DATE: July 19, 2022
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 Power Monitors, Inc., for the purchase of pole
mounted, ethernet-based three-phase PMI End-of-Line voltage and current recording, monitoring, metering,
software, integration, accessories, and devices for Denton Municipal Electric, which is the sole provider of
these items, in accordance with Texas Local Government Code 252.022, which provides that procurement
of commodities and services that are available from one source are exempt from competitive bidding, and
if over $50,000, shall be awarded by the governing body; providing for the expenditure of funds therefor;
and providing an effective date (File 8008 – awarded to Power Monitors, Inc., in the three (3) year not-to-
exceed amount of $204,643.74). The Public Utilities Board recommends approval (6 - 0).
INFORMATION/BACKGROUND
In 2017, Denton Municipal Electric (DME)’s Electric Engineering researched methodologies to reduce
power consumption during the Utility’s four-coincident-peak (4CP) months. 4CP is the average of DME’s
peaks during the highest ERCOT grid peak hours for each of the four summer months. Distribution grid
management, through peak shaving, during the 4CP months will lead to a reduced annual energy cost and
more importantly, lower Transmission Cost of Service (TCOS). DME engineering performed industry-wide
research and evaluated several methods for peak shaving. Conservation Voltage Reduction (CVR) was seen
as very attractive due to its ease of implementation and low upfront cost. CVR is the practice of intentionally
lowering the voltage on primary distribution circuits while maintaining voltage within the acceptable
voltage range defined by the American National Standards Institute (ANSI) standards.
As a proof-of-concept, DME Electric Engineering selected six feeders with varying load profiles and ran a
pilot program in 2019 using PMI’s voltage monitoring and recording devices. Successful execution of CVR
protocols requires the Utility to know, in real-time, that the delivery voltage at the end of a circuit is within
standards. To provide this information, DME chose PMI’s Boomerang product for reporting real-time, end
of the circuit, and voltage. Boomerangs are microprocessor-based sensors that are managed through
Software as a Service (SaaS) and provide accurate voltage telemetry and triggering in real-time via the
Utility’s current Advanced Metering Infrastructure ethernet/Trilliant radio system. The proof-of-concept
was successful and DME’s Systems Operators run CVR every 4CP season.
To expand DME’s CVR capability and increase TCOS and energy savings for its customers, DME is
proposing the purchase of (100) additional PMI Boomerang monitors.
