Common Questions

What is EU gas storage at right now in 2026?: AGSI+ data showed EU gas storage at 28.92% on 9 April 2026, the lowest for that date since 2018. Germany was the worst performer at 23.32%.Source: GIE AGSI+
How do I read the GIE AGSI+ dashboard?: AGSI+ shows working gas volume as a percentage of total storage capacity, updated daily for each EU member state and aggregated for the whole EU.
What is the EU gas storage target for winter 2026?: The European Commission reduced the mandatory storage target from 90% to 80% for the 2026 season, citing low starting levels and refill cost pressures.Source: European Commission
What is AGSI+ and who publishes it?: AGSI+ (Aggregated Gas Storage Inventory) is a daily-updated dashboard published by Gas Infrastructure Europe (GIE), the Brussels trade association for EU gas infrastructure operators. It is the primary public source for EU-wide gas storage fill rates, cited by the European Commission, ACER, traders, and media.Source: GIE
How full is EU gas storage in 2026 and is it on track for winter?: EU aggregate storage reached 37.0% by 22 May 2026, gaining at 0.17 pp/day — roughly a third of the 0.53 pp/day required to hit the European Commission's revised 80% target by 1 November 2026.Source: event
Which EU countries have the lowest gas storage levels?: The Netherlands hit 8.95% in late April 2026 — the lowest of any major EU storage market. Germany reached 27.2% on 5 May and is tracking toward approximately 52% by November on the current injection pace, well short of the 80% target.Source: event
What is the difference between AGSI+ and ALSI?: AGSI+ (Aggregated Gas Storage Inventory) tracks underground gas storage fill rates. ALSI (Aggregated LNG Storage Inventory) tracks LNG terminal inventory and sendout. Both are published by Gas Infrastructure Europe (GIE) and together cover EU gas supply-side infrastructure.Source: GIE

Background

GIE's AGSI+ dashboard is the primary public source for EU gas storage fill rates. EU storage reached a record low of 28.92% on 9 April 2026. By 22 May 2026, fill reached 37.0% gaining at 0.17 pp/day — barely a third of the 0.53 pp/day required to hit 80% by 1 November. Germany's sub-storage is tracked at 27.2% (5 May), projecting to 52% by November — well short of target. The Netherlands hit 8.95% in late April — the lowest of any major EU storage market.

How the World Sees Them

Germany

Germany's 27.2% fill on 5 May and its negative spark spread (gas-fired injection commercially unviable at EUR 47/MWh TTF) means the country is not injecting at the pace AGSI+ requires of it for the EU aggregate to hit target.

EU Commission

AGSI+ is the authoritative data source for storage obligation decisions; the 28.92% reading in April directly prompted the target cut to 80%.

Energy traders

AGSI+ fill-rate moves are immediate inputs to TTF and NBP futures pricing; a below-trend injection week triggers spread widening in winter delivery contracts.

Germany (BNetzA)

German storage at 23.32% on 12 April was the EU's worst deficit; BNetzA publishes separate national data but AGSI+ provides the comparative European frame.

European Commission

AGSI+ is the Commission's real-time storage tracking instrument; GIE data directly informs emergency supply security declarations and the 80% November storage target enforcement mechanism.
