Moray Offshore Renewables is a joint venture between Spanish oil company Repsol and Portuguese power company Energias de Portugal. China's stated-owned Three Gorges Corp. recently acquired 21 percent of EDP from the Portuguese government. Three Gorges led the construction of China's environmentally destructive Three Gorges Dam - the world's largest hydroelectric plant.
Moray must first receive planning permission, which is not a certainty.
If the scheme goes as planned, it would be larger than the London Array, 1-gigawatt off shore wind farm under construction in the Thames Estuary which if completed by the target year 2015 would be the world's largest.
