The power generation of Yushe Power Plant, Huaiyin Power Plant, Jining Power Plant, Yingkou Power Plant and Sichuan Hydro Power increased significantly. The increase in power generation of the Company's power plants was mainly attributable to the following reasons: 1. Newly acquired power plants, such as Luohuang Power Plant, Yueyang Power Plant, Yingkou Power Plant, Jinggangshan Power Plant, Pingliang Power Plant and Sichuan Hydro Power have made significant contribution to the increase of the Company's generation; 2. Stable generation capacity contributed by six newly operated generating units at Yushe Power Plant, Qinbei Power Plant and Huaiyin Power Plant; 3. As a result of rapid economic growth, power consumption in the regions where the Company's power plants operated underwent continued growth, thereby providing favorable conditions for the growth of the Company's power generation.
