Senator Warren Wants to Tax AI Data Centers. The Electricity Fight Behind That Proposal Is Real.

Senator Elizabeth Warren wants to put a per-kilowatt-hour excise tax on the energy that AI data centers consume — and pair it with a wealth tax on tech billionaires — with the revenue earmarked for workers displaced by automation. The proposal is getting predictable reactions from predictable corners. But before the argument turns entirely into a partisan food fight, it’s worth understanding what the electricity data actually shows.

Warren outlined the plan in a Time magazine op-ed published May 27, calling for a scaled excise tax on data center energy consumption — the bigger the operation, the more they pay — alongside a wealth tax targeting major AI-sector beneficiaries. Revenue would fund universal healthcare, free higher education, and expanded unemployment insurance for workers displaced by automation. American tech companies have eliminated more than 113,000 jobs in 2026, and tech-sector unemployment has climbed to 5.8%, its highest level since the dot-com bust. NBC4 WashingtonNBC4 Washington

The statistic at the center of the political fight is a 267% electricity price increase. Warren’s critics say she’s lying — that the number refers to wholesale nodal power prices near data centers, not what residents pay on their bills. That’s a fair technical point, as far as it goes.

It doesn’t go very far. The original Bloomberg News analysis examined wholesale electricity prices at 25,000 grid nodes and found costs had risen as much as 267% near major data center clusters since 2020. Bloomberg reported explicitly that those wholesale costs are passed on to households and businesses through their utility bills. In the PJM Interconnection — a grid covering 13 states in the Midwest and Northeast, a hotspot for data center construction — an independent monitoring report found data center-driven demand had already pushed up consumer power bills by $13.8 billion. aolAmerican Civil Liberties Union

Retail electricity prices rose 7% in 2025 alone, part of a nearly 40% climb since 2021 that makes this decade the fastest period of electricity price growth on record. Data centers are not the only factor — extreme weather, utility capital spending, and delayed coal plant retirements all play a role. But they are a significant one, particularly in regions with concentrated data center activity. American Civil Liberties Union

Warren’s 267% figure represents the worst-case end of a real range, not a national average. That’s a legitimate criticism of how she’s using the number. The claim that residential customers aren’t feeling data center-driven electricity costs at all, however, is contradicted by the same Bloomberg analysis her critics cite. The data says what it says. It’s a matter of how precisely you characterize it.

The complication is timing. In the short run, at the local level, consumers near data center hubs bear the brunt of regional electricity demand spikes. The long-run economics of more generation coming online tend to favor lower prices — but infrastructure takes years to build, and the gap is real in the meantime. aol

Wisconsin doesn’t have a Virginia-scale data center build-out problem yet. But the broader question Warren is raising — who pays for the energy infrastructure the AI boom requires, and who benefits from it — is going to show up in state rate cases and utility commission proceedings across the country, including here. Worth watching.
