DOING BUSINESS
A new High Voltage Direct Current system
will interconnect Italy and France along a
190km land route between the substations
of Piossasco, near Turin in Italy, and
Grand’Ile in Savoy, France, with a total of
approximately 95km in each country.
Prysmian Group will lead the consortium
of
seven
companies
that
secured
the
project
awarded
by
Terna
Rete
Italia
and
RTE,
the
transmission
system operators in Italy and France.
Prysmian to lead the execution of the record-setting power connection worth more than €500 million.
Strategic link between Italy and France
The total value of the project is estimated
at more than €500 million. The share of
Prysmian, in its capacity as consortium
leader that will coordinate the design,
supply, installation and related civil works
and commissioning of the interconnection
is around €200 million.
The Group is also in the ±nal stages of the
HVDC interconnection between France
and Spain, that is starting operations in
mid 2015.
The boring machine, the second largest in
the world, will excavate a new undersea
two-level tunnel designed for use by light
vehicles only, such as cars and minibuses.
The project is a true milestone in Turkey,
running undersea between Europe and
Asia. Ground was ±rst broken for its
construction in 2011 and the machine
used for its excavation is powered by
special Tunnel²ex TX cable, produced at
Prysmian Group’s plant in Merlino, Italy.
The contract was awarded by Yapı Merkezi
İnşaat ve Sanayi A.Ş. and SK Engineering &
Construction Co. Ltd.
Powering undersea
tunnel machine in
Istanbul
The project, also known as the ‘Piemonte-
Savoia’ interconnection, will play a strategic
role in increasing the security of power
supply and enabling energy exchange
between Italy and France up to 1,200MW,
in a new and important step towards
the creation of a single European energy
market. Commissioning is scheduled for
2019. The overall length of the link is the
longest of its type and sets a world record
for HVDC underground interconnections
using extruded cable technology.
Prysmian Group is contributing
again to a major infrastructure
project in Turkey: power-feeding
the boring machine for the 14.6km
Avrasya Tunnel in Istanbul with
a new special cable.
