The Nordex Group is extending its product portfolio with a multi-megawatt machine in the 5 MW class. After the N149/4.0-4.5 and the N133/4.8, the new N149/5.X is the third wind turbine type in the Delta4000 series. The N149/5.X is designed for moderate and light-wind areas and can also perform optimally at sites with complex requirements. Apart from the classic core markets in Europe, the target markets for the N149/5.X also cover global growth regions such as South Africa, Australia and South America.

The N149/5.X is designed for maximum flexibility and can be operated in different modes in the 5 MW range depending on site requirements and customer needs. This enables customers to individually configure the wind farm in terms of the output, capacity and lifetime of the turbine, as well as with regard to sound requirements, and thus adapt it ideally to the company’s respective business model. The N149/5.X is a logical progression based on the successful approach of a flexible power range in the N149/4.0-4.5.

Thanks to the proven technological basis of the Delta4000 product series we are in a position to continuously develop highly efficient solutions for different wind regimes and different geographical regions and to ensure short lead times for product launches. We have designed the N149/5.X with its maximum flexibility and efficiency to exactly meet the needs of our customers,” says José Luis Blanco, CEO Nordex Group.

A new and highly efficient gearbox is used and the electrical system of the Delta4000 series scaled up in order to achieve the high power output in the 5 MW range. The efficient electrical system with its double-fed asynchronous generator, which has proved itself in the field for more than two decades, and the partial converter have been retained. The N149/5.X also uses the N149/4.0-4.5 rotor blade, which further increases the modularity of the Delta4000 product series. The exterior dimensions of the nacelle remain unchanged so that proven logistical and installation processes can be used as in the past.

The wind turbine is offered with a wide range of sound power modes in order ensure than even the most demanding noise requirements can be met. For instance, the turbine can be operated with a low sound power level of 104.8dB(A) while still achieving a power output of 5.5 MW. The machine can also be run in higher power modes at sites where sound emission levels are not critical.

Different tower options are offered for the N149/5.X – up to a height of 164 metres, depending on the market. The wind turbine options also include a cold-climate version for operation at temperatures down to -30 °C as well as an anti-icing system for rotor blades.

The wind turbine is due to go into series production as of 2021.

At WindEurope Conference & Exhibition from 2 – 4 April 2019 in Bilbao, Spain, visitors will have the opportunity to obtain detailed information on the N149/5.X.

GE Renewable Energy has announced that the prototype for its Cypress platform, the largest onshore wind turbine for GE in the field, has been successfully installed and is fully operational, producing power at a rated level of 5.3 MW in Wieringermeer, The Netherlands. Company officials hail the milestone as a key step in commercializing a unit able to both lower the cost of electricity and offer additional flexibility in terms of where wind turbines can be located.

The first turbine in the platform, the 4.8-158 turbine was introduced in September, 2017. The 5.3 MW turbine and Cypress Platform name were introduced in September, 2018.

The Cypress 5.3 MW prototype was installed in late 2018 and produced its first kilowatt in February 2019. GE Renewable Energy will continue to operate the prototype during the months to come in order to validate the performance of the Cypress platform. This testing will also support the process of obtaining the Type Certificate, a key step in commercializing the product.

The platform is offered with multiple ratings and varying hub heights. It will enable a lower cost of electricity by matching each wind turbine solution to specific site needs, which is critical as wind power increasingly competes on price with other sources of power generation.

The Cypress platform will be powered by a revolutionary two-piece blade design that makes it possible to use larger rotors and site the turbines in a wider variety of locations. The AEP improvements from the longer rotors help to drive down Levelized Cost of Electricity (LCOE), and the proprietary blade design allows these larger turbines to be installed in locations that were previously inaccessible.

Vestas has been at the frontier of wind energy for 40 years, introducing market-leading wind energy solutions that have driven the down cost of energy and taken wind energy from niche to mainstream. Today, Vestas introduces the EnVentus wind turbine platform, which represents another significant step forward in the continuous efforts to lower the levelised cost of energy and accelerate the global transition to a more sustainable energy mix.

The EnVentus platform will initially be available in two new variants: the V150-5.6 MW and V162-5.6 MW, together covering low, medium and high wind conditions. Based on advanced modular design, EnVentus supports Vestas’ vision to become the global leader in sustainable energy solutions and provides a wider range of turbine configurations that can better meet evolving customer needs.

EnVentus represents the next generation of wind turbine technology and connects four decades of wind energy innovation with the experience and knowledge represented by Vestas’ 100 GW of installed wind turbine capacity. The new platform demonstrates the benefits of Vestas’ industry-leading investments in R&D and unmatched volume of wind data.

Anders Runevad, Vestas President and CEO, says “EnVentus is a great achievement by everyone at Vestas that allows us to meet customers’ increasing needs for customisation and continuous reduction of the cost of energy. Our relentless focus on delivering industry-leading revenue and profitability the past years has given us the resources to develop a new platform built on our world-class R&D. Following our 2018 order record and 100 GW milestone, EnVentus is another important step in Vestas’ journey to become the global leader in sustainable energy solutions”.

As Vestas’ first platform introduction since 2011, EnVentus combines proven technology and system designs from Vestas’ 2 MW, 4 MW and 9 MW platforms with advanced modularity, building a foundation that reliably and efficiently lowers the cost of energy. The journey towards a modular platform was initiated in 2012 and is expected to create increased scale advantages and opportunities to optimise current and future value chain needs, such as design cycles and transportation.

Anders Vedel, Vestas Chief Technology Officer, says “Vestas has pioneered wind energy since 1979 and by introducing EnVentus and its first two variants, we connect heritage with innovation to underline our technology leadership. With the introduction of a platform built on advanced modularity, we increase our ability to provide customised solutions while ensuring value chain optimisation. I’m incredibly proud of everyone in Vestas who has been part of developing our new platform and variants, once again showing Vestas has the most passionate and innovative minds in the industry”.

The platform’s first two variants: the V162-5.6 MW and V150-5.6 MW will be globally applicable and are added to the wide range of Vestas’ existing 2 MW and 4 MW platform turbines, giving customers an unmatched combination of turbines to harness wind in any specific location. The turbines feature a full-scale converter, capable of meeting complex and differing grid requirements in local markets. The full-scale converter is matched by a permanent magnet generator for maximum system efficiency and balanced by a medium-speed drivetrain.

With a swept area of over 20,000 m2, the V162-5.6 MW offers the largest rotor size in onshore wind to achieve industry-leading energy production. When paired with a high capacity factor, the V162-5.6 MW offers 26 percent higher annual energy production than the V150-4.2 MW, depending on site-specific conditions. It is primarily relevant in low to medium wind conditions, but also has extensive applicability in high average wind speeds depending on site-specific conditions. The first V162-5.6 MW prototype is expected to be installed in mid-2020, with serial production later that year.

The V150-5.6 MW takes our existing 150m rotor and applies it to higher wind speeds and extended market applicability. When combined with its higher generator rating, the tubine increases the annual energy production potential by 30 percent compared to V136-4.2 MW depending on site specific conditions. It is primarily relevant in medium to high wind conditions. The first V150-5.6 MW prototype is expected to be installed in the second half of 2019, while serial production is scheduled for mid-2020.

Initially, the new variants are targeted at the onshore market, but may have offshore applicability.

The name EnVentus combines “energy”, “environment”, “invent” and the latin word for wind “ventus” to encompass our pioneering and innovative heritage within wind energy and aspiration to lead the global transition to a more sustainable energy system.

Vestas has been a pioneer in wind energy solutions and a cornerstone in making the world’s energy mix sustainable. In late 2018, a new milestone was reached in that 40-year journey, as Vestas achieved 100 GW of installed wind turbines with the installation of a V110-2.0 MW wind turbine at MidAmerican Energy’s Wind XI project in Iowa, U.S. Since the inaugural installation of a V10-30 kW wind turbine in Denmark in 1979, Vestas has installed over 66,000 wind turbines in around 80 countries across six continents and been a key part of taking wind energy from niche to mainstream.

Today, Vestas’ largest onshore wind turbine is the V150-4.2 MW turbine, and the 100 GW milestone has thus been made possible by the continuous evolution of our wind energy technology and solutions, which have seen output and efficiency increase to a level that has made wind energy the cheapest form of electricity in many markets.

We have pioneered wind energy across the globe for 40 years, and to install 100 GW together with our customers and partners is something we are extremely proud of as it underlines how far Vestas and wind energy have come. It’s also a pleasure to celebrate this milestone with a key customer like MidAmerican Energy”, says Anders Runevad, Vestas President and CEO. “Reaching this milestone has required continuous innovation, strong commitment and great execution from all Vestas’ employees, and the 100 GW therefore represents a key part of the foundation that enables us to develop the sustainable energy solutions of the future”.

During the journey to 100 GW, Vestas has helped remove over a hundred million tonnes of CO2 from the atmosphere by providing sustainable and cost-effective solutions to meet the world’s energy demand. By crossing this 100 GW threshold, Vestas has installed approximately 10 percent of the world’s total 1 TW of installed wind and solar energy capacity1.

The capacity of the Wind XI project will grow to up to 2,000 MW and consist of multiple sites in Iowa placed into service between 2017 and 2019. Powered by V110-2.0 MW turbines built at Vestas’ factories in Colorado, Wind XI will deliver clean, low-cost wind energy to MidAmerican Energy’s customers and communities. Vestas will provide operations and maintenance for Wind XI project sites via long-term AOM 5000 service agreements.

Based on global average electricity, 100 GW of wind energy saves around 129 million tonnes of CO2 annually2, equalling CO2 emissions from3:

  • 141 billion pounds of burned coal
  • 298 million barrels of oil
  • 22.54 million U.S. homes yearly electricity use
  • 33 coal-fired power plants
  • Carbon sequestered from 152 million acres of forest

Acciona Energía has started construction work on its second wind farm in Texas —the company’s ninth in the U.S. — which will increase ACCIONA’s U.S. wind power capacity to 866 megawatts (MW). An investment of around €176 million ($200 million at the current exchange rate), Palmas Altas will have a capacity of 144.9 MW and be equipped with 46 wind turbines of Nordex technology. Grid connection is planned for November 2019.

Located in Cameron County, near the San Roman wind farm that Acciona started up in December 2016, the new facility will produce around 524 gigawatt-hours (GWh) of clean energy per year, equivalent to the consumption of 43,000 U.S. households. It will offset the emission of 503,000 metric tons of CO2 – the equivalent of taking more 100,000 cars and trucks off the road.

“We are proud to be furthering our investment in the United States, one of our main strategic markets where we remain alert to any opportunity offered by this promising sector” said Rafael Esteban, CEO of Acciona Energy USA Global LLC.

The Palmas Altas project will employ approximately 170 people at the peak of construction. When complete, a 10-person operations team will staff the wind farm. Over its 25-year lifespan.

Nordex wind turbines

The wind turbines installed in Palmas Altas will be Nordex’s AW125/3150 model with a rotor diameter of 125 meters, mounted on an 87.5-meter steel tower (hub height). The energy produced by the wind farm will be sold in the ERCOT-South Texas wholesale market.

Acciona currently owns and operates eight wind farms in the United States. In addition to San Roman (93 MW), mentioned above, the company has three others in Oklahoma (329 MW), two in the Dakotas (192 MW), one in Illinois (101 MW), and one in Iowa (6 MW). It also has a 64 MW CSP plant in the Nevada Desert.

In addition to Palmas Altas, Acciona Energía has other wind power projects in its pipeline that will increase its operational capacity in the United States.

In recent years, increasing pressure to drive down wind turbine manufacturing prices has spurred enormous advances in technology. For example, turbine and rotor sizes have grown at an impressive speed, and many other innovations have enabled significant improvements in terms of energy output and cost efficiency. The introduction of auction systems for tendering onshore and offshore projects in a growing number of countries around the world has contributed to intensifying international competition, resulting in substantial (project) lifecycle-based price drops and huge value-chain cost reduction pressure.

At the Global Wind Summit in Hamburg, the industry will demonstrate and discuss what can be achieved by current and emerging technologies. From 25 to 28 September WindEnergy Hamburg, the world’s leading expo for the onshore and offshore wind industry will open its gates, featuring 1,400 exhibitors from around the world. In parallel, WindEurope will hold its global conference at the Hamburg Messe site.

A crucial factor enabling cost reductions is the growing trend towards industrial-scale series production. As a consequence, existing supply chains are used more extensively, product development costs drop, and the technology and overall risk profile becomes more favourable. The ongoing cost reduction pressure affects hardware suppliers, project developers, financial and legal consultants, and other parties, forcing them to find the most cost-effective solutions to present in auctions and project tenders.

In several key renewable energy markets, including Germany and India, onshore wind and solar increasingly compete for the lowest prices in auction system tendering rounds. For example, the winning prices in India’s first federal (onshore) auction, which totalled 2 GW, were as low as US$ 0.038/kWh. By comparison, solar tariff bids in India fell to a level of just INR 2.97/kWh this year. The Dutch auction system successfully concluded its first non-subsidised offshore wind tender for the 700-750 MW Hollandse Kust I & II project earlier this year. The tender winner, the Swedish utility and WindEnergy Hamburg exhibitor Vattenfall, will build the wind farm with ‘non-decided’ 6-12 MW turbines, and the project should be completed by 2022. Leading offshore turbine and main component suppliers in Hamburg will inform visitors on features and benefits of current product offerings and their competitive advantages in auction scenarios.

Market-specific products

An increasingly common wind industry strategy are modular platforms with flexible ratings, plus multiple rotor sizes and various available hub heights (onshore) to optimally match specific market and geographical conditions. Mean wind speed is a key product driver and a main variable for right configurations in achieving maximum cost effectiveness performance. GE Renewable Energy for example offers a 2 MW platform with flexible ratings between 2 – 2.7 MW and 116-m rotor size, and in 2.2 – 2.5 MW plus 127 m. They and other suppliers will explain visitors on the features and benefits of turbine platforms with high configuration flexibility.

Local production facilities

Localisation of production is another key topic on the agenda of the wind industry, and increasingly a binding requirement in many (emerging) wind markets. India is a typical low-wind market and the second largest in Asia. The WindEnergy Hamburg exhibitors GE, Nordex Acciona, Senvion, Siemens Gamesa, Vestas all manufacture their 2 MW+ low and medium-wind models in-country, which has a favourable impact on turbine CAPEX and thus on the overall project cost-effectiveness. The typical specific power ratings of these products in the 175 – 205 W/m2 range aim at boosting annual yield, thereby contributing to higher asset long-term cost-effectiveness. The Nordex Acciona 3 MW AW3000 series is the most powerful turbine produced in the country, with the latest current flagship model for auctions, the AW140/3000 featuring a 140-metre rotor diameter (195 W/m2). Enercon announced its re-entry into the Indian market with a 3.5 MW EP3 model boasting a 138-metre rotor diameter. The first turbines are expected to be erected in early 2020.

Components custom-tailored to the specific requirements of local markets are another key to unlock additional saving potential. For example, the Argentinian government intends to install 6-7 GW of onshore wind power by 2025. This means that the country is poised to become Latin America’s second largest wind market in the coming years. As in other Latin American countries, the product-market focus rapidly shifts to 3MW and the largest 4-5 MW models. Several WindEnergy Hamburg exhibitors have concrete objectives for this emerging fast-growth market.

Known current bottlenecks include an inadequate port infrastructure and the unavailability of suitable special cranes which are needed because of the very high mean wind speeds of up to 12 m/s in the country’s South. To avoid costly downtime during installation because of weather, Enercon will employ innovative climbing crane and bolted-steel tower technology in Argentina which it recently acquired after buying the Dutch company Lagerwey. Furthermore, Enercon will introduce the new 4 MW E-126 EP3 in the country.

Another example of new materials and methods in focus for mature as well as emerging onshore markets is the use of concrete towers in Brazil due to high steel prices in the country. German exhibitor Max Bögl Wind has for many years supplied its proprietary concrete-and-steel hybrid towers with hub heights of up to 180m, especially for low-wind projects in Germany. The cost-effective use of high towers raises yields by 0.75 – 1% for each extra metre added, thanks to stronger and more stable wind speeds at greater heights. The company introduced its high-rise towers to the US earlier this year and already produces them in Thailand using a pre-fabricated mobile factory for the first time which the company developed in-house.

WindEnergy Hamburg and Husum Wind

The world of wind energy gathers in Hamburg for the Global Wind Summit every two years.

The Global Wind Summit will be held in Hamburg, the capital of the wind industry, from 25 to 28 September 2018. At WindEnergy Hamburg, roughly 1400 exhibitors from around the world will present their product innovations and projects. The world’s leading wind industry expo for the onshore and offshore wind industry mirrors the global market and its entire value chain.

In parallel, WindEurope will hold the Global Onshore and Offshore Conference in the halls of Hamburg Messe. In several sessions at the global WindEurope conference in Hamburg, industry visitors will learn more about how to compete successfully in auction-driven markets. The third day of the conference will feature workshops and lectures on topics such as “Designing auctions: What we have learned and where we should go”, or “Risk mitigation in a merchant world” and “Under pressure? The impacts of LCOE reductions on the supply chain”.

The CL-Windcon project has recently celebrated its third General Assembly Meeting in Pamplona, hosted by CENER (National Renewable Energy Centre of Spain). During the event, the partners have showcased the main advances of this European project, focused on a new way of approaching the design and operation of a wind farm, based on the wind farm closed loop control paradigm.

Representatives of the 15 organisations which conform the consortium have taken part in this encounter: General Electric, Ramboll, University of Stuttgart, Technical University of Munich and UL International GmbH / DEWI from Germany; Enel Green Power and Politecnico di Milano from Italy; Aalborg University from Denmark; Delft University of Technology and the the Energy research Center of the Netherlands (ECN part of TNO), Garrad Hassan from the United Kingdom, as well as the Spain´s entities Ikerlan-IK4, Qi Europe, ZABALA Innovation Consulting and CENER as project coordinator. Throughout two days, the most important milestones of the project were shared and discussed.

CL-Windcon is funded by the Framework Programme for Research and Innovation Horizon 2020 of the European Union (agreement nº 727477) and will last until October 2019. The initiative has a total cost of 4.9 M€. The CL-Windcon project is fully aligned with the objectives of the Energy Transition and policies to face the climate change challenge driven by the European Union.

Up to this moment, CL-Windcon project has performed developments over wind farm models, which now conform a set of multi-fidelity tools of wide application to wind farm control design and validation.

Furthermore, because additional cyclic loads are generated when the blades of a wind turbine enter into an upwind turbine wake, CL-Windcon has developed (i) estimators for partial wake overlap detection to be used for triggering countermeasures for reducing wake-generated loads, (ii) a novel closed-loop wake steering methodology, as well as (iii) an individual triggerable pitch control. Additionally, reliability enhancing techniques for management of sensor failure based on sensor redundancy have been proposed for generator speed measurements.

Moreover, validation activities for the turbine control strategies and supporting technologies developed in CL-Windcon have been made. Apart from simulation analyses, three wind tunnel testing campaigns have been performed so far and the fourth one is expected to take place in the following weeks. Instrumentation at the full-scale wind farm has taken place, too.

Finally, the activities for the feasibility assessment of the proposed technologies has already started setting the basis for the common approach. This will allow a sound analysis under different perspectives such as O&M, technology at turbine and farm level, redesign, Life Cycle Cost (LCC), Life Cycle Assessment (LCA) and LCoE evaluations, or wind power standards.

The CL-Windcon project includes other transversal activities focused on the dissemination and communication activities and the exploitation of results. The main goal of such activities is to spread the word about the project among the stakeholders of the wind energy sector, policy makers and the general public. The exploitation of results strategy aims to bring to the market the main applications of the project for the sector.

The next steps of the project will be the classification of models and generation of wind farm control, the implementation of high fidelity simulations, the preparation of the wind field experiments, follow up with wind tunnel campaigns and the advance on the feasibility studies. All the progress will be reviewed in next general assembly meeting to be hosted by Polimi at Milano next October 2018.
