The Department of Business, Energy and Industrial Strategy (BEIS) in the UK has given the green light to the country’s biggest ever battery storage project.
InterGen has gained planning permission for a 320MW/640MWh lithium-ion battery site at DP World London Gateway, a new port and logistics centre on the Thames Estuary in Essex, south-east England. The £200 million (US$267 million) project will also have the potential for further expanding, as far as 1.3GWh.
Fluence is providing the technology for the site, having worked in partnership with InterGen for the past two years following a competitive tender process. The companies initially signed an exclusivity agreement for another project at Spalding, which was since been extended to the Gateway project.
According to the company, this puts it at 10 times the size of the largest battery currently operating in the UK. Indeed, it will dwarf the UK’s biggest active project so far, the 50MW/75MWh Thurcroft battery storage site in South Yorkshire, which was recently acquired by stock exchange listed specialist fund Gresham House Energy Storage.
In terms of international context, the world’s largest battery project already under development is Vistra Energy’s Moss Landing project in California, which is permitted for an eventual 400MW/1,600MWh, to be built in phases. The world’s largest project in operation today is the Gateway project developed by LS Power, also in California. That project is currently at 230MW output and 230MWh capacity, as of August, with a further expansion to 250MW/250MWh already underway. Australian utility AGL recently said it is planning a 250MW battery storage project with up to 1,000MWh of capacity, while The Red Sea Development Company, developing a huge luxury resort in Saudi Arabia said last week that it plans to use 1,000MWh of battery storage to integrate local renewable energy resources.
Construction of the DP World London Gateway is expected to get under way in 2022, and the battery to become operational in 2024. Additionally, InterGen is looking to develop another large scale battery project at its site in Spalding, Lincolnshire. This would be a 175MW/350MWh site, and planning permission is already in place. The Edinburgh-headquartered independent energy generator currently supplies around 5% of the UK’s generating capacity, with natural gas sites in Coryton in Essex (800MW), Spalding in Lincolnshire (1,250MW) and Rocksavage in Cheshire (810MW).
