Maryland's $2 Billion Power Bill for AI Is the Fight Every Grid-Connected Country Will Face
Who pays when AI's energy hunger strains the grid — ordinary households or the tech giants building it?
The $2 Billion Bill Nobody Voted For
Here is what actually happened in Maryland. PJM Interconnection — the regional grid operator coordinating electricity across 13 states, from Illinois to New Jersey, including Washington D.C. — determined that the surge in data centre demand requires major grid upgrades. The cost: approximately $2 billion. That bill is being passed to ratepayers, meaning ordinary electricity customers in Maryland and surrounding states, not the data centre operators driving the demand. Maryland's state government has complained to federal energy regulators, arguing the additional cost breaks what has been called a 'ratepayer protection pledge.' The numbers behind the pressure are significant. Data centres' share of the regional grid is projected to triple between 2024 and 2029. PJM estimates peak energy load will grow by 32 gigawatts from 2024 to 2030 — enough to power at least 24 million homes. Maryland already ranks 13th in the US for residential electricity prices, and between October 2024 and October 2025, average residential prices rose about 18%. Steve Black of the Sugarloaf Alliance put the core objection plainly: 'This isn't a community hospital or a school or even a highway that everybody might use. These facilities exist to make money for a private company, and we are all paying for their capital need.'
This Is Not Just a Maryland Story
The same tension is surfacing wherever data centres are concentrating. In California, Pacific Gas and Electric told regulators that data centre projects seeking power could add about 10 gigawatts of electricity demand over the next decade — roughly four times the generating capacity of the Diablo Canyon nuclear plant. California's Little Hoover Commission released a report warning that AI data centres could spike electricity bills and urging lawmakers to make tech companies, not households, pay for grid upgrades. 'The costs that data centers impose on the electrical grid should be paid by the centers themselves, not by average California families already struggling with high utility bills,' said Pedro Nava, the commission's chair. Since 2020, residential electricity prices across the US have risen more than 36%, from 12.76 cents per kilowatt-hour to 17.44 cents per kilowatt-hour in February 2026, and are forecast to hit 19.01 cents per kilowatt-hour by September 2027. A US Department of Energy report estimated data centres will consume 7% to 12% of the country's electricity by 2028, up from 4.4% in 2023. The pattern — rapid data centre growth, grid strain, rising household bills, public backlash — is not American. It is the template for any grid-connected region that becomes attractive to AI infrastructure investment.
Two Models, One Policy Fight
The core policy question is whether AI infrastructure costs get socialised across all electricity users or internalised by the companies building and using the data centres. Right now, both approaches are being tested simultaneously. Florida signed SB 484 into law on May 7, 2026, requiring any customer with an anticipated monthly peak load of 50 megawatts or more at a single location to cover the full cost of electricity service tied to their project — connections, new transmission, incremental generation, and operating expenses. Public utilities must file compliant tariffs with the Florida Public Service Commission by October 1, 2026. That is the hard-rule approach. The softer approach is voluntary pledges. The White House convened tech companies in early March, announcing a 'Ratepayer Protection Pledge' under which Amazon, Meta, and Google committed to building, buying, or bringing the power required for their projects and covering grid upgrade costs themselves. Anthropic went further in February 2026, committing to pay 100% of grid upgrade costs needed to interconnect its data centres and to procure net-new power generation to match its facilities' needs. Microsoft announced its Community-First AI Infrastructure Initiative in January 2026, with President Brad Smith writing: 'Especially when tech companies are so profitable, we believe that it's both unfair and politically unrealistic for our industry to ask the public to shoulder added electricity costs for AI.' Whether voluntary pledges hold — or whether Florida-style legislation is the only mechanism that actually protects ratepayers — is the central debate now before the US House Energy and Commerce Committee.
