Nord Stream 2 will feed gas from Siberia into the continental European grid. : (Bloomberg) -- Russia’s controversial effort to build a natural gas pipeline to Germany plunged into a deeper freeze with Poland’s decision to impose a $7.6 billion fine on its sponsor. The move by the consumer protection regulator in Warsaw raises another hurdle holding up the Nord Stream 2 pipeline, which was weeks away from completion when U.S. sanctions stopped work last year. President Donald Trump and his Polish counterpart are concerned the link would deepen Europe’s reliance on Russia for energy supplies.
