Glavbolgarstroy to Execute Key Sections of a Strategic Energy Project

One of the most ambitious energy initiatives in the region—the construction of the "Vertical Gas Corridor"—is entering its final stage of preparation. The commencement of actual construction along the routes connecting Greece, Bulgaria, and Romania is expected soon, forming a new gas axis that will be crucial for Europe's energy security.

Glavbolgarstroy has been selected as the contractor for two of the project’s lots. Preparatory work is progressing at full speed, with the delivery of essential pipeline materials already underway.

Key Construction Activities

At the southern entry point near Kulata (Kulata-Kresna looping section), intensive preparations are being made for the construction of a DN 700 gas pipeline extending to Kresna. Once completed, this expansion will increase transport capacity from 2.3 to 3.5 billion cubic meters per year—an important step toward diversifying gas supply sources.

To the north, along the Rupcha-Vetrino axis, an expansion project is in progress to double the transmission capacity to Romania—from 5 to 10 billion cubic meters annually. This development will position Bulgaria as a key transit hub between Southern and Central Europe.

Infrastructure & Logistics

The first batch of pipeline materials has already arrived at Burgas West Port. During his visit, Minister Zhecho Stankov stated:
"The Vertical Gas Corridor will yield substantial transit revenues and ensure stable gas supplies for our country."

Ilia Karabadzhakov, CEO of GBS Energy Solutions, confirmed that all materials meet the highest international standards. He also announced that the welding process for the Rupcha-Vetrino pipeline will be carried out in partnership with CRC Evans, a global leader in automated pipeline welding.

The pipes, featuring factory-applied internal and external insulation, are being delivered via a precise logistics operation from India through Kandla Port, the Suez Canal, and the Turkish straits to Burgas. Over the next 20 days, they will be distributed across seven temporary construction bases along the route. With a strict schedule in place, dozens of trucks will transport equipment and materials daily. Further deliveries of equipment are expected in the coming months to support the full execution of the project.

The main construction activities on the gas routes will commence within weeks. Given the challenging terrain and stringent safety and environmental requirements, the project presents significant technical demands. However, the objective remains clear—Bulgaria is taking a decisive step toward enhancing its energy security and reinforcing its strategic position on Europe’s gas supply map.
