Bulgaria’s interim energy minister declared that the Balkan nation will have to have discussions with Russia’s Gazprom to resume gas deliveries that were suspended in April after the government pledged to secure sufficient supplies for the winter, Reuters reported.

Rossen Hristov said that talks with the Russian company would be necessary to secure cheaper gas for the nation, but he did not specify when they will begin.

“Given the demands of business and the trade unions, in reality, talks with Gazprom to renew supplies are inevitable,” Hristov told reporters.

The European Union country had been meeting more than 90% of its gas needs with Russian deliveries until April, when Gazprom cut supplies to Bulgaria over the previous government’s refusal to pay in roubles.

Its long-term contract with Gazprom expires at the end of 2022.

He said he did not expect easy and quick talks. “The situation with Gazprom is not rosy at all… We would obviously would have to turn to them now. The talks will be very hard and very difficult,” he told reporters.

Currently, the nation, which requires 3 billion cubic meters of gas annually, receives 1 bcm from Azerbaijan and purchases the remaining 2 bcm on the open market.

The Bulgarian interim government has also decided to seal a deal with U.S. gas company Cheniere for just one cargo of liquefied natural gas for October, saying it could not secure slots at LNG terminals at affordable prices for the other six cargos secured by the previous Cabinet.
