20. Path C (Pre Gateway) Revised January 2013 Accepted Rating Existing Rating Other Location: Definition: Transfer Limit: Critical Disturbance that limits the transfer capability: Northern Utah/Southern Idaho Sum of the flows on the following transmission lines: Line Malad-American Falls* 138 kV Ben Lomond-Populus* #1 345 kV Ben Lomond-Populus* #2 345 kV Terminal-Populus * 345 kV Treasureton-SunBeam-Brady* 345 kV FishCreek-Goshen* 161 kV Threemile Knoll 138/345 * kV transformer Threemile Knoll 138*/115 kV transformer (Future) North to South: 1600 MW (nominal) South to North: 1250 MW (nominal) Operating limits are based on System Operating Limit (SOL) studies. Southbound: Post disturbance voltages on Path 18 limit southbound capacity to 1600 MW following an N-2 Path 19 outage which causes two Bridger units to trip due to Bridger RAS operation. Northbound: Post disturbance flows following N-1 or N-2 outages on the remaining line west of Populus limit the Northbound capacity to 1250 MW or less based on a simultaneous nomogram (Figure 1) with Bridger West. Up to two Bridger units may trip due to Bridger RAS operation to reduce Populus west flow. When: Phase 3 status granted November 20, 2008 System Conditions: Study Criteria: Remedial Actions Required: Formal Operating Procedure: Northbound capacity is determined under light load conditions when thermal resources in Utah are being transferred to the NW, and Southbound capacity is determined under heavy summer loading conditions. Due to the interaction with the Bridger West Path, a nomogram between Path C (Northbound) and Bridger West has been established. (See Figure 1) • Steady state pre disturbance voltages between .95 p.u. and 1.05 p.u. • Post-disturbance voltages between .90 p.u. and 1.10 p.u. • Post-disturbance line loadings less than “emergency ratings.” • First-swing transient voltage dips not to exceed .80 p.u. Bridger RAS operation may trip up to two units as discussed above. Yes Allocation: 100% PacifiCorp PART VI Item 1-56
