37th Euroheat & Power Congress27-28 April 2015, Tallinn, Estonia
Organised by
DH in Mongolia –Energy efficient and cleaner heating in Ulaanbaatar
Erbar Agarjav,Ulaanbaatar District Heating Company, Mongolia
Country feature:
Land area 1,553,556 sq km, 19th rank in theworld
Population 3.0 million, 45% lives in Ulaanbaatar
Mongolia is ranked 15th in the world for coalresources.
Climate condition:
Mongolia is high elevated cold, and windy. It hasan extreme continental climate.
Getting to know Mongolia
Type of heat resource province’s centre
Combined heat and power station – 4
Heat plant – 5
Heat only boiler – 9
The winter is cold with Januaryaverages dropping as low as −35 °C. Avast front of cold, heavy, shallow aircomes in from Siberia.
Mongolia has 21 province, western provinces more cold during winter…
Mongolian district heating system OVERVIEW
Ulaanbaatar, the capital and also the largest city in Mongolia. And the most coldestcapital city in the world. Thus, heating is most important factor for living in comfort.

Heat efficiency in Ulaanbaatardistrict heating sector
Before Heat efficiency project, 1996
The Power Plants and substations used fixed speed pumps, constant flow,
Over heat, no energy-saving, lack of regulating technique
Consumers paid according to the volume of buildings, no awareness aboutefficiency of heating system.

Our focus on future: Thermo Technical Rehabilitation project
Reduce the demand of some 500 pre-cast panel apartment buildings that were built between 1965 and 2000.

Conclusion Extend corporation with leading district heating companies to shareexperience and know-how and bring out new technology such as peakload boiler, waste to energy and heat accumulator.
Well sequenced, comprehensive institutional reform and management./PPP, Leasing, privatization/
Support consumption covering tariffs motivate energy savings. Especially for residential inhabitants.
Expand DHN or develop individual heating network to reduce air pollution from ger areas with PPP
Develop Thermo Technical Rehabilitation project with PPP
