Royal Decree-Law 25/2026 increases GNL storage requirements to ensure supply during winter cold snaps or gas shortages, raising the obligation from 16.5 to 21 days for the November-March period (art. 1). It also establishes temporary price caps on commercial bottled LPG in containers between 8 and 20 kg (art. 1). These measures address energy market instability caused by the Middle East conflict.
For entities required to store gas, operational and inventory burdens will increase as mandatory reserves rise from 16.5 to 21 days, although a 15% tolerance margin is permitted for daily compliance provided the monthly average is met (Art. 1). Butane consumers in rural or vulnerable areas will benefit from a cap on maximum selling prices for 8 to 20 kg canisters (Art. 1). The energy sector must adjust its winter action plans to comply with the new thresholds for November-December 2026 and March 2027 (Art. 1).
