CITY OF COLTON <br />AGENDA REPORT <br />FOR COUNCIL MEETING OF JANUARY 20, 2004 <br />TO: HONORABLE MAYOR AND CITY COUNCIL <br />FROM: Tom Clarke, Electric Utility Director_v(/� <br />SUBJECT: Award of Bid for Various Transformers to Pauwels <br />Transformers in the Amount of $84,125.81 <br />DATE: December 29, 2003 <br />Item #4 <br />BACKGROUND: <br />The City purchases transformers into Electric Stores inventory when the need arises to upgrade, <br />replace, or install a new transformer for an Electric customer. The City also orders back-up <br />transformers to be used to replace a transformer that goes bad in the system. Back-up <br />transformers are necessary, due to the long delivery time. <br />At this time, the Electric Utility has a requirement for various sizes of padmount transformers to be <br />used for back-up. <br />DISCUSSION/ANALYSIS: <br />On November 24, 2003, the Utilities Department posted a Notice Inviting Bids for these <br />transformers. Bid packages were mailed to five suppliers of distribution transformers. A bid <br />opening was held at 2:00 P.M. on December 16, 2003, at the Electric Department Administrative <br />offices. Four bids were received and evaluated. <br />A Bid Analysis is attached showing the price and delivery quoted by each vendor. The <br />recommended vendor's price is underlined for each size transformer. The total of bid award is <br />listed at the bottom for the recommended vendor. <br />Also attached is a Transformer Load Loss Evaluation. This evaluation shows the life cycle cost of <br />the transformer over its useful lifetime, using a combination of loss calculations supplied by the <br />transformer manufacturer and the unit price quoted by the vendor. To evaluate the lowest cost bid, <br />the life cycle costs demonstrate the cost of the transformer over its "in-service" life, taking into <br />consideration the degradation over time. The transformer that loses the least over the useful life <br />results in the lowest cost of the equipment. It is a function of which manufacturer has the least loss. <br />The lowest evaluated cost for each transformer is underlined and recommendations are made from <br />the result of this evaluation. <br />FINANCIAL IMPACT: <br />These transformers are purchased into Electric Stores inventory account number 520-1500-154. <br />The transformers are charged to the appropriate budgeted account, as they are needed. <br />ENVIRONMENTAL IMPACT: <br />None. <br />
