THE POWER OF THE WIND

The wind: a key factor in world economy Wind needs clean, renewable and competitive sources of energy; wind is a very competitive alternative to energy from fossil fuels.

RESPECT FOR THE ENVIRONMENT

THE VESTAS VISION Vestas is the world leader in wind technology. Its core business regards the development, manufacture, sale, marketing, and maintainance of installations that use wind energy to generate electricity.

Life cycle assessment of the wind turbine

OptiTip ® OptiSlip ® OptiSpeed ® What are them?

OptiTip® A microprocessor- controlled pith regulation system which ensures continuous and optimal adjustment of the angles of the blades in relation to the prevailing wind.

OptiSlip® A generator system that allows both the rotor and the generator to vary their speed by up to 10% during wind gusts, maximising power quality and reducing the strain on turbine components.

OptiSpeed® A further development of the OptiSlip® system. OptiSpeed® allows the speed of revolution of both the rotor and the generator to vary by up to approximately 60 per cent and optimises energy production, especially in modest winds. The turbine starts to generate power to the grid already at 4 m/s.

The OptiTip® and OptiSpeed® systems make it possible to optimise the solution to the often contradictory requirements for high output and low sound levels.

What types of turbines does Vestas manufacture? Vestas began wind turbine manufacturing in 1979 and has played an active role in the dynamic wind turbine industry ever since.

Where are the turbines manufactured? The manufacturing of wind turbines based on Vestas Technology takes place at 12 different locations i Denmark, two in Germany, one in Italy, one in Scotland, one in Tasmania (Australia), one in India, two in Spain, one in Norway, two in Sweden and one in England.

How many wind turbines has Vestas erected? Since 1999, Vestas has experienced a notable increase in MW sales, from 653 MW in 1999 to 1,812 MW in The tendency is for the erection of fewer but more productive turbines. This means that from 2001 to 2002 and from 2002 to 2003, the company actually erected fewer turbines, but those erected have greater capacity.

Over the past five years, Vestas has erected the following: Sales in number of turbines Sales in MW 1999:843 turbines653 MW 2000:1,014 turbines805 MW 2001:1,970 turbines1,645 MW 2002:1,453 turbines1,640 MW 20031,369 turbines1,812 MW

At what wind speeds can Vestas wind turbines generate power? Vestas wind turbines typically start to generate power at wind speeds of around 4 m/s and normally cut out when wind speeds reach 25 m/s.

What does a wind turbine cost? The price of wind turbines depends on many parameters, for example the turbine type, the foundation type, the location of the site, and transportation. Therefore, it is not possible to give a general price on Vestas wind turbines.
