A recent study of a frozen food centre demonstrated a 43-per-cent reduction in peak-period energy consumption using a Viking Cold solution.
A measurement and veriﬁcation (M&V) study on Viking Cold’s Thermal Energy Storage (TES) technology at Dreisbach Enterprises’s 93,000-square-foot frozen food distribution centre in Richmond, California showed signiﬁcant operational and ﬁnancial beneﬁts for utilities and the cold storage industry. The system was able to reduce peak period energy consumption by up to 43 per cent; reduce peak demand within this peak period by up to 29 per cent; and, maintain 50 per cent 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 shows 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.
Post-study load analyses validated the study results. Each of the three months beyond the test period showed reduced average demand by 20 per cent; daily peak demand shifted outside of the 13-hour peak period; and reduced peak demand between 300kW and 400 kW for the entire 13 hours.
Dreisbach Enterprises and Viking Cold are in discussions to deploy TES systems in more Dreisbach cold storage facilities to take advantage of these operational and ﬁnancial beneﬁts.
