The Bulgarian Energy Holding and Russia's Gazprom signed the agreement for the establishment of a joint venture with equal participation, which will manage the Bulgarian stretch of the South Stream natural gas pipeline, Dnevnik daily reported. The registration procedure will be completed by November 2012. The company will accept the results of the feasibility study, which will follow the establishment of the JV, and will afterwards assign the design and the environmental impact assessment (EIA) before the investment proposal is being made. Afterwards, the joint venture will build, own and operate the gas pipeline. The establishment of the entity was envisaged in the project roadmap, signed on July 17, 2010. The South Stream is a joint project of Italy's Eni and Gazprom, envisaging transportation of Russian natural gas through the Black Sea to Bulgaria and further to Italy and southeastern and central Europe. It is due to be completed in 2015 and is estimated to cost EUR 25bn, much above the initially planned EUR 10bn. Gas supplies in the amount of 63bn cubic metres per year under the project are to start from the Beregovaya compressor station in Russia and reach Bulgaria through the Black Sea. The agreement for the establishment of the JV was signed during the visit of Russian PM Vladimir Putin. After talks with his Bulgarian counterpart Boiko Borissov, it emerged that the technical design of the Bulgarian nuclear power plant Belene on the Danube river will be ready by end-2010 , econ.bg reported. In February 2008, AtomStroyExport signed a EUR 4bn preliminary contract to build the plant and a few months ago requested an increase of the price by EUR 2.5-3.5bn. After talks with Putin, Borissov said the EUR 4bn price is neither final, nor real. Economy minister Traicho Traikov later on said at a news conference, that Russia offered a price of EUR 6.3bn, but added that for Bulgaria this price is not acceptable. In September 2009, field works on the nuclear plant were frozen after Germany's RWE withdrew from the project.
