AI data centers are straining power grids — and towns are pushing back
From Kentucky to North Carolina to Italy, communities are fighting over who builds AI data centers, who powers them, and who picks up the electric bill.
What happened: This month brought a wave of AI data center friction. In Kentucky, state Senate leader Robert Stivers is pushing data centers as an economic opportunity while London, KY passed a two-year moratorium over infrastructure worries. In North Carolina, protesters challenged Duke Energy's proposed rate hikes and an Amazon campus's 645 diesel generators. In Italy, Colleferro's council approved a 150MW AI data center after two years of negotiation. Meanwhile, Dell'Oro Group projects global data center capital spending will top $3 trillion by 2030, with power availability now the biggest bottleneck to building any of it.
Why it matters: Data centers are quietly becoming one of the biggest new forces on local power bills and land use. North Carolina's own task force found data centers are 30% of Duke Energy's project pipeline but 80% of its projected demand growth through 2030. Duke posted $4.9 billion in profit in 2025 while asking regulators to let it raise average residential bills by about 17% over two years. Attorney General Jeff Jackson says the company understated how much bills would actually rise. Ordinary ratepayers, not just data center customers, may be funding the buildout.
How it works, plainly: Utilities size the grid for the worst day of the year, not the average one — Duke researchers say the U.S. grid runs at only 53% of capacity on a typical day. A 2025 Duke University analysis argues data centers could plug in faster, and delay costly new plants and power lines by roughly five years, if they agree to briefly cut power use during the handful of peak-demand hours annually. Other options include on-site gas generators (faster, but fossil-fuel-heavy) or paying for home solar and batteries that act as a shared 'virtual power plant' to ease strain on the grid.
The rollout: There's no single national approach. Kentucky lawmakers want statewide rules that make developers 'pay their own way,' while individual towns like London set their own moratoriums, extendable through 2028. North Carolina regulators are still weighing Amazon and Duke's air permits after a public comment period closed July 31. In Italy, Colleferro's project still needs national government sign-off before construction starts in 2027. With Dell'Oro projecting 200+ gigawatts of new global data center power demand by 2030, these local fights over who decides and who pays are likely to multiply, not resolve, in the near term.
