CITY of DENTON / 215 E McKinney / Denton Texas 76201
MEMORANDUM
TO Robert Nelson, Executive Director of Utilities
John Marshall, Purchasing Agent
FROM Ray D Wells, Superintendent,
Metering/Substations/Communications
DATE August 9, 1989
SUBJECT P O Number 91695 - Explanation and Support
Documentation
The purchase of radio equipment listed on the above referenced
purchase request is necessary to allow the City of Denton
Electric Utility Department to operate S C A D A (Supervisory
Control and Data Acquisition) equipment between the Lake
Lewisville Hydro Project, Brazos Electric Co-op, Inc , Lewisville
Substation, and Denton Spencer Plant The leasing of telephone
lines would be extremely costly between these points, and the
baud rate the system could operate at would be too slow The
purchase of this equipment will also allow us to operate our
existing R T U (Remote Terminal Unit) located at Denton West
Interchange by radio, and enable us to discontinue the lease line
with a T E resulting in a $264 70 per month reduction in
operating expense We would also be able to incorporate the Lake
Ray Roberts Hydro Project and proposed Water Plant facilities
The reason for listing Motorola Communications as vendor is that
this equipment is completely compatible with our existing A C S
S C A D A equipment and the Brazos' microwave link to Waco
dispatch center Purchase of radio equipment of another type
would result in additional costs for interface equipment and
engiXQering
