AGENDA TITLE: Approve Requestfor Proposal and Authorize Advertisement for the Inspection,
Adjustments and Maintenance Tests of Two Power Transformers at Henning
Substation (EUD)
MEETING DATE: June 3,2009
PREPARED BY: Electric Utility Director
RECOMMENDED ACTION: Approve a Requestfor Proposal and Authorize Advertisement for
services to perform inspection, adjustments, and maintenance tests
of two power transformers and associated load tap changers at
Henning Substation.
BACKGROUND INFORMATION: There are two 31.25 MVA power transformers and associated load
tap changers (LTC's) installed at Henning Substation. One
transformer has been in operation since 1976 and the other since
1984. The last maintenance tests were conducted on these
transformers in 2003.
Power transformers of this rating are typically maintained on a regular basis (five years or less). Since it
has been approximately six years that comprehensive maintenance tests were conducted on these
transformers, it is prudent to perform such work at this time. Staff proposes to contract this work because
the job requires special tools, equipment and parts.
In order to maintain safe and reliable operation of the power transformers in Henning Substation, staff
recommends the approval of this request. Maintenance services shall be performed between October -
November 2009.
FISCAL IMPACT: Estimated maintenance and repair cost is $40,000.
FUNDING AVAILABLE: Account No. 160653.7323— Substation Maintenance
