Supported bythe European Union

Webinar “Towards a Mediterranean Sustainable Energy Future”

Med-TSO: multilateral cooperation in the Mediterranean

A bridge between Europe and the MENA Region, acting as THE reference regional stakeholder for electricity

Playing a regional reference role for creating a favorable climate for the development of North-South and South-South

interconnections

Launching pilot projects to strengthen the integration of the MENA Power Systems

Support the EC in its Euro-Mediterranean initiatives

Bottom-up approach

21 members from 19 Med countries

> 500 million people served

~ 544.000 MW installed capacity

~ 400.000 km transmission lines

> 1600 TWh electricity consumption


Energy transition in the Mediterranean context

Integration is no longer an

option

TSOs called to adapt to this new context

• System operation more complex due to fast and massive growth of RES

• Needs for more system flexibility

Integration as key driver for energy transition

Complementarities:

i. seasonal (North/South)

& hourly (East/West)

ii. structural differences in

the generation mix

Additional challenges

• Limited interconnections or non efficient use of the existing ones

• unstable environment for investors: market fragmentation, lack of long-term price signals

All countries involved in the energy transition

• Growth of demand

• Need of investments in gas & RES, often limited by market fragmentation & heavy asymmetries in RES legislation and regulation

Reinforced cooperationis essential

Inadequate interconnection

Masterplan projects assessment framework

The Mediterranean Network development

Plan (Masterplan) includes:

1. Definition of Mediterranean scenarios

2. Definition of the list of future

interconnection projects

3. Set up of reference models of power

system at regional level to perform

market studies

4. Analysis of the network behavior (load flow calculations) and of the investments needed to fulfil the

security requirements

5. Perform a shared Cost-Benefit Analysis (CBA) for the new investments


Med-TSO 2030 Reference scenarios development

• Explore possible future situations of load

and generation, interacting with the

Mediterranean Power system

• Wide contrasts and complementarity in

terms of load growth and of RES

development

• Contrasts in the evolution of demand

• Contrast in national energy and

environmental policies

• Contrasts in the organization of electricity

exchanges between countries

Common technical parameters and principles, to ensure the coherency on market studies:

• Efficient day-ahead markets or mechanisms

• Similar fossil fuel prices across all Mediterranean countries

• Economic value for CO2 emissions common to all Mediterranean countries


RES & Electricity evolution at 2030

HERE

PICTURE

Electricity consumption expected to

increase by 25 to 33% by 2030

Power generation shows a consolidating

trend towards increased RES,

decreased fossils, and uncertainty on

nuclear.

Wind offshore: has been considered,

although, despite recent announcements

(Turkey, Italy, Morocco) there are not

many initiatives yet in the Mediterranean

sea


2030 Marginal price differentials & CO2 reduction

Source Med-TSO «Mediterranean Project 2»

The average marginal

price (€/MWh) results

from the competitiveness

of the national generation

fleets and the supply-

demand balance.

Same trend in the three

scenarios


CBA methodology is developed to evaluate the benefits and costs of

new interconnection projects from a Mediterranean perspective,

providing important input for the assessment of the interconnection

projects considered in the Mediterranean Region. The main objective

of this CBA methodology is to provide a common and uniform basis

for the assessment of these projects

Modelling of thermal units, seasonal hydro reservoirs, storage systems, and intermittent generation

Construction of Monte-Carlo scenarios embeddingseveral possible hourly timeseries of electrical demand,intermittent wind and solargeneration, hydraulicinflows and availability ofthermal units

Mediterranean Evolution

scenario and a consistent

decrease in overall CO2

emissions

Start the preparation of coordinated national

Network Development Plans

Start implementing a coherent and harmonized

set of Technical Rules for managing the

existing interconnections

Promote the effective Operation of the

interconnected power systems, also through the

use of a Web based platform


TEASIMED – Coordinated adequacy assessment

• Does the country ‘A’ have enough capacity to cover

power demand even under severe/extreme conditions?

• How could the interconnection reduce shortage

situations?


TEASIMED – Knowledge Sharing programme

• Knowledge Sharing → workshops with the key stakeholders

• Launch of common trainings → explore with Florence School of Regulation or other institutions the

possibility to organize a dedicated mini-training course for Med-TSO’s members on relevant topic
