Chinese Hydropower Output Curtailed
Sustained heavy rainfall in south eastern China has led the Three Gorges Dam and the smaller Gezhouba Dam to cut hydropower generation substantially in order to alleviate flooding downriver, Reuters reports. The Three Gorges Dam (the world’s largest power station with generating capacity of 22,500 MW) has reduced power generation from 18.1 GW to 6.0 GW, while the Gezhouba dam has lowered generation from 2.9 GW to 1.5 GW. In the short term this could lead to a stronger July than expected for thermal power generation, however, it will also serve to replenish reservoirs serving other hydropower projects in the region. For guidance, hydropower accounted for around 8% of Chinese electricity production in May.
