Duke Energy CEO Warns of Surging Electricity Demand Driven by AI Data Centers

Duke Energy CEO Harry Sideris recently revealed a staggering shift in electricity demand during the Edison Electric Institute’s annual conference in Las Vegas. He indicated that electricity demand is now growing at a rate ten times higher than it did over the past three decades. Historically, American utilities experienced annual load growth of only 0% to 0.5%, allowing for straightforward long-term planning. However, the landscape has dramatically changed, with Sideris projecting a 5% annual load growth driven primarily by the surge in artificial intelligence (AI) data centers.

The rapid expansion of AI technology has led to a significant increase in electricity consumption, as these data centers operate continuously and require vast amounts of power. Sideris, who has been with Duke Energy for 30 years, emphasized the unprecedented nature of this demand surge, stating, "We’ve never seen load growth like we have experienced in the last year."

In response to this escalating demand, Duke Energy has announced an ambitious five-year capital plan amounting to $103 billion. This plan aims to add over 13 gigawatts of new generation capacity by 2030. To put this into perspective, one gigawatt can power approximately 750,000 average American homes. Duke has already secured electric service agreements with data center customers covering 7.6 gigawatts of demand, with an additional 15 gigawatts in the late stages of development. Nearly 5 gigawatts of these projects are currently under construction, with power expected to be drawn starting in the latter half of 2027.

Duke Energy's service areas include rapidly growing states such as North Carolina, South Carolina, Florida, and Indiana, positioning the company favorably to meet the demands of expanding data centers. The relatively lower power prices in the Southeast and Midwest further enhance Duke's appeal to data center operators, as they seek locations with affordable and reliable electricity.

The implications of this shift in electricity demand extend beyond Duke Energy. Goldman Sachs Research predicts that U.S. data center power demand will surge from 31 gigawatts in 2025 to 66 gigawatts by 2027, more than doubling in just two years. By that time, data centers are expected to account for 8.5% of total U.S. peak summer power demand, a significant increase from 4.1% in 2025. The U.S. Department of Energy anticipates that data centers could consume between 6.7% and 12% of all U.S. electricity by 2028.

This shift poses unique challenges for the electricity grid, which is traditionally designed to accommodate predictable demand cycles from residential and commercial customers. Unlike typical electricity consumers, data centers operate at near-full capacity 24/7, creating a constant strain on the grid. Sideris noted the difficulty in planning for this new reality, stating, "Now it seems like every time we plan, we have to re-plan by the time it comes off the printer."

For investors in Duke Energy, the growth trajectory appears promising. The company is targeting a 5% to 7% growth in earnings per share through 2030, with recent financial results exceeding analyst expectations. However, potential risks loom, including rising electricity bills that have sparked political backlash in North Carolina, where the governor has criticized Duke for attempting to pass on $800 million in fuel costs to customers while also pursuing a rate increase.

Sideris defended Duke's pricing strategy, asserting that the company's rates remain below the national average and are increasing at a slower pace than inflation. He highlighted plans to deliver over $5 billion in customer cost savings through tax credit sales and utility mergers in the Carolinas.

For Duke Energy to realize its ambitious growth plans, several factors must align. Construction timelines for data centers need to remain on schedule, regulatory approvals for rate structures must be obtained across multiple states, and gas prices must stabilize, as much of Duke's new capacity will be gas-fired. Despite these challenges, Duke's regulated utility model and consistent dividend history provide a buffer for income-focused investors, while the contracted pipeline of 7.6 gigawatts offers growth potential that few utilities can match.

As Sideris articulated in Las Vegas, the demand for electricity driven by AI is already present, contracts are in place, and construction is underway. The critical question for stakeholders is whether Duke Energy can keep pace with an industry that is evolving faster than any utility has previously encountered.
