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.”
