Due Diligence

Technical Due Diligence (TDD) is an extensive document review process in which a complete assessment is made of all potential risks to the realisation or successful operation of a wind farm project. The goal of this assessment is to determine the commercial feasibility of the proposed project.  Our due diligence services are tailored to suit individual client needs including developers, investors, private equity institutions or lenders.

We will review and provide an opinion on the following (the list is not exhaustive):

  • Project investment costs.
  • Wind farm design, including review of macro and micro siting, wake effects, and potential upwind development effects.
  • Wind conditions and weather conditions at the Project site (which could impact the construction phase).
  • Wind assessment and energy yield calculation for the project, including uncertainty levels. Estimate of gross and net energy production for P50, P75, P90, P95, and P99 conditions.
  • Technical Evaluation of the Wind Turbines Design and Manufacturer including past performance of the wind turbine under similar weather conditions, serial defects, etc.
  • Conceptual design, adequacy and performance characteristics of the selected turbine for the wind and weather conditions at the project site.
  • Review of performance guarantees (availability, power curve), including guarantees provided by the turbine and other equipment manufacturer.
  • The load analysis prepared by the turbine manufacturer. ¬†Assess and estimate basic lifetime calculations for all major components of the wind turbine. ¬†Independently verify the expected key component load exceedance percentages based on the site specific conditions.
  • Ability of the wind farm to comply with grid code requirements.
  • The conceptual design and the capability of the selected grid connection and other electrical equipment, especially for application to the wind turbine and its characteristics.
  • Technical data inputs and calculations for accuracy, reasonableness and consistency with projection of energy production, project contracts and permits.
  • Environmental Permits, planning consent and other permitting regimes.
