The largest concentration is Baltimore, with 9 data centers, followed by Calverton with 4 and Laurel with 3. The operators with the most data centers in Maryland are AiNET (7), Verizon Wireless (4), Atlantech Online (4), TierPoint (2), GI Partners (2). Colocation and interconnection providers appear most often because they publish building-level detail; hyperscale campuses appear where the operator or the county names the individual buildings. Not every operator discloses size. In Maryland, 6 publish a floor area and 6 publish a power figure, and each figure is shown against the data center it belongs to rather than added into one number. They are not the same measurement: one operator states the floor area of a single building, another the full capacity of a campus it has only announced. PJM runs the wholesale power market and the high-voltage grid for all of Maryland. 2 statewide measures governing data centers are on record, alongside 5 local pauses. 4 named projects in Maryland are delayed, blocked or under challenge. The list ## Maryland data centers by city Every data center identified in Maryland, grouped by the city or county it stands in, 48 of them across 26 places. Each entry names the operator and links to the source that states it. ### Data centers in Baltimore, Maryland Baltimore, Maryland has 9 data centers on this map, run by Lumen, AiNET, Crown Castle and Expedient. 2 publish a floor area and 1 publishes a power figure, shown against each one below. 1.
