AES has completed work on a 10 MW energy storage facility at its Kilroot power station in Northern Ireland.

The energy storage array will help balance supply and demand and support the all island transmission grid via system operator, SONI. It will also enhance power supply, enable more efficient dispatch of existing generation assets, and increase the ability to integrate renewable power sources.

The project is the first step in a plan to develop a 100 MW storage array at Kilroot that would be the largest of its kind in the world. It uses 53 000 batteries arranged in 136 separate nodes and is equipped with a control system that can respond to grid changes in less than a second.
