Gazprom announced that it would not resume gas deliveries through the Nord Stream 1 pipeline on September 2 and the Russian government has since made it clear that deliveries would not resume until the EU sanctions against Russia were lifted. This question resolves to "YES" if, at any point between now and March 1, 2023, Gazprom resumes deliveries through Nord Stream 1. This can be as a result of a deal between the EU and Russia or for whatever other reasons, it doesn't matter for the purposes of this market, the outcome will be only be determined by whether gas deliveries resume, no matter the reason. The question will also resolve to "YES" if Gazprom temporarily resumes deliveries but stops them again before March 1, 2023.

EDIT: In response to M's comment below, I will also stipulate that unless volumes are greater than 5% of the pipeline's capacity, the question will resolve to "NO".
