Talen and Amazon Move the Data Center to the Front of the Meter, and Sidestep FERC

Seven months after federal regulators blocked an expanded behind-the-meter arrangement at the Susquehanna nuclear plant, Talen Energy and Amazon Web Services have found another way to do much the same thing. On June 11 Talen announced a 1,920 MW power purchase agreement to supply AWS data centers in Pennsylvania from its majority-owned Susquehanna plant, the 2,475 MW station in Salem Township. The existing 300 MW co-location arrangement will shift to what Talen calls a front-of-the-meter framework, which the company says does not require Federal Energy Regulatory Commission approval.

Talen expects about $18 billion in revenue over the life of the contract at full quantity, according to its investor presentation as reported by Utility Dive. The difference between the old and new structures is the heart of the story. Under the original arrangement, the data center campus next to the plant took power directly, behind the meter. The electrons that power the data center still come, in practice, from a plant a short distance away.

Utilities argued that co-located data centers would avoid transmission and other charges while still relying on the grid for backup and stability, shifting costs onto other customers. Utility Dive reports the monitor's estimate that forecast data center load growth contributed to a $9.3 billion increase in capacity market revenue in PJM's last auction, for the 2025/2026 delivery year. The front-of-the-meter structure answers the first objection directly, because AWS will pay network charges. The structure also handles a practical issue that behind-the-meter deals tend to gloss over.

A nuclear unit is offline for several weeks every refueling cycle, and it can trip without warning. For Talen, the attraction is price certainty for its most valuable asset. The company presented the agreement as a platform to expand across its portfolio. The Talen-AWS restructuring shows that the co-location fight is less about physics than about who pays for what.
