Sembcorp Energy UK is planning on building what it claims will be Europe’s largest battery energy storage system (BESS) at its site at Wilton International on Teesside, in north-east England.

Land and connections are already in place to enable swift installation of the 360MW BESS, with the batteries themselves to be built in tranches, the UK energy industry subsidiary of Singapore’s Sembcorp Group said.

The BESS will form part of Sembcorp Energy UK’s portfolio of battery storage, with the company currently operating 70MW, while a further 50MW is due to be operational in early 2022.
