The consortium, which includes fund management company Equitix, was selected ahead of competition from Blue Transmission (a consortium of Macquarie Capital Group, Barclays Infrastructure Funds Management and Mitsubishi Corporation), National Grid Offshore and Transmission Capital Partners (a consortium of Transmission Capital Partners and International Public Partnerships).
The value of the transmission asset is believed to be EUR 346 million. The third round will take place later this year.
Earlier this month, Gwynt Y Mor wind project moved a step closer to completion with the installation of its four subsea export cables.
The cables have been buried in the seabed between the platforms 16 kilometres off the coast of north Wales and the Pensarn beach in Conwy county.
The EUR 2 billion project, a joint venture between RWE Innogy (60%), Stadtwerke München (30%) and Siemens (10%), is one of the largest offshore wind farms currently in construction in Europe. Power will be generated by 160 Siemens 3.6MW turbines, which are due to be fully operational in late 2014.
