Planning permission granted for world’s largest battery energy storage scheme
Planning permission has been granted for the world’s largest battery energy storage scheme (BESS), a 1GW (1040MW/2080MWh) project located at the Trafford Low Carbon Energy Park in Greater Manchester.

Planning permission for Carlton Power’s £750m BESS was granted by Trafford Council.
Subject to a final investment decision, construction of the battery storage scheme is expected to begin in the first quarter of 2024. Commercial operations are expected to start in the final quarter of 2025. Carlton Power said it is in advanced talks with companies to finance, build and operate the Trafford BESS.
The Trafford BESS joins Carlton’s 200MW Trafford Green Hydrogen scheme whose £50m first phase (15-20MW) is also set to enter commercial operation in the fourth quarter of 2025.
In a statement, councillor Tom Ross, leader of Trafford Council and Green City-Region lead for Greater Manchester, said: “The Trafford BESS, alongside the Trafford Green Hydrogen scheme, places Trafford and Greater Manchester at the forefront of the UK’s energy transition. The two schemes will help address our climate crisis – one of Trafford Council’s corporate priorities - and will support our region’s plan to reach a target of net zero carbon emissions by 2038.”
