The Federal Energy Regulatory Commission (FERC), the top US energy regulator, is pressing the nation’s grid operators to overhaul the rules governing how large data centers connect to and draw power from the electric grid, according to a Reuters report dated June 17, 2026. The push targets the regional transmission organizations that manage most of the US high-voltage grid, and lands in the middle of an unprecedented wave of AI-driven electricity demand.
Executive Summary
According to Reuters, FERC is urging grid operators to rewrite their rules for connecting large data center loads — the procedures, studies, and cost arrangements that determine how quickly a gigawatt-scale computing facility can plug into the transmission system and on what terms. The report frames this as a directive from the regulator to the regional grid operators rather than a finished rule, which means the substance will be worked out in filings, stakeholder processes, and likely litigation over the months ahead.
Why it matters: interconnection has become the single biggest bottleneck in the AI infrastructure buildout. Chips can be bought and buildings can be raised in quarters; grid connections for very large loads are quoted in years. Whoever writes the rules for large-load interconnection — how costs are allocated, whether data centers can co-locate with power plants, and what reliability obligations big loads must accept — will effectively set the pace and geography of AI data center construction in the United States. A FERC push to standardize those rules is therefore one of the most consequential regulatory developments the industry has seen this cycle, even before its details are settled.
Interconnection Is Now the Gating Factor for AI Capacity
For most of the grid’s history, the hard problem was connecting new generators; large customer loads arrived gradually and were absorbed through routine utility planning. AI has inverted that. Individual data center campuses now request hundreds of megawatts — in some cases more than a gigawatt, roughly the draw of a mid-sized city — and they request it on construction timelines the traditional load-forecasting process was never designed to handle. Grid operators have responded with a patchwork: some regions created special large-load study tracks, others applied generator-style queue rules to loads, and others negotiated case by case. A federal push to overhaul and presumably harmonize these rules is a recognition that the patchwork itself has become a source of delay and dispute.
For data center developers and their tenants, the near-term effect of any rule rewrite is uncertainty, but the medium-term prize is predictability. A standardized process — with defined study timelines, transparent cost estimates, and clear rules on what a large load must commit to — would let operators of digital infrastructure make siting decisions on engineering and economics rather than on which utility territory offers the friendliest ad hoc deal.
The Fights Underneath: Co-Location, Cost Allocation, and Curtailment
Three unresolved disputes sit beneath any large-load rule overhaul. First, co-location — siting a data center directly beside a power plant and buying its output behind the meter. The arrangement can bypass years of transmission upgrades, but regulators and utilities have questioned whether such configurations pay their fair share for the grid that still backs them up; FERC itself has been wrestling publicly with co-location frameworks since high-profile disputes over data centers sited at nuclear plants in the PJM region. Second, cost allocation: when a multi-hundred-megawatt load triggers new transmission lines or substations, someone pays — the developer, the utility’s general ratepayer base, or some blend. Consumer advocates in several states have argued that ordinary households risk subsidizing AI growth; developers counter that they routinely fund dedicated upgrades. Third, flexibility and curtailment: grid operators increasingly want large loads to accept interruption or demand-response obligations during system stress in exchange for faster connection. Each of these is a genuine economic contest between reasonable positions, and the Reuters report does not indicate which way FERC is leaning on any of them.
Winners, Losers, and the Federal–State Seam
If the overhaul produces faster, standardized large-load interconnection, the clearest winners are hyperscale cloud and AI companies with capital ready to deploy, and the transmission-rich regions able to absorb them. Utilities gain too, if the rules convert speculative or duplicative connection requests — a real problem, since developers often file in multiple territories for the same project — into firm, financially committed ones. The pressure lands on grid operators, which must rewrite tariffs under regulatory deadline while managing record demand growth, and potentially on smaller data center operators, if new rules impose financial-commitment thresholds sized for hyperscalers.
There is also a jurisdictional seam worth watching. FERC governs wholesale markets and the interstate transmission system, but retail electric service and most siting decisions belong to the states, and Texas’s ERCOT grid sits largely outside FERC’s reach altogether. A federal overhaul can standardize how regional operators study and connect big loads, but it cannot by itself resolve state-level fights over who pays or where facilities are built. Buyers should expect a more legible federal process layered over a still-fragmented state landscape, not a single national rulebook.
Background
FERC, created in its modern form in 1977, oversees the interstate transmission system and the wholesale power markets run by regional grid operators. Its interconnection rules historically focused on generators — culminating in a 2023 queue-reform order aimed at the enormous backlog of power plants awaiting connection. Large customer loads, by contrast, were left mostly to individual utilities and states, an arrangement that held until AI demand broke it.
From roughly 2024 onward, gigawatt-scale data center requests, contested co-location deals at nuclear plants in the PJM region, and warnings from grid operators about record demand growth pushed large-load interconnection onto FERC’s docket. The June 2026 push reported by Reuters is the continuation of that arc: the federal regulator moving from case-by-case dispute resolution toward pressing for systematic rules on how the grid absorbs the AI buildout.
