Daily hydropower generation gained 12 percent from two weeks earlier to 2.31 billion kilowatt-hours in mid-June. 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.
