On the exact day DOE Secretary Chris Wright set as the deadline for federal action on how America's data centers connect to the power grid, FERC quietly pushed the decision back by two months. Today, April 30, 2026, was supposed to be the day the Federal Energy Regulatory Commission issued a final rule claiming federal jurisdiction over load interconnection — the first time the federal government would regulate how large electrical loads plug into the interstate transmission system. Instead, FERC chair Laura Swett committed the agency to vote by the end of June 2026, a slip that matters less for the delay itself and more for what it reveals about the collision between the speed demanded by physics and the pace required by law.
The U.S. power system is being bent by a force that was not supposed to exist yet: data centers are now the driver of electricity demand growth. In 2025, data centers accounted for 22% of all new U.S. electricity demand and are on track to triple consumption by 2030 — a growth rate that dwarfs everything else, including industrial electrification and vehicle charging. Solar generation surpassed wind for the first time last summer, and EIA expects another 17% jump in solar output this coming summer, yet transmission additions are failing to keep pace. The interconnection queue has become so congested that new large loads can wait years to connect to the system. Wright saw a bottleneck and reached for the one tool he thought could break it: the power to rewrite the rules of how the grid itself works. In late October 2025, he invoked Section 403 of the Department of Energy Organization Act and directed FERC to open a rulemaking that would assert federal authority over the interconnection of large loads greater than 20 MW — an area that has always been regulated by states and regional grid operators.
The actual proposal is straightforward: FERC will establish a federal standard for how data centers and other large loads connect to the bulk transmission system and require them to pay 100% of the network upgrade costs their projects trigger. The precedent already exists in fragments. PJM established a co-located load order that accelerates interconnection for major customers willing to fund their own grid upgrades. Southwest Power Pool created its High Impact Large Load (HILL) framework, which does something similar. FERC's move is to scale these into a national standard and anchor it in federal law rather than leaving it to the patchwork of regional variations. PJM alone is now proposing to add 14.9 GW of capacity through bilateral contracts and central procurement, a direct response to the demand surge it cannot ignore. The June vote will decide whether FERC has the legal authority to tell states they no longer regulate how large loads connect to transmission, or whether that power remains vested in state commissions and traditional cost-allocation rules.
The two-month slip reveals what FERC actually believes about its legal exposure. Chair Swett framed the delay as a commitment to act in a manner that is "quick, efficient, and legally durable" — the third word doing heavy lifting. If FERC were confident the rule had a clean legal foundation, the extra 60 days would be unnecessary. Instead, the agency is signaling it needs time to build a record that will withstand judicial scrutiny. State regulators and ratepayer advocates have already filed opposing comments. NARUC, the National Association of Regulatory Utility Commissioners, argues that if FERC asserts jurisdiction over load interconnection, it would "interfere with the balancing performed by state regulators in retail rate cases." NASUCA, the National Association of State Utility Consumer Advocates, went further, calling the proposal "patently unreasonable" and warning that an expedited rule would enable cost-shifting that harms traditional retail customers. Neither group denies the demand problem. They deny FERC's right to solve it by overriding state law. The June timeline suggests FERC is taking these arguments seriously enough to spend two months building legal scaffolding that might hold up in the Fourth or Sixth Circuit.
Who wins and who loses is clearer than the legal outcome. Large load customers — Google, Amazon, OpenAI, data center operators, advanced manufacturing facilities — win immediately. A federal rule standardizes the interconnection process and promises faster access to transmission capacity without fighting state regulators or negotiating with multiple regional entities. Grid operators in congested regions, especially MISO, which has seen 43% annual load growth since 2020, win because they get a mechanism to accommodate that demand without re-negotiating the entire regional cost-allocation system. State regulators and utilities that benefit from cost-shifts embedded in traditional retail rates lose. So do residential and small business ratepayers if the rule shifts interconnection costs away from large loads and onto the traditional customer base — though the 100% participant-funded model actually prevents that, which is why the proposed rule tries to protect against cost-shifting and NASUCA's objection rings partly hollow. The real losers, if the rule holds, are smaller industrial loads and regional developers who cannot afford the full interconnection cost and will be priced out of directly accessing transmission. They will have to connect through the distribution system, paying retail rates and waiting in the regional queue. The rule does not solve grid capacity. It rations access to the limited transmission capacity that exists, and it rations it in favor of those who can afford to fund infrastructure.
Here is what is actually happening: FERC is asserting federal jurisdiction over a service that has never been federalized before because the current system cannot move fast enough to accommodate the load growth that is already happening. The data center demand is not theoretical. It is not a forecast. It is happening now. MISO saw 43% annual growth; ERCOT is building new generation as fast as the grid allows and still cannot keep up; the Southeast and Southwest have similar stories. The solar surge adds another complication because solar capacity is intermittent and spreads the problem across more transmission pathways. Wright understood that the only way to unlock large-load access without waiting five years for regional consensus is to assert that this is a federal problem with a federal solution. He is probably right that this is the only way forward. But he is also asking FERC to win a constitutional argument on the fly, which is why Swett pushed the deadline back by two months. The June vote will be the moment FERC either doubles down on federal power or blinks. Betting on FERC blinking would be a mistake. The demand is real, the queue is jammed, and the political pressure to move large loads is immense. The question is not whether FERC acts but whether what it builds will survive the first legal challenge. The extra time is FERC betting that legal durability matters more than hitting an arbitrary deadline.
Watch three things: First, the exact language FERC uses when it votes in June on the scope of federal jurisdiction. If the rule is narrowly tailored to large loads above a specific threshold and explicitly excludes rate-setting authority, it has a better chance in court. If it is broad and reaches toward state retail regulation, the Fourth Circuit will likely strike it down. Second, watch whether any FERC commissioner dissents and on what grounds. Commissioner Rosner's earlier comment that "we need every tool in the toolbox" suggests support for the rule, but a dissent focused on federalism concerns would signal that FERC itself doubts its legal foundation. Third, watch the comment period between now and June. If large load customers, utilities, and state attorneys general file new objections that FERC has not adequately addressed, the June rule may include carve-outs or caveats that reduce its practical impact. The two-month slip was not a concession. It was a signal that FERC is getting serious about winning this fight.
