This generator is probably thirty years old and is a 150 KW. To make the Police Department a full Emergency Operations Center requires that full amount (150 KW) and more; at this point the generator has not been tested as to its true output and, thereby, its rating. The transfer switches are more sophisticated in their diagnostics than the generator is in its ability to respond. The City, with the purchase and the demilitarizing/rebuilding of the unit, has spent a total of $11,084 on the generator. There are several vendors who will submit bids for buying it. On an emergency basis, I have authorized the purchase of a new Cummins/Onan 350 KW, 300 gallon base fuel tank for $41,600.00 and a new 800 Amp transfer switch for the Police Department at a cost of $15,961.40. The availability of such a switch and the fact that it has to be flown to two locations - one to enclose it for outside use and back for testing before it gets to Ocoee - drives the cost up some $6,000.00 (none of this travel is eligible for frequent flyer miles). Computer Power Systems, Inc. provided the attached cost comparisons, the steps to complete, and the downtime for both buildings. The City has received response from Amber (Huber Construction's sub-contractor) as to their willingness to cooperate since the City has no as-builts, their time and materials to complete the work as outlined, and their schedule for beginning these tasks. The generator and transfer switch will be on site Monday afternoon or at the latest Tuesday morning. Florida Power Corporation will cut power as necessary. Monies to be provided through the $200,000 allocated at mid-year to the project. 1 Staff Report/Beamer/Generator July 29, 1994 Staff Recommendation: The Honorable Mayor and Board of City Commissioners approve the emergency purchase of the generator, transfer switch, Amber's time and materials, Huber's supervision and Computer Power System's time and material to complete the work necessary for relocating the Police Department to its new building and confirm these emergency purchases. 2 COMPUTER POWER SYSTEMS, INC. 251 E.

Lakeshore Drive Ocoee, FL 34761 Subject : Generator Pricing Dear Ms. Beamer: After careful review, the most cost effective generator size for your new complex has been determined to be 350 KW. This capacity will allow for total back-up of the Police Station and the existing circuits now on generator power in City Hall , with approximately 20% reserve capacity. This size system will fit on your existing generator pad with ample space for the required switch gear and conduit rework. As you are aware, space in this area is a factor and plays a role in sizing consideration. Also, 1 week delivery is mandatory. The following prices have been quoted for this project : - Ringhaver : Cat 320 KW, 270 gallon base fuel tank, used system with approximately 1200 hours $41 ,900 .00 - Transfer switch (NEMA 3R) not available until september - Core Power: Cat 355 KW, 300 gallon base fuel tank, used system with approximately 2000 hours $45,000 .00 - Transfer switch, 800 Amp, NEMA 3R, new $15 .961 .40 ( Includes overnight , 2 states, and next day delivery) - Cummins Southeastern: Cummins/Onan 350 KW, 300 gallon base fuel tank, new system $41 ,600 .00 - Transfer switch (NEMA 3R) not available until late August It is our recommendation that the Cummins/Onan new unit be purchased along with the transfer switch from Core Power .
