Marine Energy Wales


Marine Energy Wales is a partnership between technology developers, the supply chain, academia and the public sector working in collaboration to establish Wales as a “centre of excellence” for sustainable marine energy generation.

The vision is to create a thriving and diverse sustainable marine energy industry, making a significant contribution to a low carbon economy. The benefits of this industry are felt throughout the entire supply chain creating green sustainable jobs, growth and skills.

With €100.4 million of EU structural funding prioritised for marine energy in Wales over the next 5 years, two wave and tidal stream Demonstration Zones, seabed agreements in place for three separate wave and tidal stream projects, and a number of proposals for significant tidal range projects, Wales is well positioned to play a global leading role in marine energy.


Over 100 MPs urge government to back tidal lagoons

More than 100 MPs from all parties have urged the government to make a swift decision in favour of pressing ahead with the Swansea Bay tidal lagoon project, which was endorsed by former Conservative energy minister Charles Hendry in last month's Hendry Review on Tidal...

Marine Energy Wales’ reaction to Minesto Expansion

Press release: 15/02/2017 Last week it was announced that Minesto intend to scale up their Holyhead Deep project by increasing the planned installation of their tidal array to 80MW. A scoping report has been submitted to Natural Resources Wales following the...

The country has a number of factors that make it an ideal location for marine energy development with up to 6.2GW (over 10GW including the Severn Estuary) of estimated generating capacity:


  • €100.4 million of funding prioritised for marine energy in Wales
  • An indicative wave capacity of up to 5600MW
  • Tidal streams of up to 4ms-1
  • Long term, dedicated political support from Welsh Government
  • The potential for 8,720MW installed capacty from four tidal lagoons
  • 400kV transmission lines and substations located coastally at resources areas
  • Array scale Demonstration Zones in Anglesey and Pembrokeshire
  • Eight strategically located ports sited along the North, West and South coast
  • Energy sector supply chains and workforce with huge transferable skill opportunities
  • Experience in constructing and deploying Wales’ first tidal stream device
  • Dedicated, Government backed Energy Enterprise Zones with business development incentives
  • Access to expert academic and research facilities
  • Marine Energy Wales providing a single point of access for marine energy developers interested in Wales
  • Supportive Government policy including world leading legislation e.g. Well-being Future Generations Act

What People Say About Us

“The formation of this pan-Wales body to drive forward the industry and encourage collaboration between all the interested parties is very timely and very welcome. The renewable marine energy sector has real potential for Wales which is a key location for the development and deployment of new innovative technologies. We need to ensure we are in pole position to maximise these opportunities, attract investment and create jobs and Marine Energy Wales has an important role to play in helping us achieve this.”

Ken Skates AM, Cabinet Secretary for Economy and Infrastructure

“The Marine Energy Wales team has done a fantastic job helping to push forward marine energy in Wales, bringing together all of the key players, and getting marine energy up the political agenda. Having been involved in developing marine energy projects in Wales for over 10 years now, I have certainly appreciated the support they have provided, and this active support network is clearly something that sets Wales apart.”

Joseph Kidd, Commerical Manager, Nova Innovation Ltd

“This partnership provides a unique opportunity for the long-term development of the marine renewables industry in Wales, will create a number of jobs in Pembrokeshire and will help to put Wales at the forefront of marine energy development.”

Chris Williams, Development Director for Tidal Energy Ltd

”It is too difficult to build a new industry on your own. Developers, suppliers and public actors in marine energy has to work closely together to secure the path towards commercial breakthrough. Marine Energy Wales is the driver and enabler of such collaboration and thus plays a vital role for Minesto to succeed in our number one market, Wales.”

Dr Martin Edlund, CEO, Minesto

“In 2013 Ledwood Mechanical Engineering Limited celebrate 30 years of operations based in Pembroke. Our extensive skills gained through maturity of delivering diverse projects has enabled us to gain entry into the renewable sector. Our location is well suited for the future tidal and wave generating investment opportunities. Working with key stakeholders such as MEW will potentially allow us to gain market share and promote business sustainability & growth.”

Nick Revell, Managing Director, Ledwood Mechanical Engineering Limited

“For us the seminars provide a fantastic opportunity to engage with like-minded people and supply chain companies, after all we are looking to build an industry in Wales and the event give us the chance to meet people who have similar aspirations, and who want to be a part of the supply chain for us.”

Ioan Jenkins, Development Director, Tidal Lagoon Swansea Bay

“Marine Energy is a critically important component of Wales future economy. We are delighted to play an important role in Marine Energy Wales.”

GERALLT LLEWELYN JONES, Managing Director, Morlais
