Item No: 7D Meeting Date: February 28, 2011 Type of Business: Council Business Administrator Review: ____ City of Mounds View Staff Report To: Honorable Mayor and City Council From: Don Peterson, Public Works Supervisor Item Title/Subject: Resolution 7747, Approving the Purchase of a Used 80-kW Onan Emergency Generator for City Hall Background: The City Hall Building is designated as the EOC (Emergency Operating Center) in the Emergency Operation Plan for the City of Mounds View. As staff continues preparing the building for this designation, one of the items looked at was an alternate power supply for keeping the building open in critical or emergency operations during power outages. Last year the City Hall building had electrical work done by installing a transfer switch for hooking up a portable generator as an alternate power supply for this purpose. The long-term goal is to purchase a stationary emergency generator to be dedicated for City Hall, which is reflected in the Capital Improvement Program and 2011 adopted budget. Public Works staff recently found a used 2001 80-kW Onan emergency generator at SASP, the Government Surplus Facility in Arden Hills. The Onan brand was manufactured at the Cummings Power facility on County Road H2 in nearby Fridley. This unit was only owned and used by the US Air Force at an air force base in Mountain Home, Idaho. The hours on the unit are low, and according to Cummings NPower, these hours correspond to monthly exercise test hours. Staff made the City Council aware of this find at a January meeting and Council recommended pursuing further evaluation. Public Works Staff evaluated the compatibility of the generator being used at City Hall. After consulting with Bonestroo, it was determined that the size (80-kW), voltage, and connections were compatible for use at City Hall. Further direction was given to have the generator run and tested to see what condition it was in. SASP allowed the City to bring the unit to the Public Works Facility for further evaluation, and Cummins NPower was went through the unit and tested by placing a electric load on the power plant while the generator is running. After thorough examination, replacement of a missing part, and successfully passing the tests, Cummins NPower determined that the unit was in very good shape, ran great, and recommended that the City purchase the unit. Discussion: The generator is priced by SASP at $5,000 - this is a great price since the engine is estimated to be worth this amount alone (the other major components on the unit are power generation and controllers). There are some additional items that need to be added to the unit. These items include a new protective weather enclosure, silencer kit with tubes and rain cap, a new 140-gallon double wall subbase tank, assembly of all the components at a cost of $9,750 plus tax. These items would be purchased from Magnus Incorporated out of Milaca, MN. The total cost for the unit, enclosure, fuel tank, and assembly is $14,750 plus tax. Parts and evaluation/commissioning costs to date are $1,493.20 for an estimated “fully-functional” generator unit cost of $16,243.20 plus tax. This compares favorably to the $65,000 budgeted for in the 2011 budget.
