There haven’t been any research on the explicit analysis of the air pollution of thermal power plants in the Beijing-Tianjin-Hebei region so far. Our research team has established a comprehensive emission inventory of thermal power plants in the Beijing-Tianjin-Hebei region (BTH-Power Plant Version 1.0) on the basis of data generated during online monitoring, environmental impact assessment, and acceptance of thermal power plants. Taking 2011 as the base year, the research of BTH-Power Plant version 1.0 covers Beijing and Tianjin, as well as all 11 cities in Hebei Province (i.e. Shijiazhuang, Tangshan, Handan, Xingtai, Hengshui, Cangzhou, Zhangjiakou, Chengde, Qinhuangdao, Langfang, and Baoding)  The research data is mainly derived from online monitoring, environmental impact assessment, and acceptance, of which online monitoring data comes from online monitoring system by Bureau of Environmental Supervision, MEP for key pollution sources, while environmental impact assessment data and acceptance data are from thermal power projects approved by MEP over the years. Compared to existing ones, the thermal power emission inventory provided by this research has been substantially advanced:

(1) It is the first time that thermal power emission inventory has been generated based on online monitoring data in China., which breaks through bottleneck caused by traditional emission factor method, and significantly promotes the temporal resolution of pollution source emission inventory.

(2) Emission data is completely based upon statistics from authoritative departments in Ministry of Environment Protection. The environmental impact assessment data, acceptance data and online monitoring data can be supplemented and compared with each other, which ensure data reliability.

(3) The acceptance data and online monitoring data are the existing status of emission data, which can effectively solve the problem that the eliminated thermal power units are included in the statistics in the traditional inventory. According to the calculation in BTH-Power Plant version 1.0, the locations of thermal power plants in BTH area are described in following figure.
