Reported facts
Structured facts sourced from citations already on this record. Each fact traces to a source in the References section below.
- Location / acquisition (reported)
- AWS acquired Talen Energy's Cumulus data center campus adjacent to the Susquehanna nuclear plant in Salem Township, Pennsylvania (Luzerne County). Trade press reports ~960 MW campus scope and a ~$650M sale; treat dollar figure as press-reported (Data Center Dynamics; Data Center Frontier)
- Nuclear PPA (announced)
- June 2025 expanded PPA: Talen to supply Amazon up to 1,920 MW of carbon-free power from Susquehanna through 2042 (with extension options), ramping to full volume no later than 2032, for AWS data centers at the adjacent campus and potentially other Pennsylvania sites (World Nuclear News summarizing Talen, Jun 12 2025)
- Delivery structure (announced)
- After FERC rejected a behind-the-meter interconnection increase, the co-located load arrangement is transitioning to a front-of-the-meter retail model: Susquehanna power to PJM, Talen as retail generation supplier to Amazon, PPL Electric Utilities for transmission/delivery. Transmission reconfigurations expected Spring 2026 with a Susquehanna refueling outage (World Nuclear News)
- SMR / uprate exploration (announced)
- Talen and Amazon say they will explore building SMRs within Talen's Pennsylvania footprint and pursuing Susquehanna uprates to add net-new energy to PJM (World Nuclear News)
- Grid region
- PJM Interconnection region; Susquehanna is a two-unit boiling water reactor plant in Salem Township (World Nuclear News)
