Congress's First Data-Center Cost Bill: House Passes Ratepayer Protection Act 417-3, but Senate Bid Blocked by Heinrich
The clearest legislative movement this week on the compute side of the AI story: the Ratepayer Protection Act — the first bill of its kind taken up by Congress, responding to the data-center backlash ahead of November's midterms — passed the House Wednesday night (Sept 16, 2026) on a 417-3 vote, then stalled in the Senate on Thursday when Sen. Martin Heinrich (D-NM), the top Democrat on the Energy and Natural Resources Committee, blocked a unanimous-consent attempt to pass it without a roll call.
The bill would establish a regulatory framework states could adopt, requiring AI data centers with demand of 100 megawatts or more to cover the costs of new power sources, transmission lines, and other infrastructure rather than passing those costs to consumers. Its sponsor, Sen. John Husted (R-Ohio), 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."
Heinrich's objection was that the framework is voluntary:
"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."
He instead promoted his GRID Savings Act of 2026, which would give FERC rulemaking jurisdiction over facilities demanding 150MW or more and require those data centers to pay increased-demand grid costs. Even some anti-data-center groups opposed the bill as a half-step — Food & Water Watch's Mitch Jones called it "pointless legislation that merely suggests states should act." With the Senate leaving town in two weeks, the bill is all but dead until after the election; Husted (in a tough reelection fight against Sherrod Brown, who has attacked him over data centers) vows to keep pushing.
Why it matters: the frontier's binding constraint is increasingly political, not just electrical — the same midterms that have Trump calling data-center opposition a "SICK conspiracy" (see The Pacing Debate Ships Product: OpenAI Kills GPT-6.1, Nvidia Ships Agent Containment, the Market Starts Pricing the Slowdown) produced a 417-3 House vote to shield ratepayers from data-center costs, and even that consensus bill failed on the "teeth" question. Cost-shifting fights are where AI capex meets voters' utility bills, and Heinrich's FERC counter-proposal is the template the next Congress will argue over.
