DHC Market Outlook 2026: For the first time, renewable and waste heat sources have surpassed fossil fuels in European district heating networks. Analysis of key figures and the role of digitalization.
Trends for 2026: The Historic Shift in European District Heating Networks
As Europe faces yet another energy crisis—with the closure of the Strait of Hormuz driving gas prices above €60/MWh this spring— Euroheat & Power’sDHC Market Outlook 2026, released on June 10 at the EHP Congress in Krakow, sends a strong message: the district heating and cooling sector is now the most advanced segment in Europe’s thermal decarbonization. And for the first time in its history, renewable energy and waste heat have surpassed fossil fuels in this sector.
This is the key figure for the 2026 edition. In 2024, the share of renewable sources and waste heat in European heating networks reached a record 46.2%, compared with 45.9% for fossil fuels. A symbolic and structural shift, even though fossil fuels still account for more than 70% of all heating and cooling in Europe.
Here are the details:
The rate of growth (+2.8% year-over-year) even exceeds the targets set by the EU’s Fit for 55 package.
This performance is largely due to the rise of "power-to-heat" technologies, which integrate district heating networks with renewable electricity:
The Finnish example illustrates the pace of change: production of heat pumps and electric boilers there tripled between 2019 and 2024, accounting for 10% of the country’s heat supply. Heating networks are becoming flexible consumers of electricity, capable of absorbing renewable surpluses and stabilizing the power grid; a British study estimates this systemic benefit at over 4 billion euros per year.
Despite a slight decline in heating demand (-1.2%, due to milder winters and improved building efficiency), the infrastructure continues to grow: 1,559 kilometers of new pipelines were laid in Europe in 2024, bringing the total to over 201,000 kilometers. Denmark (+714 km) and France (+429 km) alone account for more than 70% of new developments.
The pace of grid connections remains strong: in France, an additional 2,374 buildings were connected to the grid in 2024 (+5%), and the report projects that more than 2.2 million additional households will be connected by 2030 in countries with available data alone. A clear signal for operators: the customer base is growing, and with it the complexity of the networks they must manage.
This is one of the most interesting highlights of this year’s event: Euroheat & Power is dedicating an entire section to digitalization as a critical catalyst for innovation in the sector. Advanced modeling, real-time data analysis, and artificial intelligence: these tools enable operators to better forecast demand, manage peaks, and optimize the balance between multiple heat sources.
The report also highlights a less obvious benefit: digital tools reduce the cost and complexity of network planning, thereby eliminating one of the main bottlenecks in deployment. As energy mixes become more diverse (heat pumps, waste heat, storage, solar thermal), smart management is shifting from an option to a prerequisite for performance.
Following a 2024 that was among the hottest on record, district cooling sales reached 3.3 TWh (+3%), driven by more than 200 networks across Europe. France is aiming for 2.5 to 3 TWh by 2035, with the Paris network set to triple in length by 2042. District cooling is emerging as a key tool for relieving the strain on the power grid during heat waves.
From a regulatory standpoint, 2026 marks a turning point: the April 2026 AccelerateEU communication explicitly mentions the deployment of district heating networks as a crisis response for the first time, and the European initiative on electrification and heating expected this summer is expected to shape support for the sector. The report’s message is unambiguous: the sector no longer seeks recognition; it demands the conditions for delivery, investment visibility, local thermal planning, and frameworks that reward flexibility.
Conclusion
The 2026 edition marks a turning point: European district heating networks have evolved from a mature infrastructure to the backbone of an integrated, flexible, and largely carbon-free energy system. But this new complexity—involving multiple sources, integration with the electricity grid, storage, and a growing customer base—can no longer be managed based on intuition alone. It must be managed using data.
At Dyneo, this is precisely our belief: leveraging operational data is the key to identifying anomalies, optimizing workflows, and ensuring the high performance of tomorrow’s heating networks.
