The German electricity grid already enjoys the connection of the Wikinger offshore wind farm, which has been built over the last year and a half in German waters of the Baltic Sea.
This project has involved an investment of about 1.400 million euros. The park has 70 wind turbines, provides 350 megawatts of net power, capable of supplying renewable energy to about 350.000 homes.
In Park will avoid the emission into the atmosphere of almost 600.000 tons of CO2 per year, and can contribute over 20% of the state where it is located (Mecklenburg-Western Pomerania).
The park itself is located off the northeast coast of the German island of Rügen. The company has a command, control and maintenance center in the port of Sassnitz.
Construction
The boat has been used to build the park Brave Term, of the Fred Olsen shipping company. It is a rare ship: it has four huge holed steel columns that look like chimneys and an even bigger crane in the middle of them.
These columns have the peculiarity that, once the ship is on the high seas, a mechanism makes them penetrate to the bottom of the sea and become four paws on which the ship rests so that the crane can maneuver and fix the wind turbines on the platforms that are planted in the middle of the Baltic Sea. It has a cost of 200.000 euros per day.
280 piles measuring 40 meters in length and weighing 150 tons, built by the Asturian company Windar, have been installed on the seabed. The 70 foundations in which support wind turbines, of 620 tons each, have been manufactured by the Danish company Bladt, in its shipyard in Lindo (Denmark), and by the Spanish Navantia, in the shipyard in Fene (La Coruña). The contract with Navantia amounted to 160 million euros.
The turbines have been manufactured by the Adwen company in its plants in Bremerhaven and Stade (Germany), each one has 5 MW of power. One of the key infrastructures of the park, the substation marina «Andalucía», has been built by Navantia at its facilities in Puerto Real (Cádiz).
The installation, which weighs 8.500 tons (more than the Eiffel Tower and the Statue of Liberty together), it is the energy center of the park and will be used jointly by Iberdrola and 50 Hertz, operator of the German electricity system.
The mills are connected to each other and to the Andalusia substation through 12 cable circuits. The complex, which is a close investment at 1.400 million euros, it will have a power of 350 megawatts (MW), at five per wind turbine. Iberdrola, which will operate the park for 25 years, expects a turnover of 220 million a year.
Iberdrola
Iberdrola has decidedly committed to offshore wind energy as one of the keys to the future of the company. The countries chosen to carry out their activity in this New business They are, for the moment, the United Kingdom, Germany, France and the United States.
wods
The company reached a milestone in 2014, by becoming the first Spanish company to start up a wind farm, the West of Duddon Sands (WoDS). Iberdrola developed this project through its British subsidiary ScottishPower Renewables and in a consortium with the Danish company Dong, investing more than 1.600 million pounds between them. WoDS has a power of 389 MW, which allows it to produce electrical power enough to meet the demand of approximately 300.000 British households.
East Anglia One
Likewise, Iberdrola is preparing to begin this year the construction of its third offshore project, the East Anglia One wind farm, with a capacity of 714 MW that will supply clean energy to more than 500.000 English households, the largest Spanish project in history in the world. renewables sector and the largest offshore wind farm in the World when it goes online in 2020 after an investment of 2.500 billion pounds. Siemens will be in charge of supplying 102 turbines of 7 MW of unit capacity for this marine park, which will be built by the German manufacturer in its new facilities located in the town of Hull, in the northeast of England.
In addition, Iberdrola has requested the British Government expand this facility up to 2.000 MW. To this end, it has presented to the UK authorities a proposal to build the East Anglia Three wind farm, which would have 1.200 MW of power.
