## Summary

Trydan Gwyrdd Cymru, a sub-central government public authority operating under Welsh devolved regulations, is spearheading a significant procurement project titled "Trydan Project Development Services Tender". This initiative covers a variety of professional services required for the development of two wind farms in South Wales. The project's scope includes Environmental Impact Assessment (EIA) Support, Terrestrial Ecology and Ornithology, Planning Support, and Civil Engineering Support. The procurement process has followed an open procedure, with the tender reaching the award stage as of late September 2025. All relevant lots are complete, and contracts have been signed, such as Lot 4 starting from 1st October 2025 and ending in 2028, with potential extensions to 2029. Awards have been given to several suppliers including Mott Macdonald Limited and BSG Ecology Ltd, based on an open procedure focusing on energy-management services.

This project offers substantial business growth opportunities, especially for those in the environmental consulting and civil engineering sectors. Small and medium-sized enterprises (SMEs), as well as larger organisations, were successful in securing contracts, indicating a competitive yet inclusive bidding environment. The initiative is well-suited to firms with expertise in technical and environmental assessments, planning application processes, and innovative infrastructure design. Given the project's location in Wales, businesses with local knowledge or strategic environmental and engineering insights may find particular advantage. The prospect of a potential contract renewal further enhances this opportunity, encouraging ongoing engagement for sustained business impact.
