A single Democratic senator torpedoed a bill to stop AI data centers from driving up electricity bills for ordinary Americans, one day after the House passed it 417-3.
Sen. Martin Heinrich of New Mexico, the top Democrat on the Senate Energy and Natural Resources Committee, objected Thursday to a unanimous consent request that would have sent the Ratepayer Protection Act to the president's desk without a roll call vote. The move effectively killed the measure with the Senate set to leave town in two weeks and midterm elections approaching in November.
The bill, introduced in July by Sen. Jon Husted, R-Ohio, would have created a voluntary framework for states to require large AI data centers, those drawing 100 megawatts or more, to cover the costs of building new power sources, transmission lines, and other infrastructure instead of passing those expenses to consumers. The House cleared it Wednesday night with near-unanimous support; only three members voted no.
Husted brought the bill to the Senate floor Thursday and asked for unanimous consent, a procedural shortcut that lets the chamber pass legislation quickly, so long as no senator objects. Heinrich objected.
His argument: the bill lacks teeth. Speaking from the floor, Heinrich said:
"It's not enough to tell states to consider making data centers pay for grid updates. Rather than voluntary pledges or suggestions to states, Congress needs to pass real legislation with real teeth."
Heinrich instead promoted his own proposal, the GRID Savings Act of 2026. That bill would hand the Federal Energy Regulatory Commission, the federal agency that oversees interstate energy markets, rulemaking authority over facilities demanding 150 megawatts or more. It would require those data centers to pay for any costs tied to increased demand on the grid.
Sen. Bernie Moreno, R-Ohio, objected to Heinrich's counter-request and fired back on the floor:
"All we had to do was not have an objection from a Democrat senator. That bill would become law today and taxpayers all over America, electricity users all over this country would have seen immediate relief."
The stakes behind the bill are not abstract. Husted laid out the scale of the coming buildout on the Senate floor:
"America's expected to build the equivalent of 1,000 major data centers during the next five years... with more than 2,000 projects currently being proposed or tracked. And we need to protect American ratepayers from footing the bill. The clock is ticking, and we have no time for delay."
Those numbers frame the urgency. Every megawatt a new data center draws from the grid is a megawatt that existing power infrastructure must accommodate, or that new infrastructure must supply. When utilities build out capacity for a single massive customer, the cost traditionally gets spread across every household and small business on the same grid. The Ratepayer Protection Act was designed to shift that burden back onto the data center developers themselves.
Heinrich's objection did not dispute the problem. He disputed the remedy. His GRID Savings Act sets a higher threshold, 150 megawatts instead of 100, but replaces the voluntary state framework with a federal mandate enforced by FERC. The difference is not trivial: one approach trusts states to act; the other compels a federal agency to write binding rules.
Heinrich was not entirely alone in opposing the measure. In the House, the three "no" votes came from progressive Democrats: Reps. Summer Lee of Pennsylvania, Delia Ramirez of Illinois, and Rashida Tlaib of Michigan. Environmental and anti-data center groups also lined up against it.
Mitch Jones, managing director of policy and litigation at Food & Water Watch, issued a statement Monday calling the bill inadequate:
"If Congress truly intends to take the AI data center crisis seriously, it must reject this pointless legislation that merely suggests states should act."
The pattern is familiar. A bipartisan bill clears the House with overwhelming support. It arrives in the Senate. And a faction on the left blocks it, not because they oppose the goal, but because they want a bigger, more centralized version of the same policy. The result is that nothing passes and ratepayers get no protection at all.
Husted faces a tough reelection battle in Ohio. The Cook Political Report with Amy Walter rates his race a toss-up. His Democratic opponent, former Sen. Sherrod Brown, has accused Husted of helping bring data centers to Ohio during his time as lieutenant governor, an attack that tries to pin the very problem the Ratepayer Protection Act was written to solve on the man who wrote it.
Husted said Thursday he would continue working toward passage despite the setback. But the math is bleak. With the Senate scheduled to recess in two weeks and the election looming, the bill's failure on the floor all but guarantees it will not advance out of Congress before voters go to the polls.
That leaves ratepayers exactly where they started: exposed to rising utility costs driven by a data center buildout that shows no sign of slowing down.
Heinrich's objection followed a script that has stalled bipartisan legislation for years. A bill with 417 House votes is not a partisan wish list. It is as close to consensus as Congress gets. Yet one senator, armed with a procedural veto and a competing proposal that has not cleared either chamber, was enough to stop it.
Heinrich says he wants "real teeth." What he delivered Thursday was no teeth at all, just a dead bill and a talking point. His alternative, the GRID Savings Act, remains a Senate bill with no House companion and no floor vote scheduled. If it never passes, ratepayers will not remember the distinction between a voluntary framework and a federal mandate. They will remember that their electric bills went up and Congress did nothing.
Husted's bill was not perfect. Voluntary frameworks rarely are. But it had something Heinrich's proposal does not: 417 votes in the House and a clear path to the president's desk. Heinrich traded a bipartisan win for a press release.
When the power bill arrives, consumers will not care which Democrat thought the fix wasn't ambitious enough, they will care that nobody fixed it.
