Nord Stream 1 pipeline to Europe from Russia restarts after gas shutdown

The Nord Stream 1 pipeline under the Baltic Sea to Germany had been closed since July 11 for annual maintenance work.

Natural gas started flowing through a major pipeline from Russia to Europe on Thursday after a 10-day shutdown for maintenance – but the gas flow remained well short of full capacity and the outlook was uncertain, which leaves Europe still facing the prospect of a hard winter.

The Nord Stream 1 pipeline under the Baltic Sea to Germany had been closed since July 11 for annual maintenance work. Amid growing tensions over Russia’s war in Ukraine, German officials had feared that the pipeline _ the country’s main source of Russian gas, which recently has accounted for around a third of Germany’s gas supplies – might not reopen at all.

Network data showed gas beginning to arrive through the Nord Stream 1 pipeline as scheduled after 6 a.m., and the operator said that it had “successfully completed all planned maintenance works.” But deliveries were still far below the pipeline’s full capacity, as they were for weeks before the maintenance break.

The head of Germany’s network regulator, Klaus Mueller, said Russia’s Gazprom had notified deliveries Thursday of about 30% of the pipeline’s capacity. He later tweeted that actual deliveries were above that amount and could reach the pre-maintenance level of some 40%.

That wouldn’t be enough to resolve Europe’s energy crisis. “The political uncertainty and the 60% reduction from mid-June unfortunately remain,” Mueller wrote.

When Gazprom reduced the flow last month, it cited alleged technical problems involving equipment that partner Siemens Energy sent to Canada for overhaul and couldn’t be returned because of sanctions imposed over Russia’s invasion of Ukraine.

The Canadian government earlier this month gave permission for the turbine that powers a compressor station at the Russian end of the pipeline to be delivered to Germany.

The German government has rejected Gazprom’s technical explanation for the gas reduction, charging repeatedly that it was only a pretext for a political decision to sow uncertainty and further push up energy prices. It has said the turbine was a replacement that was only supposed to be installed in September, but that it’s doing everything to deprive Russia of the pretext to reduce supplies.
