Senators say AI data center firms resist paying the full cost of the grid they are building

Three Democratic senators released a 27-page report on October 9, 2026, saying the biggest data center operators are not paying the full cost of the grid they are building and are still seeking tax breaks and secrecy agreements. The report, "Power and Profits: How the AI Data Center Boom Costs Households and Communities," comes from Sens. Elizabeth Warren, Chris Van Hollen and Richard Blumenthal. It rests on what Amazon, Google, Meta, Microsoft, CoreWeave, Digital Realty and Equinix told them in answer to letters sent on December 15, 2025. These are the senators' findings, drawn from company responses and staff interviews, and many of the interview findings are not attributed to named companies.

The core claim: "fair share" has a gap in it

The companies say publicly that they pay the energy costs of serving their facilities. The report says that promise covers infrastructure built only for them, not the wider system upgrades their load triggers. In its words, the companies "broadly opposed" "but-for" cost allocation standards, under which a data center would pay the full cost of any upgrade that would not have been needed without it.

The report quotes Google testimony conceding that much of this infrastructure "would not need to be built but for the growth in the data center industry." It also cites a Pennsylvania consumer advocate who argued that if a large load is the but-for cause of network improvements, it "should be responsible [for] 100% of the cost of those upgrades."

The numbers the senators assemble from other sources:

• Data centers account for around 20% of US energy use in 2035, up from 5.9% today, by the report's cited estimate.
• In the 13 mid-Atlantic states served by PJM Interconnection, data center demand will add an estimated $6.3 billion in charges for ratepayers in 2028 and 2029.
• Maryland ratepayers will pay $1.6 billion for transmission over the next decade that will "mainly serve out-of-state data centers."
• Investor-owned utilities requested $18 billion in rate increases in 2025, which the report calls the highest in decades.

The Louisiana example

The report's clearest case is Meta's $50 billion Louisiana data center. Entergy Louisiana's chief executive said the arrangement "is structured so that Meta covers its own costs." In a case before the state utility commission, an independent consultant found that a new power plant purchase is "driven primarily" by the Meta data center, and estimated it could cost an average Entergy Louisiana ratepayer as much as $150 per year. Entergy argued that "[n]o single customer is driving this acquisition," and Meta called the consultant's report "inaccurate speculation."

That dispute is the whole report in miniature. Everyone agrees the customer pays for its own substation. The fight is over who pays when a new plant is bought because of that customer.

Secrecy and tax breaks

On nondisclosure agreements, the report says all four hyperscalers routinely request them from utilities, landowners, partners and sometimes government officials, and that several acknowledged the goal of NDAs with public officials is to limit public scrutiny. Meta told the senators that "Maintaining confidentiality during project development increases efficiency and speed." Microsoft says it will stop seeking NDAs with local governments but, the report says, will continue with state-level agencies; Amazon announced in early October that it would no longer seek them with government agencies, though the report says it is unclear how far that goes. Google and Meta did not commit to ending NDAs with local governments.

On tax breaks, the report says none of the seven companies could or would offer comprehensive quantitative evidence of full-time job creation. It points to Illinois, where 29 of 34 data centers receiving a tax incentive created exactly the 20 jobs required to qualify, and to a Meta facility operated through a shell company that reportedly created 50 jobs and received $50 million in tax benefits, an average of $1,000,000 per job.

What it does not show

A fair reading needs three caveats. First, this is an oversight report by three senators from one party, built on company answers they requested, and we did not find a point-by-point company response. Second, several figures are cited from outside studies and utility filings rather than produced by the senators. Third, the report documents opposition to a cost-allocation rule and does not prove any specific household is overcharged today; that is a case-by-case matter before each state commission.

The companies' own words are in the report, and they are the strongest evidence. Amazon told the senators it makes "substantial investments in new generation and transmission infrastructure that benefit all ratepayers." That can be true and still leave the gap the report describes. A new transmission line can help many customers and still exist only because one customer needed it.

Where this fits in the race

Power is the physical limit on the compute race. We have covered who pays for the AI data center boom and the grid interconnection bottleneck. The new report moves the argument from megawatts to bills, and from bills to law, since states are the ones that set tariffs and tax rules. The report notes that as of April 2026 a majority of states offer data center tax incentives, and that several have moved to repeal or reduce them.

Our take

The report does not decide who is right, but it gives regulators a checklist. If you sit on a state utility commission, ask whether the large-load tariff applies a but-for standard, what minimum billing demand it sets, and whether the NDA covers the commission. If you are a lab or a cloud company, the likeliest next fight is not a federal ban but a rate case in a state where your next campus is going. We would watch the Louisiana decision and any state that adopts a but-for rule. The cost of the race has to land on someone, and this report names the three places it might land: ratepayers, taxpayers and the neighbors who were never told.
