Montenegro’s direct electricity link to Italy is operated through the transmission-system arrangements of CGES and Italy’s Terna. Terna lists the Montenegro–Italy high-voltage direct-current interconnector at 445 kilometres in length and 600 MW in capacity in its end-2025 geographical overview. The connection expands trading opportunities for Montenegro’s electricity system, which includes hydropower, wind and coal-fired generation. Its technical capacity does not ensure that commercial transmission capacity will be available in every hour.
Electricity imported into the EU falls under CBAM unless a legal exception applies. The European Commission published a Q3 2026 CBAM certificate price of €82.32 per tonne of CO₂ equivalent. For electricity, liability depends on official default emissions measured in tonnes of CO₂ equivalent per megawatt-hour or on verified actual emissions under narrowly defined conditions.
Evidence needed for CBAM claims on wind-origin electricity
An exporter seeking to claim that electricity originated from a Montenegrin wind farm must provide documentation covering the required power purchase agreement (PPA). The claim also requires grid and transmission evidence, hourly matching, and verification. The generation technology alone is not sufficient for demonstrating eligibility for the relevant carbon-accounting treatment.
A wind or solar project may sell electricity to a domestic buyer, regional trading company or retailer that subsequently delivers power towards Italy. While such arrangements can be commercially viable under ordinary electricity-market rules, CBAM provisions for actual emissions add further requirements. These include a qualifying contractual relationship between the EU authorised declarant and an identified non-EU generator.
The additional requirements also include evidence that accepted cross-border capacity nominations correspond to electricity generation over intervals of no longer than one hour. The European Commission’s COM(2025)989 proposal would allow certain intermediary PPA arrangements where the contractual chain can be verified. The proposal has not been adopted, leaving 2026 business plans that assume broad access to actual-emissions treatment facing regulatory and financial uncertainty.
How default emissions affect export economics
Montenegro’s generation mix influences export opportunities and operational outcomes. Additional wind and solar capacity could increase the volume of potentially low-emission electricity available for export. Hydropower output depends on rainfall and reservoir conditions, with drought able to affect domestic dispatch and the balance between exports and imports.
Export earnings can also be affected by transmission constraints, day-ahead price differentials, balancing exposure and interconnector outages. An illustrative export tranche of 50,000 MWh assigned chargeable emissions of 0.4 tCO₂e/MWh would correspond to 20,000 tonnes of CO₂ equivalent. At a certificate price of €82.32 per tonne, gross certificate exposure would be €1.646 million before legally applicable adjustments.
The calculation is not an official emissions factor for Montenegro and does not establish liability for any specific transaction. It illustrates how reliance on a relatively narrow Italian market-price premium could become uneconomic if the importer must apply high default emissions values.
Lender modelling and documentation for CBAM-qualified exports
Lenders evaluating new Montenegrin renewable projects are directed to distinguish ordinary domestic and regional electricity sales from exports represented as CBAM-qualified. Relevant documentation includes the acquiring trader and the EU authorised declarant. It also includes PPA provisions, metering systems, TSO nomination files and settlement adjustments.
The independent verifier’s data requirements are also part of the documentation set described for CBAM-related financing assessments. A project may remain bankable on conventional electricity-market revenues even if additional CBAM benefits are too uncertain to support financing.
Carbon-market changes versus electricity eligibility
An EU agreement reached on Oct. 20 would increase the market stability reserve’s allowance invalidation threshold to 700 million. The change could influence longer-term carbon-price scenarios but does not alter Montenegro’s interconnector capacity. It also does not automatically make exported electricity eligible for actual-emissions treatment under CBAM methodology.
Carbon prices, electricity-market spreads and the technical evidence required for CBAM claims are therefore treated as separate risk factors in modelling described in the source material. The interconnector’s commercial value depends on whether flows run from Montenegro to Italy or in the opposite direction.
Montenegro may export when regional renewable output is strong and Italian prices support deliveries. It may need to import when hydropower reservoirs are depleted or when domestic thermal units are unavailable.
Import-export directionality and allocation scenarios
The CBAM treatment applied to electricity entering the EU affects economics for exports from Montenegro to Italy. It should not be applied automatically in the same way to electricity flowing from Italy into Montenegro. A robust project model should use separate seasonal and hourly import-export scenarios.
The modelling approach described includes accounting for line maintenance and restrictions on allocated capacity when assessing import-export outcomes under CBAM-related assumptions.
Generation ownership versus transmission access
Project developers are required to distinguish their contractual rights from those held by electricity traders and transmission-system operators. Owning a wind farm in Montenegro does not provide unrestricted access to the interconnector.
Physical scheduling, transmission-capacity procurement and customs-related declarations may involve multiple independent entities. Before lenders recognise an assumed CBAM benefit in project valuation, they should review executed agreements and the operational process used to collect and reconcile evidence.
A premium dependent on potential regulatory reform is described as less bankable than one supported by a documented export chain under rules already in force.
Differentiated export product requirements for audit-ready allocation
The opportunity described for Montenegro involves developing a differentiated export product tied to an identified generating installation. The product would require a credible physical and contractual delivery route alongside an audit-ready allocation of every claimed megawatt-hour.
The 600 MW underwater interconnector provides access to Italy, while the quality of the contractual chain and verification process determines whether that access can support sustained low-carbon trading advantages under CBAM-related requirements.
