Russian gas flows to Austria were halted for a second day on Sunday due to a price dispute but other buyers in Europe stepped in to buy unsold volumes, companies, sources and data showed.

Russia, which before the Ukraine war was Europe's single largest gas supplier, has lost most buyers on the continent as the European Union tries to reduce its reliance on Russian energy.

Russian gas is still sold in large quantities to Slovakia and Hungary, as well as to the Czech Republic, which does not have a direct contract, while smaller quantities go to Italy and Serbia.

Gazprom on Saturday halted supplies to Austria's OMV after the Austrian company threatened to seize some of the Russian state company's gas as compensation for an arbitration award it won in a contractual dispute.

Gazprom confirmed that gas flows to Austria remain halted on Sunday but total daily supplies via Ukraine, the main route for Russian gas to the European Union, will remain at 42.4 million cubic metres, roughly the same volume every two days over the past year.

Austria was receiving 17 million cubic metres before the supply was cut, and now these quantities are finding new buyers in Europe.

At its highest level ever, Russia supplied Europe with about 35 percent of its gas needs, but since the war in Ukraine began in 2022, Gazprom has lost market share to Norway, the United States and Qatar.

The company's remaining flows to Europe may not last long with the Soviet-era pipeline through Ukraine set to close at the end of this year, as Kyiv does not want to extend the transit agreement.
