Heating and Cooling Networks

Cogeneration plant serves Harbin southwest area

Harbin Southwest Centralized Heating Network was initially planned and constructed under the supervision of Harbin Municipality in accordance with Harbin urban construction plan. In 2007, Veolia won the bidding from the state-owned committee organized by Harbin Municipality, and completed the construction of phase I infrastructures of this heating network in the same year. Equipped with 5x58 MW heating capacity by hot-water boilers, Veolia began its first heating season from October 2007 to April 2008 and added the sixth additional 58 MW hot-water boiler the following year. By 2015, the total heating surface of phase I reached 19.7 million square meters. 

573 small coal-fired boiler houses, 356 chimneys were removed while the network connected to the main plant and substations were built in following heating seasons. The construction of phase II (cogeneration) began in 2011 and operation started in 2013. The phase II is equipped with 2 power generators and 4 steam boilers.

Network expansion in Jiamusi drives for urban environmental progress

After 20 years of service, Jiamusi’s heating network was too old to meet the demand of its urban development. In 2007, Veolia took over the management and operation of the entire central urban heating network under a 25-year concession agreement granted by Jiamusi Municipality.

During the first year of take-over, Veolia rebuilt 11.6 km of the old pipeline, and replaced about 106 regional substations. 64 coal-fired boiler houses were shut down before the first heating season from October 2007 to April 2008. Thanks to the significant environmental progress, Veolia won the "Global District Energy Climate Award” issued by the IEA in Copenhagen in 2009. The mayor of Jiamusi Municipality attended in person and received the award, which was regarded as one of the city’s highest distinction.

Veolia has been conducting renovation of the network in Jiamusi ever since. Up until now, more than 85% of the city’s total heating is provided by Combined Heat and Power (CHP). 11.4 million square meters are connected to the main network. This figure is expected to reach 17 million square meters by 2020, which is equivalent to 73% of Jiamusi’s urban area.

Localized energy solution for district cooling system in Hong Kong

Hong Kong District Cooling DHY Joint Venture (HKDC JV), a JV in which Veolia is responsible for Operation and Management (O&M), was awarded an 8+8 -year design, build and operation (DBO) contract for the first public District Cooling System (DCS) in Hong Kong.

Located on the site of the former Hong Kong Kai Tak airport, the new Kai Tak district comprises a mixed development of offices, shops, hotels, schools and the new regional cruise hub. With a cooling capacity of 284MW, the facility is the first of its kind in Hong Kong to use chilled water as a cooling medium, replacing the traditional air-cooling methods for the air-conditioning system. A total cooling capacity of 81,000 RT (284 MW), derived from sea water helps to reduce the energy cost and environmental carbon footprint.
