Ice Energy has a novel solution for the electricity challenges of the 21st century: Make Popsicles.
Put another way, the company wants to freeze water at night in refrigerator-like boxes adjacent to commercial air conditioners and then thaw it during the day, when power demand is highest. This would theoretically allow AC-hungry commercial buildings in warm climates to cut energy use during heat waves, by shutting air conditioners down while still providing cool air to buildings from melting ice.
After seven years of development and testing, the Windsor, Colo.-based company signed an agreement recently with the Southern California Public Power Authority here to deploy some 6,000 Popsicle-making units at 1,500 locations in the utility's service territory around Los Angeles. Ice Energy says the units, called Ice Bears, will lead to a 30 percent fuel reduction for the utility through avoided use of so-called peaker generation plants, which are only turned on when demand is highest.
