Utility giant Duke Energy plans to spend industry record $103 billion on growth as data centers boom

Duke Energy is planning to spend an industry-record $103 billion over the next decade to build out power generation and grid infrastructure, making it the single largest capital investment plan among U.S. regulated utilities — and the AI data center boom is the primary catalyst.

The Charlotte-based utility aims to add roughly 20 gigawatts of new generation capacity through a combination of gas-fired plants, solar energy, battery storage, and grid upgrades. That's enough to power approximately 15 million homes — nearly matching the combined population of the Carolinas.

CEO Lynn Sideris describes the moment bluntly: "We're the cool kids now." Amazon, Microsoft, Google, and Meta are all expanding data center operations within Duke's service territory, and the utility's vertically integrated structure — controlling everything from generation to transmission — gives it a speed advantage that hyperscalers increasingly value.

Duke was the first utility to require data centers to rely on backup power during peak demand periods, allowing them to connect to the grid faster rather than waiting for transmission upgrades. The company allows 50 hours of curtailment per year, which Sideris says enables faster onboarding without compromising reliability for residential customers.

But the spending plan comes with friction. North Carolina Governor Josh Stein has publicly clashed with Duke over a proposed 15% rate hike and an additional $800 million in fuel costs, accusing the utility of "shifting the cost of electricity from large industrial users onto the backs of regular people." Sideris counters that data centers pay for their own infrastructure and that rate increases are driven by population growth and climate resilience efforts, including replacing wooden poles with steel and concrete in storm-prone areas.

The $103 billion represents the largest single slice of a $1.4 trillion capital spending push across U.S. investor-owned utilities through 2030, according to the nonprofit PowerLines. Utilities requested a record $31 billion in rate hikes in 2025 alone — more than double the near-record from 2024.

What This Means For You: If you live in Duke's service area — which spans Florida, the Carolinas, Ohio, Kentucky, and Indiana — expect your utility bills to keep rising. Even with data centers paying their own way, the infrastructure needs of population growth and climate hardening will be spread across all ratepayers. For investors, Duke's plan signals that regulated utilities with data center exposure may offer reliable growth, but the political pushback on rates is a risk worth monitoring.
