RECOMMENDATION
The Utility Operations Department recommends the City Council award the bid for Variable Frequency
Drives for the Water Purification Plant to Control Concepts Inc., of Houston, TX, in the total amount of
$58,000.
BACKGROUND
The centrifuges at the Water Purification Plant utilize 300HP main drive electric motors, and consume a
total of about 400HP. These units draw enormous electrical demands during startup (about double
normal donsumption) and our Entergy bill is a function of peak demands at the plant. The use of
Variable Frequency Drives will allow these motors to consume much less electricity during startup and
save on electricity. We should also be able to operate the centrifuges while operating on our
generator(s) due to the lower loads. Eleven (11) bid packets were sent out and five (5) bids were
received on December 12,2007 and advertised on November 18 and.November 25, 2008.
