While the price of energy storage continues to drop, battery performance, driven by emerging technologies, grows stronger. Today's energy storage systems monitor and adjust battery discharge in a manner that mitigates high demand charges. Typically, an energy storage installation will lead to somewhere between 20% and 50% in "demand charge" savings for commercial utility usage. Battery-backed emergency power systems that protect against utility outages and a more reliable community grid are two important additional benefits to implementing a storage system.
