SAE achieves planning milestone for its AW1 Battery Storage project at the Uskmouth Sustainable Energy Park

SAE is pleased to announce that it has discharged all of its pre-commencement planning conditions for the 120MW/240MWh Battery Storage project known as Afon Wysg 1 ("AW1") at the Uskmouth Sustainable Energy Park. This will be the first Battery Storage project developed by SAE that it will build, own and operate. The delivery of the AW1 project is key to unlocking one of the largest battery sites in the UK and unlocking significant growth and economic opportunity for the local region.

SAE's team worked closely with Wales-based civil engineering business Jones Bros Civil Engineering UK and industry-leading engineering specialists Tetra Tech, Inc. to discharge the conditions.

SAE would like to thank the world-leading teams involved with this project and the team at Newport City Council for their ongoing support.

With this milestone achieved, SAE is working towards financial close for the project, which it will update the market on in due course.
