Provider notes
Energy. Connection to the SMECO transmission grid via a new on-site substation, cost borne by the developer.
Water. Developer states cooling would use non-potable water from the Solomons Wastewater Treatment Plant, averaging about 0.4 MGD and reaching roughly one million gallons on peak summer days, with about one third evaporated and two thirds recirculated.
What the source record says
Four data center buildings of roughly 200,000-220,000 sq ft each, about 70 feet tall, on 133 acres of county-owned I-2 heavy industrial land — the former Dominion Cove Point laydown site — paired with a pledged $30 million regional park on a separate Dominion-donated parcel. Capacity, water and jobs figures are developer-supplied. As of the county's data center page, no site plan application has been filed, and Calvert County's six-month moratorium on data center site plan approvals takes effect Aug. 28, 2026. Re-checked 2026-09-10: status confirmed PROPOSED, no change. Developer's own project page confirms 300 MW capacity (already in existing record, not re-filed) and states timelines remain 'subject to change...dependent upon final design development, regulatory approvals, and other factors' -- i.e. no firmer status yet. Attempted to fetch thebaynet.com's $30M-park and investment-cost coverage twice this run for investmentUsd and community.status but both returned HTTP 429 (rate-limited, not fetched) -- so no investmentUsd or community field is reported; those remain open for a future run against a non-rate-limited mirror.
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

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.
