Study Confirms 43% Decrease in Energy Consumption in an Ammonia-Refrigerated Warehouse with Viking Cold Solutions' Thermal Energy Storage Technology – Significant Benefits for Cold Storage Owners and Grid Operators


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 and 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 by 20 percent
  • daily peak demand shifted outside of the 13-hour peak period
  • reduced peak demand between 300kW 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 deploy additional TES systems in Dreisbach Enterprises'
other cold storage facilities to take advantage of these operational and
financial benefits.
