RESOLUTION APPROVING RAPID NEEDS REPORT
FOR UNIT 8 TURBINE REPAIR AT THE POWER PLANT
FOR THE CITY OF AMES,IOWA
WHEREAS, on May 11, 2023, Unit 8 turbine experienced a high vibration event causing
the unit to automatically shutdown to prevent the possibility of further damage. After an in-depth
internal investigation, staff determined it was necessary to hire a turbine specialist company to
inspect the turbine through a rapid needs purchase,which occurs when materials or services could
not have been predicted and must be procured in less than the normal time in order to continue a
service to the public; and,
WHEREAS, the City Manager's Office authorized a rapid needs purchase order in the
amount of $42,500 to inspect the unit for Blade Runner Turbomachinery Services LLC, of
Navasota, Texas, which last performed the turbine/generator overhaul on Unit 8; and,
WHEREAS, there were three change orders to the purchase order. The City Manager's
Office approved Change Order No. 1 in the amount of$34,600 to remove the Unit 8 turbine case
and rotor, transport the rotor, and perform inspection in a turbine shop. After considering three
alternatives to accomplish the blade manufacturing and assembly, staff approved Change Order
No. 2 in the amount of $299,800 to install 45 replacement blades, repair blades in two other
sections, replace the shaft seals, and perform final balance testing. Change Order No. 3 in the
amount of$35,000 was issued to replace the extra blades; and,
WHEREAS, the total of the repair costs for Unit 8 turbine was $411,900. The necessary
repairs are now complete, and Unit 8 turbine has returned to service. The repair costs were paid
from the Electric Production Operations and Maintenance budget and advanced funds from the
Capital Improvement Plan for Unit 8 minor and major turbine overhauls.
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Ames, Iowa,
that the report of the rapid needs purchase for repairs to Unit 8 turbine is hereby approved.
