Italy’s grid operator earmarks €23 billion for renewables integration

ROME, March 14, 2025 – Italy’s state-controlled grid operator Terna will invest more than EUR 23 billion over the next 10 years to facilitate the integration of renewable sources and increase the transport capacity of the national grid, the company announced on the release of its 2025 development plan on Friday.

Italy’s national energy plan calls for the addition of more than 65 GW of installed solar and wind capacity by 2030 and 94 GW by 2035, both relative to 2023. Terna’s investments will be aimed at developing enabling infrastructure, resolving local congestion, streamlining new connections to the grid and reinforcing cross-border interconnection.

 

In particular, Terna will seek to boost international transfer capacity by 40% over current levels and increase the capacity for energy exchange between markets to around 39 GW from the current 16 GW.

“Investing in the modernisation of electricity grids is essential to cope with the growing demand for energy and the integration of renewable sources. Requests for the connection of renewable plants, storage systems and data centres are increasing, and to help Italy remain an attractive prospect for investors we have adopted a new process for our infrastructure to enable the connection of new resources efficiently,” said Giuseppina Di Foggia, Terna’s CEO and general manager.

Terna noted that most of the planned grid interventions will take advantage of existing infrastructure and will be capital-light, and are expected to be operational by 2030. The operator further noted that the interventions should bring emissions reductions of up to 2 million tonnes per year (tpy) of carbon dioxide by 2030, and 12 million tpy by 2040.
