been addressed in a filing to the Commission prior to Advice Letter 5046-E (2017), which is the subject of this Resolution. Caltrain Peninsula Corridor Electrification Project This Project is part of the larger Caltrain Modernization Program, which will electrify and upgrade the performance, efficiency, capacity, safety, and reliability of the Caltrain commuter rail service. PG&E plans to interconnect with Caltrain Project electrical infrastructure at two sites: Site 1 (San Francisco) and Site 3 (San Jose). Final system testing of the completed Caltrain infrastructure and upgraded PG&E infrastructure along the rail alignment is planned to begin by 2021 (Caltrain November 2017 Fact Sheet). Project information is provided at: Interconnection Work Filings (Caltrain Project) To date, the Commission has adopted two Resolutions approving contractual agreements between PG&E and Caltrain: Resolution E-4811 (December 15, 2016) and Resolution E-4830 (April 27, 2017). The Resolutions approved agreements related to the interconnection of PG&E facilities necessary to provide power to the Caltrain Project. Cost allocation to PG&E ratepayers was not addressed in either Resolution because Caltrain agreed to pay 100 percent of costs incurred by PG&E for all work associated with those agreements. The first Resolution approved a Master Agreement with PG&E for interconnection work and Supplement #1 to the Master Agreement. Supplement #2 and Supplement #5 to the Master Agreement were approved by the second Resolution. Supplement #3, which is the subject of this Resolution, describes preliminary cost allocation principles to be applied to the Caltrain Project—the same principles that will apply to the CHSRA Project. Supplement #4 (not yet filed) will cover final design, engineering, and construction of upgrades to the two PG&E substations that are required to power the Caltrain Project. At its February 1, 2017 meeting, the Peninsula Corridor Joint Powers Board of Directors authorized execution of Supplement #4 to the Master Agreement, but it has not yet been finalized and filed with the Commission.
interconnection agreement with Caltrain. All of the filed interconnection agreements had already been executed by the parties, and PG&E completed a series of complex technical studies and planning activities required by those interconnection agreements that were paid in full by CHSRA and Caltrain. Specific costs are identified in several of the interconnection agreements filed for the CHSRA Project but will be paid in full by CHSRA. Agreements HSR 10-10, HSR 14-37, HSR 14-37a1, HSR 14-37a2, and HSR 16-56 between PG&E and CHSRA are summarized in Table 1. The first four agreements identified are for the completion of technical reports to identify the scopes of work required for PG&E to provide electrical power to the CHSRA Project. Table 1.
