Version One Regional Reliability Standard for Transmission Operations

Under section 215(d)(2) of the Federal Power Act, the Federal Energy Regulatory Commission approves regional Reliability Standard TOP-007-WECC-1 (System Operating Limits) developed by the Western Electric Coordinating Council (WECC) and submitted to the Commission for approval by the North American Electric Reliability Corporation. The primary purpose of this regional Reliability Standard is to ensure that actual flows and associated scheduled flows on major WECC transfer paths do not exceed system operating limits for more than 30 minutes. The Commission also approves the retirement of WECC regional Reliability Standard TOP-STD-007-0, which is replaced by the regional Reliability Standard approved in this Final Rule. The Commission also directs WECC to modify the associated violation risk factors and violation severity levels.
