Russian gas producer Gazprom has cut off gas supplies to the Danish company Orsted and Shell Energy in connection with a contract to supply gas to Germany, the company said on Wednesday, citing the companies’ inability to make payments in rubles.

Gazprom has already cut off supplies to the Dutch gas trader GasTerra, as well as to Bulgaria, Poland and Finland after they refused to pay for gas in Russian rubles, as demanded by Moscow in response to Western sanctions over the Russian-Ukrainian conflict.

However, German, Italian and French companies have said they will use Moscow’s payment scheme to ensure they can keep up with deliveries.

Bundesnetzagentur, Germany’s network regulator, said on Wednesday that Shell Europe accounts for only a small amount of gas supplies that can be sourced from other parties.
