CITY OF COLTON AGENDA REPORT FOR COUNCIL MEETING OF July 1, 2003 TO: Honorable Mayor and City Council FROM: Thomas K. Clarke, Electric Utility Director Item #10 SUBJECT: Award of Sole Source Contract to Schweitzer Engineering Laboratories, Inc., C/O Matzinger-Keegan, Inc., for the purchase of Schweitzer Protection Relays for the Electric Utility, in the Amount of $57,935.04 DATE: June 23, 2003 BACKGROUND. The Century Substation was built in 1986 and is located at 661 S. Cooley. The primary feed to the substation is 66,000 volts (66 kv). The secondary side of the transformer is 12,000 volts (12 kv). On the 12 kv side we have 6 distribution circuits which feed power to the Cooley Ranch area. Protection relays operate when a fault occurs on our electric lines and trip a 66 kv or a 12 kv circuit breaker. The type of protection relays used on the 66 kv lines are ASEA, that were made in Sweden. These relays are first generation electronic relays for which technical support is no longer provided. The type of protection relay on the 12 kv lines are Basler. These relays normally should provide useful information to substation personnel when power outages occur. However these relays are incorrectly indicating fault conditions that can prolong power outages. Both of these types of relays have failed during testing which puts our electrical system at risk during fault conditions. DISCUSSION/ANALYSIS: In August of 2002, Council approved the sole source contract to Schweitzer Engineering Laboratories, Inc. (SEL) for the purchase of protection relays at the Hub Substation. In 1995 the Drews Substation was built to City specifications which included SEL protection relays. The City of Colton has set the standard when replacements are required. The justification for sole source is as follows: The Colton Municipal Code Title 3 Chapter 3.08.060 states, in part, as follows: "...bidding may be dispensed with ... when the commodity is a sole source item which can be obtained from only one vendor. Sole source items shall include purchases of items where there are restriction in specification due to the need for standardization." FINANCIAL IMPACT: The purchase of these relays was budgeted in FY 02/03 in the Electric Utility Capital Miscellaneous Equipment Account Number 520-8000-8003-4930-0101-000. ENVIROMENTAL IMPACT: None
