Security of supply: From Tuesday November 1st, the capacity expansion of the Artère de l'Adour interconnection will be available to increase flows from Spain to France

This figure is equivalent to an 18% increase in the total flow capacity from Spain to France between the two existing interconnections, Irún and Larrau, which add up to a maximum total capacity of around 8.5 bcm per year .

The Spanish and French Transmission System operators (TSOs) Enagás and Teréga will increase the capacity available for contracting of the gas pipeline linking Bilbao to Lussagnet from 60 GWh per day to 100 GWh per day, in order to offer an additional alternative for supplying the territory.

This increase in South-North flow capacity should make it possible to transport more gas from the Iberian Peninsula if the market needs it. Indeed, it has infrastructures, in particular LNG terminals, that are surplus to its consumption needs.

Both Enagás and Teréga's infrastructure is already ready to carry out this significant increase in capacity which will strengthen the European gas network for the passage of winter.
