Snam: 10-year plan for development of the Italian gas network

In the 2025–2034 National Gas Network Development Plan, Snam and Terna used the BID3 and Pegasus models by AFRY to simulate and optimize both the electricity and gas markets. BID3 enabled them to analyze the Italian electricity market’s evolution, while Pegasus provided deep insights into gas flows, LNG utilization, storage, and price dynamics across Europe.

Aims of the study

The Ten-Year Development Plan sets out Snam’s vision for a secure, sustainable, and flexible gas infrastructure that supports Europe’s energy transition. It responds to global challenges—geopolitical tensions, decarbonisation targets, and digitalisation—by ensuring resilience and competitiveness. The plan aims to strengthen Italy’s role as a strategic energy hub, reduce dependency on single supply sources, and enable integration of renewable gases and hydrogen into the national system.

 

Use of BID3 and Pegasus

To underpin its strategy with robust analysis, Snam employed both BID3 and Pegasus modelling tools. There were used to simulate market dynamics, infrastructure scenarios, and system flexibility under varying conditions. By using these tools, Snam checked investment priorities, optimised network expansion, and assessed the impact of renewable integration and hydrogen corridors on long-term security and sustainability.

 

Key findings

The study confirms that targeted investments—over €17.9 billion by 2034—will deliver a 16% increase in transport capacity, accelerate decarbonisation, and enhance supply security. Major projects include the Adriatic Line, new LNG terminal connections, and the first hydrogen-ready pipelines. Electrification of compressors and biomethane integration will cut emissions significantly, while the development of CO₂ transport networks positions Italy at the forefront of the low-carbon economy. These initiatives collectively ensure a resilient infrastructure capable of meeting Europe’s net-zero ambitions.
