With the official signing of the wind turbine order with Siemens Gamesa the developer and operator
Ørsted has now kicked off the largest offshore wind farm to date. Once commissioned in early 2022
Hornsea Two will provide clean energy for approximately 1.3 million British households. The
installation of the 165 large direct drive wind turbines at the project site 89 kilometers off the British east coast is expected to start in 2021.

The record-breaking project with a combined rating of 1,386 MW is not only the
largest wind project in Siemens Gamesa’s history, but also the largest single order in the history of
offshore wind energy. So far, this leading position has been defended by Hornsea One with a capacity
of 1,218 MW and which similarly was developed by Ørsted and is currently under construction.

The nacelles for Hornsea Two will be produced at SGRE’s innovative factory in Cuxhaven, Germany,
while the majority of the blades will be made at the factory in Hull, UK, where the pre-assembly work
will also be carried out. Towers are expected to be partly sourced from UK suppliers. A single 8-MW
turbine is capable of generating enough electricity for over 8,000 average European households.
Originally planned for up to 300 turbines Hornsea Two has been adapted to the progress of the
significantly more powerful hardware. With only 165 units at the same total output, the project benefits from significantly improved economic efficiency and simultaneously reduced LCoE.

The new SG 8.0-167 DD is equipped with a rotor 167 metres in diameter. The blades, 81.5 meters
long, deliver an 18% wider swept area and 20% more annual output than its predecessor, the SWT-
7.0-154. It features the technology proven in the direct drive platform combined with a larger-scale
rotor in order to offer customers higher returns while minimising the associated costs and risks.

The innovative 28 MW offshore wind power project located in the waters of North-western Denmark is fullyoperational, producing power for customers Nissum Bredning Vindmøllelaug and Jysk Energi since early 2018. Utilizing the first serial-manufactured SWT-7.0-154 direct drive offshore wind turbines, the project is a showcase of Siemens Gamesa’s commitment to innovation and reducing costs. The wind turbines and further technological advancements have fulfilled expectations and are now in preparation to become available for commercial deployment.

Nissum Bredning Vind is a small project capacity-wise, especially when compared to other offshore wind power projects. But it is extremely significant in terms of innovation. Siemens Gamesa has tested and validated several new technologies here, from a 66 kV transmission system to jacket foundations with concrete transition pieces to a cable-in-pipe installation. These innovations all share the common goal of reducing the Levelized Cost of Electricity (LCoE) from offshore wind

Cost reductions of up to 30% compared to traditional elements can be provided by some of the elements installed at Nissum Bredning Vind. The innovative cable-in-pipe installation, where standard onshore cables are installed in plastic pipes from the mainland as well as between the wind turbines, lowers capital expenditures compared to employing offshore cables. Gravity jacket foundations provide a soil interface at normal water depths which can be made more cost-efficient versus classic jacket foundations. Furthermore, the concrete transition piece can be made at a cost level of up to 30% lower than a steel transition piece. Also, the 66 kV transmission system reduces transmission losses, providing the customer with a higher energy output – and thus higher revenue – from each wind turbine.

Iberdrola shall implement the ROMEO project at its Wikinger offshore wind farm, one of the most ambitious R&D initiatives at this time for improving efficiency in the offshore wind energy sector.
Wikinger will be the test scenario for one of the three pilot projects being undertaken within the framework of this initiative, which is being financed by the Horizon 2020 Programme of the European Union and led by Iberdrola.

The Wikinger wind farm, with a total of 350 MW of installed power, will be capable of supplying renewable energy to 350,000 homes, with consumption equivalent to more than 20% of the energy demand of the state of Meckleemburg and Western Pomerania, where the wind farm is located.
With an investment of around 1.4 billion euros, Wikinger will avoid the emission of almost 600,000 tonnes of CO2 into the atmosphere per year. During the wind farm’s erection, 280 piles, constructed by the Asturian company Windar, were fixed to the seabed. Furthermore, 70 jackets (foundations) were manufactured by the Spanish company Navantia, at Fene’s shipyards in A Coruña, and by the Danish company Bladt, at Lindo, Denmark. Regarding the turbines, 5 MW unit capacity model AD 5-135, were developed by Siemens Gamesa at its Bremerhaven and Stade plants in Germany.

A commitment to offshore wind energy

The ROMEO project, launched in June 2017, aims to reduce the operation and maintenance costs at offshore wind farms through the use of advanced monitoring strategies and systems, as well as to analyse the performance of the wind farm turbines in real time.

The consortium of the project, made up of European companies and entities covering the entire value chain of the sector, is working on the development of an analytical and management platform enabling the decision-making process to be improved and facilitating the development of current Operation and Maintenance (O&M) strategies based on corrective measures to innovative strategies in real time, and on the degradation of the components of the main wind farm structures.

Furthermore, Romeo will develop an Internet of Things and cloud-based platform which will accommodate models for diagnosing and predicting faults in the systems. This platform will promote better understanding of the real-time performance of the main wind turbine components in operation and their current status. With this system, their useful life may be extended and their operation and maintenance costs reduced.

The innovations of the project will also be tested at the Teeside wind farms already in operation in East Anglia 1, the latter also owned by Iberdrola.

The ROMEO project, due for completion in 2022, consists of a consortium made up of 12 entities from 6 EU member states and one associated country. In addition to Iberdrola Renovables Energía, which will lead the project, the consortium will include major companies (Electricité De France, ADWEN, Siemens Gamesa, RAMBOLL, IBM Research Zurich, INDRA, BACHMANN Monitoring), SMEs (LAULAGUN Bearings, UPTIME Engineering, ZABALA Innovation Consulting), and the Cranfield University.

On October 20, the first LM 73.5 P wind turbine blade successfully arrived at Castellón Port. It is the largest blade ever produced and transported through Spain. Destined for the Merkur offshore wind farm in Germany to power GE’s Haliade 150-6 MW offshore wind turbine, the 73.5 m blade began its journey at LM Wind Power’s factory in Castellón, and travelled 45 km by road to reach the port.

This new size record in Spain reflects the fast development of the wind industry to continuously introduce longer and more complex blades, designed to lower the Levelized Cost of Energy (LCOE) and serve the growing offshore market.

Castellón Plant Director, Jose Luis Grau said: “LM Wind Power’s Castellón plant was founded in 2007 starting with about 60 people and producing 37.3 m blades. Today, the factory employs more than 620 people and produces much larger blades, up to 73.5 m in length, for multiple customers. This is a strong example of how the wind industry in Spain continues to play a significant role as a source of economic development and job creation.

Laurent Verdier, GE’s Offshore Wind business Project Office Leader said, “The onshore assembly hub was opened some weeks ago in Eemshaven, The Netherlands, and is ready for receiving the wind turbine main components, including blades, and preparing the offshore installation works that is expected to start in February 2018.

In total, 198 LM 73.5 P blades will be shipped to the Merkur site. The first blade arrived ahead of schedule – with a 3.5-hour transport time – and the duration of the journey is expected to decrease as the drivers perfect their routine over the coming months.

Successfully transporting the longest blade ever produced in Spain required more than one year of planning and analysis of road conditions by LM Wind Power and GE, as well as active cooperation with the local police, Regional Government, the Minister of Fomento and the Castellón Port Authorities to prepare the route for this large cargo.

Factories, such as the one at Les Coves in Castellón, help make Spain the fourth largest exporter of wind turbines in the world, each year exporting cutting-edge technology valued at more than 3 million euros.

Merkur windfarm is located approximately 35 km north of the island of Borkum, Germany, in the North Sea, and consist of 66 turbines that will generate approximately 1,750 GWh annually, enough clean energy to power around 500,000 homes. When completed (end 2018), Merkur will be one of Germany’s largest offshore wind farms.

Avangrid Renewables, subsidiary of Avangrid Inc. (a company of the Iberdrola Group), and Vineyard Wind have announced today a strategic partnership to develop a large-scale offshore wind power project. Vineyard Wind will be built off the coast of Massachusetts in the USA. Avangrid Renewables has acquired 50% of Vineyard Wind, the project’s promoter, from Copenhagen Infrastructure Partners (CIP).

Work on the Vineyard wind farm will start in 2020. Its final capacity will be decided on the basis of technical studies and local characteristics. This is a major strategic cooperation agreement. The knowledge about renewable energy in the USA held by Avangrid Renewables, combined with the experience in infrastructure funding of Copenhagen Infrastructure Partners and Iberdrola’s expertise in offshore wind power projects, makes up for a major competitive advantage. And this will allow Vineyard Wind to build the first offshore wind farm project in Massachusetts (and the USA).


In the summer of 2016, new regulations entered into force in Massachusetts which stipulate that power companies acquire the production of up to 1,600 megawatts (MW) from offshore wind farm facilities within 10 years. As a result, competition amongst promoters of technology is now fierce. As of this date, only three companies have acquired rights to build in the state’s maritime zone, including Vineyard Wind. Its concession is 15 miles south of Martha’s Vineyard island.

Iberdrola already holds a portfolio of major projects in this sector in Europe: the United Kingdom, Germany and France. Also, Avangrid Renewables (Iberdrola’s subsidiary) bought the rights to develop a project in the Kitty Hawk area, off the coast of North Carolina, during an auction in mid-March. Copenhagen Infrastructure Partners provides finance and management services for ongoing offshore wind farm projects in Germany and Scotland, including the Veja Mate project (402 MW) in German waters and project Beatrice (588 MW) near the coast of Scotland. The Danish company handles more than 4 billion euros in assets and acquired Vineyard Wind in August 2016.Now, experts from both companies will join the development team based in New Bedford, Massachusetts.

Burbo Bank Extension, a new offshore wind farm capable of meeting the electricity demand of well over 230,000 homes was officially opened at a ceremony in Liverpool on May, 18. The wind farm is a joint venture between DONG Energy (50%) and its partners PKA (25%) and KIRKBI A/S, parent company of the LEGO Group (25%). It is the first offshore wind farm in the world to make commercial use of the MHI Vestas V164-8.0 MW wind turbines.

Just one of these wind turbines produces more energy than the whole of Vindeby, the world’s first offshore wind farm constructed by DONG Energy 25 years ago in Denmark. This way Burbo Bank Extension showcases the rapid innovation in the offshore wind industry. Less than ten years ago at Burbo Bank, were installed the first Siemens 3.6MW wind turbines and in this short time, the wind turbines have more than doubled in capacity.


Pushing innovation in this way reduces the cost of electricity from offshore wind and will help to advance the offshore wind industry across the world. The project has also helped to develop the UK supply chain. It’s the first offshore wind farm to use UK manufactured blades and the order for transition pieces was the first for Teesside factory Offshore Structures Britain.

DONG Energy is building a new multi-million pound operations facility in Merseyside that will serve both Burbo Bank Extension and the existing wind farm in the area, Burbo Bank. Up to 75 jobs will be created during the construction of the facility, while around 45 people will be permanently employed at the site once it is operational later this year.

John Brace, Chairman of the Board of Directors of Gemini, officially opened the massive offshore wind farm on May, 8 in Eemshaven. With a 600 MW capacity, Gemini is one of the largest offshore wind farms in the world.

Gemini has been completed ahead of schedule, under budget and with an excellent safety record. Now fully operational, Gemini will produce 2.6 TWh of sustainable energy every year, reducing the Netherlands’ CO₂ emissions by 1.25 million tons. The wind farm is expected to contribute around 13% of the Netherlands’ total renewable energy supply, and approximately 25% of its wind power. Over the next fifteen years Gemini will meet the energy needs of 1.5 million consumers.


Gemini marks a turning point in the way we think about wind energy. The project’s magnitude has contributed to a rapid transformation of the sector. Today, the construction of offshore wind farms is more efficient and cost-effective than ever, and as a result there has been a significant reduction in the price of this potent renewable energy source.

Gemini is invisible from land, located 85 km off the coast of Groningen, in the North Sea. This location has some of the highest and most constant wind speeds in the North Sea, with an average wind speed of 36 km/h.

Gemini covers an area of 68 km2, and is comprised of 150 Siemens wind turbines with a capacity of 4 MW each, as well as two offshore high-voltage substations. Each substation is connected by to the land station in Eemshaven by a 110-km export cable. There, the electricity is converted to 380 kV and conveyed to the TenneT power station. Management and maintenance headquarters will be located in Eemshaven, and will create 75-100 permanent jobs.

Four companies combined forces to make Gemini possible: Northland Power (60% interest), Siemens (20%), Van Oord (10%) and HVC (10%). The construction of the wind park required an investment of 2.8 b€. The project was financed by 25 banks from Asia, Australia, Europe, and North America. To date, Gemini is the largest project financing for an offshore wind park.

The joint venture Navantia-Windar has successfully concluded at its Fene (La Coruña) facilities, the load-out of the first two spar-type floating foundations, of a series of five manufactured for Statoil’s Hywind offshore wind farm. Each of these foundations is 91 m long, 14,8 m diameter and total weight of 3450 t. The load-out of the remaining three foundations will take place at the end of May and the first half of June.

The ship used for the transport is OHT’s semi-submersible Heavy Lift Vessel Albatross. This is one of the major ships of her class, with a length of 204 m and a breath of 42,5 m. The load-out method is though self propelled modular transporters. This operation is a milestone for Navantia’s Fene yard. In order to accommodate the ship and enable the load-out, improvements have been made to the pier, access route and sea bottom.


The spar foundations will be transported to Kvaerner’s shipyard in Stord, Norway, where they will be floated out and upended in water, reaching a deep draft of more than 75 m. The assembly work of towers, nacelle, blades and transition pieces has already started in Norway for later installation on the Navantia-Windar foundations. The full set will be subsequently towed to Scotland for anchoring at its final emplacement offshore Peterhead in Scotland.

The fabrication contract, signed by Navantia-Windar in June 2015 has originated more than 450.000 working hours and has required important adjustments to the facilities and acquisition of machinery. Likewise, it has meant a great step for the consolidation of this joint venture in the offshore wind industry, and especially as a reference manufacturer of floating foundations.
