Technical Due Diligence
for Wind Assets
Technical Advisory for Wind Asset Transactions and Financing
Our Technical Due Diligence service is designed to provide technical clarity, reduce uncertainty, and offer structured support in wind asset acquisition, divestment, and financing processes. We combine in-depth technical analysis, aeroelastic modeling, structural risk assessment, and contractual-financial review to deliver an independent and actionable view of the asset’s actual condition and value-generation potential.
We tailor the scope and approach according to the stakeholder profile (buyer, seller, or financier), ensuring that technical information is translated into well-founded strategic decisions.
For Buyers
Reduced Uncertainty and Validation of the Investment Case
For strategic investors, infrastructure funds, and IPP platforms, our service provides an independent assessment aimed at protecting equity and validating the investment thesis:
- Identification and quantification of critical technical risks and their economic impact.
- Independent validation of energy production (P50 / P90) and structural margins.
- Assessment of type-site suitability and life extension potential.
- Review of risk allocation in key contracts (O&M, TSA, EPC, PPA).
- Identification of technical contingencies and post-closing optimization opportunities.
Our goal is to turn the asset’s technical complexity into clear risk–return metrics, enabling more robust negotiations and the structuring of well-founded price adjustments or reserves.
For Financiers
Risk Mitigation and Capital Protection
For financial institutions, debt funds, and multilateral organizations, our service provides an independent assessment focused on the bankability of the asset:
- Validation of critical technical assumptions in the financial model (production, availability, degradation, corrective CAPEX).
- Structural risk analysis and life extension scenario assessment.
- Review of technical warranties, covenants, and contractual compliance.
- Evaluation of alignment between technical risk profile and financing structure.
- Early identification of deviations with potential impact on cash generation and financing covenants.
Our goal is to provide a solid technical foundation that supports financing, refinancing, or restructuring decisions, minimizing uncertainty and protecting investment value.
For Sellers
Value Maximization and Strategic Transaction Preparation
For owners, utilities, or platforms preparing a divestment, our approach focuses on anticipating risks and strengthening the asset’s positioning in the competitive process:
- Technical Vendor Due Diligence to identify and mitigate risks prior to market exit.
- Optimization of technical narrative and structured documentation for the data room.
- Assessment of life extension potential or operational improvements to enhance the equity story.
- Identification of technical quick wins with direct impact on valuation.
- echnical support during Q&A in the buyer due diligence process.
Our goal is to reduce discounts due to technical uncertainty, enhance the perceived quality of the asset, and maximize transaction value.
Technical Due Diligence
At Nabla Wind Hub, we provide a comprehensive Technical Due Diligence (TDD) service and life extension advisory, specializing in onshore and offshore wind projects, as well as hybrid assets integrating storage or complementary technologies. Our approach is based on a structured and in-depth technical review of the asset, covering all phases of its lifecycle: from resource assessment and design, to operation and post-commercial performance.
Our multidisciplinary team is supported by experience gained from analyzing more than 800 wind farms worldwide and over a decade of experience in the sector. This expertise allows us to identify critical technical risks, quantify their impact, and provide actionable recommendations that support investment, refinancing, acquisition, or life extension strategy decisions.
Services included in our
Technical Due Diligence
for wind assets
Independent wind resource assessment (EYA)
Critical review of the wind resource assessment and the methodology used to estimate energy production (P50 / P75 / P90), including measurement campaigns, MCP correlations, technical and operational losses, associated uncertainties, and long-term assumptions. The objective is to validate the robustness of the energy estimates and their suitability for financing or acquisition processes.
Comprehensive review of key contracts (TSA, O&M, EPC, BOP, PPA, LLA…)
Technical and contractual analysis of the project’s key agreements to identify risk allocation, availability and performance guarantees, penalty mechanisms, life extension responsibilities, and residual exposure. We assess the consistency between the contractual framework and the technical reality of the asset.
Review of wind turbine and equipment design
Assessment of the wind turbine’s technical design and its main components (blades, tower, foundation, electrical and control systems), including type–site suitability, structural margins, regulatory compliance, and potential deviations from the original design or the actual site conditions.
Lifetime analysis and reliability modeling
Development or review of life extension analyses based on real load data and aeroelastic models, together with techno-financial reliability models that integrate failure rates, future CAPEX/OPEX, and maintenance strategies. This analysis enables the quantification of structural risks and cost scenarios over the medium and long term.
Review of the financial model
Technical validation of the financial model’s critical inputs (energy production, availability, degradation curves, corrective CAPEX, strategic spare parts, and O&M strategy), ensuring consistency between technical assumptions and economic projections.
Verification of financial obligations and contractual commitments
Analysis of covenant compliance, technical warranties, availability commitments, and regulatory obligations, identifying potential deviations and their impact on refinancing, acquisition, or life extension of the asset.
modelo geométrico 3D
The combination of in-depth technical analysis, structural modeling, and experience gained from hundreds of wind farms enables an accurate assessment of the condition and potential of wind assets. This approach provides a solid technical foundation to support strategic decisions related to investment, refinancing, acquisition, or life extension.
