ABB’s Power Grids business has been awarded an order from the Aibel/Keppel FELS consortium, which will design, construct, and build the High Voltage Direct Current (HVDC) transmission system for the offshore wind connection project DolWin5. ABB is the HVDC technology provider. This project will deliver 900 megawatts of zero-carbon electricity – enough to power around 1 million homes – from three wind farms some 100 km off the German coast. It is scheduled for completion in 2024.

The order includes the converter platform in the North Sea, as well as an on-shore converter station located in Emden, in the Lower Saxony region of Ger-many. TenneT, a leading European electricity transmission system operator, with activities in the Netherlands and in Germany, is responsible for providing power links to the offshore wind farms in this cluster.

ABB’s HVDC solution is used to transport the power generated by offshore wind farms very efficiently by converting the alternate current (AC) to direct current (DC) on the converter platform. That makes it possible to transmit the power through a 130-kilometer-long DC cable system with very low losses to the mainland. In the onshore converter station, the power is converted back to AC and then integrated into the transmission grid. ABB HVDC’s offshore wind connection solutions are compact and modular to specifically address the challenges of the offshore wind industry and support a substantial improvement in LCOE (Levelized Cost Of Electricity), as well as carbon foot-print.

With the use of ABB’s voltage source converter technology, commercialized under the name HVDC Light®, it is possible to keep the conversion losses very low. Additionally, the order will also include the ABB Ability™ Modular Advanced Control for HVDC (MACHTM), which is instrumental in controlling the complex connection between wind farms and the on-shore AC grid.

As part of its energy transition (“Energiewende”), Germany’s plans to generate 65 percent of its power from renewable sources by 2030. A rapidly growing pro-portion of this clean energy is generated in huge offshore wind farms in the North Sea. In just 10 years, Germany’s offshore wind production has grown from zero to 6,382 MW, making it the world’s second largest offshore wind pro-ducer after the UK.

Atos has announced that it has offset 100% of its 2018 CO2 emissions worldwide, through a dedicated wind farm program. In addition to offsetting emissions from its data centers, which it has done since 2014, Atos now ensures that this program also includes the offsetting of carbon emissions produced by its offices and business travel. This initiative is part of Atos’ global environmental program supporting Advance 2021 strategic plan.

As part of the world effort to tackle climate change, Atos is working to continuously reduce its environmental footprint through the implementation of its environmental program with multiple initiatives, including modernizing its data centers, increasing the use of renewable energies, reducing its carbon footprint and improving its overall energy efficiency.

To offset its CO2 emissions from all its activities, Atos has invested in three wind farms located in India. The project, which was started in 2010 across three states in India (Karnataka, Gujarat and Maharashtra), promotes the use of renewable energy and has led to the installation of a total of 137 wind turbines generators.

Every year, the three wind farms with an output 109.6 MW, produce power approximately 40,000 households in rural areas. They improve the production capacity of the local industries and businesses and contribute to the development of the local economy – providing new jobs – and to education and healthcare initiatives.

Atos is supporting businesses in their journeys towards more sustainable operations. Going forward, Atos’ clients can report “ZERO” in their own carbon reporting for the solutions they host in Atos datacenters.

Since 2008, Atos has rolled-out a major environmental program that encompasses the modernization of our datacenters and the reduction of their Power Usage Effectiveness (PUE), the increasing use of decarbonized electricity and a global offsetting program. Within our Advance 2021 strategic plan, we are committed to reducing our carbon emissions by revenue up to 20% (2016 baseline) in order to help tackle climate change. We are therefore proud to be now delivering fully compensated hosting services to our clients.” says Philippe Mareine, Head of Corporate Social Responsibility at Atos.

So that this project conforms to the VCS standard, Atos has chosen to work with EcoAct.

As a leading carbon neutrality advisory company, EcoAct is very proud to support Atos in the implementation of its carbon neutrality strategy – especially as they expanded the scope of their carbon offsetting in 2018 to their offices and business travel worldwide, in addition to their datacenter emissions” says Arnaud Doré, Executive Director at EcoAct France.

Over the long-term, Atos’ carbon reduction targets have been approved by the Science-Based Targets initiative (SBTi) as in line with the global effort to limit the rise of climate change below 2°C.

The Wind Energy area of CENER (National Renewable Energy Centre of Spain) will have a very active presence in the next edition of WindEurope 2019, both at the congress and at the exhibition, to be held this week in Bilbao between 2nd and 4th of April. This is one of the most important annual events in the sector, since it is expected that there will be around 8,000 visitors and that more than 300 exhibitors will participate

CENER at the Conference

Specifically, CENER researchers will present two papers and 4 posters at the conference and will coordinate a workshop. The workshop, which will be held today Tuesday, April 2nd, will deal with the European NEWA project (ERA-Net Plus NEWA number 618122), will be coordinated by Javier Sanz (project coordinator in Spain) and Roberto Chavez will also participate.

The two papers will be presented on Wednesday, April 3rd: Roberto Chavez will talk about a new method of coupling mesoscale and microscale models for the evaluation of wind resource, and Álvaro González will talk about digital copies of wind turbines for the management of his useful life.

In addition and as usual in this type of congresses, posters will be shown with explanations by responsible researchers. In the case of CENER, are 4 in total. Today, Tuesday, April 2nd, José Azcona will comment “Scaled wave tank hybrid testing of the TELWIND Floating platform for a 5 MW wind turbine”. On Wednesday Beatriz Méndez will also intervene with the “New low-drag vortex generators concept”.and Álvaro González will present “Development of a panel code and integration into OpenFAST” and also the poster “Digital twin of a real wind turbine: development and validation”.


In parallel to the congress the exhibition is celebrated, in which CENER participates with a stand (F1-52), where some of its main proposals will be shown around four main areas: wind resource assessment, aerodynamics, structural design, and management of wind farms, including their life extension. Every day of the event, oral presentations will take place at the stand.

In the area of ​​wind resource assessment, CENER has designed a tool that uses Computational Fluid Dynamics (CFD) technology together with the computational cloud, and the latest results of the European NEWA project (ERA-Net Plus NEWA number 618122), whose main objective is the realization of a wind atlas in Europe that will include the state of the art in the modeling of the wind resource, as well as the generation of an experimental database created from intensive measurement campaigns. CENER is the project coordinator in Spain.

In addition, the proposed innovations in aerodynamic design and the improvement of the efficiency of wind turbine blades will also be presented at the stand. Regarding structural improvements, CENER proposes an innovative solution for the modular union of the blades, as well as new testing methods for offshore wind platforms. The management of wind farms and their extension of useful life is another main issue that will lead CENER to Bilbao, proposing different strategies for different types of turbines within the same wind farm, thus optimizing the assets.

As expected, the Wind Turbine Test Laboratory will also have a special role at the stand of CENER in Wind Europe 2019, which will be located in Hall 1, F1-52.

According to data from the Brazilian Wind Power Association, ABEEólica, Brazil ended 2018 having achieved 14.71 GW of wind power capacity installed over 583 wind farms and more than 7,000 wind turbines distributed between 12 states.

From January to November 2018 (data available as of today) wind power generation rose to 44.62 TWh, meaning that the existing wind power stock injected into the grid the equivalent of the average monthly consumption of over 23 million homes (70 million people).

In addition to the 14.71 GW of installed wind power, a further 4.33 GW are already under construction or in the pipeline. This means there will be at least 19.04 GW by the end of 2024, only taking into account contracts already confirmed by the auctions, public tenders for the free market, as well as contracts signed to date.

Considering the Brazilian electricity mix in December 2018, wind power enjoyed a participation of 9%, as the third most representative source. The second source, biomass, accounted for 9.1% of the mix as at the end of 2018. Wind power will soon overtake biomass to rank second in the Brazilian electricity mix, a truly historic fact for an energy source that has only been more intensively developed for little under ten years. At the start of 2011, Brazil had less than 1 GW of wind power. In 2012, the country was 15th in the Global Wind Energy Council’s installed wind power capacity ranking. It is now on track to 15 GW and achieving 8th place in the world ranking.

As regards its contribution, wind power covered almost 14% of the SIN, the National Interconnected System, during periods recorded from June to November. The monthly information bulletin from the National System Operator for September, for example, shows that on Wednesday, 19 September, wind power achieved a record share by responding to 13.98% of domestic demand.

In the specific case of the Northeast region, demand coverage records already exceed 70% on a daily basis. The most recent record in the region was set on Sunday, 13 November, when the entire sub-system was covered by wind power and although some power was exported, the 8,920 MW output covered 104% of demand with a capacity factor of 86%. On that same date, in addition to one-off record, it is worth noting that wind power covered 100% of demand over a period of two hours. It is also important to mention that, at different times, the Northeast has assumed the role of energy exporter, a reality that is completely the opposite to the history of the sub-market that is a natural energy importer.

2018 contracts

Two new power auctions, known as A-4 and A-6, took place in 2018 and wind power was present in both. In the A-4 auction that was held on 4 April, four projects were awarded (114.4 MW of capacity and 33.4 MW under the physical warranty mechanism for assured energy availability) that must start supplying electrical power as from 1 January 2022. The A-6 auction, held on 31 August, awarded yet more capacity with 48 wind power projects (1,136.30 MW of capacity and 420.10 MW under the physical warranty mechanism). Under this auction, plants must start commercial operations as from 1 January 2024. In total, the 2018 regulated auctions awarded 1.25 GW to 48 wind farms.

Brazil also recorded a good year on the open market, given that at least three major auctions took place promoted by CEMIG (2 auctions) and Casa de los Vientos, designed to commercialise renewable energy. Although the figures for these auctions have not been divulged, ABEEólica estimates that, overall, wind power companies sold around 2 GW on the free market in 2018, which proves that this is a significantly expanding market for the sector.

Taking into account the contracts awarded by the auctions and sales estimates for the free market, total estimated contracts for 2018 amounted to 3.2 GW.

The European Investment Bank (EIB) has granted its first EIB Green Loan to Endesa. This financing aims to make it easier to invest in energy efficiency and renewable energy sources. Although the EIB has financed a number of projects of this kind in its long history of combating climate change, this is the first time it has described a loan in this way, thereby helping promoters such as Endesa to develop their decarbonisation strategy.

The operation signed covers EUR 335m in financing to build 15 wind farms with a capacity of 446 MW and three solar photovoltaic plants with a capacity of 339 MW.

The EIB Green Loan will finance operations that are fully in line with the requirements set out in its Climate Awareness Bonds programme, and as a result is likely to be allocated to its portfolio of loan operations financed via the issuance of these bonds.

The EIB financing will also help achieve the objectives of the Spanish National Action Plan for Renewable Energies, which states that 20% of the energy used in Spain in 2020 must come from renewable sources.

Endesa was awarded 540 MW of wind energy and 339 MW of photovoltaic energy in the auctions for new renewable electricity generation facilities that took place in Spain in May and July 2017, which will involve an investment of over EUR 800m until 2020.

Endesa’s wind farms and solar power plants will be built in various areas across six autonomous communities: Aragón, Castilla-La Mancha, Castilla-León, Extremadura, Galicia and Murcia. The project will also help to create jobs: the construction of the wind farms and photovoltaic plants is making it possible to employ 1 700 people to work on the project during the investment phase and up until implementation.

The total contribution of the wind power sector to GDP for the period 2012-2017 was €16.379bn. In 2017, the direct contribution to GDP amounted to €2,300.8 million, representing an increase of 57% on 2016 results. This one of the main conclusions taken from the new edition of the ‘Macroeconomic Impact Study of the Wind Power Sector in Spain’, drawn up by consultancy Deloitte, which provides a detailed analysis of Spain’s wind power sector over the last two years, 2016 and 2017, as well as for the previous period 2012-2015. So that wind power remains an important sector for the Spanish economy, it is necessary to make progress in five key areas: regulatory stability; long-term visibility; the formulation of an appropriate system that guarantees reasonable profitability; an auctions system with an established calendar; and regulation to repower and extend the service life of wind farms.

Walmart and EDP Renewables (“EDPR”) announce three power purchase agreements (PPA) that will enable the construction of three new utility-scale wind farms – developed, owned, and operated by EDPR – in the states of Illinois and Indiana. Walmart’s cumulative 233 megawatt (MW) investment includes the following:

•123 MW from the Bright Stalk Wind Farm (a 205 MW project in McLean County, Illinois, with start of operations expected in 2019; this PPA is a part of the announcement EDPR issued on July 3, 2018)

•60 MW from the Headwaters II Wind Farm (a 200 MW project in Randolph County, Indiana, with start of operations expected in 2020; this PPA is a part of the announcement EDPR issued on July 3, 2018)

•50 MW from the Harvest Ridge Wind Farm, formerly Broadlands Wind Farm (a 200 MW project in Douglas County, Illinois, with start of operations expected in 2019; this PPA is a part of the announcement EDPR issued on May 10, 2018)

Walmart’s purchase through these agreements will produce enough electricity to power more than 60,000 average homes in Illinois and 15,000 average homes in Indiana with renewable energy each year. Additionally, these wind farms will bring economic benefits to their respective regions and states in the form of jobs, landowner and tax payments, and money spent in local communities.

The declining cost of renewable power has led to an increase in clean energy procurement from companies like Walmart in recent years. The continued commitment from corporate entities in procuring renewable energy speaks volumes about the importance and value of securing fixed, competitive pricing over the long-term.

To date, EDPR operates 797 MW of wind energy projects in Illinois and with the addition of the Bright Stalk Wind Farm and the Harvest Ridge Wind Farm, EDPR will further increase its footprint in Illinois, surpassing 1,200 MW, or 1.2 gigawatt (GW), of operational capacity by the end of next year.

EDPR also operates 801 MW of wind energy projects in Indiana. With the completion of the construction of the 200 MW Meadow Lake VI Wind Farm, EDPR will exceed 1,000 MW, or 1 GW of operational capacity by the end of 2018. The company will continue to add to its renewable energy portfolio in the state in the coming years with the addition of the Headwaters II Wind Farm and the 200 MW Riverstart Solar Park that are expected to be operational in 2020 and 2022 respectively.

EDPR North America operates more than 5,600 MW of renewable energy projects.
