MOSCOW, September 22. /TASS/. Gazprom has resumed gas supplies via the Power of Siberia pipeline following the completion of scheduled maintenance, the company announced on Tuesday.

"Contractually stipulated scheduled maintenance has been successfully completed on the Power of Siberia gas pipeline. The maintenance was carried out from September 15 to 22, with all activities fully executed. Gas transportation resumed today," the company said in a statement.

The gas giant noted that under the sales and purchase agreement between Gazprom and CNPC, maintenance of the Power of Siberia's equipment and systems is conducted twice a year, in the spring and autumn.

In 2025, Gazprom became China's largest gas exporter. Supplies via the Power of Siberia pipeline totaled 38.8 billion cubic meters (bcm) of gas, exceeding initial contractual obligations by 800 million cubic meters.

Power of Siberia is the largest gas transportation system in eastern Russia, with an export capacity of 38 bcm per year. The first pipeline supplies of Russian gas to China via the eastern route began in December 2019 under a 30-year contract signed in 2014 between Gazprom and China's CNPC. The total volume of supplies over the contract's duration will exceed 1 trillion cubic meters of gas, with the total contract value estimated at $400 billion.
