Duke Energy to Issue $10 Billion in Equity to Fund Gas Generation for 'Record Demand'

Duke Energy is embarking on one of the largest infrastructure expansions in the history of the US utility sector, announcing plans to issue $10 billion in common equity between 2027 and 2030 to fund a massive buildout of its power generation fleet. The capital raise is a cornerstone of the Charlotte-based company's $103 billion regulated capital program, designed to meet what executives describe as "record demand" across its six-state service territory.

The primary catalyst for this historic investment is the explosive growth of artificial intelligence and the sprawling data centers required to sustain it. Duke Energy is currently deploying more than $1 billion per month into grid modernization and new generation projects. To manage the immediate financial requirements of this aggressive buildout, the utility announced a $1.75 billion public equity units offering in early August, which will be used to redeem outstanding debentures and manage commercial paper debt.[1]

To support the surging load, Duke Energy plans to construct 15 gigawatts of new generation capacity by 2031. The expansion strategy relies heavily on natural gas, with approximately 7.5 gigawatts of new gas-fired generation planned, paired with 4.5 gigawatts of battery storage. While the company is not currently advancing new nuclear plant construction, it intends to expand and upgrade its existing nuclear fleet to yield an additional 300 megawatts of capacity.

The scale of the data center pipeline driving these investments is unprecedented. More than 5 gigawatts of new data centers are already under construction within Duke's service footprint. The utility has signed 7.8 gigawatts of electric service agreements with major technology companies and expects that figure to nearly double to 15.4 gigawatts by the first half of 2027. Executives noted that these late-stage pipeline conversions could add another $5 billion to $10 billion to the company's five-year capital plan.

However, the sheer size of the $103 billion spending plan has sparked intense scrutiny from consumer advocates, particularly in North Carolina, who have expressed concern that residential ratepayers could be forced to subsidize the infrastructure required by multi-trillion-dollar tech corporations. Advocates have argued that the utility's growth projections might be exaggerated to justify the lucrative capital expenditures.[2]

In response to these concerns, Duke Energy has introduced a "customer protection plus" commitment. The initiative is designed to ensure that large energy users pay the specific costs associated with serving their bespoke facilities. The company is actively developing rate structures that would visibly return the savings generated from these large-load contracts directly to existing residential and commercial customers via their monthly electric bills.

The financial markets have closely monitored how Duke Energy balances this rapid growth with its balance sheet health. Analysts note that the decision to raise $10 billion in equity signals a disciplined approach, prioritizing long-term financial stability over stretching the company's debt capacity. A recent multiyear rate settlement in North Carolina further solidified this balance, reducing earlier proposed rate hikes while inserting refund provisions linked to project timing and federal tax credits.[2]

As the utility sector navigates the transition toward an increasingly electrified and AI-driven economy, Duke Energy's strategy serves as a bellwether. By securing long-term, minimum-take contracts with tech giants and implementing protective tariffs for everyday consumers, the company is attempting to modernize the grid at an unprecedented pace without triggering a ratepayer revolt.[2]
