The construction of the section of the Vertical Gas Corridor located on the territory of Bulgaria has entered its final phase of implementation. As announced on the official website of the Bulgarian Ministry of Energy, two projects within this initiative are scheduled to be put into operation by the end of 2026. The initiative connects gas infrastructure along the south–north axis and opens up opportunities for the transport of liquefied natural gas (LNG) to regional markets.
These projects will enable the transmission of LNG, including supplies from the United States, via Greece to Ukraine and countries of Central and Eastern Europe, further strengthening the diversification of supply sources and regional energy security.
Speaking at a ministerial meeting held in Washington, Bulgarian Minister of Energy Traycho Traykov stated that Bulgaria is the first country to have launched concrete construction works on the Vertical Gas Corridor, positioning itself as one of the key drivers of regional initiatives aimed at strengthening energy security.

As part of the project, activities are currently underway to increase capacity at key interconnection points, including Kulata/Sidirokastro on the border with Greece and Negru Voda/Kardam on the border with Romania. The Vertical Gas Corridor functions as an energy “highway” running from south to north, enabling the transport of up to 10 billion cubic meters of LNG annually to Ukraine and the wider region via the Negru Voda 1/Kardam interconnection point.
In the meantime, Bulgaria has applied for partial grant funding from the European Union’s Modernisation Fund. If approved, the funds would allow for the establishment of a competitive tariff structure, benefiting both domestic and regional users of the gas transmission network.
Additionally, during the course of next year, the commissioning of interconnector points near Stara Zagora and Komotini in Greece is planned, with increased capacity. Beyond their strategic role in diversifying supply sources, these projects are expected to provide greater flexibility in managing natural gas deliveries and facilitate easier access to new markets, according to the statement from the Bulgarian Ministry of Energy.
