Maryland's Office of People's Counsel (OPC) has filed a complaint with the Federal Energy Regulatory Commission (FERC) challenging PJM Interconnection's plan to charge the state $2 billion of a $22 billion grid upgrade intended to accommodate increasing demand from AI data centers. The complaint argues that Maryland ratepayers are unfairly subsidizing infrastructure costs for data centers located primarily in other states.
Maryland Ratepayers to Pay $1.6 Billion Over Next Decade
The $2 billion allocation translates to $1.6 billion in additional costs for Maryland consumers over the next ten years. Residential customers will bear approximately $823 million of this burden, equating to roughly $345 per customer. Commercial customers face $146 million in additional costs (approximately $673 per customer), while industrial customers will shoulder $629 million (approximately $15,074 per customer).
State Challenges PJM's Cost Allocation Methodology
Maryland's OPC argues that PJM Interconnection's methodology for distributing infrastructure costs places a disproportionate burden on Maryland ratepayers relative to the state's actual data center footprint. The forecasted electricity growth for Maryland is significantly lower than states like Virginia, Ohio, Pennsylvania, and Illinois, which host substantially more data center projects. Under the current calculation framework, Maryland customers would effectively subsidize grid upgrades benefiting other states.
State Proposes Direct Billing for Infrastructure Costs
The OPC contends that infrastructure costs should be allocated directly to the geographic areas where data centers are being constructed, or that companies developing these facilities should be billed directly for the grid upgrades necessary to support their operations. This approach would prevent ratepayers in states with minimal data center development from bearing costs for infrastructure that provides no direct benefit to their communities.
