Protection System Maintenance Reliability Standard

Pursuant to the section regarding Electric Reliability of the Federal Power Act, the Commission proposes to approve a revised Reliability Standard, PRC-005-3 (Protection System and Automatic Reclosing Maintenance). In addition, the Commission proposes to approve one new definition and six revised definitions referenced in the proposed Reliability Standard, the assigned violation risk factors and violation severity levels, and NERC's proposed implementation plan. Consistent with Order No. 758, the proposed Reliability Standard requires applicable entities to test and maintain certain autoreclosing relays as part of a protection system maintenance program. The Commission also proposes to direct NERC to submit a report based on actual performance data, and simulated system conditions from planning assessments, two years after the effective date of the proposed standard, which addresses whether the proposed Reliability Standard applies to an appropriate set of autoreclosing relays that can affect Bulk-Power System reliability. Further, the Commission proposes to direct NERC to modify the proposed Reliability Standard to include maintenance and testing of supervisory relays, as discusse
