Viking Cold’s long-duration Thermal Energy Storage (TES) technology sits behind the meter and leverages the heat transference properties of phase change material, intelligent controls, and 24/7 monitoring and reporting software to reduce energy consumption and shift time-of-use for up to 13 hours per day while better maintaining stable freezer temperatures to safeguard frozen product.
This happens because the TES systems allow the energy-intensive refrigeration equipment to be turned off for long periods of time during peak periods, or at times when renewable energy sources go offline, to flatten out demand spikes. TES now provides utilities access to the enormous load of the cold storage industry for additional grid capacity and resiliency. This newly accessible load helps utilities delay costly infrastructure projects and provides a path to engagement with commercial and industrial customers. Viking Colds TES technology has been tested, accepted, and incentivized in many utilities projects across North America (Southern California Edison, San Diego Gas & Electric, Pacific Gas & Electric, Eversource, more), and our systems are installed and running in multiple countries.
