in improving district energy efficiency
in Eastern Europe where Dalkia has
become a major district heating provider.
Similar to Europe, China has set a fixed
heating temperature of 18 degrees C
( 64 degrees F) for building interiors,
which contributes to effective energy
management. In China, Dalkia now has
existing operations in Jiamusi, Harbin
and Chongqing (table 1). (While Jiamusi
and Harbin are located in northeastern
China, where the government allows foreign investors to have a majority stake in
district heating systems, Dalkia’s majority share in the Chongqing combined heat
and power system, located in southeastern China, was also allowed as it is an
industrial CHP system and therefore not

Dalkia first started exploring the possibility of entering the heating market in
Jiamusi in 2005. The company assessed
that the city’s total service area for heating
from all sources – district heating, block
boilers, individual heating, industrial heat,
etc. – was 18. 9 million sq m ( 7. 3 sq miles).
Of this, Dalkia determined that 14. 5 million sq m ( 5. 6 sq miles) could be connected to its district heating network.
The urban heating network of
Jiamusi Heating Company (JHC), a com-
pany owned by the municipality, was
already supplying 29 percent of the total
heating surface, i.e., 5. 5 million sq m ( 2. 1
sq miles). JHC’s demand peaked at 410
MWth, 70 percent of which was supplied
by two local CHP plants: Heilongjiang
Huadian Jiamusi Electricity Generation
Co. Ltd., owned by one of the top five
Chinese power-generating companies and
located in the eastern part of Jiamusi;
and Jiamusi Longshi Thermoelectricity
Co. Ltd., owned by the municipality and
located on the west side of the city. The
rest of JHC’s demand was supplied by
the company’s own peak-load boilers.

The project took two years to
materialize as it was the first concession
agreement in the heating sector in China.
Now, after two years of operation, Dalkia
Jiamusi has increased network coverage
by 56 percent to 8. 6 million sq m ( 3. 3
sq miles), where 73 percent of Dalkia
Jiamusi’s customers are residential and
37 percent are nonresidential, including
commercial and public buildings. The
company aims to provide district heating
service to a geographic area covering
14. 5 million sq m ( 5. 6 sq miles) by 2020
