Timeline: Nord Stream 2 Gas Pipeline's Difficult Birth

Russia has resumed construction of the politically-charged Nord Stream 2 gas pipeline to Germany, laying pipes after a one-year hiatus prompted by U.S. sanctions, the pipeline operator said on Friday.

An alleged nerve agent attack on Kremlin critic Alexei Navalny in August was the latest political controversy to hit the nearly-completed Nord Stream 2 gas pipeline, as Germany debates whether to halt the project as part of potential sanctions against Russia.

Led by Russia's Gazprom with Western partners, the pipeline, which would double the capacity of the existing Nord Stream 1 link, is more than 90% completed and scheduled to operate from early 2021.

The project has split the European Union, with some members saying it will undermine traditional gas transit state Ukraine and increase energy reliance on Russia.

The United States, keen to increase liquefied natural gas (LNG) sales to Europe, also opposes the pipeline and has targeted some companies involved with sanctions.

Here are some key dates in Nord Stream 2's development:

2011

November: Nord Stream 2's forerunner, Nord Stream 1, a consortium mainly led by Gazprom, starts deliveries through a twin pipeline system to Europe under the Baltic Sea. The system's 55 billion cubic metres (bcm) capacity is equivalent to enough gas to heat 26 million households.

Gazprom and Western partners start looking into expanding the system with another two pipelines to add a further 55 bcm of capacity. The project is estimated to cost 9.5 billion euros ($11.3 billion).

May: An EU court throws out a challenge to EU gas rules from the operators of the Nord Stream 1 and Nord Stream 2 pipelines, saying it was up to individual members states to enforce them.

June: Poland starts proceedings against Gazprom, alleging the company has not cooperated with the country's anti-monopoly proceedings regarding Nord Stream 2. [nW8N28600O

Oct. 7: Poland fines Gazprom more than 29 billion zlotys ($7.6 billion) for building Nord Stream without Warsaw's approval.

Nov. 4: Gazprom files an appeal in a Polish court against that fine.

Nov. 28: Nord Stream 2 says it plans to resume pipe-laying work on a 2.6 km stretch of the pipeline before the end of the year.
