Maryland Challenges PJM Over Billions in Data Center Grid Costs

Maryland officials have filed a federal complaint against PJM Interconnection, arguing that residents should not bear the $1.6 billion cost of grid upgrades required to power out-of-state AI data centers.

The rapid expansion of artificial intelligence is colliding with the economic realities of the American power grid. On May 7, 2026, the Maryland Office of People’s Counsel filed a formal complaint with the Federal Energy Regulatory Commission (FERC) against PJM Interconnection. The complaint targets a $1.6 billion transmission cost allocation that would see Maryland residents subsidizing the infrastructure needed to support massive data center clusters, many of which are located across state lines.

This legal challenge follows a period of unprecedented growth in power demand. PJM, which coordinates the movement of wholesale electricity in all or parts of 13 states, has advanced approximately $12 billion in transmission upgrades over the last two years. The regional grid operator projects a 32-gigawatt peak load growth by 2030, with nearly 30 gigawatts of that demand attributed specifically to the data center industry. As AI optimism drives stock valuations for firms like Intel, AMD, and Micron to record highs, the physical infrastructure required to sustain these computations is creating a fiscal burden for traditional ratepayers.

The Maryland Public Service Commission has moved to mitigate these impacts by accelerating the deployment of Virtual Power Plants and Distributed Energy Resource aggregators, with full access slated for early 2028. However, the immediate concern remains the PJM capacity auction costs, which surged from $2.69 billion in 2024 to an estimated $10.39 billion for 2025. Data centers are currently responsible for nearly half of the $47.2 billion in total auction costs projected through May 2028.

Maryland’s intervention argues that the current cost-sharing model violates the Ratepayer Protection Pledge, a policy framework supported by the White House to ensure that industrial energy users pay their fair share of system upgrades. Pennsylvania regulators have taken similar steps, advancing a model tariff designed to insulate residential consumers from the connection costs associated with the PJM demand surge. These state-level actions reflect a growing consensus that the economic benefits of the AI boom must be weighed against the reliability and affordability of the grid for the average taxpayer.

While some companies, such as Polestar, are doubling down on net-zero commitments despite a broader cooling in electric vehicle ambition, the primary challenge for the mid-Atlantic grid is one of raw capacity and cost allocation. The FERC previously directed PJM to revise its tariffs regarding AI data center co-location in late 2025, but the implementation of those revisions remains a point of contention as states fight to keep local utility bills stable.

With energy markets already strained by geopolitical volatility—including recent military exchanges in the Strait of Hormuz that pushed Brent crude past $104—the domestic battle over grid costs represents a second front for energy security. For Maryland and its neighbors, the goal is a pragmatic transition that supports technological innovation without compromising the financial stability of the households that keep the lights on.
