China’s Hydroelectric Generation Gains, Power Shortage Eases

China’s hydropower generation rose in June after the eastern and central regions received rainfall, easing an electricity supply shortage, the nation’s top economic planner said.

Daily hydropower generation gained 12 percent from two weeks earlier to 2.31 billion kilowatt-hours in mid-June, the National Development and Reform Commission said on its website today. Rainfall that has increased hydropower production also reduced the use of air-conditioners, easing electricity shortages “noticeably” in Chongqing municipality and the provinces of Zhejiang, Hunan and Anhui, the agency said.

About 20 provinces started rationing electricity this year, the official Xinhua News Agency said May 3. Regions served by the State Grid Corp. of China may face a shortfall of 40 gigawatts this summer, surpassing China’s worst in 2004, as demand rises, the nation’s dominant power distributor said on May 24.

Only Shanxi and Hebei provinces, among the 26 provinces served by State Grid, have limited electricity use since June 10, according to today’s statement.

Power supply remains tight in southern China because of high temperatures and insufficient coal supply, it said. Power shortages in six provinces managed by Southern Power Grid Co. reached 8.38 gigawatts on June 10, it said.
