1 Fast Track Process This presentation is a tool to supplement the FERC approved Generator Interconnection Procedures (GIP) found in Attachment I of PG&E s Wholesale Distribution Tariff (WDT) and Appendix Y of CAISO s Tariff. It is not intended to replace the tariff. PG&E advises customers to become familiar with the applicable tariff and use this tool as a supplement. Generation Interconnection Services October 27,

2 Overview of Wholesale Generation Interconnection Process Transmission Interconnections Governed by California Independent System Operator Corporation (CAISO) Tariff PG&E s transmission interconnections are for 60 kv and higher All applications must be submitted to the CAISO These slides are pursuant to CAISO Tariff Appendix Y which is subject to the CAISO Distribution Interconnections Governed by PG&E s Wholesale Distribution Tariff (WDT) PG&E s distribution voltage level is defined as facilities operating below 60 kv All applications must be submitted to PG&E These slides are pursuant to WDT Attachment I 1

15 Appendix: Capital Improvement Terms Interconnection Facilities The Distribution Provider's Interconnection Facilities and the Interconnection Customer's Interconnection Facilities. Collectively, Interconnection Facilities include all facilities and equipment between the GF and the Point of Interconnection, including any modification, additions or upgrades that are necessary to physically and electrically interconnect the GF to the Distribution Provider's Distribution System. Interconnection Facilities are sole use facilities and shall not include Distribution Upgrades or Network Upgrades. Distribution Upgrades The additions, modifications, and upgrades to the Distribution Provider's Distribution System at or beyond the Point of Interconnection to facilitate interconnection of the GF and render the service necessary to effect the Interconnection Customer's wholesale sale of electricity in interstate commerce. Distribution Upgrades do not include Interconnection Facilities. Network Upgrades Additions, modifications, and upgrades to the Distribution Provider's Transmission System required at or beyond the point at which the Distribution System connects to the Distribution Provider s Transmission System to accommodate the interconnection of the GF to the Distribution Provider s Transmission System. Network Upgrades do not include Distribution Upgrades. 14

16 Appendix: Key Terms Point of Interconnection The point where the Interconnection Facilities connect with the Distribution Provider's Distribution System. Interconnection Facilities The Distribution Provider's Interconnection Facilities and the Interconnection Customer's Interconnection Facilities. Collectively, Interconnection Facilities include all facilities and equipment between the GF and the Point of Interconnection, including any modification, additions or upgrades that are necessary to physically and electrically interconnect the GF to the Distribution Provider's Distribution System. Interconnection Facilities are sole use facilities and shall not include Distribution Upgrades or Network Upgrades. Distribution System Those non-iso transmission and distribution facilities owned, controlled and operated by the Distribution Provider that are used to provide distribution service under the Tariff, which facilities and equipment are used to transmit electricity to ultimate usage points such as homes and industries directly from nearby generators or from interchanges with higher voltage transmission networks which transport bulk power over longer distances. The voltage levels at which Distribution Systems operate differ among areas. Upgrades The required additions and modifications to the Distribution Provider's Transmission System and Distribution System at or beyond the Point of Interconnection. Upgrades may be Network Upgrades or Distribution Upgrades. Upgrades do not include Interconnection Facilities. 15
