Montenegro’s electricity interconnection with Italy provides a commercial route into the EU power market, but the EU Carbon Border Adjustment Mechanism (CBAM) is increasing the importance of documentation supporting claims about the emissions of exported electricity. Generators, traders and investors must consider whether the evidence accompanying a supply arrangement satisfies the requirements for the carbon treatment claimed.
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. This formed part of the approximately 96 million MWh reported across all electricity-import origins during the period. The figures represent historical CBAM declarations, not Montenegro’s verified net electricity exports in 2026 or volumes delivered through a specific interconnector.
Subsea interconnection provides access to the Italian market
The Montenegro–Italy subsea high-voltage direct-current interconnector, developed by Terna and connected to the regional network at Lastva, has an initial transfer design capacity of 600 MW. The infrastructure provides access to the Italian wholesale electricity market and wider regional trading routes.
However, the volume that can actually be transferred depends on available capacity, auctions, nominations and prevailing electricity-system conditions. Plans for additional capacity must also be distinguished from infrastructure that has already been commissioned.
For CBAM purposes, access to the Italian market is only one part of the commercial equation. The authorised EU declarant must establish the appropriate emissions calculation for the imported electricity and demonstrate that the conditions for using actual emissions values have been met.
These conditions include the required contractual relationship between the producer and declarant, relevant physical connection or hourly non-congestion evidence, and other prescribed legal tests. A guarantee of origin that matches the electricity supply does not, by itself, establish eligibility to declare zero emissions under CBAM.
Carbon pricing increases the value of reliable evidence
The financial implications of emissions accounting are becoming more significant. 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 advantage, however, depends on the emissions values and deductions permitted under the rules for the specific import arrangement.
It would therefore be misleading to calculate a national carbon saving by multiplying the headline certificate price by an assumed emissions difference. Commercial comparisons must use the applicable methodology and substantiated data for the electricity actually imported.
Elektroprivreda Crne Gore (EPCG) hydropower generation and Montenegro’s developing renewable portfolio could provide sources for contractually structured electricity supplies, provided the relevant eligibility conditions can be demonstrated. Preparing such 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 the required physical and contractual links between production and import.
Aluminium exposure follows a different route
Montenegro’s aluminium industry presents a separate set of considerations. Primary electrolysis at KAP stopped in 2023, while subsequent billet and alloy processing has depended on imported metal.
For these products, questions surrounding metal origin, precursor traceability and direct emissions differ from the requirements governing electricity imports. Electricity consumed within Montenegro is not, in itself, an imported EU electricity good subject to CBAM as such.
This distinction matters for industrial investors assessing the country’s combined exposure to electricity and aluminium-related trade. The relevant product classification and supply-chain structure determine which CBAM requirements apply.
Financing decisions depend on demonstrable export eligibility
For lenders and investors, a credible cross-border electricity export programme should link the generating installation, offtake agreement, dispatch schedules, interconnector arrangements and EU importer responsibilities before assigning a carbon-related advantage to projected cash flows.
The European Commission’s proposed changes to electricity emissions accounting could alter incentives in the future, but those changes remain under negotiation as of 12 October 2026. They should not be treated as existing flexibility when assessing current transactions.
Montenegro’s interconnector provides physical access to an important EU electricity market. CBAM increasingly makes the supporting evidence a separate commercial consideration, determining whether the emissions attributes claimed for exported power can be recognised under the applicable rules. That distinction could become decisive when generators, traders and buyers negotiate future cross-border electricity contracts.
