Pembrokeshire provides the highest concentration of wave resource in Wales and has significant tidal streams.  Wales’ first tidal stream device was deployed off the coast of Pembrokeshire.

In addition to the excellent energy resource that Pembrokeshire offers, there are a number of other factors that set the area apart from other UK and Welsh sites and provide an attractive package for potential investors. These include excellent port facilities and transferable skills, grid connection possibilities, funding, world class research, a history of collaborative working in the marine sector and the haven waterway enterprise zone offering competitive operating costs for businesses.

The Pembrokeshire Wave Demonstration Zone is located 13 km off the South Pembrokeshire coast. Third Party Management for the site is a collaborative approach being led by Wave Hub with partners including Marine Energy Pembrokeshire and Pembroke Port.

The zone has the potential to support the demonstration of wave arrays with a generating capacity of up to 30MW for each project.

Marine Energy

Marine energy is about harnessing the energy from the sea – including waves, tidal streams and tidal range – to generate electricity. Wave energy refers to the act of harnessing and using energy that is produced by surface waves from the ocean. Tidal stream energy makes use of the kinetic energy of moving water to power turbines. Tidal range energy make use of the potential energy in the difference in height (or head) between high and low tides. Pembrokeshire has huge potential to assist in the national and international drive to lower our reliance on fossil fuels and move towards a low carbon future through the use of its abundant marine renewable energy resources.
