A High Court judge has overturned the decision last year by then business and energy secretary, Alok Sharma, to award a development consent order for the 1.8GW Norfolk Vanguard offshore windfarm being developed by Vattenfall. The judge said the secretary of state had acted unlawfully by failing to provide adequate justification for declining to consider the cumulative impacts of the onshore infrastructure for Norfolk Vanguard and its 1.8GW sister project, Norfolk Boreas, when granting planning permission for the former.
