BEW Funding – Key to Climate-Neutral Heat Supply

The Federal Funding for Efficient District Heating Networks (BEW) is Germany’s most important funding program for climate-neutral district heating: feasibility studies receive up to 50% funding (max. 2 million EUR), while investments in new construction and transformation are funded at up to 40% (max. 100 million EUR). Key requirements include a minimum 75% share of renewable energy, a maximum supply temperature of 95 °C for new networks, and a decarbonization roadmap to 2045. The program covers all project phases from planning through to operating cost subsidies over 10 years.

What is BEW Funding?

BEW supports the construction of new district heating networks with high shares of renewable energy as well as the decarbonization of existing networks. The goal: climate-neutral heat supply by 2045.

The Four Funding Modules

Module 1: Feasibility Studies

• Funding level: Up to 50% of costs
• Maximum amount: 2 million euros
• Purpose: Planning and conception of district heating networks

Module 2: Systemic Funding

• Funding level: Up to 40% of eligible costs
• Purpose: New construction of district heating networks or transformation of existing networks

Module 3: Individual Measures

• Funding level: Depending on the measure
• Purpose: Individual investments to improve existing networks

Module 4: Operating Cost Subsidies

• Funding level: Up to 90% of additional costs
• Duration: Up to 10 years
• Purpose: Support for operating large heat pumps and solar thermal systems

Requirements for Funding

1. Minimum size: The district heating network must supply at least 16 buildings or building units.
2. Renewable energy: At least 75% of the heat must come from renewable sources.
3. Transformation plan: For existing networks, a transformation plan is required.
4. Economic viability: The economic viability of the project must be demonstrated.

How VICUS Districts Helps with Funding

With VICUS Districts, you can:

• Create feasibility studies: Detailed network planning and simulation for Module 1
• Demonstrate economic viability: Calculate investment costs and operating costs
• Develop transformation plans: Analyze existing networks and plan decarbonization
• Document funding requirements: Export calculation results for funding applications

Application Process

Applications are submitted through the Federal Office for Economic Affairs and Export Control (BAFA). Early planning is important as funds are limited.

Conclusion

BEW funding offers significant financial support for the transformation of heat supply. With professional planning software like VICUS Districts, you can efficiently meet the requirements and maximize your chances of receiving funding.
