Provider notes

Energy. Reuses the retired Dickerson coal plant's existing transmission lines and substation infrastructure; the application also includes a utility-scale battery storage facility on the site.

Water. River-water cooling proposed; a permit application seeks up to two million gallons per day from the Potomac on peak days. The Potomac was named America's most endangered river of 2026 by opponents of the project.

Community. Sustained opposition from Montgomery County community and environmental groups. The County Executive issued a six-month permit pause on June 12, 2026, the County Council enacted an 18-month moratorium on July 28, 2026, and the developer challenged the moratorium in court.

Some source-reported values are held out of this page.

These reviews flag conflicting scope, inconsistent source text or support that has not been established. A withheld value may appear in the explanation, but is not displayed as an established field. The upstream row remains attributed under Sources.

  • Cooling: Previously held pending provider-field review. The concern has not been resolved by an independent source review for this captured edition; the field remains withheld.

What the source record says

Five-building campus proposed by California-based Atmosphere Data Centers on the site of the decommissioned Dickerson coal power plant on the Potomac River. Single-source record: the developer's own filings were not independently retrieved. Re-checked 2026-09-10: status confirmed PROPOSED, no change -- existing record already fully captures the June 2026 six-month permit pause and July 28, 2026 18-month Council moratorium. New detail found this run: Atmosphere withdrew its legal appeal of Elrich's now-moot six-month executive-order moratorium after the Council's 18-month moratorium superseded it, and a separate county ordinance indefinitely prohibiting data centers was set to take effect 2026-08-17. This is regulatory-posture detail, not a status-enum change.

Capacity is not ranked or totaled here.

Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
