AWS Susquehanna-Cumulus Nuclear Data Center Campus

AWS acquired the Cumulus data-center campus adjacent to Talen Energy's Susquehanna nuclear plant in 2024. Data Center Dynamics and Power Engineering reported the transaction as a $650 million sale of a 960 MW Cumulus campus, with AWS power commitments ramping in 120 MW increments and an option to cap commitments at 480 MW. Utility Dive later reported that FERC rejected the amended interconnection agreement that would have expanded direct behind-the-meter co-located load from 300 MW to 480 MW.

ADCI removes the selected 960 MW value from this legacy acquisition record because the broader AWS Pennsylvania AI Innovation Campuses and Susquehanna PPA record now carries the selected 1,920 MW Talen/AWS power-supply envelope. This site remains important as a concrete Susquehanna-adjacent AWS campus, but its older 960 MW expansion envelope is treated as overlapping child capacity rather than independent selected public MW.
