In October, Dobrev said the Bulgarian section of the gas interconnector, planned to be launched in 2014, is expected to cost 60 million euro ($78 million).
The interconnector will stretch for 50 kilometres in Bulgaria and 100 kilometres in Serbia. It is expected to carry between 1.8 billion and 5.0 billion cubic metres of natural gas a year in either direction.
