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.
German wind developer Wpd has filed a complaint to Germany’s constitutional court against the Wind Energy at Sea Act (WindSeeG) after its far-offshore project Kaikas in the North Sea was excluded from future offshore wind tenders without compensation to the developer.
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.
It remains unclear if offshore wind can be a steady moneymaker without government support, which besides tax credits and minimum rates can include guaranteed access to power grids. “It should be the ambition of everybody to not have subsidies,” Ms. Bosman of Shell said.
”Parliament has made it clear that Sweden’s ambitions are to improve its defense. Hanöbukten is one of the strategically most important defense areas Sweden has. The government has considered this issue carefully and have concluded that in this case it is not possible to combine the defense business with wind turbines.”
SWEDEN: The area is considered a strategic training area for the armed forces and the Government has decided that in this case the planned wind power operation cannot be combined with the Armed Forces' activities.
Longitude Engineering, a specialist marine engineering subsidiary of the LOC Group, has developed an innovative analysis and modelling process to understand why large windfarm monopiles oscillate in smaller wave heights.
This important research identified that migrating raptor species tend to be attracted to offshore wind turbines and that the risk of colliding with wind turbines at sea is much greater than previously assumed. The abstract and resulting discussion of the paper are provided below. The full paper can be downloaded by clinking the links on this page.
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.
Germany plans to cap the expansion of offshore wind power at the start of the next decade to ensure the future growth of renewables keeps step with the construction of new power lines.
