Supplying energy-efficient heating and cooling through a collective system
District energy is about securing an energy-efficient heating and cooling supply through a collective system. Put simply, district energy is about moving energy in water, with a valuable temperature, from a place of production to the place of consumption.
District energy is feasible around the world where there is a concentrated need for heating or cooling, e.g. in industrial zones or densely populated areas both in large and small cities.
Co-generation of electrical and thermal energy at Combined Heat and Power (CHP) plants enables efficiency levels above 90 per cent, making it a very cost-effective way of heating and cooling buildings.
We invite you to explore district energy solutions in more depth below, find potential partners, catch up on the latest district energy news and discover real-life case examples of how district energy technology can help solve your energy challenges.
Denmark’s energy consumption fell by almost 4 per cent in 2019 after a large decline in the consumption of coal in particular, while the consumption of wind power and biogas pulled in the other direction. The development meant that CO2 emissions from energy consumption dropped by more than 9 per cent. More than two thirds of Danish electricity consumption is now covered by renewable energy.
Yesterday, the International Energy Agency (IEA) launched its World Energy Outlook 2020.

Energy-efficient heating and cooling solutions are an ingrained part of the Danish mindset. While many countries have opted for individual, on-site heating and cooling solutions, Denmark decided to focus on collective heating systems after the oil crisis of the 1970s. Today, 64 per cent of all Danish households are supplied by district heating, contributing to making Denmark one of the most energy-efficient countries in the world. The efficiency of the system is created in three parts; creating heated or chilled water, avoiding heat loss in the distribution as well as effective connection and use on the consumer side.
Denmark passed its first heat supply law in 1979. Based on this law, Danish stakeholders have developed a political framework to implement district heating successfully across Denmark and thereby gained valuable experience over the past four decades. This has also spurred the growth of numerous companies that deliver state-of-the-art technologies and know-how within all parts of the value chain of district energy systems.
Co-generation of electrical and thermal energy at Combined Heat and Power (CHP) plants enables to reach efficiency levels above 90 per cent, making it a particularly efficient and cost-effective way of supplying heat and cooling in densely populated areas. An example is the Danish capital Copenhagen, where 98 per cent of the households are supplied by district heating. Also, district heating and cooling are able to utilise all energy sources, including renewables, which allows a flexible and clean production. In fact, 60 per cent of the Danish district heating is based on renewable energy.
Similar to district heating, district cooling possesses immense potential for reducing costs and CO2 emissions. For instance, district cooling systems in Copenhagen can use seawater from the harbour.
In combination with district energy, Denmark also utilises a natural gas grid as well as individual solutions for heating and cooling. Upgraded biogas is fed into the natural gas grid and heat pumps are increasingly used for individual heating solutions. Large heat pumps are also used at various CHP plants to help integrate surplus renewable power into the thermal energy system and thereby balance the energy system.
With more than 100 years of experience in district heating, Denmark hosts some of the world’s leading suppliers in the fields of district heating and cooling, as well as in waste-to-energy. Their technologies, solutions and knowhow can serve as inspiration for other countries looking for energy-efficient heating and cooling systems.
