EIA scoping report submitted for the Pembrokeshire Demonstration Zone

Wave Hub Limited (WHL) has today submitted an environmental scoping report to Natural Resources Wales and the Marine Management Organisation for the Pembrokeshire Demonstration Zone (PDZ).  The report considers a mix of wave energy and floating wind technology with a maximum total electricity generation of 100MW and asks for a formal opinion on what issues should be covered by an Environmental Impact Assessment (EIA).   

The Pembrokeshire Demonstration Zone is an offshore site leased by The Crown Estate to WHL for the deployment of large scale wave energy arrays.  The site is 90 sq km, located approximately 15km off the South Pembrokeshire coastline and the proposed onshore grid connection is at Pembroke Dock Power Station.  It is the only planned wave energy site in Welsh waters.

This is an important milestone for the Pembrokeshire Demonstration Zone and marine energy in Wales. The feasibility study commissioned by WHL has concluded there would be a benefit in sharing the PDZ site and grid infrastructure with a more commercially developed project. Floating wind is developing rapidly and there are very few existing demonstration sites for this technology in the UK. We know the PDZ would be a good location to test floating wind as it has a good wind resource and the water depth is suitable for most types of floating wind technology. We have received a lot of interest from developers looking for sites to deploy at. By sharing the PDZ with floating wind we will be able to broaden access to finance for the project, bring forward development of the site and enable a phased installation of technology that will support commercialisation of both the wave and floating wind sectors.

Madeline Cowley, the PDZ Project Manager

The development of wave technology in Wales has already achieved significant milestones, with two devices now built and undergoing initial sea trials. Key to achieving commercial success is the test and demonstration of this technology at scale in real sea conditions and at a grid connected site. The PDZ will provide the necessary infrastructure for this technology to be demonstrated in Welsh waters, building on the Marine Energy Test Area we are also developing in the Haven.

David Jones, the Marine Energy Wales Project Director

The Scoping Opinion will determine which key issues the EIA should focus on and what environmental surveys need to be undertaken.   A consent application could be submitted in 2020, consent granted in 2022 and the first electricity could be generated by 2024.

Notes to Editors

Wave Hub Ltd is the operating company of Wave Hub, the offshore renewable energy test site off the north coast of Cornwall, with offices in Hayle and Pembroke Dock.

The Pembrokeshire Demonstration Zone is leased by Wave Hub Ltd from The Crown Estate.

The Zone comprises a 90 sq km area of seabed with water depths of approximately 50 metres, a wave resource of 19 kW/m and a wind resource of 10m/s.

Wave Hub Ltd secured support in 2017 from the Welsh Government, including the European Regional Development Fund, to undertake a feasibility study to:

  • Gain a full understanding of the industry requirements for the demonstration zone;
  • Develop an outline engineering design and identify an appropriate delivery model;
  • Prepare a strong business case for securing funding to enable the zone to be developed; and
  • Actively engage with key stakeholders.
