DR Potential of Residential Appliances - Refrigerator (LG)

The overarching Demand Response (DR) Appliance project is aimed at three types of residential appliances: refrigerators, dishwashers, and clothes washers. This report focuses on refrigerators manufactured by LG Electronics. Concurrent with this project, the U.S. Environmental Protection Agency began investigating the optimal way to incorporate DR capability into its Energy Star appliance labeling programs. In the proposed language, DR capabilities are defined in response to “Spinning Reserve” events (those with a duration <10 minutes) or “Delay Load” events (those with duration >10 minutes and <4 hours), following an industry-devised protocol. Discrepancies exist between utility objectives, the event definitions, and appliance reactions. Findings from these projects will be used to help inform interested parties during the development process of DR capabilities and protocols.
