A number of projects are being developed around the coast of Wales

Developing a world class centre of marine energy in Wales

Anglesey Demonstration Zone

The West Anglesey Tidal Demonstration Zone, known as Morlais, comprises 35km² of sea bed around the promontory of Holy Island with the potential to generate up to 240 MW of energy.

Pembrokeshire Demonstration Zone

The Pembrokeshire Demonstration Zone is a 90km2 area of sea bed being developed for the demonstration of wave and floating offshore wind technologies with a capacity of up to 180MW.

Pembroke Dock Marine

Pembroke Dock Marine is part of the Swansea Bay City Deal and will develop a world class centre for marine energy development, fabrication, testing and deployment.

META (Marine Energy Test Area)

META is a series of pre-consented test sites situated within the relatively sheltered environment of the Milford Haven Waterway in Pembrokeshire. META aims to provide marine energy device developers with an easy access testing facility to de-risk future deployments.


SELKIE is a cross-border project between Wales and Ireland which is working to streamline the commercialisation pathway for the marine renewable energy industry.

Tidal Stream Projects


Minesto are developing their Deep Green project off the coast of Anglesey with a 10MW array. Deep Green is a unique technology that can operate cost effectively in low velocities. They have also established a manufacturing and assembly hall in Holyhead, from which they plan to export devices globally.

Nova Innovation

Nova is developing a 1MW array at Ynys Enlli, building on the success of deploying the world’s first commercial tidal array in Shetland in 2016.

Ramsey Sound

Cambrian Offshore South West Ltd. was set up in 2019 to deliver the Ramsey Sound Regeneration project which will see the regeneration of a tidal energy deployment site, including a grid connected, subsea tidal turbine, sub-station and associated infrastructure.

Tidal Range Projects

North Wales Tidal Energy

The proposed North Wales Tidal Lagoon would stretch 30km from Llandudno to Prestatyn and could deliver vast amounts of renewable energy and jobs to North Wales, as well as providing invaluable coastal protection.

Wave Energy Projects

Bombora Wave Power

Bombora is an Australian wave energy developer that has  has developed an innovative and patented wave energy converter called the mWave. Their full scale prototype is due for deployment at META in 2021 and they plan to establish and manufacture and export hub in Pembrokeshrie.

Marine Power Systems Limited

Marine Power Systems (MPS) Ltd. have developed and tested the WaveSub Wave Energy Converter (WEC) which has undergone sea trials in FaBTest. They are now constructing a full scale prototype which will also function as a floating offshore wind foundation.
