CONTACT A TRANE EXPERT

Trane Thermal Battery™ systems are premier HVAC plants designed to be a distributed resource for our changing grid. Their ability to store thermal energy can make your buildings more profitable, sustainable and grid-resilient.

How our Systems Work

Trane Thermal Battery systems are Trane-controlled chiller plants enhanced with thermal energy storage. The chiller plant operates like a battery: charging when excess or inexpensive energy is available, or when outdoor conditions improve efficiency, and discharging when demand is high, price is high or when the utility or grid operator asks for help meeting capacity.

  • Financial Savings

    Reduce peak electricity load and shift energy use to less expensive and more efficient off-peak periods.

  • Higher Sustainability

    Lower dependency on more emissive fossil fuels

  • Stronger Resiliency

    Optimize building operation for changing grid conditions

Learn more about two of our Thermal Battery System offerings below.

Thermal Battery Air-Cooled Chiller Plant

The Trane® Thermal Battery air-cooled chiller plant is a thermal energy storage system which can make installation simpler and more repeatable, helping to save on design time and construction cost.

  • Advantage: To streamline the design and user experience; Reduce water usage 
  • Ideal for: Building owners with limited plant operation staffing; Engineers looking to offer advanced system performance without additional design time

Thermal Battery Heat Pump

The Thermal Battery™ Storage Source Heat Pump system builds on the benefits of thermal energy storage for cooling and extends its benefits to heating. Water-cooled chillers charge CALMAC energy storage tanks which store and recover energy for delivering heating and cooling.

  • Advantage: Recovers energy from previous day to offset or eliminate new energy for heating
  • Ideal for: Building owners and engineers looking to decarbonize and meet new electrification building codes
