Gas flows from Germany to Poland via the Yamal-Europe pipeline, which usually sends Russian gas westwards into Europe, continued at low volumes on Monday morning, data from German network operator Gascade showed.
The section of the pipeline between Poland and Germany has been operating in reverse since December, putting upward pressure on European gas prices.
Eastbound flows to Poland from Germany via the Mallnow metering point were at 1.07 million kilowatt hours per hour (kWh/h), unchanged from the weekend and below 1.5 million kWh/h seen on Thursday and Friday.
The operator said there were renominations, or bids, for eastbound gas supplies at the same amount of 1.5 kWh/h until Tuesday morning.
The pipeline usually accounts for about 15% of Russia's annual gas exports that flow westwards to Europe and Turkey.
Russian gas exporting monopoly Gazprom, which can book pipeline capacity at daily auctions, had not ordered any transit capacity for February.
European benchmark gas prices jumped to a record 184.95 euros per megawatt hours (MWh) on Dec. 21 when the Yamal system reversed flow.
High prices have discouraged purchases of spot volumes from Russia, with buyers instead tapping stored gas in Europe, where storage levels have fallen below their five-year average.
The West has accused Russia of withholding gas to help drive prices to record levels and, in part, to increase pressure on German regulators to approve the new Nord Stream 2 link that would boost Russian gas flows to Europe. Russia denied the allegations.
