MADRID, Spain  Mainstream Renewable Power and Ocean Winds, the joint venture between EDPR and ENGIE, are teaming up to develop their second 500-MW ScotWind site east of Shetland in the northern UK North Sea.

This will expand the footprint of the Arven offshore wind farm to 2.3 GW.

The first 1.8-GW site was issued to the 50:50 joint venture between Mainstream and Ocean Winds last year under the ScotWind leasing process, with Ocean Winds separately awarded a 500-MW site in the same NE1 Block.

Mainstream has now acquired a 50% share in Ocean Wind’s holding company, and the parties are now developing the two sites jointly.

They are also developing a 1.2-GW floating offshore wind farm in South Korea and are in a consortium for Norway’s upcoming Utsira Nord floating offshore wind tender in the North Sea.

For Arven, they have started the local engagement process, holding meetings with supply chain partners, local authorities and fisheries representatives.

Last month Ocean Winds and partner Ignitis Renewables submitted the highest development fee, Eur20 million ($21.7 million), at the tender for the 700-MW Lithuanian offshore wind project.

They expected to be announced as the provisional winners of the tender for the development of power plants in the maritime area and to then set up a joint company, which will be awarded the development and operation permit conferring the right to use the maritime area for 41 years.

The 120-sq-km offshore wind farm development area is 30-36 km from Lithuania’s Baltic Sea coast, The development should generate up to 3 TWh/year of electricity, equivalent to up to one-quarter of the country’s current needs.
