Expert opinion for wind turbines – What operators need to know

Expert opinions play a central role in the wind energy sector – whether in the continued operation, the sale of wind farms or the valuation of existing turbines. Without an independent technical and economic assessment, it is difficult to seriously assess the risks, condition and value of a wind turbine. It is therefore crucial for operators to know what types of appraisals are available and what to look out for when commissioning them.

Why are expert reports important?

An expert report provides an objective basis for assessing the technical condition, safety and economic efficiency of a wind turbine. Whether for continued operation after 20 years, for sale or to prepare for repowering – a neutral assessment creates transparency and trust. Many insurers, banks and potential buyers require an up-to-date appraisal as a prerequisite for concluding contracts or financing.

Types of expert opinions on wind turbines

Depending on the goal and occasion, expert reports differ in scope and focus.
Among the most important are:

• Technical condition and continued operation reports: Checking whether a plant can continue to operate safely after the end of its design life. Load assumptions, material fatigue and the condition of the tower, foundation and rotor blades are analysed.
• Wind and site surveys: Evaluates the wind conditions and yield prospects of a site. Such appraisals are particularly relevant for planning, revaluation or sale.
• Due diligence report: Used in the purchase or sale of a wind farm to identify and assess technical, legal and economic risks.
• Safety and stability assessments: Check whether the foundation, tower and supporting structures meet the requirements and whether there are no safety-relevant defects.
• Environmental and species protection assessments: Part of approval and continued operation procedures, especially in the case of modifications or repowering.

What operators should pay attention to

In order for an expert opinion to be reliable, operators should pay attention to the following points:

• Independence of the expert – no economic interests in the result.
• Qualification and experience in the wind energy sector.
• Complete data basis (service reports, measurement data, inspections).
• Clear documentation and transparent methodology.
• Realistic assessment of the remaining useful life and concrete recommendations for action.
• Integration of economic factors (costs, earnings, risks) – especially important in the case of continued operation or sale.

Consulting and service providers in the industry

Since expert opinions require specialist technical knowledge, the support of experienced consulting firms is recommended. These help to select the right type of appraisal, interpret results and derive the appropriate strategy – whether continued operation, optimisation or sale. On wind-turbine.com, operators will find a broad network of qualified providers who offer both expert opinions and comprehensive consulting services in all aspects of technical assessment, insurance, approval and asset marketing.

Result

For operators of wind turbines, a well-founded appraisal is more than a formality – it is the basis for safety, profitability and value retention. Whether for continued operation, sale or financing: Only with an independent assessment can well-founded decisions be made and risks minimized. Those who involve advice and expertise at an early stage create planning security and strengthen the market value of their investment.
