InterGen secures PPA for 320 MW Gateway Battery Energy Storage System (BESS) in Essex

InterGen’s 320 MW Gateway battery storage project on the Thames Estuary has been awarded a 15-year agreement to supply the UK with power in the Government’s recent Capacity Market auction, run by the Department of Business, Energy and Industrial Strategy (BEIS) to ensure a reliable supply across the grid at the lowest cost to customers.

The award represents a significant milestone for the GBP200 million (US$222.5 million) project which first gained planning consent from BEIS in November 2020. Construction will commence in 2023 and the project will initially provide a minimum of 320 MW of decarbonised electricity to over 300,000 homes and businesses, with the potential to grow up to 450 MW.
