From 1 January 2026, electricity imported into the EU from Energy Community Contracting Parties is explicitly within CBAM’s scope, creating an administrative and financial layer on cross-border power flows that did not previously exist. For Serbia, this matters in a very specific way: the CBAM exposure on electricity is not driven by what a single generator claims, but by what the importing side must declare and pay for based on embedded emissions and the CBAM electricity rules; at the same time, Serbia’s domestic electricity mix still leaves most industrial consumption structurally tied to a high-carbon residual mix unless ring-fenced with credible instruments and supply arrangements.
Serbia’s own official residual-mix reporting for 2024 illustrates the constraint. The structure of electricity produced in Serbia is shown as hydropower 28.97%, wind 3.89%, solar 0.35%, and biomass 0.85%, with the remainder dominated by fossil generation (the same report is explicit about the production structure by source). That is the backdrop against which both electricity exporters and CBAM-exposed manufacturers will be judged in commercial negotiations: if the system is mostly coal-linked in the residual mix, then the default embedded electricity emissions for most grid-supplied MWh are difficult to “wish away” with marketing language. The result is that Serbia’s electricity export margin to EU hubs becomes more sensitive to carbon pricing, and Serbia’s industrial exports become more sensitive to electricity-linked embedded emissions, even when the exported product itself is not electricity.
Electricity exporters: what changes under CBAM in practical terms
The main mechanical change is that CBAM turns the carbon intensity of exported electricity into a monetised border cost for EU importers. The Energy Community’s CBAM materials describe that from 1 January 2026 electricity imports from Contracting Parties to the EU are subject to CBAM obligations. The European Commission’s CBAM Q&A for late 2025 also addresses electricity-related application from 1 January 2026, underscoring that the electricity channel is treated as a live compliance item rather than a distant future phase.
In Serbia’s case, the economic implication is that exported MWh become a “two-part price” when the counterparty is EU-based: the energy price plus a carbon adjustment that is effectively indexed to EU ETS conditions and to the calculated embedded emissions. In practice, that pushes three behaviours into the market.
First, export pricing becomes more conditional. The more the importing counterparty expects CBAM certificate costs to rise or volatility to persist, the more they will seek contractual pass-through or margin protection. That tends to reduce the attractiveness of Serbia-origin marginal exports in periods when EU interconnectors have alternatives.
Second, the value of demonstrably low-carbon electricity attributes increases, because the gap between low-carbon and high-carbon MWh is no longer only reputational; it becomes a cash difference. This is where Serbia’s domestic instruments matter: Guarantees of Origin (GOs) and residual-mix accounting are the language EU counterparties will understand.
Third, electricity exporters in Serbia face a strategic question about where to allocate scarce low-carbon volumes. If low-carbon attributes are limited, they can be sold at a premium (sometimes implicitly) either to domestic industrial off-takers trying to protect CBAM-exposed exports, or to cross-border buyers. That allocation decision will increasingly be commercial rather than political.
RES producers: CBAM does not tax them directly, but it changes the value of what they sell
Renewable producers in Serbia are not CBAM declarants, yet CBAM changes their revenue stack because it changes who is willing to pay for long-term green supply and credible attributes. Two parts of the Serbian market architecture are now doing heavy lifting.
The first is the auction/CfD pipeline. Serbia’s second renewables auction was structured around a total quota of 424.8 MW, including 300 MW wind and 124.8 MW solar, with 15-year contracts for difference as the stabilising mechanism. The oversubscription in that round signals a supply response, but from an industrial CBAM viewpoint the key issue is timing and deliverability: announced quotas do not instantly translate into deliverable 24/7 green electricity for heavy industry, because grid connection schedules, balancing arrangements, and commissioning sequences determine when MWh actually arrive.
The second is the GO and disclosure framework, which determines whether an industrial buyer can credibly claim lower-carbon electricity and defend it in due diligence. Serbia’s national GO registry statistics for 2024 show 55 market participants and 41 production units registered, with 2,405,275 GOs issued for electricity produced and 2,447,795 GOs cancelled for electricity consumption. Those numbers matter because they indicate an active attribute market, but they also hint at the core Serbian constraint: once industrial demand for “credible green” grows faster than domestic renewable generation, the attribute market tightens and the economics of corporate PPAs and self-supply improve.
The heavy-industry exporter problem: CBAM is forcing an electricity strategy, not only a reporting strategy
For CBAM-exposed Serbian exporters, the most difficult part is not filling in templates; it is that electricity is one of the dominant drivers of embedded emissions in many industrial processes and supply chains. If a steel, cement, aluminium processing, chemicals, or metals value chain is powered mainly by lignite-linked grid electricity, the exporter’s delivered carbon intensity can become structurally uncompetitive as CBAM certificate costs embed into EU buyer pricing decisions. This is why the commercial conversation is increasingly shifting from “How do we report?” to “How do we lock in low-carbon power at scale?”
The uncomfortable truth is that Serbia does not currently have enough low-carbon electricity to satisfy every CBAM-affected producer/exporter with high-quality, defendable claims on a 24/7 basis. The 2024 production structure in the residual-mix report makes that clear: solar 0.35% and wind 3.89% are still small relative to the scale of industrial load; hydropower is meaningful at 28.97%, but it is already system-integrated and seasonally variable. Even if every industrial exporter “wants green,” they cannot all simultaneously rely on the same scarce incremental clean volumes without driving a scarcity premium, creating reputational risk around double counting, or defaulting back to the system residual mix.
That scarcity is exactly what makes self-supply and long-term contracting economically rational. In markets where green power is abundant, corporate PPAs are often a price hedge. In Serbia, they are increasingly a competitiveness hedge.
The diversification opportunity: Can Serbian heavy industry build or contract its own green electricity?
Yes, but only if it is approached as a bankable infrastructure program rather than an ESG add-on, and only if companies accept that “own green electricity” comes in tiers of credibility and operational impact.
The first tier is behind-the-meter or proximate generation. Industrial sites with available land or rooftops can deploy on-site solar and reduce net grid draw during daylight hours. This rarely decarbonises the full load profile, but it measurably reduces purchased electricity volumes and provides a tangible emissions reduction lever that can be documented. The limitation is obvious: most heavy industry runs continuously, while solar is intermittent.
The second tier is corporate PPAs with Serbian wind/solar portfolios, designed to deliver volume over the year and to allocate GOs transparently. Serbian industry bodies and market commentary have increasingly framed PPAs as long-term instruments, typically 10–25 years, that provide price predictability and allow buyers to hedge against volatility while securing a cleaner attribute stack. The CBAM twist is that the value of the PPA is no longer only the electricity price; it is also the exporter’s ability to demonstrate a lower-carbon electricity input into products sold to EU customers.
The third tier is building dedicated renewable capacity (directly or via an SPV) combined with contractual allocation of output to the industrial off-taker. In practice this looks like “captive renewables” even if grid-connected. Here, Serbia’s auction pipeline is relevant: it is expanding the pool of projects that can be financed, built, and then contracted with industrial off-takers, but the pace at which those MW convert into stable deliverable MWh will determine how quickly heavy industry can scale “own green power.”
The missing piece for most exporters is firming. A steel mill or major cement plant cannot run on intermittent supply without financial and physical balancing arrangements. That does not necessarily require owning batteries on day one, but it does require structuring supply so that the industrial buyer can claim credible annual matching, manage profile risk, and avoid being forced into a high-carbon residual mix at the worst commercial moments. This is where the market is likely to evolve: wind-plus-solar portfolios, contracted balancing, storage added later, and increasingly sophisticated accounting around attributes.
What this means for electricity exports out of Serbia
If Serbia’s renewable build-out accelerates and the attribute system remains credible, a portion of Serbian cross-border electricity could gradually re-price from being “volume exports that ride interconnector spreads” to being “structured low-carbon exports” that command better resilience under CBAM. But until the renewable share grows materially beyond today’s low wind and solar base, the more probable near-term outcome is that CBAM raises friction for Serbian electricity exports to the EU whenever the marginal export MWh is assumed to carry coal-linked emissions.
The key Serbia question: Can heavy industry realistically decarbonise through electricity alone?
Electricity is necessary but not sufficient. The best near-term competitiveness move for CBAM-affected Serbian exporters is to reduce the electricity-linked portion of embedded emissions through a combination of PPAs and self-supply, because that lever can move within the 2026–2028 window. However, some sectors also have process emissions (cement clinker chemistry is the classic case) that require deeper technical measures beyond electricity procurement. The strategic point remains: without credible access to low-carbon electricity at scale, Serbia’s exporters will struggle to defend a “green” positioning with EU counterparties, and Serbia’s electricity exporters will see a tighter margin envelope on EU-facing flows.
