� EN HILLS MEMORANDUM DATE: July 9, 2012 TO: Honorable Mayor and City Councilmembers Patrick Klaers, City Administrator FROM: Terry Maurer, Public Works Director � �� SUBJECT: City Hall Generator Conversion Back�round Public Works has three generators for temporary service to lift stations in the case of a power outage. The newest of these is the used generator purchased in 2010 and permanently placed at lift station #8. This generator is on wheels but will generally be used for LS #8. That leaves two portable generators for the remaining 13 lift stations. One of these is a 1999 Caterpillar and the other is an early 70's Kato. The Kato generator recently broke down and was taken to Clunmings Power to diagnose the problem. They did diagnose the problem and estimated the repair at $8,000; however, they cautioned us about putting that much money into such an old generator since parts for the motor are no longer available. With this information, staff started to look into other options. For budgetary purposes we asked 'Liegler Caterpillar the cost of an adequately sized new and used generator. A new one would be in the $62,000 range and a used one (2006 from their rental fleet with about 4000 hours) would be in the $38,000 range. This is very similar to the used generator purchased for LS #8. 1 here is another option; the City has a 2003 Olympian (Caterpillar) generator for running City Hall in an emergency. That generator has very few hours of use (less than 300 hrs). For about $9,000 Zeigler can add a two position voltage change switch with a 200 amp and 480/240 volt breakers so the generator could be used at lift stations or to run City Hall. This may not be a long term solution but would at least "buy" some time before making a much larger investment for a used generator to run the lift stations.
