Maryland Moves to Regulate Large Data Centers After PJM Shortfalls

Lawmakers and state regulators moved in early January to craft new rules for very large data centers, citing concerns that rapid growth in computing facilities places heavy new demand on the electric grid. The policy push followed heightened attention to electricity capacity shortfalls in PJM, the regional grid operator, which state officials and energy stakeholders say underscored a need for clearer state oversight and stronger conditions on interconnection and grid reliability.

Proposals under discussion included requiring state-level certificates or state review for very large data centers, implementing new rate schedules and interconnection requirements, measures to require or incentivize onsite generation or battery storage, and rules to curtail data center load during peak periods. Together, these options would give state institutions tools to condition approvals on investments in resilience and to limit unplanned strain on local distribution systems during high-demand events.

The policy choices carry direct implications for Baltimore City. Data center projects can bring construction jobs and property tax revenue, but they also create local concerns about air quality, noise, land use, and the allocation of infrastructure costs. If utilities pass interconnection and grid upgrade costs onto residential and small commercial ratepayers, the economic burden could shift away from high-demand commercial customers. Conversely, requirements for onsite generation or storage could mitigate peak demand impacts but raise development costs that affect project economics and local tax yields.

Institutionally, the debate will hinge on the balance between state-level planning and local land-use authority. State review or certificate requirements aim to create consistency across jurisdictions and address regional grid impacts, while cities and counties have traditionally managed zoning and permitting. How Maryland reconciles those authorities will determine whether Baltimore and surrounding jurisdictions retain discretion over siting and community protections.

Regulatory tools under consideration would also alter utility practice. New rate schedules could encourage off-peak operations or demand flexibility. Interconnection standards could require earlier coordination between developers and grid operators to ensure upgrades are planned and financed in a transparent way. Curtailment rules and incentives for onsite batteries would change operational assumptions for data centers and could improve reliability during stress events.

These proposals were framed as likely priorities for the 2026 General Assembly session. Residents and local officials should expect bill filings, committee hearings, and public comment opportunities in the coming months. Civic engagement will shape whether Maryland adopts strict statewide controls, leans on market-based incentives, or preserves greater local authority over siting and community protections. The final policy mix will determine how Baltimore balances economic development from data centers with energy reliability, environmental impacts, and fairness for ratepayers.
