Encorp Automatic Transfer Switch Ensures Reliable Power and Cost Savings for Food Distributor NOBEL/SYSCO, the Rocky Mountain region's largest food service distributor, wanted to ensure production of its 17,000 items - from frozen foods to gourmet items - continued round-the-clock at its 430,000 square foot facility in Denver. Even a brief power outage would have a resounding impact on the 24-hour operation -- orders might not be filled for the 7,000+ restaurants, hotels, schools, hospitals and other firms this $350 million company serves. NOBEL/SYSCO needed a safety net to ensure power reliability, so the company installed two Cummins/Onan generator sets: a 750kW DFHA and a 1500kw DFLE to provide back-up power in the event of a power outage. However, after talking to representatives at Xcel Energy, the local utility, NOBEL/SYSCO learned about the substantial cost savings possible through the utility's curtailable-rate program. This innovative program allows Xcel Energy to periodically ask NOBEL/SYSCO to turn on its back-up generators and use power only from the generators - not the utility - during times of peak energy use. The program is a win-win for NOBEL/SYSCO and Xcel: NOBEL/SYSCO can reduce its utility bill thousands of dollars each month (up to a 12 percent reduction each month) and Xcel can ensure it has an additional 2 MW of electricity available to serve customers during peak times. To participate in the curtailable-rate program, however, NOBEL/SYSCO needed additional equipment to ensure a seamless transition from utility power to generator power. The company contracted with Encorp to supply two Automatic Transfer Switches (ATS 4000), which instantaneously transfer NOBEL/SYSCO's facility loads of 1,200 and 2,500 amps to the generators, and two Encorp Utility Power Controls™, which provide safe, reliable transfer of power between each generator and the utility grid. The Encorp equipment also ensures seamless transitions of power when it's time for NOBEL/SYSCO to return to utility power. The technology neutral Encorp equipment easily interfaces with an Andover Control system already in place at NOBEL/SYSCO. The Andover Control system is a complete building-automation system that monitors security, lighting and other electrical services on site. |
