The Aberdeenshire Bay project is being developed by a Vattenfall-led consortium in Aberdeen Bay to test next-generation wind turbines. Trump is opposed to the project as he believes they will spoil the view from a golf course he is building nearby. The offshore project is currently going through the permitting process, while Trump has ordered work on the golf course to be stopped.
According to the The Herald, Trump is planning to work alongside anti-wind group Communities Against Turbines Scotland (Cats). Trump Organisation managing director George Sorial said the Trump will back Cats financially.
The issue puts the Scottish government in a difficult position. Although renewable energy is a keystone of the ruling Scottish National Party's policy, the party's leader and Scottish first minister Alex Salmond has previously thrown his weight behind Trump's plans.
Sorial said: "We are very serious about our position and our concern that Scotland is being encircled with these monstrous turbines. We intend to use all our resources to fight these proposals."
It is the latest in a long campaign by Trump against the project, which he has previously described in a letter to Scottish first minister Alex Salmond as "useless eyesore" and said the 11-turbine project would be "disastrous and environmentally irresponsible."
Sorial pointed out that Scotland's great links golf courses are being threatened by the development of wind energy. "All the great links golf courses, that people from all over the world have enjoyed for centuries, are now being threatened."
In response WWF Scotland head of policy Dan Barlow said: "Given the urgent need to tackle climate change it is deeply depressing to hear in detail how Donald Trump intends using his vast wealth to try to kill-off one of the clean, green solutions available to the people of Scotland."
