FERC-725G2, (Order in RD18-4-000) Reliability Standard for the Bulk Power System: Reliability Standard PRC-025-2

On March 16, 2018, the North American Electric Reliability Corporation (NERC, the Commission-approved ERO) submitted for Commission approval proposed Reliability Standard PRC-025-2, Generator Relay Loadability. The PRC-025-2 Reliability Standard addresses setting load-responsive protective relays associated with generation facilities at a level to prevent unnecessary tripping of generators during a system disturbance for conditions that do not pose a risk of damage to the associated equipment. Reliability Standard PRC-025-2 improves upon currently-effective Reliability Standard PRC-025-1 by addressing certain relay setting application issues and by clarifying certain terminology and references. NERC requested that the Commission approve the Reliability Standard and find that the proposed standard is just, reasonable, not unduly discriminatory or preferential, and in the public interest. NERC also requested that the Commission approve: (i) the associated Implementation Plan; (ii) the associated Violation Risk Factors (VRFs) and Violation Severity Levels (VSLs), which remain unchanged from PRC-025-1; and (iii) the retirement of currently-effective Reliability Standard PRC-025-1.
