Natural gas storage revenue amounted to €401 million13, an increase of €29 million, equal to 7.8%, compared with 2011. The increase is essentially due to the contribution of investments made in 2010 (+€26 million) and the tariff updating mechanisms (+€3 million), whose effects were partly absorbed by the reduction in the volumes of gas moved (-€5 million). Storage revenue refers to modulation storage (€335 million; +10.6%) and strategic storage (€61 million; -7.6%).
EBIT totalled €270 million in 2012, up by €15 million, or 5.9%, compared with 2011. Increased storage revenues (+€26 million, net of revenues offset in costs) were partly offset by the increase in amortisation and depreciation (-€7 million), due mainly to the entry into service of new infrastructure, and by the increase in operating costs (-€2 million, net of components offset in revenues), due mainly to higher provisions for risks and charges.
