PUCO orders AEP Ohio to create data center specific tariff

COLUMBUS, OHIO (July 9, 2025) – The Public Utilities Commission of Ohio (PUCO) today issued an order directing AEP Ohio to file new tariffs applying to data centers. The Commission adopted a settlement agreement reached by AEP Ohio, PUCO staff, Ohio Consumers’ Counsel (OCC) and others.  

“Today’s order represents a well-balanced package that safeguards non-data center customers on an industrial and residential level while establishing a dependable and reasonable environment for data centers to continue to thrive within Ohio,” stated PUCO Chair Jenifer French. 

The Commission recognized AEP Ohio is faced with unpreceded load growth that requires it to construct significant electric transmission infrastructure to serve data center customers in its territory. In its order, the Commission noted the settlement safeguards other non-data center customers from cost-shifting risks of underused investments made to serve Ohio’s growing data center industry. 

AEP Ohio is ordered to file updated tariffs and lift its moratorium on connecting new data centers as soon as possible.
