What is the most expensive part of building a dam to make hydro power?

    The most expensive part of the dam is building the wall itself, since it has to be engineered to stand trememdous pressure constantly, as well as being an extremely hazardous project to work on, so workers have to be paid extra. The actually turbines themselves will cost more in maintenance over the years, but during the building itself, the wall is the majority of cost.

    I hope this helped!
