Study shows TES cuts energy usage for cold storage operations

Viking Cold Solutions, a Thermal Energy Storage (TES) provider for the low-temperature cold storage industry, announced that its measurement and verification (M&V) study on Viking Cold’s TES technology at Dreisbach Enterprises’ 93,000-square-foot frozen food distribution center in Richmond CA shows significant operational and financial benefits for utilities and the cold storage industry.

The study demonstrated the ability of TES to mitigate the facility’s 13-hour peak period by simultaneously:

•Reducing peak period energy consumption by up to 43%.

•Reducing peak demand within this period by up to 29%.

•Maintaining 50% more stable temperatures.

Refrigeration is the third-highest electricity-consuming utility category, and the cold storage industry is a prime target for load distribution management solutions. Cold storage operators, the grocery industry, and utilities challenged with managing peak loads on the electrical grid can all benefit from the refrigeration efficiency and load shift capabilities of TES.

“This study demonstrates that cold storage operators can safely reduce energy costs and utilities can significantly lower demand on the electrical grid during peak periods to defer costly infrastructure investments,” said Collin Coker, vice president of sales and marketing at Viking Cold.

Post-study PG&E load analyses validated the study results. For each of the subsequent three months beyond the test period, year-over-year comparisons of demand showed:

•Reduced average demand by 20%.

•Daily peak demand shifted outside of the 13-hour peak period.

*Reduced peak demand between 300 and 400 kilowatts for the entire 13 hours

These results were achieved with a decrease in maximum demand while better maintaining the facility’s temperature requirements.

Based on these successes, Dreisbach and Viking Cold are in discussions to deploy additional TES systems in Dreisbach’s other cold storage facilities to take advantage of these operational and financial benefits.
