Series A · Berkeley, California · founded 2013 · 20 employees$10.1Mraised▾
Thermal battery system for Commercial power consumers. The platform provides turnkey energy-management solutions that reduce operational costs and business risk for supermarkets and commercial buildings with high refrigeration-based energy loads. The primary product is a solution that uses existing refrigeration systems in a commercial building or supermarkets to store thermal energy during off-peak hours and deploys it during peak hours. As a result, electricity demand is claimed to be reduced by up to 40 per cent during peak hours. The Refrigeration Battery provides both load-shifting that offsets costly on-peak electricity charges and on-demand backup cooling when power fails. The solution is controlled through backend software which optimizes the Refrigeration Battery’s charge cycle by storing refrigeration when energy costs are lowest and providing cooling services at peak consumption periods.
