The Vertical Corridor, a regional gas initiative, is expanding its network into the Western Balkans, according to Offshore Energy. This expansion includes the participation of North Macedonia and Serbia, marking a significant development for the region's energy infrastructure.

The integration of these Western Balkan countries into the Vertical Corridor is expected to strengthen energy diversification. It aims to improve cross-border connectivity for gas supplies, as reported by Offshore Energy.

This initiative is also projected to enhance the security of gas supply. The expanded corridor will facilitate gas flows from Greece to various markets across Southeast and Central Europe, as stated in the source material.
