The giant offshore substation for Iberdrola-owned ScottishPower Renewables’ (SPR) 714MW East Anglia 1 (EA1) wind farm has been successfully installed in the southern North Sea, some 59km off eastern England.

The 6,800 tonne substation – christened Andalucia 2 at Navantia’s Puerto Real shipyard in Cadiz in early July – will play a central role in the £2.5bn
