The European Commission’s consolidated guidance states that renewable electricity imported into the EU does not automatically qualify for a zero or near-zero value under the Carbon Border Adjustment Mechanism (CBAM). Importers seeking to apply installation-specific actual emissions must meet several conditions. The requirements are designed to ensure that claims are supported by verifiable documentation.
Conditions for installation-specific actual emissions
To use actual emissions, the electricity supply must be covered by a power purchase agreement (PPA) between the authorised CBAM declarant and the electricity producer in the third country. The generating installation must be directly connected to the EU transmission system. Alternatively, the parties must show that no physical congestion existed between the installation and the Union network at the time of export.
The generating installation must also have fossil-fuel emissions of no more than 550 gCO₂/kWh. The guidance indicates that meeting one element is not sufficient on its own. Eligibility depends on satisfying the cumulative contractual, physical, and emissions thresholds.
Hourly nomination and matching requirements
For cross-border electricity trading, the guidance requires that the quantity claimed is firmly nominated against allocated interconnection capacity by the responsible transmission system operators. The nominated capacity and electricity production must relate to the same period. That period cannot exceed one hour.
The Commission guidance also states that renewable energy certificates or a green electricity supply contract alone do not establish eligibility for actual-emissions treatment. Instead, an importer’s claim must be backed by a contractual chain linking a named generating installation to the authorised CBAM declarant. The chain must be supported by acceptable physical and scheduling evidence.
Evidence requirements for Serbia and Montenegro exporters
For electricity exporters in Serbia and Montenegro, ordinary power-market records are described as important evidence for CBAM reporting. Where importers seek to use actual emissions rather than the applicable default emissions factor, they need to reconcile multiple data sources. These include supervisory control and data acquisition (SCADA) systems, commercial metering, nomination files, allocated interconnector capacity, congestion evidence, and PPA terms.
The reconciliation is required at an hourly level to support cross-border reporting. The ability to demonstrate this chain can determine whether the emissions characteristics of imported renewable electricity are reflected in the CBAM calculation. The guidance links eligibility to whether documentation can withstand verification.
Certificate price levels increase compliance stakes
The financial implications are highlighted as CBAM certificate prices rise. The European Commission set the reference price for the third quarter of 2026 at EUR 82.32 per tonne of CO₂ equivalent. Electricity is not subject to a free-allocation adjustment because EU power generation generally does not receive free allowances under the EU Emissions Trading System.
This means the carbon-price signal for imported electricity is described as comparatively direct. As a result, documentation supporting actual-emissions claims becomes more consequential for importers facing certificate costs tied to CBAM calculations.
PPA documentation as a commercial compliance factor
For electricity producers and their EU customers, the guidance frames eligibility as dependent on whether associated evidence meets CBAM requirements. If cross-border matching cannot be demonstrated, an importer may still face an obligation calculated using the applicable default emissions factor. Low-emission generation alone does not guarantee a favourable outcome under CBAM.
For lenders and power buyers, whether a PPA can support CBAM-compliant reporting may become a commercially relevant attribute alongside electricity price, contracted volume, and credit support. The guidance emphasizes that contractual, physical, and scheduling evidence must be capable of verification to support actual-emissions treatment.
