Electricity will play a more and more
important role to meet the three main
objectives of the European Energy Policy


To increase the security of supply;



To reduce CO
2
emissions;



To control energy costs.

On the demand side, electricity provides high level
energy efficiency ;


On the supply side, it provides for the development
of low carbon energy sources (from nuclear,
hydraulic, wind, solar, geothermal).

2/3 of the production from low carbon sources;



1/3 nuclear;



1/3 renewable sources (including hydraulic)


of which 13 % wind energy (1.9% in 2005).

13% wind energy in the electricity mix in 2020
implies a production of 500

out of a total of 4 000
TWh

a

quantity,

200

250

out

of

Looking ahead to 2050


When CO
2
capture and sequestration (CCS)
technology is industrially available, it will be
possible to design a European power system
with nearly no CO
2
emissions.

SUCH A RADICAL CHANGE IN THE MIX OF POWER
GENERATION WILL REQUIRE A GREAT EVOLUTION
OF THE GRIDS.

Why such a change ?


To allow for the large integration of intermittent renewable
energies ;



To increase the security of supply by mutual back up
between the power systems of the Member States of the
EU and with the neighbouring interconnected regions;



To reach a wider integration of the electricity markets.


10

Montenegrin NC of CIGRE Session

19 of May 2011

What does this mean for the future of the
grids ?


Stonger interconnections within the European system ;



An
extension

of these interconnections beyond the
present limits (to the South around and across the
Mediterranean Sea and with the Russian electricity
system UPS/IPS) ;



A more efficient operation of the electricity systems and
particularly the distribution networks to face the growing
complexity of systems management.

Smart Grids

:


Distribution Networks



The
opening

of
electricity

markets

has
led

to the
development

of the smart
meter

which

is

the
cornerstone

of Smart
Grids

in the distribution network.


The
European

Commission
targets

80% of smart
meters

in 2020*.



The network
is

changing

from

passive to active
through

the
development

of
decentralized

power
generation

from

wind

or
solar

installations and
its

structure
and
operation

must
be

quickly

adapted
.
