NERC Submits Proposed Reliability Standard PRC-005-4

On December 18, 2014, in Docket No. RD15-2, NERC submitted a petition seeking Commission approval of Proposed Reliability Standard PRC-005-4, Protection System, Automatic Reclosing, and Sudden Pressure Relaying Maintenance.  The proposed standard, which NERC is filing in response to FERC Order No. 758, adds Sudden Pressure Relaying, the misoperation of which can impact the reliability of the Bulk-Power System, to the applicability of PRC-005.  As a result of the addition of Sudden Pressure Relaying, applicable entities will be required to document and implement programs for the maintenance of applicable sudden pressure relays.
