New 1,000 mw Italy-Switzerland connection line: Terna investment of 1.2 billion

In the 2021 Development Plan, Terna planned a new 1000 MW power connection line between Italy and Switzerland, whose construction is linked to the project for the rationalization of the high voltage grid in Valtellina and Valchiavenna (in the province of Sondrio) which will lead to the demolition of almost 500 km of existing power lines and the burying of overhead lines. For this important intervention, Terna has planned an investment of over 1.2 billion euros. This is what emerges from Terna’s new 2021 Development Plan which was illustrated today by CEO Stefano Donnarumma. In Terna’s 2021 Development Plan, in addition to the new 1000 MW connection line between Italy and Switzerland, the group led by Stefano Donnarumma will invest around 750 million euros for the construction of a new submarine cable with Greece of 500 MW of power and 200 km of length. The project will double the current exchange capacity between the two countries and encourage greater integration of renewable sources. The Sa.Co.I.3 project, the reconstruction of the connection between Sardinia-Corsica-Italy, has been confirmed in the 2021 Development Plan. interconnections, together with the power lines between Italy-France, Italy-Tunisia and Italy-Austria, will allow our country, by virtue of its strategic geographical position, to strengthen the role of electricity hub in Europe and the Mediterranean area, becoming a leading player in international level.
