Utility chooses Ice Energy’s energy storage solution to reduce peak demand

Windsor, Colo., August 25, 2009 — Ice Energy, a provider of distributed energy storage and smart grid solutions, agreed with Redding Electric Utility to provide the California-based utility with its Ice Bear distributed energy storage system to permanently reduce peak summer electrical demand.

REU, the City of Redding’s locally owned and controlled municipal utility, selected Ice Energy’s storage solution to slow the growth of peak demand and reduce the utility’s exposure to costly peak power.

By changing how and when energy is consumed for air conditioning, 1,000 Ice Bear units installed in REU territory would enable the utility to reduce its peak power demand by as much as 7 MW, more than offsetting its planned peak load growth.

Redding’s summer weather is dominated by hot, dry sunny days, driving the demand for REU’s electricity to provide air conditioned comfort. Evening temperatures drop by as much as 40 degrees; as temperatures fall so does the demand for and cost of power. Ice Energy’s solution enables REU to leverage the abundance of less expensive off-peak power and offset the need to run fossil fuel burning power plants during the peak of the day.

For businesses and building owners, this means reduced daytime energy consumption, lower energy costs, and a smaller environmental footprint, with no operational or behavioral change to negatively impact customer comfort or economic productivity.
