Vestas has installed its first 1.5 MW turbine at Tjærborg in the far west of Denmark. With a rotor span of 63 metres it is the country's largest wind turbine. The Tjærborg site also houses ELSAM's 2 MW turbine from 1988, Nordtank's 1.5 MW, installed in the autumn, and a 750 kW prototype from Bonus, still out of operation following its catastrophic failure last year. It is to be replaced by a new and modified version. The Vestas machine, expected to generate four million kilowatt hours a year, is owned by utility Vestkraft.
