Sort by any column. Named facilities link to their own page; a record OpenStreetMap carries without a name is listed by its element id, because there is nothing else to say about it.

The power behind Maryland's data centers
EIA-860M lists 247 operating power plants in Maryland totalling 13,504 MW of nameplate capacity, of which 16 are natural gas plants. That is the supply these 12 facilities draw on. None of these data-centre records states a load, so this page draws no line between the two — it only puts them in one place.
Data centers in Maryland: FAQ
- How many data centers are in Maryland?
- 12 are on the public record this directory reads: 0 in county or city permit GIS and 12 in OpenStreetMap. Maryland has no state register of data centres, so that is a lower bound rather than a count.
- Where are the data centers in Maryland?
- Mostly around Baltimore, which holds more of these records than anywhere else in the state. The map above plots all 12 and the city table breaks them out.
- Is there a data center near me in Maryland?
- The city table below groups every facility on record by city, which is the quickest way to find the data center closest to a given town. This site does not read your location.
- Are these AI data centers?
- Unknown, and no public record in Maryland says. A permit records a data center; it does not record the tenant or the workload. Where an AI data center exists in Maryland it is in this list without being labelled as one, and this page will not guess which.
- Who operates Maryland data centers?
- AiNET appears against more of these records than any other operator. Where a source names no operator the row says so rather than guessing one.
- How many Maryland data centers are under construction or planned?
- No source covering Maryland publishes a build status, so this page shows none. Status is only available where a county publishes its permit layer.
- How current is this, and what is left out?
- OpenStreetMap extract 2026-09-17; county permit capture 2026-09-12. Power draw, tenant, commissioned megawatts and lease terms are not in any of these public records and are not shown anywhere on this site.
