Snam aims at diversifying energy supply in order to ensure security of supply and greater flexibility of the system

Italy is however a country in which gas is still less economical than elsewhere in Northern Europe because the country, which until now has simply been a consumer market for the gas flows coming mainly from the North and the East, has been penalized by several factors. The increase in flows from the south, made possible by the evolution of infrastructure in progress, will position Italy as an energy hub capable of offsetting the reduction in production in the North Sea and the Central and Eastern European countries.

Snam’s strategic objectives are in line with the European ones:

  • Diversification of the gas supply by opening of new routes (supply from Azerbaijan through the Trans Adriatic Pipeline, exploitation of sources in the Eastern Mediterranean, new flows of LNG);
  • Development of the South-North and West-East energy corridors, by eliminating bottlenecks and increasing the linking capacity through reverse-flow;
  • Creation of a single European market, to facilitate the exchange of flows at a continental level.

On the South-North energy axis, Snam is helping to construct the bidirectional link between Italy and mainland Europe in collaboration with the Belgian operator Fluxys through the construction of reverse-flow capacities along the Trans Europa Naturgas Pipeline (Tenp)/Transitgas gas pipelines, which link Italy with Germany via Switzerland. In addition, Snam is also present (with a share of 31.5% in a joint venture with Fluxys) in Interconnector UK, the operator of the bidirectional pipeline linking the United Kingdom with mainland Europe.

Looking specifically at Italy, the main project along the South-North corridor concerns the construction of a link from Italy, via Switzerland, to France and Germany.

Snam’s growth is consolidating the European infrastructure system and fosters alignment between the interests of consumers and producers, promoting greater liquidity in the gas market.

At the end of 2015, Snam acquired a 20% share of the TAP consortium, the company that is constructing the Trans Adriatic Pipeline, a gas pipeline that will carry gas produced by the Shah Deniz II field in Azerbaijan through Turkey, Greece and Southern Italy.

On the West-East axis, through the acquisition of a share of 40.5% in French operator TIGF (now Teréga) in 2013, Snam controls an important energy junction positioned strategically along the route connecting France to the Iberian Peninsula. Through its holding in Teréga, Snam can help to integrate the Spanish market with the French market and, in perspective, those of other European countries positioned along the same West-East axis.

Snam also holds a large share (84.47%) in the Austrian gas pipeline TAG, through which the gas coming from Russia flows as far as the Italian border (Tarvisio). TAG represents the largest gas importation infrastructure for the Italian market and can potentially be used in reverse-flow towards Eastern Europe and Southern Germany.

Austria has also recently announced an agreement between OMV and a consortium made up of Allianz (60%) and Snam (40%), which will result in the latter acquiring 49% of Gas Connect Austria.


Further development of the gas market in Italy and its full integration with European markets will, according to forecasts, have a positive impact on energy prices, reducing costs for Italian companies and ensuring major savings for families.

The opening of new routes and the connection of Italy with strategic areas such as the Caspian Sea and Western Mediterranean areas would also have positive repercussions on the national electricity system, as about 40% of its production comes from gas. This would maximize the benefit obtained from the current modern group of plants.

Reverse flow

Snam invested significantly for the realization of the reverse flow, enhancing infrastructures in the Po Valley and along the Apennines.

Reverse Flow allows to reverse the gas flow into the pipelines. In this way the resource is able not only to enter but also to exit Italian gas transportation system. In 2018, Italy would have a physical capacity - in other words it would re-export natural gas - for 40 million cubic meters per day or 13 billion cubic meters annually. The capacity would be distributed between Passo Gries (towards Switzerland, Germany and France) and Tarvisio (towards Austria and Germany).

This infrastructure evolution will foster competition between sources of supply and will strengthen the role of the Peninsula as the gateway to natural gas directed towards Europe, resulting in further economic benefits for businesses and families.

In constructing and upgrading facilities, Snam operated in compliance with the most binding environmental standards, working closely with local and national bodies and institutions to protect the environment and local communities.
