Thermal Energy Storage (TES) System

  • Expands capacity of the existing chilled water system
  • Saves utility costs
  • Reduces the need for new electrical generating facilities

  • Underground tank holds 3 million gallons of chilled water (for use in air conditioning systems in UPC buildings)
  • System uses existing chiller plants
  • Chillers run at night to cool the water, when electricity is cheapest
  • Chilled water from the tank is used during daytime hours, when electricity is most expensive
