Study Confirms 43% Decrease in Energy Consumption with Viking Cold’s TES Technology

Viking Cold Solutions, the leading 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 percent
  • reducing peak demand within this peak period by up to 29 percent
  • maintaining 50 percent 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, VP of Sales & Marketing at Viking Cold Solutions. “With growing demand management challenges and extreme-weather events becoming more common, operators and utilities are in constant search for effective storage and energy efficiency technologies like Thermal Energy Storage.”

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 the following:

  • Reduced average demand 20%
  • Daily peak demand shifted outside of the 13-hour peak period
  • Reduced peak demand between 300 kW and 400 kW 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 Enterprises and Viking Cold are in discussions to deploying additional TES systems in their other cold storage facilities to take advantage of these operational and financial benefits.
