Austria's gas storage facilities two-thirds full – Vienna looks confidently toward winter

Production in Wittau strengthens domestic supply

The Wittau site, where production has been expanded in recent months, plays a central role in this. The increased domestic generation reduces dependence on deliveries from abroad. Hattmannsdorfer described this as an important contribution to security of supply, particularly against the backdrop of the uncertain situation on international energy markets.

The Strategic Gas Reserve, which Austria built up following the energy shock of recent years, is also nearly fully filled according to the ministry. This reserve is designed to cushion short-term bottlenecks in emergencies and is conceived as an additional buffer alongside commercial storage facilities.

The background is the experience from the years after 2022, when Russia fell out as an important gas supplier for many EU states and prices on European trading venues temporarily rose sharply. At that time, Austria had taken extensive measures to fill storage facilities as quickly as possible over the summer and reduce dependence on individual suppliers.

Background: Lessons from the gas shock

Austria currently sources natural gas, among other things, via pipelines from Germany and via liquefied natural gas (LNG) deliveries that arrive via European terminals. The import routes are considered diversified and stable according to AGGM's assessment. Hattmannsdorfer warned, however, that the situation on world markets – also with regard to developments in Iran and other production regions – must continue to be monitored.

The minister also announced that the federal government intends to further advance the expansion of renewable energies and domestic gas production. In the medium term, the share of domestically produced gas should continue to rise in order to make supply more independent of international fluctuations.

AGGM Managing Director Christoph Dolna-Gruber explained that the current filling levels meet expectations and that the industry plan for winter preparation is being adhered to. He simultaneously called for energy to continue to be used sparingly in order to keep storage levels high until the start of the heating season.

Outlook for the heating season

With a view to the coming weeks, operators expect that storage levels will continue to rise until the start of the heating period in October. A prerequisite for this is that no unexpected technical problems occur at import pipelines or storage facilities. AGGM intends to closely monitor developments and provide regular updates on the state of filling.

From the Energy Ministry's perspective, the current situation is a sign that the measures taken since 2022 – from the diversification of import routes through the build-up of the Strategic Gas Reserve to the strengthening of domestic production – are working. Hattmannsdorfer spoke of a "deutlich verbesserten Versorgungssicherheit" compared to previous years.
