BEIJING, Jan. 21 (Xinhua) -- The State Grid Corporation of China (SGCC), the country's largest electric power transmission and distribution company, said Saturday that the power supply will be sufficient during the upcoming Spring Festival holiday.

Thermal power plants currently have 89.34 million tonnes of coal, which is enough for 20 days of power generation.

Meanwhile, the country's electricity consumption is expected to fall by 40 percent during the holiday which lasts from Jan. 22 to Jan. 28, as many factories suspend production during the period, SGCC said.

The company said it will keep a close eye on the cold weather, strengthen inspections and maintenance of high-voltage grids, and take precautions to minimize the impact of snow and freezing rain on power transmission.
