What is a battery energy storage system?

Battery Energy Storage Systems (BESS) are crucial for the energy transition, providing flexibility and stability to the grid. They store energy from renewable sources like solar and wind, and release it when needed, helping to balance supply and demand. In the UK we are due to energise our first two UK batteries, based in Scotland, in spring 2025.
