Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.

Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

Reported lifecycle history

  1. Under construction

    Microsoft told the Anne Arundel County Council it started building the campus in the Annapolis Junction Business Park in 2020 and has remaining phases to develop. The amended moratorium (Bill 63-26) allows future phases of existing data centers to continue.

    Underlying source

Source notes

Microsoft bought the Annapolis Junction Business Park site in 2020. Microsoft's director of government affairs described 'remaining phases of this project', and the Banner says the campus has generated millions in county tax dollars. An aggregator lists 8201, 8211, 8221 and 8321 Dorsey Run Road; that is not verified from a primary source. The pin is the Annapolis Junction place point (approximate). Some buildings may already be operating; the status reflects ongoing phased construction.
