Hornsea offshore wind farm secures grid connection

The SMart Wind consortium, led by Mainstream Renewable Power and Siemens Project Ventures, has secured grid connection for the first gigawatt of its 4 GW Hornsea offshore wind farm off the Yorkshire coast, UK.

The offshore wind farm will connect to Killingholme substation, an existing 400 kV substation located in the Humber region and owned by National Grid.

Hornsea (Zone 4)

  • Total zone area: 4,735 km²
  • Location: 34-190 km off the Yorkshire coast
  • Water depths: predominantly 30-40 m, with maximum depths to 70 m

The agreement sets out first connection in 2014 and places the project firmly on track to commence construction in 2014 with the remaining 3 GW of the offshore wind farm planned for construction between 2015 and 2020.

Hornsea is one of the three largest zones awarded for development under The Crown Estate’s Round 3 programme in December 2009.

SMart Wind is a 50/50 joint venture between Siemens Project Ventures (SPV) and Mainstream.
