The new site, situated east of Shetland, is projected to add 500MW to the capacity of the Arven Offshore Wind Farm, increasing its overall footprint to a substantial 2.3GW.
The Arven Offshore Wind Farm comprises two distinct locations.
The first encompasses a 1.8GW site situated east of the Shetland Islands, secured through a 50:50 joint venture between Mainstream and Ocean Winds during the ScotWind leasing process in 2022.
Additionally, Ocean Winds obtained a 500MW site within the same NE1 block.
With Mainstream’s completion of a 50% share acquisition in Ocean Wind’s holding company, these two sites are now under joint development, with the aim to fully maximise their potential.
