W A T E R E N E R G Y L I F E El W& RIVERSIDE PUBLIC UTILITIES Board Memorandum P U 8 L I L U f I L I T I F 5 BOARD OF PUBLIC UTILITIES DATE: October 7, 2011 ITEM NO: 6 SUBJECT: REMOTE INTELLIGENT GATEWAY AND CALIFORNIA INDEPENDENT SYSTEM OPERATOR METERING AGREEMENT WITH TRIMARK ASSOCIATES, INC. ISSUE: That the Board of Public Utilities consider approval of an Agreement with Trimark Associates, Inc. for: (i) maintenance of the California Independent System Operator (CAISO) meters at the Riverside Energy Resource Center(RERC), Springs Generating Station and Clea rwater Cogenerati on Facility;and(ii) Remote Intelligent Gateway(RIG)installation and maintenance necessary for generating station communications with the CA[SO. RECOMMENDATION: That the Board of Public Utilities approve an Agreement with Trimark Associates, Inc., of Folsom, California, in an amount not-to-exceed $93,849(including a one-time cost of$82,104 for RIG Replacement Costs and an annual cost of$11,745 for annual service) for Fiscal Year 2011-12. BACKGROUND: The CAISO requires onsite continuous production metering and telemetry of generating units. This equipment ensures accurate revenue accounting and operational visibility of those units for the CAISO. Due to the criticality of uninterrupted operation and the need for formal equipment certifications, Riverside Public Utilities (RPU) sub-contracts this service to a CAISO approved vendor. The Springs Generating Station was commissioned in June 2002 and is still operating on the original RIG telemetry equipment installed at that time. RERC Units 1 and 2, commissioned in July 2006, are also operating with this identical RIG system. To accommodate the timely commissioning of RERC Units 3 and 4, the units were added to the existing RIG facility equipment with the understanding that the hardware and software would need to be replaced in order to enhance connection reliability to the CAISO. The Clearwater Cogeneration Facility, commissioned in March 2005, has experienced ongoing telemetry interruptions related to the RIG software and equipment. The existing software and equipment are no longer supported, making permanent repairs difficult and unreliable. RPU staff solicited proposals to replace the existing RIG equipmentwith newstandardized RIG equipment for all three (3) generation facilities from CAISO approved vendors. After evaluating the proposals, staff recommends that Trimark Associates, Inc, be selected to install, certify and maintain new RIG equipment at the facilities.
