COLUMBUS, Ohio — A high-stakes legal battle reached the Ohio Supreme Court this week that could determine whether everyday residents or trillion-dollar tech giants will pay for the massive electrical upgrades sweeping across Central Ohio.
The Office of the Ohio Consumers’ Counsel (OCC) filed a critical merit brief on Tuesday, March 24, 2026, defending a state regulatory decision that forces data centers to foot the bill for the infrastructure they require. At the heart of the case (Supreme Court Case No. 2025-1458) is a simple but expensive question: When a utility builds new power lines to serve a “power-hungry” data center, who pays the bill?
The “Data Center Tax” Debate
In 2025, the Public Utilities Commission of Ohio (PUCO) approved a new “tariff” for AEP Ohio. This rule requires large data centers to pay for at least 85% of the energy they reserve—even if they don’t use it. This ensures that the costs of building new transmission lines are covered by the tech companies themselves, rather than being shifted onto residential monthly bills.
However, a coalition of industrial consumers and tech giants—including Amazon, Google, and Microsoft—has appealed that decision to the Supreme Court. They argue the rules are discriminatory and could stifle economic growth in the state.
“Cost Causers Should Pay”
Maureen Willis, the Ohio Consumers’ Counsel, didn’t mince words in the filing.
“Cost causers should pay their fair share,” Willis stated. “Ohio residential consumers should not be stuck carrying the load.”
The OCC argues that with data center electricity demand in Central Ohio projected to double in the coming years, failing to enforce these rules would lead to a massive “hidden tax” on families. Without this protection, residential customers could see their rates spike to fund the specialized, high-voltage infrastructure that only data centers use.
Why It Matters for You
Central Ohio has become one of the largest data center hubs in the world. While these facilities bring tax revenue and prestige, they use an unprecedented amount of electricity.
- The Scale: A single large data center can consume as much power as an entire city.
- The Risk: If a data center project is canceled or uses less power than promised after the lines are built, the utility (AEP) still has to recover those construction costs. Under the current PUCO ruling, the data center pays an exit fee. Under the tech giants’ preferred plan, that “stranded cost” could end up on your bill.
