The power generation of Dezhou Power Plant, Jining Power Plant, Xindian Power Plant, Huaiyin Power Plant and Yushe Power Plant 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 and Pingliang Power Plant have made significant contribution to the increase of the Company's power 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 demand in the regions where the Company's power plants operated underwent continued growth, thereby providing favorable market conditions for the power generation of the Company; and 4. Safe and stable operation of generating units has ensured the growth in the Company's power generation.
