WARSAW/MOSCOW—Poland has fined Russia’s Gazprom more than 29 billion zlotys ($7.6 billion) for building the Nord Stream 2 gas pipeline without Warsaw’s approval, its watchdog said on Wednesday, prompting the company to say it will appeal.
The project has stoked concern about Moscow’s dominance of European energy supplies and attracted U.S. sanctions, although rival sales of Azeri gas and U.S. liquefied natural gas (LNG) may squeeze Russia’s market share in Europe.
