China's power production in July rose 4.21 percent from last year to 348.5 billion kWh, growing faster than in June and hit a record since the begging of 2009, according to State Grid Distribution Center.

It was the second month in a row that power output grew after a 3.59 percent annual rise in June.

Temperature was the key factor that influenced the power consumption in July. The decline of the late July compared with middle and earlier of the month was because of the heavy rains pounded in most of China.

Chinese power generation volume had declined in year-on-year terms for eight consecutive months beginning in October last year, when the then-slowing economy weighed on heavy industry.

Chinese national electricity output in July hit 348.5 terawatt hours, Xinhua cited the State Grid Corporation of China as saying.
