17. Borah West Revised January 2013 Accepted Rating Existing Rating Other Location: Definition: Transfer Limit: Critical Disturbance that limits the transfer capability: When: System Conditions: Study Criteria: Remedial Actions Required: Formal Operating Procedure: Allocation: Southeast Idaho Sum of the flows on the following lines: Line Kinport-Midpoint 345 kV Borah-Adelaide-Midpoint #1 345 kV Borah-Adelaide #2 345 kV Borah-Hunt 230 kV AmFalls-Plst Vly-Minidoka 138 kV Metered End Kinport Borah Borah Borah American Falls East to West: 2557 MW West to East: 1600 MW (“Other” Rating: Rating established following NERC MOD-029-1a_R2.2 requirement) The Borah West transfer capacity is limited by the double line (N-2) loss of the Kinport-Midpoint 345 kV and the Borah-Adelaide-Midpoint #1 345 kV lines. The 2557 MW Borah West rating was established in the Phase II comprehensive progress report, which was issued September 10, 2002. The Borah West Uprate project was granted Phase III status on March 24, 2003. The Borah West Uprate project was placed in-service in June 2007. The Borah West transfer rating was determined with simultaneous heavy transfers on series path (Path C south to north, and Bridger West) consistent with the transfers of eastern thermal resources to the west. NERC/WECC Reliability Criteria for Transmission System Planning The loss of two Borah West lines simultaneously or one element initially outof-service and loss of another line could initiate one or more of the following Remedial Actions: Tripping of one/two Jim Bridger unit(s). Bypassing either or both Midpoint and/or Burns 500 kV Series Capacitors. Insertion of one or more of the Kinport, Borah, and Midpoint 345 kV Shunt Capacitors For PDCI south to north operation, a nomogram exists for flows on the PDCI, COI, Borah West and available load dropping in the Northwest. California ISO T-122 (West of Borah versus Path 15 nomogram). Idaho Power Company (IPC) owns the Borah West transfer path and capacity is owned by Idaho Power Company (IPC). IPC has long term agreements to provide transmission services on this path to PacifiCorp for up to 1600 MW. PART VI Item 1-46
Revised January 2010 Interaction w/Other Transfer Paths: Contact Person: There is a known interaction for south to north transfers on PDCI and COI and Borah West. Also, there is a known interaction for high south to north transfers on Path 15 and Path 26 (under outage conditions) and high east-towest transfers on Borah West that requires operation based on a nomogram.
