Ameren Illinois Utilities, LED Refrigerated Case Project

Award category


Year released


As part of its Act On Energy Business Program, which provides incentives for energy efficiency projects, Ameren Illinois Utilities partnered with grocery retailer Kroger on a promising application of Light Emitting Diode (LED) lighting technology. After a successful pilot program, Kroger replaced the fluorescent lighting in its refrigerated cases with LEDs at all 30 of its stores in the Ameren Illinois service territory, and beyond. In addition to being more energy efficient, LEDs generate less heat, reducing cooling load. Store installations included motion detectors to further conserve energy. The energy efficiency improvements will provide these Kroger stores with more than $200,000 in annual cost savings. Ameren Illinois provided financial incentives and technical support.
