FERC Approves Proposed Reliability Standards PRC-004-5 and PRC-010-2

On November 19, 2015, in Docket No. RD15-5, FERC issued a letter order accepting NERC’s petition seeking approval of Reliability Standards PRC-004-5 and PRC-010-2.  These Reliability Standards were developed in response to an Order No. 693 directive that NERC develop modifications to Reliability Standard PRC-010-0 to require an integrated and coordinated approach in all protection systems, including undervoltage load shedding (UVLS) programs.  The newly accepted Reliability Standards address the misoperation of UVLS equipment.  NERC submitted the proposed Reliability Standards for approval on June 8, 2015 and submitted a supplemental filing on October 23, 2015.
