Nordex largest wind turbine N149 installed at Wennerstorf II wind farm

On 21 August 2018, the first of two N149/4.0-4.5 turbines with a nominal output of 4.5 megawatt was installed at the Wennerstorf II wind farm located roughly 30 kilometres south of Hamburg. Mr Jörg Hempel, who is in charge of German business at Nordex Group said that “We are pleased to have completed this beacon project in time for the commencement of WindEnergy Hamburg 2018. In addition to our turbines at the port of Hamburg, the N149/4.0-4.5 in the vicinity of the Nordex main office in Hamburg is another impressive project with which we can demonstrate the Nordex Group’s state-of-the-art technology to our customers.”

The turbines in Wennerstorf II are just the beginning. Karsten Brüggemann, Head of Global Sales at Nordex Group said that "We have received very favourable feedback from our customers. Many customers in Europe and other parts of the world have already included the turbines in the necessary approval procedures”.

Originally, the Wennerstorf wind farm consisted of four turbines, each with a nominal output of 1.3 megawatts, which had been producing electricity since 2003. In 2015 the developer ABO Wind decided to repower this site with the latest technology by replacing the old turbines with new ones. In doing so, it opted for the first turbine from the Delta4000 product series, the N149/4.0-4.5: With a total installed output of 9 megawatts, the capacity of the Wennerstorf II wind farm will increase by 73 percent.

New turbines must undergo extensive independent testing to obtain all relevant certificates. The site meets the requirements of IEC 61400 and offers wind conditions of approx. 6.5 meters per second on average. Consequently, it offers a good possibility to carry out the planned measurements of power performance, sound and electrical characteristics as well as the validation of the mechanical loads in the power mode with the maximum output of 4.5 megawatts.

The turbines are going to be equipped with radar-controlled aviation obstruction lighting due to their total construction height of 200 meters. The obstruction lights are only activated when an aircraft flying at an altitude of below 600 metres approaches the turbines within a radius of four kilometres. This avoids the need for continuous obstruction lighting during the night.

The N149 turbines are also well designed in terms of acoustics for increasing citizen acceptance, with a sound emission level of less than 106.1 dB(A) even when operating at full load. In addition, they can be operated in a variety of sound-optimized modes which can be set according to wind direction and the time of day to keep noise levels as low as possible.

Smart logistics solution for the transportation of the almost 73 meter rotor blades

Produced by Nordex itself, the single-piece rotor blade of the N149/4.0-4.5 measures almost 73 meters in length. The rotor diameter of 149 meters contributes significantly to the very low cost of energy and the high turbine yield. As with the predecessor models, the rotor blades of the N149 are made of carbon and glass fibre.

Vestas intends to cease production in Spain

To sustain its competitiveness in the growing global market for wind energy, Vestas continuously introduces new products and optimises its global footprint to meet market demand across regions. By doing so, Vestas aims to ensure a competitive product portfolio, economies of scale and continuous optimisation of manufacturing, transportation, and sourcing costs. Recent market developments have seen a decreasing demand for the 2 MW wind turbine platform in Europe, while the demand for the 4 MW platform in the region can be met by less capacity than currently provided by nacelles factories in Europe and other regions where Vestas recently has established production capacity.

Responding to these market developments and to sustain its competitiveness, Vestas intends to cease production at its assembly factory in León, Spain, affecting all of the factory’s 362 employees. The employees have been informed about the intention to cease production through the local works council and will also receive a letter from Vestas with information on the situation and contact details for further information.

As per Spanish law, Vestas will now initiate negotiations with local works councils for all affected employees. Vestas is exploring opportunities to relocate employees from León to other Vestas manufacturing and service sites in Spain, as well as opportunities outside of Vestas through an outplacement plan. The negotiations are expected to be finalised within 30 days from commencement, as prescribed by Spanish law.

Spain remains a key market to Vestas with more than 4 GW of installed turbines, 6 GW under service and around 2,000 employees as of 30 June 2018. Vestas continues to have a strong local footprint to serve Spanish and international markets, including a generator factory in Viviero and a blades factory in Daimiel where Vestas is investing to set up production of blades for the V150-4.2 MW turbine. Additionally, Vestas also has Service hubs and warehouses, its Mediterranean headquarters in Madrid and a strong local supply chain in Spain.

The financial cost of ceasing production at the assembly factory in Leon will mainly relate to write down of land and buildings. These costs will be booked as special items and will be included in third quarter of 2018.

Wind farm being considered at Snorre and Gullfaks

Equinor and partners at Gullfaks and Snorre have decided to explore the possibilities of supplying the Gullfaks and Snorre fields with power from floating offshore wind. This could be the first time an offshore wind farm is directly connected to oil and gas platforms. The project forecasts a reduction of CO2 emissions by more than 200,000 tonnes per year, equivalent to the emissions from 100,000 cars.

Equinor has performed an extensive study evaluating which oil and gas installations on the NCS are suited for power supply from a floating offshore wind farm. The Snorre and Gullfaks fields in the Tampen area in the northern North Sea are the best match for realising this idea.

Equinor’s executive vice president for New Energy Solutions, Pål Eitrheim said that “Reducing the use of gas turbines by supplying platforms with power from floating offshore wind is a challenging and innovative project. It may also facilitate new industrial opportunities for Norway, Equinor and Norwegian supply industry within profitable renewable energy, while enabling oil and gas production with low CO2 emissions. The Hywind Tampen project is contributing to further developing floating offshore wind technology, reducing costs and making the solutions more competitive.”

The solution to be further explored is a wind farm consisting of 11 wind turbines based on Equinor’s floating offshore wind concept, Hywind. The 8 MW turbines will have a combined capacity of 88 MW, and are estimated to meet about 35% of the annual power demand of the five Snorre A and B, and Gullfaks A, B and C platforms. In periods of higher wind speed this percentage will be significantly higher.

Equinor’s executive vice president for Development and Production Norway, Arne Sigve Nylund said that “I am pleased that the partnership has managed to mature this from an idea to a concept choice. In order to maintain profitable operations on the NCS in the long term, it is essential that we do our utmost to further reduce the carbon footprint from our activities. The Tampen project will make a considerable contribution to the industry’s ambition to reduce CO2 emissions on the Norwegian continental shelf by 2.5 million tonnes per year from 2020 to 2030.”

Equinor explores floating wind turbines to power North Sea oilfields

Reuters reported that Norway's Equinor is considering whether to build an offshore wind farm with floating turbines to provide electricity for its Gullfaks and Snorre oilfields in the North Sea. If materialised, it would be the world's first floating offshore wind farm powering oil platforms and is estimated to cost around 5 billion Norwegian crowns (USD 591.5 million) and could reduce emissions of carbon dioxide by more than 200,000 tonnes per year.

Executive Vice President Arne Sigve Nylund said in a statement that "To maintain profitable operations (offshore Norway) in the long term, it is essential that we do our utmost to further reduce the carbon footprint from our activities.”

Formerly known as Statoil, Equinor earlier this year changed its name to underscore a push into renewable energy under Chief Executive Eldar Saetre, although oil and gas will remain the company's dominant business for decades to come.

The company's first floating offshore wind farm started off Scotland last year, supplying electricity to the onshore market, and Equinor has also announced plans for bottom-fixed offshore wind projects in the United States, Poland and Britain.

It said that a final investment decision on the plan for Snorre and Gullfaks, known as the Hywind Tampen floating wind farm, will be made in 2019, although the aim is first to bring down the cost of development.

Arkona feeds first power into the grid

EON and Equinor's Arkona offshore wind project in the German Baltic Sea continues to strive for completion in record time. Now the energy company E.ON is reporting further progress: the wind farm has fed the first green electricity into the German Electrical grid. Arkona is thus right on schedule. EON, the company responsible for construction and operation, cites the detailed planning and professionally implemented construction process as the reasons for the success. Collaterally with close cooperation 50 Hertz the transmission system operator was able to make it achievable for a partial feed-in option into the German high voltage electrical grid with their precise coordination, before the completion of all grid connections. Now that the first of the 60 turbines is online, further wind turbines are being commissioned step by step.

Mr Sven Utermöhlen, COO of E.ON Climate & Renewables said that “It only took one year from the first monopile installation to the first electricity feed-in. Rarely before has a project been built so straightforward. This is a great achievement on the part of our team and all our project partners and at the same time an important step towards further optimization of offshore wind projects.”

Pål Coldevin, head of New Energy Development at Equinor and Chairman of Arkona's Steering Committee said that “The first electricity from the Arkona wind project is a milestone in the renewable energy market. We are proud to contribute to this with E.ON and the 50Hertz transmission system operator. Arkona is Equinor's fourth wind farm in Europe and an important contribution to Equinor's strategy of evolving from a focused oil and gas company to a broad energy group.”

Together with the first electricity feed-in, the Arkona electrical offshore substation was also energized. E.ON/Equinor and 50Hertz jointly operator the platform. The optimal timing and technical coordination of the companies is helping to optimize offshore grid connection costs and to promptly advance the energy turnaround.

Mr Frank Golletz, CTO of 50Hertz said that “The concept of fast and cost-effective offshore grid connections in the Baltic Sea has also proven its worth in this project. Together with the Arkona wind farm, we have succeeded in planning and constructing an efficient, cost-effective, flexible and safe transformer platform. This is another important step for the development of offshore wind energy in the Baltic Sea.”

With the punctual commissioning of the wind turbines, the importance of the service building in the port of Mukran in Sassnitz on the island of Rügen will also increase. The operation of the wind farm is controlled from there. All 50 newly created jobs have been now be filled.

ABB wins USD 20 million order from MHI Vestas Offshore

ABB has won an order of more than USD 20 million from MHI Vestas Offshore Wind to supply reliable, energy-efficient and compact WindSTAR transformers, which are designed for installation in wind turbines. Borssele III and IV comprise the second phase of the Borssele wind farm. This phase constitutes a 731 megawatt (MW) wind project in the North Sea, 22 kilometers off the coast of The Netherlands and will be capable of providing enough clean energy to power more than 800,000 households. ABB will supply its innovative WindSTAR power transformer, which is specifically designed to fit into the tower of a wind turbine. This transformer enables a new generation of powerful offshore wind turbines to operate at the world’s highest voltage of 66 kilovolts which significantly reduces losses and increases efficiency. It also brings lifecycle benefits and cost optimization.

Mr Markus Heimbach, Managing Director of ABB’s Transformer business unit, a part of the company’s Power Grids division said that “These innovative transformers facilitate the integration of offshore wind energy bringing clean power to consumers and reinforcing our position as a partner of choice for enabling a stronger, smarter and greener grid. ABB is a leader in the wind industry, providing components to turbine manufacturers and enabling the connection of wind farms to the grid.”

As turbine size increases for offshore (reaching 9.5 MW in this project, a world record power level for commercial offshore wind), transformers must remain compact and lightweight with a minimal footprint, while also meeting specific application needs, mechanical structural constraints and costs.

Nabrawind installs world’s tallest steel wind turbine tower

Nabrawind Technologies has completed the installation of the world’s tallest onshore steel wind turbine tower in Eslava, Northern Spain. Standing at 160m tall, the Nabralift full-scale prototype was installed in under two weeks. The tower’s unique design means it can be installed, together with the turbine nacelle and rotor, via a patented self-erecting system using hydraulic jacks, enabling elevation by adding small frame modules at ground level, eliminating the need for massive cranes. The tower is a 20% lighter than the current steel towers and can be transported in standard trucks. The design of the tower also reduces the foundation size, and the installation process can be executed in small assembly platform, reducing the footprint as well as reducing the civil works cost.

The new generation of onshore 3MW-5MW turbines will require very tall towers to accommodate large blades and reach competitive wind speeds in the mainstream low-wind sites . This larger rotor diameter means that the turbine can generate more electricity, more efficiently resulting in less turbines needed to reach desired generation capacity. However, current tall tower technologies face design, logistic and installation challenges that are restraining the growth of this type of products.

Ion Arocena, Nabralift Programme Manager at Nabrawind Technologies, says:“The validation of our technology by means of this prototype marks an important milestone in our commercialisation. We’re confirming 15 to 20 per cent cost reduction versus conventional approaches like tubular steel or hybrid tower, and by next year we aim to produce and install up to 7 towers between 135 and 200 m height.”

The prototype will be tested after installation to demonstrate 25 years of operating life through fatigue load tests. Once complete, Nabrawind Technologies is set to install up to seven more towers in 2019, ranging up to 200m in height.

Wind turbines a potential health risk - WHO

According to new guidelines for Europe that the World Health Organisation has published that Wind power generators can cause health problems if they result in people being exposed to excessive noise levels. Exposure to wind turbines should not exceed 45 decibels during daytime, the Geneva-based UN agency wrote in the guidelines that it developed on behalf of the European Union. In comparison, soft radio music has 50 decibels.

Although the recommendations were drawn up for Europe, they are relevant for the rest of the world because they are based on data from various continents, the WHO said.

European policymakers should heed the guidance, WHO Europe chief Ms Zsuzsanna Jakab said in a statement that "More than a nuisance, excessive noise is a health risk - contributing to cardiovascular diseases, for example.”

German authorities currently recommend a maximum wind turbine noise exposure of 55 decibels during the day.

New wind farms could thrive in Norway without subsidies - State grid

Reuters reported that declining costs and rising power prices mean major new wind farms could be built in the south of Norway without subsidies. The report by Statnett is part of an analysis that Norway's energy regulator NVE is putting together on the potential for increasing the country's wind power generation, which currently has a total estimated capacity of about 1.3 gigawatt.

Statnett said that "The development of increased European and Nordic power prices combined with continued declining operating and development costs has made it profitable to build wind power without subsidies in Norway.”

The analysis said a large amount of wind power could be generated in southern Norway without creating new bottlenecks in the main grid.

However, Statnett added that: "without significantly higher consumer growth and possibly more network capacity, northern Norway and the northern parts of central Norway appear less favourable for further wind power development."

Statnett did not give a figure for the amount of new wind capacity that could be built.
