Russia delivered less gas to Europe on Wednesday in a further escalation of an energy stand-off between Moscow and the European Union that will make it harder, and costlier, for the bloc to fill up storage ahead of the winter heating season.

The cut in supplies, flagged by Gazprom (GAZP.MM) earlier this week, has reduced the capacity of Nord Stream 1 pipeline - the major delivery route to Europe for Russian gas - to a mere fifth of its total capacity.

A day earlier, EU countries approved a weakened emergency plan to curb gas demand after striking compromise deals to limit cuts for some countries, hoping lower consumption will ease the impact in case Moscow stops supplies altogether.


While Moscow has blamed various technical issues for the supply cuts, Brussels has accused Russia of using energy as a weapon to blackmail the bloc and retaliate for Western sanctions over its invasion of Ukraine.

On Wednesday, physical flows via Nord Stream 1 tumbled to 14.4 million kilowatt hours per hour (kWh/h) between 0700 and 0800 GMT from around 28 million kWh/h a day earlier, less than a week after the pipeline restarted following a scheduled 10-day maintenance period.

Klaus Mueller, head of Germany's network regulator, said the country could still avoid a gas shortage that would prompt its rationing.

Germany, Europe's top economy and its largest importer of Russian gas, has been particularly hit by supply cuts since mid-June, with its gas importer Uniper (UN01.DE) requiring a 15 billion euro ($15.21 billion) state bailout as a result.

Uniper and Italy's Eni (ENI.MI) both said they received less gas from Gazprom than in recent days.

Mueller issued another plea to households and industry to save gas and avoid rationing.

"The crucial thing is to save gas," Mueller said. "I would like to hear less complaints but reports (from industries saying) we as a sector are contributing to this," he told broadcaster Deutschlandfunk.

German industry groups, however, warned companies may have no choice but cut production to achieve bigger savings, pointing to slow approval for switching from natural gas to other, more polluting fuels. 

Germany is currently at Phase 2 of a three-stage emergency gas plan, with the final "emergency" phase to be launched once rationing can no longer be avoided.

"If you asked me whether it (a gas shortage) is imminent, then I would say that if flows remain at 20% and if we can still add to storage facilities in the coming days and weeks, then we do not yet have a physical gas shortage, which would be the prerequisite for Phase 3," Mueller said.
