A data center that asks Duke Energy Carolinas for grid upgrades must now commit to paying at least 75% of its planned transmission service for 15 years, even if usage falls short. The Federal Energy Regulatory Commission approved the revised tariff on a 4-1 vote, its first ruling since June orders told grid operators to justify their large-load rules.

Concurring with the order

The Federal Energy Regulatory Commission approved ISO New England's plan to review utility-planned transmission replacement projects. The order, issued October 16, 2026, takes effect January 1, 2027. The review is advisory: ISO New England reports its conclusions to its Planning Advisory Committee but does not decide whether a project proceeds or rule on whether its costs are prudent.

The Federal Energy Regulatory Commission (FERC) on September 22, 2026, rejected Commonwealth Edison's (ComEd) attempt to cancel a transmission security agreement with PowerHouse Hillwood Holding, the developer behind a 1.8-gigawatt, $20-billion data center planned for Joliet, Illinois. The agency declined to take jurisdiction over the contract dispute, saying the U.S. District Court for the Northern District of Illinois is the right venue to resolve it.
