Dell Children's Thermal Energy Storage

Client: Austin Energy
Location: Austin, Texas


Burns & McDonnell designed and built the 880,000-gallon stratified chilled water tank, sized to meet the four-hour peak reduction to take advantage of the local utility rate structure. The tank also provides increased redundancy and reliability of the chilled water system serving the Dell Children's Medical Center. The TES tank allows for increased flexibility by being able to charge the tank with electric centrifugal chillers or using steam from the on-site combined heat and power system to operate a two-stage absorption chiller. The Steel Tank Institute recognized the TES tank as the Steel Tank of the Year in the special storage category.
