The energy structure of Henan Province is dominated by coal，and the main pattern of coal power is difficult to change in the short term，which poses challenges to the coordinated development of economic society and the ecological environment.This article summarizes the development of the energy conservation and environmental protection benchmarking activities of coal power units in Henan Province since 2017，analyzes the trends of energy consumption，water consumption，and environmental protection indicators of coal power enterprises in the province.Since the implementation of the benchmarking activities，Henan coal-fired power units have achieved significant results in energy conservation and emission reduction，and have achieved good results in improving corporate operating efficiency.During the “14th Five-Year Plan” period，it is recommended that Henan continue to carry out coal power energy conservation and environmental protection benchmarking activities，promote energy conservation and environmental protection technology upgrades，and strengthen energy conservation and environmental protection operation monitoring and supervision.
