The addition of stratified chilled water storage to the Cornell chilled water system has increased its capacity and efficiency and reduced its operating costs for less than the cost of a conventional chilled water plant expansion. The other new component of the storage facility - two variable speed drive thermal storage transfer pumps - saved energy by allowing adjustment to the lower system head without throttling. The first-year operating cost savings exceeded $300,000 - $235,000 due to demand shift and time of use savings, and the remainder from the impact of thermal storage on overall system performance.
