Revised November 2007 29. Intermountain - Gonder 230 kV Accepted Rating Existing Rating Other Location: Definition: Transfer Limit: Critical Disturbance that limits the transfer capability: Transmission line from Intermountain Power Facility (IPF) at Delta, Utah to Gonder station in eastern central Nevada A 144-mile 230 kV transmission line from the 230 kV IPF station to the Mt. Wheeler Power Cooperative’s Gonder 230 kV station. The IPF 230 kV station is connected to the IPF 345 kV station through a 300 MVA regulating transformer. The IPF 345 and 230 kV stations are in the Los Angeles Department of Water and Power (LADWP) control area, while the Gonder 230 kV station is in the Sierra Pacific Power Company’s control area. East to West: 200 MW (non-simultaneous) Studies to determine the simultaneous rating of this line with the Pavant- Gonder 230 kV line are presently on-going. The non-simultaneous rating is based on the rule-of-thumb criterion of 30 degree power angle difference between the sending and the receiving end, and on N-0 load flow studies. When: The 200 MW bidirectional non-simultaneous rating was established in 1987, when the IPF was first put into service. This rating has been documented in the WECC Operations Committee’s Non-Simultaneous Transfer Capability Diagram as well as in the NERC Form OE-411, Item 5A reportings. System Conditions: Study Criteria: Remedial Actions Required: Formal Operating Procedure: Allocation: Interaction w/Other Transfer Paths: The non-simultaneous rating is based on the rule-of-thumb criterion of 30 degree power angle difference between the sending and the receiving end, and on N-0 load flow studies. WECC Reliability Criteria for System Design. (The applicable WECC reliability criteria at that time.) For disturbances where both of the IPF-Mona 345 kV lines are tripped, a transfer trip protection trips the IPF-Gonder 230 kV line. There is an established energization/synchronization procedure for the line to control overvoltage conditions on the line. The IPF 230/345 kV regulating transformer (ULTC) is under the LADWP SCADA system. The following utilities have entitlements on this line: LDWP, Anaheim, Riverside, Pasadena, Burbank and Glendale. At the maximum flow conditions, the transfer capability of the line is sensitive to the flows on the Pavant-Gonder 230 kV line. Simultaneous flow capability of these two lines at the Gonder station cut-plane is presently under going a study. PART VI Item 1-82
