Axiom Exergy is set to install $5 million worth of refrigerator battery systems in supermarkets and other cold storage facilities in Brooklyn and Queens, New York.
Axiom's refrigeration battery system is designed to reduce a supermarket's peak power use by up to 40 percent and provide backup cooling during power outages. It uses the excess capacity of a customer's existing refrigeration system to "store cooling" at night by freezing a tank of salt water. The frozen tanks supply refrigeration to the building during peak afternoon hours, eliminating the need to run energy-intensive compressors and condensers.
The businesses are eligible for incentives under Consolidated Edison's Neighborhood Program.
"We're thrilled to see that Con Edison is taking an innovative approach to help address surging power demand on its grid by working with grocery store and cold storage facility owners to reduce their energy bills and enhance their razor-thin profit margins," said Amrit Robbins, Axiom president. "By deploying refrigeration battery systems, these locations can convert power-hungry refrigeration systems into intelligent 'batteries' that can respond dynamically to the needs of the facility and the grid operator, taking into account energy prices, weather patterns, and grid programs like demand response."
