Gas demand has fallen after the end of the winter heating season, but European utilities are racing to refill storage ahead of next winter with prices high and supplies uncertain.
“Gas supplies to the Nord Stream gas pipeline can currently be provided in the amount of up to 100 million cubic meters per day (compared to) the planned volume of 167 million cubic meters per day,” Gazprom said in a statement.
It did not provide a timeline for the planned drop in gas flows.
Siemens Energy said a gas turbine that powers a compressor station on the pipeline had been in service for more than 10 years and had been taken to Montreal for a scheduled overhaul. But because of sanctions imposed by Canada, the company has been unable to return the equipment to the customer, Gazprom.
“Against this background we informed the Canadian and German government and are working on a sustainable solution,” Siemens Energy said in a statement.
Also Tuesday, the German government said it is making an emergency loan to a former subsidiary of Gazprom to prevent it from bankruptcy and safeguard the nation's gas supply.
Germany put a government agency in charge of Gazprom Germania in April, saying the move was temporary to bring "order to the conditions" at the company after the Kremlin-controlled parent company cut ties with its subsidiary.
Gazprom Germania, which plays a central role in the trade, transport and storage of natural gas in Germany and neighboring countries, was subsequently slapped with sanctions by Russia in a tit-for-tat move for Western sanctions over Ukraine.
Dpa quoted unnamed government officials saying the loan would be between 9 and 10 billion euros ($9.4 billion to $10.4 billion).
The government said the loan would “avert a bankruptcy and prevent a cascade effect on the market.”
“The money will serve to shore up liquidity and procure replacement gas,” it said in a statement.
The government added that Gazprom Germany also would be renamed Securing Energy for Europe GmbH, or SEFE, as a “clear signal to the market that the goal of the measures taken is to ensure the energy supply in Germany and Europe."
