Regulatory News:

Transmission System Operator TenneT has awarded the DolWin3 offshore project
to Alstom (Paris:ALO). This project connects the North Sea wind farms to the
mainland supergrid and has an investment volume of more than €1 billion. "With
this project, we help to take the energy turnaround another step forward and
make it possible for offshore wind energy to make an important contribution to
our future energy supplies", says Lex Hartman, member of the board of TenneT.
"With DolWin3 included, we will be able to supply a total of more than 6,000
MW of clean energy from the North Sea – and we will be investing more than €7
billion in the energy turnaround."

DolWin3 is the eighth grid connection project to be implemented by TenneT
using direct current technology. Together with three projects based on AC
current technology, the Transmission System Operator responsible for the North
Sea will then deliver a total of around 6.2 GW of offshore wind energy to the
mainland. The DolWin3 project will be the third grid connection in the DolWin
wind farm cluster in the south-western region of the North Sea and will offer
a capacity of 900 MW. The project will be completed in 2017.

“For DolWin3, TenneT will benefit from Alstom’s advanced technology. As market
leader for offshore AC substations and onshore HVDC, we are well positioned to
enter the German offshore HVDC market as a new competitor. The collaboration
with Nordic Yards and Prysmian, who both have outstanding references, is key
to delivering this turnkey contract,” says Grégoire Poux-Guillaume, President
of Alstom Grid.

As the general contractor for TenneT, Alstom will supply and construct both
the onshore and offshore converter stations as well as the connecting cable
systems for DolWin3. The project will use direct current technology (with
Voltage Source Converters (VSC); ±320 kV, 900 MW) to deliver the energy
generated at sea down an 83 km sea cable to the mainland. From the coast, the
wind power will then be transported a further 79 km via and underground cable
to the converter station in Dörpen/West in Lower Saxony (Germany). The grid
connection will be supplied as a turnkey solution by Alstom.

Together with the turnkey contract, Alstom has been awarded a five-year
service contract covering the complete offshore converter station and
platform, as well as the onshore converter system. The contract includes
inspection, preventive and corrective maintenance, refurbishment and repair,
spare parts management and a technology support line.

Alstom has chosen the most experienced partners on the market to complete this
project, working with platform constructor Nordic Yards and cable supplier
Prysmian. Both companies are highly experienced in the field of offshore work.
“One of the main challenges for the future of energy grids is to transport
electricity from offshore wind turbines to the onshore grid with as few losses
as possible. With DolWin3, we strengthen our position as a key partner in the
German energy turnaround”, says Alf Henryk Wulf, CEO of Alstom Germany.
