Amazon Web Services is looking to establish a data center campus in Calvert County, Maryland.

As reported by The Baynet, the company has presented a potential data center development during a recent open house meeting. No formal proposal has been submitted.

The project would be worked on with Constellation Energy, with the site near the Calvert Cliffs Nuclear Power Plant at 1650 Calvert Cliffs Parkway.

Thus far, Amazon has conducted preliminary review work, regulatory analysis, site evaluation and early design concepts, but has not submitted any hard plans for the project.

Based on a concept design shared by AWS during the meeting, the campus could have up to eight data centers to the south and west area of the nuclear plant. The property is already zoned for heavy industry use, and would not need to be rezoned for the project to proceed.

Details about the size of the buildings or expected IT capacity have not been shared. It's unclear if the facilities would have a behind-the-meter connection to the nuclear plant.

AWS has previously announced plans to expand its US East (Northern Virginia) cloud region into Maryland. In April 2025, the company said it would be taking up space in TPG’s Quantum Frederick Park in Adams town, around 100 miles away from Calvert County.

The cloud giant is also set to land its US-Ireland subsea cable, Fastnet, in the state.

While AWS has presented on the possibility of developing the site near the power plant in Calvert County, it is not alone in its interest.

Natelli Holdings targets Calvert County campus

The Calvert County website also notes that real estate firm Natelli Holdings is interested in developing on land south of the potential AWS campus, at 10475, 10485, & 10495 Solomons Island Road.

The attached presentation suggests a four-building campus could be developed at the site, for which Natelli would commit $30 million in investment. A meeting to discuss the project further will be held on April 6.

Response to the prospect of data center developments in the area has not necessarily been positive. At the start of March, during a separate planning commission meeting, commissioner Mike Hart made a motion to put in place an immediate 24-month moratorium on “any approvals, permits, rezoning, plans, construction, authorizations, or any other official acts related to a data center development, until a comprehensive environmental study evaluating land, water, and air impacts is completed and formally presented to the public.”

Local residents also voiced concerns about the lack of transparency up to that point, as well as opportunity for public input. Others told the meeting that development was necessary for the economic wellbeing of the area in future years.

Natelli Holdings was previously looking to develop a 250MW campus in North Dakota, known as the New Hill Digital Campus. The company was keen to construct four buildings on 190 acres outside Raleigh in New Hill, Wake County, but withdrew its application last month.
