NextFin News - Duke Energy CEO Harry Sideris warned on Wednesday that the surge in artificial intelligence is propelling electricity demand growth at ten times the historical pace, a shift that is forcing the utility giant to overhaul its long-term infrastructure strategy. Speaking at a Reuters NEXT Newsmaker event in New York, Sideris characterized the current expansion as a structural break from decades of flat or low-single-digit growth, driven by the massive power requirements of AI data centers and a broader industrial resurgence in the American Southeast.
The Charlotte-based utility, which serves approximately 8.4 million customers across six states, has responded by raising its five-year capital expenditure plan to a record $103 billion. This program, which dwarfs any previous regulated utility filing in the industry, includes the addition of 14 gigawatts of new generation and 4.5 gigawatts of battery storage. Sideris, who took the helm as CEO earlier this year following Lynn Good’s transition to Executive Chair, has maintained a consistently bullish stance on the necessity of aggressive grid expansion to accommodate what he describes as "contracted demand" from tech giants and advanced manufacturers.
While Sideris’s projections align with a broader trend of rising power forecasts across the U.S. utility sector, his specific "ten times" growth metric remains an outlier that reflects the unique concentration of data centers in Duke’s territory, particularly in the Carolinas. This aggressive outlook is not yet a universal consensus among energy economists. Some analysts caution that the actual "load drop"—the amount of power data centers eventually consume—often lags behind the initial capacity requests made to utilities. Skeptics also point to potential efficiency gains in AI hardware and cooling technologies that could eventually temper the steep trajectory of electricity consumption.
The financial burden of this $103 billion expansion has already sparked friction with consumer advocates. In North Carolina, Duke has faced pushback over proposed rate hikes of up to 18%, with critics arguing that residential ratepayers should not bear the primary cost of infrastructure built largely to serve high-margin corporate data centers. Sideris has defended the spending as essential for regional energy reliability, noting that the company plans to issue $10 billion in new equity between 2027 and 2030 to fund the build-out while targeting 5% to 7% annual earnings growth.
The utility’s pivot also includes a renewed focus on nuclear energy, including the potential deployment of small modular reactors (SMRs) at sites like Belews Creek. However, the success of this strategy hinges on navigating a complex regulatory landscape and overcoming the historical cost overruns that have plagued large-scale nuclear projects in the U.S. For now, Duke’s massive capital commitment serves as a high-stakes bet that the AI boom will remain a permanent fixture of the industrial landscape rather than a transient investment cycle.
