The Finnish company said the move by Russia would not cause disruptions in supplies.
“It is highly regrettable that natural gas supplies under our supply contract will now be halted,” Gasum CEO Mika Wiljanen said in a statement.
“However, we have been carefully preparing for this situation and provided that there will be no disruptions in the gas transmission network, we will be able to supply all our customers with gas in the coming months,” he said.
Gasum said it will continue to provide Finnish customers with natural gas through the Balticconnector pipeline that connects Finland with Estonia.
Finland announced a 10-year agreement with US-based Excelerate Energy to lease a floating storage and delivery vessel to provide liquefied natural gas to the region.
