Technical FAQs 4

What is an energy storage system?

An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.

Why do we need energy storage systems?

When you turn on a hairdryer in your home, somewhere, an electricity generation plant is turning up just a tiny bit to keep the grid in balance. Energy storage systems allow electricity to be stored—and then discharged—at the most strategic times.

What is a battery energy storage system?

Battery energy storage systems (BESS) are charged and discharged with electricity from the grid. Lithium-ion batteries are the dominant form of energy storage today because they hold a charge longer than other types of batteries, are less expensive, and have a smaller footprint. Batteries do not generate power; batteries store power.

How do batteries store energy?

Batteries store energy through electrochemical processes. When a battery energy storage system is charged, electrical energy is converted into chemical energy within the battery cells. During discharge, the chemical energy is converted back into electricity to power devices or supply the grid.
