The European Commission’s transitional registry recorded approximately 3 million MWh of electricity declarations attributed to Montenegro between the fourth quarter of 2023 and the second quarter of 2025. The figure formed part of an approximately 96 million MWh total reported across all electricity-import origins during the same period. The registry entries represent historical CBAM declarations rather than Montenegro’s verified net electricity exports in 2026 or volumes delivered through a specific interconnector.
Montenegro’s electricity interconnection with Italy provides a commercial route into the EU power market. At the same time, the EU Carbon Border Adjustment Mechanism (CBAM) increases the importance of documentation supporting claims about emissions linked to exported electricity. Generators, traders and investors are expected to assess whether evidence provided with a supply arrangement meets the requirements for the carbon treatment claimed.
Montenegro–Italy interconnector capacity and market access
The Montenegro–Italy subsea high-voltage direct-current interconnector was developed by Terna and connected to the regional network at Lastva. Its initial transfer design capacity is 600 MW. The infrastructure is intended to provide access to the Italian wholesale electricity market and wider regional trading routes.
The amount that can be transferred depends on available capacity, auctions, nominations and prevailing electricity-system conditions. Any plans for additional capacity need to be distinguished from infrastructure already commissioned. For CBAM purposes, access to the Italian market is only one element of the commercial arrangement.
Requirements for declaring actual emissions under CBAM
An authorised EU declarant must establish the appropriate emissions calculation for imported electricity. The declarant must also show that conditions for using actual emissions values have been met. These conditions include a required contractual relationship between the producer and declarant.
The conditions also cover relevant physical connection or hourly non-congestion evidence, alongside other prescribed legal tests. A guarantee of origin matching the electricity supply does not, on its own, establish eligibility to declare zero emissions under CBAM. The documentation therefore needs to align with both contractual and physical linkage requirements.
Carbon price reference and implications for contract economics
The financial implications of emissions accounting are described as increasing in importance. The CBAM certificate reference price reached €82.32 per tonne of CO₂ equivalent in the third quarter of 2026.
An exporter whose supply qualifies for actual-emissions treatment and is supported by reliable evidence may be able to offer a more competitive net cost than a supplier whose importer must use the applicable default value. The extent of any advantage depends on emissions values and deductions permitted under CBAM rules for the specific import arrangement.
Calculations based on multiplying a national carbon saving by an assumed emissions difference are described as misleading. Commercial comparisons are expected to use the applicable methodology and substantiated data for the electricity actually imported.
Hydropower and renewable supplies tied to eligibility evidence
Elektroprivreda Crne Gore (EPCG) hydropower generation and Montenegro’s developing renewable portfolio are cited as potential sources for contractually structured electricity supplies. Such supplies would depend on demonstrating relevant eligibility conditions under CBAM.
Preparing these arrangements may require improved metering systems, scheduling records, controlled allocation of generation, independent assurance preparation and coordination with grid operators. Renewable generation alone does not remove the need to establish required physical and contractual links between production and import.
Aluminium trade exposure differs from electricity CBAM treatment
Montenegro’s aluminium industry involves separate considerations under CBAM-related reporting questions. Primary electrolysis at KAP stopped in 2023, while subsequent billet and alloy processing has relied on imported metal.
For these aluminium products, issues such as metal origin, precursor traceability and direct emissions differ from requirements governing electricity imports. Electricity consumed within Montenegro is not, by itself, an imported EU electricity good subject to CBAM as such.
This distinction is relevant for industrial investors assessing combined exposure across electricity and aluminium-related trade. Which CBAM requirements apply depends on product classification and supply-chain structure.
Investor due diligence on cross-border export eligibility
For lenders and investors, a credible cross-border electricity export programme should connect key elements before assigning a carbon-related advantage to projected cash flows. These elements include the generating installation, offtake agreement, dispatch schedules, interconnector arrangements and EU importer responsibilities.
The European Commission’s proposed changes to electricity emissions accounting could affect incentives in future transactions. As of 12 October 2026, those changes remained under negotiation and were not described as existing flexibility for current assessments.
Montenegro’s interconnector provides physical access to an important EU electricity market. Under CBAM, supporting evidence becomes a separate commercial consideration in determining whether emissions attributes claimed for exported power can be recognised under applicable rules.
The evidence requirement could become decisive when generators, traders and buyers negotiate future cross-border electricity contracts involving Italy.
