Efficient District Heating


Detailed description of the Good Practice

District heating is a safe and environmentally good way of heating houses and industries. In Göteborg district heating started in the Kortedala suburb the 24th of August, 1953. Today a 700 kilometer long pipe connects about 90 percent of all apartment blocks in Göteborg and industries and workplaces. For one-family homes only 4000 are connected but the goal is to have 16000 by 2010.

Energy, energy efficiency

Objectives of the Good Practice

To produce energy for heating in ecological ways.


  • 2/3 of all district heating is produces from waste water, industry and waste incineration.
  • In 1970 90 percent of the heating was produced by oil. Today almost no oil is used.
  • The emission of nitrogen dioxide has halved in 20 years even though the energy used has doubled.
  • During the same period the emissions of sulphur and nitrogen oxide has been reduced by 98 and 85 percent respectively.

More Details of the Good Practice

The whole district heating system contains 20 heating facilities of which 3 are large. Some small ones at the end of the system are only used for supporting the system during winter. A couple are only used in reserve. About 20% of the energy supplied in Göteborg is renewable. It comes from the waste incineration at Sävenäs, bio fuels and from electricity from hydroelectric power and eleven wind turbines. The rest of the district heating is produced by Göteborg Energi's power and heating plant at Rosen Lund, and at the high-temperature water stations. Natural gas, bio fuel and oil are used for this. In the summer the district heating energy is used to cool the buildings.

Hot water from the refinery and hot water from the waste-water treatment also contributes to district heating during the whole year. Waste heat from the refineries and the incineration plant at Sävenäs accounts for almost three-quarters of the district heating, together with heat from heat pumps at the Rya sewage treatment works. The use of waste heat entails reusing energy, which has made Göteborg’s use of energy more efficient and thereby reduced the consumption of energy. The amount of energy supplied is about 10% less than the energy used. We use in other words more energy than that which is supplied. This is possible through the reuse of energy.

The total amounts of production of central heating were 3900 GWh for 2002.
