The paper presents experimental investigation, calculations and analyzes of emission factors of low-quality domestic lignite from the Kolubara Basin, which is used for the operation of the Thermal Power Plant "Nikola Tesla". The studied lignite samples presented in this paper and their mutual comparison cover seven years of operation in the period 2012-2018. Standard analytical methods were used to determine the emission factor of lignite, including ultimate analysis, proximity analysis and determination of lower heating value. Based on the experimental results obtained, correlated dependencies of the emission factor of lignite were determined for the specified years and a comparison was made. From 2020, J.S.C. "Elektroprivreda Srbije", the operator of TPP "Nikola Tesla", imports coal of better quality, mixes it with Kolubara lignite and uses the mixture for firing the units of power plant B. A comparison was made between the lignite from Kolubara, which was offered for a long period of time, and the mixture with imported coal from last year. The change in the quality of domestic lignite, expressed as an emission factor, over time was presented together with the analysis of the change in the emission factor found for the coal blends used in recent years.
