## State-level measures in Maryland

Every statewide moratorium, pause, siting restriction, or tax-incentive rollback in Maryland we can verify against a primary source. Strongest status first.

| Measure | Status | What it does | Source |
| --- | --- | --- | --- |
| Maryland (Veto Override - Impact Study)Maryland: The Maryland General Assembly overrode Governor Moore's veto (Senate 44-0, House 111-24), enacting a law requiring a comprehensive environmental | In force 2025-12 | The Maryland General Assembly overrode Governor Moore's veto (Senate 44-0, House 111-24), enacting a law requiring a comprehensive environmental and economic analysis of data center expansion. The report is due September 2026 and must examine the cumulative impact of data center growth on electricity generation needs, grid capacity, water resource demands, and greenhouse gas emissions. |  |
| HB 1532Maryland: Governor Wes Moore signed HB 1532, the Utility RELIEF (Reducing Energy Load Inflation for Everyday Families) Act, into law on or about April 15 | In force 2026-04 | Governor Wes Moore signed HB 1532, the Utility RELIEF (Reducing Energy Load Inflation for Everyday Families) Act, into law on or about April 15, 2026, the day after the General Assembly passed it on the final day of session (April 13/14). The bill's data center provisions create a large-load registry program for grid management, require data centers to pay for transmission, distribution, interconnection, and new capacity costs (preventing cost-shifting to other ratepayers), and incentivize data centers to bring their own clean energy generation with battery backup (effective 2028). Top-tier projects receive 12-month expedited environmental permitting and priority interconnection. Critics including Food & Water Watch criticized provisions they characterized as pro-industry. The law saves Maryland families an estimated $150/year on energy bills. |  |
| Executive Order 01.01.2026.16Responsible Data Center Development framework and review task force | In force 2026-09 | Gov. Wes Moore signed an executive order on Sept. 23, 2026, effective immediately, creating a Maryland Data Center Task Force that reviews every data center of 25 MW or more that seeks any state action, rates each as Aligned, Conditionally Aligned or Not Aligned with a five-part framework, and publishes a monthly public dashboard. It does not pause construction; state permits, approvals and incentives are to be informed by each project's alignment with the framework. |  |
| Executive Order on Data Centers | Paused 2026-09 | An executive order creates a review process for large data centers, adds a public dashboard and a task force, and signals a push to end a key tax exemption. The order comes as the costs of data centers are under scrutiny nationwide. |  |
| SB 596Demand response and storage for large-load customers | Proposed 2026 | Would incentivize large-load customers of 25 MW or more to participate in demand response and onsite power storage programs. Introduced; pending. |  |
| Frederick County (Pippy state moratorium bill)Maryland: Frederick County Delegate Jesse Pippy introduced a bill proposing a data center moratorium specifically for Frederick County while the state conducts | Proposed 2026-03 | Frederick County Delegate Jesse Pippy introduced a bill proposing a data center moratorium specifically for Frederick County while the state conducts a comprehensive study of data center impacts. The legislation responds to growing community concern after the Frederick County Council voted 5-2 to adopt a 2,615-acre 'Critical Digital Infrastructure' overlay zone, which prompted residents to launch a referendum petition campaign that gathered over 22,000 signatures. Maryland counties more broadly have been calling on the data center industry to slow down. Fcdcreferendum.org does NOT display a live signature count; the 22,169 figure was removed. The 21,029 figure was the Board of Elections certified count at ballot qualification (CCAN source). Signature goal was 18,000 by March 15 per the committee's own site. Pippy's state moratorium bill died at MD sine die Apr 13, but the citizen referendum on the data center overlay zone was certified for the Nov 2026 ballot Apr 3 with 21,029 valid signatures (now facing legal challenges). |  |
| New data centers in neighboring Maryland to get additional scrutiny under governor's order | Proposed 2026-09 | Governor Wes Moore is creating a state task force to examine new data center proposals in Maryland and advise local jurisdictions on whether they meet state standards. However, he stated that the final decision on data center projects will remain with local governments. |  |
| HB 905Sales and Use Tax Exemption, Qualified Data Center Personal Property, Eligibility | Failed / vetoed 2024-02 | Maryland HB 905 (2024): Sales and Use Tax Exemption, Qualified Data Center Personal Property, Eligibility. Last action 2024-02-08: Hearing 2/29 at 1:00 p.m. (Ways and Means). |  |
| HB 120Moratorium on construction of new data centers | Failed / vetoed 2026 | Would prohibit new data centers statewide until co-location and generation legislation is enacted; heard in committee Feb 3 but did not advance before sine die. |  |
| HB 560Maryland HB 560 (Del. Palakovich Karr, D - Ways & Means) would repeal the existing exemption from sales/use tax and property tax for personal property used | Failed / vetoed 2026-01 | Maryland HB 560 (Del. Palakovich Karr, D - Ways & Means) would repeal the existing exemption from sales/use tax and property tax for personal property used at qualified data centers in Maryland. Part of a 2026 wave of state-level legislation rethinking data center tax incentives, over 300 state data center bills have been filed across 30+ states in just six weeks of the 2026 session. Maryland separately overrode a Moore veto to mandate a comprehensive data center impact study (due Sept 2026), reflecting growing legislative skepticism of data center subsidies as energy costs rise. HB 560 (repeal data center tax exemptions) never advanced past its Feb 12 Ways & Means hearing; MD adjourned sine die Apr 13, 2026. |  |
| HB 1595Maryland HB1595 authorizes Baltimore City and county governing bodies to establish a special personal property tax subclass for qualified data centers and set | Failed / vetoed 2026-02 | Maryland HB1595 authorizes Baltimore City and county governing bodies to establish a special personal property tax subclass for qualified data centers and set a rate up to 2.5x the standard real property tax rate. The bill emerged from Frederick County's push for local taxing authority over data center equipment after the county discovered data centers' vast server farms were taxed at the same rate as other business personal property. The legislation was introduced February 15, 2026 and referred to the Ways and Means Committee. HB 1595/SB 427 (local property-tax authority over data centers) did not pass; MD sine die Apr 13, 2026. |  |
| HB 1411Maryland: In Maryland, HB 1411 would require large-scale data center operators to report environmental and resource impacts publicly. | Failed / vetoed 2026-03 | In Maryland, HB 1411 would require large-scale data center operators to report environmental and resource impacts publicly. Mandates jurisdictions with 10,000+ residents create formal data center management plans by 2027. Includes $1,000/MW payment into EmPOWER program for low-income assistance. HB 1411 did not pass the 2026 Maryland session (sine die April 13, 2026). The community's stated objective was to mandate public environmental reporting from data centers (HB 1411). |  |

### Where Maryland stands

Across the whole tracker we hold 334 state-level measures in 49 states and 1253 city and county measures, against 1419 primary sources. Maryland accounts for 12 of the state-level measures and 32 of the local ones.

By total measures on record it is #12 of the 50 states and DC carrying any tracked action, and #14 by city and county measures alone. Ranking is by count of sourced entries in this dataset, so it measures documented activity, not the size of the buildout.

## What does bind large loads in Maryland

A moratorium is only one way a data center gets stopped. The grid operator decides whether it can connect at all, and on what terms. Maryland sits in 1 footprint.

PJMDominant

Large loads must bring new capacity or be curtailed first. Filed, pending at FERC.

Entire state in PJM (BGE, Pepco, Delmarva, Potomac Edison).

## States next door

4 of the 5 states bordering Maryland have at least one data-center measure on record. Restrictions tend to travel between neighbors, so this is usually where the next one comes from.

### How to read this page

In force = a moratorium, siting restriction, or tax-incentive rollback that is currently enacted, by statute or executive order. Paused = a temporary hold on new incentives or applications. Proposed = introduced and still pending. Failed / vetoed = died in committee, was voted down, or was vetoed.

This page is generated from the same primary-sourced dataset as the national [U.S. Data Center Moratorium Tracker](https://savrn.com/data-center-moratorium-tracker) and is re-checked on the same weekly cycle, whether or not anything changed. Legislative status changes quickly; it is informational, not legal advice. Spot something out of date in Maryland? [Tell us](https://savrn.com/contact).

## Why Maryland is pushing back

The objections repeat from state to state: strain on the electric grid, water drawn for cooling, and the sense that a facility takes local resources without giving much back. SAVRN builds AI factories designed around those three objections: on-site power that does not lean on the public grid, direct-to-chip cooling that does not consume municipal water, and a training institute that puts local people to work inside the building.
