Storage system compensate different needs of supply and consumption of gas engendered by seasonality of demand. Snam manages nine storage facilities (Brugherio, Bordolano, Cortemaggiore, Treste Treste, Minerbio, Ripalta, Sabbioncello, Sergnano and Settala), which operates in synergy with the transport and regasification infrastructures of the Company, ensuring energy security of the Country.

The natural gas storage activity compensate different needs between supply and gas consumption. Supply - consisting of imports from overseas and domestic production - has a substantially constant profile throughout the year, while demand for gas is characterized by significant seasonal variability. For example, winter demand is significantly higher than the summer one. As a consequence, natural gas storage plays a primary role for the gas system.

Bordolano

The Bordolano plant operates from 2016: it is a jewel of efficiency, technology, safety and environmental sustainability that contributes to making the Italian storage system even safer.

Natural gas storage is a specialized process, where Snam operates according to strict safety and environmental sustainability criteria.

Stogit storage fields are depleted gas production reservoirs, located at average depths of between 1,000 and 1,500 metres below the surface. Having protected natural gas for centuries, these conformations are in fact suitable for containing new gas that is injected by our technicians.

Injection phase is concentrated between April and October, from November to March gas is withdrawn, processed and returned to shippers through the transport network.

The key element is the gas cushion, defined as the minimum amount of gas that must be present in the reservoir to allow the dispensing of the working gas - present in the storage phase - and counteract the rise of the aquifer without impairing the mining characteristics of the Field.
