Thermal energy storage (TES) is the storage of for later reuse. Employing widely different technologies, it allows thermal energy to be stored for hours, days, or months. Scale both of storage and use vary from small to large – from individual processes to district, town, or region. Usage examples are the balancing of energy demand between daytime and nighttime, storing summer.
