Amazon and Talen Energy Pivot to $18 Billion Grid-Connected Nuclear PPA
Following the Federal Energy Regulatory Commission's (FERC) landmark November 2024 rejection of an amended Interconnection Service Agreement (ISA) that would have allowed Amazon Web Services (AWS) to expand its behind-the-meter, co-located data center at Talen Energy's Susquehanna Nuclear Plant (Docket ER24-2172), the two companies executed a massive strategic pivot.
In June 2025, Amazon and Talen announced a 17-year, $18 billion power purchase agreement (PPA) running through 2042, securing 1,920 megawatts of carbon-free nuclear energy to power AWS's expanding AI and cloud data center footprint in Pennsylvania.
Instead of bypassing the regional transmission grid through co-location, the revised agreement shifts to a "front-of-the-meter" (grid-connected) model:
"The current co-located power arrangement will shift to a “front-of-the-meter” setup after a transmission reconfiguration in Spring 2026. From then, Susquehanna’s nuclear output will feed directly into the PJM grid, with PPL Electric Utilities managing transmission."
This grid-connected model directly addresses FERC's initial concerns regarding cost socialization and grid reliability. Under this arrangement, PPL Electric Utilities (the local regulated distribution utility) will manage the transmission of Susquehanna's power, allowing the large load to support grid infrastructure investments rather than bypass them. Christine Martin, President of PPL Electric Utilities, highlighted the benefits of this structure:
“Connecting large load customers like data centers to our transmission system helps lower the transmission component of energy bills for all customers.”
This $18 billion deal is part of a larger $20 billion commercial investment by Amazon in Pennsylvania. Additionally, the partnership includes evaluating the deployment of Small Modular Reactors (SMRs) and capacity uprates at the Susquehanna plant to inject new clean energy directly back into the PJM grid, establishing a new commercial blueprint for hyperscaler-utility-generator integration in the AI era.
