Alstom Installing World’s Largest Offshore Wind Turbine off the Belgian Coast

LEVALLOIS-PERRET, France -- November 20, 2013

Regulatory News:

Alstom (Paris:ALO) has just completed this week-end the seaside installation
of its new-generation offshore wind turbine, the 6-MW Haliade™ 150, off Ostend
harbour at the Belwind site in Belgium. This is the largest offshore wind
turbine ever installed in sea waters. Thanks to its 150-metre rotor (with
blades stretching 73.50 metre), the turbine is more efficient since its yield
is 15% better than existing offshore turbines, enabling it to supply power to
the equivalent of about 5,000 households.

Following successful tests performed on the first Haliade 150 commissioned in
March 2012 at Le Carnet site in France, which successfully obtained in May
2013 the IEC (International Electrotechnical Commission) power performance
measurement (power curve^1), this installation will help in confirming how the
machine behaves within the offshore environment for which it was specifically
designed and developed.

The 61-metre jacket has been set on top of pillars which have been sunk to a
depth exceeding 60 metres. Then the 3 elements of the 78-metre tower were
gradually assembled on the jacket. In all, the nacelle towers at a height of
over 100 metres above sea level. The overall weight of the turbine and its
structure totals 1,500 tonnes.

This new-generation wind turbine operates without a gearbox (using direct
drive). Thanks to a permanent-magnet generator, there are less mechanical
parts inside the device, making it more reliable and thus helping to reduce
operating and maintenance costs. Lastly, the Haliade 150 features Alstom’s
PURE TORQUE^® design, which protects the generator by diverting unwanted
mechanical stress towards the tower, thereby optimising performance.

Now that it has installed this wind turbine in sea waters, Alstom has reached
an important milestone in the industrialisation process of its 6-MW turbine.
For its part, the Carnet wind turbine should be securing its final
certification during the first half of 2014. The construction of the two
factories in Saint-Nazaire (nacelles and generator) is well underway, and will
end around summer 2014. The construction of the two Cherbourg factories
(blades and towers) will follow.

“This project with Belwind asserts our technological leadership and our
innovative abilities. The installation of our turbine which is simple, robust
and efficient thus contributing in boosting the competitiveness of offshore
wind energy,” stated Alstom Wind Senior Vice-President  Alfonso Faubel.

“Belwind’s tried and tested expertise in completing offshore projects and
setting up wind farms has helped Alstom to perform the installation work in
sea waters under the best possible conditions. We are convinced that Alstom’s
innovative wind energy technology will contribute in providing one of the
future solutions to ensure clean, reliable and efficient energy,” said Belwind
chairman Wim Biesemans.
