W X 7 E R E N E R G Y L I € f RIVERSIDE PUBLIC UTILITIES Board Memorandum PUBLIC UTILITIES BOARD OF PUBLIC UTILITIES DATE: April B, 2012 ITEM NO: B SUBJECT: UPGRADE OF THE DATAICOMMUNICATION LINK AT SOUTHERN CALIFORNIA EDISON'S VISTA SUBSTATION AND AT OTHER RIVERSIDE PUBLIC UTILITIES FACILITIES ISSUE: That the Board of Public Utilities consider approval of the Interconnection Facilities Agreement between the City of Riverside and Southern California Edison Company to facilitate the upgrade of the data/communication link at Vista Substation and at other Riverside Public Utilities (RPU)facilities. RECOMMENDATIONS. That the Board of Public Utilities: 1. Approve the Interconnection Facilities Agreement (Agreement) between City of Riverside and Southern California Edison Company; 2. Authorize the City Manager, or his designee, to execute the Agreement and take the necessary actions to implement the Agreement; and 3. Approve the Work Order No. 0805934 in the amount of$400,000. BACKGROUND: Southern California Edison Company {SCE} provides power transmission services to the City of Riverside from SCE's Vista Substation located just north of Riverside in the City of Grand Terrace. Vista Substation's remote terminal unit (or RTU) is providing essential data to RPU's dispatch center located at the Utility Operations Center (UOC). The RTU communicates the information through an existing four-wire modem over the General Electric Company's Junglemux based Synchronous Optical Network (SONET)system. RPU has recently completed some upgrades to the RPU owned and controlled Supervisory Control and Data Acquisition(SCADA)system to better manage and operate RPU Energy Delivery assets. RPU's new SCADA system communicates through state-of-the-art technology (ethernet based, DNP 3.0 protocol). Currently, SCE does not transmit data to RPU in this manner, and the two communication systems are incompatible. RPU is maintaining a part of the old technology at our dispatch center located at the UOC to receive this data from Vista. RPU has added a Backup Dispatch Operation Center at Riverside Energy Resource Center for use in the event of an emergency. The data from SCE Vista substation is not available to the SCADA system at the backup dispatch center due to the limitations of the old technology. The data furnished to RPU from SCE's Vista Substation utilizes old technology and must be upgraded in order to provide RPU with critical system information to support normal operations. The upgrades contemplated underthe Agreement will also provide additional data needed from the SCE transmission lines that serve the RPU energy delivery system.
