DATE: June 17, 2025
SUBJECT
Consider adoption of an ordinance of the City of Denton, a Texas home-rule municipal corporation,
authorizing the City Manager to execute a contract with Schweitzer Engineering Laboratories, Inc., for the
purchase of Protective Relay Panels for multiple substations for Denton Municipal Electric; providing for
the expenditure of funds therefor; and providing an effective date (RFP 8712 – awarded to Schweitzer
Engineering Laboratories, Inc., in the not-to-exceed amount of $551,600.00). The Public Utilities Board
recommends approval (6 - 0).
STRATEGIC ALIGNMENT
This action supports Key Focus Area: Enhance Infrastructure and Mobility.
INFORMATION/BACKGROUND
Denton Municipal Electric (DME) has several projects in its five (5) year Capital Improvement Plan that
require the purchase of protective relay panels that house microprocessor-based protective relays, control
switches, test switches, and other devices necessary to operate and protect transmission lines, distribution
lines, and substation equipment. The projects are as follows:
• Underwood Substation – New substation in southwest Denton
• Denton West Interchange Brazos Tie-in – Addition to provide facilities to connect two new
transmission lines.
• RD Wells Substation – New panel for transmission line to the new Underwood Substation.
• Jim Christal Substation – Two human monitor interface (HMI) panels for communication in the
switchgear buildings
• Miscellaneous Plates – Steel plates required for existing panel adaptations.
Protective relays are the “brains” of the protection systems that continuously monitor currents, voltages,
and other inputs, and initiate actions, including opening circuit breakers when abnormal conditions are
sensed, and perform other protective actions. Relays also provide metering functions, remote terminal unit
functions (RTU), and control output functions. Relay panels are fabricated from steel to provide a sturdy
framework for mounting protective relays and other equipment required for protection and control inside
the substation. Relay panel construction includes installation of wiring, mounting of all hardware, testing,
and delivery to Denton Municipal Electric.

The cost for this contract is only for the manufacture and delivery of the relay panels. DME has a separate
contract with Schweitzer Engineering Laboratories, Inc. (SEL) for the purchase of the protective relays that
are housed in the relay panels. The SEL protective relays are shipped directly from SEL to the panel
manufacturer for installation into the relay panels.
The contract estimate is based on the quantities of panels needed for the CIP projects listed below. A 10%
contingency was added for any unforeseen design changes.
