Summary
This 8-K filing from Entergy Corporation's subsidiary, System Energy Resources, Inc. (SERI), details significant changes to two key agreements impacting the allocation of capacity and costs related to the Grand Gulf Nuclear Station. First, the Unit Power Sales Agreement (UPSA) was amended, effective October 1, 2025, to remove Entergy Louisiana, LLC's participation. This amendment realigns the capacity and energy cost allocations among the remaining affiliate operating companies: Entergy Arkansas, LLC (24.19%), Entergy Mississippi, LLC (56.38%), and Entergy New Orleans, LLC (19.43%). Second, and concurrently with the UPSA amendment, SERI and the revised group of affiliate operating companies entered into a new "2025 Availability Agreement" and related "Assignments of 2025 Availability Agreement." This new agreement replaces a prior Availability Agreement that had effectively never been utilized since its inception. The 2025 Availability Agreement ensures SERI has adequate cash resources to cover its operating, interest, and shutdown costs, with obligations for payments or subordinated advances now falling upon the "2025 Affiliate Operating Companies" according to the new allocation percentages. The termination of the prior agreement and the entry into the new structure were approved by bondholders and the FERC, ensuring continuity and updated financial security for SERI.
