Maximizing value in application stacking via battery analytics

May 30, 2020 | Case Study

Application stacking in energy storage system (ESS) markets creates multiple revenue streams for a single energy storage system by providing different grid services. While stationary energy storage has historically been more expensive than energy storage for transportation, application stacking favorably changes the economics to create a profitable asset where a singular value stream wouldn't merit deployment. Batteries used in application stacking are subject to a variety of charge and discharge cycles, each of which affect battery health and state of charge differently. Tracking that usage to optimize battery performance across applications has the potential to further reduce the levelized cost of storage (LCOS) by managing battery maintenance across uses for prolonged system lifetime.
