Florida Law Forces AI Data Centers to Pay Their Own Power Bills

Treasure Coast homeowners who pay FPL bills have new protection on paper — whether it holds in practice depends on what happens in a regulatory filing room between now and October.

Gov. Ron DeSantis signed SB 484 on Thursday in Lakeland, making Florida the first state in the country to put a binding statute behind a single principle: AI data centers pay for the power grid capacity they consume, and residential ratepayers do not absorb those costs. The Senate passed the bill unanimously in the final hours of the legislative session — a rare moment of bipartisan agreement on Big Tech accountability in Tallahassee, public records show.

The stakes for doing nothing are visible elsewhere. Across the PJM grid stretching from Illinois to North Carolina, ratepayers paid an additional $14.7 billion in capacity charges this year, driven largely by data center demand, according to Carnegie Mellon University researchers. Maryland households are paying $18 more per month. Ohio households are paying $16 more. Northern Virginia — the largest data center market in the country — is on track for a 25% retail rate increase by 2030. Big Tech absorbed none of those costs.

Florida's law designates the Florida Public Service Commission as the enforcement firewall. The PSC must ensure costs are not shifted to consumers. The Office of Program Policy Analysis and Government Accountability is required to study the issue and report findings by July 1, 2027. Local governments retain land use authority over data center siting.

The law's logic is straightforward, said Dr. Mark McNees, director of Social and Sustainable Enterprises at Florida State University's Jim Moran College of Entrepreneurship and managing consultant at The McNees Group: if a hyperscaler triggers $400 million in transmission upgrades, the bill goes to the hyperscaler — not to residential customers three counties over.

SB 484 does not, however, include everything DeSantis sought. The governor pushed for an AI Bill of Rights that would have banned secret nondisclosure agreements allowing data centers to move into Florida communities without public notice. The House stripped that provision after conversations with the pro-AI White House, McNees noted in a published analysis. Companies can still keep expansion plans quiet for up to a year. That fight, along with battles over siting and cumulative grid impact, moves to the 2026 legislative session.

For now, the critical deadline is October 1, when public comments on the PSC's tariff structure are due. The commission must write the rules that give the statute its teeth — or its loopholes. Consumer advocates, the Office of Public Counsel, local governments, utilities, and industry groups are all expected to file. How the PSC defines "data center," what qualifies as cost-causation, and what the tariff actually charges for grid connection will determine whether Treasure Coast ratepayers are genuinely shielded or simply protected on paper.

Texas, Virginia, and Colorado have not passed comparable legislation. Georgia introduced a bill. Michigan built a regulatory framework. Florida, as of Thursday, is the only state with a binding statute — and the model other legislatures are expected to copy when 2027 sessions convene.
