In the world today, electrical consumption is at an all-time high. During certain times of the day, the electrical demand is in so high that power companies have difficulty supplying the required electricity to its consumers. Fortunately, energy storage is becoming a feasible solution for the electrical demand crisis. Simplot is interested in energy storage methods because they are committed to reducing their electrical consumption during peak electrical demand hours. We are designing a process for which Simplot can reduce electrical consumption by storing energy in a warehouse that stores frozen products. This project will include analyzing the heat transfer of the process as well as recommending additional equipment for Simplot’s facilities. The energy storage medium (battery) will be the potato product. The process of storing energy starts by the warehouse chillers lowering the ambient temperature to -12°F during hours when electricity is in low demand. During the chilling process, heat will transfer from the batteries (potato product), and overtime the temperature of the batteries will Approach the ambient temperature (approximately -10°F). During the peak hours, the chillers will be turned off and the temperature of the room and battery will naturally rise the highest allowable temperature (0°F). This senior design process will be used as an energy savings proposal that may be applied to all of the frozen warehouses at Simplot.
