New Taco Thermal Energy Storage (TES) tanks play a role in shifting energy loads and helping commercial buildings meet decarbonization goals. The tanks are typically used for emergency backup of data center chilled water-cooling systems. Taco stratified TES tanks store water in distinct temperature layers. By leveraging TES, data centers can ensure that cooling systems remain operational during power failures, prevent overheating, and reduce the risk of service disruption during emergency situations. TES tanks offer scalable and cost-effective solutions for data center operators seeking to improve cooling resilience, reliability, energy efficiency, and long-term operational stability.  As data centers continue to grow in scale and importance, the adoption of TES for emergency backup cooling will play a crucial role in ensuring the continued success and sustainability of modern IT infrastructure.
