Technology Potential of Thermal Energy Storage (TES) Systems in Federal Facilities
Thermal energy storage reduces electric costs by shifting chilling activities to off-peak times. Water is chilled or ice is made during the night to either replace or augment operation of cooling equipment during the day. Off-peak demand and consumption rates produce significant dollar savings. TES requires favorable electric rate structures, available space to house the associated equipment, and either variation in buildings cooling loads or favorable climatic conditions. TES can be implemented anywhere cooling loads can be shifted to off-peak hours with the best applications being office buildings, hospitals, and schools. Most TES projects are implemented in conjunction with an existing cooling system expansion, replacement of older cooling equipment, or new construction, thus reducing energy costs, consumption, and demand. Various options are available for funding TES projects in Federal facilities, including direct agency funding, capital improvement funds, utility financing, and alternative financing. The Federal Energy Management Program (FEMP) should promote TES through demonstrations, success stories, and by distributing the FEMP Technology Alert (March 2000). Federal Facilities should, as standard practice, evaluate TES options whenever a chiller retrofit or replacement is performed.
