Overview
Nord Stream AG was incorporated in Zug, Switzerland, on 30 November 2005 as the consortium behind the Nord Stream submarine gas pipeline project. The project involved Gazprom and several European energy and infrastructure companies, aiming to establish a direct offshore gas transport route from Russia to Germany. The Nord Stream 1 pipeline system began delivering gas in 2011 and became an important part of the European gas supply network. In 2022, Nord Stream 1 stopped supplying gas due to turbine issues and was severely damaged in explosions on 26 September. The Nord Stream 2 project, although completed, never received German approval and never entered commercial operation.
History
Nord Stream AG was incorporated in Zug, Switzerland, on 30 November 2005 to serve as the consortium behind the Nord Stream submarine gas pipeline project. The venture brought together Gazprom and several European energy and infrastructure companies. Gazprom International Projects held 51%, while Wintershall Dea, PEG Infrastruktur, Gasunie, and Engie held minority positions. The project was intended to create a direct offshore route for Russian natural gas to Germany, reducing reliance on intermediate transit corridors. The first pipeline system, later known as Nord Stream 1, connected Vyborg on Russia's Baltic coast with Greifswald in Germany. It consisted of two parallel submarine lines and began gas deliveries in 2011. Over its operating life, the system became an important part of the European gas-supply network. The cited material states that it transported more than 450 billion cubic metres of gas to Europe. In 2020, the German Federal Network Agency again emphasized the pipeline's contribution to energy-supply security. Nord Stream AG's history was closely linked in public discussion with Nord Stream 2, although the two projects were not identical. Nord Stream 2 was developed as a separate additional pipeline project and was technically completed, but German authorities halted its permitting process after Russia's invasion of Ukraine. It consequently never delivered commercial gas. Nord Stream 1 continued to be the operating system associated with Nord Stream AG until 2022. Nord Stream 1 gas deliveries ended on 31 August 2022. The interruption was initially presented as a short maintenance stoppage. Two days later, Nord Stream AG announced that flows would not resume indefinitely because an engine-oil leak had affected the main turbine at the Portovaya compressor station near St Petersburg. The supply suspension occurred amid a major deterioration in relations between Russia and European states and during the war in Ukraine. On 26 September 2022, explosions caused severe damage to both Nord Stream 1 lines. One of Nord Stream 2's two lines was also destroyed. The supplied reference characterizes the Nord Stream 1 pipelines as damaged beyond repair. The incident prompted international investigations, political disputes, and insurance litigation, but the provided material does not establish the identity of the perpetrator. The supplied reference further states that in July 2026 London's High Court rejected a EUR 579 million insurance claim brought by Nord Stream AG in relation to the sabotage. The court reportedly relied on a war-exclusion provision and considered the Russo-Ukrainian war a significant cause of the loss, despite the absence of a specifically identified saboteur. The available material does not clarify whether Nord Stream AG remains an operating corporate entity, is being wound down, or continues solely for legal and asset-related purposes. Its current status is therefore recorded as unknown.

Nord Stream 1 begins gas deliveries
[1]The Nord Stream 1 submarine pipeline began transporting natural gas from Russia to Germany and subsequently served European gas markets.

French energy company joins the project
[1]GDF Suez, later renamed Engie, signed a memorandum of understanding with Gazprom to acquire a 9% interest. The transaction reduced the stakes held by Wintershall and E.ON-associated PEG Infrastruktur.

Nord Stream AG incorporated
[1]The consortium was incorporated in Zug, Switzerland, on 30 November 2005 to develop and operate the Nord Stream submarine gas pipeline project.
Products and positioning
A cross-border gas-transmission infrastructure consortium focused on direct submarine delivery of Russian natural gas to Germany and the wider European market.
Submarine natural-gas pipeline · 2011
Nord Stream 1
Nord Stream 1 was a twin-line submarine natural-gas pipeline linking Vyborg in Russia with Greifswald in Germany under the Baltic Sea. It was the principal infrastructure associated with Nord Stream AG and began gas deliveries in 2011. The system transported Russian gas directly to the European market and was later damaged beyond repair in the September 2022 explosions.
Submarine natural-gas pipeline project
Nord Stream 2
Nord Stream 2 was a separate, related pipeline project intended to add another direct offshore gas route from Russia to Germany. It was technically completed but did not receive the required German permitting and never delivered gas. One of its two lines was damaged in September 2022.
Brand decisions
2022
Suspend Nord Stream 1 deliveries indefinitelyOtherBackground
Nord Stream 1 flows were initially stopped for scheduled maintenance, but Nord Stream AG later cited an oil leak affecting the main gas turbine at the Portovaya compressor station.
Action taken
The company announced on 2 September 2022 that gas supplies would remain shut off indefinitely until the turbine issue was resolved.
Aftermath
The pipeline did not resume normal deliveries before the September 2022 explosions severely damaged both Nord Stream 1 lines.
2022
Nord Stream 2 permitting haltedOtherBackground
Germany halted the permitting process for Nord Stream 2 following Russia's invasion of Ukraine.
Action taken
The project was prevented from entering commercial operation despite being technically ready.
Aftermath
Nord Stream 2 never delivered gas, and one of its two lines was later destroyed in the September 2022 pipeline incident.
