Renewable energy is essential to modern society – reducing harmful emissions from fossil fuels and making us more self sufficient. This site will explore what people are doing to help get us closer to a greener, renewable energy sourced world Read more »
The higher winds out at sea potentially make offshore wind energy capture a huge contributor to our energy needs. Offshore wind turbine technology has developed at a fast pace over the last few years with some of the world’s biggest utility companies heavily involved in offshore wind energy projects. Some significant barriers however are present with the technology – the most problematic being the harsh environment out at sea. Construction and maintenance of offshore wind turbines is more expensive than for their onshore cousins with in many cases specialist vessels required.
This category contains information and news on offshore wind turbine technology from new floating turbine foundations to who is leading the world in terms of development.
A specialised vessel is now installing wind turbine monopiles and transition pieces at Sheringham Shoal offshore wind farm off the UK north Norfolk coast.
The 317 megawatt (MW) wind farm is located between 17 and 22 km north of the town of Sheringham. Construction work began in March of this year and the wind farm is expected to be generating green electricity by the end of 2011.
Read: Wind Turbine Installation Kicked off at Sheringham Shoal118 new offshore wind turbines were connected to the electricity grid network in the first half of 2010 according to The European Wind Energy Association (EWEA) today.
The new offshore wind farms across Europe total 333 Megawatts (MW) indicating that 2010 is set to be a more progressive year than 2009 which delivered 577 MW at the end of the full year. 151 additional wind turbines have been built but not connected to the grid taking the total installed to 440 MW.
According to EWEA figures there are now 43 operational offshore wind farms in Europe with a total capacity of 2,396 MW.

According to industry sources, the company has been looking for a finance partner to share the £2bn offshore wind investment required for well over a year. Wind turbine manufacturer Siemens has also bought a 10% stake in the project.
Read: German Companies Join Forces to Build UK Offshore Wind FarmThe UK Prime Minister Gordon Brown visited the Siemens facility in Manchester this week and took the opportunity to speak of the bright future for the company in the offshore wind sector.
The tour involved visiting the facility that has carried out work on offshore wind energy. There were alse demonstrations of technologies used in the oil and gas sector, power stations and other industries.
Brown praised the work of Siemens in the UK and pointed to its crucial role in the future of UK wind energy and renewables.
Read: Brown Praises Siemens Offshore Wind Energy WorkMinistry of Defence (MOD) objections to over 3 GW of UK offshore wind farms have been resolved further to years of discussion and new funding.
The 5 offshore wind farms off the east coast of England in the Greater Wash were considered to pose a conflict with air defence due to the potential for wind turbines to show up on the MOD’s radar screens. However cash has been stumped up by the Department of Energy and Climate Change, and the wind industry to buy a new TPS77 radar which has the ability to screen out the wind turbines.
Read: Ministry of Defence Withdraws Objection to UK Offshore Wind FarmsMeasures to make investment in offshore wind vessels more attractive are being urged by European Shipyard and Wind Energy Associations.
The Community of European Shipyards Association (CESA) and the European Wind Energy Association (EWEA) want the European Commission and European Investment Bank to help stimulate the funding of new ships to build offshore wind farms.
Read: €2.4m needed for Offshore Wind Farm Ship InvestmentsThe CEO of British Gas owned company Centrica has warned that the delivery of a 3rd round of UK offshore wind farms is “questionable”.
Centrica CEO Sam Laidlaw told Timesonline today that the company has doubts as to whether the proposed 32 Gigawatts of offshore wind farms around UK shores would ever go ahead. Despite benefiting from cross party support, the Round 3 offshore wind energy programme is set to be challenged by spiralling costs.
Laidlaw said,
Read: Centrica CEO Doubts Offshore Wind Farm DeliveryA new wind turbine blade testing factory is set to be constructed near Newcastle according to an announcement by Clipper Windpower this week. The news has been warmly welcolmed after the recent Vestas blade factory closure on the Isle of Wight.
The 4000 m2 factory will be part funded by an offshore wind technology grant of over £4m (over US $6m) from the Department of Energy and Climate Change. It is expected to be constructed by September of this year.
The North East has suffered from the recession acutely but the new wind turbine facility is expected to help the region become an important economic hub for offshore wind energy.
Read: New Wind Turbine Blade Factory for North East EnglandThe European Wind Energy Association has claimed that offshore wind power is vital for Europe’s future in a new report published this month.
The report “The European Offshore Wind Industry – key trends and statistics” confirms that a total of eight new wind farms comprising 199 offshore wind turbines were connected to the grid in 2009. With a combined power generating capacity of 577 megawatts (MW) this represents a growth rate of 54% compared to the 373 MW installed during 2008.
During 2010, the EWEA anticipates the construction of 10 further European offshore wind farms, adding 1,000 MW and equivalent to market growth of 75% compared to 2009.
According to EWEA more than 100 GW of offshore wind farms are currently being planned by project developers and utilities.
Average water depths for offshore wind farms installed during 2009 was 12 metres compared with 21.8 metres for offshore wind farms currently under construction and up to 80 metres for the latest round of offshore areas announced by the UK last week.
Read: Offshore Wind Energy Vital for Europe’s FutureGrid upgrades need to be approved immediately if the wind energy industry is to avoid delays in the build-out of new offshore wind farms according to the British Wind Energy Association.
The announcement of the 3rd round of UK offshore wind farms made by the Crown Estate on Friday could lead to a quarter of the UK’s electricity coming from offshore wind energy. However the 32 Gigawatts of potential capacity will only be built if it can be connected to new UK grid infrastructure.
Secretary of State for Energy and Climate Change Ed Miliband said on Friday “we know that there is still a huge amount of work to do but today marks a very important first step”.
Crown Estate CEO Roger Bright said that the round 3 programme has cross party support – and that this will help in terms of investor confidence. It will however be interesting to see if the Conservative position on offshore wind energy changes if government money is required to contribute towards the new grid infrastructure or if electricity bills need to go up substantially to pay for the works.
Read: Grid Approvals Needed Immediately for 3rd Round of Offshore Wind FarmsThe Crown Estate has today announced the 3rd round of UK offshore wind farms. It comes as no surprise that the big winners are giant consortiums made up of globally operating utilities and companies with offshore experience. The winners will be taking on unprecedented challenges with sites up to 195km offshore and water depths of up to 80 metres.
The largest zones at Doggerbank (9000 Megawatts) and Norfolk (7200 MW) go to consortia giants Forewind and East Anglia Offshore Wind. Forewind is made up of RWE renewables, Scottish and Southern Energy, Statoil and Statkraft. East Anglia Offshore Wind is Scottish Power Renewables and Vattenfall Vindkraft.
Eddie O’Connor’s Mainstream Renewables and Siemans bagged the 4000 MW Hornsea zone, whilst SeaGreen Wind Energy Ltd equally owned by SSE Renewables and Fluor, won the Firth of Forth Zone.
Eon and Dutch utility Eneco were left with the smaller south of England coast sites off Brighton and the Isle of Wight.
Prime Minister, Gordon Brown MP said: “Our policies in support of offshore wind energy have already put us ahead of every other country in the world. This new round of licences provides a substantial new platform for investing in UK industrial capacity. The offshore wind industry is at the heart of the UK economy’s shift to low carbon and could be worth £75 billion and support up to 70,000 jobs by 2020.”
Read: 3rd Round of UK Offshore Wind Farms AnnouncedIt appears that floating wind turbines are set to become a reality in the near future if the signs of a newly emerging supply chain are anything to go by.
The Hywind, a 2.3 megawatt (MW) floating wind turbine made by Siemens, combines technologies from both the wind farm industry and the oil and gas sectors, and was installed in June of this year. It is being tested off the coast of Norway for two years. Since the installation of the turbine new products are starting to emerge which would be dedicated to the technology.
The video below shows a specialist barge which could be used to transport and put into place floating wind turbines. This is but a small indicator of the potentially huge benefits of offshore wind energy when it comes to new business and green collar jobs.
Read: Floating Wind Turbine FutureAfter the PR disaster of the Vestas factory closure on the Isle of Wight, the UK Prime Minister is looking to reel in another wind turbine manufacturer and step up investment to get the country back on the green manufacturing track.
The Guardian’s Terry Macalister reported yesterday that PM Gordon Brown wants Siemens to open a factory in the UK as soon as possible. The move would provide a renewable energy manufacturing base and green collar jobs. The goverment is desperate to secure economic benefits from its huge potential wind energy market.
According to the Guardian, the prime minister will meet CEO of Siemens, Peter Löscher to provide some certainty and comfort on the delivery of a large scale offshore wind energy market. This lack of confidence in wind energy market growth was what led to the Vestas decision to abandon the UK.
A Siemens offshore wind representative said that the company will be closely watching what comes out of the Crown Estate’s Round 3 offshore wind farm license announcements which are imminent.
Read: UK Back on the Green Energy Investment TrackAlthough not officially announced by the Crown Estate, the next round of huge UK offshore wind energy sites have been informally allocated to wind energy developers behind the scenes.
The 10,000 Megawatt Doggerbank area over 50miles east of northern England is rumoured to have been ringfenced for the consortium giant made up of RWE npower, Scottish and Southern Energy, Statkraft and Statoil Hydro known under the umbrella “Forewind”.
Scottish Power and Vattenfall are believed to be favourites for 5000 Megawatts in the wider Wash area, off the Norfolk coast.
Read: Utilities with Financial Muscle win Offshore Wind Energy licensesIt will have taken nearly 10 years to get the first round of UK offshore wind energy projects up and running by the time the last Round 1 offshore wind farm is completed at Rhyl Flats later this year.
Back in April 2001, following a pre-qualification process, 18 companies were selected by the Crown Estate to progress projects in the first round of offshore wind farm sites on the UK seabed. This represented an unprecedented step by the then Department of Trade and Industry (DTI) in pushing forward offshore wind farms. Under the agreements, the companies were given a three-year period in which to secure the required consents for a full lease to be granted by the Crown Estate.
npower renewables built the first commercial scale offshore wind farm in UK waters in 2003 between Rhyl and Prestatyn off the north coast of Wales. This 30 turbine wind farm known as North Hoyle was built with help from capital grants and now generates enough green electricity for the annual average needs of 40,000 homes.
Over 6 years later npower has purchased the rights for the development of sister project “Rhyll Flats” from Celtic Offshore Wind Limited (COWL). The site is located to the west of North Hoyle 5 miles from shore.
Read: Last of the Round 1 Offshore Wind Farms Heads for 2009 CompletionThe UK Government announced its Second Call for offshore wind energy demonstration projects today. The Second Call has, according to the Government a value of £10 million (US $16.4m) ring fenced for the deployment of offshore wind.
The Offshore Wind Demonstration Call is being administered through Solutions for Business, a Government support vehicle for new products. The aim of the funding is to stimulate and encourage the development and demonstration of offshore wind technologies and components for larger multi-megawatt wind turbines.
The UK Government desperately wants the wind farms in UK waters within the 2020 timeframe to meet its climate change commitments. Bids must be received by 28 August 2009. Application forms, guidance notes and the call for proposals are on the Department for Energy and Climate Change (DECC) website.
Read: Second Call for Offshore Wind Demo ProjectsIn order to meet the renewable energy aspirations of the UK government, offshore wind power developers need to find 10,000 km2 of sea area.
A strategic environmental assessment carried out by The Department of Energy and Climate Change (DECC) calculated that up to 10,000 km2 of sea area would be needed to accommodate 25 Gigawatts (GW) of installed offshore wind energy capacity. This area of sea could be difficult to find given the number of ecological constraints – birds and marine life – and the need for shallow waters for economic reasons.
Read: Huge Area of Sea Needed for Offshore Wind TurbinesThe world’s first ‘full scale’ floating wind turbine has been installed off the Norwegian coast by Statoil Hydro.
The 2.3 Megawatt turbine has 100 metres of ballast below the water to support the massive structure. It is expected to generate enough green electricity for the equivalent of 1600 UK homes.
The project costing US $16m is a test case with US $9m allocated for ‘testing’. This video explains the project and interviews a StatoilHydro representative.
Read: World’s First Floating Wind TurbineThe Department of Energy and Climate Change opened its doors yesterday to offshore wind energy research and development companies with bids for a share of a £10 million (US $16m) offshore wind technology fund.
The fund is aimed at stimulating the development of next-generation offshore wind energy technologies to try and achieve large scale delivery around the UK before 2020.
The Government has high hopes for offshore wind, relying heavily on the technology to meet its climate change commitments.
Read: £10 Million Offshore Wind Technology Fund up for GrabsDONG Energy, E.ON and Masdar announced yesterday that they will invest 2.2 billion euros in the 300 turbine + London Array project 12 miles off the Kent and Essex coasts in the UK.
The announcement means that the first phase of the world’s largest offshore wind farm will go ahead. The onshore work for the 1000 megawatt project is due to start in early 2011.
