Banks financing renewable projects in the Western Balkans are increasingly focused on whether intended customers can use electricity as assumed in project business plans. The Carbon Border Adjustment Mechanism (CBAM) is extending this due-diligence question into renewable-energy structures. The issue is most relevant when project revenues rely on exports to the EU or premium supply to export-oriented industry.
Due diligence expands beyond generation capability
Traditional renewable-project due diligence covers resource, construction, grid connection, permits, operating costs and contracted revenues. An additional layer examines the commercial usability of electricity attributes tied to the project’s value proposition. Where a project expects a premium linked to the customer’s carbon strategy, lenders need to verify whether the contractual and evidence structure supports that claim.
The evidence and contracting elements highlighted include power purchase agreement (PPA) architecture, metering, generation allocation, certificates and delivery arrangements. This framework connects how electricity attributes are handled with whether those attributes can be used in line with revenue assumptions. The focus shifts from output capability alone to how attributes are evidenced and delivered to counterparties.
Impact on green-premium revenue assumptions
A PPA can appear bankable from a conventional power-market perspective while still weakening if part of the premium depends on a carbon claim that cannot be substantiated. In contrast, strong documentation and allocation systems can increase the value of renewable output for industrial buyers with specific sourcing needs. This affects how lenders evaluate whether expected premiums align with evidence requirements.
Banks may add a carbon and evidence due-diligence workstream alongside legal, technical and financial reviews. Projects with stronger evidence architecture can gain an advantage in this assessment process. Banks also gain improved visibility over assumptions behind green-premium revenue.
Offtaker products and financing structures
Industrial offtakers receive electricity products designed around their sourcing needs, including how renewable and carbon characteristics are intended to be used. Technical, legal and verification advisers take on additional due-diligence tasks connected to evidence handling. The next lending question becomes whether the buyer can use renewable and carbon characteristics as assumed by the revenue model.
Renewable projects across Southeast Europe are being financed using combinations of merchant exposure, contracts for difference (CfDs), guarantees and corporate offtake. In that context, lenders evaluate not only who purchases electricity but also whether contractual arrangements support the intended use of its renewable and carbon attributes.
