Title
Mobile Generator Transfer Switch Project
History
The Village recently acquired an 800kW mobile trailer generator to serve as a dispatchable emergency power source for any Village facility lacking its own permanent generator, including the Civic Center, the Franklin Loebe Center (FLC), the SportsPlex, and CPW. The generator is currently stationed at Public Works. Public Works’ existing backup setup, consisting of 150kW and 80kW generators, can power only a portion of the building, leaving phone lines inoperable and large areas of the facility without electricity during an outage.
The Public Works Renovation Project, which includes a dedicated backup generator sized for the entire facility, is likely still one to two (1-2) years from installation. In the interim, staff identified the 800kW mobile generator as an ideal means of bridging that gap. For the generator to supply power to the building immediately in the event of an emergency, however, a transfer switch rated for the new power source is required, as the existing switch at Public Works cannot accommodate it. The new transfer switch will remain with the mobile generator, and can be used during mobile operations at other Village facilities, so its value extends well beyond the interim period at Public Works. Once the facility’s dedicated generator is installed, the mobile unit and its transfer switch will return to their intended role as a dispatchable resource for the Village.
Public Works developed a scope of work, referred to as the Mobile Generator Transfer Switch Project, that addresses backup power connections and a service modification at Public Works. The first part of the work adds generator capability to the existing 1200A main electrical service. This involves furnishing and installing a new 800A weatherproof automatic transfer switch and a temporary generator connection interface panel, so a portable generator can be connected quickly during an outage. The switch will be tied to the main...
