According to the Serbian business media outlet Parametar, the Bulgarian state-owned company Bulgargaz has received a 10-year license for wholesale natural gas supplies in Serbia, opening the door for yet another major regional player to compete for Serbian consumers.
As Parametar analyzed, the significance of this decision lies not merely in the emergence of yet another licensed company. Bulgargaz has its own procurement portfolio and access to gas infrastructure in several Central and Southeastern European countries.
The company already holds the necessary licenses and permits to trade and supply gas in Greece, Romania, Hungary, and Slovakia, and operates in Moldova through its subsidiary, Bulgargaz North.
Of particular importance to Serbia is the interconnector with Bulgaria, with a capacity of approximately 1.8 billion cubic meters per year. Via Bulgaria, the Serbian market can receive Azerbaijani gas, as well as LNG arriving in the region through Greek terminals.
Bulgargaz will potentially be able to offer large Serbian enterprises a comprehensive supply package—from LNG procurement and regasification to transportation through Bulgaria and delivery of gas to Serbia.
For now, however, the discussion is limited to obtaining a license. Bulgargaz has not yet announced any major contracts with Serbian consumers. Therefore, the key indicator of a genuine market entry will be the booking of cross-border capacity and the signing of the first contracts.
The Serbian gas market is formally open to competition, but in reality remains highly concentrated. According to the latest complete AERS data for 2024, the state-owned company Srbijagas accounted for about 78% of gas sales to end consumers, Novi Sad-Gas for about 3.9%, Yugorosgaz for 3.2%, and each of the remaining suppliers accounted for less than 2%.
At the same time, the market infrastructure is changing. There are three gas transmission system operators in Serbia: Transportgas Srbija, Gastrans, and Yugorosgaz-Transport. In 2026, Transportgas received an operating license, and Serbia joined the regional platform for booking gas transmission capacity, which should facilitate new suppliers’ access to cross-border routes.
The arrival of Bulgargaz does not in itself mean lower prices or a significant redistribution of the market. However, if the Bulgarian company begins to actually supply gas to Serbian industrial enterprises, the Serbia-Bulgaria interconnector will gradually transform from infrastructure for diversifying supplies into a tool for real competition among suppliers.
