Maryland electricity customers are set to bear the cost of a $2 billion power grid upgrade, with critics arguing the investment is being driven primarily by the energy demands of artificial intelligence data centres located outside the state — raising fresh questions about who should pay for infrastructure expansions tied to the technology sector's rapid growth.
Maryland utility customers are facing a $2 billion upgrade to the state's electrical grid, a cost that critics say is being unfairly passed on to ordinary ratepayers to accommodate the surging power demands of AI data centres — many of which operate outside the state's borders.
The proposal has drawn significant scrutiny from consumer advocates and policy analysts who argue that residential and small business customers should not be required to subsidise infrastructure improvements that primarily benefit large technology companies and their energy-hungry computing operations.
AI data centres are among the fastest-growing consumers of electricity in the United States. Industry analysts estimate that data centre power demand could double or triple over the coming decade, driven by the computational requirements of training and running large language models and other AI systems. The grid upgrades in question are intended to ensure the regional transmission network can handle these increasing loads.
However, opponents of the cost-allocation model point out that if data centres are the primary beneficiaries of expanded grid capacity, those operators — not Maryland households — should bear the brunt of the associated costs. "It's a straightforward question of who benefits and who pays," one consumer advocate noted. "When ordinary families see their electricity bills rise to fund infrastructure for billion-dollar technology companies, that's a serious equity issue."
Utility companies and grid operators typically argue that broad infrastructure investments benefit all customers by improving reliability and resilience across the network. Proponents of the upgrade contend that a more robust grid ultimately serves everyone, reducing outages and supporting economic development that can bring jobs and tax revenues to the region.
The debate in Maryland reflects a broader national tension as grid operators across the country grapple with how to fund the massive infrastructure investments required to meet surging electricity demand. The mid-Atlantic transmission region, known as PJM Interconnection, has been at the centre of several high-profile disputes over cost allocation in recent years.
State regulators will ultimately determine how costs are distributed among ratepayers, utilities, and large commercial customers. Consumer groups have called for a more targeted approach that would require data centre operators and other large industrial users to pay a greater share of the upgrades their operations necessitate.
The outcome could set a precedent for how other states handle similar disputes as AI-driven power demand continues to accelerate.
Analysis
Why This Matters
- Electricity ratepayers in Maryland — and potentially across the country — could see bills rise to fund grid upgrades primarily driven by the AI industry's insatiable appetite for power.
- The case highlights a systemic question about cost allocation: as the tech sector drives unprecedented demand on public infrastructure, the rules for who pays have not kept pace.
- The outcome of Maryland's regulatory process could serve as a national template, influencing how dozens of other states handle similar disputes in the coming years.
Background
The rapid proliferation of AI systems since 2022 has triggered an extraordinary surge in data centre construction across the United States. Facilities operated by or contracted to major technology companies require enormous and continuous power supplies to run servers, cooling systems, and networking equipment at scale.
PJM Interconnection, the grid operator serving Maryland and 12 other states plus the District of Columbia, has been managing a backlog of data centre and other large-load connection requests. In 2024 and 2025, PJM announced billions of dollars in required transmission upgrades to accommodate projected demand growth, with the costs subject to complex regulatory allocation processes.
Historically, grid upgrade costs in the US have often been socialised across all ratepayers under the rationale that transmission improvements benefit the entire network. But the scale and specificity of AI-driven demand has prompted a growing movement to revisit these rules and require large commercial users to internalise more of the costs they impose on the system.
Key Perspectives
Utility companies and grid operators: Argue that transmission upgrades improve reliability for all customers and that socialising costs is the established, legally supported model. They contend the investments will support long-term economic growth in the region.
Consumer advocates and ratepayer groups: Contend it is inequitable to charge households and small businesses for infrastructure that disproportionately serves large, profitable technology corporations. They are pushing regulators to adopt "beneficiary pays" cost allocation principles.
Critics/Skeptics: Some analysts warn that even if regulators shift more costs onto data centre operators, companies may simply pass those expenses through to consumers of AI services — or threaten to relocate facilities to more favourable jurisdictions, potentially undermining the intended reform.
What to Watch
- Maryland Public Service Commission rulings on cost allocation methodology and how much of the $2 billion is assigned to large industrial users versus residential ratepayers.
- Federal Energy Regulatory Commission (FERC) proceedings on transmission cost allocation rules, which could override or harmonise state-level decisions.
- Whether other PJM states facing similar upgrade bills adopt comparable or divergent approaches, potentially creating a patchwork of regulatory outcomes across the region.
