Case study: CKE Restaurants' defrost controller pilot

This case study from the U.S. Department of Energy explores how CKE Restaurants, in collaboration with Southern California Edison's New Products Development and Launch organization, field tested an advanced demand defrost control system for walk-in coolers and freezers in their Carl's Jr. restaurants. 

The company, which owns, operates, and franchises some of the most popular brands in the quick-service restaurant industry, including Carl's Jr. and Hardee's, says the technology deployment advances its commitment to cutting energy waste. The case study of the 2015 pilot estimated that if the control system is installed on CKE's freezers at 150 Carl’s Jr. restaurants, savings would be approximately 390,000 kWh annually (about $58,500). For the coolers, savings would be approximately 150,000 kWh annually (about $22,500).
