SAE and Econergy International Ltd have entered a strategic joint venture (JV) to co-develop the AW2 250 MW battery storage project at SAE’s Uskmouth Sustainable Energy Park (USEP).
This partnership brings together two leaders in the renewable energy space, combining SAE’s experience in developing complex renewable energy generation and battery storage projects in the UK and its ownership of the highly strategic USEP site with Econergy’s deep expertise in battery storage construction, financing, and execution. Their combined experience ensures the project is well-positioned to move through the planning process and toward financial closure.
As battery technology continues to progress, the team is designing the project for a duration of up to five hours, bringing the project’s total potential capacity to 1250 MWh. The project aims to achieve planning permission within the next 12 months and financial close in 2027.
The AW2 project will be the third battery storage project to be delivered at the USEP, which is one of the leading battery storage sites in the UK, with over 1 GW of projects either in construction or development.
SAE CEO, Graham Reid, commented: “This partnership is an ideal fit for both parties and for the project. We have a clear strategy to be an independent power producer, and we are delighted to be partnering with a company that has the same strategy. We look forward to working with Econergy to deliver this exciting project for our businesses, the community and our shareholders.”
Econergy Head of Energy Storage, Joshua Murphy, added: “This JV with SAE marks a strategic milestone in Econergy’s continued expansion in the UK energy storage market. As we scale our energy storage portfolio across Europe, the AW2 project reflects our commitment to building critical infrastructure that supports the UK’s grid stability. Partnering with SAE at one of the UK’s most advanced energy hubs reinforces our ambition to be a leading force in delivering flexible, reliable, and sustainable power solutions.”
