Senators Say AI Data Center Firms Aren’t Paying Full Costs

Senators Elizabeth Warren, Chris Van Hollen and Richard Blumenthal released a 27-page report, “Power and Profits: How the AI Data Center Boom Costs Households and Communities,” dated October 2026. Warren’s office lists the press release on 9 October 2026.

The report says seven data center operators, Amazon, Google, Meta, Microsoft, CoreWeave, Digital Realty and Equinix, pay for infrastructure built only for them but resist paying the full cost of shared grid upgrades their projects trigger, and keep seeking tax breaks.

What the Report Covers

The senators sent letters to the seven companies on 15 December 2025. The report says it is based on their written responses and on interviews with Congressional staff; Warren’s release adds discussions with company representatives over the past year.

It sets out three headline findings. Commitments to pay a “fair share” do not cover the full range of costs data centers add for households. The companies seek non-disclosure agreements (NDAs) that limit community input. And they keep seeking tax breaks while offering little quantitative evidence of jobs.

Many interview findings are attributed to unnamed companies (“one hyperscaler,” “another Big Tech company”). Where the report names a company, we name it too.

What the Companies Say They Pay

The report quotes the four Big Tech companies’ letters. Google said it pays “for 100 percent of the electricity we use to power our data centers.” Microsoft said it was committed to paying “for the electricity that we consume.”

Meta said it pays “the full costs for energy used by our data centers,” and Amazon that it pays “the full cost of the electricity we use.”

The report says those “full cost” commitments cover infrastructure built exclusively for a data center, such as a dedicated substation, and do not extend to the full cost of wider network upgrades; the companies said they are willing to pay some, but not all, of those costs. It says the companies broadly opposed “but-for” rules that would make a data center pay the full cost of upgrades that would not otherwise have been needed.

It quotes testimony filed on behalf of Google conceding that much of this infrastructure “would not need to be built but for the growth in the data center industry and are often only serving one or a few customers.”

The Fight Over Tariff Terms

States are writing large load tariffs to stop costs shifting to households. The report says the companies back the idea in general but lobby for softer terms.

On minimum billing demand, the share of contracted power a data center pays for even if it does not use it, the report says consumer advocates support 80 to 90 percent. One Big Tech firm called 90 percent monthly minimum demand charges “insanely high,” and another hyperscaler said it usually views 50 percent as a reasonable threshold.

Another Big Tech company said even a tariff covering all large loads could be discriminatory if its size threshold is high enough, giving the example of a 200 MW threshold.

In Louisiana, the report says an independent consultant to the state utility commission found a power plant purchase was “driven primarily” by Meta’s data center, and estimated the new power would cost an average Entergy Louisiana ratepayer as much as $150 per year.

Non-Disclosure Agreements

The report says all four Big Tech companies routinely request NDAs from utilities, landowners and commercial partners, and in some cases government officials.

It says Microsoft announced in January that it will no longer seek NDAs with local governments but will keep seeking them with state-level agencies and utilities. Amazon announced in early October that it would no longer seek NDAs with the “government agencies” it works with. Google and Meta declined to commit to ending NDAs with local governments.

Meta wrote to Congressional staff that “[m]aintaining confidentiality during project development increases efficiency and speed by enabling all stakeholders to remain focused on the needs of a proposed project.”

Google wrote that “[c]onveying speculative information to the public and/or public officials during [early project diligence] can be more harmful than withholding.”

Tax Breaks and Jobs

The report compares original estimates of state tax breaks with their cost now. It says Texas’s budget board estimated in 2013 that its data center exemption would cost $14.6 million between May 2013 and August 2015. It says the Texas comptroller’s office estimated in April 2026 that the exemptions will cost $3.2 billion over the next two years.

Virginia expected its program to cost about $1.5 million a year when it started in 2008, the report says; in FY2025 it cost more than $1.9 billion. As of April 2026, it says, 28 of the 38 states offering a data center tax exemption had introduced legislation to roll some or all of it back.

On jobs, the report says none of the seven companies were able or willing to give comprehensive figures on full-time jobs. Several estimated roughly one full-time job per megawatt of power demand.

It cites Virginia’s tax department: 1,610 jobs added and $1.9 billion in tax benefits in FY2025, roughly $1.2 million per job. In Illinois, 29 of the 34 data centers that received the state incentive created exactly the 20 jobs it requires.

The report says sales tax exemptions on chips and other equipment are the most valuable breaks. Equinix wrote that taxes “for building materials and building systems” “pale in comparison to the value of the GPUs and other compute related equipment which fill these facilities.” Microsoft confirmed it will keep seeking those exemptions, the report says.

The Senators’ Conclusion

The report concludes that “the data center industry is bulldozing local communities” and is “leaving ordinary citizens stuck with the bills.”

Those are the senators’ words. The release identifies all three as Democrats, and the findings rest on the companies’ answers to their questions.

The Structural Read

The report’s central dispute is grid upgrades. It says the companies broadly opposed “but-for” cost allocation, which would assign them the full cost of upgrades that would not otherwise have been needed.

The report says the tariff terms decide the bill. It says advocates support minimum billing demands of 80 to 90 percent, and one Big Tech firm called 90 percent “insanely high.”

The report treats tax breaks as a second front. It says sales tax exemptions on chips and other equipment are the most valuable, and that Microsoft will keep seeking them.

Three Implications

UTILITIES AND REGULATORS Per the report, minimum billing demand, contract length and exit fees interact, so a high percentage on its own may not cover a utility’s costs.

DATA CENTER OPERATORS Per the report, Microsoft and Amazon have narrowed their NDAs with governments, while Google and Meta declined to commit to ending them with local governments.

STATES Per the report, 28 of the 38 states offering a data center tax exemption had introduced bills to roll some or all of it back as of April 2026.

The Business Engineer Lens

This story maps onto the Business Engineer framework The State of AI Data Centers.

The framework’s thesis: “The structural bottleneck isn’t computing, it’s electrons.”

As we read it, the senators’ report is about the bill for that bottleneck: who pays for the grid upgrades the electrons need, and on what terms.

What Is Not Established

We read the report and Warren’s press release in full. We did not read the companies’ January 2026 letters, which the report cites, or Time’s article on the report. We did not contact the companies or the senators’ offices for comment.

Many findings rest on interviews attributed to unnamed companies, so which company said what is not established beyond the quotes the report attributes by name.

The Bottom Line

The senators’ report draws a line between what the seven operators say they pay, their own electricity and dedicated infrastructure, and what the report says they resist paying: the full cost of shared grid upgrades triggered by their projects. It adds NDAs and tax breaks, citing state figures such as Virginia’s $1.9 billion in FY2025 and roughly $1.2 million per job.
