"Tech companies have paid lip service" - US government is asking AI giants why data centers are leading to rising bills

"Tech companies have paid lip service" - US government is asking AI giants why data centers are leading to rising bills News Efosa Udinmwen published AI workloads are driving energy demand at city-scale levels US senators accuse Big Tech of leaving households to pay soaring electricity bills Data centers consume hundreds of megawatts, severely straining regional power grids Private contracts hide which companies are truly paying for power expansion Three U.S. Democratic Senators - Elizabeth Warren, Chris Van Hollen, and Richard Blumenthal - are pressing major technology firms to explain why electricity bills continue to rise in regions packed with large data facilities. Their letters target companies deeply invested in cloud hosting and large-scale artificial intelligence infrastructure. The lawmakers argue that public assurances about absorbing power-related costs do not align with what consumers are experiencing through higher utility rates. Tech firms under fire for power bill failures "Tech companies have paid lip service in support of covering their data centers' energy costs, but their actions have shown the opposite," the trio wrote. "When utilities expand their grid infrastructure, they incorporate the cost of expansion into their utility rates, passing the extra costs onto their customers," they added. On the same day the letters became public, Amazon released a study it had commissioned from Energy and Environmental Economics. The report claims that data center hosting facilities generate enough revenue for utilities to offset the cost of serving them.

In some scenarios, the study suggests surplus revenue could even benefit other ratepayers. However, the analysis relies heavily on projections and modeled outcomes rather than verified historical billing data. There is little disagreement that modern data centers consume a large amount of electricity. Facilities supporting AI workloads often require hundreds of megawatts, with some approaching gigawatt-scale demand. Many regional grids were not built for this level of sustained consumption, forcing utilities to invest billions in new generation, transmission lines, and local upgrades to keep servers online reliably. According to the Senators, utility companies typically recover infrastructure expansion costs by raising rates across their customer base. This means residential and small business users absorb expenses tied to industrial-scale computing projects. Research cited in the letters points to electricity prices potentially rising 8% nationwide by 2030, with far steeper increases in data center-dense states such as Virginia. A recurring concern involves private contracts between utilities and technology companies. Studies referenced by lawmakers indicate that many firms successfully negotiate favorable rates while avoiding direct responsibility for grid upgrades. Confidentiality clauses prevent regulators and the public from clearly seeing how costs are distributed. This lack of transparency makes it difficult to reconcile corporate claims with documented increases in wholesale and retail electricity prices. "Contracts between data centers and utility companies that set electricity prices and other terms are typically confidential," the Senators wrote. "Tech companies searching for a site for a new data center reportedly...
