What is a battery energy storage system?

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 to provide electricity or other grid services when needed.

Are lithium-ion batteries a viable energy storage system?

That cost reduction has made lithium-ion batteries a practical way to store large amounts of electrical energy from renewable resources and has resulted in the development of extremely large grid-scale storage systems. These modern EES systems are characterized by rated power in megawatts (MW) and energy storage capacity in megawatt-hours (MWh).
