Battery Bank at Industrial Substation
MEETING DATE: August 20, 2014
PREPARED BY: Electric Utility Director
RECOMMENDED ACTION: Approve specifications and authorize advertisement for bids for
replacement battery bank at Industrial Substation.
BACKGROUND INFORMATION: The Electric Utility (EU) maintains four distribution substations that
transform sub -transmission voltage from 60kV to 12kV, for the
purpose of providing service to its 26,000 customers. Industrial
Substation was commissioned in January 1991 and utilizes a 125 volt direct current battery bank for the
primary and back-up controls for operating the substation, which includes all supervisory functions. The
original battery bank is 23 years old and has outlived its life expectancy of 15 years and is now showing
signs of decay that jeopardize the reliability of the substation.
The proposed specifications indicate two distinct bids to be provided; the first for materials only; the
second for contract labor and materials to replace the battery bank. The specifications are on file at the
Electric Utility, located at 1331 South Ham Lane. The planned bid opening date is Tuesday, September
2, 2014.
FISCAL IMPACT: The total cost of the battery bank is estimated to not exceed $35,000.
FUNDING AVAILABLE: Included in FY2014/2015 Account No. 161082.
