Aligning Wind, Solar and Numbers: IFRS in Renewable Energy

A renewable energy group owning and operating wind farms and solar parks across several countries had built its portfolio through a series of project‑financed special purpose vehicles. Each SPV maintained its own local GAAP accounts to satisfy lenders and regulators. At the holding level, management relied on aggregated spreadsheets that lacked consistency and detail. As the group prepared for a strategic partnership with an infrastructure fund, investors requested audited IFRS consolidated financial statements and robust forecasts. Radner’s team was engaged to implement international accounting management under IFRS, with a strong emphasis on project finance structures and long‑term contracts.

Unlike traditional corporate groups, this renewable energy portfolio was organized around ring‑fenced SPVs with non‑recourse debt. Power purchase agreements, land leases, and maintenance contracts varied by project and jurisdiction. Radner’s team began by mapping the legal and financial structure of the group, identifying all entities, ownership percentages, and financing arrangements. This mapping exercise revealed joint ventures, minority interests, and complex shareholder loans that had not been fully reflected in previous internal reports. The first objective was to determine the appropriate consolidation method for each entity under IFRS 10, IFRS 11, and related standards.

Control assessment became a central task. Some SPVs were wholly owned, while others involved co‑investors or development partners with specific rights. Radner’s team analyzed shareholder agreements, voting rights, and reserved matters to determine whether the group had control, joint control, or significant influence. In several cases, contractual arrangements gave the group power over relevant activities despite minority shareholdings. These entities required full consolidation, changing the perceived leverage and asset base of the group. The findings were documented in a clear control matrix, which became a cornerstone of the new IFRS consolidation framework.

Once the consolidation perimeter was defined, Radner’s team turned to the accounting treatment of project finance debt and related covenants. Each SPV had its own loan agreements with banks, often including sculpted repayment schedules, cash sweep mechanisms, and reserve accounts. Under local GAAP, these features were sometimes treated inconsistently. IFRS required a more precise classification of financial liabilities, amortized cost calculations, and effective interest rate determination. Radner’s team built detailed debt models for each SPV, capturing all relevant cash flows and covenant tests. These models fed into the consolidated financial statements and into management’s risk monitoring.

Revenue recognition and asset accounting were relatively straightforward in principle but complex in practice. Power purchase agreements specified tariffs, indexation mechanisms, and sometimes floor and cap structures. Radner’s team reviewed these contracts to ensure that revenue was recognized based on actual energy delivered and contractual prices, with appropriate accruals for balancing and grid fees. Property, plant, and equipment accounting required careful componentization of wind turbines and solar installations, as different components had different useful lives. The team worked with engineers to define components and estimate useful lives, aligning accounting depreciation with technical reality.

Decommissioning and environmental obligations were another critical area. Many project contracts and permits required the SPVs to dismantle installations and restore land at the end of the asset life. Under local GAAP, these obligations had often been disclosed but not fully recognized as provisions. IFRS demanded recognition of decommissioning provisions at present value, with corresponding adjustments to asset cost. Radner’s team collaborated with technical advisors to estimate future dismantling costs and with treasury to determine appropriate discount rates. The resulting provisions increased the balance sheet but also provided a more honest view of long‑term obligations.

To create a sustainable international accounting management model, Radner’s team designed a standardized reporting package for all SPVs. The package included templates for trial balances, fixed asset movements, debt schedules, covenant compliance, and key operational metrics such as availability and production. Local finance teams and external service providers were trained to complete these templates according to IFRS‑aligned instructions. A central consolidation system was configured to import the data, perform currency translation, and generate consolidated statements and notes. This replaced the previous patchwork of spreadsheets and manual adjustments.

Monthly and quarterly closing processes were restructured to align with lender reporting and investor expectations. Many SPVs already had strict reporting deadlines to satisfy banks, but formats and definitions differed. Radner’s team harmonized these requirements with the group’s IFRS timetable, minimizing duplication of effort. A closing calendar defined when SPVs had to submit data, when intercompany balances were reconciled, and when consolidation adjustments were posted. Automated checks in the consolidation system flagged inconsistencies in debt balances, interest expense, and reserve accounts. Over time, the closing process became more predictable and less dependent on individual spreadsheet skills.

Communication with stakeholders was integrated into the project from the outset. The infrastructure fund interested in partnering with the group wanted to understand not only historical performance but also future cash flows and risk allocation. Radner’s team prepared reconciliations between local GAAP and IFRS results, highlighting the impact of consolidation decisions, decommissioning provisions, and financial instrument classifications. Scenario analyses showed how changes in energy prices, production volumes, or interest rates would affect IFRS earnings and covenants. This level of transparency strengthened the group’s negotiating position and built trust with potential partners.

Risk management practices evolved alongside the accounting transformation. The structured view of project finance debt and covenants allowed the group to identify SPVs with limited headroom or concentration of refinancing risk. Radner’s team helped integrate these insights into a group‑wide risk dashboard, linking financial indicators to operational metrics such as turbine availability and curtailment. Provisions for legal disputes, grid connection issues, and warranty claims were reviewed and standardized under IFRS. The board gained a clearer picture of downside scenarios and could prioritize mitigation actions accordingly.

Training and knowledge transfer were essential to ensure that the new model would endure beyond the initial implementation. Radner’s team conducted workshops for group finance, SPV accountants, and project managers. Topics included IFRS consolidation principles, decommissioning provisions, hedge accounting, and disclosure requirements specific to the renewable energy sector. Real project examples were used to illustrate concepts, such as how a refinancing or a change in ownership structure would affect consolidation and financial statements. Documentation of policies and procedures was compiled into a comprehensive group accounting manual.

Hedge accounting under IFRS 9 became a focus area as the group sought to manage exposure to interest rate and energy price risks. Some SPVs had entered into interest rate swaps or price hedges, but documentation for hedge relationships was incomplete. Radner’s team worked with treasury to formalize hedge designations, effectiveness testing, and documentation. Where hedge accounting was feasible, volatility in profit or loss was reduced by recognizing fair value changes in other comprehensive income. This treatment aligned better with how management viewed risk management activities and improved the stability of reported earnings.

As the international accounting management framework matured, the group began to use IFRS‑based data for strategic decisions. Comparative analysis of projects across countries and technologies revealed differences in performance and risk‑return profiles. The group identified opportunities to refinance certain SPVs at better terms and to divest non‑core assets. The improved visibility into decommissioning obligations and maintenance costs informed decisions about life extension projects and repowering of older wind farms. Financial and operational planning became more integrated, supported by consistent, high‑quality data.

When negotiations with the infrastructure fund reached an advanced stage, the group was able to provide detailed, audited IFRS consolidated financial statements and forward‑looking models. Radner’s team supported management during due diligence, answering technical questions about consolidation, provisions, and financial instruments. The robustness of the international accounting management framework reduced perceived risk for the investor and facilitated agreement on valuation and deal structure. The resulting partnership brought fresh capital for new projects and validated the group’s governance and reporting capabilities.

For this renewable energy group, adopting IFRS and establishing disciplined international accounting management delivered benefits far beyond compliance. The consolidation of SPVs, transparent treatment of project finance debt, and recognition of long‑term obligations created a more accurate and actionable picture of the business. With Radner’s team guiding the process, the group gained the financial clarity needed to scale its portfolio, manage risks, and attract long‑term institutional capital, all while maintaining the trust of lenders, regulators, and local stakeholders.
