The Sundon Battery Energy Storage project will be one of the first sites to connect under the National Grid’s Energy Park programme.

This innovative partnership between National Grid and renewable energy developers is designed to quickly and cost-effectively add battery storage to the transmission network to capture the full potential of existing renewable energy generation assets.   

The site is adjacent to the National Grid 400kV substation at Sundon on the high voltage transmission line between offshore wind generation in the North of England and the distribution circuit that supplies electricity to London. 


Biodiversity benefits

The site includes a 7 metre buffer of new shrub and tree planting which both screens the batteries from a nearby public footpath and encourages biodiversity gain in a predominantly arable area.

Planting will be a diverse mix of native British species. Bird and insect boxes will be installed along the site boundary to support a range of bird and insect species.
