WATER ENERGY LIFE CITY OF RIVERSIDE lag PUBLIC UTILITIES RIVERSIDE PUBLIC UTILITIES Board Memorandum BOARD OF PUBLIC UTILITIES DATE: NOVEMBER 13, 2023 SUBJECT: ORANGECREST SUBSTATION TO SPRINGS SUBSTATION FIBER OPTIC CABLE UPGRADE; WORK ORDER NO. 2224356 IN THE AMOUNT OF $649,000 ISSUE: Consider approving the capital expenditure for Work Order No. 2224356 in the amount of $649,000 for the Orangecrest Substation to Springs Substation Fiber Optic Cable Upgrade Project. RECOMMENDATION: That the Board of Public Utilities approve the capital expenditure for Work Order No. 2224356 in the amount of $649,000 for the Orangecrest Substation to Springs Substation Fiber Optic Cable Upgrade Project. BACKGROUND: Riverside Public Utilities (RPU) operates an advanced broadband fiber optic cable network that facilitates secure and efficient communication between electrical substations and the utility operations center. This network is designed primarily to support Operational Technology (OT) applications, including critical systems such as Supervisory Control and Data Acquisition (SCADA), radio communications, and teleprotection. These applications are fundamental in sustaining the seamless functioning of our utility grid, requiring a network that can guarantee high-speed and real-time data transmission. The fiber network offers a high bandwidth capacity and low latency, which are instrumental in accommodating the complex data transmission requirements of OT applications. In addition, fiber optics are inherently secure, offering immunity to electromagnetic interference and resistance to many types of eavesdropping attacks prevalent in traditional copper lines. Currently, the network includes a 12 -strand fiber optic aerial cable and underground fiber cable that connects the Orangecrest Substation to the Springs Substation, which was installed in 1994. The fiber optic cable route between these two substations consists of three segments: Segment One: This segment, measuring 9,300 feet, connects the Orangecrest Substation to the Mission Grove cross -connect. The fiber optic cable is mounted along an existing overhead pole line composed of wooden and steel poles.
