PARIS — Russia’s gas price dispute with Ukraine escalated Tuesday, disrupting deliveries to the European Union in the midst of a bitter cold spell, with a number of countries reporting that gas supplies had been suspended or reduced, and Germany predicting a possible shortage.
Bulgaria, Romania, Greece, the Czech Republic, Austria and other countries including Croatia, Macedonia and Turkey reported that gas supplies had been suspended or reduced after Gazprom, the Russian gas monopoly, reduced gas shipments through Ukraine.
Aleksandr I. Medvedev, a deputy chief executive of Gazprom, said at a news conference in London that three export pipelines within Ukraine had been shut down early Tuesday morning.
“The flow to Europe through the Ukraine is now about seven times less than the norm and the situation continues to deteriorate,” Mr. Medvedev said. “The Ukraine is in obvious breach of its commitments.”
“We face this challenge together with our European colleagues,” he added. “It’s a question of absolute irresponsibility,” and he called on the European Union to “go after Ukraine.”
Nonetheless, he said, Gazprom is “ready to go to the negotiation table any day, any minute.”
The European Commission and the European Union presidency responded to the Russian move with a statement demanding that “gas supplies be restored immediately to the E.U. and that the two parties resume negotiations at once with a view to a definitive settlement of their bilateral commercial dispute.” They said the E.U. would seek to “intensify the dialogue with both parties so that they can reach an agreement swiftly.”
E.ON Ruhrgas, the German gas company, said its gas supplies via Ukraine at its Waidhaus station had been “massively reduced,” and predicted that deliveries would completely stop in the next few days. E.ON said it would soon be unable to meet demand if supplies were not restored and temperatures remained low.
The Bulgarian Energy Ministry said that its deliveries were suspended early Tuesday, including gas intended for transit to Turkey, Greece and Macedonia. Bulgaria gets the vast majority of its gas from Russia. Bulgarian leaders announced that natural gas supplies would be slashed by two thirds on Tuesday, forcing the nation to rely on reserves in the village of Chiren in central Bulgaria that could last up to two months.
Prime Minister Sergey Stanishev said that the storage facility had reserves of 570 million cubic meters of gas and could provide about 4.5 million cubic meters daily — about a third of the country’s normal consumption.
The Turkish energy minister, Hilmi Guler, on Tuesday told reporters in Ankara that the Russian gas from a pipeline that transits Ukraine had been completely cut. But Turkey is seeking to increase deliveries of Russian gas via a Black Sea pipeline, he said.
In Prague, the Czech pipeline operator RWE Transgas said the flow of gas “delivered by the transit pipe line system through the Ukraine and Slovakia to the Czech republic and other EU countries has dropped significantly.” It said it would increase purchases of Norwegian gas delivered via another pipeline.
The Romanian Economy Ministry also released a statement saying that a pipeline delivering Gazprom gas had been shut down. A second pipeline in the north of the country continues to operate, however. In Vienna, the Austrian energy company OMV said its supply of Russian gas via Gazprom was down 90 percent Tuesday. Werner Auli, a member of the OMV board said in a statement: “The supply of natural gas to our customers is still secured for the time being.”
Gazprom began reducing deliveries Monday for transit through Ukraine to Western European customers, saying it was seeking to make up for gas stolen by Ukraine. The Gazprom chief executive, Aleksei B. Miller, said in a conversation with Prime Minister Vladimir V. Putin broadcast Monday on Russian state television that Gazprom would reduce exports bound for Western Europe through Ukrainian pipes by the same amount that it accused Ukraine of diverting. Gazprom had already cut off all fuel supplies meant for Ukraine over the dispute.
It said that any countries that suffer shortages as a result should blame Ukraine for not paying a fair price for Russia’s natural gas. Russia and Ukraine, which has a pro-Western government, have been haggling over gas prices for years, in disputes that often carry political overtones. In the current fracas, Ukraine resisted an increase in Russian gas to $250 per 1,000 cubic meters from the current $179.50. Russia then raised the price to $418 for the same volume and again to $450.
