Data Centers in Maryland: Lawsuits, Disputes, and Your Rights

Maryland lives next door to the largest data center market on earth in Northern Virginia, and the industry has been spilling across the Potomac. The centerpiece is Quantum Loophole's campus in Frederick County, a master-planned, gigawatt-scale development on a former industrial site that is designed to host multiple hyperscale tenants. Frederick County's mix of land, fiber, and proximity to the Virginia cluster makes it the state's data center capital.

Growth at that scale needs transmission, and that is what the Piedmont Reliability Project is: a 67 mile high-voltage line proposed by PSEG across Baltimore, Frederick, and Carroll counties, part of the regional grid build-out that data center load is forcing. For hundreds of rural landowners, the project turned an abstract industry trend into a survey crew at the farm gate.

Maryland's reported concerns divide between the campus and the corridor:

• Right-of-way pressure on farmland. Farmers along the Piedmont route have organized against easement acquisition, refusing voluntary survey access. PSEG has pursued court orders to access private land for surveys and has reserved eminent domain as the backstop if owners will not sell easements.
• A line most locals will not use. Corridor residents object that the project's driver is data center load, much of it out of state, while the burden of towers, construction, and lost farm productivity falls on them.
• Growth impacts in Frederick County. A gigawatt-scale campus brings years of construction, water and power demands, and land use change to the county, the pattern that in older markets preceded noise and well complaints.
• Legislative response. HB 120, a co-location moratorium bill, was introduced in Annapolis, part of a national wave of state data center legislation.

The Piedmont Reliability Project fight. This is Maryland's central documented dispute. Organized farmers and landowners across the three-county route are resisting right-of-way acquisition for PSEG's 67 mile line. The developer has gone to court seeking survey access to properties whose owners refused it, and has made clear that eminent domain remains available for easements it cannot buy. The conflict has drawn national coverage as a test of when private land can be taken for data center driven infrastructure.

No neighbor suit against a Maryland data center. No lawsuit by residents against a data center operator or over a campus approval is documented in Maryland as of August 2026. The Quantum Loophole development has proceeded without the kind of rezoning litigation seen in Virginia or Georgia.

What you can do depends on whether you are in the corridor or near a campus:

• If you are in a transmission path: you can contest survey access petitions, participate in the regulatory proceedings that decide whether the line is needed and where it runs, and, if eminent domain is exercised, fight for full compensation for the easement and all damage to the remainder of your property. Do not sign an easement offer without counsel; initial offers are negotiable and landowners with lawyers routinely do better.
• If you live near a campus: Maryland recognizes private nuisance and property damage claims if a facility's noise, dust, or construction impacts seriously interfere with your home, seeking damages and mitigation.
• If a project is proposed near you: Maryland land use approvals can be opposed at hearings and challenged on procedural grounds, on short deadlines after approval. Our guide on fighting a proposed data center covers the playbook.
• Legislative engagement: bills like HB 120 show Annapolis is paying attention; testimony from affected residents shapes what passes.

Damage claims carry a statute of limitations that varies by claim type, and condemnation proceedings have their own strict timelines. A Maryland attorney can confirm what clock you are on.

If you own land in the Piedmont corridor, get every communication from the developer in writing, do not grant survey access or sign easements without legal advice, and connect with the organized landowner groups along the route. If you live near the Frederick County campus, document baseline conditions now: photos, a well test if applicable, and a dated log of noise and construction impacts.
