For many Army installations, the electrical demand charge of their utility bills can be as high as 50 percent of the total bill. One effective way to reduce peak electrical demand and electrical utility costs is by use of storage cooling systems. To curb the anticipated growing cost of the electrical utility at Fort Jackson, the engineers at the Directorate of Public Works (DPW), Fort Jackson, decided to install a 2.25M-gal capacity chilled water storage (CWS) cooling system for the Energy Plant No. 2, which serves more than half of the Fort's cooling load. During the first year operation (1996-1997), the system saved about $0.43M in electrical utility bill charges from reduced on-peak electrical demand and reduced energy consumption for cooling. This report documents the design, construction, operation, and performance of the system.
