Jinneng Hongdong thermal power plant in Zhaocheng Coal Chemical Industrial Park in the northeast of Hongdong county is adjusted to Guodian Huozhou Power Plant in Xinzhi town of Huozhou city according to the special plan for central heating in Hongdong county (2015-2030). The layout of long-distance heating pipeline and primary heating main network needs to be adjusted immediately. The long-distance heating pipeline is arranged along G108 national highway and S224 provincial highway from north to south, passing through ticun Township and Zhaozhou Towns, Hongdong County, Ganting Town, and finally reach Linfen City.
