How much does a hydro-electric dam cost?

Answer 1

Dams are very expensive, so they aren't a very good idea in low economically developed countries (even though they are great help to prevent flooding). Remember also that prices vary depending on when they are built, how large they are, and many other factors.

Some examples of building prices:

• Itaipu Dam: $20 billion
• Hoover Dam: $49 million
• Fontana Dam: $70 million
• Tarbela Dam: $25 million
• Three Gorges Dam: $$22.5 billion

Answer 2

The cost to build a hydro-electric dam will vary as the size and engineering difficulty of the project. There are only a limited number of places to construct a dam. The economic considerations regarding dam building are extraordinary. A large number of people in the area, as well as both up- and down-stream will be affected. The costs associated with and the sociopolitical maneuvering required to begin dam building are staggering - even if they can be accurately calculated. It is usually only the government that can engage in any dam construction.

Answer 3

It usually costs hundreds of millions of dollars to build, but governments don't want people to know how much money they have spent on them because its sooo much.
