Vattenfall is one half of a joint venture with ScottishPower Renewables to develop the 7.2GW East Anglia Zone.
The company has invested more than £1 million (€1.2 million) to join the OWA and partner with nine other UK wind farm developers that currently have 60% of licensed offshore wind capacity in UK waters.
The £45 million research, development and demonstration programme is an industry collaboration to identify and commercialise innovations that can reduce the costs of offshore wind.
Set up in 2008, the OWA is a joint industry project – involving Vattenfall, E.on, Dong Energy, Mainstream Renewable Power, RWE Innogy, ScottishPower Renewables, SSE Renewables, Statkraft and Statoil - which aims to cut the cost of offshore wind by 10% by 2015.
The OWA is two thirds funded by industry, with the other third coming from the UK Department of Energy and Climate Change. It plans to commercialise innovative ideas in time for use on UK Round 3 wind farms.
