Senators Say Data Centers Shift Grid Costs to Households

Data centers could consume about 20% of U.S. electricity by 2035, up from 5.9% today, according to a Senate report released October 9. The report argues that major data center operators are not covering the full cost of grid upgrades their facilities prompt, leaving some costs to be shared by households and other utility customers.
In Power and Profits: How the AI Data Center Boom Costs Households and Communities, Senators Elizabeth Warren, Chris Van Hollen and Richard Blumenthal detail findings from an inquiry begun in December 2025. Their staff reviewed responses and interviewed representatives of Amazon, Google, Meta, Microsoft, CoreWeave, Digital Realty and Equinix.
Companies draw a line at shared grid upgrades
The senators distinguish between dedicated equipment, such as a substation serving one facility, and broader network improvements that benefit multiple customers but may not have been needed without a data center. They say companies generally commit to paying for infrastructure exclusively serving their sites, but oppose rules requiring them to cover the full cost of shared upgrades triggered by their power demand.
“The companies commit to paying for infrastructure that solely benefits them, but dispute how much they should pay for shared infrastructure that is paid for by all ratepayers but was only built to accommodate the data center,” the senators wrote.
Operators argue that shared upgrades can benefit the wider grid and that costs should therefore be spread among customers. Amazon, in its response to the lawmakers, said it pays for the electricity it uses and invests in generation and transmission infrastructure that benefits ratepayers. The company also cited utility agreements it said protect customers, including long-term commitments and minimum demand charges.
NDAs and tax incentives deepen the dispute
The report says all four large technology companies examined—Amazon, Google, Meta and Microsoft—routinely request nondisclosure agreements from utilities, landowners, commercial partners and, in some cases, public officials. The senators say some companies acknowledged that confidentiality can limit public scrutiny of proposed projects. Meta described confidentiality during project development as a way to increase efficiency and speed, the report says.
The inquiry also focuses on tax incentives. The senators say the seven companies surveyed continue to seek sales-tax exemptions for chips and other equipment, while none provided comprehensive quantitative evidence about permanent job creation at their facilities. The report notes that companies cite construction employment and local tax contributions, but argues those figures do not by themselves show the long-term economic return for communities.
State bills show the scale of the subsidies
The report points to Texas and Virginia as examples of how incentives have grown. Texas’s comptroller estimated that the state’s data center sales-tax exemptions would cost $3.2 billion over two years, while Virginia’s data center tax exemption cost more than $1.9 billion in fiscal 2025, according to figures cited in the report. Those are state-level estimates, not totals for the companies’ incentives nationwide.
The report also describes disagreements over rate rules intended to shield customers. Large-load tariffs can require data centers to pay minimum monthly charges, sign longer contracts or fund infrastructure upfront, but the senators say design details determine whether those protections are sufficient. The inquiry’s central question is whether operators will pay for the grid capacity their projects require—or whether regulators will continue allocating some of those costs across the broader customer base.
