On July 11, Nord Stream 1 was shut down for routine maintenance for 10 days.
Earlier on Thursday, the Agence France-Presse news agency reported, citing Nord Stream AG, the pipeline's operator, that gas started flowing via the Nord Stream 1 pipeline after maintenance works.
In mid-June, Russian energy giant Gazprom significantly reduced gas supplies via the Nord Stream 1 pipeline due to delays in maintenance work on turbines by German and Canadian companies, forcing EU countries to tap into winter gas reserves and consider returning to coal production.
