Russian energy giant Gazprom has halted flows on the Nord Stream 1 gas pipeline to Germany for maintenance from 0100 GMT on August 31 to 0100 GMT on September 3, according to energy market information disclosure platform Seeburger.

The confirmation on timing of the maintenance on the pipeline that runs under the Baltic Sea to Germany continues an energy stand-off between Moscow and Brussels that has helped to accelerate inflation in the region and raised the risk of rationing and recession.

Gazprom flagged the shutdown early this month without giving exact times.

The Kremlin-controlled company has already reduced flows through Nord Stream 1, the single biggest pipeline carrying Russian gas to Germany, to 20 percent of capacity because of what it describes as faulty equipment.

Gas flows via other pipeline routes have also fallen since Russia invaded Ukraine on February 24 in what Moscow calls a “special military operation”.

Nominations for the Nord Stream 1 pipeline have fallen to zero from August 31, 0200 CET, data on the operator's website show.

Flows via Nord Stream 1 were fairly stable on Tuesday at about 20 percent of capacity.

The shutdown follows a 10-day maintenance curtailment in July and has raised fears over whether Russia will resume gas supplies after the shutdown.
