Ultimate goal is providing a methodological background supporting the implementation

of the Energy Infrastructure Package of the European Commission Identification of technical performances, economic benefits and costs of novel tech-

nologies aimed at increasing capacity, reliability and flexibility of the transmission

infrastructure

Definition of long term scenarios for the European power sector, characterized by

different evolutions of demand and supply, such as the integration of a large amount

of intermittent RES

Implementation of a framework to facilitate harmonisation of pan-European ap-

proaches to electricity infrastructure evolution and to evaluate benefits of transmis-

sion investments

Short/mid term Long termShort/mid term Long termThis analysis has been specifically carried out in support of the creation of the Infrastructure package by EC (Interim Report).

1. Build-up new

infrastructure

2. Anticipate needs

in the planning

3. Speed up and

harmonize legal

procedures (top-

down)

4. Facilitate merchant

investment wherever

convenient5. Refurbish the existing

infrastructure

6. Reform the

electricity market

7. Act on public

opinion and on

compensation

policy (bottom-

up)

8. Boost TSO

investment optimality
