Under section 215 of the Federal Power Act, the Commission approved four revised regional Reliability Standards developed by the Western Electricity Coordinating Council and approved by the North American Electric Reliability Corporation, which the Commission has certified as the Electric Reliability Organization responsible for developing and enforcing mandatory Reliability Standards. These regional Reliability Standards have been designated by the Western Electricity Coordinating Council as FAC-501-WECC-1 - Transmission Maintenance, PRC-004-WECC-1 - Protection System and Remedial Action Scheme Misoperation, VAR-002-WECC-1 - Automatic Voltage Regulators, and VAR-501-WECC-1 - Power System Stabilizer. Reliability Standard FAC-501-WECC-1 addresses transmission maintenance for specified transmission paths in the Western Interconnection. Reliability Standard PRC-004-WECC-1 addresses the analysis of misoperations that occur on transmission and generation protection systems and remedial action schemes in the Western Interconnection. Reliability Standard VAR-002-WECC-1 is meant to ensure that automatic voltage regulators remain in service on synchronous generators and condensers in the Western Interconnection. Reliability Standard VAR-501-WECC-1 is meant to ensure that power system stabilizers remain in service on synchronous generators in the Western Interconnection. In addition, the Commission approved five new regional definitions applicable within the Western Interconnection, (Docket No. RM09-09-000).
