"Evaluating an Ice-Storage System in a Deregulated Environment"
Author: Staniewicz, Theodore J., and Joseph J. Watson

Date: January/February 2001

Discusses the implications of the deregulation of the electric industry, particularly for those with ice-storage systems.  Draws from experences at St. Joseph's University in Philadelphia, which was designing a School of Business classroom and conference center, with a thermal ice storage system as part of the HVAC design.  Reviews design, analysis, implementation, and monitoring and validation processes.  Analysis revealed that cost of the additional energy expended to manufacture ice was greater than the savings available by shifting load to off peak, resulting in the decision to eliminate the automatic ice-making mode and allow it be energized manually.
