Jiamusi in China: a heating
network to deal with extreme cold
Jiamusi, a city with 2.5 million residents,
is located in the northeast of China, where
conditions in winter are extremely harsh,
with the average temperature in December
and January reaching –18 °C. The city’s heating
network is 25 years old. Made of simple primary
networks and with no computerized
management system, it had become obsolete.
In May 2007, the municipality turned to
Dalkia to operate and develop the network.
It was the fi rst heating network in China
for which operation was awarded under
a concession model.
Fast action was needed. Around 30 employees
carried out the annual service, applied technical
modifi cations, and prepared for the installation
of around 100 substations. The heat came back
on on October 15. This success will play a part
in Dalkia’s expansion in China.
The network now provides heating for
250,000 people, as well as for stores and
municipal buildings—in all, a total surface of
5.5 million square meters. By 2020, the network
should be heating close to 15 million square
meters of buildings.
