WHEN DOES THERMAL STORAGE MAKES SENSE?
• One has high power consuming partial day operation
like office building, process cooling, milk chilling etc.
• One uses DG backup power for more than 3 hours in a
day
• One is expanding / revamping his installation
• Intends to use waste heat / renewable energy sources
