A cooperation contract between Greece's Public Gas Corporation (DEPA) and the Bulgarian Bulgargaz company on the mutual coverage of possible shortages with natural gas due to extraordinary conditions, has been signed in Sofia by DEPA's president and managing director Haris Sahinis and Dimitar Gogov, the managing director of Bulgargaz.

According to the contract's terms, DEPA will be procuring natural gas from Bulgargaz for the coverage of extraordinary needs of the Greek market and correspondingly it will supply the Bulgarian company when similar needs appear in the Bulgarian market.

Another term foresees that the supplying of the Bulgarian network by DEPA will be taking place provided that the smooth supplying of the Greek market is not upset.

DEPA and Bulgargaz are already cooperating for the construction of the Greece-Bulgaria (IGB) pipeline, a project that is expected to begin in the last quarter of 2012.
