BEIJING - China invested a total of 620.7 billion yuan ($98.06 billion) in power projects in the first 11 months of this year, up 9.5 percent year-on-year, the China Electricity Council (CEC) said.

The country's investment in power-generation projects totaled 309.3 billion yuan while that in grid construction hit 311.4 billion yuan, up 0.5 percent and 20.1 percent, respectively.

From Jan to Nov, the country's investment in new energy facilities, including those for hydroelectric power, nuclear power and wind power, accounted for 67.3 percent of the total investment in power-generation projects, up 3.9 percentage points compared with one year ago, the CEC said.

However, the proportion of investment in coal-fired power plants fell by 6.5 percentage points to 29.59 percent during the period, it said.

The CEC warned of a possible risk for a power supply shortage as the increase in the country's power consumption continued to outrun the expansion of its power-generation capacity.

The country had 66.27 million kilowatts of new power-generation capacity in the first 11 months, or 1.02 million kilowatts less than the same period of last year. Its power consumption, however, climbed 11.85 percent year-on-year during the period.
