A billion-pound wind farm has been closed for more than two weeks after a technical fault brought it to a standstill. Rampion Wind Farm, which is 13km off the Sussex coast, is still out of commission after an electrical problem on October 26.
People are just looking at the map and saying, ‘oh my god, this is where I fish,’ so there’s a sense of panic. “We only heard about this when the applications were lodged,” Ms McIntyre said. “You must understand how huge this was: it was a complete and utter shock. It’s only in the last few weeks that people are realising how big these are going to be. The biggest wind turbines in the world.”
The energy minister is to launch a review into the impact wind farms have onshore amid claims the countryside is being “concreted over” with substations and cable corridors built as supporting infrastructure. The move has been welcomed by campaigners who have been fighting proposals in the East of England to build substations and cable trenches “the size of Wembley stadium” to get electricity from wind farms to the National Grid.
The number of porpoises washed ashore has increased enormously in recent decades. Where fewer than a hundred dead porpoises were reported each year in the 20th century, this number increased steadily. Peak stranding years were 2011 and 2013 when almost 900 stranded dead porpoises were found every year on the Dutch coast alone!
While Taggen Vindpark AB obtained a permit for the project from Sweden’s Land and Environmental Court back in 2012, the partners applied to change the original 83-turbine application to include higher and more powerful machines ...The Armed Forces, however, did not greenlight the change and also denied the project as a whole,
A decision on whether the world's largest offshore wind farm will be built has been delayed amid fears it will harm endangered birds. The Government was meant to rule on October 2 whether or not the Hornsea Three wind farm - 120 kilometres off the north Norfolk coast - would get the go-ahead.
"We'll be absolutely there on the front line to attack it, because we believe what we've got now is more than we should have to bear... We've got the Snowdonia National Park and looking out from that you'll see this forest of metal turbines. It's just diabolical," he said. "Scenery is all part of what we sell as a tourist destination and tourism is our only industry. To put those there is industrialising the seascape.
RSPB Scotland director Stuart Housden stressed that the wind farm projects threatened to kill thousands of Scotland’ s internationally protected sea birds every year, including thousands of puffins, gannets and kittiwakes. “While we fully support deployment of renewable energy, this must not be at any cost,” he said.
Data collected will include three-dimensional radar tracks as well as video footage of birds moving through the development. It will allow identification of specific species, showing flight height as well as individual and group behaviour. The findings will reveal whether and how often birds might be colliding with the giant structures or if they are being displaced from important feeding grounds.
The blackout may have been caused by the unexpected shutdowns of the Hornsea offshore wind farm, which is owned by the Danish wind farm company Orsted, and the Little Barford gas-fired power plant, owned by German utility giant RWE. National Grid data showed both of the generators dropped from the grid at around the same time. ...“We would have expected the system to cope with this size of loss of generation,” an Enappsys spokesman said. “This implies that there may have been [other] issues at the time of the trips.”
Electricity bills could double to bail out new wind farms that have massively underestimated their operating costs, a former adviser to the World Bank has claimed. Two offshore wind projects secured contracts to supply renewable energy at reduced costs in 2017 and it was hailed the result of huge strides made in technology and engineering, sparking hopes of a green jobs boom.
Skilled workers are relying on food banks to survive as the contract for a £2 billion wind farm off the coast of Scotland looks set to go overseas.
An attempt to improve wildlife diversity at a wind farm in the North Sea has failed as 85% of oysters introduced there have died, reports the Volkskrant.
The company said it has reached agreement with Trianel Windkraftwerk Borkum II GmbH & Co KG (TWB II) for a revised contract that will ensure delivery of turbines for the German offshore wind project. The remaining 17 of 32 wind turbines for the project are due to be delivered in Q3 2019.
This paper examines the risks and liabilities of decommissioning offshore wind energy facillties and the lack of regulatory oversight needed to ensure proper planning for taking the turbines down and restoring the site to its orginal state.
“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.
Development of offshore wind energy over the next decade would enable Ireland embrace an electric future and decarbonise its heat, transport and industry, according to SSE Ireland managing director Stephen Wheeler.
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.
Every time a drop of rain hits a wind turbine blade it contributes to a process that ends in small cracks being formed in the leading edge of the blade that eventually ruin the coating on the blade. The bigger the drop, the worse the damage, reports DR Nyheder.
