On March 1, 2014, during a powerful Pacific storm, an equiprnent failure occurred at Harvey Lynn Substation which resulted in a fire that damaged a significant portion of the substation. Irhe loss of equipment at Harvey Lynn Substation (including, but riot limited to, Transformer 3 (T-3) and T-3 switchgear) accelerated the need for the procurement of mobile transformer equipment. This mobile equipment can be utilized at any of RPU's substations and will assist in the reliability of Riverside Public Utilities' (RPU) distribution system, Work Order 141984.9 is requested to procure this mobile equipment. The purchase considered in this Board action are covered under Section 602 of Purchasing Resolution No. 22576 which provides a Utilities Exception for specialized equipment that is patcular to the needs of the City's Public Utilities Department and provides for acquisition by Open Market Procurement (non- formal bids) if the Purchasing Services Manager determines that it is in the City's best interest. The Purchasing Services Manager made such a determination in this case. Transformer coolers are used to reduce transformer heating which significantly increases transformer capacity and maximizes the life of transformers operating near rated capacities. With the T-3 switchgear and transformer at the Harvey Lynn Substation no longer working, transformers T-1 and T-2 are carrying additional load. The transformer coolers will be used on TAI and T-2 to reduce the risk of overheating due to increased demand during the hot summer months. Once the Harvey Lynn T-3 is replaced, the cooling units will be utilized as needed throughout the system.
