DOE Includes Thermal Energy Storage As Energy-Efficient Option
The alert notes that TES differs from traditional space cooling systems because it does not rely on electric chillers operating during peak demand periods when electricity rates are higher. Instead, chillers are used during off-peak periods, when rates are lower, to store ice or chilled water in insulated tanks for use the next day.
