The Energy Division of Acciona has developed a pioneering solution at global level in the field of hybridization between wind and photovoltaic power. It consists of covering a wind turbine tower with flexible organic panels to produce energy for the internal electricity consumption of the turbine. The innovative project will allow the study of the performance of the organic panels -an emerging photovoltaic technology- and their application to improve wind turbine efficiency.

The system has been installed in one of the turbines of the Breña Wind Farm (Albacete, Spain), which ACCIONA owns and operates. The turbine is an AW77/1500 of Nordex-Acciona Windpower technology, mounted on an 80-metre-high steel tower (hub height).

Installed on the tower are 120 solar panels facing southeast-southwest to capture the maximum of the sun’s rays throughout the day. They are distributed at eight different heights, occupying around 50 metres of the tower’s surface area. The photovoltaic modules, with an overall capacity of 9.36 kWp, are of Heliatek technology (HeliaSol 308-5986 model). They are only 1 mm thick, and each one has a surface area of 5,986 x 308 mm.

In contrast to the conventional technology used in the manufacture of photovoltaic models based on silicon, these organic panels use carbon as raw material and are characterized by their structural flexibility, which makes them adaptable to very different surfaces. Other key features are lower maintenance costs, less energy consumption during manufacture, easier logistics and the complete recycling of the materials used, although their efficiency is still below that of silicon modules.

“The hybridization project in Breña means the optimization of the use of space for renewable energy production and it will enable us to test the efficiency of organic photovoltaics, a technology that we believe has one of the best improvement curves in terms of technological efficiency. That is why we have decided to pilot it”, says Belén Linares, Energy Innovation Director in Acciona.

Optimizing generation

The immediate application of the Breña project is to produce part of the energy that the internal systems of the wind turbine need. When the turbine is running, some of the energy generated is used to power the auxiliary systems. In shutdown mode, certain systems need to continue functioning so they are fed from the grid, which means that the wind turbine is registering a net consumption of energy.

The new photovoltaic system with panels on the tower will be able to cover, completely or partially, the energy demand related to the operation of the wind turbine when there is solar radiation, or even -in a possible later phase of the project- when the sun is not shining. This would be done through a battery storage system, leading to an improvement in the net production sent to the grid.

The organic panels are connected to two inverters that convert DC into AC for later connection to the grid which supplies the electrical equipment of the wind turbine.

The entire system is monitored with a view to evaluating it under real conditions, both from the point of view of energy production and degradation of the solar modules. Conceptually, it is a very innovative design in relation to previous experiences in wind power-photovoltaic hybridization, based on panels installed on the ground.

The idea is part of a wide-ranging innovation project driven by Acciona to study a number of emerging photovoltaic technologies, with the aim of pioneering the adoption of more efficient solutions in each case and consolidating its leadership as a PV developer. The company currently has over 1,200 MWp in operation or under construction in different parts of the world.

Following the launch of the EnVentus platform in January, including the V162-5.6 MW and V150-5.6 MW turbines, Vestas today introduced the V138-3.0 MW turbine at AWEA WINDPOWER in Houston, Texas. Based on the scalable EnVentus platform architecture, the V138-3.0 MW’s 138m rotor provides a large rotor-size-to-generator-rating ratio, strengthening Vestas’ portfolio of turbines through superior park level energy production, higher certainty in performance, and reduced levelised cost of energy.

The V138-3.0 MW is globally applicable but purposely designed to maximise performance under market specific constraint conditions. By combining the V138-3.0 MW turbine’s 138m rotor with an 83m tower, the new turbine offers the industry’s largest swept area under 152.4 m (500ft), a relevant height constraint in the United States. At the same time, the turbine’s leading sound power levels makes it highly suitable for low wind sites in sound sensitive markets such as France.

Chris Brown, President of Vestas’ sales and service division in the United States and Canada says: “The V138-3.0 MW underlines Vestas ability to continuously innovate and lead the industry in developing customisable and sustainable energy solutions that meet our customers’ needs. This turbine is a perfect match for the North American market where higher certainty in Annual Energy Production at park level will become increasingly important for our customers to secure project financing and ensure profitability in a post-PTC market”.

As wind energy continues to expand globally and increase its share of the energy mix, the energy market is transforming. EnVentus is designed to meet the challenges our customers are facing in this environment, including changing energy policy and grid requirements. Through increased standardisation of components while ensuring turbine optimisation, the EnVentus variants thus help efficiently ensure our customers’ competitiveness in a wide range of market conditions, including markets driven by auction and forward-selling.

Anders Vedel, Vestas Chief Technology Officer, says “With the introduction of the V138-3.0 MW, we take another step forward in versatility and scalability of functional systems, demonstrating modular product development’s huge potential and how it supports our vision to become the global leader in sustainable energy solutions. I’m proud that, by utilising many of the same components as the first two turbines, we can introduce the V138-3.0 MW to meet customer requirements while lowering the levelised cost of energy and optimising the value chain”.

With the introduction of the V138-3.0 MW, EnVentus now covers an unprecedented wide spectrum of turbine generator ratings and rotor sizes, underlining the scalability of EnVentus’ platform architecture. Prototype installation is expected by the second half of 2020, while serial production is scheduled for the first half of 2021.

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.

Vestas Wind Systems A/S has re-established itself as the leading manufacturer for wind turbines with over 10 GW, or 19.6% share, of global installations in 2018, according to GlobalData.

According to Vestas, high level of project commissioning in Americas, Europe, and steady installation activity in Asia-Pacific has aided the company to cross the 10 GW mark for the first time.

In second position was China’s Xinjiang Goldwind Science & Technology Co., Ltd. with over 7 GW of installations, representing around 13.7% share of the annual installations globally. Goldwind maintained its leading position in the domestic market with over 6 GW of installations in China.

Siemens Gamesa Renewable Energy SA (SGRE), which topped the 2017 ranking fell three places and is currently occupying third position. SGRE installed 6.1 GW, with 11.8% share, of the global wind turbine installations for 2018. The fall in the installed capacity, from 9.4 GW in 2017 to 6.1 GW is mainly attributed to a large number of turbines delivered to projects that are still under construction and expected to come online in 2019-20.

GE Renewable Energy remained in the same position, with over 5 GW of turbine installations in 2018. The company stated that the limited growth was due to pricing pressure, shrinking domestic market and an unfavorable business mix.

Envision Energy Limited occupied fifth in the ranking, gaining two places compared to 2017’s ranking with around 3.7 GW of installations, representing 7.2% of the share. Envision Energy continues to remain second in the domestic Chinese market.

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.

Developers commissioned a little over 45 GW of onshore wind turbines globally in 2018 compared with 47 GW a year earlier, a 3% decline partly due to a slowdown in India and Germany. Just four manufacturers accounted for more than half, or 57%, of the machines deployed: Denmark’s Vestas, China’s Goldwind, GE Renewable Energy of the U.S. and Spain’s Siemens Gamesa.

The latest data from BloombergNEF (BNEF) show that Vestas extended its lead in the industry, with 10.1G W of its onshore turbines commissioned in 2018 – a global market share of 22% compared with 16% in 2017. The statistics draw on BNEF’s global database of wind projects and extensive information from the industry.

Goldwind rose from third to second place, lifted by a strong performance in China, where it captured a third of the 19.3 GW market. The company’s global footprint, however, remains limited: only 5% of Goldwind’s 6.7 GW were commissioned outside China. GE came third with 5 GW – six out of every ten GE turbines were commissioned in the U.S. Both GE and Vestas commissioned just over 3 GW in the U.S.

Siemens Gamesa dropped from second to fourth place, with 4.1 GW commissioned in 2018. This is 40% less than in 2017, although the tally does not include a number of very large wind farms that are only partially built and will not come online until 2019.

Chinese manufacturers rely almost solely on their home market. Of the European onshore wind turbine makers to make the top 10, Vestas and Nordex actually commissioned more capacity in the Americas than in Europe. Most of Enercon’s turbines are in Europe. Siemens Gamesa is the most diversified, with a near equal split across Europe, the Americas and Asia.

Total onshore wind installations in 2018 were 11.7 GW in the Americas, 8.5 GW in Europe (Including Turkey and Russia ) and 1 GW in Africa and the Middle East, while Asia accounted for 24.2 GW. BNEF registered new wind farms starting full commercial operation in 53 countries.

In offshore wind, it’s been a record year for China, and we will see more growth. Some 1.7 GW of the global 4.3 GW was commissioned there. In Europe it was a tight race between Siemens Gamesa and MHI Vestas. GE has some projects coming up in France, and we also expect to see orders for their new 12 MW platform.

BNEF predicts demand for around 60 GW of onshore capacity in both 2019 and 2020 with increases in all regions. However, a lot of this impressive-sounding volume rides on extremely competitive pricing, add-on products and services, and new financing models. This will be tough to deliver for the Big Four, let alone the smaller turbine makers.

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.
