A House subcommittee just took the first formal step toward turning Big Tech’s voluntary “pay your own way” pledge into binding federal law. On June 24, 2026, the Energy and Commerce Subcommittee on Energy marked up the bipartisan Ratepayer Protection Act (H.R. 9340), a bill designed to stop AI data centers from quietly shifting their electricity costs onto household power bills.
The pledge that Microsoft and Anthropic pioneered earlier this year was always a promise. This bill is an attempt to make it a rule.
Definition Box: What is the Ratepayer Protection Act? H.R. 9340 is a bipartisan federal bill, sponsored by Rep. Gabe Evans (R-CO) and Rep. Kathy Castor (D-FL), that would codify the principles behind the White House “Ratepayer Protection Pledge.” It directs state utility regulators to consider forcing the largest power users (any non-residential site drawing 100 megawatts or more) to pay the full incremental cost of the grid upgrades built to serve them, rather than spreading those costs across every customer’s bill.

What Just Happened
The Subcommittee on Energy took up eight electricity and pipeline bills in a single markup on June 24, with the Ratepayer Protection Act as the headline measure. A markup is the first formal step a bill takes toward becoming law, where a committee debates and votes on the text before sending it up the chain.
The significance is less about the procedure and more about the politics. This is the first time Republican leaders have rallied behind concrete legislation to address data-center-driven rate hikes, a notable shift for a party usually wary of anything that looks like cost-shifting onto private companies. Energy and Commerce Chair Brett Guthrie framed it around competition with China and protecting families in the same breath, arguing that families and small businesses should not foot the bill for infrastructure that benefits everyone.
Castor, the Democratic co-sponsor, was blunter about what is driving the bipartisan moment. She attributed Republican engagement to “populist anger” filtering up from constituents. “The public is up in arms,” she said, adding that voters are wary of paying more for electricity regardless of party.
How the Bill Actually Works
The mechanism is technical but blunt. H.R. 9340 amends Section 111(d) of the Public Utility Regulatory Policies Act of 1978, the federal law that sets the framework for how states regulate utilities. The amendment directs state regulatory authorities to consider establishing a “large-load standard” for customers drawing 100 megawatts or more.
That 100-megawatt threshold is the key design choice. It is set high enough to capture hyperscale AI data centers while leaving residential, commercial, and traditional industrial customers untouched. Once a customer crosses that line, the standard would obligate them to absorb the cost of the new generation, transmission, and local infrastructure their facility requires, rather than socializing those costs across the broader rate base.
This targets the more solvable of the two ways data centers push up bills. The first is interconnection: connecting a giant new load often requires expensive substations and transmission lines, and utilities have historically spread those costs across all ratepayers. The bill goes hard at that problem. The second, a tighter overall market lifting prices for everyone, is harder for any single rule to neutralize.

The Backstory: Microsoft and Anthropic Set the Template
The bill did not appear from nowhere. It codifies a voluntary commitment that two companies pioneered months earlier.
In January 2026, Microsoft launched its “Community-First AI Infrastructure” plan, pledging to pay electricity rates high enough to fully cover the costs its data centers create, replenish more water than it uses, create local jobs, and reject local property tax breaks. That made Microsoft the first major hyperscaler to put a comprehensive cost-recovery framework on paper.
A month later, Anthropic followed. In a February 11 blog post, the company behind Claude said AI firms should not leave American ratepayers to pick up the tab, and committed to cover 100% of the grid upgrades needed to interconnect its data centers, paid through higher monthly charges on its own bill.
Then came the formal pledge. On March 4, 2026, seven companies signed the White House Ratepayer Protection Pledge: Amazon, Google, Meta, Microsoft, OpenAI, Oracle, and xAI. Worth noting for accuracy: Anthropic was an early mover on the commitment but was not among the seven White House signatories. The pledge committed the group to a “build, bring, or buy” framework for their own power. We unpacked the strategic logic behind these promises in why Microsoft and Anthropic want to pay more for AI power.
The throughline is a ratchet, from a single company’s voluntary promise to a federal bill in roughly five months.
The Numbers Driving the Anger
The political momentum is built on a few hard figures that voters feel directly.
| Metric | Figure |
|---|---|
| Electricity bill increase near major data center hubs (5 years) | Up to 267% |
| Data centers’ current share of US electricity | 4% to 5% |
| Projected share by 2028 | As high as 12% |
| US AI sector power need over the next several years | At least 50 gigawatts |
| Utility rate-increase requests in the prior year | Roughly $31 billion |
| Americans who oppose data centers in their community | About 7 in 10 |
| State data center bills introduced in 2026 | More than 150 |
The story those numbers tell is simple: a cost that used to be invisible became visible, and it landed on monthly bills during an affordability squeeze. That is the political fuel behind both the federal bill and a wave of state action.
The Skeptic’s Case
A sharp read demands taking the criticism seriously, because the pledge-to-law pipeline has real gaps.
Critics of the original pledge argued it changed little in practice. Harvard’s Ari Peskoe noted that neither the president nor the companies actually control who pays for grid expansions, since utilities and their regulators hold the pen on cost allocation. Consumer advocates made a related point: a voluntary pledge with no enforcement mechanism is a press release, not a protection.
The bill answers part of that critique by moving from voluntary to statutory. But it has its own soft spots. It directs state regulators to “consider” a large-load standard rather than mandating one, leaving discretion at the state level. And the corporate commitments underneath it have scope limits worth remembering: Anthropic’s pledge, for example, applied to facilities it owns in a handful of states, not to the leased capacity that makes up most of its compute. A promise that covers owned infrastructure but not the bulk of leased capacity is a narrower commitment than the headlines suggest.
There is also the legislative reality. A subcommittee markup is the start of a long road, not the finish. The bill must clear the full committee, the House, and the Senate, where grid policy is tangled up in broader permitting fights that have stalled for years.
What It Means for the AI Business Model
This is where the story matters for anyone tracking AI unit economics rather than just the politics.
The pledge, and now the bill, formalizes a structural shift in the data center business model. Power is moving from a back-office line item to a core strategic variable. Hyperscalers and AI labs are being pushed from passive energy consumers into active grid stakeholders that co-invest in generation, deploy on-site power, and absorb delivery risk. Procurement of electrons is becoming a competitive moat alongside chips and models.
The financial impact is real but bounded. Forcing data centers to fund their own grid upgrades raises the per-megawatt cost of capacity in exactly the markets these companies most want to build in. For capital-heavy cloud models like Microsoft’s and Amazon’s, already pouring tens of billions into infrastructure annually, that is a marginal headwind layered on top of states pulling back the tax incentives that used to sweeten the same projects. The combination does not stop the buildout. It reprices it, shifting advantage toward states with reliable power and toward companies willing to fund their own footprint.
For Microsoft and Anthropic specifically, the bill is close to a free brand win. They already pledged to do this voluntarily. Codifying it forces the rest of the field to match a standard they helped set, which neutralizes the cost as a competitive disadvantage and converts an early concession into a moat.
What Is Next
Three things to watch.
First, the federal track. H.R. 9340 now needs to survive the full Energy and Commerce Committee, a House floor vote, and the Senate, where it gets entangled with comprehensive permitting reform. Codifying a voluntary pledge is not the same as a hard rule, and the timeline is long.
Second, the states are not waiting. North Carolina’s House passed its own Ratepayer Protection Act, and Oklahoma moved a Data Center Consumer Ratepayer Protection Act through both chambers. At least 11 states have introduced moratorium bills on new data center construction. The federal bill is one front in a much wider fight.
Third, the regulators. Just before the markup, federal energy regulators at FERC issued orders requiring grid operators to show they can keep utilities and AI companies from shifting data center costs to ordinary customers. The pressure is now coming from Congress, statehouses, and regulators at once.
The Business Model Analyst Take
The headline is not the bill. It is the direction. For the first time, both parties agree that families should not quietly subsidize the AI boom, and that consensus is now hardening from a voluntary promise into proposed law.
For Microsoft and Anthropic, this validates a bet we have flagged before: getting ahead of a cost the market was going to impose anyway, and converting an unavoidable concession into a brand asset and a moat. The smartest move in a cost they could not escape was to volunteer for it first. The bill rewards that timing by forcing everyone else to follow.
For everyone else in the buildout, the message is that the era of socialized data center costs is closing. The per-megawatt math is being rewritten in the markets that matter most, and the companies that priced this in early will look a lot smarter than the ones still waiting for the rules to settle. The bet got repriced in 2026. This bill is the receipt.
Watch the markup votes and the rate filings, not the press releases. That is where you find out who actually meant it.
