The print
GIE's AGSI+ feed places Swedish working-gas inventory at 9.9% of working volume, the lowest in the EU table this morning. The next three slots are Netherlands 13.3%, Belgium 20.8%, Bulgaria 22.6%.
What Swedish storage actually is
Sweden has roughly 1 TWh of working gas storage — a rounding error in the EU's 1,100 TWh total. The country's annual gas consumption is about 10 TWh, against a base electricity demand met by 41% hydro + 30% nuclear + 18% wind + 1% gas. Gas is a marginal fuel in Sweden, not a baseload.
Why a small low number is still a signal
Three reasons it matters more than the absolute volume suggests:
1. Northern Lights LNG terminal at Brunnsviksholmen is the principal supply alternative — but cargo scheduling rolls over six to eight weeks. A low storage number means less buffer against scheduling slippage.
2. Cross-border interconnection with Denmark runs through the Dragør–Klagshamn link, capped at ~9 GWh/d. That can refill the Swedish system in roughly 110 days at maximum capacity — not in a hurry.
3. The political optics. The Riksdag adopted the EU's 80% by November 1 storage filling target. Coming in below 60% in May is unusual for the Nordic flank and signals that the refill won't be smooth.
The two other low-storage cases
Netherlands 13.3%: Bergermeer is the largest single asset in the EU at 41 TWh working volume. A low % at Bergermeer matters absolutely as well as relatively — at full capacity the field can deliver 175 mcm/d, which is meaningful for North-West European balancing.
Belgium 20.8%: Loenhout is the only large facility (8 TWh), tightly coupled to the Antwerp industrial cluster. The TTF spot at €48.68/MWh is the signal Belgian utilities will read in their summer hedging.
What shortage.life will be watching
- Weekly AGSI+ delta — injection rate must accelerate past 0.5 pp/week to make November
- TTF–NBP basis — UK pulls cargoes if it widens
- Norwegian pipeline scheduled outages, June–August
