Gas Pipeline Shutdown Starts Amid German Suspicion of Russia

BERLIN (AP) -- A major gas pipeline from Russia to Germany shut down for annual maintenance on Monday amid German concern that Russia may not resume the flow of gas as scheduled.

The Nord Stream 1 pipeline, Germany's main source of Russian gas, is scheduled to be out of action until July 21 for routine work that the operator says includes "testing of mechanical elements and automation systems." The operator's data showed the gas flow dropping as planned on Monday morning.

German officials are suspicious about Russia's intentions, particularly after Russia's Gazprom last month reduced the gas flow through Nord Stream 1 by 60%. Gazprom cited technical problems involving a gas turbine powering a compressor station that partner Siemens Energy sent to Canada for overhaul and couldn't be returned because of sanctions imposed over Russia's invasion of Ukraine.

Canada said over the weekend that it would allow the part to be delivered to Germany, citing the "very significant hardship" that the German economy would suffer without a sufficient gas supply.

German politicians have dismissed Russia's technical explanation for last month's reduction in gas flows through Nord Stream 1, saying the decision was a political gambit to sow uncertainty and push up prices.

German Vice Chancellor Robert Habeck has said he suspects that Russia may cite "some little technical detail" as a reason not to resume gas deliveries through the pipeline after this month's maintenance.

The head of Germany's network regulator, the Bundesnetzagentur, said "no one can say exactly" whether the gas will be switched back on.

"We have very varied signals from Russia," Klaus Mueller told ZDF television. "There are Kremlin spokespeople who say that, in combination with the Siemens turbine, they can deliver significantly more again; but there have also been very martial messages from the Kremlin."

On Sunday, Ukraine's energy and foreign ministries said in a joint statement that the return of Nord Stream 1 turbines "is adjusting the sanctions regime to the whims of Russia."

Germany and the rest of Europe are scrambling to fill gas storage in time for winter and reduce their dependence on Russian energy imports. Germany, which has Europe's biggest economy, has been getting about 35% of its gas to power industry and generate electricity from Russia.

Last month, Habeck activated the second phase of Germany's three-stage emergency plan for natural gas supplies, warning that Europe's biggest economy faced a "crisis" and storage targets for the winter were at risk.

Separately, Italian energy company ENI said Gazprom was cutting its Monday gas delivery by about a third compared to the average in recent days. ENI said in a statement that Gazprom would provide 21 million cubic meters of gas, compared to an average of about 32 million cubic meters.
