Appendix D - BC Hydro - Transmission

Transmission Provider will conduct appropriate studies to determine the impact onTransmission Provider Transmission System based on the actual data submitted pursuantto this Article 24.3. The Interconnection Customer shall not begin Trial Operation untilsuch studies are completed.24.4 Information Supplementation. Prior to the Operation Date, the Parties shallsupplement their information submissions described above in this Article 24. 24 with anyand all "as-built" Large Generating Facility information or "as-tested" performanceinformation that differs from the initial submissions or, alternatively, writtenconfirmation that no such differences exist. The Interconnection Customer shall conducttests on the Large Generating Facility as required by Good Utility Practice such as anopen circuit “step voltage” test on the Large Generating Facility to verify properoperation of the Large Generating Facility’s automatic voltage regulator.Unless otherwise agreed, the test conditions shall include: (1) Large Generating Facilityat synchronous speed; (2) automatic voltage regulator on and in voltage control mode;and (3) a five percent change in Large Generating Facility terminal voltage initiated by achange in the voltage regulators reference voltage. Interconnection Customer shallprovide validated test recordings showing the responses of Large Generating Facilityterminal and field voltages. In the event that direct recordings of these voltages isimpractical, recordings of other voltages or currents that mirror the response of the LargeGenerating Facility's terminal or field voltage are acceptable if information necessary totranslate these alternate quantities to actual Large Generating Facility terminal or fieldvoltages is provided. Large Generating Facility testing shall be conducted and resultsprovided to Transmission Provider for each individual generating unit in a station.Subsequent to the Commercial Operation Date, Interconnection Customer shall provideTransmission Provider any information changes due to equipment replacement, repair, oradjustment. Transmission Provider shall provide Interconnection Customer anyinformation changes due to equipment replacement, repair or adjustment in the directlyconnected substation or any adjacent Transmission Provider-owned substation that mayaffect Interconnection Customer's Interconnection Facilities equipment ratings, protectionor operating requirements. The Parties shall provide such information no later than thirty(30) Calendar Days after the date of the equipment replacement, repair or adjustment.Article 25Article 25. .
