Reliability Impact Assessments

Brandon Shores and H.A. Wagner RMR Arrangements. In 2023, we notified PJM of our intent to deactivate electric generation at both our Brandon Shores and H.A. Wagner facilities on June 1, 2025. However, PJM subsequently notified us that both Brandon Shores and H.A. Wagner are needed past their previously planned retirement dates to maintain reliability in PJM. In January 2025, we reached a settlement with key stakeholders on the terms of an RMR arrangement and filed with FERC the resulting Joint Offers of Settlement regarding both facilities’ RMR Continuing Operations Rates Schedules (the “CORS”). On May 1, 2025, the FERC approved the terms under which Talen will operate these plants through May 31, 2029, or until such time as the necessary transmission upgrades are placed into service. Beginning June 1, 2025, the CORS will provide an annual fixed-cost payment of $145 million ($312/MWd) for Brandon Shores and $35 million ($137/MWd) for H.A. Wagner, which includes a performance “hold back” of $5 million per year for Brandon Shores and $2 million per year for H.A. Wagner, each to be paid out based on unit performance. We will also receive separate reimbursement for variable costs and approved project investments.
