PG&E Northern San Joaquin Power Connect Update

BACKGROUND INFORMATION:
Receive PG&E's Northern San Joaquin Power Connect update.
The Pacific Gas and Electric Company (PG&E) has prepared a
presentation to update Lodi's City Council on the status of its
Northern San Joaquin Power Connect project.
This project will solve multiple transmission system reliability and overload issues as identified by the
California Independent System Operator (ISO) for the northern San Joaquin County 230 kV grid. In
addition, it provides an opportunity for the City of Lodi to improve its electric service for its customers in
terms of reliability, power quality, and capacity to serve future new developments.
The project was approved by the ISO's Board of Directors during its 2012-2013 Transmission Planning
Process (TPP). In the ISO's 2016-2017 TPP the Board placed this project on hold for further review.
City staff has continued to be engaged with PG&E and the ISO to ensure the future of this project with
the electric utility's grid intertie will meet the energy needs of the community.

2016-2017 ISO Transmission Plan January 31, 2017
In addition, the ISO's review indicates that the following projects require further evaluation in
future planning cycles. Although mitigation solutions continue to be needed for some of the issues
addressed by these projects, the ISO must further evaluate the uncertainties in variations in load
forecast and other parameters and reassess the scope of these projects.
The following four projects are in the late stages of design, siting, and permitting, and continuing
the design, siting and permitting activities will assist in the review. However, the ISO is
recommending that the project sponsors do not proceed with filings for permitting and certificates
of public convenience and necessity for the following projects until the ISO completes the reviews:
• Midway -Andrew 230 kV Project
• Spring Substation
• Wheeler Ridge Junction Substation
• Lockeford-Lodi Area 230 kV Development
For the following projects, all development activities are recommended to be put on hold until a
review is complete.
• Gates -Gregg 230 kV Line (see additional information in section 2.5.9.1)
• Watsonville Voltage Conversion
• Atlantic -Placer 115 kV Line
• Vaca -Davis Voltage Conversion Project
• Northern Fresno 115 kV Area Reinforcement
• South of San Mateo Capacity Increase
• Evergreen-Mabury Conversion to 115 kV
• New Bridgeville Garberville No. 2 115 kV Line
• Cottonwood -Red Bluff No. 2 60 kV Line Project and Red Bluff Area 230 kV Substation
Project
• Kern PP 115 kV Area Reinforcement
• Wheeler Ridge-Weedpatch 70 kV Line Reconductor
In future planning cycles the ISO may again reassess previously approved transmission projects
to determine if there are material changes in the assumptions supporting the need for previously
approved projects.
2.5.9,1 Gates -Gregg -230 kV Line Project
The ISO approved the Gates -Gregg 230 kV Line project in the 2012-2013 transmission planning
process as a Reliability Driven Project with renewable integration benefits. The reliability -driven
need for the line was to increase the pumping opportunities at the Helms pumped
storage/generation facility to ensure there would be adequate water available when the
generation was called upon to support local area loads. The 2012-2013 transmission planning
process identified that the availability of pumping would begin to decrease in the 2023 timeframe
with inadequate pumping opportunities to provide sufficient water for generation to meet reliability
needs in Fresno local area by the 2029 timeframe.
In this planning cycle, the ISO reassessed the need for the Gates -Gregg 230kV line using the
assumptions in the 2016-2017 transmission planning process based upon the CEC 2015 IEPR
California ISO/MID 103
