The Danish energy agency Örsted warned that Gazprom Export could cut off gas supplies to the Danish energy company because it refused to pay in rubles, Reuters reported.

Gazprom Export continues to demand that Orsted pay for gas supplies in rubles, Orsted said in a statement. 

The Danish Energy Agency has said that cutting off Russian gas supplies will have no immediate consequences for Denmark. The agency also said it has a contingency plan in place in the event of a shortage of gas. Orsted said he expects it will be possible to buy gas on the European market.

If deliveries will be terminated after Orsted's payment deadline of May 31st.

Poland, Bulgaria and Finland refused to comply with Moscow's demand to change the method of payment, and subsequently the gas supply was cut off.

German, Italian and French companies have said they will use the ruble scheme to maintain supplies.

Under the Russian ruble payment system, buyers must deposit euros or dollars into an account with Gazprombank, where the bank converts them into rubles.

Orsted has previously said that his contract with Gazprom accounts for the vast majority of Danish gas consumption and about 1.5% of total Russian supplies to Europe, which totaled about 155 billion cubic meters last year.

Orsted sold his oil and gas assets in 2017 to focus on offshore wind power, but maintains a long-term gas deal with Russia's Gazprom that runs until 2030.
