Renewable energy financing models need to separate revenue from electricity sales from additional income that depends on Carbon Border Adjustment Mechanism (CBAM) eligibility. A project can still meet generation targets and contractual availability requirements while not securing a CBAM-related premium due to issues in nominations, emissions evidence, or verification.
For lenders, the distinction affects revenue forecasts, debt sizing, and debt service coverage ratio (DSCR) calculations. Core financing inputs such as electricity output, market prices, curtailment, offtaker creditworthiness, and operating availability remain relevant, while conditional CBAM-linked payments add an additional revenue risk.
Access to actual emissions values for imported electricity
Under the current framework, imported electricity generally uses the default-values route unless all requirements for installation-specific actual emissions values are met. These requirements include a qualifying physical power purchase agreement (PPA), applicable network conditions, and a generating installation below 550 g CO₂/kWh fossil-fuel-origin emissions.
The framework also requires firm nominations matched with production over periods of no more than one hour. Independent verification must be supported by at least monthly interim evidence.
CBAM timing extends beyond electricity generation. For electricity imported in 2026, sales of CBAM certificates are scheduled to begin on 1 February 2027, with the first annual CBAM declaration and certificate surrender deadline on 30 September 2027.
From 2027, certificate pricing moves to weekly auction-price averaging. Quarterly certificate-holding requirements also become part of treasury planning.
Separating CBAM-linked income from contracted electricity revenue
The potential for CBAM-related revenue can depend on contractual arrangements, the proportion of nominations matched to production, completeness of supporting data, verification findings, and the status of the importer. Because this income depends on eligibility and evidence requirements, it differs from the project’s underlying electricity revenue.
Financing structures therefore need to treat CBAM-linked value as separate from contracted commodity revenue. A conservative base case can recognize contracted electricity revenue while applying a haircut to unproven CBAM-related upside until an operating track record is established.
Consistency between technical assumptions and financing models
Investment committees need consistent assumptions across financial models and technical due-diligence reports. If a model assumes that 85% of electricity volumes qualify for the relevant treatment, operational records must show that the project can achieve a representative eligible share at that level.
A mismatch between the assumed qualification ratio and verifiable operating performance affects valuation. Such discrepancies cannot be treated solely as a compliance matter.
Where the electricity offtaker is a steel or aluminium producer, lenders must also establish the commercial basis for any additional payment. Under current CBAM treatment for metal goods, purchased renewable electricity may not directly reduce the buyer’s CBAM certificate liability.
The premium may instead relate to energy-price hedging, customer requirements, corporate decarbonisation objectives, or preparation for future regulatory developments. Lenders therefore need to distinguish how any additional payment is commercially justified from how it interacts with CBAM obligations.
Monitoring eligibility indicators ahead of DSCR impacts
Lenders should compare financial model assumptions with a monthly operating dashboard rather than relying only on an annual assurance cycle. Indicators such as a declining eligible share, recurring documentation exceptions, or excessive dependence on a single intermediary can signal emerging problems before they appear in DSCR.
Debt sizing should be based on cash flows available under the selected stress scenario. Revenue assumptions that rely on unproven regulatory interpretations, incomplete evidence, or operational performance not yet demonstrated should remain optional upside rather than required funding for debt service.
EU reform proposal COM(2025) 989 under negotiation
The financing model must distinguish between rules currently in force and potential changes under COM(2025) 989. The proposal would alter electricity treatment under CBAM by changing the methodology for electricity default values and parts of the conditions governing actual values.
The proposal would also broaden physical PPAs to include intermediaries and modify congestion and nomination framework elements. The Council adopted its negotiating position on 12 June 2026, followed by the European Parliament position on 15 September 2026.
The proposal remains under interinstitutional negotiation and has not become enacted legislation. Its potential effects should be assessed separately from current-law pricing and should not be incorporated into financing assumptions as if changes were already applicable.
For renewable energy lenders, the central distinction remains between electricity revenue secured under the commercial contract and additional CBAM-linked value dependent on eligibility, measurable performance, and availability of supporting evidence when cash flow is needed to service debt.
