On Friday, December 18, 2016, FERC approved Reliability Standard PRC-005-6. Previously proposed versions (PRC-005-3, PRC-005-4, etc.) will not become effective or enforceable.
• Transmission Owners (TO)
• Generation Owners (GO)
• Distribution Providers (DP)
The Standard change now includes Automatic Reclosers, Sudden Pressure Relays, Remedial Action Schemes, and some supervisory relays for Reclosers. FERC approved a single implementation plan for these changes. Those components and/or facilities newly introduced by PRC-005-6 (including Sudden Pressure Relaying, Automatic Reclosing Components, and dispersed generation resources) will be covered by the following Implementation Plan:
• Requirements R1, R2, and R5
> For Automatic Reclosing Components, Sudden Pressure Relaying Components, and dispersed
generation resources, entities shall be 100% compliant on the first day of the first calendar quarter
12 months following applicable regulatory approvals of PRC-005-6 (effective date January 1, 2017)
• Requirements R3 and R4
> For Automatic Reclosers (including supervision) and Sudden Pressure Relays with a six year
interval, the entity must have 30%, 60%, and 100% of devices tested by 36 months (or end of first
plant outage if longer than 36 months between outages), 72 months, and 84 months after
January 1, 2016
> For a 12-year interval, the entity must have 30%, 60%, and 100% of devices tested by 60 months,
108 months, and 156 months after January 1, 2016
No changes were made to the implementation plan for transition from PRC-005-1 to PRC-005-2(i). As such, all components with existing requirements under currently effective PRC-005-2(i) will continue to follow the PRC-005-2(i) implementation plan. The PRC-005-2(i) Standard will remain in effect until an entity implements the new PRC-005-6 Standard.

The enforcement date for PRC-005-6 was January 1, 2016.
