The Switch now offers widest range of permanent magnet packages available for wind power

VANTAA, FINLAND, Jul 06 (MARKET WIRE) --

By adding several new models to its offering, The Switch, a Finnish-based
technology company, is the first company to provide a complete portfolio
of permanent magnet based generator packages specifically designed for
maximized wind power generation. The latest additions include an outer
rotor generator, a modern-style 2.5 MW drive train, and a double-fed
option.

VANTAA, FINLAND - July 6, 2009 - The Switch, a provider of megawatt-class
permanent magnet generator and full-power converter packages for wind
power and other new energy applications, now offers the most complete
range of PM packages.

Outer rotor generator - launch of a new platform for easy turbine
integration

The introduction of the newest generator model combines the benefits of a
permanent magnet (PM) and direct-drive solution with an outer rotor.
These PM machines represent the technology of choice for next-generation
wind power generators, as they offer a platform of highly integrated
components that are built to last and require very little maintenance.

The simple, straightforward design integrates the main shaft, main
bearings, gearbox and mechanical brake into a single generator "combo".
The outer rotor reduces the weight of a direct-drive application. The
generator shares a common bearing with the turbine itself, and the
turbine's brake system has been integrated as part of the generator. The
gain is realized in simplicity, fewer components - and therefore, higher
reliability.

"For newcomers to modern technology in the wind power industry, The
Switch outer rotor generator offers an ideal solution, because it's the
fast-track way to make a high-performance turbine," says Jukka-Pekka
Maekinen, President and CEO of The Switch. "Our new outer rotor permanent
magnet technology enables the best possible energy yield in varying wind
conditions, thereby maximizing annual energy production."

"As the industry shifts toward PM technology, The Switch is already able
to offer second generation products," Maekinen continues. "Our large
direct-driven machines have been successfully operating since 2005, a
relatively long time in modern wind power history."

The Switch outer rotor prototypes are currently being shipped to Chinese
Dongfang Electrical Machinery Co., Ltd. (DFEM), a leading supplier of
cutting-edge wind power technology in the Chinese market. The generator's
cast-iron body facilitates high volume production. The first orders of
the outer rotor generator will be installed in the mountainous region of
Mongolia where they will operate in extreme conditions and at very low
temperatures.

2.5 MW redesign - more energy from existing turbine

Another new offering is the redesigned 2.5 MW drive train for
conventional turbines. This PM generator and full-power converter package
has been planned for manufacturers who aim to upgrade their existing wind
turbine offerings without making substantial changes to their proven
designs.

"This modern-style 2.5 MW drive train is based on a growing market need
to take greater advantage of existing turbine technology, but allowing it
to do more with the wind available. In other words, to maximize the
amount of power to energy - which fits perfectly with our business
mission," Maekinen explains.

Double-fed option with modular power packages

As many wind power turbine manufacturers have selected double-fed
induction generator (DFIG) technology, originally due to lower costs and
preference, The Switch now offers 1.5 MW and 2 MW packages specifically
designed for these manufactures to help them tap into higher power
ratings. The Switch double-fed option comes with modular power conversion
packages and well-matched generators for exceptional flexibility.

"The Switch is now well-known for its pioneering efforts to establish
permanent magnet solutions as the preferred choice in the industry," says
Reijo Takala, Vice President, Wind Power. "Yet, we've realized that
turbine manufactures that apply double-fed technology, too, are searching
for ways to improve output performance and take greater advantage of
conditions with limited wind speed variations. The Switch now can serve
these manufacturers with flexible converter and generator solutions and
high component reliability. We have been able to bring our know-how in
world-class wind solutions to deliver successfully to those who want to
stay with the double-fed approach."
