Public Utility District
CONSENT
To: Board of Directors
From: Joe Horvath
Date: November 20, 2013
Subject: Consideration of the Purchase of an Operating System Upgrade to
the Electric SCADA System
1. WHY THIS MATTER IS BEFORE THE BOARD
Board approval is required for expenditures in excess of $15,000.
PA:1[3 1 Is]:T1
The Electric Department's Supervisory Control and Data Acquisition (SCADA) system
was originally installed in 1996. In 2006, the District replaced the SCADA master
station hardware and software due to age and obsolescence of the original
components. These systems are now approaching 8 years in age, the typical life
expectancy of most SCADA systems.
In 2012, the Board approved the purchase of a virtualized server environment for the
District's computer systems (Customer Information, Billing, GIS, Water SCADA,
others). This system is now operating the District's servers in a high availability,
redundant environment. Additional advantages the virtualized server environment
include: improved hardware/software fail over capabilities, reduced administration and
management costs, and a reduction in power costs.
3. NEW INFORMATION
The proposed Electric SCADA server upgrade from a proprietary software operating
system to a Windows operating system allows their installation in the District's virtual
server environment with all of the associated benefits. The proposed upgrade and
associated services will result in the optimization of Electric SCADA operations, a
significant improvement in SCADA system reliability, and reduced maintenance costs
to the District.
The District's SCADA system vendor, Survalent, has assembled a quote to accomplish
the proposed upgrade and associated conversion services. The total cost to perform
this work is $84,316. This price also includes one year of maintenance services at a
cost of about $12,000, an amount which the District currently pays every year in
December.
Due to the highly specialized software and services required for the Electric SCADA
system, staff recommends that competitive bidding be dispensed with in accordance
with District Resolution No. 9606 and the need for the replacement software to
interact, and be compatible, with existing hardware and software.
4. FISCAL IMPACT
Sufficient funds exist in the FY13 Electric Capital Budget for the proposed operating
system upgrade and conversion services for the Electric SCADA system.
There is also a 10% contingency allowance for any potential change orders.
5. RECOMMENDATION
Approve the purchase of an operating system upgrade and conversion services from
Survalent for the Electric SCADA System for a base amount of $84,316, plus a 10%
contingency, for an amount not to exceed $92,748.
