Data Centers in Maryland: Lawsuits, Disputes, and Your Rights
Maryland's data center growth centers on Frederick County's Quantum Loophole campus, but the sharpest fight is over the 67-mile Piedmont Reliability Project transmission line, where farmers are resisting right-of-way acquisition backed by eminent domain. What Maryland landowners and neighbors can do, and how to tell us about your situation.

Key Takeaways
- Maryland's biggest data center conflict is not about a building, it is about a wire: the 67 mile Piedmont Reliability Project, a PSEG transmission line across Baltimore, Frederick, and Carroll counties driven by regional data center load.
- Farmers along the route have organized against right-of-way acquisition; PSEG has gone to court for survey access to private land and reserves eminent domain to take easements if owners will not sell.
- The Quantum Loophole campus in Frederick County anchors Maryland's own data center growth, converting a former industrial site into a gigawatt-scale development.
- Landowners in a transmission path have real leverage: they can contest survey access, challenge the project's necessity in regulatory proceedings, and fight for full compensation with counsel if eminent domain is exercised.
- Maryland lawmakers have started responding: HB 120 would impose a moratorium on certain data center co-location arrangements, part of a national wave of data center bills.

In this article
In Maryland, the data center fight runs through farmland. The state's growth market is Frederick County, where the Quantum Loophole campus is turning a former industrial site into one of the region's largest data center developments. But the dispute affecting the most Marylanders is the Piedmont Reliability Project, a 67 mile PSEG transmission line across Baltimore, Frederick, and Carroll counties, planned largely to serve data center driven load. Farmers along the route have refused survey access and organized against right-of-way acquisition, and the developer has responded with court petitions and the reserved threat of eminent domain. If you own land in the path, or live near a Maryland data center, here is where things stand and what you can do.
The data center footprint in Maryland
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.
What residents are dealing with
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.
Lawsuits and disputes in Maryland
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.
Your legal options in Maryland
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 live near a Maryland data center
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.

Your rights do not depend on whether someone in Maryland has sued yet. Start with whether you can sue a data center, then what to document now, because the evidence you gather today is what a lawyer will ask for whenever you act.
Frequently asked questions
Can I sue a data center in Maryland?
Yes, Maryland law allows nuisance and property damage claims against a facility whose noise, dust, or other impacts seriously interfere with your home, though no such suit against a Maryland data center is documented as of August 2026. The state's active fight is over the Piedmont Reliability Project transmission line, where landowners are resisting right-of-way acquisition.
Can they take my land for the Piedmont Reliability Project?
PSEG has reserved eminent domain for the 67 mile line and has pursued court-ordered survey access where owners refused entry. Condemnation requires legal process and full compensation, and landowners can contest survey petitions, participate in proceedings over the line's necessity and route, and negotiate or litigate the price with counsel. Do not sign an easement without legal advice.
What is the Quantum Loophole data center in Frederick County?
It is a master-planned, gigawatt-scale data center campus on a former industrial site in Frederick County, the anchor of Maryland's data center growth. No litigation over the project is documented, but its scale drives regional power and water demands, including the transmission build-out now contested across three counties.
Is Maryland restricting data centers?
A bill known as HB 120 would impose a moratorium on certain data center co-location arrangements, part of a national wave of state data center legislation in 2026. It is a bill, not a law, as of August 2026, so residents concerned about growth should engage both locally and in Annapolis.
Should I accept a right-of-way offer from a transmission developer?
Not without a lawyer. Initial easement offers are negotiable, and compensation should cover not just the strip taken but damage to the value and use of your remaining land. Landowners in the Piedmont corridor have organized precisely because collective, counseled negotiation produces better outcomes than signing alone.
