Please click the link below for the Welsh version.

Pen y Cymoedd Wind Farm is located in South Wales. Its 76 turbines became operational in 2017 and can produce enough electricity to power 15% of Welsh homes annually. In addition to the production of fossil free electricity, a 22MW battery is co-located at the wind farm.

The battery is able to respond to the needs of the grid system in less than a second, supporting a stable supply of electricity to UK homes.
