New submarine power plants are heading for the coast off North Wales.
Sweden’s leading marine energy developer Minesto today introduced a new range of power plants – the Dragon Class – an improved design of the company’s Deep Green technology for predictable renewable electricity generation from currents of tidal and oceanic.
Offering increased performance and reduced manufacturing costs, the Dragon class will be delivered and installed in all of Minesto’s ongoing projects as well as in the construction of the company’s first network projects.

This includes at Holyhead Deep off the west coast of Anglesey – the world’s first low-flow tidal current project.
Minesto’s long-term plan is to expand the Holyhead Deep site to an 80 MW commercial tidal network.
“We are delighted to announce this latest development of our unique technology. The Dragon class evolves from the systems we installed and operated in our Faroe Islands project. Its added value for the customer goes straight to the point: maximizing performance and minimizing costs. This is the backbone of our ongoing business expansion, ”said Dr Martin Edlund, CEO of Minesto.
Through Computational Fluid Dynamics (CFD) modeling, ocean-scale model testing, and operational data from DG100 units connected to the grid at Vestmannasund, Minesto’s technology development team was able to improve the conversion of energy and at the same time refine the power plant by reducing the number of subsystems and components of the power plant.
With the Dragon class, Minesto is also strengthening its patent portfolio, as innovations related to improved design have resulted in new patent applications.
Mr. Edlund added, “The design of the Dragon class results in significantly higher power generation performance and by reducing the number of components we also reduce manufacturing and assembly costs.
“Additionally, it simplifies handling during installation and maintenance, which is crucial as we now extend the technology to megawatt-sized power plants for commercial installations. “
The design of the Dragon class is evolving efficiently and will be available in various sizes and wattage ratings suitable for maximum performance depending on site conditions such as flow rate and water depth.
Mr Edlund added: “ We are in the procurement and manufacturing phase of five Dragon-class power plants for large-scale (1.2 MW) and smaller micro-grid installations.
“These will be delivered and installed in our current projects in France, Wales and the Faroe Islands. We are pleased with the progress made on these projects and they are on time and on budget.
