Large-scale batteries work alongside wind farms by storing electricity when the wind is strong and more power is being generated than is immediately needed. That electricity can then be released later when demand is higher, wind generation drops, or there is congestion on the transmission network.
Batteries can also help make renewable energy supply more predictable. For example, they can store electricity during periods of strong wind and release it later to help meet electricity supply commitments to businesses and other large energy users. This is often referred to as “firming” renewable energy.
They also respond very quickly to changes in the electricity system, helping keep the grid stable and reliable.
While batteries cannot store unlimited amounts of electricity, they are an important part of a modern energy system and help make better use of renewable energy.
