J.C. Penney HQ shaves energy costs with one of world’s largest ice storage systems
J.C. Penney’s corporate headquarters in Plano, Texas, saved more than $100,000 in 2015 by using an ice-based energy storage. The system, IceBank from Calmac, is one of the largest in the world, producing and storing nearly 4MW of cooling or 2.4 million pounds of ice each night. The technology has been in place at the retailer’s 1.8 million sq.-ft. headquarters for 25 years. Due to its design, it is still as efficient now as the first day it was incorporated.
