Welsh Resource
1200km coastline wave, wind, tidal stream, tidal
range

Offshore Wind
•Currently 1.3GW operational
around UK (~50% of global total)
•7.2GW in planning or development
•Crown Estate leases (Rnd 3)
totalling 25GW
•Atlantic Array 1.5GW
•Irish Sea 4.2GW
•Three consented off-shore wind farms in
Wales (North Hoyle (60MW), Rhyl Flats
(100MW) and GyM (750MW)

UK Tidal Stream Resource
• DTI Renewable Atlas
• The areas of interest are
yellow and are of peak
flow 2m/s and above
• Resource is located
around the UK and hence
is out of phase
=> Base load
