Our development and innovation pathway to decarbonising the energy system
With the implementation of the investments envisaged in the Development Plan, we will significantly reduce CO2 emissions and make the Italian electricity system more resilient and sustainable.
Terna's activities are in line with the SDGs, especially Goal 7 ("Affordable and clean energy"), Goal 9 ("Industry, innovation and infrastructure") and Goal 13 ("Climate action").
Strengthen resilience and adaptive capacity to climate-related risks and natural disasters
Their achievement includes interventions in three main areas:
Energy production from renewable sources represents a potential increase in energy thanks especially to the increase in wind and photovoltaic plants in the southern and island regions of Italy.
One of Terna’s main tasks is to plan the strengthening of the grid and promote the production of electricity from renewable sources. Terna must also attempt to overcome possible grid and operational constraints that risk the feed-in of this energy into the grid, in the context this energy’s priority status in dispatching.
Grid losses are primarily dependant on two factors:
Date came into operation: 29 September 2017
Date came into operation: 27 June 2017
The geography of energy is a fundamentally important aspect to guarantee high-level efficiency over the entire production and distribution system:
there are electricity areas with the potential to produce energy more efficiently compared with areas where power stations are obsolete and polluting.
The development of the electricity grid therefore aims to promote production from the first by relieving the load from the second, thus improving the entire system’s production mix.
The interventions envisaged in the Development Plan are directed at improving the production by increasing interconnection capacity on foreign electricity borders.
This will provide for a decrease in energy procurement costs and increased market integration, with the consequent increase in resources available to manage the Italian and European electricity system.
190 km of lines completely underground
25 municipalities crossed (in the province of Turin)
This project is a global first in terms of the engineering, technological and environmental solutions applied: this will become the longest underground electricity line in the world, with a very low impact on the environment and territory.
The most significant benefits that this will have for the electricity markets in Italy and France refer to reduced congestion between the two countries and increased and more efficient use of renewable sources.
445 km of power lines with undersea and underground cables
1,200 metres – depth below sea level where the cables will be laid
1,200 MW infrastructure direct current power
This is a strategic project at European level, representing a significant opportunity for the Italian electricity system in terms of developing interconnection and integrating the entire Balkans area with Europe.
Its characteristic technical and engineering solutions aim to significantly minimise the environmental impact.
The high-voltage Prati di Vizze (IT) - Steinach (AT) interconnection line envisages exploiting the existing Prati di Vizze - Brennero power line.
The line will make it possible to significantly increase the electricity exchange capacity between Italy and Austria promoting market integration, the utilisation of production from renewable sources and service security. It will also provide significant benefits in terms of reducing the price differentials between Italy and Austria.
