On October 5, the concrete pouring of the last silo of the underground powerhouse on the left bank of the Three Gorges Group's Baihetan Hydropower Station was completed, marking the full roof of the world's largest underground powerhouse.

Baihetan Hydropower Station is the largest hydropower project under construction in the world, with a total installed capacity of 16 million kilowatts. There are 8 sets of 1 million kilowatt single-unit hydroelectric generating units with completely independent intellectual property rights in the underground powerhouses on the left and right banks. The single-unit capacity ranks No. One. After the roof of the underground powerhouse on the left bank is fully capped, it will be fully transferred to the unit installation stage, and will fully sprint to the scheduled commissioning of power generation targets.
