Lines and local communities

The construction of new lines responds to the technical needs of the electricity system – such as removing congestion and eliminating overload risks – and to increase energy production and consumption, which accompanies the economic growth of specific areas, or of the entire country. Terna includes necessary new construction in the Grid Development Plan, which every year follows a complex authorization procedure (for the authorization procedure of each specific project see the monitoring platform “Terna's Construction Sites for Italy” available on the website If grid development caters to society's general interests, the environmental impact associated with the construction of new power lines is instead concentrated in the local area affected by the route of the line. In addition, the population density of many parts of Italy and the value of the art, culture and landscape of many others make planning more complex and construction more difficult. In response to these problems, Terna has voluntarily adopted an approach that includes dialogue and consultation with Institutions to seek solutions that make it possible to preserve the richness and potential of the country's environmental and cultural assets.

The need to intervene on existing lines is usually due to the fact that many lines were built some decades ago. The gradual transformation of rural areas into urban settlements and the adoption of new legal rules, modifying parameters previously in force regarding the interaction between power lines and the territory, determine the need to make changes to portions of the existing grid.
