    Brief

    The Welsh Government is seeking a private-sector partner for a Joint Venture to design, build, finance, operate and maintain electricity network infrastructure for the Bro Tathan strategic employment site near Cardiff. The project will connect the 1,200-acre Bro Tathan Site to the National Grid via new 132kV circuits and a substation, delivering up to 280 MVA of capacity to support advanced manufacturing, aerospace, and innovation uses. The site currently hosts major occupiers including Aston Martin Lagonda and offers over 3 million square feet of development capacity. This is an early market notice for interested organisations to prepare for the formal tender process, which will be launched under the Procurement Act 2023 Competitive Flexible Procedure in late April 2026. The selected consortium will need expertise across design, engineering, financing, grid connection, and long-term asset management. This is a preliminary notification only and does not commit the Welsh Government to proceed.
