Questions such as “How do I position myself as a supplier in the context of municipal heating planning?”, “How do I get a complete overview of the local heating demand structure?”, “What happens to my gas networks and how can I replace the business with sustainable heating solutions?”, “Where do heating networks actually make sense from a business perspective?” and “What financing options do I actually have for new heating infrastructures?” were discussed with exciting perspectives and insights.

The Kelvin Green HeatMap and Kelvin Green Transformation Planner tools, which are helpful for the heating (network) strategy, were also presented.

The focus was on the following topics:

• New framework conditions in the biogas market
  Overview of the 2025 biogas package and the economic opportunities offered by flexible operation.
• Heat as an additional value-added lever
  Own heating network or partnership with the local supplier – we showed concrete ways to implement this.
• Simulation & planning with HeatSim
  Using a real-life practical example, we demonstrated how the HeatSim tool can be used to transparently evaluate economic efficiency and funding options.

Our most important findings:

• The Biogas Package 2025 opens up new economic prospects – but requires a clear strategic realignment.
• Heat is becoming the decisive second pillar of revenue: whether through your own heating network or as a partner of local suppliers – it pays to think about heat systematically.
• HeatSim can be used to simulate economic efficiency, delivery options and optimum operation in detail – and prepare decisions based on data.

Special thanks go to our guest Uwe Welteke-Fabricius for his well-founded assessment of the regulatory framework and market trends.

If you are interested in an initial strategy meeting, we look forward to hearing from you.

PRESS RELEASE (English version see below)

Simple operation, great benefits for heating network operators

HeatSim was specially developed to easily and efficiently solve the complex challenges faced by heating network operators in the context of the upcoming heat transformation. The software offers extensive functions for optimizing costs, planning and operation:

• Investment optimization: By comparing the full costs of different generators and storage systems over their service life, investments can be optimally planned.
• Tariff optimization: HeatSim supports pricing and contract design as well as risk management based on future operating cases.
• Procurement optimization: Comparing different procurement strategies facilitates price negotiations and strategic decisions.
• Predictive generator deployment planning: HeatSim enables the cost comparison between optimized generator deployment control and the fixed ranking of generators.
• Subsidy optimization: The software calculates BEW, EEG and KWKG subsidies as well as electricity fee income from CHP in the operating scenario.
• Heat network optimization: HeatSim calculates generation cost benefits with different flow temperatures and the use of heat pumps.
• Technical planning support: The creation of operational load profiles and operating points helps to optimize the design of systems such as heat pumps.

“We are already successfully using the Kelvin Green HeatSim interactively in numerous consulting projects with around 30 of our customers. The feedback has been so overwhelmingly positive that we are now delighted to be able to make HeatSim available to a wider audience as self-service software and thus promote the efficient and affordable heating transition.” Martin Bornholdt, Managing Director Kelvin Green

“HeatSim was indispensable for our heat planning.” Thorsten Beyer, Stadtwerke Staßfurt

“As part of the transformation plan for our heating networks in Staßfurt, we made intensive use of the Kelvin Green HeatSim to compare the full costs of various heat generation options in different price development scenarios and to better assess risks. We also saw how high the generation cost savings would be if we lowered the flow temperature to 75°C. It was very easy to use and the findings are indispensable for our heat planning.” Torsten Beyer, Head of Technology at Stadtwerke Staßfurt
