Germany's gas storage today, against last year and the five-year average

THE SHORT ANSWER · GAS DAY 22 SEPTEMBER 2026

On gas day 22 September 2026, German storage held 141 TWh (57.0% full) and was still filling: over the past seven days it gained 365 GWh a day on average. At the average net withdrawal of the past ten winters from 1 November to 31 March, 851 GWh a day, it would last 166 days. Even if every German store withdrew at its declared maximum rate, it would last at least 20 days. The fill is 19.7 points below the same date last year (76.7%) and 27.6 points below the five-year average (84.6%).

These are days of cover: how long the gas in storage would last on its own. Pipeline gas from Norway and through neighbouring countries, LNG through the North Sea and Baltic terminals and a little domestic production supply most of the gas Germany uses in winter, so neither figure is a countdown to running out.

01 · The two runways

How long storage would last, and against what

The first runway divides the gas in storage by the net withdrawal of the past seven gas days. While storage is still filling there is no withdrawal to divide by, so the page uses the average pace of past winters for this calendar date instead. The second runway divides the same gas by the most that could be withdrawn in a day. It is a lower bound: a store's maximum rate falls as it empties, so withdrawing flat out would in practice last longer than this.

At the same 851 GWh a day, today's stock lasts 59 days fewer than it did on 22 September 2025, and 82 days fewer than the five-year average for this date (2021 to 2025).

Ten-winter pace: the average net withdrawal of the past ten winters from 1 November to 31 March, read from GIE AGSI+ daily stock. Maximum withdrawal: Germany's declared technical maximum on AGSI+, the sum of what each store says it can send out in a day. Stores cannot hold that rate as they empty, so withdrawing flat out would in fact last longer. Five-year averages take the same calendar date in each of the five previous years and need at least three of them. Source: GIE AGSI+.

02 · The law

The fill levels German law requires this winter

Germany's storage ordinance, the Gasspeicherfüllstandsverordnung of 5 May 2025 (BGBl. 2025 I Nr. 130), sets the level each storage facility must reach, in place of the higher defaults in section 35b of the Energy Industry Act:

DateEvery facilityExceptions
1 November 202680%45% in Bad Lauchstädt, Frankenthal, Hähnlein, Rehden, Stockstadt and Uelsen, because they inject and withdraw far more slowly and because of where they are
1 February 202730%40% in Bierwang, Breitbrunn, Inzenham-West and Wolfersberg

There is no 1 September or 1 October target in force. The ordinance expires at the end of 31 March 2027, as do the storage rules in the Energy Industry Act (section 35i). The Bundesnetzagentur says it assesses the gas situation with particular focus on the 30% target for 1 February 2027. The targets bind each facility, not the German total, which is why the site table below marks the named sites and the chart carries no target line.

At EU level, Regulation (EU) 2025/1733 lets each member state reach the 90% filling target at any point between 1 October and 1 December, and in difficult market conditions deviate from it by up to 10 percentage points.

Checked against the ordinance text, the Federal Law Gazette entry, section 35i of the Energy Industry Act (as last amended 23 July 2026) and the Bundesnetzagentur's gas supply page on 24 September 2026.

05 · Questions

Questions people ask about Germany's gas storage

Wie voll sind die Gasspeicher in Deutschland?

Am Gastag 22. September 2026 waren die deutschen Gasspeicher zu 57,0 % gefüllt (141,0 TWh). Zum Vergleich: vor einem Jahr waren es 76,7 %, im Fünfjahresdurchschnitt für diesen Tag 84,6 %. Die Speicher in der EU insgesamt waren zu 70,2 % gefüllt. Quelle: GIE AGSI+. Nach der Gasspeicherfüllstandsverordnung müssen die meisten Speicher am 1. November zu 80 % gefüllt sein, sechs Speicher mit langsamer Ein- und Ausspeicherung wie Rehden zu 45 %, und am 1. Februar zu 30 % (vier Speicher: 40 %).

How full is German gas storage compared with last year and the five-year average?

On gas day 22 September 2026 German storage was 57.0% full, holding 141 TWh. That is 19.7 points below the 76.7% of the same date last year, and 27.6 points below the five-year average of 84.6%.

How many days of gas does Germany have?

On gas day 22 September 2026, German storage held 141 TWh (57.0% full) and was still filling: over the past seven days it gained 365 GWh a day on average. At the average net withdrawal of the past ten winters from 1 November to 31 March, 851 GWh a day, it would last 166 days. Even if every German store withdrew at its declared maximum rate, it would last at least 20 days. These are days of cover: how long the gas in storage would last on its own. Pipeline gas from Norway and through neighbouring countries, LNG through the North Sea and Baltic terminals and a little domestic production supply most of the gas Germany uses in winter, so neither figure is a countdown to running out.

What storage levels does German law require this winter?

Under the Gasspeicherfüllstandsverordnung of 5 May 2025, each storage facility must be at least 80% full on 1 November, except six slower sites (Bad Lauchstädt, Frankenthal, Hähnlein, Rehden, Stockstadt and Uelsen), which must reach 45%. On 1 February each must hold at least 30%, and Bierwang, Breitbrunn, Inzenham-West and Wolfersberg 40%. The ordinance and the storage rules in the Energy Industry Act expire at the end of 31 March 2027. The targets apply to each facility, not to the German total. Checked against the ordinance text on 24 September 2026.

How full is Rehden, Germany's largest gas storage site?

On gas day 22 September 2026 UGS Rehden held 4.1 TWh of its 35.7 TWh working volume, 11.6% full. It is one of the six sites the ordinance allows to reach 45% rather than 80% on 1 November, citing their slow injection and withdrawal and their location.

Is Germany running out of gas?

Germany does not live on storage alone, so storage running low is not the same as running out. On gas day 22 September 2026 its stores held 141 TWh; even withdrawn at their declared maximum every day, that would last at least 20 days. Through the winter, pipeline gas from Norway and through neighbouring countries and LNG keep arriving, and storage covers the rest and the cold spells. What matters is how low storage runs by February and March, which this page tracks against past winters.

Method

How the days are worked out

  • Past-week pace. Gas in German storage at the end of the gas day, divided by the fall in storage over the past seven gas days, divided by seven. Shown only while storage is being drawn down.
  • Ten-winter pace. The average net withdrawal of the past ten winters in Germany over the part of the withdrawal season still ahead of this calendar date. Today that is 851 GWh a day.
  • Lower bound. Maximum withdrawal: Germany's declared technical maximum on AGSI+, the sum of what each store says it can send out in a day. Stores cannot hold that rate as they empty, so withdrawing flat out would in fact last longer. The per-country figure from the Voltstack deliverability index is not yet published, so this page uses the declared maximum, a looser but still valid lower bound.
  • Comparisons and screening. The same calendar date in each of the five previous years. Every AGSI+ record passes the storage tracker's plausibility screen; a record that fails is left out and shown as n/a, never replaced with an older number.

GIE AGSI+ publishes each gas day at 19:30 CET the following day. This page refreshes every six hours. No prices are used or shown.
