The implementation of the Carbon Border Adjustment Mechanism (CBAM) is significantly altering the dynamics of electricity trading in Southeast Europe, particularly for Serbia. The country’s electricity generation is predominantly reliant on lignite-fired plants operated by Elektroprivreda Srbije (EPS). With CBAM in place, a clear distinction emerges between carbon-intensive electricity and low-carbon alternatives that can penetrate EU markets without incurring substantial costs.
Under the provisions of CBAM, imported electricity into the EU incurs an embedded carbon cost that correlates with the EU carbon price. Lignite, which is Serbia’s primary energy source, typically results in emissions close to 1 tonne of CO₂ per MWh. Consequently, coal-based electricity exports from Serbia face an embedded carbon cost estimated between €70 and €80 per MWh, reflecting current EU carbon allowances trading at approximately €70–90 per tonne. This financial burden places Serbian coal electricity at a competitive disadvantage within EU wholesale markets, where prices frequently range from €70 to €120 per MWh.
This structural barrier has already influenced trading patterns, rendering lignite-generated electricity economically unviable for export to the EU under standard market conditions. As a result, coal-based electricity exports from Serbia have diminished significantly.
Conversely, this same mechanism that restricts carbon-heavy exports simultaneously opens avenues for low-carbon electricity production. Power generated from renewable sources—such as hydropower, wind, and solar—can enter the EU market without incurring the penalties associated with CBAM. This category of electricity is increasingly recognized as CBAM-compliant.
Serbia is well-positioned to capitalize on this shift, boasting approximately 3 GW of hydropower capacity. The Djerdap I and Djerdap II hydroelectric plants on the Danube River are key contributors to the nation’s low-carbon energy output. Electricity produced from these facilities has minimal carbon intensity and thus faces negligible CBAM penalties when exported to the EU.
However, the variability of hydropower generation due to fluctuating rainfall necessitates an expansion of Serbia’s renewable energy portfolio to ensure a consistent supply of CBAM-compliant electricity. Wind and solar initiatives are becoming integral components of Serbia’s strategy for exporting electricity.
Recent renewable energy auctions have initiated new project developments, particularly in northern and eastern Serbia where wind conditions are favorable and transmission infrastructure is accessible. Solar energy projects are also gaining momentum in central and southern regions of the country due to higher solar irradiation levels.
The financial viability of these renewable projects is increasingly promising within the framework established by CBAM. Since renewable electricity generates negligible carbon emissions, it can be marketed in EU markets without facing the carbon penalties applied to coal-based power. This situation effectively creates a carbon price premium for Serbian renewable electricity exports.
This premium arises because renewable producers compete in markets where coal-based electricity must account for its carbon costs. Consequently, renewable energy generated in Serbia stands to be more competitive than coal-based alternatives from within the same system.
The evolving landscape presents new commercial opportunities for private renewable producers in Serbia. Historically dominated by EPS, which manages most generation capacity and transmission coordination, the Serbian electricity market is now witnessing independent producers seeking alternative revenue streams through potential exports to EU markets via cross-border trading platforms or bilateral agreements with European buyers focused on low-carbon energy supplies.
As demand for certified low-carbon electricity rises among European utilities and industrial firms—driven by climate policies and corporate decarbonization goals—the cost differential between carbon-intensive and low-carbon power continues to widen. This trend encourages European buyers to prioritize imports of renewable energy.
Private renewable producers could leverage this demand by securing export contracts with European partners through various mechanisms. One avenue involves physical exports via regional exchanges or bilateral agreements, allowing Serbian renewable energy to reach consumers across interconnected markets like Hungary, Romania, or Croatia.
Long-term cross-border power purchase agreements represent another potential pathway. Companies committed to decarbonization are increasingly looking for reliable sources of renewable energy from regions rich in such resources, positioning Serbia’s wind and solar capabilities as attractive options for long-term contracts with EU industrial stakeholders.
A third model involves guarantees of origin certificates that authenticate the renewable nature of exported electricity, enhancing its value in integrated grids where buyers can claim low-carbon consumption even when physical flows mix with other sources.
The success of these initiatives will hinge on various factors including fluctuations in wholesale electricity prices across Central Europe influenced by gas prices and weather conditions affecting renewable generation levels. However, with coal-based competition diminished due to CBAM, the relative value of Serbian renewable exports is poised to increase significantly.
For instance, if average wholesale prices in the EU hover around €90 per MWh while coal-based exports incur a CBAM penalty of approximately €75 per MWh, Serbian-produced renewable energy could become substantially more attractive in comparison.
This scenario incentivizes private investors to focus on developing renewable projects tailored for export purposes. By establishing wind or solar farms connected to Serbia’s transmission network, investors can target markets where higher prices and carbon premiums prevail.
Energy storage solutions will play a crucial role in facilitating this export strategy by balancing fluctuations in renewable production against varying demand throughout the day. Storage technologies such as battery systems or pumped hydro can stabilize export flows and enable sales during peak pricing periods.
The planned Bistrica pumped storage hydropower project aims to enhance large-scale storage capabilities essential for balancing renewable generation while supporting cross-border trading efforts. Such infrastructure improvements are vital for ensuring reliable exports of renewable energy and augmenting their commercial viability.
The changes brought about by CBAM will not only impact Serbia but could also reshape regional power markets across Southeast Europe. As coal-based generation becomes less competitive within EU frameworks, trading patterns may evolve based on carbon intensity metrics.
Countries heavily reliant on coal within the Western Balkans may increasingly engage in intra-regional trading while those rich in renewables strengthen connections with EU markets. Nations like Albania and Montenegro could emerge as pivotal players in cross-border trading networks due to their hydropower resources.
For Serbia, achieving a balance between its traditional coal generation capacity and emerging low-carbon economic models will be critical during this transition phase. While coal plants will remain vital for domestic supply stability initially, expanding renewable generation capabilities could gradually position Serbia as a key supplier of CBAM-compliant electricity for European markets.
This transition will necessitate substantial investments in renewable infrastructure along with enhancements to transmission networks and energy storage systems. Regulatory reforms will also be essential to facilitate easier access for independent power producers aiming at export opportunities.
If these prerequisites are fulfilled, private producers of renewable energy in Serbia stand poised to benefit significantly from CBAM’s introduction. What initially seemed like an obstacle may ultimately serve as a transformative force within the region’s electricity trading landscape while accelerating advancements in low-carbon power generation.
