Targeted support to facilitate acquisitions

Due diligence validates the technical and regulatory assumptions underpinning a company’s or project’s financial model: What is the actual and forecast production capacity of the wind farm? What is its availability rate? Is the grid connection optimal? Is an extension or repowering project appropriate for the site and resource?

Our consultants’ technical expertise enables them to critically review business plans, manage the audits required to verify installations, and assess the quality of operations and maintenance.

This expertise is central to risk assessment, safeguarding acquisitions through recommendations on conditions precedent, and providing robust inputs for the economic models that underpin investment decisions.

Technical due diligence

Objectives

Technical due diligence complements regulatory reviews by confirming technical characteristics and quantifying uncertainties and risks related to expected production.

Specifically, it aims to:

Identify inconsistencies between design and operating/maintenance conditions

Confirm the key technical characteristics of the wind farm: resource, losses, efficiency, availability, production

Assess uncertainties and risks that could affect performance

Provide realistic assumptions for the financial model

Recommend and prioritize conditions precedent to accompany the purchase offer

Scope of Work

To estimate expected production and assess risks of variation, we:

Collect and analyze key documents: supply contracts, O&M agreements, insurance, grid access agreements, resource and production studies

Assess technology, resource, and equipment sizing

Review resource and production studies

Analyze contract technical clauses: efficiency, availability, production guarantees

Provide recommendations and oversee additional site audits or tests as needed
