Electric Utility Supervisory Control and Data Acquisition (SCADA)
Scoping Study
APPROVED BY:
Brian C. Wright, General Manager
RECOMMENDATION:
Authorize the General Manager to execute a contract with TMG — Consulting Engineers
to perform a Supervisory Control and Data Acquisition (SCADA) Scoping Study for an
amount not to exceed of$23,500, plus a ten percent change order allowance of $2,350,
for a total authorization not to exceed $25,850.
BACKGROUND:
The District relies on electric and water utility SCADA systems for situational
awareness, efficient operation, system performance data and emergency response.
Over the years significant investments have been made by the District to further
develop these assets through the SCADA Reliability Improvement Project (SRIP), the
Water SCADA System Project and associated phases of the existing electric utility
SCADA system improvements which are all included in the Electric and Water capital
plans. The District's water utility SCADA system has been fully integrated into the
operations, maintenance and management of water utility production and distribution
systems. With the relatively recent integration of AMI electric metering systems,
updated automated control equipment and the long term goal of incorporating more
advanced smart grid technologies, Staff have identified the need to bring in outside
expertise to assess the needs of the District, current status of the electric utility SCADA
system and evaluate opportunities to optimize and improve.
ANALYSIS AND BODY:
The skill set required for the SCADA Scoping Study is very specialized, often requiring
third party consulting firms to conduct these studies. District staff have had positive
experience with TMG — Consulting Engineers (TMG) who offer such services. District
Code Section: 3.08.050 — Agreements for Special Services, allows for the direct
procurement of special services under which the SCADA Scoping Study. Staff
requested and received a Proposal (See Attachment 1) from TMG to perform a SCADA

Scoping Study for the Electric Department.
The purpose of this study is to provide the District's electric utility with an understanding
of the limitations and potential of the existing SCADA system and infrastructure and to
identify current capabilities and future possibilities. The proposed scope of work will
include-
1. Interview District electric engineering and operations staff to understand how
SCADA is used today, and what information is desired to be displayed;
2. Interview District IT staff to understand the limitations and capabilities of the
existing system;
3. Request data and information to help quantify the results of the interviews; and
4. Create a final report focusing on the current use and limitations, where and how
the District would like to enhance its SCADA, and what is a general plan to
enable those enhancements.
TMG has extensive experience in studying, designing, and commissioning SCADA
systems for a variety of customers including electric utilities, industrial plants, and
complex monitoring and control systems. Their proposed schedule aligns with staff's
plan to optimize and expand the existing SCADA system during and over the next few
years.
