The disclosure and our analysis
Evidence dates
Evidence: Duke Energy press release dated October 7, 2026. Additional terms reported by WSOC-TV on October 8, 2026 and Blue Ridge Public Radio on October 7, 2026. We did not review the settlement filing itself.
What Duke disclosed
**Parties:** Duke Energy Carolinas and Duke Energy Progress settled with the North Carolina Public Staff, the agency representing utility customers. Amazon, Google, Meta, Microsoft, the Carolina Industrial Group for Fair Utility Rates and the U.S. Department of Defense are also parties. [Source 1]
**Who it covers:** Duke previously required large loads of 100 MW or more to accept contract terms protecting other customers. If approved, the new terms would apply to all large load customers of 50 MW or more with an 80% load factor that sign an electric service agreement in North Carolina after June 1, 2026. Duke says agreements signed before June 1 already contain similar protections. [Source 1]
**Terms Duke lists:** [Source 1]
A nonrefundable upfront payment for grid facilities serving only that customer, such as a substation.
Upfront deposits and security guarantees for grid upgrades that serve all customers, such as transmission lines.
Service under a High Load Factor rate schedule, a separate rate for large loads.
**Status:** The settlement needs approval from the North Carolina Utilities Commission, and Duke expects a decision by mid-November. Duke Energy Carolinas and Duke Energy Progress are set to combine into one utility on January 1, 2027. [Source 1]
What others report
WSOC-TV reports that the rules set a minimum billing requirement of 75%, so a 50 MW data center would pay as if it used at least 38 MW each month, and that customers would pay penalties for canceling a project or closing early. Blue Ridge Public Radio reports that other transmission upgrade costs would initially be spread across all customers and repaid over the data center's contract, that an early exit would cost only a fraction of the remaining balance, and that some cost allocation questions are left to the next rate case. These terms are not in Duke's release, and we have not verified them in the filing. [Source 2] [Source 3]
Buyer analysis
This is our analysis.
**The threshold drop is the headline for mid-size buyers.** Moving from 100 MW to 50 MW with an 80% load factor pulls many single building colocation and enterprise AI deployments into the same upfront payment and security regime as hyperscale campuses. Operators planning North Carolina sites in that range should budget for upfront dedicated facility payments and collateral before an electric service agreement is signed.
**The hyperscalers signed on.** Amazon, Google, Meta and Microsoft are parties, which makes the terms less likely to be fought at the Commission. That raises the odds that these terms, or something close, become the baseline.
**Grandfathering matters.** Agreements signed before June 1, 2026 sit outside the new terms. Sites with an existing electric service agreement may carry different cost and security obligations than new ones, which is worth asking about in any site comparison.
**It is proposed, not in effect.** Until the Commission rules, treat the terms as a settlement position.
