Entso-e systemKey Drivers for Transmission Investments and TYNDP

�Terna is involved as a member of ENTSO-E being the body of transmission system operators of electricity at European level.

�ENTSO-E's mission: to guarantee Security and Adequacy, improve Market competition and promote Sustainability


�Main European transmission projects are included in the TYNDP

�TYNDP was approved after six weeks of public consultation from 1 March till 11 April 2010

Entso-e system

Key Drivers for Transmission Investments and TYNDP

�over 42.000 km in next 10 years; the main technology

�European transmission investments driven by Security of Supply, Renewable Energy Sources, Market Integration

�TYNDP covers about 23-28 bn€ of about n. 500 transmission projects in next 5 years

�over 10 % in charge of Terna


�over 42.000 km in next 10 years; the main technology remains 400 kV HVAC OHL,

�other technical solutions are being implemented in specific situations (HVDC links, subsea cables, etc.)

Development of EU-MENA transmission systemsDevelopment of new interconnection on South – South axis

DESERTEC as “enabler”

coming before

development and

realization activity

Main transmission target:

� Identify grid requirements

for desert power


� Assess grid conditions

� Assess relevant

transmission technologies

� Work out optimal

transmission paths to

relax bottlenecks

� Develop transmission cost

model

� Develop scenarios for grid

arrangements

� Examine the impact of

transmission on EU/MENA


• MEDGRID foundation is a unique private industry joint venture aiming at creating a Trans-

Mediterranean grid system for transmission of energy between MENA countries and with Europe.

• Target of Medgrid:

� Design in partnership with

the MENA countries, the

Mediterranean transmission

Development of EU-MENA transmission systemsDevelopment of new interconnection on South – South axis


grid Master Plan for 2020

� Promote a regulatory and

institutional framework

� Assess the benefits of

investments in grid

infrastructures

� Develop technical and

technological cooperation

with the MENA countries

� Promote HVDC technologies

for power transmission

Growing interconnection around the

Mediterranean Area

�UCTE block expanded to Southeastern

Europe

�Interlinkage to SW-Mediterranean block

and recently also with Turkey on going

Technical challenges for the completion of the Mediterranean ring


Challenges for completion of Medring

remain

�failed synchronisation attempts with

SE-Mediterranean (Libya-Tunisia)

�Low capability of North African

Countries to react to disturbances

If synchronisation tests continue to fail,

linking the systems through HVDC may

be a possible option

HVDC

MENA-Europe maritime connections: Seabed morphology and depth pose limitations

Further evaluation:

�Assessment of feasible corridors in Mediterranen area

�Analysis of previous feasibility studies (results, status, involved parties)

�Preliminary identification of time line, costs and benefits of planned projects
