Quinbrook & E.ON to construct 460MWh UK battery

March 19, 2024

Quinbrook Infrastructure Partners has entered into a partnership with E.ON to construct a 230MW/460MWh battery energy storage system at Uskmouth in South Wales in the UK.

E.ON will acquire 50 per cent of the project capacity and jointly invest in its construction, a statement said.

Quinbrook acquired the exclusive development rights for the project in June 2022 and since then has secured planning approvals and grid import agreements with National Grid, as well as completing project design and equipment procurement.

The project is expected to be operational in Q1 2025.

Quinbrook affiliate Private Energy Partners undertook the design and project development phases, led equipment procurement and will manage construction for the project on behalf of the joint venture.

“E.ON shares our commitment to sustainable development goals and recognises the meaningful impact that large scale regeneration projects like Uskmouth, a former coal power station stockyard, can make to the delivery of the Government’s Levelling Up ambitions,” said Keith Gains, managing director and UK regional lead for Quinbrook. “We are pleased to welcome E.ON as a partner and look forward to working together to complete construction of this milestone project, which will be a key contributor to achieving the UK’s net zero targets.”

Chris Norbury, E.ON UK chief executive, added: “This is a massive investment for E.ON in the UK’s energy system and an important recognition of the enormous potential for battery solutions in the UK. Battery energy storage sites will play a significant role in the future of the nation’s power provision and specifically in supporting ever greater sources of renewable energy. Battery plants around the country can allow us to make best use of all renewable energy sources by harnessing the energy and having it ready for use whenever it’s needed – increasing the share of renewable energy on the grid, helping secure supplies on the grid and making energy more affordable for our customers.”
