Hydroelectric: Who's Involved | GreenTheFuture.com

Hydroelectric generating systems are typically owned by either the government or an organization established for the purpose of the specific hydroelectric dam. Because of the massive scale of these projects, a broad variety of contractors are used in the construction process. With no major owners or builders, like with most other renewable technologies, below is a list of the 25 largest hydroelectric dams.
