Award Bid No. SUB -806 for furnishing and delivery of a combined metal -clad switchgear enclosure <br />to Crown Technical Systems of Fontana, California, in the amount of $1,343,878.13; <br />2. Award Bid No. SUB -793 for furnishing and delivery of protective relay panels to Keystone <br />Manufacturing Co. of Des Moines, Iowa, in the amount of $53,576.17; and <br />3. Approve Work Order No. 1810532 in the total amount of $5,463,000. <br />BACKGROUND: <br />Electrical substations are where the distribution and transmission systems meet. Substations house critical <br />equipment and infrastructure such as substation power transformers, switchgear units, power circuit <br />breakers, and protective relaying equipment. All this equipment within the substation boundaries is vital <br />for the reliable, safe, and optimum operation of the electric grid. <br />Substation equipment, structures, and protective schemes must be upgraded periodically to meet <br />increasing electric power demand, maintain safety, and improve system reliability. Several of the <br />substation equipment in the Riverside Public Utilities (RPU) system have exceeded, or are reaching, the <br />end of their design life. Replacement of failed equipment such as a power transformer or switchgear is a <br />very expensive and lengthy endeavor due to their design requirements and the complexity of the <br />manufacturing process. The failure of a single unit can result in a significant impact on the electric system's <br />reliability and the safety of employees and the public. <br />Page 55 <br />
