Welcome to Llywelyn

floating offshore wind farm

About

Located in Welsh waters off the coast of Pembrokeshire, Llywelyn wind farm will provide 300MW of clean, zero-carbon renewable energy capacity to South Wales.

Llywelyn wind farm, along with its sister project in Cornish waters, Petroc, will be among the first commercial-scale floating offshore wind projects in the UK, using the next generation in clean renewable offshore energy technology. Cutting-edge floating wind technology will enable Llywelyn to be located in deeper water, and further offshore, minimising visual and environmental impacts while taking full advantage of stronger and more consistent winds.

300MW installed capacity

20 turbines

40 miles offshore

232,000 homes served*

*Equivalent of 232,392 homes, calculated as the installed capacity (300MW), multiplied by BEIS’s “all wind” (onshore & offshore) load factor expressed as a fraction of 1 (0.3164) multiplied by the number of hours in a year (8,760), divided by the average annual domestic electricity consumption expressed in KWh (3,578).

The Celtic Sea

With excellent wind resource, suitable water depth and a requirement for new electricity generation, the Celtic Sea is highly attractive to floating wind development. The region offers a unique opportunity to unlock new clean energy capacity and help establish a new industrial sector. To date, these waters have seen comparatively little offshore infrastructure deployment.

Llywelyn is one of two cutting-edge floating offshore wind projects developed by Falck Renewables and BlueFloat Energy in the Celtic Sea. Together with Petroc, these projects could contribute up to 600MW of renewable energy capacity to South Wales and South West England, and deliver most of the UK’s 1GW floating offshore wind target by 2030. You can read more about Petroc here.

Site location

Llywelyn wind farm is located in Welsh waters in the Celtic Sea, 40 miles off the coast of Pembrokeshire.

Llywelyn’s location has been selected following an extensive feasibility study and rigorous site assessment process. Our assessment has included reviews of protected areas, environmental impacts, cable routing, existing infrastructure, marine traffic, and fishing activity.

We have signed an agreement with National Grid, securing a 300MW grid connection in Pembrokeshire. The system operator is exploring upgrades to the existing site to facilitate the connection.  These developments will enable the Llywelyn offshore wind project to quickly enter the planning system.
