The Pembrokeshire Demonstration Zone is a new wave energy site located off the South Pembrokeshire coastline.  Wave Hub Limited is the seabed leaseholder.

The zone comprises a 90 sq km area of seabed with water depths of approximately 50 metres and a wave resource of 19 kW/m.  It is located between 13-21kms offshore and has the potential to support the demonstration of wave arrays with a generating capacity of up to 30MW for each project.

The zone is managed by Wave Hub Limited, the operating company for the Wave Hub test site in Cornwall.  Our aim is to help marine energy developers from around the world test in open sea conditions to drive research and innovation, overcome the final hurdles to full commercialisation and foster a growing marine energy industry in the regions we are active in.  

Wave Hub Limited has secured support from the Welsh Government, including the European Regional Development Fund to undertake the following work in 2017:

  • Gain a full understanding of the industry requirements for the wave energy demonstration zone
  • Complete a technical feasibility study and identify an appropriate delivery model
  • Prepare a strong business case for securing funding to enable the zone to be developed
  • Actively engage with key stakeholders


The zone is located in an area with a number of factors that make it ideal for marine energy development:

  • A 400kV transmission line and substation located coastally at the Pembroke Power station
  • World class deep water port facilities and support services provided through the UK’s third busiest port complex
  • An excellent energy sector supply chain and workforce
  • A dedicated, Government backed Energy Enterprise Zone with business development incentives
  • Experience in constructing and deploying Wales’ first tidal stream device
  • Access to expert academic and research facilities
  • An EU Structural Fund Programme for West Wales and the Valleys that has prioritised marine energy


The Pembrokeshire Demonstration Zone could be built by 2020, with the first devices installed in 2021.
