About plants

The first biogas plant in Serbia was constructed in 1987. within Corporation PKB - Agricultural Combinate Belgrade.  This biogas plant was built on the pig farm Vizelj (producing 35,000 pigs per year), where wastewater was used for biogas production. Total investment was 1.2 million USD and biogas plant had been operational for 7 years, providing heat and electricity for the farm. Due to the problems with the import of the spare parts during the International sanctions against  Yugoslavia, facility stopped working in 1994.

Biogas market in Serbia started with significant development due to measures initiated by Republic of Serbia for purchasing of the total quantity of electricity produced from biogas (feed-in tariff) in 2009., with The Decree on Incentive Measures for Electricity Production from Renewable Energy Sources and Combined Heat and Power Production. Incentives, namely the purchase price, are defined depending on their installed power and for three categories: up to 0.2 MW (16 ceur per kWh), from 0.2 to 2 MW and over 2 MW (12.04 ceur per kWh). Biogas produces with privileged status got this electricity prices for period of 12 years.

In 2014. feed in tariffs, defined with Decree on Incentive Measures for Privileged Energy Producers, was between 12.31 and 15,66 ceur/kWh depending on their installed capacity. The last changes related to energy prices produced from biogas was introduced in 2016. and prices were calculated in following way: for plants with capacity lower than 2 MW - 18,333-1,111*plant capacity in MW; for plants with capacity between 2 and  5MW - 16,85-0,370*plant capacity in MW;and for plants with capacity above 5 MW eletricity prices were 15 Ceur / kWh.

The first biogas plant with privileged status in Serbia was constructed in 2011. Currently 22 biogas plants operate in Serbia with total installed capacity of 21 MW. Moreover, 28 biogas plants have temporary privileged status as energy produces with total capacity of 27,266 MW, which are expected to be operative in near future. With provision of temporary privileged status biogas plants are supposed to start with operation within next three years.

The largest biogas plant in Serbia operate in Alibunar, with total capacity of 3,6 MW.

The register with privileged energy producers, temporarily privileged energy producers and producers from renewable energy sources is available on following address of Ministry of Mining and Energy of Republic of Serbia:

From the beginning of GIZ DKTI Programme investors in biogas plants were actively supported. Technical assistance was firstly directed to education and trainings for biogas operators and investors. Most of the trainings were provided with engagement of German experts, together with several study tours to German biogas plants.

Germany is European leader in the field of biogas, with more then 10 000 constructed biogas plants. Moreover, feed in tariffs in Germany is provided for the period of 10 years, so the projects costs effectiveness is high. There are additional benefits for small biogas plants with capacity of 75 kW, which are using manure up to 35% as raw material. Biogas sector is also developed in United Kingdom and Italy.

Additional specific for Germany is concept of energy cooperative, where farmers work together with aim to provide required amount of raw material for common biogas plant. GIZ DKTI Programme promotes idea of energy cooperatives establishment in Serbia. Since size of average agricultural land in Serbia significantly decreased in the last 20 years, independent collection of required raw material is impossible. Thus, concept of energy cooperative could be beneficial in various ways.

The study on possibilities for establishment of energy cooperative in village Verusic, Subotica was prepared within GIZ DKTI Programme. The study ecomaps cooperation of 19 farmers, with total 500 ha of land and 1,055 livestock units. This cooperative could provide 3,450 t of manure, presenting the main raw material for biogas plant  together with silage. Considering 12 years of feed in tariffs for energy purchase and the use of heat for drying agricultural products, results shows that construction of biogas plant with capacity higher than 500 kWe is cost effective in this case. Also, project realisation will solve problem of waste in the farms, which will lead to reduction of GHG gasses. The project will influence on rural development and employment within the region as well.

Successfully realised projects

Čestereg

Construction of biogas plant in village Cesterg, Municipality of Vrbas, started in 2017. Biogas energy plant acquired privileged status as energy producers in 2018. The total capacity of plant is 637 MW in electricity and additional products are heat and organic fertilizer. As raw material biogas plant utilises maize silage, sorghum (300 ha) and manure (1,800 tons). From project idea to the realisation has passed only one year.

Botos

Biogas plant with capacity of 600 kWe was constructed in Botoš, Municipality of Zrenjanin. The Energy plant is producing heat and high-quality fertilizer beside electricity.

Produced electricity is being taken over by state-owned electric utility power company, currently with annual amount of 600 kWe. Secondary product from biogas plant is organic fertiliser, which is used for further agricultural needs.

Possibilities for usage of heat generated during production of electricity was investigated by GIZ DKTI Programme. Currently, generated heat is used for heating digestor, but there is additional heat which could be used for heating surrounded buildings.

One of possibilities for heat usage is heating public buildings in centre of Botoš. Possible connected buildings in mini heating grid would be kindergarten, primary school, municipal building, cultural centre, police station and sports hall.
