Vacon delivers AC drives to hundreds of wind turbines

Vacon Plc, Stock Exchange Release, October 11, 2007 at 1 p.m.:
The AC drives manufacturer Vacon has made a significant contract with
The Switch, a Finland-based manufacturer of permanent magnet
generators and power converter packages that are used in wind
turbines. This contract strengthens Vacon's foothold in the
fast-growing wind power market."The wind power market is growing very fast due to climate change.
This significant contract with The Switch is so far our largest
delivery to wind power production. I am convinced that our strong
cooperation with The Switch will benefit both parties," says Mr
Heikki Hiltunen, Executive Vice President, Vacon."The Vacon AC drives we have now ordered will be delivered as a part
of our system to various customers to be installed into hundreds of
wind turbines globally," says Mr Jukka-Pekka Mäkinen, President and
CEO, The Switch. The Vacon AC drives will be built on liquid-cooling
technology, and they will be delivered during the year 2008.

The permanent magnet generators and power converters are today the
preferred solution in new wind turbine designs. When the Vacon AC
drive is used for the control of the permanent magnet generator, the
mechanical stress to the system is decreased, the power quality
requirements of electricity can be met and efficiency is improved.

The wind power market is today about EUR 15 billion, and it is
expected to double during the following two years. In 2006,
investments to various forms of renewable energy amounted to USD 45
billion. These investments increased the world's wind power capacity
by 13 gigawatts and solar energy capacity by 2.5 gigawatts.

The Switch solutions support the battle against climate change. They
transform untapped energy into electricity and contribute to its
efficient use. The company makes innovative power electronic systems
and drive-train concepts for OEM and system integrator customers.
