Hydropower remained a prime renewable energy source in China in 2017 given its efficiency, economy and comprehensive utilization rate.
China's hydropower output reached 1,194.5 TWh in 2017, up 1.7% from the year-ago level and accounting for 70% of total renewable energy power output, showed data from the National Energy Administration.
The volume was also four times as high as wind power output and ten times the amount of photovoltaic power generation during the same period.
The installed capacity of hydropower units was 341 GW last year, much higher than capacity of wind and photovoltaic power at 164 GW and 130 GW.
The curtailment of hydropower stood at 51.5 TWh in 2017, and its utilization rate reached 96% or so.
Its average on-grid power price was only half of wind power price and one third of photovoltaic power price.
In 2017, china's renewable energy plants generated 1,700 TWh of electricity, taking 26.4% of total power output.
By end-2017, installations of China's renewables reached 650 GW, accounting for 36.6% of total power installations.
