15. Midway - Los Banos Revised January 2011 Accepted Rating Existing Rating Other Location: Definition: Transfer Limit: Critical Disturbance that limits the transfer capability: Between central and southern California within the PG&E system and south of Los Banos substation (PG&E internal Path 15). Measured at Los Banos for all 500 kV lines and at Gates for all 230 kV lines for both north-to-south and south-to-north flows: Midway-Los Banos 500 kV line (at Los Banos) Gates-Los Banos # 1 and #3 500 kV lines (at Los Banos) Gates-Panoche #1 & #2 230 kV lines (at Gates) Gates-Gregg 230 kV line (at Gates) Gates-McCall 230 kV line (at Gates) The transfer limit ranges from 2000-3265 MW from north to south. The transfer limit ranges from 4800-5400 MW from south to north. From north to south: Midway-Gates and Midway-Los Banos 500 kV double line outage. Double Palo Verde unit outage. Los Banos-Tesla and Los Banos-Tracy 500 kV double line outage. From south to north: Double line 500 kV outages between Tesla and Midway. When: The 3265 MW north-to-south rating was established in the August 5, 2002 Path 15 Upgrade north-to-south Project Comprehensive Progress Report. Phase III Status granted on October 23, 2003. The 5400 MW south-to-north rating was established in the September 18, 2001 Path 15 Upgrade Project Comprehensive Progress Report. A letter from the PCC chair indicating the Phase II report was accepted and granting Phase III status was distributed on February 5, 2003. System Conditions: Study Criteria: Remedial Actions Required: Formal Operating Procedure: Allocation: Interaction w/Other Transfer Paths: The north-to-south path rating was based on north-to-south transfers under heavy summer (high temperature) operating conditions. The south-to-north path rating was based on south-to-north transfers under light winter operating conditions. NERC/WECC Planning Standards. Remedial actions are employed on an as needed basis for double line outages between Tesla and Midway. CISO T-122 and PG&E O-51 operating procedures which are periodically updated. PG&E, SCE, SDGE, CDWR, and various new owners. For high north-to-south flows on Path 15 and high north-to-south flows on COI and/or PDCI it is necessary to operate based on a nomogram. Path 15 north-to-south transfer limit can be significantly less with high generation levels in the Midway area because of Path 26 limitations. For high south-to-north flows on Path 15 and high east-to-west flows on West of Borah it is necessary to operate based on a nomogram. PART VI Item 1-40
