Hydro Power Plants

Hydro power plants, especially, the underground power houses, like the project I was responsible for, are simple in design but require a massive civil construction work. These include excavation, gradual concreting and embedment of equipment. Following are some pictures from different projects I had involvement with that show the scale of equipment and construction works.
