Valuation of wind farms – well-founded valuation of complex energy infrastructure

Today, wind farms are among the most important infrastructure assets in the field of renewable energies. At the same time, their assessment is much more complex than that of individual wind turbines. Investors, operators and project developers therefore need a well-founded, market-oriented valuation in order to be able to derive realistic market prices for complete wind farm portfolios.

The value of a wind farm does not result solely from the sum of the individual turbines. Economic, technical and regulatory framework conditions that influence the overall project are also decisive.

Why the valuation of wind farms requires special expertise

A wind farm is a long-term infrastructure project with stable cash flows, but also complex structures. In addition to the technical properties of the wind turbines, economic conditions in particular play a central role.

For a realistic valuation, the following factors are taken into account, among others:

• Number, type and power of installed wind turbines
• Years of manufacture and remaining technical service life
• Historical electricity production and yield forecasts
• Remaining terms of EEG remuneration or power purchase agreements (PPA)
• Location quality and wind potential
• Grid connection capacity and feed-in situation
• Structure of lease agreements and land rights
• Financing structure and existing loan agreements
• Service and maintenance contracts
• Dismantling obligations and provisions

These factors influence both the long-term revenues and the risk assessment of a wind farm from an investor's point of view.

Wind farms as an infrastructure investment

Institutional investors view wind farms primarily as infrastructure investments with stable cash flows. Therefore, the economic performance of the overall project plays a decisive role.

Typically, the rating is based on a combination of:

• Cash flow models over the remaining project life
• Comparison with current market transactions
• Technical and regulatory risk assessment
• Assessment of the long-term development of the electricity market

The more stable the revenue structure, the more attractive the wind farm is for long-term investors such as infrastructure funds, energy suppliers or pension funds.

Data-driven valuation based on real market transactions

A reliable valuation can only be made if it is based on real market movements. In addition to business valuation models, transaction data from actual buying and selling processes is therefore crucial.

The valuation is based on, among other things:

• more than 10 years of market movement data
• a documented transaction volume of over 11 billion euros
• real international buying and selling processes via the trading platform wind-turbine.com

This data enables an evaluation that is based on actual market prices – not purely theoretical model calculations.

Practical. In line with the market. Investor-oriented.

Different perspectives of buyers

The value of a wind farm depends heavily on who values it. Different groups of buyers pursue different strategies:

• Strategic operators focus on long-term energy production
• Infrastructure funds assess stable cash flows and return profiles
• Energy suppliers look at synergies in the existing portfolio
• Repowering investors analyse future expansion potential

A professional valuation takes these different perspectives into account and derives realistic market prices from them.

Repowering as an additional value factor

For many older wind farms, the future repowering potential plays a decisive role in the market value. Sites with good approval prospects for higher-performance plants can achieve significantly higher valuations.

The decisive factors here are:

• Space availability
• Distance regulations
• Grid connection capacities
• regional licensing conditions

Investors therefore often calculate not only the current operation, but also the long-term expansion options of a location.

For whom is a wind farm valuation useful?

• Operators who are considering a sale of their wind farm
• Project developers in the context of exit strategies
• Investors for the valuation of existing portfolios
• Operations manager with sales mandate
• Owners facing repowering decisions
• Financing institutions for asset valuation

A realistic valuation creates transparency, strengthens the negotiating position and reduces the risk of mispricing in transactions.

Free market value assessment for wind farms

Operators and owners can have the current market value of their wind farm analysed free of charge. The valuation is carried out:

• data-based
• transaction-oriented
• taking into account current market movements
• based on technical, economic and regulatory factors

The goal is a realistic assessment of what a wind farm can actually achieve on the market.

Market knowledge as a decisive success factor

The valuation of wind farms requires in-depth market knowledge, access to real transaction data and experience with international investor structures.

Knowing the market value of your wind farm creates a solid basis for sales decisions, investor negotiations and strategic portfolio optimisations.
