The Viking Cold Thermal Energy Storage (TES) technology stores thermal energy at night by freezing food-safe Phase Change Material (PCM) specially formulated to freeze at -18°F. The refrigeration equipment then runs significantly less during peak hours, and the freezer “rides” the PCM to maintain stable temperatures and protect the food. The TES provides energy and cost savings for customers with industrial freezers, such as Bashas’, and also provides long-term benefits to all SRP customers by reducing peak demand.
The project was a result of a partnership between SRP, Viking Cold Solutions and Bashas’ Family of Stores. SRP is collaborating with Arizona State University’s School of Sustainable Engineering and the Built Environment, along with Nexant’s Utility Services Group, to measure the results of the project. Results will be used to extrapolate the potential impact of this technology on additional low-temperature refrigeration loads in the Phoenix area.
