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 gerenating units has ensured the growth in the Company's power generation.
