Potential changes to the Carbon Border Adjustment Mechanism (CBAM) could affect the economics of electricity exports from the Western Balkans to the European Union, making emissions evidence and regulatory timing important alongside wholesale power prices.
The reform package proposes changes to the calculation of embedded emissions in imported electricity, together with an expansion of CBAM to downstream products and stronger measures against circumvention.
The European Parliament adopted its negotiating position on 15 September. The final provisions remain subject to negotiations with EU member states, meaning utilities and traders must distinguish between proposed changes and the rules currently applicable to electricity imports.
Serbia and Montenegro face carbon-cost considerations
For electricity transactions involving Serbia and Montenegro, export economics depend on the relationship between a power transaction’s carbon exposure and its wholesale margin.
A positive spread between exchange prices does not by itself establish that an electricity export will remain profitable after all applicable costs are taken into account.
Renewable electricity producers also face requirements concerning evidence for low-emissions claims. Statements that electricity is green cannot automatically be treated as determining its CBAM treatment without considering the applicable evidentiary requirements.
Regulatory assumptions affect export investment models
For lenders assessing projects, revenue forecasts that depend on a proposed CBAM methodology remain conditional until the legislative process is completed.
Financial models therefore need to identify the regulatory assumptions underlying projected export margins and show how those margins could change if negotiations take longer or result in different provisions.
The investment relevance of the reform is linked to its potential impact on EU market access and electricity export margins. With the final rules unresolved, contracts and financial models need to make the associated regulatory assumptions visible.
