Benefits of Thermal Storage• Reduced Demand Charges - $350/kW annually• Reduced electricity costs

o Can switch to ConEd’s SC-9 Rate II and save 1.5 cents/kWh on Deliveryo Negotiate add’l Retail savings from reduced on-peak power purchase

• Thanks to DMP, we are seeing 3.5 year paybacks on retrofit projectso One of the few times in Calmac’s history that we are recommending

retrofit applications where there’s no chiller replacement or capacity constraint

• Additional redundancy and resiliency• Simple operation: plug-and-play with bldg. controls• Long life: 35+ year expected lifespan

o Polyethylene: no erosion, no corrosion; same material as natgas pipelineso Our earliest tanks from 1980 are still operating today
