Data center infrastructure

Who pays for AI's power bill? Regulators just weighed in

Last updated: 26 June 2026

On 18 June 2026, federal energy regulators told the six grid operators that cover most of the United States to justify or rewrite the rules for how data centers and other very large electricity users connect to the grid. The orders set tight deadlines, 60 days and 30 days, but they do not approve any connection or grant any project a shortcut. This is pressure on a process, not a finished rule.

What FERC actually did

The technical version. FERC issued tailored show cause orders under Section 206 of the Federal Power Act to all six jurisdictional RTOs and ISOs, directing each to justify why its open access transmission tariff remains just and reasonable for large loads or to file reforms, with a 60 day window for tariffs and a 30 day window for resource adequacy reporting. The Commission declined a generic rulemaking in favor of region-specific orders, a move that recognizes differing market designs and hardens the action against jurisdictional challenge.

In plain terms. FERC is the federal referee for the high voltage power grid. It did not approve a single data center or move anyone to the front of a line. What it did was put every regional grid operator on notice: either prove your current connection rules still make sense for these enormous new users, or change them, and do it on a clock. Think of it as a regulator telling six traffic authorities to rewrite the on-ramp rules, not waving any one truck through.

Why this was needed

The technical version. Interconnection queues were built for predictable, incremental load, not gigawatt-scale campuses arriving in clusters. The mismatch is structural: a campus can be built in two to three years while transmission and generation take far longer to plan and energize, and concentrated large loads now effectively dictate where the grid must expand, a reversal of the traditional plan-then-build sequence.

In plain terms. Building an AI data center is the fast part. Hooking it up to enough electricity is the slow part, and the waiting line to connect has become a years long jam. One large AI campus can draw as much power as a small city, and a lot of the grid is decades old and was never designed for that. The pressure shows up on the bill. By one Bloomberg analysis, data centers reached close to 40% of Virginia's electricity use, and prices in heavy data center areas climbed sharply claim. PJM, the largest US grid operator, has warned it could fall several gigawatts short of its reliability target in 2027 claim.

Who pays, and the five reform areas

The technical version. The orders identify five reform categories: faster application and study processes, including alternative transmission technologies; cost transparency and protection against cost shifting; accommodation of colocation and behind-the-meter generation; new services for flexible large loads; and study processes for generation serving electrically proximate loads. The underlying DOE framework proposed assigning 100% of network upgrade costs to the interconnecting load for facilities of 20 MW or greater, though that is DOE's proposal, not a finalized FERC mandate.

In plain terms. The central fight is who pays for the wires and substations a data center needs. FERC's direction leans clearly toward making the data center foot that bill rather than spreading it onto households, and toward forcing operators to publish how those costs are calculated. The 100% figure that some coverage cites comes from the Energy Department's proposed framework, not a rule FERC has locked in, so treat it as the destination, not the arrival projection. The orders also bless a workaround that is already spreading: data centers pairing with their own on-site power, often natural gas, so they can sidestep the queue entirely.

What happens next

The technical version. Compliance filings and resource adequacy reports are due on the 30 and 60 day timelines, after which FERC can accept the filings or impose remedies. The Commission left the generic docket open to reach non-RTO utilities later, and signaled it will dictate solutions if operators fall short.

In plain terms. This is a starting gun, not a finish line. By mid August the grid operators have to answer, and any real rule changes come after that projection. The bigger signal is what it says about the AI race: the bottleneck is no longer chips, it is electricity, and Washington just treated that as a national priority rather than a problem the market would sort out on its own.
