Winter 2025-2026: Teréga has completed its auction campaign for gas storage

Teréga's storage represents 26% of French capacity. The two underground reservoirs at Lussagnet (Landes) and Izaute (Gers) help to ensure the country's security of energy supply, and their geographical position gives them a major role at the crossroads of South European gas exchanges.

34,000 GWh of storage capacity subscribed

Teréga's storage capacity for 2025-26 was sold from November 2021 to 25 March 2025, following auctions organised on its Storeplace platform. During these auctions, 4 different storage products were offered to the market in order to meet all needs:

• FIZZ (withdrawal in 85 days): 22,200 GWh ;

• FAIR (withdrawal in 110 days): 9,300 GWh ;

• FAST (withdrawal in 40 days): 1,600 GWh ;

• OPSTOCK (withdrawal in 55 days): 900 GWh.

Of the 45 companies that took part in the auctions, 38 are now customers for the 2025-26 storage year (+2 compared with last year).
