Case Study AT A GLANCE Shortly before Hurricane Katrina hit New Orleans, WinnDixie Stores enacted a program that rebuilds damaged grocery stores in the event of a natural disaster. Winn-Dixie selected Cummins Power Generation to help them with the rebuilding process after the hurricane. In October 2007, the Winn-Dixie store in New Orleans East reopened and became the first full-service grocery store to return to the community. Cummins Power Generation provided a 600 kW diesel generator to provide electricity to the entire store in the event of a power outage. Fully compliant with NFPA 110 for Level 1 systems, the generator provides the Winn-Dixie store with a graphical data display. The display allows the operator to view all engine and alternator data; perform operator adjustments for speed, voltage, and time delays; view fault history; and set up and adjust the generator set. The standby generator features a PowerCommand iWatch wireless monitoring system that links the generator set with cellular and satellite networks. Winn-Dixie users can access operational data using the Internet or receive e-mails or text messages about alarm condition updates. The standby generator, equipped with automatic transfer switches and a 3,600-gal, sub-base fuel tank, sits atop an 8-ft-high, floodprotected platform.
