Russian gas flows via the Nord Stream 1 pipeline are seen restarting on time on Thursday after the completion of scheduled maintenance, two sources familiar with the export plans told Reuters.

The pipeline, which accounts for more than a third of Russian natural gas exports to the European Union, was halted for ten days of annual maintenance on July 11.

Speaking on anonymity because of the sensitivity of the issue, the sources told Reuters the pipeline was expected to resume operation on time, but at less than its capacity of some 160 million cubic meters (mcm) per day.
