AWS Susquehanna / Cumulus Campus

PRJ-AWS-SUSQUEHANNA · Site · Salem Township, Luzerne County, Pennsylvania, United States

Record last updated Oct 28, 2026

Scope and capacity

AWS owns the former Cumulus data-center campus beside the Susquehanna nuclear station in Salem Township. The $650 million acquisition was announced in March 2024, and the township describes the development as approximately 1,200 acres. Gray identifies itself as the construction lead for the continuing development, with that work beginning in 2025. Talen’s latest quarterly filing reports an April 2026 contractual transition to the revised PPA; that disclosure does not establish completion of all physical load-conversion work. Its maximum 1,920 MW supply commitment extends through 2042 and can also serve other Pennsylvania sites; it is not the campus’s measured IT load. The original 960 MW development potential is likewise not an operating-capacity figure. The revised arrangement names Talen as retail supplier and PPL for transmission and delivery through the PJM grid. The former behind-the-meter ISA appeal was voluntarily dismissed in January 2026. For PHL100, the river-basin commission approved up to 0.129 million gallons per day of consumptive use on a 30-day average, with Pennsylvania-American Water’s Berwick system as the primary supply. The approval covers evaporative cooling, not a measurement of actual consumption. A separate air-permit application proposes additional emergency generators; their ratings must not be counted as IT capacity. Current operating IT load, parcel-level expansion limits and the final disposition of that generator application remain unverified.

Headline: 1,920 MW Contracted

This record and AWS Salem Township cover development beside the Susquehanna nuclear plant and the Talen supply arrangement. Their supply figures overlap and are not additive.

Numbers refer to their stated physical boundaries and are not added together. Source dates, claim dates and record updates have different meanings. Missing dates and locators are not inferred.
