European Energy Markets: EU gas storage hits 2018 low- How full is European gas storage right now?
- As of 9 April 2026, EU gas storage stood at 28.92% full (327 TWh) according to GIE AGSI+, the lowest level at this point in the year since 2018 and 6-20 percentage points below the five-year average.Source: GIE AGSI+
- What is GIE AGSI+ and how do I read it?
- GIE AGSI+ is the Gas Infrastructure Europe platform that publishes daily EU underground gas storage levels by country. It is the official data source for EU storage regulation and is freely accessible online.
- Why is European gas storage so low in spring 2026?
- EU storage entered 2026 already below seasonal norms after a cold winter, then faced additional pressure from the Qatar Force majeure following the Ras Laffan LNG facility strikes. AGSI+ recorded the lowest seasonal level since 2018 by April 2026.Source: GIE AGSI+
- What storage level does Europe need to reach before winter?
- EU regulations previously required 90% storage by 1 November. In April 2026 the Commission reduced this to 80%, with flexibility to 70% in exceptional circumstances, citing the AGSI+ data showing the refill challenge.Source: European Commission
Background
GIE AGSI+ is the Gas Infrastructure Europe Aggregated Gas Storage Inventory, the primary public data platform for tracking EU underground gas storage levels in real time. On 9 April 2026 it recorded EU storage at 28.92% full (327 TWh), the lowest reading at this seasonal point since 2018 and six to twenty percentage points below the five-year seasonal average of 40-50%. This figure directly triggered the Commission review of storage filling targets.
GIE AGSI+ is operated by Gas Infrastructure Europe, the Brussels-based trade association for European gas infrastructure operators, and aggregates storage data from operators across 28 European countries. The platform publishes daily injection and withdrawal data, stock levels, and trend analytics that underpin regulatory decisions, market pricing, and emergency planning under the EU Gas Security of Supply Regulation.
Because AGSI+ is the source of record for storage data referenced in Commission regulations and ENTSOG seasonal outlooks, its daily readings carry direct market impact. TTF futures and spot gas prices trade on the AGSI+ numbers; when storage falls below seasonal averages, it amplifies price volatility. The April 2026 seasonal low reading helped push TTF to EUR 70/MWh in March before the Iran ceasefire relief.
