Note: Under the influence of factors such as constant rise in the primary energy price, the motivation of local plants to start
operating has been declining and the situation of peak power generation of local plants is not optimistic. Therefore, the typical
start-up mode of local plants shall be determined in a conservative way. The overall output of local plants on the FOSHAN grid
in summer heavy load in 2008 is significantly less than the maximum output of local plants in 2007.
