Terna: authorisation process launched for new underground power line in the province of Viterbo

TERNA: AUTHORISATION PROCESS LAUNCHED FOR NEW UNDERGROUND POWER LINE IN THE PROVINCE OF VITERBO

Work will involve installation of 9 km of underground cable

Approximately € 23 million investment to increase efficiency of the electricity transmission

system in the area

Rome, 6 February 2023 - Following launch by the Italian Ministry of the Environment and Energy Security of the authorisation procedure for a new power line in the province of Viterbo, Terna, the operator of the national transmission grid, has published the plots of land potentially affected by the work.

The project, for which the company led by Stefano Donnarumma will invest € 23 million, involves creation of a 150 kV underground-cable power line running for 9 km, connecting the primary cabins of Viterbo and Pian di Tortora, both in the Municipality of Viterbo.

The work will enable improved meshing of the local grid and an increase in efficiency and reliability of the electricity transmission service, guaranteeing greater continuity and security of operations.

The connection, which will run primarily along existing roads, will be created using latest-generation cables with XLPE insulation. This is particularly reliable and sustainable technology that guarantees greater transport capacity for the integration of renewable generation plants in the areas.

Once authorisation is received from MASE, the new connection will go live within 24 months.

It will be possible to view the project documentation at the Italian Ministry of the Environment and Energy Security, the Lazio Regional Authority and the Municipality of Viterbo, and citizens may submit written observations to the Ministry and to Terna within 30 days of publication.

Terna, which has approximately 2,000 professionals working daily on the development and maintenance of the regional electricity grid, manages over 4,400 km of high and extra-high-voltage power lines and 53 substations in Lazio.
