Thermal energy storage tanks take advantage of off-peak energy rates. Water is cooled during hours off-peak periods when there are lower energy rates. That water is then stored in the tank until it''s used to cool facilities during peak hours. This helps reduce overall electric usage by shifting a cooling system''s power consumption from daytime to nighttime.
