Pembrokeshire Wave Demonstration Zone

The Pembrokeshire Demonstration Zone (PDZ) is a 90km2 area of sea leased from the Crown Estate by Wave Hub Ltd, the operating company of the Wave Hub test site in Cornwall. The PDZ is located between 15 and 21 kilometres off the south Pembrokeshire coast with water depths of between 50-62 metres. It has the potential to support three wave energy arrays of up to 30MW generating capacity each, together with a pre-commercial 90MW floating wind demonstration project. The site benefits from a 19 kW/m wave resource and 10 m/s wind resource. It also offers excellent grid connection possibilities, including 132kV transmission line and substation
located on the coast, along with world-class deepwater port facilities and support services.

A feasibility study was completed in 2018 and the Environmental Impact Assessment process has started. Detailed design and environmental surveys are planned to start in 2019 to enable a consent application to be submitted in 2021.

Wave Hub Ltd has an office in the Marine Energy Hub in Pembroke Dock and plans to recruit two full time members of staff in 2019. Wave Hub Ltd is working in partnership with the Port of Milford Haven, Offshore Renewable Energy Catapult and Marine Energy Wales to secure this funding and deliver the project over the next 5 years.
