From Data Centres to District Heating

Across the Nordics, a new and impactful energy trend is emerging, reusing waste heat from data centres to supply district heating networks.

Excess heat from large data centres is being captured and fed into municipal systems, covering a significant share of local heating demand and dramatically reducing reliance on fossil fuels. What was once waste energy is now a valuable, low-carbon heat source for thousands of homes.

As digital infrastructure expands, so does the opportunity, offering:
✔️ Higher overall energy efficiency
✔️ Lower CO₂ emissions
✔️ Smarter integration between power, data and heat networks

For district energy systems, this isn’t just innovation, it’s the next natural step in sustainable urban development.

Cetetherm´s district heating solutions are enabling the energy transition.
