Maryland Fights $2B Grid Bill for Out-of-State AI Data Centers
ANNAPOLIS, Md. — Maryland filed a complaint with federal energy regulators over a $2 billion grid upgrade bill the state says unfairly charges ratepayers for infrastructure serving out-of-state AI data centers, according to Tom’s Hardware.
The state argues the additional costs break promises made under ratepayer protection pledges, which were designed to shield consumers from bearing the burden of infrastructure investments that primarily benefit commercial operations in other jurisdictions.
The complaint, directed at the Federal Energy Regulatory Commission, centers on transmission grid upgrades managed by PJM Interconnection, the regional transmission organization that coordinates the wholesale electricity market across 13 states and the District of Columbia. PJM’s grid planning process allocates the cost of new transmission infrastructure across its member states, and Maryland contends that its residents are being asked to subsidize upgrades driven largely by surging electricity demand from AI data centers concentrated in Northern Virginia and other out-of-state locations.
The dispute reflects a broader tension across the United States as the rapid expansion of AI infrastructure — particularly the massive data centers required to train and run large language models — strains electrical grids and raises questions about who should pay for the resulting upgrades.
Data centers serving major AI operations can consume hundreds of megawatts of electricity, equivalent to the power needs of a small city. Northern Virginia’s “Data Center Alley” in Loudoun County has become the largest concentration of data centers in the world, with continued expansion driven by companies building AI capacity.
Maryland’s complaint to FERC argues that the current cost allocation formula unfairly distributes transmission upgrade expenses to ratepayers who receive little or no direct benefit from the new capacity. The state maintains that the entities driving the demand — primarily large technology companies operating data centers — should bear a greater share of the infrastructure costs.
The case could set a precedent for how states and federal regulators handle the allocation of grid upgrade costs as AI-driven electricity demand continues to accelerate nationwide. Several other states within the PJM footprint face similar concerns about rising transmission costs linked to data center growth.
Consumer advocates have expressed concerns about the impact of data center expansion on residential electricity rates. The challenge for regulators is balancing the economic development benefits that data centers bring — including jobs and tax revenue — against the financial burden on households that may see little direct benefit from the facilities.
FERC has not yet issued a ruling on Maryland’s complaint. The commission’s decision could influence how regional transmission organizations nationwide approach cost allocation for infrastructure driven by large commercial electricity consumers, including AI data center operators.
