Greenfield has received regulatory clearance to proceed with the construction of a 400 MW battery energy storage system in East Yorkshire, England. The project marks one of the largest standalone battery storage facilities in the UK, targeting grid stabilization and renewable energy integration. Located near Hull, the facility will support National Grid’s efforts to balance supply and demand amid rising intermittent renewable generation. Construction is expected to commence in Q3 2026, with commercial operations anticipated by mid-2028. The development aligns with the UK government’s 2035 net-zero targets and the country’s push to deploy 30 GW of battery storage capacity by 2030. No financial details or offtake agreements have been disclosed in the announcement.
