Italy Unveils 2025-2034 Grid Development Plan
Terna, Italy's leading transmission system operator, has unveiled its comprehensive 2025-2034 Development Plan. This strategic blueprint outlines a substantial investment, marking a 10% increase from the previous plan. The initiative is designed to accelerate Italy's energy transition, enhance grid resilience, and integrate renewable energy sources more effectively.
Key HVDC Projects
- Tyrrhenian Link: This project involves a 500 kV HVDC submarine cable connecting Sicily, Campania, and Sardinia. Construction began in January 2025, with an expected operational date by 2028. The Tyrrhenian Link is pivotal in enhancing grid efficiency and facilitating the integration of renewable energy across Italy's southern regions.
- Adriatic Link: This connection will bridge Abruzzo and Marche, featuring a 1,000 MW capacity and 250 km in length, with 210 km being submarine. Its entry into operation is planned for 2029. The Adriatic Link will significantly improve energy exchange between Italy's central regions.
- ELMED Interconnection: The Italy-Tunisia (ELMED) link is another key project, aimed at strengthening connections with North Africa and consolidating Italy's role as a Mediterranean energy hub. This interconnection will enhance cross-border energy exchange and support regional energy security.
- SA.CO.I. 3: This project involves connecting Sardinia, Corsica, and Tuscany with a 200 kV direct current electrical link. Work has already begun, with an expected operational date by 2029. The SA.CO.I. 3 project will improve energy security and sustainability across the region.
Critical Reinforcements and Future Developments
In addition to these major projects, Terna's plan includes critical reinforcements across Italy's transmission network. These efforts are designed to optimize grid efficiency, enhance resilience, and support the integration of renewable energy sources. Future developments will focus on:
- Additional HVDC Corridors: Terna plans to develop new HVDC corridors to further enhance grid capacity and facilitate the transmission of renewable energy across different regions.
- New Interconnections with European Countries: Projects like the double connection with Greece will strengthen Italy's position as a key energy hub in Europe, facilitating energy exchange and supporting regional energy security.
- Grid Optimizations: Terna will continue to invest in digitalization and innovation, leveraging technologies such as artificial intelligence and robotics to ensure a more connected, smart, and secure grid.
Impact on HVDC Industry
Terna's Development Plan highlights the growing importance of HVDC technology in modernizing power grids. The emphasis on HVDC projects supports Italy's energy transition and aligns with broader European objectives for decarbonization and grid resilience. As the HVDC industry continues to evolve, Terna's investments will play a crucial role in demonstrating the feasibility and efficiency of HVDC solutions for large-scale renewable integration and international energy exchange.
Environmental and Economic Benefits
The plan is expected to reduce CO2 emissions significantly. Economically, the investments will create opportunities for growth in the energy sector, supporting Italy's transition towards a more sustainable and interconnected energy system.
In conclusion, Terna's 2025 Development Plan holds HVDC technology at its core. As the industry continues to innovate and expand, Terna's strategic investments will be closely watched for their impact on the future of HVDC applications in Europe and beyond.
