolina Green Source Advantage Express, Duke’s announcement says customers may match up to 100% of annual electricity use. Do not assume the same limit applies to another program.
- Project and capacity timing: Ask which projects or capacity are available and when subscriptions or allocations take effect.
- Price and contract obligations: Request the current price, contract duration, exit provisions and billing mechanics. The cited program announcements do not supply enough detail to compare these terms.
For residential customers, the first question is different: whether a proposed program has since received approval and is actually accepting participants in the customer’s state. A proposal is not an enrollment offer.
What is—and is not—established about Duke’s future renewable plans?
The clearest dated forward-looking figures in the available information are the 2025 Carolinas plan’s 2034 targets for solar and battery storage. They should be described as Carolinas planning targets, not guaranteed construction outcomes or companywide goals. The historical 2025 renewables-doubling target cannot be described as a future plan, and the available information does not establish its result.
Likewise, the 2019 net-zero and 2030 emissions goals are dated company statements. The information here does not establish whether Duke has since revised or supplemented those companywide goals. For current decisions, consult Duke’s latest corporate disclosures, state resource-plan filings and program terms.
