Revised January 2013 75. Hemingway – Summer Lake PART VI Item 1-188
Revised January 2013 75. Hemingway – Summer Lake Accepted Rating Existing Rating Other Location: Definition: Transfer Limit: Critical Disturbance that limits the transfer capability: When: Southwest Idaho and eastern Oregon Hemingway-Summer Lake 500 kV metered at the Hemingway 500 kV. Note: The path is also within Path 14 Idaho-Northwest. East to West: 1500 MW West to East: 550 MW East to West: Thermal overload on the Walla Walla 230 kV series capacitor following the loss of the Hemmingway – Summer Lake 500 kV line. West to East: The thermal overload of the Lolo-Oxbow 230 kV line is the limiting condition for an outage of the Hemingway-Summer Lake 500 kV line. The path is also limited by a reactive margin in the northwest for a double Palo Verde unit outage. The east to west rating is limited by thermal ratings of Midpoint 345/500 kV transformer and series capacitor in the line. It was established along with the 2400 MW east to west rating of Idaho to Northwest path in August, 1989 with the publication of Idaho Power Company to Pacific Northwest Intertie Capacity Study. The WECC Notification Procedures for Changes in Facility Rating and/or Operating Procedures was followed. The east to west rating was conducted jointly by: Bonneville Power Administration (BPA) Idaho Power Company (IPCO) PacifiCorp (PAC) Avista Corp. (AVA) The 550 west to east rating is based on path studies completed in 2009. Phase 3 status was granted on July 22, 2009 Midpoint-Summer Lake was redefined to Hemingway-Summer Lake in 2010 due to addition of the Hemingway 500/230 kV substation. PART VI Item 1-189
