Transportgas Serbia LLC, based in Novi Sad, has initiated a study to optimize gas arrangements within the transport system. The technical specifications for the project highlight Serbia’s heavy reliance on energy imports in the natural gas sector, compounded by a decline in domestic gas production and a lack of significant new discoveries.
The completion of the Balkan Stream gas pipeline and the Nis-Dimitrovgrad interconnector has positioned Serbia as a key transit country for natural gas, facilitating access to new sources such as Azerbaijan. However, a comparative analysis of Russian and Azerbaijani gas reveals significant differences in quality and chemical composition, potentially impacting the functionality of the gas transportation system and affecting consumers across Serbia.
In response, regulatory amendments have been introduced to establish standards for the quality and chemical composition of natural gas entering the transport system. This includes specifications for gas received at the Kalotina-Dimitrovgrad entry/exit point, deviating from the previously established standards.
The study aims to analyze the process of blending different gas qualities to meet system requirements and consumer needs. It encompasses various segments of the transport system, including main gas pipelines and distribution networks, and evaluates the impact on major consumers such as industrial plants and heating facilities.
Additionally, the study assesses the potential installation of gas mixing equipment and analyzes the contractual implications of sourcing gas from Azerbaijan. The operator of the transport system is mandated to negotiate agreements on the working regime with neighboring operators and gas distributors, ensuring adherence to quality standards.
Gas expert Vojislav Vuletić emphasizes the importance of maintaining gas quality standards, noting that lower-quality gas could compromise system integrity. He underscores the necessity of ensuring that gas meets minimum methane content requirements and discusses the implications of deviations in the upper calorific value.
While acknowledging slight deviations in Azerbaijani gas quality specifications, Vuletić emphasizes the importance of upholding quality standards to safeguard system reliability and consumer interests.
