TLN Talen Energy Corporation

Talen Energy Corporation (“Talen”) (NASDAQ: TLN) released the following statement today in response to the Federal Energy Regulatory Commission (the “FERC” or “Commission”) order on Talen’s request for rehearing, which seeks reconsideration of the Commission’s November 1, 2024, order rejecting amendments to the Interconnection Service Agreement between PJM Interconnection, L.L.C., PPL Electric Utilities Corporation, and Talen subsidiary Susquehanna Nuclear, LLC (the “Susquehanna ISA”); the amendment would increase co-located load capacity at Talen’s Susquehanna nuclear power generation facility from 300 megawatts to 480 megawatts:

On November 20, 2024, Talen filed a motion for rehearing at FERC seeking reconsideration of the Commission’s November 1, 2024, order rejecting amendments to the Susquehanna ISA intended to memorialize certain operating parameters for co-located load at Susquehanna. Today, the Commission issued an order stating that it would address the request for rehearing in a future order. The Commission’s decision not to address the merits of the motion for rehearing within thirty days of filing makes the original November 1, 2024, order ripe for appeal to the appropriate United States Circuit Court of Appeals. Talen intends to pursue its appellate remedies. We continue to execute under the current ISA and work with AWS on alternative commercial solutions to expand beyond the approved 300-megawatt ISA.
