tion is negligible and priority is given to domestic consumers. 3. Security issues: lessons from the recent past The Italian gas system has significant experience of critical and unexpected situations. Two exceptional events have taken place in recent years: the interruption of the Greenstream flow due to the outbreak of the conflict in Libya at the end of February 2011, and the 6-month shutdown of the Transitgas pipeline (which connects Italy to Northern Europe), from July to December 2010, because of a landslide in Switzerland. In the attempt of realizing a crisis infrastructural equipment, which can face the interruption of a pipeline or the consequences of an exceptional cold snap, storage infrastructures stand as key-asset for the system. In the current system, those facilities play a crucial role in satisfying consumption modulation, because they ensure the flexibility required for the execution of administration contracts to the selling companies. Good storage capacity has also been proven to be a basic precondition for the creation of a liquid market, both in the gas and electricity sector, increasing arbitrage opportunities among markets in different countries. Such liquidity is currently not a feature of the Italian system, that cannot rely on satisfying networks neither at the internal nor at the European. To further illustrate this point, it is useful to consider a spe- cific case: the emergency situation that arose in February 2012. On February 1 st 2012, Gazprom did not appear to be able to meet the increased supply demand its European clients. In the Italian context, this imbalance was reflected in a discrepancy between requirements and transits of 12.3% at the entry point of Tarvisio. The gap increased up to 24.2% the following day, and up to 30% by February 3 rd . Despite the geopolitical tensions arising from polarised views of Ukraine’s alleged violation of the gas agreements - having withdrawn more gas than its contract allowed for - the main factor in the 2012 crisis was simply the cold snap which struck Europe, Turkey and indeed Russia itself. The withdrawing of stored volumes has thus covered, once again, 6 the Russian shortage. Friday 3 rd February, 32 mcm were withdrawn from storage, in order to meet an unusual high demand: 414.7 mcm daily. The following week, due to the extreme cold and intense industrial activity, the demand did not shrink, reaching record highs on February 6 th and February 7 th . Consumption on February 7 th was 465.9 mcm, setting an absolute record of network intakes. A comparison with the comparable Tuesday in 2011 illustrates the exceptional nature of this peak (Figure 2). As a result, gas withdrawals in the industrial sector in 2010 were heav- 85 CASPIAN REPORT, SPRING 2014 6. Similar extraordinary condition where met in 2005 and 2009.
