The Potomac Electric Power Company (PEPCO) is actively studying methods, such as Thermal Energy Storage (TES), to reduce the summer peak growth rate. TES is a technology that can provide significant reductions in the summer on-peak demand level thereby aiding building owners in reducing their operating costs while helping utilities reduce summer peak load growth. From analysis of PEPCO's chilled water storage system in its Forestville, MD office building it is evident that for demand reduction to be achieved significant consideration must be placed in the operational strategies chosen for the TES system. The chiller priority strategy was chosen because it is straightforward to implement and provides security that stored chilled water will always be available. The building, operating under the chiller priority scenario, accomplished a maximum load reduction 20 kW in 1985 and an average summer season load reduction of 13.5 kW. Demand reductions of up to 50 kW were expected but not achieved largely due to the operational strategies chosen. An alternative approach is storage priority. If storage priority had been implemented for the 1985 cooling season, analysis indicate that the expected demand reductions of 50 kW could have been achieved. 7 figures, 2 tables.
