United Illuminating installs energy storage for demand response pilot

Ice Energy installed two Ice Bears energy storage units for Connecticut’s United Illuminating Co. (UI) as a pilot project through the Energize Connecticut initiative to demonstrate the potential of the Ice Bear to reduce peak electric demand.

The Ice Bears were installed at two commercial businesses located in Orange, Connecticut. Each Ice Bear unit was configured to provide both thermal energy storage and demand response.

As a result, at each site, some of the air conditioning load is permanently shifted from peak to off peak using the thermal energy storage and some of it is subject to curtailment in an emergency using the demand response. The pilot will go through this coming summer air conditioning season.

The monitoring and evaluation of the performance of these units is being done in partnership with the University of New Haven’s Tagliatela College of Engineering.

The units were purchased by UI with funds as part of the Energize Connecticut initiative but will be owned by the end customer. This deployment is one of three pilots underway in New England.
