Maryland Challenges $2 Billion Power Grid Cost Allocation for AI Data Centers
Key Takeaways
- ▸Maryland residents would pay $2 billion toward transmission infrastructure that primarily serves out-of-state AI data centers under PJM Interconnection's current cost allocation method
- ▸The state argues that cost responsibility should fall on geographic areas where infrastructure is built or directly on data center operators, not on Maryland ratepayers
- ▸Over 10 years, the $2 billion charge translates to $1.6 billion in additional costs for Maryland consumers—$823 million for residential, $146 million for commercial, and $629 million for industrial customers
Summary
Maryland's Office of People's Counsel (OPC) filed a complaint with the Federal Energy Regulatory Commission (FERC) challenging PJM Interconnection's plan to allocate $2 billion of a $22 billion grid upgrade cost to Maryland ratepayers. The power grid expansion was undertaken to support growing electricity demand from data centers, but Maryland argues that the state's consumers are unfairly subsidizing infrastructure projects that primarily serve out-of-state AI data center operations and other regions with greater data center concentration.
According to the OPC's complaint, Maryland consumers would bear an additional $1.6 billion in costs over the next decade from this allocation—translating to approximately $345 per residential customer, $673 per commercial customer, and $15,074 per industrial customer. The state argues that PJM's cost allocation methodology is fundamentally flawed, as Maryland will not meaningfully benefit from these transmission upgrades despite bearing a significant portion of the costs. Maryland advocates for cost responsibility to fall on the geographic areas where infrastructure is actually constructed or, following President Trump's "ratepayer protection pledge," directly on the data center operators themselves.
This dispute reflects growing national tension surrounding AI infrastructure expansion. Approximately 69 jurisdictions have implemented moratoriums on data center projects, and nearly half of Americans oppose having data centers built in their communities. The case underscores a critical policy challenge: as AI hyperscalers rapidly expand their computing infrastructure, the burden of massive power grid upgrades falls disproportionately on existing utility customers rather than on the companies profiting from the increased capacity.
