FOCUS BIG MARKETS: CHINA & POLAND
By Mikael Jakobsson, Managing Director, NXITY, Executive Director, APUEA (Asia Pacific Urban Energy Association), Advisor, EU H2020 MAGNITUDE project
The Chinese district energy sector is developing in multiple aspects and new business opportunities emerge. The District Heating market expands into new geographical areas, and while the district heating growth is slowing down, the growth of the district cooling market is increasing. This is the perspectives of a localized consultant. While our focus, ten years ago, was on planning and design of new district heating systems, the main focus today is on modernization (of existing district energy systems), operation optimization and development of Multi-Energy Systems (MES), District Energy 4.0/Smart District Energy schemes and Smart Energy City (SEC) solutions. Ten years ago, there was only one famous private owned district heating (DH) company (utility) in China, namely Shenyang Huitian District Heating company. Today, there are several large private owned DH companies with DH systems in multiple cities. Even state-owned and municipality-owned DH companies are expanding to multiple cities. DISTRICT HEATING DEVELOPMENT The building floor area covered by DH in northern China has almost tripled in the last decade, covering over two-thirds of the total heating area. This represents approximately 800 GW and 5,000 TWh. Partly, as a result of the central governments “go-west” policy, the DH floor area has increased more than 300 % in provinces like Inner Mongolia, Qinghai and Shanxi in the last decade. In Shaanxi, the DH floor area has even increased more than 600 %. This is to be compared with the increase of the DH floor area in i.e. Heilongjiang, Jilin and Liaoning, where the increase is less than 150 %.
Hohhot Low-Carbon District Heating Project, Inner Mongolia Autonomous Region Modern Chinese district heating project of international standard. Quality along the entire project value chain has been prioritized; from planning to operation.
Project owner:
Hohhot Chengfa Heating Co., Ltd.
Implementation period:
2014-2020
Owner’s engineer: Design Institute:
NXITY
North China Design Institute
Project information: i) 30 km DN1400 transmission pipeline for utilization of surplus heat from remote power plant. ii) merging of five DH systems into two pool operated DH
systems; 2.3 GW and 0.9 GW respectively. iii) 116 km new district heating network.
iv) 2 x booster pump stations (7,500 m3/h, 140 mwc). v) emergency sectioning and leak detection system. vi) integration of curtailed wind power for heat production.
DH has also been developed in the central and southern parts of China in the last decade, despite the lack of policies and regulations in this region. From Chongqing in the west, to Shanghai in the east and Hunan in the south, DH has been implemented in many cities. Both district heating and district cooling are often feasible in this region, and therefore Combined Cooling, Heating and Power (CCHP / Tri-generation) and combined District Heating and Cooling Systems (DHCS) are relatively common. Already in 2011, the National Development and Reform Commission (NDRC), Ministry of Housing and Urban-Rural Development (MoHURD),
