Bulgaria will be able to receive up to three million cubic metres of natural gas from Greece daily.
This becomes possible after the modernisation of the compressor station in the town of Petrich, which was unveiled officially on Monday.
The ceremony was attended by Bulgarian Prime Minister Boyko Borisov, Energy Minister Temenuzhka Petkova, executive director of Bulgartransgaz, Georgi Gegov, as well as representatives of local business.
Deputy Prime Minister Tomislav Donchev and US ambassador to Bulgaria, His Excellency Eric Rubin, were also invited to attend the ceremony.
The investment, which has been funded by the EU, amounts to 17 million euros and is expected to make Bulgaria more independent in terms of its energy supplies.
Through the modernized compressor station Bulgaria will be able to receive a third of its energy supplies from Greece.
