Due to cheap electricity in China, large mining farms are often located near hydropower plants.
Just keep in mind that with the great potential of the terrain for the construction of hydropower plants, it is technically impossible to technically implement such a project. In some cases, a sheepskin will not be worth the dressing.
Ive been studying this topic for a long time (power engineer by occupation), in world practice there are already underwater hydro generators that can be lowered into the water stream and fixed. The cable along the cable is brought ashore, where the stabilizer control cabinet stands. But they are expensive in price and probably in operation.
