## Concentrating Capital on Critical National Interconnections

Following regulatory approvals from Peruvian authorities, Terna finalized the disposal of concession assets spanning over 500 km of high-voltage transmission circuits in central and southern Peru. The transaction marks the final step in Terna’s strategic pivot to divest non-core Latin American concessions.

The released financial resources will be deployed to accelerate Italy’s domestic grid upgrades, primarily the €3.7 billion Tyrrhenian Link (a 1,000 MW, 500 kV HVDC subsea link connecting Sicily, Sardinia, and the Italian peninsula) and the €1.3 billion Adriatic Link (1,000 MW, 400 kV HVDC link between Abruzzo and Marche).

## Converter Station Progress and Cable Manufacturing

Civil works for the converter substations at Fiumetorto (Sicily) and Terrauzza (Campania) have achieved advanced construction milestones, preparing foundation slabs for the 500 kV converter transformers and modular multilevel converter (MMC) valve halls.

Simultaneously, subsea cable manufacturing across Prysmian and Nexans facilities is running ahead of schedule, utilizing mass-impregnated and cross-linked polyethylene insulation rated for depths exceeding 2,150 meters in the Tyrrhenian trench.

## Launching Joint MARI Platform Balancing Trials

Concurrently on September 28, Terna and market operator GME initiated market integration tests for the European MARI (Manually Activated Reserves Initiative) platform, modernizing cross-border balancing reserve exchange across southern and central Europe.

Terna confirmed that dedicating 99% of capital expenditure to national infrastructure directly enhances European energy security and enables seamless assimilation of over 40 GW of upcoming renewable projects.
