The pipeline will provide gas supply from the Turkey – Greece – Italy Interconnection Pipeline, which imports gas from the Caspian region and the Middle East to Bulgaria and the Balkan countries.

The pipeline will have a capacity to transport between 3 and 5 Bcm/a and is due to come into operation in 2013.

IGI Poseidon – owned jointly by Greek energy company DEPA and Italian energy company Edison International Holdings – and Bulgaria Energy Holdings both hold a 50 per cent interest in the pipeline project.
