UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

The Welsh Government is currently in the planning stage for the Bro Tathan Power Project, aimed at enhancing energy infrastructure at the strategic employment and innovation site located at St Athan in the Vale of Glamorgan. This project is part of the Cardiff Airport and St Athan Enterprise Zone, pivotal for regional growth. Meetings with interested organisations are planned for March and April 2026 to discuss the legal and commercial principles of the project, with the procurement process expected to commence at the end of April 2026. The competitive flexible procedure under the Procurement Act 2023 will be employed for the tender process, seeking to establish a joint venture with a private-sector partner. The project involves significant construction work and public utilities, with a planned budget of £42,000,000 and a contract period from March 2027 to September 2029.

This tender creates substantial opportunities for independent distribution network operators, independent connection providers, funders, and infrastructure operators who are ready to engage in a collaborative joint venture with the Welsh Government. Businesses specialising in construction, public utilities, installation services, and energy sources will find this project particularly lucrative, offering expansive growth potential at a site with major occupiers like Aston Martin Lagonda and access to key transport routes. The competitive procedure under the Procurement Act 2023 allows for flexibility, innovative procurement models, and market alignment, maximising the chances for successful project delivery and fostering high-value inward investment. Interested parties are encouraged to express interest and participate in market engagement to refine legal and commercial approaches ahead of formal procurement.

Notice Title

Bro Tathan Power

Notice Description

The Welsh Government is providing potential market participants with early notice of the forthcoming Bro Tathan Power Project procurement. This notice and Memorandum of Information (MOI) provides preliminary details in respect of the background, objectives and intended delivery approach for the Project, to enable interested organisations to consider and prepare for the formal tender process, which is expected to commence in at the end of April2026. The information contained within this notice and MOI is provided for awareness only. It does not constitute a call for competition, nor does it commit the Welsh Government to proceed with any procurement. Bro Tathan is a 1,200-acre strategic employment and innovation site located at St Athan in the Vale of Glamorgan (Bro Tathan Site). The Bro Tathan Site forms part of the Cardiff Airport and St Athan Enterprise Zone, a key driver for regional growth. The Bro Tathan Site benefits from exceptional connectivity - just five miles from Cardiff Airport and directly linked to the M4 corridor via the Northern Access Road (Ffordd Bro Tathan). It also features a fully operational 1,800-metre runway with airside access. Bro Tathan is already home to major occupiers such as Aston Martin Lagonda, eCube Solutions and Caerdav, and offers capacity for over3 million sq ft of additional development across its designated zones (West, East, North, South and Y Porth). Each zone of the Bro Tathan Site will support advanced manufacturing, aerospace, R&D and commercial employment uses. The Welsh Government has invested extensively in enabling infrastructure and site servicing, positioning Bro Tathan as a ready-to-invest platform for high-value inward investment. The Project is central to this long-term vision, delivering the energy capacity and resilience needed to attract and sustain occupiers at the Bro Tathan Site. Connecting the Bro Tathan Site to the National Grid Electricity Transmission network via new 132kV circuits and a substation, the Project will help realise Bro Tathan's potential as a nationally significant location for investment, innovation and sustainable industrial growth. The intention is for the Project to be delivered through a Joint Venture (JV) between the Welsh Government and a private-sector partner. The JV will be responsible for the design, build, finance, operation and maintenance of the network infrastructure required to deliver up to 280 MVA of capacity to the Bro Tathan Site. The forthcoming procurement will seek to select a single consortium capable of providing the full range of expertise required for successful delivery of the Project. The Welsh Government intends to launch the Project procurement through the Competitive Flexible Procedure under the Procurement Act 2023. Further information in relation to the anticipated procurement process (including an indicative timetable) can be found in the MOI.
