The electric grid managers went into a panic the very first time the air conditioners were turned on at the Arizona Diamondbacks' new Bank One Ballpark (1998; BoB is now called "Chase Field" [1]). The stadium people didn't realize they needed to let the electric utility know that they would suddenly be adding hundreds of kilowatts of electric power draw to the grid. Some years later a chilled water plant was built to use off-peak electricity to chill a million gallons of water/antifreeze [2]. This is used to cool about 30 buildings in downtown Phoenix. Ever since I heard about the ballpark's system, I wanted one for myself. This "IceBear" system looks promising.
