Maryland's Data Center Construction Limits Signal Permitting Challenges Ahead

Executive Summary

Maryland Governor Wes Moore has signed an executive order limiting large-scale data center construction in the state, a move that has drawn broad public and political support. For developers with active or planned projects in Maryland, the order introduces material permitting risk and timeline uncertainty. Investors holding or underwriting Maryland data center positions should treat this as a regulatory repricing event. Local communities and infrastructure-constrained utilities stand to benefit; developers and capital allocators with Maryland exposure stand to lose ground. The InfraSale takeaway: begin evaluating alternative sites now, before the queue in competing markets tightens.

What Happened

Governor Wes Moore issued an executive order restricting the construction of large data centers in Maryland. The order reflects escalating concerns about the strain that hyperscale and large-format data center development places on local infrastructure — power capacity, water, roads, and community character among them.

The decision has received widespread support from the public and elected officials, signaling that this is not a fringe policy position but a durable shift in Maryland's regulatory posture. That level of political consensus makes a near-term reversal unlikely, regardless of industry lobbying pressure.

Specific project thresholds, exemption criteria, and agency review processes tied to the order were not detailed in the available source material. Developers with in-flight projects in Maryland should engage legal counsel immediately to assess whether existing entitlements provide protection or whether new review requirements apply.

Why This Matters

Maryland sits within the broader Mid-Atlantic data center corridor — a region that includes Northern Virginia's Loudoun County, the most densely concentrated data center market in the world. Developers priced out of or constrained in Northern Virginia have historically treated Maryland as a logical adjacency. That safety valve is now narrowing.

The executive order signals something larger than a single state's policy preference. It reflects a pattern emerging across multiple jurisdictions: communities and elected officials are asserting greater control over large-format infrastructure siting, particularly where power demand, water use, and traffic impacts are concentrated and visible. Maryland is the latest, not the last.

Industry context: Similar resistance has surfaced in parts of Texas, Georgia, and the Pacific Northwest, where local governments have either imposed moratoria, tightened zoning, or required expanded environmental review for data center projects. Maryland's action adds institutional weight to what had been a fragmented, county-level trend.

For developers and investors, the compounding effect matters most. Each state or county that tightens its regulatory stance reduces the pool of viable, permittable land — and increases competition for sites that remain open. Constrained supply with sustained demand is a repricing mechanism.

Power & Interconnection Impact

Data centers are among the most power-intensive land uses in the built environment. A single hyperscale facility can require 100–500 MW of dedicated capacity. Maryland's grid infrastructure, served primarily by Pepco Holdings and BGE within the PJM Interconnection footprint, was already facing queue pressure before this order.

The executive order likely adds friction to interconnection agreements by introducing permitting uncertainty upstream of utility application processes. Utilities underwriting new service agreements for large loads need confidence that the customer project will receive land use and zoning approval — a confidence that is now harder to establish in Maryland.

Assumption: Developers who were counting on Maryland sites to anchor PPA negotiations with data center tenants or wholesale power buyers may need to restructure those conversations around alternative locations, which could affect pricing, timeline, and counterparty appetite.

Developers evaluating any remaining Maryland opportunities should prioritize sites with existing substation proximity, demonstrated grid capacity, and pre-approved interconnection pathways — assets that are rare and will command a premium in a tighter regulatory environment.

Land, Zoning & Permitting Impact

The executive order directly complicates the zoning and entitlement process for new data center developments in Maryland. Even where underlying zoning may technically permit data center use, an executive order of this nature typically triggers additional review layers — environmental impact assessments, infrastructure capacity studies, or explicit gubernatorial or agency approval thresholds.

Developers should anticipate longer permitting timelines, more intensive community engagement requirements, and the real possibility of project denial at stages that were previously predictable. That uncertainty has a cost: it affects underwriting assumptions, debt terms, and equity return modeling.

Industry context: In markets where permitting timelines have extended from 12–18 months to 36+ months, some developers have seen land carry costs erode projected returns by 200–400 basis points. Maryland developers should stress-test their pro formas against extended timeline scenarios immediately.

The order also creates a chilling effect on speculative land acquisition in Maryland. Landowners who expected data center developers to pay a premium for large, utility-adjacent parcels may find that buyer pool contracting in the near term. Rezoning efforts that were predicated on data center demand will face a harder path to approval.

Investment Takeaway

This executive order is a regulatory pricing event, not a temporary inconvenience. Investors should update their Maryland data center assumptions accordingly.

Existing entitled projects with prior approvals may retain value — but verify whether the order applies retroactively or imposes new conditions on projects already in permitting.
Speculative land positions in Maryland marketed to data center buyers should be reassessed. Demand from that buyer pool will soften in the near term.
PJM-adjacent markets — including Delaware, Pennsylvania, and West Virginia — become incrementally more attractive as Maryland absorbs risk premium. Sites in those states with demonstrated interconnection capacity and favorable zoning should be evaluated now, before demand rotates.
Investors in Maryland data center debt should evaluate covenant structures and milestone schedules; permitting delays that extend construction timelines can trigger default or renegotiation events.
Operators and hyperscalers with Maryland in their site pipeline should not wait for regulatory clarity before beginning alternative site diligence. The lead time to entitle and energize an alternative site is measured in years.

InfraSale Market Angle

For developers active in the Mid-Atlantic corridor, Maryland's executive order is a direct signal to reallocate site diligence resources. The sites that will close fastest are those already in compliance-friendly jurisdictions with utility capacity committed — not those dependent on Maryland's newly uncertain permitting pathway.

Landowners in Maryland holding large parcels positioned for data center development should move quickly to understand whether their sites remain viable under the new framework. Those that do not meet the order's emerging criteria may need to be repositioned for alternative industrial or logistics uses.

Investors sourcing data center opportunities through InfraSale should filter for sites outside Maryland or for Maryland assets with existing entitlements that pre-date the executive order. Proactive engagement with local stakeholders in alternative Mid-Atlantic markets can shorten the diligence cycle considerably.

FAQ

How will the new regulations affect data center investments in Maryland?

Maryland's executive order introduces permitting uncertainty that directly affects underwriting assumptions, debt terms, and projected returns. Existing entitled projects may retain value, but new acquisitions or speculative land positions should be stress-tested against extended timeline scenarios and the possibility of project denial. Investors should treat this as a regulatory repricing event and update their Maryland exposure accordingly.

What are the permitting challenges developers now face for new data centers in Maryland?

The executive order adds review layers on top of existing zoning processes, likely requiring additional environmental or infrastructure capacity studies before approvals can be granted. Assumption: projects that were previously on 12–18 month permitting tracks may now face 36+ month timelines or outright denial, depending on project scale and how the order's thresholds are defined through agency rulemaking. Developers should engage legal counsel immediately to assess the order's specific application to their projects.

Are there alternative locations for data center development near Maryland?

Yes. PJM-adjacent states — including Delaware, Pennsylvania, and West Virginia — offer viable alternatives with comparable grid infrastructure and, in many cases, more permissive zoning environments. The broader Appalachian Power and Dominion Energy service territories in Virginia and West Virginia also have active interconnection capacity in some areas. Developers should begin alternative site diligence now rather than waiting for Maryland's regulatory picture to stabilize.

Does the executive order affect projects already in the permitting pipeline?

The source material does not specify whether the order applies retroactively to projects already in entitlement or only to new applications. Developers with in-flight Maryland projects should not assume existing applications are protected without a specific legal review of the order's language and any implementing regulations.

What should landowners in Maryland do if their parcels were being marketed to data center buyers?

Landowners should assess whether their sites meet any exemptions or thresholds the order establishes. If the data center buyer pool for their parcel contracts materially, repositioning the site for alternative industrial, logistics, or advanced manufacturing uses may be the most durable strategy for preserving land value.
