RIVERSIDE PUBLIC UTILITIES Board Memorandum BOARD OF PUBLIC UTILITIES DATE: DECEMBER 13, 2021 SUBJECT: BID NO. SUB-851 TELEPROTECTION SUBSTATION AUTOMATION INFRASTRUCTURE UPGRADE PROJECT WITH ONESOURCE DISTRIBUTORS OF OCEANSIDE, CALIFORNIA, IN THE AMOUNT OF $458,525.38 WORK ORDER 2202600 IN THE AMOUNT OF $544,378 ISSUES: Consider the award of Bid No. SUB-851 for teleprotection equipment to OneSource Distributors, of Oceanside, California, in the amount of $458,525.38 and approve the capital expenditure for Work Order No. 2202600 in the amount of $544,378 for the Teleprotection and Substation Automation Infrastructure Upgrade Project. RECOMMENDATIONS: That the Board of Public Utilities: 1. Award Bid No. Sub-851 for Teleprotection and Substation Automation Infrastructure Upgrade Project to OneSource Distributors, of Oceanside, California, in the amount of $458,525.38; and 2. Approve Work Order No. 2202600 in the amount of $544,378. BACKGROUND: Teleprotection is a key technology for protecting the integrity of sub-transmission lines and the voltage stability of the electric grid. Teleprotection devices use communication channels to exchange information between substation transmission relays such as pilot and distance relays. The transmission relays use this information to detect faults on transmission lines and clear faults at very high speed, minimizing system damage and maintaining system stability. Riverside Public Utilities (RPU) currently utilizes a legacy Synchronous Optical Network (SONET) as a platform for teleprotection. Although this system was installed in the early 1990s, SONET has been very reliable technology. It provides deterministic channel behavior, which is critical for teleprotection applications. However, the SONET platform has reached its end of life and will soon no longer be supported by the manufacturer, which causes challenges maintaining the existing aging system. To minimize any disruption of current electric utility operations, RPU is planning to upgrade the existing teleprotection system with a newer platform.
