World’s largest battery project gets approval in the UK

The Department for Business, Energy and Industrial Strategy (BEIS) has granted planning approval to the deployment of what will be the world’s largest storage project when completed – a 320 MW/640 MWh storage complex under development by U.K. energy company InterGen.

The £200 million ($266 million) project is planned to be deployed at the DP World London Gateway, which is a logistics park located on the banks of the Thames in Essex. The storage system, which the company said could be expanded to 1.3 GWh, is expected to provide fast-reacting power and system balancing with an initial two-hour duration. “When fully charged, the battery could power up to 300,000 homes for two hours,” the company said. “However, it will mostly be used to support and stabilize existing electricity supplies.”

The huge facility is expected to come online in 2024, with construction being scheduled to start in 2022. No more technical or financial details on the project were provided. It stated, however, that a second large battery project with a capacity of 175 MW/350 MWh is being planned near Spalding, in Lincolnshire, and that approval is still pending.
