A full thermal storage system eliminates chiller power during on-peak hours when it is operated as designed. It can also result in significant additional cost savings by decreasing off-peak demand under most utility rate structures that consider demand during the off-peak period. In this paper a method is developed to minimize the utility cost of a full thermal storage system. A case study serves as a demonstration of the method. The concept and approach described will produce similar positive results when applied to typical rate structures in a deregulated or restructured electric energy market.
