HomeMy WebLinkAboutE-2.1. Approve Purchase of Circuit Breakers and Issue PO to Western Utility SolutionsCONSENT CALENDAR E-2
TO: HONORABLE CHAIRPERSON AND MEMBERS OF THE AZUSA UTILITY
BOARD
FROM: TIKAN SINGH, GENERAL MANAGER
DATE: JULY 25, 2022
SUBJECT: APPROVE THE PURCHASE OF CIRCUIT BREAKERS AT KIRKWALL
SUBSTATION AND ISSUE PURCHASE ORDER TO WESTERN UTILITY
SOLUTIONS, INC. IN THE AMOUNT NOT TO EXCEED $61,022
BACKGROUND:
The Kirkwall Substation was built and commissioned in 2004 to serve electric power to
approximately one third of customers in the City of Azusa. At the Kirkwall Substation, there are
six feeder circuit breakers and two main bus circuit breakers. These circuit breakers are eighteen
years old, and their replacements are not readily available. To maintain system reliability, and
avoid extended power outages in the event that one of the circuit breakers should fail, Staff
recommends purchasing one spare feeder circuit breaker and one spare main bus circuit breaker.
Staff solicited and received sole source price quote for one feeder circuit breaker and one main bus
circuit breaker from Western Utility Solutions, Inc. The proposed actions waive the competitive
purchase requirements pursuant to the Azusa Municipal Code Section 2-517(a)(34), Article VII,
and authorizes a Purchase Order in an amount not-to-exceed $61,022 for a feeder circuit breaker,
and a main bus circuit breaker.
RECOMMENDATION:
Staff recommends the Utility Board take the following actions:
1) Waive the competitive purchase requirements pursuant to Section 2-517(a)(34), Article
VII, Chapter 2 of the Azusa Municipal Code (Substation Supervisory Equipment); and
2) Approve the purchase of one (1) new feeder circuit breaker rated at 25KA-1200A, and
one (1) main bus circuit breaker rated at 25KA-2000A; and
3) Authorize the issuance of a Purchase Order to Western Utility Solutions, Inc. in the
amount not to exceed $61,022.

ANALYSIS:
Circuits breakers in the substation are equipment that will trip/interrupt the flow of electricity when
short circuits or abnormalities are detected on that feeder to protect lives and equipment. Thus,
circuit breakers play a very important role in the protective scheme of an electric system. At the
Kirkwall substation, there are six feeder circuit breakers and two main bus circuit breakers.
Although they are routinely maintained and in good operational condition, these circuit breakers
are 18 years old. They have passed half of their life expectancies. If any of these circuit breakers
become defective, there will be no protection on that feeder. The unique design at the Kirkwall
Substation allows each of these circuit breakers to be racked out for maintenance or for
replacement. The spare circuit breaker can be racked in the place of the defective one in the matter
of minutes, analogous to a spare tire of a vehicle, which would avoid extended down time of
repairing the defective unit. Therefore, Staff wishes to purchase the spare circuits breakers now
versus waiting for them to fail at an unexpected time.
Pursuant to Municipal Code Section 2-517, circuit breakers are exempt from competitive bidding
processes in purchasing. Staff has solicited and received a sole source price proposal for the circuit
breakers from Western Utility Solutions, Inc. in the amount of $61,022. Staff has reviewed and
determined that the proposal submitted by Western Utility Solutions Inc. has met all specifications
and requirements for the circuit breakers at the Kirkwall Substation

Also, it is important to know if the compartment where this breaker is going to be installed have a
MOC/Auxiliary Switch, and the date when this (the compartment) was manufactured. Depending on the
