The Swedish utility Vattenfall is to construct a 3 MWe wind turbine, believed to be the biggest in Sweden. The rotor blades will have a 90 m diameter.
The turbine, Olsvenne 2, is expected to produce 8 GWh of electricity per year. It will be erected on the island of Götland at a cost of 25 million krøner as a pilot project, but Vattenfall says that future projects would more likely be offshore wind parks.
The unit will help Vattenfall meet its anticipated green obligations. Sweden will introduce green certificates from 1 May, 2003, with mandatory quotas for suppliers rising each year by about 1 per cent, until it reaches 16 per cent in 2010, to meet the 10 TWh per year target. Producers will receive the certificates for renewable power generation which can then be sold as a financial instrument and bought by suppliers to fill mandatory annual quotas for green electricity.
