Imagine an intelligent, competitive and liveable city. Imagine a resource-efficient city with smart heating and cooling. This is your city – a CELSIUS city.

CELSIUS City has established an intelligent heating system covering virtually all the households and commercial buildings in the appropriate high density areas of the city and an energy efficient district cooling system for its commercial customers. These systems make use of a range of excess heat sources all created within the city during the course of an average operational day, for example from various industrial and datacentre activities, heat extracted from sewage and bio-based heating. CELSIUS City not only consumes much less fossil fuel generated energy than a traditional European city; but it also plays a fundamental role in supporting the resilience and security of the electricity network by effectively utilising existing network capacity for connecting new distributed generation and for providing grid balancing. This becomes more relevant via thermal storage, when excess renewable electricity, generated for example by wind turbines, is being supplied into the grid. ​

The community, including citizens, politicians, industry and utility as well as other stakeholders, see the CELSIUS City vision take form and recognise and promote the advantages of working together towards a common goal: Improved air quality, reduction of energy use, maximising the use of various kinds of waste, excess, energies and resources. Not to forget all the green business opportunities and the promotion and increased attractiveness of the city as well as security of energy supply.
