POST #31: WHERE IN THE WORLD IS THE MARYLAND DATA CENTER STUDY?
⠀
Maryland's data center study was due September 1. It didn't come out.
⠀
Counties across Maryland paused data center development in part to wait for that report. It has not been delivered, and no agency has announced a new date.
⠀
This is not only a Calvert County question. Jurisdictions across the state are holding decisions open while they wait. Here is what the law requires, who voted for it, who is waiting on it, and what to ask.
⠀
WHAT THE LAW SAYS
⠀
Senate Bill 116, the Data Center Impact Analysis and Report, was sponsored by Senators Karen Lewis Young and Justin Ready. A cross-filed version, House Bill 270, was sponsored by Delegate Brian M. Crosby.
⠀
The law requires the Maryland Department of the Environment, the Maryland Energy Administration, and the University of Maryland Robert H. Smith School of Business to analyze the environmental, energy, and economic impacts of data center development in Maryland. The Department of Legislative Services coordinates those assessments into a final report.
⠀
The deadline written into the law is on or before September 1, 2026, to the Governor and the General Assembly.

⠀
WHAT THE STUDY IS SUPPOSED TO COVER
⠀
The Department of the Environment assesses potential impacts on the state's natural resources, including air and water quality, the state's ability to meet Chesapeake Bay restoration goals, and available mitigation technologies.
⠀
The Maryland Energy Administration assesses data center energy requirements, impacts on energy demand and supply, infrastructure needs, and the state's ability to meet greenhouse gas reduction commitments.
⠀
The University of Maryland School of Business assesses economic and fiscal impacts, including the likely effect on state and local revenues and expenditures, and the jobs likely to be created through construction and operation.
⠀
The Department of Legislative Services may request information from the Department of Natural Resources, the Department of Assessments and Taxation, the Department of Commerce, and the Public Service Commission.

⠀
HOW IT BECAME LAW
⠀
Governor Wes Moore vetoed the bill on May 16, 2025. His veto message stated that the three studies in that package would cost at least $1.28 million and would require coordination across numerous agencies and institutions. This study was budgeted at approximately $502,000.

⠀
The General Assembly overrode the veto on December 16, 2025. The Senate voted 44-0. The House voted 109-21.
⠀
Both versions became law. Senate Bill 116 is Chapter 10 of the 2025 Special Session. House Bill 270 is Chapter 3.

⠀
WHAT HAPPENED TO THE DEADLINE
⠀
On August 31, 2026, FOX45/WBFF reported that the study would not be delivered on time. Senator Lewis Young said she now expects the report before the next legislative session, which convenes in January 2027, and that she is drafting data center legislation regardless.

⠀
As of September 2, 2026, no revised delivery date has been announced by the Department of the Environment, the Maryland Energy Administration, the University of Maryland, the Department of Legislative Services, or the Governor's office.
⠀
HOW TO CHECK FOR YOURSELF
⠀
Reports submitted to the General Assembly are cataloged by the Department of Legislative Services Library. That catalog is the official record of whether a mandated report has been submitted, and it is public.

⠀
WHAT TO ASK
⠀
This report belongs to every county in Maryland, not just the ones with a project in front of them. Four questions have not been answered publicly:
⠀
When will the report be delivered?
⠀
Which of the three agency assessments are complete and which are not?
⠀
Will the report arrive before the General Assembly convenes in January 2027?
⠀
Will it arrive before local moratoriums expire?
⠀
The entities responsible are the Maryland Department of the Environment, the Maryland Energy Administration, the University of Maryland Robert H. Smith School of Business, and the Department of Legislative Services. Anyone can also ask their own senator and delegates, who are the recipients of the report under the law.

⠀
WHERE THIS LEAVES US
⠀
A study required by two chapters of Maryland law, budgeted at roughly $502,000, passed both chambers without a single senator voting against it. Its statutory due date has passed. Local moratorium clocks are running, and several expire before or during the next legislative session.
⠀
Maryland has neither the analysis nor a date for it.
