Data centers in Maryland: common questions

How many data centers are in Maryland?
More Than Just Parks tracks 42 active data center facilities in Maryland, each citing a public source: 29 operating, 5 under construction and 8 proposed. 18 more were canceled, withdrawn or blocked.
How much electricity do Maryland's data centers use?
We don’t publish a state total, and the reason matters: roughly four in ten facilities never disclose a capacity, so any sum would look like a census of Maryland's data center load while leaving out the sites that stayed quiet. Each facility page shows the figure its own source states. A single large campus can draw as much power as a small city.
Are Maryland data centers near protected land?
21 of the tracked facilities in Maryland sit within 10 miles of protected public land, measured to the real boundary of the nearest national park, wilderness area, wildlife refuge or conservation area; 0 sit within a single mile.

An email when a data center lands in the record here, proposed, breaking ground or stopped, with its size and how close it sits to protected land.

Every facility on this page cites a public record we can link to: industry reporting, facility trackers, company announcements, and local planning and utility filings, cross-referenced against protected public land. Part of the Data Center Tracker from More Than Just Parks. A row prints a capacity only where its own source states one.
