offshore wind farm

Siemens Gamesa Renewable Energy today held a launch ceremony with local government authorities and wind industry partners in Taiwan for what will be the company’s first offshore nacelle assembly facility outside of Europe. Construction is due to begin in 2020 at the site located in the port of Taichung. This represents an important milestone for the company in the fast-growing Asia-Pacific region. Siemens Gamesa currently has offshore nacelle assembly and manufacturing facilities in Germany and Denmark.

The parcel of land being developed in Taiwan measures over 30,000 square meters, and will be used for nacelle assembly, testing, warehousing, office buildings, and outdoor storage. Siemens Gamesa is also working closely with Taiwan International Ports Corporation (TIPC) to establish inbound and outbound logistics in newly-established quaysides nearby.

Construction is planned to begin in 2020, and production in 2021. The facility will then support Ørsted’s 900 MW Greater Changhua 1 & 2a project, for which the SG 8.0-167 DD turbine will be used. In later years, it will provide an option for the supply of nacelles to other regional projects.

“Thanks to this nacelle assembly facility, we will be creating more opportunities of working with the growing localized supplier network as well as developing a skilled offshore workforce. All these efforts will contribute to building a competitive local supply chain, in line with international standards in terms of safety, costs, quality, and making Taiwan a leading offshore market,” says Niels Steenberg, General Manager of Siemens Gamesa Offshore for Asia-Pacific.

The long-term collaboration between SGRE and TIPC was first officialized in December 2017 via a Memorandum of Understanding. Both parties agreed to cooperate towards developing Taichung harbor for the offshore wind power industry.

In 2016, Siemens Gamesa erected Taiwan’s first two offshore turbines composing the 8 MW Formosa 1 Phase 1 project. The company is currently installing the subsequent phase, the 120 MW Formosa 1 Phase 2 project. This is Taiwan’s first commercial-scale offshore wind power project, and features 20 SWT-6.0-154 wind turbines. Siemens Gamesa has signed contracts in Asia Pacific for close to 2 GW of offshore wind power projects for the years to come, including 1.5 GW of confirmed orders.

Iberdrola has entered into an agreement with Green Investment Group (GIG), part of the Macquarie group, to sell a 40% share in East Anglia One (EAO), the offshore wind project that the company is building in the British North Sea. This will bring a new shareholder into the project, of which Iberdrola will maintain a 60% majority shareholding.

According to transaction terms and conditions the entire value of EAO amounts to £4.1 billion and when the wind farm is operational in 2020, Iberdrola will receive £1.63 billion (about €1.75 billion [1]) for the 40% stake. These funds will be allocated to the Group’s organic growth plans referred to in the 2018-2022 Strategic Plan.

The completion of the transaction is subject to the standard authorisation from the Crown Estate.

EAO is the largest renewable project ever undertaken by a Spanish company. Once commissioned in 2020, it will be one of the world’s largest wind farms, with an installed capacity of 714 MW, supplying 600,000 British homes with clean energy.

Iberdrola, steadfast commitment to offshore wind power

Over the next few years offshore wind will be an investment focus for Iberdrola, developing a project portfolio of over 10,000 MW. This growth focuses on three main areas: the North Sea, the Baltic Sea and the United States.

Clean power generated by offshore wind farms is a cornerstone of the company’s strategy, which expects to allocate 39% of the €34 billion earmarked for the 2018-2022 period to renewable energy: €13.26 billion.

The group is currently operating two offshore wind farms: West of Duddon Sands, which went into service in the Irish Sea in 2014, and Wikinger, in the German waters of the Baltic Sea, which has been operational since December 2017.

Iberdrola is in the process of building the biggest offshore wind farm in the United States: Vineyard Wind. Just off the coast of Massachusetts, it will produce 800 MW of power to cover the energy needs of a million homes.

In Germany, in April, the company was awarded contracts to build two new plants in the Baltic Sea, which will produce a total of 486 MW: Baltic Eagle and Wikinger Süd.

In addition to these new plants, the Sant Brieuc wind farm, which is located in French waters, is scheduled to be commissioned in 2022. It will have 496 MW of installed power and will be located just off the coast of French Brittany, 20 kilometres offshore.

Once these projects are operating in late 2022, the company will have installed 2,000 MW of offshore wind power, after which it will add a further 1,000 MW.

Iberdrola is committed to growing its renewable energy business. Globally countries have ambitious objectives for new wind generation facilities. The UK is seeking to develop 30,000 MW of offshore wind, and the United States is developing 25,000 MW.

The first offshore wind farm one hundred per cent designed and operated by a Spanish company

Iberdrola has officially cut the ribbon on Wikinger offshore wind farm, one of the company’s most iconic power plants in the world, having invested over €1.4 billion. Wikinger is fully operational and its 350 MW are connected to the German grid, supplying efficient renewable energy to 350,000 homes (representing some 20% of the energy demand of the state of Mecklenburg-Vorpommern). This flow of clean energy will have a positive environmental impact since it displaces the emission of nearly 600,000 tons of CO2 per year.

The Wikinger project marks Iberdrola’s entry into the German electricity market, where it has just been awarded the construction of two other offshore wind farms: Baltic Eagle (476 MW) and Wikinger Süd (10 MW). Together with Wikinger, these three wind farms, located off the island of Rügen, will give rise
to the largest offshore wind complex in the Baltic Sea, with a total installed capacity of 836 MW and a combined investment of €2.5 billion.

Wikinger is the first offshore wind farm to be designed and operated one hundred per cent by a Spanish company. It has consolidated Iberdrola as Europe’s leading company in renewable energy, capable of developing projects in markets as competitive as Germany and meeting the demanding planning conditions set by German authorities. In addition, it has served to boost the entire supply chain, benefiting companies across Europe, including Navantia and Windar.

This project has come to fruition thanks to the multidisciplinary and multinational composition of the team set up by Iberdrola and its network of first-rate international suppliers and contractors. Over 2,000 employees from 20 different countries participated in this milestone project. Iberdrola has had to overcome the technological challenges inherent to this type of work and the difficulties arising from the extreme weather conditions in the Baltic Sea.

Wikinger, a mark for Iberdrola

Located off the north-east coast of the German island of Rügen, Wikinger brings together the main themes of Iberdrola’s strategy: strong investment in the development of renewable energies, commitment to reducing emissions, technological innovation, international growth, opening of new markets and business lines to its suppliers, and an important boost for the European naval industry.

To build the project, 280 piles were installed. Measuring 40 metres in length by 2.5 m in diameter, and a unit weight of 150 t, they were all built by Spanish company Windar. A total of 70 foundations were laid on them, each weighing 620 t, manufactured by Bladt Industries in Lindo (Denmark) and Navantia, at its shipyard in Fene (Spain).

The 5-MW Siemens Gamesa AD 5-135 wind turbines were manufactured in the company’s plants in Bremerhaven and Stade (Germany). These are the wind turbines with the highest power rating and largest dimensions that Iberdrola has installed thus far. With a total height of 165 m, they are made up of a 75-m high tower, a 222-t nacelle and a 135-m diameter rotor, with each blade measuring 67 m long.

Finally, one of Wikinger’s key pieces of infrastructure is the Andalucía offshore substation, which will be used jointly by Iberdrola and 50Hertz, an electricity system operator in Germany. Weighing around 8,500 tonnes, the energy heart of the wind farm was also built by Navantia in Puerto Real in southern Spain.

Commitment to offshore wind power

Offshore wind energy is one of the keys to Iberdrola’s growth and the company has undertaken notable projects in this sector in the United Kingdom, Germany and France. These large investments will help advance the transition to a decarbonised energy model and combat climate change. These are the main projects underway:

West of Duddon Sands (WoDS): Located in the Irish Sea, WoDS was the first offshore wind farm the Iberdrola Group was involved in. It was developed by the company in consortium with Orsted and came into operation in 2014. It has 389 MW capacity and the investment was over £1.6 billion.

East Anglia One (EAO): Mega-project currently under construction in British waters in the North Sea, it will become one of the world’s largest offshore wind farms when it starts operating in 2020. It will involve an estimated investment of £2.5 billion and have a capacity of 714 MW.

Saint-Brieuc: This 496-MW facility will be located 20 km off the coast of Brittany in northern France, about 100 kilometres from the city of Rennes. It will have 62 Siemens-Gamesa turbines, with 8 MW unit capacity.

Vineyard Wind: Iberdrola, through Vineyard Wind, recently received authorisation from the Massachusetts Electric Distribution Companies (EDC) to construct a wind farm off the north-east coast of the United States. The project, which represents the company’s first large-scale offshore wind farm venture in that country will have 800 MW capacity.

ABB has been selected to deliver its pioneering WindSTAR transformers specifically designed for floating wind turbines, to MHI Vestas Offshore Wind. The transformers will be installed in each of the three wind turbines on WindFloat Atlantic, a floating, offshore wind farm, comprising the world’s largest and most powerful wind turbines ever installed on a floating foundation. The 8.4 MW wind turbines are 190 m tall to blade tip, more than double the height of the Statue of Liberty. Just three of these turbines will provide enough electricity for over 18,000 households in Portugal. The WindFloat Atlantic windfarm will come into operation in 2019.

Floating wind farms comprise wind turbines mounted on floating structures that allow the turbines to
generate electricity in water depths where fixed-foundation turbines are not feasible. Floating wind
farms have the potential to significantly increase the sea area available for offshore wind farms, especially in countries with limited shallow waters.

The WindFloat Atlantic windfarm will be positioned 20 km off the coast of Viana de Castelo, Portugal, in a location where the sea is 100 m deep. Traditional offshore wind turbines are secured onto the seabed and can only be used in depths of approximately 40-50 m. This floating solution opens up large regions of previously unusable ocean to renewable offshore wind power generation.

ABB will supply its WindSTAR power transformers that are specifically engineered to be extra resilient
against strong vibrations and extreme and sudden movements encountered on floating wind farms. The
compact transformers are all designed to fit into the tower of offshore turbines. These 66 kV transformers for floating applications, present an important opportunity to facilitate offshore wind farms installed in deeper water. Traditional wind turbines are not viable in deeper waters and require expensive and difficult-to-install subsea infrastructure. The 66 kV voltage level is the highest wind turbine rating in the industry, allowing for significant reduction in transfer losses and enabling higher efficiency.

Framo’s pump technology has been used to successfully anchor 20 wind turbines at the offshore wind farm Burkum Riffgrund 2.

A total of 60 suction buckets have been pumped in place as foundation for the 20 offshore wind turbines in Ørsted’s new wind farm Borkum Riffgrund 2. In June 2018, a team of specialists from Framo, the Norwegian Geotechnical Institute (NGI) and GeoSea installed the first of the 20 suction bucket jackets at the offshore wind farm. After periods of storm and high waves, the foundations of all 20 wind turbines were safely pumped into the seabed with the final jacket foundation installed on Monday, 30 July. The full commissioning of the wind farm is planned for early 2019.

The suction bucket jacket technology for offshore wind farms has gone from concept to reality during the last five years. Besides lowering costs due to the increased installation speeds compared

to traditionally piled jackets, the concept provides for easier decommissioning and practically noise free installation.

This is the first time Framo’s technology has been used to pump so many wind turbines in the same wind farm and is quite unique that so many wind turbines are anchored with suction anchors in one field.

Framo is a sub-contractor to NGI in the installation of the 20 offshore wind turbines. NGI and Framo have collaborated on the installation of offshore anchoring and foundation elements using suction/vacuum since the 1990s.The technology of suction and bucket foundation has been used to secure and safely anchor platforms and offshore installations around the world. Now larger wind farms are being built with this technology. The foundation is installed by pumping water out of the buckets. This creates a suction/vacuum, which press the buckets into the seabed.

The windfarm Borkum Riffgrund 2 is located 54 km off the coast of Lower Saxony, in the German North Sea. In the installation of the 56 wind turbines, 20 will use the suction bucket technology as foundation and 36 will be supported using monopiles. The three-legged foundations measure more than 50 m in height and weighing 950 t each.

ABB has won orders worth over $150 million from Danish energy company, Ørsted (previously Dong Energy), to supply a range of technologies that will help integrate and transmit renewable wind energy from Hornsea Project Two, slated to be the world’s largest offshore wind farm. The orders were booked in the second quarter of 2018 and are the first tranche of a global five year frame agreement for the supply of electrical and automation equipment for offshore and onshore wind power connection and integration to the grid.

Hornsea Two is a 1,400 MW project to develop wind resources in the North Sea about 100 kilometers off the Yorkshire coast. Upon completion, it will be able to deliver enough clean electrical power to meet the needs of more than 1.3 million homes annually. The additional power supply will support economic growth in the UK’s Humber region, and help the UK meet its target of generating 15 percent of energy needs from renewable sources by 2020.

abb_svcABB will supply its state-of-the-art Static Var Compensation (SVC) Light technology with advanced ABB Ability™ MACH control systems, High Voltage gas-insulated switchgear (GIS), transformers, reactors and harmonic filters. ABB will also be responsible for the engineering, supply, project management and commissioning of the digital control and protection systems for the onshore substation and the two offshore platform substations.

The electrical power flow from Hornsea Two farm will be protected and controlled by the largest Static Compensation (STATCOM) system ever built for an offshore wind application. STATCOMs help offshore wind generating turbines to increase power transfer capability, improve power quality and enhance grid stability, delivering energy efficient and reliable power supply. The brain of the STATCOM is the ABB Ability MACH control, protection and monitoring system, managing this sophisticated technology by overseeing thousands of operations in real time to ensure power reliability and efficiency.

As part of the project scope, the ABB Ability™ enabled MicroSCADA system will be used for monitoring of the electricity network and gather data from Relion® Intelligent Electronic Devices (IEDs) and Remote Terminal Units (RTUs) to ensure safe and reliable grid integration system operations. Advanced mission critical technology will also be used for communication between the offshore platforms and the onshore substation.

It will be installed at the world’s largest offshore wind farm currently being built

Iberdrola and Navantia has marked the delivery of the offshore substation, christened as Andalucia II, entirely built at the shipyard of Puerto Real (Spain) and destined to Iberdrola’s East Anglia One offshore wind farm in the United Kingdom. Andalucía II, the largest AC offshore substation ever to be fabricated, will set sail over the next few weeks and will be installed at the site of Iberdrola’s offshore wind farm. With 714 MW total capacity and an investment of £2.5 billion, East Anglia One is the world’s largest renewable energy facility being built by a Spanish company.

Present at the event were José Esteban García Vilasánchez, Chairman of Navantia, Ignacio Galán, Chairman of Iberdrola and Susana Díaz, Head of Analusia’s regional government who christened the substation.

East Anglia One, a driver of job creation and economic development

East Anglia One offshore wind farm has become a key driver of economic development in all of the areas taking part in the manufacturing of the equipment and installation activities. As was the case with Wikinger, now operating in the Baltic Sea, Iberdrola awarded Navantia, together with some 30 specialised ancillary companies, the fabrication of a key element of the wind farm, its offshore substation.

After 16 months of work, the unit has been delivered according to schedule and has enabled the creation of approximately 450, mainly local, jobs, reaching 600 on peak working periods.

Innovation at the largest AC offshore substation

Andalucía II offshore substation is at the heart of the wind farm Iberdrola is building in British waters. Its role will be to collect the electricity generated by the wind turbines and transform the supply voltage from 66kV to 220 kV. Power will then be carried by the export cable to land, thus minimising losses along the route.

The topside, the world’s largest AC substation, includes design innovations developed by Iberdrola to make it more compact, bringing down is weight to 3,900 tonnes while facilitating handling by installation vessels.

In early August, the Andalucía II substation will be towed from Puerto Real to British waters with arrival scheduled for early September. Over the next few months, piles, jackets and topside will be installed on site alongside the rest of the WTG jackets.

East Anglia One will be commissioned in 2020 and will produce enough clean energy to power the consumption of nearly 600,000 UK homes.

Having pioneered the development of onshore wind, Iberdrola is leading the way of the renewable energy source with the largest growth prospects: offshore wind.

The company currently operates two offshore wind farms, West of Duddon Sands in the Irish Sea, and Wikinger, in the Baltic Sea and has a project pipeline of over 7,200 MW in the North Sea, Baltic Sea, French waters and the Northeastern US coast.

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.
