AGENDA TITLE: Purchase of Padmount Transformers ($42,039.74)
MEETING DATE: December 18, 1996
PREPARED BY: Electric Utility Director
RECOMMENDED ACTION: That the City Council adopt the attached resolution awarding the
bid for the purchase of four padmount transformers to the bidders
whose proposals and equipment met City of Lodi specifications,
and whose transformers are expected to yield the lowest overall
life -cycle costs, G E Supply Company of Sacramento in the 500KVA class (three units totaling
$29,131.29), and Western States Electric of Portland, Oregon, in the 1000KVA class (one unit at
$12,908.45).
BACKGROUND INFORMATION: On November 6, 1996, the City Council approved specifications
and authorized advertisement for bids for four padmount
transformers.
On December 3, 1996, bids were opened and total life -cycle costs were evaluated. Life -cycle costs are
the combined total of purchase price plus cost of operation based on estimated power loss during the
projected life of the transformer. Proposals are also evaluated on the basis of compliance with
equipment and bid specifications. Failure to comply with both may lead to disqualification of the bid. A
summary of the bid evaluation is attached.
These transformers will be used to serve new industrial load, upgrade existing commercial installations,
and to replenish the Department's inventory of transformers.
