“Turbines are magnets for lightning which is why they are fitted with conductors to transfer the energy to the ground but they can cause significant damage. Blades can explode; generators and control system electronics can incinerate. “The repair of lightning damage can be dangerous and expensive.
Cables from Hornsea Three would come ashore at Weybourne, while cables from Vattenfall’s two wind farms would reach Norfolk at Happisburgh. Both would then need trenches up to 60 kilometres long to be dug across the Norfolk countryside to connect them to the National Grid. Mr Freeman said he was not against the principle of wind farms ...But he said he felt local communities had not been properly engaged with and the siting of a substation the size of Wembley Stadium at Necton was inappropriate.
A controversial offshore windfarm which will provide power for thousands of homes could be rubber-stamped by planners next week.
A new mammoth offshore wind project has applied for Marine Scotland consent off the north-east coast of Scotland.
The Scottish division of the Royal Society for the Protection of Birds (RSPB) has hit out against a study published today on the risk to seabirds through collision with offshore wind turbines, calling the findings a “very optimistic interpretation of data”.
The energy firm behind one of the world’s biggest offshore wind farms has scrapped plans to build large electricity plants in the Norfolk countryside. Vattenfall, which wants to build two wind farms around 50 kilometres off the east Norfolk coast, said today it will use more advanced technology which will mean a cable corridor it hopes to dig across the Norfolk countryside will be narrower. It also means no relay stations will be needed.
The new report prepared by economics professor Gordon Hughes, a former advisor to World Bank, Dr Capell Aris, a fellow of the IET, and Dr John Constable of the Global Warming Policy Forum, explains how the broad assumption that offshore wind prices are falling is not valid. Through a detailed statistical analysis of the data, covering 86 wind farms, the authors found that capital cost of offshore wind (£/MWh installed) is actually rising as a consequence of companies moving into deeper and deeper waters. The summary of the report is provided below. The full report can be downloaded from this page.
The document claims that ‘it has been widely assumed that the underlying costs of offshore wind are falling and that the CfD prices indicate a sudden paradigm for the technology’. Yet, the report points to statistical analysis of the data, covering 86 wind farms, which suggests that the capital cost of offshore wind (£/MWh installed) is not in actual fact falling, but actually rising as a consequence of companies moving into deeper and deeper waters.
Up to 11 years of building work could be needed to bring wind farm cables ashore in Norfolk - sparking a call for businesses to be compensated.
The English Supreme Court is due to hear an appeal on the long-running dispute in connection with the Robin Rigg Offshore Wind Farm. ...At issue is whether E.ON (the employer) or Højgaard (the contractor) must bear the approximate €26 million cost of remedying failed grouted connections between monopiles and transition pieces at Robin Rigg.
Yesterday planning consent for the floating development was granted and announced by Holyrood’s minister for Business, Innovation and Energy, Paul Wheelhouse MSP. But some local residents fear the enormous turbines could spoil the picturesque views from Stonehaven and the nearby Dunnottar Castle.
The Technology and Construction Court in London has ruled that cracking discovered on some of the 140 monopiles built by Shanghai Zhenhua Heavy Industries Ltd (ZPMC) for the Greater Gabbard offshore wind farm ”was largely a result of various failures by ZPMC to maintain correct preheat temperature of the welds to the monopiles.”
This paper argues that the methods and data used when estimating effects of offshore wind turbines on seabird population rates and the potential impacts on seabird populations are grossly inadequate. As a result, Environmental Impact Assessments cannot solely be relied on to report risks. The conclusions cited in the paper are provided below.

The delay follows the decision by Theresa May to abolish the energy department and fold it into a new Business Energy and Industrial Strategy department after she became prime minister following the Brexit vote.
Scottish Ministers and two offshore wind developers will appeal against court rulings that seek to void planning permission for as much as 2.3 gigawatts of new renewable energy capacity.
Dong Energy has cancelled its plans to build a base port at the Able Marine Energy Park (Amep) on the River Humber, northeast UK, as it could not "justify the investment".
A legal challenge from RSPB Scotland to the granting of consent for four major offshore wind farms has been upheld. The bird protection charity had objected to the Scottish Government’s consent for the developments in the Forth and Tay regions.
"The constant, extremely loud thudding 'heartbeat' late into the night, night after night from pile driving the new crop of these monsters is hardly evidence of whoever is behind this scheme showing any consideration for the residents of Wirral. "These wind farms are rapidly becoming an ugly blot on what is otherwise a beautiful view along the Wirral coastline."
Developer Dong Energy, which is majority-owned by the Danish state, said it had taken a final decision to proceed with the 1.2 gigawatt project that would be capable of powering one million homes and create 2,000 jobs during construction.
