Presents a quantitative estimate of the market potential of storage cooling systems in terms of the annual electric utility cost savings. A simple methodology was developed to estimate the market potential based on current electric utility rate structures, system first costs, and expected payback periods. The sample group for this study consisted of 40 sites at 22 installations of the US Army Forces Command (FORSCOM). The market potential for the whole Army was extrapolated from the results of the sample group. The results are presented according to three first-cost scenarios - new construction or replacement, retrofit with realistic first costs, and retrofit with upper limit first costs. Sensitivity analysis was performed to reveal the important variables affecting the market potential of storage cooling systems within the Army. Storage cooling system applications for new construction or replacement of cooling plants with payback under five years have the potential to save the Army 5 million dollars annually.KEYWORDS: calculating, marketing, cold sources, energy storage, ice storage, modernising, replacing, payback period, economics, costs, USA, electricity consumption, cost benefit analysis.
