The first capacity auction for the revamped Vertical Gas Corridor has cleared more than 45% of the total available volume at the Sidirokastro interconnector, according to the Greek gas transmission operator.

The result signals robust commercial interest in the pipeline’s role as the primary export gateway to Bulgaria and the wider Southeast European market.

The high take-up rate underscores the growing reliance on liquefied natural gas (LNG) to diversify supply sources in the Balkans.

Sidirokastro serves as the critical node for routing gas from Greece’s Revithoussa LNG terminal into neighboring countries, effectively turning the region into a distribution hub for imported gas.

This development reinforces the strategic importance of the corridor in reducing dependency on traditional pipeline supplies.

Market participants view the auction results as a positive indicator for the viability of Greece’s energy infrastructure investments.
