Revised January 2013 System Conditions: Study Criteria: Remedial Actions Required: Formal Operating Procedure: Allocation: Interaction w/Other Transfer Paths: North to South: The two Custer-Ingledow tielines can transmit 2850 MW from Canada to the Northwest when BC Hydro’s load (Canada) is between approximately 40% and 70% of its annual peak load. South to North: Restrictions occur during winter peak demand periods due to thermal and voltage stability concerns in the Northwest and British Columbia. However, predominant transfers occur during spring months when voltage stability limitations are not a concern in northwest Washington. Restrictions also occur when Puget Sound area generation level is low in both heavy summer and winter load conditions. 1. “BCH System Operating Limits Methodology”, SPA Report No. SPA2008-02, 15 December 2009. 2. WECC Regional Criteria TPL-(001 thru 004) – WECC-1-CR ─ System Performance Criteria North to South: The 230 kV tie lines are directly transfer tripped after loss of both 500 kV Ingledow-Custer ties when the North to South total transfer exceeds 400 MW, thus separating the Northwest from Canada. The maximum amount of generator tripping in Canada (B.C. Hydro) is about 110% of the scheduled export from Canada to the Northwest. Reactive power equipment switching scheme is used in BC Hydro (Canada) to control over voltages for loss of both 500 kV Ingledow – Custer ties when the transfer on the Ingledow-Custer tie lines is between 2000 and 2850 MW. Certain Northwest Washington area contingencies require generation tripping in Canada when flows are above 800 MW. This generation trip is never more than 1850 MW. Puget Sound Energy generation tripping is also armed at Whitehorn and Fredonia for some of these contingencies. South to North: The 230 kV tielines are directly tripped after outages of both 500 kV Ingledow-Custer ties when the South to North total transfer exceeds 400 MW, thus separating the Northwest from Canada. In addition, the BCH – AB tie lines will be tripped open after loss of both 500 kV Ingledow-Custer ties when BCH net importing is high B.C. Hydro’s System Operating Order #7T-18 “Custer-Ingledow 500 kV Interconnection,” and #7T-64 “BC HYDRO TRANSFER LIMITs” BPA Dispatcher Standing Order #320 “Operation of the Northern Intertie” and Standing Order #323 “Bellingham Area-Intalco Load Tripping.” North to South: All of the capacity is allocated to B. C. Hydro, BPA, and PSE. South to North: All of the capacity is allocated to B.C. Hydro, BPA, and PSE. North to South: For the Ingledow-Custer intertie 2850 MW accepted rating, there is a potential interaction with the Raver-Paul loading. South to North: For the Ingledow-Custer intertie 2750 MW accepted rating there is a potential interaction with PDCI N-S and COI N-S transfers at higher levels. PART VI Item 1-10
