The Worset Lane Battery Energy Storage  project is located outside the village of Hart on the outskirts of Hartlepool. The project is on land adjacent to National Grid’s 275kV Hartmoor substation. It will connect directly to the High Voltage transmission line carrying electricity from east to west across the north of England. 

It occupies an ideal position on the grid to future proof the electricity transmission network for the connection of more off-shore wind farms in the North Sea. Just to the east are the on-shore substations for a number of planned off-shore wind farms including Dogger Bank C. It is one hop from the main 400kV transmission line bringing electricity from Scotland’s off-shore wind farms down to demand centres in England. 

Project overview



Currently used for cereal planting the site already hosts a number of migratory and non-migratory birds in hedgerow to the north of the field. The project includes a range of ecological enhancement designed to support existing and attract new birds while encouraging growth in insects and mammals. 

650 metres of new hedgerow planting will both screen the batteries from a nearby footpath and, along with two acres of newly created woodland areas, act as new habitats for birds and mammals. A new wetland meadow to the north of the site will encourage new insects, amphibians and water mammals. 

A further 7 acres of wildflower meadow planting will provide food for insects, bees and butterflies. Bird, bat and insect boxes will be installed around the site to provide additional habitats. Altogether these new features should increase biodiversity across the site by 90%.
