Newport council approves 250MW battery storage project at Uskmouth

LONDON - Ampeak Energy Limited and Econergy International Limited have received formal planning permission from Newport City Council for a 250MW battery storage project at the Uskmouth Sustainable Energy Park (USEP), according to a press release statement.

The Afon Wysg 2 (AW2) project is designed for a duration of up to 5 hours, potentially providing a total capacity of 1,250 MWh. The formal decision notice follows the initial approval at the planning committee meeting on October 1, 2025.

The project will be the third battery storage facility at the USEP site, which the companies describe as one of the UK’s leading battery storage locations. The planning permission includes conditions for the removal of pulverized fuel ash.

Econergy, which operates the 50MW Swangate project and has 360MWh of additional battery energy storage systems under construction expected to come online in 2026, is partnering with Ampeak Energy on this development.

For Ampeak Energy, the AW2 project, combined with its MeyBESS project in Caithness, Scotland, represents 2.45 GWh of battery storage capacity. This marks a significant expansion from the company’s 240MWh AW1 project.

The joint venture partners are now preparing the AW2 project for financing and construction, with financial close scheduled for 2027.
