Russia's Gazprom said it would again reduce gas deliveries through Nord Stream 1 by 20% for 'repairs,' cutting the current flow in half. The new blow to supply comes as Europe scrambles to store gas for winter.
That would correspond to 20% of the pipeline's capacity. The current flow of gas into Germany is only at 40%.
The company said it was halting the operation of another turbine due to the "technical condition of the engine".
The full capacity of Nord Stream 1 is over 160 cubic meters of gas exported daily. Stopping the turbine will result in reduced capacity of 33 million cubic meters. Gazprom said the production capacity is to be reduced at Russia's Portovaya compressor station.
"We are monitoring the situation very closely in close exchange with the Federal Network Agency and the gas crisis team,'' the German Economics Ministry said.
"According to our information, there is no technical reason for a reduction in deliveries,'' it added.
German Economy Minister Robert Habeck told Germany's dpa news agency Monday that "Russia is breaking contracts and blaming others," adding that Russian President Vladimir Putin is playing a "duplicitous game."
Von der Leyen told German news agency dpa, "Even member states that hardly purchase any Russian gas cannot escape the effects of a potential supply stop on our internal market."
EU fears Russia may cut off gas deliveries
Tension over turbines
Monday's announcement of the latest cut comes after the Russian company raised questions about the return of a different turbine that was serviced in Canada, saying it wasn't satisfied with the documents it has received.
"Gazprom has studied...the documents, but has to acknowledge that they do not remove the previously identified risks and raise additional questions," it said in a statement.
"Additionally, there are still open questions from Gazprom regarding the EU and UK sanctions, the resolution of which is important for the delivery of the engine to Russia and the urgent overhaul of other gas turbine engines for the Portovaya compressor station," the statement said.
Turbine maker Siemens dismissed the concerns saying the turbine that was transported from Canada to Germany could be shipped immediately.
"The maintenance of our turbines is and remains a routine procedure. During the last 10 years of maintenance there have been no significant complications," Siemens Energy said, adding that Gazprom had not provided required customs documents.
Last week Putin seemed to foreshadow the latest cut when he said: "There are two functioning machines there. They pump 60 million cubic meters per day ... If one is not returned, there will be one, which is 30 million cubic meters."
