- The 320MW/640 MWh storage facility is expected to be the largest in the world when completed and would be capable of supplying electricity to 300,000 homes for two hours.
- The project will be deployed by InterGen and is slated to come online by 2024, and will be located in Essex.
U.K. energy company InterGen has been granted planning approval for the deployment of the world’s largest storage project by the Department for Business, Energy and Industrial Strategy (BEIS). The 320MW/640 MWh storage facility is expected to cost £200 million. It will be deployed at the DP World London Gateway, a logistics park on the banks of the Thames in Essex.
The storage system will provide back up power and system balancing with an initial two-hour duration. According to InterGen, the battery, when fully charged, could provide power up to 300,000 homes for two hours. But the company expects that the bulk of its use will be as a support and for stabilising existing electricity supply. The storage system is also expandable to 1.3GWh.
Project completion is slated for 2024 and construction set to commence in 2022. The company also stated its plan for a second energy storage system with a capacity of 175MW/350 MWh in Spalding, Lincolnshire spending approval.
