Provider notes
Energy. Adjacent to Calvert Cliffs Nuclear Power Plant (1650 Calvert Cliffs Parkway). AWS in potential partnership with Constellation Energy. Behind-the-meter nuclear connection under evaluation but not confirmed.
Community. Calvert County commissioners rejected a proposed 24-month moratorium on data center approvals at April 7, 2026 meeting (3 voted no, 2 voted yes). County zoning ordinance effective approximately March 2025 defines data center use standards for heavy industrial zones including setbacks, design, and noise requirements.
What the source record says
Very early-stage: AWS states no formal proposal submitted as of DCD article date. Site plan application filed May 2026. Concept design shared at community open house shows up to 8 buildings south and west of Calvert Cliffs nuclear plant. Capacity not disclosed by AWS. Coordinates approximate for Calvert Cliffs area.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
Status history supplied by the source
- 2026-03 · source-reported 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).
- 2026-08-26 · source-reported 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announced the withdrawal in an Aug. 4, 2026 press release; the county's data center page now records the application as withdrawn and states no site plan applications for data center development are pending.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.

Compute Atlas 1.34.1 with retained prior rows and publication holds. This is a DataCenterData composite, not an unmodified publisher edition. This row uses the captured source from 1.34.1, source as of 2026-10-14T20:40:52.293Z.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
