NJ A T T R F N F R G Y L RIVERSIDE PUBLIC UTILITIES .�19& Board Memorandum P U B L I C U T I L I T I E S BOARD OF PUBLIC UTILITIES DATE: AUGUST 12, 2019 ITEM NO: 5 SUBJECT: PLAZA SUBSTATION 4kV TO 12kV CONVERSION OF CIRCUIT441 —WORK ORDER NO. 1708708 FOR A TOTAL CAPITAL EXPENDITURE OF $2,038,000 ISSUE: Approve Work Order No. 1708708 for a total capital expenditure of $2,038,000 for the Plaza Substation 4kV to 12kV Conversion of Circuit 441 Project. RECOMMENDATION: That the Board of Public Utilities approve Work Order No. 1708708 for a total capital expenditure of $2,038,000 for the Plaza Substation 4kV to 12kV Conversion of Circuit 441 Project. BACKGROUND: The Electric System Master Plan (ESMP) recommends the conversion of all remaining 4kV to 12kV distribution circuits to improve system capacity and reliability. This project will upgrade existing 4kV electrical distribution facilities to 12kV and provide additional electrical field ties to existing 12kV circuits to improve system reliability and decrease outage restoration time for area customers. Intermittent electric service disruptions will be coordinated during construction and advanced outage notifications will be issued to minimize the impact to customers. DISCUSSION: The proposed project will upgrade electric distribution facilities north of Central Avenue, south of Jurupa Avenue, east of Magnolia Avenue, and west of Streeter Avenue. The scope of work includes the replacement and installation of 88 wooden poles, 39 transformers, and related overhead distribution facilities. The project will convert approximately 16,500 linear feet of aging 4kV distribution facilities with new 12kV electric distribution facilities, which will improve system reliability and safety, improve power quality and electric service to customers in the area, and replace aging infrastructure that is beyond its useful life. Replacement of 4kV to 12kV and related distribution facilities is identified as part of the Utility 2.0 Electric Infrastructure Road Map. Electrical work will be completed by RPU field forces; no civil work is required as part of this project. RPU engineering staff performed the design to eliminate any negative visual impacts to the project and surrounding area, with sensitivity to the existing neighborhood, and within City Planning guidelines for the designated area of the project.
