Maryland Environmental Groups Demand Statewide Pause on Data Center Development

Over 60 environmental groups in Maryland are calling for a statewide moratorium on new data centers until their environmental and community impacts are fully assessed. Fourteen of the state's 24 jurisdictions have already enacted local bans, creating a patchwork of regulations. The groups point to a pending state study on data centers' effects on air, water, and the electricity grid as a reason for caution.
The Aug. 27 letter from the coalition arrives just days before the state's commissioned study on data center impacts was due to be submitted to the governor and General Assembly. That analysis, coordinated by the Department of Legislative Services, was produced jointly by the Maryland Department of the Environment, the Maryland Energy Administration, and the University of Maryland's business school, covering effects on air, water, the Chesapeake Bay watershed, and the electricity grid.
The advocacy groups' letter highlights a 44 percent rise in residential energy bills between 2020 and 2025, which they largely attribute to data center demand. The issue has become politically charged, with Republican challenger Dan Cox supporting a statewide ban on hyperscale facilities ahead of the November election, while the current patchwork of local moratoriums leaves many counties without clear protections.
This push for a statewide moratorium could reshape how Maryland balances economic development with environmental protection. Residential ratepayers may face continued bill increases if data center growth proceeds unchecked, while communities near proposed facilities—often low-income and minority neighborhoods—could bear disproportionate environmental burdens. The election timing suggests the issue may influence voter turnout among environmentally concerned constituents. A statewide policy, if enacted, could also set a precedent for other states grappling with AI-driven energy demand, potentially slowing the industry's expansion nationwide.
