With midterm elections approaching, members of Congress are rushing to address voter concerns regarding artificial intelligence data centers and their potential to increase electricity rates. However, determining precisely how much residential utility customers will bear for this infrastructure is a surprisingly difficult task.
This uncertainty has fueled a contentious debate on Capitol Hill, where lawmakers are advancing rival proposals aimed at shielding ratepayers despite the economic complexities involved. Ohio Republican Sen. Jon Husted is pushing the Ratepayer Protection Act, which would encourage state utilities to hold “large-load” customers accountable for cost increases. The legislation passed the House in September with bipartisan support.
Husted faces a fierce reelection battle against Democrat Sherrod Brown, who has targeted Husted’s previous support for data center development in Ohio as a key campaign issue. Meanwhile, Senate Minority Leader Chuck Schumer opposes the Republican bill, arguing its ratepayer protections are merely voluntary. Schumer is instead championing the GRID Savings Act, drafted by New Mexico Democrat Sen. Martin Heinrich, which he claims offers stronger safeguards.
Experts tell NPR that there is no one-size-fits-all answer to how much grid costs residents will absorb, noting that figures vary by state and utility. Nevertheless, they agree that residential customers will ultimately share the financial burden of the AI buildout. One estimate indicates that Maryland customers are paying an additional $168 to $216 annually on their electricity bills due to the data center boom.
Connor Waldoch, co-founder and chief strategy officer at Grid Status, highlighted that local utilities are investing tens to hundreds of millions of dollars in infrastructure, costs that frequently trickle down to customer bills. Tracking these impacts is challenging because the extent to which costs are passed on depends on power-purchasing contracts, retail rates, and regulatory decisions, according to University of Maryland professor Lucy Qiu.
In the PJM regional transmission zone, which covers 13 states and the District of Columbia and supplies power to Northern Virginia—the global hub for data centers—PJM’s Independent Market Monitor estimates that data centers have cost 67 million ratepayers approximately $29 billion over the last two years. Ari Peskoe, director of the Harvard Electricity Law Initiative, noted that these costs are spread across every business and resident with an electricity meter in the region. Several other bills addressing data centers and AI are currently moving through the legislative process.
Are we sure these ‘voluntary’ protections will actually stick, or is this just political theater before the midterms?
It’s staggering to think about that $29 billion passed down to millions of regular people for something they barely use.
