Thorpe Marsh Green Energy Hub

Thorpe Marsh Green Energy Hub is a battery energy storage system currently under construction around 4 miles (6.4 km) north of Doncaster, near the villages of Thorpe in Balne and Barnby Dun, in South Yorkshire, England. It is situated on a brownfield site between the remnants of Thorpe Marsh Power Station to the east, and the Yorkshire Wildlife Trust's Thorpe Marsh Nature Reserve to the west. When completed, the energy hub will be the largest of its kind in the United Kingdom, and one of the largest in Europe and the world, being capable of storing up to 3.1 GWh (11 TJ) of energy at a power of 1.4 GW. This, however, does not make it the UK's largest energy storage site, which, as of September 2025, is Dinorwig Power Station in north Wales, with a capacity of 9.1 GWh (33 TJ). Thorpe Marsh is expected to be capable of exporting 2,000 GWh (7,200 TJ) to the grid per annum.
