Outstanding district heating network performance

In Harbin, northeast China, Dalkia is building and operating a heating network that offers outstanding performance, monitored in real time.



Harbin is home to 9.5 million people, making it one of China's 10 most populated cities. It also faces extremely tough weather conditions, with annual temperatures averaging just -9°C. Following the acquisition of a majority stake in Chinese company YangGuang, Dalkia won a local-government contract to provide a new heating network in the southwest section of the city in 2007. The network is expected to supply heating to 33 million square meters of floor space in buildings across an area of 52 square kilometers by 2020. The goal is to reduce pollution from coal-fired power plants and halve greenhouse gas emissions.


The new network has already made it possible to shut down a number of standalone heating plants and smoke stacks in the area covered by the contract. Dalkia's expertise in optimizing services – particularly through the use of facilities incorporating circulating fluidized bed (CFB) and combined heat and power (CHP) technology – have significantly reduced the emissions of greenhouse gases and dust caused by burning fossil fuels.


Dalkia has also developed a tailored management system that uses sensors to measure variations in energy use in real time and quickly detect any problems. This has led to a 40% increase in energy efficiency.
