A purchase order in the amount of $124,293.00 is requested for Siemens Energy to complete repairs of the main oil pump on Blue Valley Unit #1 and to complete the upgrade of the governor valves on Blue Valley Units #1 and #2.
The main oil pump on Unit #1 is a critical component of the turbine generator. Normal operations cause wear on the main oil pump with the result of not producing adequate oil pressure, which is critical for proper operation. Foregoing repairs to the main oil pump could damage the unit, which would then be removed from the Integrated Market unit availability list for an extended period during repairs and could potentially result in higher costs for Power and Light customers.
The governor valve controls the over-speed of a steam turbine generator. The current governor valves on Units #1 and #2 require an upgrade critical to maintain reliable operation of the units. The upgraded governor valve will increase operational control of the unit, which in turn increases efficiency and reliability of the steam units.
Siemens Energy is the original equipment manufacturer (OEM) and single source for this service. The work will be completed by OEM factory trained technicians and craftsmen to ensure that repairs will be completed as per design and workmanship of the highest quality.
Approval authorizes the Purchasing Manager to issue change orders up to a total of ten (10) percent of the original amount, providing that appropriations are available.
