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. Proposed

    AWS held community open house; described project as 'preliminary review work, regulatory analysis, site evaluation and early design concepts.' Site plan application filed May 4, 2026 with fees paid May 18. Up to 8 data centers proposed. No rezoning required (already heavy industry zoning).

    Underlying source
  2. Cancelled

    Amazon Data Services Inc. formally withdrew its Calvert Technology Center Conceptual Site Development Plan application and decided not to pursue the proposed data center project in Calvert County. Calvert County Government announced the withdrawal in an Aug. 4, 2026 press release; the county's data center page now records the application as withdrawn and states no site plan applications for data center development are pending. The withdrawal followed voter backlash in the county's June 23, 2026 primary, and the county subsequently passed a six-month moratorium on data center site plan approvals effective Aug. 28, 2026.
