EU legislation on the security of gas supply requires that Member States with underground gas storage facilities ensure that their storages are at least 90 percent full ahead of the winter season between the period from 1 October to 1 December 2026. This requirement was introduced as part of the joint EU’s effort to strengthen energy security and was adopted in the wake of Russia’s invasion of Ukraine. In light of the war in the Middle East and the current difficult market situation, the European Commission has encouraged Member States to make appropriate use of the flexibilities provided in the regulation. As Denmark is a net exporter of gas, with domestic production from the Danish North Sea and significant biogas production, Denmark has decided to make use of this additional flexibility. Consequently, Denmark's national filling target has been reduced to 75 percent.
As of 10th September 2026, Denmark’s two gas storage facilities were approximately 78 percent full while around 83 percent of the storage capacity had been booked.
Procurement of Gas Storage Obligation
On behalf of the government, the Danish Energy Agency will repeat last year’s tender aimed at maintaining a high gas storage level ahead of the winter of 2026-2027. The tender will contribute to Denmark meeting its national storage filling target of 75 percent between 1 October and 1 December 2026.
The procurement of storage obligations is carried out as a tender within the dynamic purchasing system. The maximum value of the Procurement of Gas Storage Obligations will be 50.000.000 DKK for a minimum volume of 4.742.500 MWh gas. The procurement is carried out to incentivize market participants to agree to store a given volume of gas in the Danish gas storage facilities at 1st of November 2026. The procurement initiative supports compliance with EU legislation and strengthens Danish gas security of supply ahead of the winter season.
