Hywind Demo was placed in the sea west of Karmøy in 2009, and the construction cost close to NOK 400 million, of which 59 million were contributions from Enova. The price of the wind turbine is confidential, but the entrepreneur and owner of Unitech, Bernt Hellesø, calls it reasonable and reasonable, writes Teknisk Ukeblad .
Wind turbine construction weighs a total of 5,300 tonnes, and the turbine has a capacity of 2.3 megawatts which can supply 400 households annually with electricity. With the purchase, Unitech will, among other things, have the opportunity to test new high-voltage cables.
– In addition, the cable that is now located between the Hywind mill and the landfall at Sandve in Karmøy will have the capacity for increased power production. Thus, we will invite several actors who can test other types of floating offshore wind turbines and other technology. We want to facilitate this area to the benefit of several actors who want to develop technology within renewable energy production at sea, says Hellesø.
He expects Hywind to produce electricity for at least ten years. Unitech also plans to build a base for compiling Hywind floating offshore wind turbines in Tømmervika at Stord. This is where the Hywind Demo will eventually be dismantled.
