Regulatory News :

Alstom (Paris:ALO) has completed the acquisition of Tidal Generation Limited
(TGL) from Rolls-Royce plc. In September 2012, Alstom announced that it had
agreed to acquire TGL, which specialises in the design and manufacturing of
tidal stream turbines, subject to the achievement of critical milestones
including the successful installation of the 1 MW tidal turbine at the
European Marine Energy Centre’s (EMEC) full-scale tidal test site in Orkney,
Scotland.

On 24^th January 2013, TGL, now rebranded Alstom successfully installed the
1MW tidal turbine on the same tripod support structure used to deploy the
previously tested 500kW device.

As part of the Energy Technologies Institute (ETI) commissioned and co-funded
ReDAPT (Reliable Data Acquisition Platform for Tidal) consortium project, the
1MW tidal turbine will be tested in different operational conditions off
Orkney over an 18 month period. Detailed environmental information and real
life sea performance data will be generated in order to further improve tidal
power technology and to reach a commercial scale. The next step is to install
pilot arrays prior to full commercial production.

“The UK is a world-leader in the development of renewable energy technologies.
Together, Alstom, the ETI and the ReDAPT partners are accelerating the
development of tidal technology helping to position it, as a new more
affordable, secure and sustainable source of energy.” said Dr David Clarke,
Chief Executive Officer, Energy Technologies Institute.

“This new milestone installation in the development of tidal power generation
technology is a step further towards the commercialisation of this new power
solution. The aim of this project is also to demonstrate a new, efficient and
reliable turbine design” said Jacques Jamart, Senior Vice President Alstom New
Energies.

With a rotor diameter of 18m, a twenty-two metres long nacelle and a weight of
150 tonnes, the tidal turbine has three pitchable blades. Buoyancy enables the
turbine nacelle to be easily towed to and from the point of operation. This
minimises installation and maintenance costs by avoiding the need for
specialist vessels and divers and reduces the timeframe to install or retrieve
the turbine. The unit operates, fully submerged at a water depth of 40 meters,
by rotating to face the incoming tide at an optimal angle, to extract the
maximum energy potential.

“This technology will optimise electricity production, limit maintenance
constraints, and thus will help reduce the cost of electricity of this
renewable energy source” said Jérôme Pécresse, President of Alstom Renewable
Power. With the integration of new resources, skills and know-how, we will be
ready to respond to the first tenders for the development of tidal arrays in
France and in the UK, with the best range of products available in the market”

With this acquisition, Alstom continues to develop the broadest portfolio in
the renewable power industry. The company offers the most complete range of
products and integrated systems, for hydro, onshore and offshore wind,
geothermal, biomass and solar power.
