The energy sector in Serbia

Serbia, with a population of around 6.9 million, satisfies most of its electricity demand from domestic production. Electricity production in Serbia relies around 70 per cent on low-quality lignite coal, causing serious pollution, while most of the remainder is generated in hydropower plants. Despite strong growth in wind power in recent years, in 2020 it still made up only 2.7 per cent of electricity generated.

The electricity market in Serbia is dominated by the state-owned power utility EPS (Elektroprivreda Srbije – Power Industry of Serbia), which owns all large generation capacities and supplies most consumers. 

Fossil fuel production 

Serbia’s coal reserves are mainly located in two main coal basins, Kolubara and Kostolac. The coal mines in Serbia are mostly owned and managed by subsidiaries of EPS, but another state-owned company also owns the troubled Resavica underground mines. 

The Kolubara Mining Basin provides around 75 per cent of the lignite used for EPS’ thermal generation. It produces 30 million tonnes of lignite annually on average, with 2021 being the least productive year at 27 million tonnes, which is supplied to the Nikola Tesla A and B, Kolubara A and Morava power plants, together producing more than 50 per cent of Serbia’s electricity.  

The Drmno mine near Kostolac provides the other 25 per cent, averaging more than 9 million tonnes. Its coal is used by the Kostolac A and B plants, and production is planned to expand to 12 million tonnes annually for the needs of the new Kostolac B3 unit. 

Serbia has produced oil and gas in small quantities since the mid-50s, but is heavily reliant on imports, mostly from Russia. 

Hydropower hassle 

No new large hydropower plants have been built for several years, although several are planned. As in other southeast European countries, a proliferation of small hydropower plants has provoked widespread public resistance as they are often sited in or near protected areas or other valuable areas.  

Inadequate planning and assessment of cumulative impacts means that they often cause a large amount of damage compared to the small amount of electricity they generate. By the end of 2021 around 131 newer small hydropower plants were online, but they generated only 0.9 per cent of Serbia’s electricity. Financiers of the plants are often hard to trace but include Austria’s Erste, Unicredit, the EIB and the EBRD. 

New coal still on the cards despite climate vulnerability 

As Serbia intends to join the EU, it should also be aiming for decarbonisation by 2050, in line with EU policy. However the EPS plans to remain locked-in to a carbon-intensive energy system, most notably through the construction of the 350 MW Kostolac B3 lignite power plant, which is ongoing as of early 2023. 

In 2021 hopeful signs appeared as Serbia cancelled the Kolubara B coal power plant project, but it was not removed from the country’s draft spatial plan. Nor were four other planned fossil fuel power plants: 

• Nikola Tesla B3 – 750 MW – lignite 
• Novi Kovin – 2 x 350 MW – lignite 
• Štavalj – 300 MW – lignite 
• CHP Novi Sad – 340 MW – gas 

Not only would this exacerbate climate change, but ironically Serbia’s coal mines have also suffered from its consequences. In May 2014 the Kolubara mines were turned into polluted lakes. Each of the four mines was flooded, two of them completely. In the biggest open-pit mine, Tamnava West, ten huge excavators used for mining were flooded, and six of them completely underwater.  

The Drmno mine also suffered serious flooding in 2014. During the May floods a heroic effort was mounted to save the mine, but between July and September of the same year more than 2 million cubic metres of water spilled into the mine, bringing with it around 800 000 cubic metres of sludge and mud, that engulfed mining machinery.

Renewable energy and energy efficiency 

Serbia narrowly missed its 2020 renewable energy target of 27 per cent of gross final energy consumption – in 2020 its share was 26.3 per cent. By the end of 2021, Serbia had 398 MW of wind power installed but only 12 MW of solar. In 2021 a new Law on Renewable Energy was approved, which moves Serbia to a market-based support scheme and should speed up solar installation in particular. 

With its traditional forms of generation not proving resilient to climate change, Serbia would do well to diversify its energy mix and work more on energy efficiency. Serbia has promising potential for renewable energy, but as with all the countries in the region, different sources put the exact figures at quite different levels, depending among other things on whether they use sustainability criteria. 

Serbia has significant potential for energy efficiency  and inefficient use of energy represents a major concern in the country. It has the second-highest energy intensity in the region, nearly four times as much as the EU average in 2020. Incentives to save energy are limited due to artificially low electricity prices but this is going to have to change in the coming years as Serbia integrates into the European electricity market.
