YCITY OF LODI COUNCIL COMMUNICATION
AGENDA TITLE: Adopt a Resolution Authorizing the Non-competitive Purchase of a Supervisory, Control and
Data Acquisition (SCADA) System and Software Upgrade from Siemens/TeleGyr Systems,
Inc. ($165,000.00) (EUD)
MEETING DATE: May 2, 2001
PREPARED BY: Electric Utility Director
RECOMMENDED ACTION: That City Council adopt a resolution authorizing the non-competitive
purchase of a replacement/upgrade of the master station and software for the
City's Supervisory, Control and Data Acquisition (SCADA) from
Siemens/TeleGyr Systems, Inc.
BACKGROUND INFORMATION: The present SCADA system was purchased in 1989 from Landis & Gyr, now
Siemens/TeleGyr Systems, Inc., to provide for the automatic control and
monitoring of the City of Lodi's Electric and Water Systems. However, since
1989, new substations, water wells, electric circuits, storm pumps and sewage lift stations have been installed to
provide for the city's growth. As a result of additional equipment being added, the present SCADA system has
reached its operational capacity due to lack of memory in the master station. Memory expansions are not available for
this system. Other critical hardware components are no longer available. In addition, the new technology and
features that would enhance the operation of the City's Water and Electric systems, i.e. improved efficiency and
response time cannot be adapted to our present SCADA system.
After careful research, the department has determined that an upgrade from Siemens[TeleGyr Systems, Inc. to the
existing master station is in the best interest of the City of Lodi for the following reasons:
It allows the use of three master station protocols simultaneously. One, of which, is currently being used by the
present Scada master station and Remote Terminal Units (RTU's). This eliminates the mandatory requirement for
either a protocol change or an emulation of a proprietary protocol, as would be the case if any of the other vendors
were selected. It eliminates the need to spend any labor dollars changing the protocol at the substations, water wells,
storm pumps and sewage lift stations. It allows for a seamless switchover from the old SCADA system to the new
SCADA system.
Both systems are allowed to run in parallel to insure that the new SCADA system works to our satisfaction. This
provides the City of Lodi with the option of waiting until the new SCADA system is fully operational before the old
system is shut down.
The Siemens/TeleGyr system upgrade requires less hardware, thereby, reducing the opportunity for system failures.
The Siemens/TeleGyr system upgrade provides for faster takeover from failure of the on line unit due to the speed in
which each server is updated. Less training is needed due to familiarity and present use of the Siemens/TeleGyr
equipment.
This resolution would authorize the purchase of the SCADA system from Siemens/TeleGyr for $165,000.00 under City
Code Section 3.20.070 ("Bidding shall be dispensed with when the City Council determines that the purchase or

A RESOLUTION OF THE LODI CITY COUNCIL AUTHORIZING THE
NON-COMPETITIVE PURCHASE OF A SUPERVISORY, CONTROL
AND DATA ACQUISITION (SCADA) SYSTEM AND SOFTWARE
UPGRADE FROM SIEMENS/TELEGRY SYSTEMS, INC.
WHEREAS, Lodi Municipal Code, §3.20.070, authorizes dispensing with bids for
purchases of supplies, services or equipment when it is in the best interest of the City to
do so; and
WHEREAS, the present SCADA system was purchased in 1989 from Landis &
Gyr, now Siemens/TeleGyr Systems, Inc., to provide for the automatic control and
monitoring of the City of Lodi's Electric and Water Systems; and
WHEREAS, since 1989, new substations, water wells, electric circuits, storm
pumps, and sewage lift stations have been installed to provide for the City's growth. As
a result of additional equipment being added, the present SCADA system has reached
its operational capacity due to lack of memory in the master station; and
WHEREAS, memory expansions are not available for this system. Other critical
hardware components are no longer available. In addition, the new technology and
features that would enhance the operation of the City's Water and Electric Systems, i.e.
improved efficiency and response time, cannot be adapted to our present SCADA
system; and
WHEREAS, after careful research, the department has determined that an
upgrade from Siemens/TeleGyr Systems, Inc. to the existing master station is in the best
interest of the City of Lodi for the following reasons:
1) It allows the use of three master station protocols simultaneously, one of
which is currently being used by the present SCADA master station and

Siemens/TeleGyr Systems, Inc., in the amount of $165,000.00,
NOW, THEREFORE, BE IT RESOLVED that the City Council of the City of Lodi
