Designing a Thermal Energy Storage Program for Electric Utilities

Abstract

Electric utilities are looking at thermal energy storage technology as a viable demand side management (DSM) option. In order for this DSM measure to be effective, it must be incorporated into a workable, well-structured utility program. This paper describes a methodology to design a successful thermal energy storage program for electric utilities. The design process is addressed beginning with the market research phase. The research includes information obtained from utilities having successful thermal storage programs. In addition, information is gathered from interviews with local architects and engineers, air conditioning contractors and potential thermal energy storage customers. From this information a marketing plan is developed that addresses the target market, market penetration, promotional methods, incentive types and levels, internal and external training requirements and optimal organizational structure. The marketing plan also includes various rate structures, program procedures and evaluation techniques. In addition to the marketing plan, several case histories are addressed.
