A GREEN energy project which faced legal challenges from Donald Trump has passed a milestone with the installation of the final device.

Bosses at Vattenfall confirmed the last of the 11 turbines – the world’s most powerful – at its European Offshore Wind Deployment Centre (EOWDC) off Aberdeen has been put in place.

It is the first commercial project to use a new style of foundations, each of which weigh almost as much as 10 Boeing 747 aircraft. The giant turbines are 191m tall, with each blade 80m. The 164m rotor has a circumference larger than that of the London Eye.

The Aberdeen Bay development will be Scotland’s largest offshore wind test and demonstration facility and will trial next generation technology.

But it has been hit by delays, including legal challenges from Donald Trump who claimed the turbines would ruin the views from his golf course at Balmedie.

It is now scheduled to start generating power this summer, and should produce the equivalent of more than 70% of Aberdeen’s domestic electricity demand.
