The objective of this project was to determine the savings in utility operating costs that could be obtained by installing a Battery Energy Storage System (BESS). The target utility was Kansas City Power and Light (KCPL), a typical Midwestern utility with a mix of generating plants and many interconnections. The following applications of battery energy storage were modeled using an Electric Power Research Institute (EPRI) developed and supported program called DYNASTORE: (1) Spinning Reserve Only (2) Load Leveling with Spinning Reserve (3) Load Leveling Only (4) Frequency Control DYNASTORE commits energy storage units along with generating units and calculates operating costs with and without energy storage, so that savings can be estimated. Typical weeks of hourly load data are used to make up a yearly load profile. For this study, the BESS power ranged from ``small`` to 300 MW (greater than the spinning reserve requirement). BESS storage time ranged from 1 to 8 hours duration (to cover the time-width of most peaks). Savings in operating costs were calculated for each of many sizes of MW capacity and duration. Graphs were plotted to enable the reader to readily see what size of BESS affords the greatest savings in operating costs.
