The National Electricity Transmission Grid Development Plan

 

Operation and objectives of the Terna Development Plan.

The National Development Plan defines the transmission grid needs based on:

  • current and future trends in electricity demand to be covered;
  • need to consolidate the grid;
  • requests to connect new power generation plants to the grid.

The main elements that characterize the 2019 National Development Plan are:

  • The transition to an energy system centred on renewable energy sources
  • The improving of the resilience of electrical system enabling it to handle the new extreme weather events
  • The attention towards territory, intended as both its geographical and human
  • Technological and methodological innovation as well as a well-structured development of the network to ensure the integration of renewables and system security

The document illustrates all the new measures taken for the development of the National Transmission Grid planned to reach these objectives. The information provided every year through the Development Plan is supplemented by the “Status Report on previous Development Plans”, which describes the status of actions and works to be started, pending authorization or under construction for the construction or upgrading of power stations, the construction of power lines to connect new power plants, the elimination of grid congestion, and the boosting of interconnection with foreign countries.

The Grid Development Plan at the European Community/ENTSO-E level

 

EC Regulation no. 714/09 grants ENTSO-E, the European Network of Transmission System Operators, the tasks of adopting and publishing, every two years, a non-binding ten-year network development plan (TYNDP) for the European Union, which includes integrated grid models, the development of scenarios and forecasts on the adequacy of supply and demand at the European level.

Also in regards to ENTSO-E, the regulation foresees that grid managers establish regional cooperation to contribute, among other things, to the adoption of investment plans on a regional basis.

The Development Plan is based on national investment plans, and includes regionally-based investment plans, taking the entire EU into account to plan European infrastructure. The grid development plan at the EU level also identifies investment requirements in regards to cross-border capacity and possible obstacles that may arise, for example due to authorisation procedures.

ACER, the Agency for the Cooperation of Energy Regulators, issues an opinion on the Development Plan for the ENTSO-E grid, to assess how well national development plans align with the plan at the EU level. The grid development plan at the EU level is also involved in a consulting process with ENTSO-E.

Following the consultation process, ENTSO-E adopts and publishes the Ten-Year European Network Development Plan, pursuant to article 8 of EC Regulation no. 714/2009.

In 2018, ENTSO-E published the Ten Year Development Plan 2018
