Bulgaria and Russian energy giant Gazprom have agreed on technical aspects of the Bulgarian stretch of the South Stream gas pipeline.
Gazprom CEO Alexander Medvedev signed a protocol on the technical specifications in Sofia on August 27.
In 2010, the state-owned Bulgarian Energy Holding and Gazprom set up a 50-50 joint venture to plan, build, and operate the Bulgarian stretch of the 3,600-kilometer South Stream pipeline.
The link, due to pass under the Black Sea, will carry Russian gas to Europe and is due to be fully operational in 2018.
Also on August 27, Bulgarian Minister for Economy and Energy Deyan Dobrev announced that Sofia had signed a deal with Gazprom in which Bulgaria would get an 11 percent discount on Russian gas from April to the start of next year.
