Energy storage refers to technologies capable of storing electricity generated at one time for later use. These technologies can store energy in a variety of forms including as electrical, mechanical, electrochemical or thermal energy. Storage is an important resource that can provide system flexibility and better align the supply of variable renewable energy with demand by shifting the
What is grid-scale battery storage? Battery storage is a technology that enables power system operators and utilities to store energy for later use. A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time
