RESOLUTION AWARDING CONTRACT FOR
ENGINEERING SERVICES AT THE POWER PLANT FOR
GAS TURBINE 1 MOTOR CONTROL CENTER RETROFIT
FOR THE CITY OF AMES,IOWA
WHEREAS, the City operates two combustion turbines as secondary sources of power
generation. One of the combustion turbines is Gas Turbine-1 (GT 1). GT 1 is a dual-fuel capable
Pratt & Whitney simple-cycle aeroderivative gas turbine which drives a Worthington expander
coupled to an Electric Machinery air-cooled generator. GT 1 was placed into service in 1972 and
has a rated capacity of 18,000 kilowatts (18 MW); and,
WHEREAS, the switches, valves, and other electrical components that operate GT 1 are
controlled from a centralized Motor Control Center(MCC). The MCC for GT1 was last upgraded
in 2009. The communications protocol selected in the upgrade is proprietary to the manufacturer
and is now obsolete. Electric Services has had several issues with communications to the MCC,
which has affected unit reliability; and,
WHEREAS,the City is currently performing a combustion control system upgrade for both
of the combustion turbines, using AP4 as the engineering firm. AP4 does not have the capability
to provide MCC engineering. It has become apparent that retrofitting the GT1 MCC controls and
communication at the same time as the combustion control system upgrade project is required to
assure success of both projects and improve reliability; and,
WHEREAS, on June 8, 2023, a Request for Proposals (RFP)was posted to AmesBids. On
July 6, 2023, two proposals were received. The proposal from Zachry Engineering Corporation,
of Omaha, Nebraska, demonstrated an acceptable project understanding and presented qualified
professionals for the project at an acceptable price. The FY 2023/24 budget includes $600,000 for
the completion of Combustion Turbine#1 Controls Upgrades.
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Ames, Iowa,
that award of contract to Zachry Engineering Corporation, Omaha, Nebraska, for Engineering
services for Gas Turbine 1 Motor Control Center Retrofit in an amount not to exceed $96,000 is
hereby approved.
