A cooling system and method are provided which include a facility cooling unit, a cooling tower, and one or more thermal capacitor units. The facility cooling unit, which includes a heat dissipation coolant loop, facilitates thermal energy extraction from a facility, such as a data center, for expelling of the energy to coolant within the heat dissipation coolant loop. The cooling tower is in fluid communication with the coolant loop, and includes a liquid-to-air heat exchanger for expelling thermal energy from coolant of the heat dissipation coolant loop to the surrounding environment. The thermal capacitor unit is in fluid communication with the heat dissipation coolant loop to facilitate efficient thermal energy transfer from coolant with in the coolant loop to the surrounding environment with variation in ambient temperature about the cooling tower.
