Eneco Luchterduinen – Q10

The 129MW Eneco Luchterduinen wind farm is located 23km off the coast between Zandvoort and Noordwijk cities in the Netherlands. The offshore project was developed by a 50/50 joint venture between the Dutch energy company Eneco and Japan’s Mitsubishi Corporation. IMG_4647

The wind farm occupies a 25km² area off the Dutch coast at water depths ranging between 18m and 24m. Onshore cable construction work for the project began in October 2013. The first wind turbine at Eneco Luchterduinen was installed in April 2015 and first power was generated in May. All turbines were installed by June and the wind farm was officially opened in September 2015.

The Eneco Luchterduinen wind farm generates clean electricity for nearly 150,000 houses. It consists of 43 Vestas V112 turbines of 3MW capacity each. The substations boost voltage from 33kV to 150kV and the export cable delivers the power to the national power grid.

Gemini

The 600MW Gemini offshore wind farm, which is  in the Dutch part of the North Sea, approximately 85km off the coast of Groningen, is one of the world’s biggest offshore wind farms. Northland Power, Siemens, HCV and Van Oord own the farm, while Northland Power is the operator.
It  produces approximately 2.6TWh of clean and renewable electricity, which can be used by approximately 785,000 households. It can offset 1.25 million tonnes of carbon dioxide emissions a year.20150829_182538

The project is built at two locations, Buitengaats and Zee-energie, and has a total surface area of 68km². The water depth ranges between 28m and 36m. There are 150 Siemens SW4.0-130 turbines, with a rotor diameter of 130m and blade length of 65m.

The 33kV electricity generated by the wind turbines is transferred to two offshore substations via a network of cables. It is then converted into a 220kV alternating current and is transported to the onshore transformer station in Eemshaven by two 120km-long export cables.

The 220kV AC power section is stepped up to a high-voltage current of 380kV and is transported to Oude Schild, via cables, before transmitting to the national power grid.

Sandbank

The Sandbank offshore wind farm is located 90km west of the island of Sylt in an exclusive economic zone off the German North Sea coast. It is being developed by a joint venture of Vattenfall and Stadtwerke München and is being built in 25m to 37m-deep waters. The new wind farm will have a gross installed capacity of 288MW and produce up to 1.4TWh per year, which would be enough to power approximately 400,000 households and cut down carbon emissions by 1.5 million tonnes a year20160604_074221

Vattenfall will own 51% and invest SWK5.6bn ($818m) in the project, which is estimated to cost SWK11bn ($1.6bn). Construction began on the wind farm in June 2015 and commissioning will be achieved in 2017.

The offshore wind farm is being installed with 72 Siemens SWT-4.0-130 turbines rated 4MW each and having a blade length of 63m. The inter array cables have a voltage level of 33kV and the two export cables are connected in Sylwin Apha at a voltage level of 155kV

Merkur

Merkur is a construction-ready wind farm located in the German exclusive economic zone approximately 45km north of the islands of Borkum. In early 2015, DEME Concessions Wind took over the development of the project from former developer Windreich and was joined by GE later that year.  Construction will be under a dual contract structure with GE as supplier of 66 GE Haliade 150-6 megawatt wind turbine generators and GeoSea as turnkey contractor for the entire balance of plant. Offshore foundations installation is expected to commence in August 2017, with project completion scheduled for March 2019.

Deutsche Bucht

Northland Power Inc’s 269-MW wind project in the German North Sea. Dutch offshore contractor Van Oord NV is acting as an engineering, procurement, construction and installation (EPCI) balance of plant contractor for the scheme. The Deutsche Bucht wind park will be located off the island of Borkum in the German Exclusive Economic Zone. It will use 31 units of MHI Vestas Offshore Wind’s V164 8.0 MW wind turbines, totalling 252 MW, installed on steel monopile foundations.
