The Public Utilities Commission of Ohio (PUCO) this week approved a new AEP Ohio rate structure specifically targeting large data centers with loads exceeding 25 megawatts.

The decision, aimed at addressing transmission capacity concerns, imposes higher minimum demand charges, exit fees, and collateral requirements on data center customers.

The OMA pushed back on the decision in a statement, arguing that the tariff is discriminatory, lacks sufficient evidence, and will discourage business investment in Ohio. The OMA is evaluating options to appeal the decision.

Although the PUCO ordered AEP to lift its moratorium on new service connections, it made few changes to the proposed tariff, raising concerns about fairness and transparency. 7/10/2025
