Grid development

in the generation and consumption of electricity. Both supply and demand of electricity grow at different rates in different areas of Italy. The combination of these elements changes the flows of electricity in the system, causing congestion on the existing grid.

To meet these needs, every year Terna prepares grid development investment programmes, so as to stay up to date with the evolution of production capacity and consumption, and to increase its efficiency and security. The development work that Terna plans and carries out also has positive repercussions on society: in fact the assumption underlying its implementation is that the collective economic benefit that this work generates is higher than its cost.

Every year Terna prepares a Transmission Grid Development Plan (DP) containing the national transmission grid development projects envisaged for the next 10 years and the progress status of development works planned in past years.

The 2013 Development Plan is concerned with the transmission grid development investments falling within the 2013-2022 period. This year, the 2013 Plan is made up of a core document with three appendices of more detailed information. In particular:

  • the 2013 Development Plan constitutes the central document which describes the framework of reference, the targets and criteria into which the transmission grid planning process is divided in the national and European context, the forecast scenarios and new development needs which emerged during 2012, the action priorities and expected results deriving from implementation of the Development Plan itself;
  • Appendix 1 - Details of evolution of the legislative framework of reference contains details of recent legislative and regulatory measures in the industry;
  • Appendix 2 - Main aspects of the electricity system and markets describes the main phenomena and trends that have characterized the national electricity system in recent years;
  • Appendix 3 - Technical and economic assessments provides further information on the economic sustainability analysis of the main development projects.

The 2013 Development Plan is available on Terna's institutional website in the section devoted to the Electricity System. Approved by Terna's Board of Directors with a resolution on December 19, 2012, it was sent for assessment for the purposes of approval to the Ministry of Economic Development and to the Electricity and Gas Authority on January 29, 2013, and subsequently to the competent Institutions involved.

For feedback on stakeholders' main expectations, the 2013 Plan was also submitted for assessment to the Grid Users' Consultation Committee (see the paragraph on Stakeholder Involvement), which expressed a favourable opinion both on the new development projects and on the 2013 Plan as a whole.
