ICGB launches market demand assessment for capacity expansion of the IGB pipeline
The process includes a non-binding and a binding phase to determine the market feasibility of the capacity increase project targeting expansion from 3 bcm/y to 5 bcm/y
ICGB, the independent operator of the Greece–Bulgaria interconnector (IGB), is launching the non-binding phase of a process to assess market interest in expanding the pipeline’s capacity. The procedure is conducted under Regulation (EU) 2017/459 (NC CAM) and marks a key step toward reinforcing long-term energy security in the region.
The assessment, carried out in close coordination with the adjacent transmission system operators, will determine the feasibility of increasing IGB’s technical capacity from 3 to up to 5 bcm/year. Interested market participants are invited to submit their non-binding demand indications by September 1, 2025. All relevant documents and participation guidelines are available at https://www.icgb.eu/transparency/public-consultations/.
“Expanding IGB’s capacity is a strategic move for the entire region,” said ICGB’s Executive Officers George Satlas and Teodora Georgieva. “As the first route for diversified natural gas supplies to Bulgaria, IGB plays a critical role in ensuring secure, sustainable energy for Southeast Europe. We remain firmly committed to this process and to delivering enhanced connectivity and resilience across the region with our partners”, they noted.
Following this phase, ICGB and adjacent TSOs will compile Demand Assessment Reports for each interconnection point. These will form the basis for possible future steps, including project proposals, consultations, and regulatory approval.
