Ørsted says offshore UK windfarms need urgent repairs

The Danish wind power firm Ørsted has warned that up to 10 of its giant offshore windfarms around the UK and Europe will need urgent repairs because their subsea cables have been eroded by rocks on the seabed. ...Ørsted has found that the rocks placed at the base of the wind turbine foundations to prevent the erosion of the seabed were responsible for wearing down the cable protection system which, in a worst case scenario, could cause the cables to fail.

Ørsted points to possible reason for EUR 403 million cable problem

Leading offshore wind developer Ørsted has suggested that a scour protection method which left the inter-array cables unstabilised could be the potential reason for an up to DKK 3 billion (EUR 403 million) issue across up to ten wind farms in Europe. As reported earlier, Ørsted first became aware of the problem earlier this year during an inspection after an outage at the Race Bank wind farm offshore the UK.

Cable failures hit offshore wind farms

The company identified a total of 10 projects in the U.K. and Europe that used the same design that may need to be remedied. Some projects will be easy to fix. The company can just dump more rocks on top of the cables to make them stay in place. ...But in other cases, Orsted will have to repair or replace the cables. That’s the pricey option that will make up the bulk of the cost, Wiinholt said.

Damaged offshore wind cables to cost Orsted almost half a billion dollars: CFO

“To a large extent we will be able to mitigate it through stabilising the cable protection system. It will be done by dumping rocks on top of the rocks that are already there.” At other wind farms, the cables are so damaged that the company will either need to repair or replace them, which is more expensive than dumping more rocks on top of the existing protection layer.

Germany will not receive electricity on the cable to Norway

The Nordlink cable between Norway and Germany is scheduled to be put into trial operation in December, while testing of IT and trading solutions will start as early as September. Both Statnett and the government are therefore working to reach a solution with the German energy authorities. But why will Germany not use a cable that they themselves have helped to build? They want to use the opposite route and export power to Norway when they have negative prices.

Western Link HVDC outage caused record constraint management payments as wind power surged

The £1.3 billion Western Link was originally due to come online in 2015, but only began operating at full capacity in December 2019. The high cost of balancing the grid given the surge in wind power and the outage comes after The Times reported that in the first six months of 2020, £55.7 million was paid out in constraint payments, while in the whole of 2019 £130 million of constraint payments were made.

Environmentalist challenges construction of grid connection to wind farm

Mr Sweetman is seeking an order quashing a decision of An Bord Pleanala in December 2018 that the construction of the connections servicing a windfarm development located at Ballycumber, Tinahealy, Co Wicklow was exempted development. The central issue concerns his the claim that the works undertaken for the purpose of connecting the Ballycumber Wind Farm to the national electricity grid should have been subject to an environmental impact assessment.

MP cancels parliamentary debate on Norfolk wind farms, so he can speak at Norwich hearing into issue

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.

Connection delays may scupper 16 wind energy projects

A total of 16 wind energy projects – with full planning permission and grid connection offers – “are at medium or high risk of not being built” ...The problem is arising because connection dates project developers have been offered are all for late 2019, according to IWEA chief executive Dr David Connolly. To qualify for renewable energy feed-in tariff (REFIT) schemes, they need to be built, connected and exporting electricity by March 31st, 2020.

Wind farm firm scraps plan for relay stations in Norfolk countryside

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.

‘Game over’ for pylons -as National Grid cancel surveys

Campaigners say that National Grid’s controversial 33-mile proposed pylon route between Cefn Coch and Oswestry costing an estimated £300 million is now under threat after Energy Minister Andrea Leadsom confirmed that windfarms at Llanbadarn Fynydd, Llaithddu, Llanbrynmair and Carnedd Wen were being refused.

Power line standoff holds back Germany's green energy drive

The resistance is developing into a major headache for Merkel. It is dividing her coalition, undermining her most ambitious domestic policy, creating uncertainty for some of Germany's biggest companies, and threatening the goal of producing nearly half of all power from renewable sources by 2025 while remaining Europe's economic powerhouse.
