Foundation of a wind turbine

GES, an integral supplier of engineering, construction and maintenance for renewable energy projects (wind, solar and hydroelectric) will build the Valdejalón wind portfolio consisting of 5 wind farms in Aragón, Spain. Once completed, the wind farms will have a total installed capacity of 231 MW. Construction is expected to be finalized in 2020 second quarter.

The project is divided into two phases: Valdejalón East which includes the wind farms El Cabezo (49 MW) and Portillo II Phase I (45.6 MW) and Phase II (38 MW), and Valdejalón West composed of Virgen de Rodanas I (49.4 MW) and Virgen de Rodanas II (49.4 MW).

The Valdejalón portfolio is fully owned by the Danish fund manager Copenhagen Infrastructure Partners P/S (CIP) through its fund Copenhagen Infrastructure III K/S (CI-III). CIP is a fund management company focused on energy infrastructure including offshore wind, onshore wind, solar PV, biomass and energy-from-waste, transmission and distribution, and other energy assets like reserve capacity and storage. The company operates in Europe, North America and Southeast Asia.

GES is responsible for the engineering, procurement and construction of the project. The company is already working in the detail engineering, and will be in charge of the complete BOP (Balance of Plant), both the civil work, with more than 60 km of roads and 61 foundations and platforms for the 85 m wind turbines to be installed in the park; and the electrical work, including the underground medium voltage network with more than 55 km of trenches and the 132 kV evacuation line of almost another 50 km, which will connect the two new substations to an existing interconnection substation.

Historically, O&M in the PV sector was seen as the little brother of wind power, where the requirements and types of companies varied widely among themselves. However, due to the maturity of the sector, the need to optimise procedures, the typology of the owners and in general, the increase in the size of PV plants (plants of almost 500 MW are currently being built), the O&M of PV plants is being exposed to the changes that have provided the wind power sector with a degree of professionalism and specialisation…By Íñigo Vázquez, Iñigo Vázquez, Chairman of AEMER, the Spanish Association of

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.

50 N117/3600 turbines ordered by Vattenfall

Vattenfall, owner of the Dutch utility Nuon, has signed a contract for the delivery of 50 N117/3600 wind turbines with the Nordex Group in Amsterdam. The Wieringermeer wind farm is one of the biggest onshore projects for Vattenfall in Europe. The wind farm has an above-average capacity factor of 42 per cent due the excellent average wind speed of 8.6 m/s combined with the highly-efficient Nordex N117/3600 wind turbine. Due to the low noise emissions, the wind turbines can run without curtailments at full rated power, having a positive effect on the expected energy yield. The relatively low sound power level of the N117/3600 is achieved thanks to the wind turbine design and the addition of serrations to the rotor blades.

Sustainability is an important part of our DNA. This is why we are striving for sustainable solutions in different areas,” explains Patxi Landa, Chief Sales Officer for Nordex SE. This includes the interests of the immediate neighbourhood as well as the CO2 emissions that can be avoided. Located 60 kilometres north of Amsterdam, the site is subject to noise emission restrictions, which the turbines are able to meet. At the same time, the wind farm will prevent the emission of around 300,000 tons of carbon dioxide annually which would otherwise be produced by a mix of gas and coal-fuelled power stations.

Installation of the 50 wind turbines will commence from March 2019 and be completed by the end of the year respectively. Thereafter, the Nordex Group will provide service for the wind farm and establish a local service station for this purpose. “Everybody is looking forward to the start of this large project. We have already made the first preparations in the area and are glad to have professional companies with whom we will work closely to realize the installation of the first 50 turbines of this wind farm,” explains Ruben Lindenburg, Project Director of Nuon for Wind Farm Wieringermeer.

To date, the Nordex Group has installed wind farms with a combined capacity of almost 300 MW in the Netherlands and has a dense service network for the technical management of the wind power systems in this country.

Group ACS, through Dragados Offshore, has been awarded with the development, construction and supply of the HVDC electric power converter platform for Dolwin 6 project in the North Sea. This project will be developed in partnership with Siemens, and it will be able to transmit enough electricity to initially supply one million German homes.

The system with 900 megawatts of power consists of a HVDC offshore converter platform in the German North Sea and an onshore HVDC substation, in Emden area.


Particularly, Dragados Offshore will be in charge of the design, supply, construction, transportation and installation of the platform, while Siemens will cope with the design and supply of HVDC equipment for both substations, and the development of the onshore substation. They will together commission the facilities so as to test them and put them to work.

The offshore conversion platform transforms the electrical energy of incoming wind turbines by high-voltage 155 kV AC power cables to high voltage direct current of 320 kV, exporting it to the ground substation. The platform will be connected to the existing Dolwin Beta platform.

The contract is considered as an important milestone for ACS, and subsequently for Dragados Offshore, as it strength’s their activities in the providing of platforms for the offshore wind industry by building a state-of-the-art megaproject in its sector, consolidating it in a Leading position in the offshore market.

From the deep fjord outside Stord on the west coast of Norway, the floating wind turbines will be towed to Scottish waters. The world´s largest floating wind project will be located 25 km off the coast of Peterhead in Aberdeenshire, Scotland, at water depths between 90 and 120 m.

The floating foundations in the Hywind project are ballast-stabilized and anchored to the seabed with mooring lines. With their lightweight nacelles, Siemens Gamesa large direct drive wind turbines are particularly suited for floating foundations.


The Hywind concept has already proven its effectiveness in 2009, when Statoil and Siemens Wind Power successfully installed a 2.3 MW Siemens Wind Power turbine at the first full-scale floating wind turbine project worldwide, Hywind Demo.

At the same time, Siemens Gamesa gathered a lot of experience on the specific requirements regarding the control parameters on a moving wind turbine under offshore conditions. For the floating installation, the technicians developed new controller algorithms for rotor pitch and yaw drive regulation.

The most important key success factor for the future of floating wind turbines is concepts which are cost (LCoE) competitive with bottom fixed foundations.
In the Scottish pilot project Siemens Gamesa and Statoil have been working close to develop a concept for commercial and large scale offshore wind parks which is cost efficient and with low risk.

Commissioning of the Hywind project is planned for 4Q17.

The majority of operating floating wind farms are currently located in Europe. However, California, Hawaii, Japan and Taiwan are attractive geographies for floating wind power turbines in the future.

The global wind operation and maintenance (O&M) market is set to grow from just over $13.7 billion in 2016 to around $27.4 billion by 2025, representing a compound annual growth rate of 8.0%, according to research and consulting firm GlobalData.

The company’s latest report states that the O&M of a wind farm is essential as it contributes to value creation, increases turbine availability, and improves returns. Aging wind turbines and the failure of components such as blades and gearboxes are the major driver of the burgeoning market.


Anchal Agarwal, Power Analyst for GlobalData, explains: “Offshore wind accounted for just over 8% of the total wind O&M market in 2016, and is expected to contribute 18.4% by 2025. This is because the technology is increasingly being explored across the world, for its high yield, due to stronger and more consistent winds in comparison to onshore; and has the scope to construct massive Gigawatt-scale projects.

Indeed, offshore wind attracts higher O&M costs than onshore wind due to higher turbine maintenance, higher logistics costs, and a lack of skilled manpower.

China is the largest wind O&M market in the world and accounted for 30% of the global market size in 2016. GlobalData expects that the country will maintain its leading position, with a share of 27.4% in 2025. Increasing installations of wind power will provide opportunities for O&M in the forecast period. A large installation base, government plans, and strict environmental laws are the major drivers for the growth of the country’s wind power market.

The US is the second-largest wind O&M market, with a share of 14.6% in 2016, and is also expected to maintain its position in 2025. Germany – the largest European wind O&M market – accounted for 14.3% of the global market in 2016, and is expected to hold an 11.9% share in 2025. The major reason for key countries losing their market share is the emergence of newer markets, such as India and the UK. India’s share of the global wind O&M market is expected to increase from 5.6% in 2016 to 6.4% in 2025, while the UK’s share will increase from 5.3% to 7.1% over the same period.
