AGENDA TITLE: Adopt resolution authorizing the City Manager to sign a professional services agreement for
McLane Substation Grounding Analysis and Design with Power Engineers, Inc. (not to exceed
$10,000) (EUD).
MEETING DATE: April 4, 2001
SUBMITTED BY: Electric Utility Director
RECOMMENDED ACTION: That the City Council authorize the City Manager to sign a professional
services agreement for McLane Substation Grounding Analysis and Design
with Power Engineers, Inc. in an amount not to exceed $10,000.
BACKGROUND INFORMATION: A portion of the McLane Substation Site was divided off some years ago for
construction of a well. At that time a cyclone fence was installed to provide
physical separation between the two City facilities. The ground grid was left
in place within the entire site. One function of the ground grid in a substation is to reduce step and touch potentials
(voltages) on the perimeter and within the substation to acceptable levels during fault conditions. Solid state control
facilities, now commonly used at well sites, could be exposed to damaging potentials with the present ground grid
configuration. Therefore, to ensure that a safe environment exists around and adjacent to the substation facility, it is
recommended that an analysis of the grounding system be performed and corrective measures, if warranted, be
designed and subsequently implemented.
