January trading on SEEPEX showed a day-ahead market clearing of 404,970.3 MWh, with an average daily baseload price of €118.13/MWh and a peak of €136.27/MWh. The month’s most stressed day recorded €293.84/MWh in peak and €228.29/MWh in baseload terms. The figures describe a winter pattern, while the risk profile shifted away from the day-ahead screen toward two additional pricing layers affecting Serbia’s cross-border and system settlement economics.
In Serbia, the balancing and imbalance layer operated by EMS is described as the point where physical system stress is priced rather than only reflected. The SEEPEX hourly price pattern indicates that stress concentrates as prices move from a morning shoulder into an evening ramp. Average hourly prices were around €166.55/MWh at hour 17 and €178.58/MWh at hour 18 before easing. The same hours are linked to conditions where schedules are hardest to follow.
EMS balancing settlement mechanics and January price shape
The EMS imbalance settlement approach is presented as relevant to trading strategy because settlement depends on a weighted price of activated resources. The settlement outcome is administratively bounded, including rules that settlement cannot be negative and can be capped relative to the most expensive upward activation in the interval. With this structure, imbalance exposure is described as becoming more than a limited penalty once expensive upward energy is activated. The effect is associated with short positions being pulled into the same pricing dynamics when upward activation drives settlement levels.
A Serbia-specific quantification uses EMS-reported reference values rather than a full January imbalance time series. EMS discloses a reference “balancing energy price” for 2026 of 154.174 EUR/MWh, characterized as a regulatory-weighted anchor rather than a January average. That reference is positioned above the €118.13/MWh January baseload day-ahead average, indicating that balancing value can sit structurally higher than day-ahead baseload levels.
The economic envelope for January is described as depending on how much energy is settled in imbalance instead of remaining within scheduled volumes. A scenario for a well-functioning control area assumes net activated balancing or imbalance exposure in the low single digits of day-ahead cleared volume due to forecast error, outages, ramp limits, and cross-border adjustments. Using this framing, if net repriced balancing or imbalance energy equals 2% of January’s SEEPEX-cleared volume, it corresponds to about 8,099 MWh against 404,970.3 MWh. The implied monthly transfer is estimated at about €0.40 million, €0.81 million, or €1.21 million, depending on whether the premium over day-ahead baseload reference is €50/MWh, €100/MWh, or €150/MWh.
CBAM-linked carbon add-on for Serbia’s EU-facing electricity trades
The second layer described for Serbia’s 2026 electricity economics is CBAM-adjusted pricing for cross-border sales into the EU. CBAM moved into its definitive regime from 1 January 2026, with certificate pricing linked to EU ETS allowance prices expressed in €/tCO₂ and averaged quarterly during 2026. For electricity reporting, the framework referenced in the source text is evolving toward default emission values based on overall emission intensity of the exporting power system rather than assumptions limited to fossil generation alone.
The carbon policy change is presented as affecting Serbia because it converts “national grid carbon intensity” into basis risk for cross-border electricity sales into the EU when low-carbon attribution relies on documentation that may not be recognized or auditable. Quantification starts with an EU carbon price anchor: EU carbon permits were reported around €81.35/tCO₂ on 9 February 2026. A second anchor uses Serbia’s grid emissions intensity, placed in a stress-testing band of about 0.67–1.05 tCO₂/MWh, reflecting coal-dominant generation with hydro providing an offset described as meaningful but insufficient.
Multiplying these anchors produces a CBAM-style carbon value embedded in 1 MWh exported under default or system-average logic. At 0.67 tCO₂/MWh, the carbon value is about €54.5/MWh; at 1.05 tCO₂/MWh, it is about €85.4/MWh. The carbon add-on magnitude is described as large enough to change trade economics when attribution is conservative or documentation is weak.
Interaction with SEEPEX prices during evening ramps
The source text places the carbon add-on alongside observed SEEPEX economics for January baseload pricing. With January baseload at €118.13/MWh, adding the carbon value range yields an EU-delivered “CBAM-adjusted” level of roughly €173–203/MWh. In hours when Serbia most seeks to monetize exports—identified as evening ramps—January averaged around €166.55–178.58/MWh. Under the same CBAM-style addition, those hours are estimated at roughly €221–264/MWh, before congestion, losses, and corridor-specific spreads.
A tradeoff is described between selling into the EU with verified low-carbon intensity versus relying on default values when documentation does not meet acceptance criteria. If exporters can prove low-carbon intensity through accepted auditable instruments and credible measurement, sales are described as closer to physical price spreads with a tighter carbon basis. If they cannot, the carbon basis becomes a structural haircut in the range of roughly €55–85/MWh. The source text links this shift to changes in contracting terms and value allocation away from short-term arbitrage toward longer-term structured delivery with embedded certification and traceability.
Taken together, the source text characterizes January’s Serbia-only risk trend as involving both balancing-layer exposure tied to timing and CBAM-linked economic drag tied to attribution for EU-facing trades. It describes balancing penalties as concentrated into evening ramps and capable of moving high six-figure to low seven-figure value amounts within a winter month from only a few percent of volume repriced through imbalance settlement mechanisms.
The CBAM layer is described as producing potential economic drag on EU-facing trades unless carbon profiles are credibly documented, using the stated add-on range derived from EUA levels and Serbia grid emissions intensity assumptions at current permit prices referenced in February 2026 reporting.
