The TT2 device features a reinforced concrete gravity base and a steel superstructure supporting two vertical-axis turbines, optimized for efficient transport and deployment. TTL aims to deliver reliable power from medium-energy tidal flows, supporting the commercialization of its next-generation vertical-axis tidal turbine technology. The company is inviting expressions of interest from firms specializing in marine concrete construction, offshore steel fabrication, turbine and electrical component supply, precision mechanical engineering, marine electrical systems integration, offshore transportation, subsea cable installation, and engineering, procurement, and construction (EPC) services for large-scale marine infrastructure.
David Scott, Founding Director at TTL, stated: “This tender represents a major milestone in bringing our innovative tidal energy technology to market. We’re seeking experienced partners who can help us deliver this cutting-edge renewable energy solution that will contribute significantly to the UK’s clean energy targets.”
The prototype is slated for deployment at the Morlais demonstration zone off the coast of North Wales, with construction and assembly planned in Pembroke or Liverpool. Jim Conybeare-Cross, Founder Director at TTL, added: “We’re committed to building strong partnerships with our supply chain. This procurement process has been designed to identify suppliers who can not only meet our technical requirements but also share our vision for advancing tidal energy as a key component of the UK’s renewable energy mix.” Interested companies must submit their expressions of interest to [email protected] by July 4, 2025.
TTL recently joined the UK Marine Energy Council board, with Conybeare-Cross representing the company. The firm plans to install a 2 MW vertical-axis tidal stream turbine at the Morlais site in 2026, followed by a 30 MW project in 2028, with larger arrays under consideration for 2029 and beyond. This initiative supports the UK’s renewable energy goals by harnessing tidal energy to provide sustainable power.
