An oversight in updating the PJM Operating Agreement, Schedule 7 (regarding underfrequency relay obligations) when EKPC integrated into PJM in 2013, and confusion about the applicable UFLS requirement for EKPC created by a ministerial change to the definition of “PJM West Region,” necessitate a revision to the PJM OA to formally document the appropriate requirement for EKPC. A SERC regional reliability standard identifies the appropriate requirement for EKPC. This is the applicable requirement for EKPC that should be documented in the PJM OA, Schedule 7.
