Con Edison reduces peak demand with battery storage

US power utility Con Edison partnered with energy storage firm Axiom Exergy to reduce power demand during peak periods and help owners of businesses decrease bills.

In a press statement, the utility company said it will commit $5 million towards installation of Axiom Exergy’s thermal energy storage system in supermarkets and cold storage facilities in Brooklyn and Queens.

The initiative falls under the utility’s Neighborhood Programme and aims to help businesses manage energy usage, avoid food spoilage and help ensure grid stability.

In total, the project will install between 1.5MW and 2MW refrigeration battery storage systems and is expected to save 6MWh to 8MWh of energy during peak periods.

Con Edison will provide incentives to participants of the programme.

[quote] Amrit Robbins, president of Axiom Exergy, commented: “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.”

Energy battery storage and power demand

The solutions provider claims that its technology will help consumers reduce their peak electricity demand by 40%.

The refrigeration battery system stores a refrigerator’s excess capacity, make use of it to freeze a tank of salt water, store the cooling and use the frozen tanks to supply refrigeration services to buildings during peak periods.

During scheduled demand response periods, the solutions provider can remotely activate the refrigeration battery systems using its cloud platform Axiom KARL.

The system has the ability to provide facility operators and Con Edison with real-time fleet performance monitoring, data analytics, and alerts, adding intelligence to refrigeration equipment.

Greg Elcock, manager of the programme at Con Edison, added: “By working with customers in the Neighborhood Programme area to help them use energy more efficiently, we have been able to keep service reliable during another hot New York summer. [Con Edison signs new demand response programmes].

“We will continue to help customers in these sections of Brooklyn and Queens choose from a variety of technologies and energy options that will help them manage their usage.”
