At its latest open meeting on February 20, 2025, the Federal Energy Regulatory Commission (FERC) issued an order directing PJM Interconnection, L.L.C. (PJM) and the PJM Transmission Owners (PJM TOs) to demonstrate why the PJM Tariff’s lack of clear rules for co-location arrangements is acceptable or to explain the Tariff changes they would propose to address co-location issues (Show Cause Order). FERC’s Order is focused on the PJM region because there are several contested FERC proceedings involving co-location arrangements in PJM. However, FERC has indicated that it intends to act quickly on co-location arrangements across its jurisdiction. Accordingly, the results of the PJM Show Cause proceeding will likely serve as precedent in other RTO and non-RTO regions under FERC’s jurisdiction.
