Ohio Regulators Approve AEP Data Center Interconnection Rules
Key Insights
The Ohio PUC ordered AEP Ohio to update tariffs and lift a moratorium on connecting new data centers.
New rules require data centers larger than 25 MW to pay minimum monthly bills based on a percentage of their highest previous billing demand or contract capacity.
Data centers must demonstrate financial viability and pay an exit fee if projects are canceled or obligations are unmet.
The Data Center Coalition expressed disappointment, arguing the rules could dampen investment by inflating costs and imposing cumbersome regulations.
Why this matters: These regulations aim to balance supporting data center development with protecting other ratepayers from increased costs related to grid infrastructure upgrades and potential stranded costs. The outcome could influence how other regions address similar challenges.
In-Depth Analysis
The approved settlement agreement modifies the original proposal by requiring data center customers or their financial sponsors to provide collateral if the sponsor co-signs the contract. The rules mandate that data centers pay for at least 85% of their expected monthly energy needs, regardless of actual usage, to cover infrastructure costs. These requirements are set to last for up to 12 years, including a 4-year ramp-up period.
Commissioner Dennis Deters emphasized that these rules apply specifically to AEP Ohio’s territory, while acknowledging that the broader PJM region faces similar growth from data centers and the retirement of dispatchable generation. The Data Center Coalition, representing major companies like Google, Amazon, and Microsoft, voiced concerns that the decision deviates from established ratemaking principles and could hinder investment in Ohio's data center market.
