BACKGROUND INFORMATION: The Electric Utility Department (EUD) has planned to build a fifth substation at the western area of the City limits. The substation site has been in Lodi's electric facilities plan for some time and was purchased in 2003 as land was available. The working name for the planned facility is the Westside Substation. This substation will be required for continued reliable service to new and existing customers. The requestfor proposal will cover the preliminary engineering and design activities on the new Westside Substation. The initial task list includes the following: 1. Soil resistivitytest and geotechnical study 2. Preliminary ground grid design as per IEEE Standard 80 3. Ground potential rise (GPR) study 4. Preparation of preliminary substation layout, design criteria, and cost/benefit analysis 5. Engineering and design of perimeter block wall fence and landscape Items 1 and 2 are needed to complete the GPR study, which will be provided to the telephone and communication companies for ground fault protection. Item 4 will be the basis for developing the final substation facility design. Final design, permitting, and construction activities would follow the completion of item 5. The location of the new Westside Substation provides a strategic site for power system interconnection within the City of Lodi boundaries. The existing 60kV loop will terminate in the substation. The other planned 60kV line from the Industrial Substation traversing via Harney Lane through Lower Sacramento Road will also terminate in the substation. On June 3, 2009 as per Resolution No. 2009-74, the City Council awarded the preparation of Lodi West 60kV Power Line Project environmental impact report to InSite Environmental, Inc. A double -circuit, 60kV transmission line, once completed, will connect to the Westside Substation. The substation facility will provide load serving capacity to planned development projects like Westside Project, Southwest Gateway Project and other identified annexation areas with a total estimated load of approximately 16MW. The Westside substation will be used to reduce existing loads from the Henning Substation.
