Context

European Commission - Strategic Energy Technology plan targets by 2020:

• 20 % reduction of GHG emissions (when compared to 1990 levels)

• 20 % of renewable energy in the EU energy consumption (2005: EU 8.5 %; 2005: IT 5.2%, 17% in 2020)

• 20 % reduction of energy consumption (baseline 1990, 13 % compared to 2006)

in compliance with the EU energy policy:

reliability, sustainability, market efficiency


Uso: pubblico

Smart Grids are high on the European energy agenda…

� Electricity Grids is one of the six industrial initiatives proposed by the EU in the European Strategic Energy Technology Plan (SET-Plan)

� The Smart Grid European Technology Platform, has just concluded its work with a Strategic Deployment Document

� The EU ask for concrete proposals to set up a European Industrial Initiatives (EIIs) on Smart Grids.

� Several European Projects on going on Smart Grids related topics, e.g.:

Address, Susplan, Fenix

Uso: pubblico

DSOs InitiativeObjectives

� To define a concrete framework of a common research

and demonstration program to foster the development of

smart grids.

� To identify the medium and long term investments

necessary to the development of a European

integrated Smart Grid infrastructure

� To highlight shared action plans covering the main pillars

of this development.


Uso: pubblico

The expected benefits from the program

1. Improved peak consumption management

2. More efficient use of energy and further reduction of carbon emissions from the electricity industry.

3. Pave the way to the advent of electric vehicles

4. Start reducing the future investment and operational costs of the EU electricity distribution grids

5. Bring industrial benefits to European manufacturers by:

� Mitigating engineering and business deployment risks

� Converging towards European technology standards

� Validating the technology scalability and replication
