CBAM compliance is becoming a project-finance issue for renewable electricity developments in the Western Balkans. The ability to access EU price benchmarks can materially affect revenue, debt-service coverage and equity returns, making the underlying evidence system relevant to lenders.
The Energy Community Secretariat’s estimate that a 130 MW wind project could lose €8.9 million over six monthswhen confined to a domestic market provides a clear indication of the scale. A revenue difference of that size cannot be treated as a minor regulatory contingency. It belongs in the base-case and downside financial model.
Traditional technical due diligence focuses on resource assessment, energy yield, grid connection, EPC risk, operating costs and plant availability. CBAM adds another layer: whether the electricity can be demonstrated as originating from the financed renewable installation when imported into the EU.
Lenders will need to review the complete metering chain from turbine, inverter or hydro unit to the commercial settlement point. SCADA records, revenue meters, loss calculations, cross-border nominations and market settlements must reconcile on an hourly basis.
The PPA also requires detailed examination. Fixed-volume and shaped contracts may introduce replacement electricity from intraday or balancing markets. That energy may be subject to national default factors, creating an unmodelled cost and weakening the contracted margin.
Due diligence should determine who bears this risk, how it is calculated, whether it is capped and whether the offtaker can pass the cost back to the generator. Termination and price-reopening clauses may be triggered by changes in CBAM rules, verifier availability or the loss of actual-value eligibility.
The verifier interface is another critical area. An accredited verifier must receive at least monthly interim reports, yet verifiers were not expected to become widely available until late 2026 or early 2027. Projects must therefore establish a pre-verification process before the formal verifier is appointed.
A lender-grade evidence pack should include data-governance procedures, controlled monthly reports, meter-calibration records, change logs, contractual allocation records and documented treatment of curtailment, storage and balancing purchases.
The financial model should include at least two revenue cases. The compliant case can assume access to the relevant EU benchmark after capacity and compliance costs. The downside case should use the domestic market price and national default-factor exposure. Delays in verifier accreditation or regulatory approval should be modelled as a time-dependent revenue haircut.
CBAM eligibility is becoming comparable to a permit, grid connection right or long-term offtake condition. The plant can be physically complete and generating, but the expected revenue may remain unavailable because the evidence chain is incomplete.
