The NC Utilities Commission rules by mid-November, right after Duke's November 5 earnings. Duke Energy has settled its [long-running large-load tariff fight](https://theinference.org/article/xcel-filed-a-texas-tariff-to-lock-data-centers-into-15-year-contracts-with-exit-fees) in North Carolina, and the four hyperscalers buying most of America's AI power signed it. [Amazon](https://theinference.org/markets/companies/amazon), Google, [Meta](https://theinference.org/markets/companies/meta) and [Microsoft](https://theinference.org/markets/companies/microsoft) joined the NC Public Staff, the Department of Defense and industrial group CIGFUR on [an agreement filed October 6](https://news.duke-energy.com/releases/duke-energy-protects-customers-from-data-center-costs) that makes any new large load of 50 megawatts or more pay a nonrefundable upfront fee for dedicated grid facilities, post deposits and security guarantees for shared upgrades, and take a mandatory High Load Factor rate schedule [1][6]. If approved, it applies to electric service agreements signed after June 1, 2026; contracts signed on or before that date, possibly including Amazon's Rockingham data center, are exempt [1][3]. ## The money moves to the customer at signing For Duke shareholders, the structure converts speculative data-center demand into collateralized revenue. Stranded-asset risk on the buildout shifts to the customer at signing, which underwrites the 5 to 7 percent annual adjusted EPS growth through 2030 that Duke reaffirmed alongside [its November 5 third-quarter date](https://www.ad-hoc-news.de/boerse/news/corporate-news/duke-energy-stock-sets-november-5-earnings-date/70256733) [5]. Duke's North Carolina president Kendal Bowman put it plainly: "data centers will pay upfront for all costs to connect to the grid" [1]. ## The escape hatch and the fuel-charge history Environmental groups see it differently. The Southern Environmental Law Center calls the exit clause too lenient: a departing large customer pays only a small fraction of triggered upgrade costs, and SACE decarbonization director Eddy Moore [describes it as a last-minute escape hatch](https://www.selc.org/press-release/duke-energy-proposal-fails-to-hold-data-centers-accountable-in-large-load-tariff-settlement/) allowing just 25 percent of remaining electricity costs for years [2]. Shared transmission upgrades hit all customers first and are repaid over the contract, and no separate customer class exists to audit what these loads actually cost to serve [2][3]. The credibility backdrop matters. [A North Carolina appellate panel ruled](https://gcn.com/north-carolina-court-found-duke-energy/22279/) Duke's 2024 fuel riders unlawfully included 2022 under-recoveries, about $19.1 million disputed, yet customers will never see a refund because 2025's Senate Bill 266 removed the legal test-period limit [4]. That history is the argument for reading the fine print rather than trusting the shield. ## What decides it The North Carolina Utilities Commission is expected to rule by mid-November [1], days after Duke's November 5 print. The order is the binary: approval as filed locks in the self-collateralizing revenue model; a stiffened version trims it. ## Takeaway The four biggest AI power buyers have co-signed a North Carolina tariff that shifts grid-buildout risk onto data-center customers, but a lenient exit clause and Duke's fuel-charge history leave the real test to the NC Utilities Commission's mid-November order. ## Sources 1.
