5 transmit the project power to market.2 Under this test,the line leading from the project ceases to be a primary line at the point it is no longer used solely to transmit power from the project to the interconnected grid.3 The South Line does not constitute a primary line as that term is used in 16 U.S.C. § 796(11),because the South Line is no longer used solely to transmit power from the Jackson Project but is part of the PUD's loop transmission system. It is used to transmit power from BPA and other sources in addition to the Jackson Project,which allows the PUD to service the Sultan, Woods Creek,West Monroe, and Goldbar substations and provide backup capability to other PUD substations served by the Jackson Loop. Another use of the South Line is to prevent disruption of service in the event of an outage on the Jackson Loop. If such an outage were to occur,only one circuit (either the North Line or the South Line)would trip, allowing part of the transmission load to remain operational. This circuit configuration allows the load connected to the faulted circuit to be isolated and transferred to the other circuit. Additionally,the South Line is also used to reduce outage exposure in the event of a BPA Snohomish bus outage.
