Bulgaria will go ahead with plans to spend 1.4 billion euros ($1.59 billion) to build a new gas link to Turkey to transport Russian gas from the TurkStream pipeline to Europe, bypassing Ukraine to the south.
Bulgarian lawmakers gave the green light to the state gas company Bulgartransgaz to launch tenders to build a new 484-km gas link that will carry mainly Russian natural gas.
TurkStream is part of the Kremlin's plans to bypass Ukraine, currently the main transit route for Russian gas to Europe, and strengthen its position in the European market.
Gazprom said on Friday it was considering booking capacity, which would effectively ensure that the gas Russia plans to send to Europe through its Black Sea pipeline will pass through its land.
The news comes at a time of increased tensions between Russia and Ukraine, and Sofia is concerned that the conflict may once again put the brakes on Russia's plans to ship gas through Bulgaria to Europe, bypassing Kiev.
"What follows from now on is a strict observation of European Union rules and procedures, so that we can eliminate all eventual mistakes that in the past have led to the cancellation of South Stream," Energy Minister Temenuzhka Petkova said.
Bulgaria is still smarting from the 2014 cancellation of Russia's plan to bring gas to its shores with its South Stream pipeline. The project, which had promised the Balkan country on the European Union's periphery money and clout, was dropped by Russia after it blamed opposition from Brussels.
At present, Gazprom transports about 14 billion of cubic meters (bcm) of gas a year to Turkey via Bulgaria through a contract that runs through 2030.
Bulgaria is ready to give up on its take-or-pay option in the current contract if it gets a new 20-year deal to transport Russian gas through the new pipeline and says its net profit for the period could be as much as 2.2 billion euros.
Brussels has been concerned that Bulgaria may opt to simply send Russian gas onto Europe to earn transit fees rather than allowing it to be traded at its planned Balkan Gas Hub, cementing its almost complete dependence on Gazprom.
Some energy experts have also voiced concerns that Bulgaria is rushing too quickly with projects linked to Russian gas and dragging its feet with plans to develop gas links that would allow diversification.
In a bid to ease such concerns, Sofia says the new pipeline will be built in line with EU energy rules.
