Installation of Small and Medium Wind Turbines in Latvia — Permits, Requirements and Available Support

Installing a wind turbine in Latvia is simpler than most people think.

The installation of small and medium wind turbines in Latvia often seems complicated — many people have questions about permits, approvals and costs.

• Is a construction project required?

• Can a turbine be installed on private property?

• What financial support is available?

In this article, we will look at how wind turbine installation works in practice in Latvia, what the main requirements are, and what financing opportunities are available.

Is it allowed to install a wind turbine in Latvia?

Yes — wind turbines in Latvia can be installed by both private individuals and businesses.

However, installation depends on:

• mast height

• location

• distance from neighbouring properties

• requirements of the specific local municipality building authority

Each project is evaluated individually.

What permits are required?

For small and medium wind turbines, the process is often simpler than it initially appears.

🟧✓ approval from the local municipality building authority is required

🟧✓ for smaller projects, simplified approval procedures are often sufficient

🟧✓ above ~20 m, a full construction project is usually required

Requirements may vary depending on the specific location and municipality.

Mast height — why is ~20 m an important threshold?

In practice, for small and medium wind turbines (~5/10/20/30/50 kW), the optimal mast height is usually up to ~20 metres.

This provides:

• sufficient wind flow

• simpler approval procedures

• faster installation

• lower costs

Above ~20 m:

• a full construction project is usually required

• approvals become more complex

• costs and project timelines increase

Where can a wind turbine be installed — and where does it make sense?

The most important factor is not only permits — but choosing the right location.

An incorrectly selected location can reduce turbine efficiency several times over.

Wind turbines operate most effectively in:

• coastal areas

• open rural locations

• elevated areas without obstacles

Recommended average wind speed for efficient turbine operation:

• from ~6 m/s and higher

• 
  

How does the approval process work in practice?

In many cases, the process is simpler than expected.

• approval from the local municipality building authority is usually sufficient and, if required, a visual representation of the proposed solution

• requirements always depend on the specific location

• there is no single universal scenario — but in most cases, projects can be implemented without complicated engineering procedures

  
  

How much does a wind turbine cost?

Costs depend on several factors:

• power capacity (5/10/20/30/50 kW)

• mast height

• installation location

• grid connection solution

An accurate price can only be determined after evaluating the specific property and project requirements.

Available government support

Several financing opportunities are available in Latvia for small and medium wind turbine projects.

ALTUM

🟧✓ intended for companies and legal entities

🟧✓ loans, guarantees or capital discounts

🟧✓ suitable for energy efficiency and renewable energy projects

🟧✓ can be combined with solar panels and battery systems

🟧✓ support amount depends on the specific programme

• suitable for businesses looking to reduce long-term electricity costs

• 
  

LAD (Rural Support Service)

🟧✓ intended for farmers and food producers

🟧✓ support may reach up to ~40–80% of project costs

🟧✓ applies to energy efficiency and renewable energy solutions

🟧✓ specific conditions depend on the programme and the farm

• one of the strongest financial support instruments for rural areas

• 
  

EU funds and EKII programmes

🟧✓ periodic support programmes available for companies and private individuals

🟧✓ support for energy efficiency and renewable energy projects

🟧✓ more commonly focused on solar panels and battery systems

🟧✓ possible integration with wind solutions in hybrid systems

🟧✓ support typically ~30–50% (depending on the programme)

• it is important to follow current funding calls and programmes

  
  

Most common mistakes

The most common mistakes in practice are:

• incorrectly selected installation location

• overly optimistic wind assessment

• mincorrectly selected system size

• unverified solutions without real-world experience and calculations

These factors most often determine the final project result.

Conclusion

Installing small and medium wind turbines in Latvia is not as complicated as it may initially seem.

The key factors are:

• correct location selection

• appropriate system configuration

• professional approach

• a properly selected financing model can significantly reduce costs and accelerate project payback.
