BERLIN — Europe’s energy crisis loomed larger Friday after Russian energy giant Gazprom said it couldn’t resume the supply of natural gas through a major pipeline to Germany for now. The company cited what it said was a need for urgent maintenance work to repair key components — in an announcement made just hours before it had been due to restart deliveries.

The Russian state-run energy company had shut down the Nord Stream 1 pipeline on Wednesday for what it said would be three days of maintenance.

It said in a social media post Friday evening that it had identified “malfunctions” of a turbine and added that the pipeline would not work unless those were eliminated.

The move was the latest development in a saga in which Gazprom has advanced technical problems as the reason for reducing gas flows through Nord Stream 1 — explanations that German officials have rejected as a cover for a political power play following Russia’s invasion of Ukraine.

European utilities have scrambled to find additional supply during the summer months to get ready for the winter’s heating demands, buying expensive liquefied gas that comes by ship, while additional supplies have come by pipeline from Norway and Azerbaijan.

Fears of a winter shortage have eased somewhat as storage has progressed, but a complete cutoff could present Europe with serious difficulties, analysts say. The European Union needs to step up efforts to reduce gas consumption, said energy policy expert Simone Tagliapietra at the Bruegel think tank in Brussels.

The continuing interruptions from Gazprom mean that “a winter with zero Russian gas is the central scenario for Europe.” he said. “There is only one way to prepare for that: reducing gas and electricity demand.”

In recent weeks, Nord Stream 1 has been running at only 20% of capacity.

Russia, which before the reductions started accounted for a bit more than a third of Germany’s gas supplies, has also reduced the flow of gas to other European countries which have sided with Ukraine in the war.

Natural gas is used to power industry, heat homes and offices, and generate electricity. Increasing the amount in reserve has been a key focus of the German government since Russia invaded Ukraine, to avoid rationing for industry as demand rises in the winter.

Germany’s storage facilities are now over 84% full.

The head of Germany’s network regulatory agency, Klaus Mueller, tweeted that the Russian decision to keep Nord Stream 1 switched off for now increases the significance of new liquefied natural gas terminals that Germany plans to start running this winter, gas storage and “significant needs to save” gas.

It is “good that Germany is now better prepared, but now it comes down to everyone,” Mueller added.

Germany’s Economy Ministry said it had “taken note” of Gazprom’s latest announcement and wouldn’t comment on it directly, but added that “we have already seen Russia’s unreliability in recent weeks” and continued efforts to reduce the country’s reliance on Russian energy imports.

“Of course these are difficult times but we will continue to strengthen provisions consistently,” the ministry said in a statement. “Great efforts are still needed but we are on a good path to coping with the situation.”

The European Union has just reached its goal of filling its gas storage to 80%, ahead of a Nov. 1 deadline, despite Russian supply cutbacks.
