Looking to acquire, insure, or optimize the performance of a wind farm?
Our teams carry out targeted audits and full-scale due diligence. We also support ongoing operations with advanced solutions and real-time applications designed to optimize wind turbine performance.
Each year, our experts audit and support several hundred megawatts of projects and operational assets.
Thanks to our in-depth knowledge of market dynamics and the profitability challenges of renewable assets, we provide comprehensive solutions that address operational requirements in the field as well as managerial and financial needs at corporate level.

Technical Due Diligence
Objectives
Technical due diligence complements regulatory due diligence. It validates the technical characteristics of the wind farm and assesses the uncertainties and risks associated with production forecasts.
More specifically, it seeks to:
Detect inconsistencies between design assumptions, production forecasts, and O&M conditions
Confirm the main technical features of the farm or portfolio: wind resource, losses, performance, availability, production
Quantify uncertainties and risks that could affect these technical features
Define realistic assumptions to be used in the financial valuation model
Recommend and prioritize appropriate investment conditions in the context of a purchase offer
Content / Methodology
To determine the production to be retained and quantify risks of variation in its value, we carry out:
Collection of key documentation: equipment supply contracts, O&M agreements, insurance, grid connection and access contracts, resource and production studies, etc.
Technical review and assessment of equipment design and sizing
Critical analysis of wind resource and energy yield studies
Review of contractual technical clauses: performance, availability, and production guarantees
Assessment of Grid Connection Conditions
Objectives
This study complements technical due diligence. It ensures that the internal electrical installation and its connection to the transmission or distribution grid are technically and economically optimized.
It specifically aims to:
Identify inconsistencies between internal installation design and grid connection infrastructure
Validate the technical characteristics of the connection
Quantify uncertainties and risks impacting production
Provide realistic assumptions for the financial valuation model
Recommend conditions precedent or potential technical improvements
Special Case: Projects Under Development
For projects under development, the analysis can be supplemented with a forward-looking review of draft connection agreements, operating contracts, and grid access terms under current regulation.

Audit of Equipment Condition
Objectives
This audit verifies that mechanical, electrical, and hydraulic components are in proper working and maintenance condition, and identifies corrective measures where necessary.
It specifically aims to:
Provide an inventory of installed equipment
Assess the actual condition and maintenance of key equipment
Estimate expected lifespan of assets for the financial model
Identify corrective actions before or after the transaction
Recommend investment conditions: replacement needs, spare parts to be stocked, etc.
Content / Methodology
The scope of the technical audit depends on prior findings from due diligence, performance reviews, and warranty analysis.
It may include targeted inspections and specific tests on selected turbines (infrared scans, gearbox endoscopy, vibration analysis, insulation testing, etc.).
Typically, visual inspections cover blades, HV/LV cabinets, generators, power electronics, and gearboxes.
Performance and Failure Risk Analysis
Objectives
This analysis complements technical due diligence by identifying causes of underperformance and quantifying the impact of maintenance operations on asset availability.
It specifically aims to:
Estimate guaranteed and non-guaranteed downtime of each turbine and of the farm as a whole
Identify root causes of unavailability
Recommend technical assumptions for use in financial valuation models
Identify turbines requiring further on-site audits and tests
Assess the adequacy of warranty coverage and guaranteed availability levels
Content / Methodology
The study involves:
Review of key documentation: production, O&M reports, maintenance contracts, failure codes, etc.
Estimation of resource characteristics and calculation of unavailability rates by cause
Analysis of preventive and corrective maintenance frequencies and durations per turbine
Assessment of corrective maintenance relevance and consistency of preventive maintenance with site conditions
Simulation of the actual power curve, yield, and operating hours
Benchmarking of actual farm characteristics against manufacturer data and initial yield studies
Applications to Monitor and Optimize Wind Performance
Real-time dashboards provide:
Availability rates of each turbine and the overall farm
Key equipment parameters (oil, temperature, vibration, noise)
Origin, frequency, and impact of shutdowns
Comparison between theoretical and actual turbine output
