AGENDA TITLE: Approve the plans, drawings and specifications and authorize advertisement for
bids for the reconstruction of Killelea Substation, the addition of 6OkV power circuit
breakers (PCB) at Industrial Substation and procurement of Two (2) 60f12kV
Power Transformers (EUD)
MEETING DATE: August 3, 2005
PREPARED BY: Electric Utility Director
RECOMMENDED ACTION: Approve the plans, drawings and specifications and authorize
advertisement for bids for the reconstruction of Killelea Substation,
the addition of 60W PCB at Industrial Substation and procurement
of two (2) Power Transformers.
BACKGROUND INFORMATION: The Killelea Substation was constructed in 1965. The 12kV section
is enclosed, metal -clad switchgear. The manufacturer of this
equipment is no longer in business making parts extremely difficult
to locate. The design of the switchgear is such that a failure of one portion of the insulated bus would
likely escalate throughout the entire switchgear making a failure catastrophic resulting in a total loss of
the station. The 6OkV structure was the interconnection facility as well as the main 60kV distribution
structure prior to the construction of industrial Substation. A large portion of this structure is no longer
needed and adds unnecessary exposure to the City's electric system. With the significant industrial
growth on the east side of the City, this station will remain a necessary and vital part of the City's electric
system and requires reconstruction to remain a reliable and dependable substation.
On June 7, 2000, the City Council authorized a study by Power Engineers, Inc. to identify and evaluate
various options for the reconstruction of the Killelea Substation. These options included different
technologies and configurations for the substation. Based on the following criteria such as cost,
operating flexibility, maintenance, reliability, longevity, equipment access with minimum power
interruptions and aesthetics, one option emerged as the preferred solution. This recommended option
requires complete reconstruction of Killelea Substation that entails the following improvements:
1. Two (2), new, 60/12kV with LTC, 35MVA power transformers
2. Conventional -open bus layout, low -profile structure and drive-through access for both 6OkV and
12kV busses
3. Masonry block wall around the entire substation and new control building
4. Acquisition of adjacent property
5. Addition of two (2) BOW power circuit breakers and appurtenances at Industrial Substation
On August 6, 2003, the City Council authorized the engineering services of Power Engineers, Inc. to
prepare construction drawings, contract plans and specifications for the procurement of two (2) power
transformers, the reconstruction of the whole Killelea Substation and the addition of two (2) BOW PCB at

Industrial Substation in accordance with the recommended option above. Said documents were
completed on January 19, 2005. Project bid specifications were consolidated and made ready for
advertisement and bid solicitation. Copies of detailed plans and drawings for this project are available in
the Electric Utility Department and will be provided upon request.
For purposes of improving reliability of power distribution system operation, we recommend City Council
approval of the plans, drawings and specifications as well as City Council authorization to advertise for
bids for the reconstruction of Killelea Substation, 60kV PCB addition at Industrial Substation and
procurement of two (2) power transformers.
Additionally, the reconstruction and corresponding expansion of Killelea Substation requires the
acquisition of the adjacent residential property owned by Pete and Helen Perlegos at 541 E. Locust
Street. A resolution of the City Council finding that public interest and necessity requiring the acquisition
of this property was approved on August 21, 2002 as per Resolution No. 2002-178. Preliminary title
report was submitted to the Office of the City Attorney. Acquisition of the property will be executed by The
City Attorney.
