Award Request for Proposal No. 1788 for a Professional Consultant Services Agreement with Las <br />Colinas Engineering DBA Los Colinas Electrical, of Rialto, California, for furnishing, delivering and <br />installing 144 stationary batteries at the Springs Generation Facility for $122,967.20; and <br />2. Authorize the City Manager, or his designee, to execute the Services Agreement with Las Colinas <br />Engineering. <br />BACKGROUND: <br />The Springs Generation Facility (Springs) is one of three power plants owned by the City of Riverside. The <br />facility began commercial operations in July 2002 and produces 40 megawatts of electricity. Springs is a <br />strategic resource for maintaining electric power grid stability, as well as for restoring power after a Citywide <br />power outage. <br />An Uninterruptible Power Supply (UPS) configuration is part of the plant's design. The UPS consists of <br />144 stationary batteries that serve as a backup power source for critical plant equipment. The secondary <br />power source provides protection against costly gas turbine failures and expedites the plant's ability to <br />respond in the event of an emergency blackout situation. <br />Recent maintenance inspections have determined the need for replacement, as the batteries are not <br />maintaining normal electrical charge and have reached the end of their useful life. Operating Springs with <br />a partially functional UPS is not feasible or recommended as a long-term power management strategy. <br />Staff recommends replacing the original stationary batteries with newer and more reliable units. <br />Page 34 <br />
