At present, the largest power generating facility ever built is the Three Gorges Dam in China. The facility generates power by utilizing 32 Francis turbines each having a capacity of 700 MW and two 50 MW turbines, totalling the installed capacity to 22,500 MW, more than twice the installed capacity of the largest nuclear power station, the Kashiwazaki - Kariwa (Japan) at 7,965 MW. As of 2017 no power station comparable to Three Gorges is under construction, as the largest under construction power stations are hydroelectric Baihetan Dam (16,000 MW) and Belo Monte Dam (11,233 MW).
