Smart district heating and cooling grids - demand

District heating and cooling grids cover the generation and distribution of thermal energy in district networks. Smart district heating and cooling grids aim to improve the management of energy demand. Such networks are optimised through the use of new technologies including heat meters and heat substations (heat exchangers). New energy control functions of substations include monitoring and control via the internet or digital radio. At the consumer end, in hot water and radiator systems, new devices such as variable-speed radiator pumps may be required.

These systems, supplying predominantly residential buildings and districts, are able to de-couple fluctuations in the heat demand of buildings from the network conditions – in other words, they smooth demand peaks – without perceptible changes in comfort. This allows the network’s heat demand to be stabilised, energy efficiency to be improved, and heat (or cooling) loss in the supply network to be reduced by up to 20%.

List of projects where this technology is being implemented.

STORM

The STORM project tackles energy efficiency at district level by developing an innovative district heating & cooling (DHC) network controller. It aims to demonstrate that thanks to a smart DHC network controller energy savings can reach up to 30%. In that perspective, the project partners will...

REPLICATE

The REPLICATE project will generate smart city business models, and tailor-made solutions in the areas of energy, transport and ICT. There will be pilot actions in energy efficiency, efficient and sustainable transport and integrated infrastructures. The key to the project’s approach is in...

OPTi

The OPTi project aspires to create a long-lasting impact by rethinking the way district heating and cooling (DHC) systems are architected and controlled. The overarching goal is to create business benefit for the industry as well as to ensure optimal end-consumer satisfaction. OPTi will deliver...

Interopertional payment system Control system...

STORM Site Heerlen

In Heerlen (the Netherlands), flooded mine galleries act as a renewable heat source and provide a total of 500,000 m² floor area connected to a low temperature district heating and cooling network. This system consists of two hot wells in the northern part (water with approx. 28°C) and two cold...

OPTi Site Lulea

The district heating and cooling (DHC) system in Luleå (Sweden) supplies 31,000 households with heating and cooling on a daily basis. The heat is manly produced at a CHP plant close to the city center. It supplies the base heat production of 185 MW to the grid and gets the fuel (e.g. flue gas) from...

CELSIUS Site Gothenburg

In Gothenburg a large amount of waste heat, from both waste incineration and industries, is used in the district heating system. There is also heat pumps taking care of the heat in sewage and plants using bio fuels such as wood pellets, wood chips and bio oil. There is also a district cooling ...

CELSIUS Site London

To supply new heat users​ , the existing Bunhill Heat and Power Network in London will be extended to utilise existing sources of waste heat and to explore the opportunities for the system to utilise a lower operating temperature. This demonstrator will develop knowledge and expertise of how to...
