As the EU Carbon Border Adjustment Mechanism moves from design into practical trade impact, electricity flows from Southeast Europe are being re-priced through embedded emissions. For Serbia, where generation is still dominated by lignite, CBAM is functioning as a carbon price barrier that makes coal-based power harder to sell into the EU market. That shift is pushing exporters and policymakers to define what “CBAM-compliant electricity” would look like in operational terms—power with sufficiently low carbon intensity to remain competitive.
Carbon pricing meets electricity trade economics
Serbia’s system is anchored in coal resources, with Elektroprivreda Srbije operating roughly 4.4 GW of lignite-fired capacity. The fleet is concentrated in large thermal plants including Nikola Tesla A and B and Kostolac B, which supply most baseload electricity and have benefited from relatively low domestic generation costs because lignite is mined locally. Under CBAM conditions for electricity exported into the EU market, however, lignite combustion emissions translate directly into a financial cost tied to the EU carbon price.
Lignite-based generation typically emits more than 1 tonne of CO2 per MWh of electricity produced. With EU carbon allowances trading around €70–90 per tonne of CO2, the implicit carbon cost of Serbian coal-based electricity can exceed €70–80 per MWh. Industry stakeholders say this magnitude is enough to make exports economically uncompetitive, even when domestic fuel costs remain comparatively low.
What “CBAM-compliant electricity” implies for exporters
Developing CBAM-compliant electricity therefore hinges on reducing the carbon intensity of the volumes offered for export. In practical portfolio terms, that means shifting away from coal toward low-carbon generation sources such as hydropower, wind, solar and potentially energy storage. The regulatory relevance is straightforward: lower embedded emissions reduce the carbon-related cost pressure created by EU carbon pricing.
Serbia already has a starting point through hydropower assets that are expected to carry negligible carbon footprint for export purposes. The country operates roughly 3 GW of hydropower capacity, including major facilities along the Danube such as Djerdap I and Djerdap II, which together represent some of the largest hydropower assets in Southeast Europe. Hydropower can therefore support CBAM-compliant export positioning when it is available at sufficient output levels.
Hydrology limits baseload exports and raises the need for renewables
Despite its role in lowering embedded emissions, hydropower alone cannot reliably cover export volumes needed to sustain Serbia’s historical trading position. Hydrological variability causes generation levels to fluctuate significantly from year to year, and dry seasons can reduce output sharply. When that happens, Serbia tends to rely more heavily on coal generation—reintroducing higher embedded emissions into the export mix.
The next step in building CBAM-aligned export volumes is expanding renewable capacity beyond existing hydropower. Serbia has started introducing renewable energy auctions intended to stimulate new wind and solar projects, with several auctions already launched covering several hundred megawatts of capacity. Project pipelines suggest wind and solar capacity could grow rapidly over the next decade.
From wind and solar build-out to certification and storage
Wind resources are described as particularly promising in Vojvodina and eastern Serbia, where several large wind farms are already operating. Solar potential is also substantial, especially in central and southern parts of the country where irradiation levels are higher. Over time, the long-term objective is to create a portfolio of renewable generation assets specifically earmarked for export into EU markets.
To support trade compliance expectations around origin and emissions performance, such electricity could be bundled with guarantees of origin certifying that exported power originates from renewable sources and carries minimal carbon emissions. As variable renewables increase, energy storage becomes a complementary requirement: battery storage or pumped hydro storage can smooth fluctuations and help keep exports reliable and predictable.
Investment scale and industrial knock-on effects
Financing this transition requires substantial investment across renewable projects, transmission upgrades and storage facilities, described as a multi-billion-euro investment cycle. International financial institutions, European development banks and private investors are expected to play major roles in funding the infrastructure needed for a lower-carbon export portfolio.
The implications extend beyond electricity trading economics. Energy-intensive manufacturers such as steel and aluminium producers increasingly require low-carbon electricity to maintain competitiveness in EU markets, meaning renewable expansion can support both export objectives and industrial decarbonisation efforts within sectors exposed to EU climate policy pressures.
Analytical synthesis: CBAM pressure drives a shift in power portfolios
CBAM-linked carbon pricing is reshaping how Serbian exporters manage embedded emissions in cross-border electricity sales. With lignite emissions typically above 1 tonne of CO2 per MWh and an EU allowance price around €70–90 per tonne of CO2 translating into more than €70–80 per MWh in implicit carbon cost, coal-based exports face clear competitiveness constraints. Serbia’s response—scaling hydropower-backed renewables through auction-driven wind and solar growth, using guarantees of origin for certified low-carbon supply, and adding storage such as planned Bistrica pumped storage—aims to maintain regional supplier roles while aligning exported volumes with EU climate policy requirements.
