Plan for $25 billion North Sea ‘ring main’ to power oil and gas via floating wind



Plans for a £20 billion ($25 billion) floating wind-powered North Sea “ring main” transmission network have been unveiled by the biggest winner in Scotland’s pioneering auction to electrify offshore oil and gas production using renewables.

Cerulean Winds and development partner Frontier Power claim their North Sea Renewables Grid (NSRG) in the central North Sea could be one of the UK’s largest-ever infrastructure projects, offering a “plug-in” option for hydrocarbons.

With 3 gigawatts across three sites, Cerulean was the largest single winner in the INTOG leasing round held by Crown Estate Scotland to spur North Sea green electrification.
